    There is a risk of eavesdropping the screen image of an information device by exploiting unintended electromagnetic (EM) emanation. Leakage frequencies can be detected by displaying a specific image (“control image”) on the device. The control image is effective to estimate the source of EM emanation from the device. In this paper, in order to design a more effective control image for estimating the leakage frequency, we compared several control images considering EM emanation in TMDS (Transition Minimized Differential Signaling).

    There is a wide-area distributed FTP service as one of the main services in the Internet. In this system, a FTP server is copied by mirroring to plural servers, and these servers are distributed and installed in a wide area on a network. However, in delivered files, there are a lot of files which are not used at all till it is deleted. It has produced useless delivery traffic and useless accumulation. We consider that one of the big reason is as follows, it performs the file delivery between servers comprehensively, and it does not have the structure of the file delivery which can reflect a server user's demand. In this paper, we consider an application of an on-demand delivery method to the Ring server which is the representative system which utilized large-scale mirror server positively. The proposal method is based on a caching technology, which can improve the efficiency of files and network resources by doing delivery depending on a demand of a user. We evaluated it by experiment, and verified its validity. From the result of this experiment, the unnecessary delivery traffic between servers was able to be stopped, and the use efficiency of file has improved. Therefore, its validity was verified.

    In the present NetNews system, articles are delivered to all servers by repeating of article data between the next news servers. However, the article data delivered by each news server not used effectively. A part of article data is deleted, without being refered at all. It has produced waste delivery traffic and waste accumulation. An effective solution to the problem is an On-Demand delivery system which delivers required article data when requested by a user. To design the infastructure for this system in a actual network and other resources. Then, in this paper, we perform analysis and modeling of delivery traffic for the proposed system. Furthermore, we show the response time characteristic of proposed system in the present network environment. The authors analyzed the delivery traffic in the NetNews system, and the traffic is modeled with a probability-distributions function. Times for data-transfer and server-processing are analyzed using the queuing theory to estimate the response time.

    We developed a network-based, overall multistage support system for children avoiding school and handicapped children. This system provided the following four-stage support. In the first stage, about 16 areas, 480 multimedia Q & A contents were provided. In the second stage, simple virtual counseling by a computer system was provided. In the third stage, professionals provided videophone counseling. Then, in the fourth stage, professionals provided face-to-face counseling for users who had not solved their problems on-line. We made two booths in which the first, second, and third-stage support was provided within two public facilities of Sendai City. The first and second stages were configured for use on the Internet. We analyzed the operating result of this support system for one year and discussed its usefulness. This system suggests a new model for a network-based support system for the future, for school-avoiding children and handicapped children.

    In the present NetNews system, articles are delivered to all servers by repeating transmission and accumulation of article data between the adjoining news servers. However, the article data delivered by each news server is not necessarily used effectively. Some article data is deleted, without being used once. It has produced useless delivery traffic and useless accumulation. Furthermore, the maintenance and management of the system are becoming difficult, because the network traffic between servers and the storage area on server are increasing. To overcome these problems, an On-Demand delivery system which delivers required article data according to the request from a user is effective. It this system, in order to obtain a quick response, the network speed between servers needs to be high-speed. But, network is growing to a broadband network, therefore data transmission time will be improved remarkably. In consideration of such situation, in this paper, we propose an On-Demand NetNews delivery system. This method delivers the articles according to the demand of a user and enables highly efficient delivery. We designed and implemented a method to NetNews system, and we evaluated it by experiment. From the result of this experiment, the use efficiency of article has improved and the unnecessary delivery traffic between servers was able to be stopped.

    Electric contact erosion and transfer at electrodes of electric contact greatly affects on degradation of the performance of contact. In this paper, the authors discuss on visualization of change in surface profile of electrodes by means of digital image processing. The change of surface profile in measurement data is buried under errors caused by diffusion and reflection of light. When the data is processed by ordinary smoothing filter, small component of feature in surface profile is lost, and processing of image enhancement magnifies error components. The authors have proposed a new image processing technique for measurement of surface profile of electric contact to keep detail features and eliminate errors in measurement data. Missing measurement data are interpolated, and errors in measurement data are eliminated keeping profile of edge by using nonlinear equalizing filter. Inaddition, the proposed technique discriminates feature and errors by dynamic filter which coefficients depend on neighboring components. From the result, visualization of change in surface profile is realized by the proposed technique.

    A quantitative investigation on the relationship between arc duration and resistance in Ag contact in air were made by using a contact driving machine to open the contact at low speed (below 1 mm/s), and measured data were analized statistically. The two types of arc (metallic phase arc: short arc, and metallic phase plus gaseous phase arc: long arc) appeared at low opening speed and the type of an arcing has the correlation with the contact resistance. The contact resistance was high after generating long arc, while low after short arc. Characteristics of arc duration was that both of long arc and short arc appeared in period 1, and only short arc appeared concentratedly in period 2, and these states repeated reciprocally. A clear correlation existed between variations of arc duration and resistance

    The effects of both continuous Gaussian noise and burst Gaussian noise on TV picture degradation were studied by using a Gaussian noise generator which can control noise parameters such as power, ACR, duration, and occurrence frequency. The disturbance was subjectively evaluated. The tendency of the picture degradation against the both noises was the same. However, when the noise power was constant, the mean opinion scores for the burst noise approached to those for the continuous noise as increase of the occurrence frequency at constant burst duration.

    Breaking arc durations and differences between the mass of a contact before and after an experiment, that is a quantity of metal erosion and transfer (QMET), were measured in Ag-Pd alloy contacts. The experiments were tried in air at some conditions of voltage, current and opening speed. The characteristics of arc durations and QMET studied how to change due to metal mixing ratios.<br>In a practical Ag 40 wt%contact, the arc duration was not specially longer, and the loss was not more than the others. In Ag 90 wt%contact, the arc duration had a great tendency to be longer at some conditions, and then the loss was much. The arc duration of Ag 20 wt%had a tendency to become long with operations. The characteristics of arc duration and QMET were different due to two ways of fixing a columnar contact from one side to a holder and from two side. The curves of QMET were zero-crossed, and there were the mixing ratio that the QMET became zero for the one of the electrodes.<br>This paper might suggested some way of a design of electrode for heat produced in the Ag-Pd alloy contacts and the possibility of zero QMET.

    The effect of noise parameters on TV picture degradation was studied by using a composite noise generator which can control noise parameters such as power, APD, ACR, and occurrence frequency. The disturbance was subjectively evaluated. The results show that the effect of noise power on TV picture was larger than those or APD and ACR, and the evaluation scores were different with backgraund pictures. The experimental equation was obtained to assume the relationship between the noise parameters and the evaluation scores so that the evaluation score can be estimated when the noise parameters were given.

    Real-time high-quality video streaming for multiple receivers needs low latency, jitter and wide available bandwidth. In this report we use OpenFlow network, we proposed the method with bandwidth efficiency for high-quality video streaming using packet copy and rewrite packet Ether/IP header. Our method, whose feature is like multicast, repeats packet copy in the network using a distinguished address for multiple receivers, hence can save the latency and the bandwidth used to stream. We present the result of practical experiments about jitter and bandwidth that is not measured in previous research for high quality video streaming, showing that the performance of our method is equivalent to that of the existing methods.

    Electromagnetic radiation occurs at the contact boundary surface of a coaxial connector with insufficient torque because of the current that flows into the contact failure portion. The electromagnetic radiation intensity varies depending on the inductance at the contact failure portion, as found by previous studies. In the present paper, to investigate the mechanism of increased inductance at the contact failure portion, we reveal the relationship between the contact point distribution at the contact boundary surface and the increased inductance by considering the latter as the sum of the self- and mutual inductances.

    This paper presents a new intentional electromagnetic interference (IEMI) fault-injection method that can inject transient faults timely at a distance from cryptographic operations. Such IEMI fault injection could pose severe threats to many cryptographic devices assumed that attackers cannot access them directly since it can be used for performing fault analysis. The proposed IEMI fault-injection method injects a block (i.e., period) of continuous sinusoidal waves via cables attached to cryptographic devices instead of immediate electromagnetic pulse used in the conventional methods. The injected EM waves have a temporary impact in the cryptographic module, but not in other components on the device. Another important feature of the proposed method is to employ EM information leaked from the cryptographic operations for the trigger signal of the fault injection. In this paper, we demonstrate that the proposed method can inject faults timely into the final round of an AES hardware through an experiment.

    The intentional electromagnetic interference (IEMI) fault-injection method using continuous sine waves causes random-bytes faults in the cryptographic devices. Therefore, it was difficult to obtain faulty ciphertext available for conventional analysis methods which assumes the specific byte errors in ciphertext. In this paper, in order to identify the number of fault-injected bytes, we describe an identification technique using side-channel information. The feasibility of the proposal method is verified by observation of voltage waveforms between a power line and ground plane of cryptographic module in time domain with time resolution by 1 ns. In our experiment, we employ a real cryptographic device with Advanced Encryption Standard (AES) implemented and a clock glitch generator which can be adjusted by 0.17 ns steps. Through this experiment, we identified that the change of side-channel waveforms correspond to the number of faulty bytes. Moreover, on the basis of this result, we showed that it is possible to extract available faulty ciphertext for the conventional analysis methods.

    This paper describes a new technique to choose faulty ciphertexts available for Differential Fault Analysis (DFA) from those obtained by randomly executing the intentional electromagnetic interference (IEMI) fault-injection method. This technique employs side-channel information as an identifier in order to choose faulty ciphertexts to be suitable for DFA. For a fundamental study, we monitor transient voltage as side-channel information on a cryptographic device in our experiment. As a result, the amplitude of the waveform increased at the timing of fault-injection. This implies that we can choose suitable faulty ciphertexts using such a change of side-channel information in time domain.

    This paper describes the differential electromagnetic analysis (DEMA) on a cryptographic LSI and the reduction effect of information leakage by a magnetic thin film. The correlation coefficients at two points near the cryptographic IP core become large as DEMA was performed at four points on the cryptographic LSI. Each correlation coefficient at these points decreased when the magnetic thin film put on the cryptographic LSI. On the basis of these results, it was verified that the danger of the information leakage exists near the cryptographic IP core. These results demonstrate that the danger of the information leakage can be reduced markedly as the magnetic thin film puts on the cryptographic LSI.

    Increased inductance values and contact resistance in connector contact surfaces due to degradation of connector contact performance have been reported. In particular, inductance increases while degradation remains minimal. We focus on a slight loosening in which increased inductance values are observed, without increased resistance values, and investigate the effect of loose connectors on transmission line coupling noise under such circumstances. We find a proportional relation between coupled noise current and frequency. Moreover, we find a proportional relationship between the increased inductance value, which depends on the change in connector contact distribution, and the coupled noise current in the transmission line.

    In this paper, we introduce a new type of intentional electromagnetic interference (IEMI) fault-injection method with timing control based on leaked information. We demonstrate the fault injection attack based on the above IEMI through experiments using an Advanced Encryption Standard (AES) module implemented on a standard evaluation board (SASEBO). The experimental results indicate that generating effective faults is feasible. This paper also investigates a mechanism of faulty outputs from cryptographic modules due to the proposal method. We show the mechanism of fault occurrence through experiments using faulty ciphertexts and a sinusoidal wave injection to the specific round. The experimental results indicate that faulty outputs from cryptographic modules are caused by the overclocking to the cryptographic module.

    An IEMI-based fault injection is drawing much attention in the field of physical attacks on cryptographic devices due to its non-contact and non-invasive properties. This paper explores the relations between injection intensity and fault occurrence during IEMI-based fault injection. The basic idea is to generate a map of the effect of such fault injection for different frequencies. Through the map generated on an evaluation board, we demonstrate how an injected EM wave is propagated to the board depending on the intensity and frequency. We also demonstrate a detailed propagation of induced EM waves inside a target module (i.e., a cryptographic LSI chip) and other modules. Using the experimental map generation, we examine the condition that a transient fault available for attacks is generated in the cryptographic module. In addition, we discuss a possible countermeasure against IEMI-based fault injection.

    Values of contact resistance are one of fundamental performance factors in order to investigate contact conditions in components of electrical contacts. Therefore, the factor is applied to evaluations of mechanical contacts. However, a lot of real contacts can be considered to be parallel connections of resistance. Under this assumption, as values of contact resistances are low if there are many contact points in a contact boundary, it is considered that the values of contact resistances do not always represent conditions of real contacts. On the other hand, values of inductance change due to changes of contact distribution depending on roughness and film on a contact boundary. So, it may be possible to evaluate degradation of contact condition by measuring values of inductance on a contact boundary even if changes in values of contact resistance are not observed. In this paper, we investigate the relationship between change of contact distribution and inductance value in order to detect degradation of contact condition by focusing on changes in values of inductance on contact boundary.

    Currents on power lines contain keyboard-input information and leak the information to outside of a personal computer (PC). Especially, when a PC connects to an imbalanced three-conductor power line with a floating grounding conductor, the power line causes information leakage to increase. In previous our study, we showed the standing wave on the imbalanced power line leaks information strongly. In this paper, we find out one of the dominant factors to cause standing wave on the imbalanced power line. To this end, we propose a method to measure standing wave in detail.

    A loosened connector causes an increase in electromagnetic radiation when electric devices operate in high-frequency bands. To investigate the mechanisms generating electromagnetic radiation due to a loose contact in a connector, we estimate high-frequency circuit elements at the contact boundary of a loosened connector. On the basis of this estimation, we show the relationship between high-frequency circuit elements and the electromagnetic radiation from electric devices through experiments.

    In current campus networks, VLAN based on IEEE802.1Q is used for separating the access networks from other networks and for realizing a sophisticated access control such as guest-/home-users separation. However, using many VLANs has some problems. The first problem is the limitation of the number of VLAN IDs. The second problem is that system configuration work increases as the scale of the network becomes larger even if there are enough VLANs. In this paper, we propose a flexible access management system for campus network based on OpenFlow to solve these problems and deploy the system. We apply the proposed system to eduroam as a technology for international roaming system and evaluate access management function and the time for communication of the system. As the results, we confirm that the proposed system can realize flexible network configuration and sophisticated access control with a much simplified network management work.

    Recently, for the electrical devices operating with high frequencies, suppression of electromagnetic radiation field of high-frequency is required. With revision of EMC guidelines, the guidelines have required that the frequency bandwidth be extended from 1 GHz to 6 GHz. So, there is an urgent need to develop new test methods. We focus an effect of connectors on electromagnetic radiation when devices are interconnected with each other. In previous study, when a connector was set up using insufficient torque, the loose contact in a connector effects electromagnetic radiation field from electronic devices operating at high frequency. In this paper, in order to analyze the effect of loose contacts on electromagnetic field radiation, we show the high-frequency equivalent circuit of a loose contact connector boundary.

    Recently, for the electrical devices working at a high frequency bands, suppression of electromagnetic radiation field of high frequency band, say 1 GHz or more, is requested. We focus a connector connecting a pair of electrical devices under the high frequency band. Especially, when a device interconnects, it is difficult for a user to make the connector an ideal contact condition by using hands. In this paper, when the tightening torque of coaxial connectors is not enough, we analyze the effect of loose contacts on the electromagnetic field radiation from the transmission line.

    When a cryptographic module performs encryption or decryption, secret information which correlate to the intermediate data being processed can be leaked as side-channel information, via electromagnetic (EM) emanation. Then, the secret key may be extracted by using power analysis attacks with electromagnetic field. In previous study, it is reported that the secret information is contained in the band around clock frequency and its harmonics. It is also known that a resonance appears in the spectrum of common-mode (CM) current which causes the information leakage via the electromagnetic filed. We expect the information leakage to be larger when the resonance overlaps the clock frequency. In this study, the authors show a mechanism to determine where the resonance appears in the spectrum. In this mechanism, an information device is regarded as a resonance circuit around the clock frequency. Substrate is regarded as capacitance and attached lines are regarded as inductance respectively, the resonance frequency is determined by the capacitance and the inductance.

    When contact resistance value is low, the change of contact distribution and the number of contact points causes degradation of immunity on a transmission line with connector contact failure. In this paper, we discussed the mechanism that common mode current changes when contact distribution and the number of contact points change. The simulation results, validated by measurement, reveal that both the asymmetric contact distribution and fewer contact points increase the inductance on the connector. Using this lumped element circuit, different cable contact scenarios at the connection, i.e. the contact distribution and the number of contact points, can be simply simulated by changing the inductance term in the model.

    An underground site for school with Electronic bulletin board systems (BBS) has a lot of vandalism comments which displease other users. These comments occur by user's lack of experiences. It is important to compensate for the lack of experiences to reduce such vandalism comments. Therefore, we think that we need an education support system which cautions users when they submit a vandalism comment. Such a system needs classification method for each comment automatically. We propose a new automatic evaluation method using two types of samples and the atmosphere of BBS. This method classified each comment into a normal comment with 78.4% accuracy or into a vandalism comment with 79.8% accuracy.

    Recently, a lot of attack methods which target information leakage via electromagnetic emanation from information devices are developed, and causes real threats for information devices. Applying the EMI model to mechanism of the electromagnetic information leakage on information device, we can treat the transient current released from mounted modules as the Source; and the substrate of the device and the lines attached to the substrate as the Path and the Antenna. The authors showed a PCB and some attached lines in the information device behaves as band filter, but the mechanism is not clear. In this report the authors measure the influence of these circuit elements for frequency characteristic of the band filter focusing on inductance and capacitance of the attached lines. Our goals are giving clarified mechanism of the band filter and proposing guideline to suppress the electromagnetic information leakage from information devices.

    Electronic bulletin board systems (BBS) have become a common communication tool on the Internet. Some people who use BBS anonymously sometimes write opinions which make other people on the BBS feel bad. This is especially true as users become younger and younger and the use of BBS on the Internet and cellular phones becomes more widespread. Users don't understand how such comments can affect readers. As a result, such negative statements sometimes lead younger users to behave inappropriately on BBS. The authors have developed an assistance tool which shows users what kind of influence their statements might have on other people on the BBS. Hopefully this will make all BBS users more aware of the effects of their words on others. This should lead to a more positive atmosphere on the BBS. To improve the accuracy of evaluation for each comment, we introduce new word class to our assistant tool. Also, we propose a new automatic evaluation method using two types of samples.

    To evaluate electromagnetic noise interference on transmission line we proposed contact failure model in our previous study. However, using this model, we need full-wave simulations like finite difference time domain (FDTD) method which require large computer resource. Therefore circuit elements model which does not need full-wave simulation is needed. In this paper the authors measured inductance of the coaxial cable as a fundamental study for circuit elements model using TDR. Immunity of a coaxial cable depends on inductance of the contact failure region. When contact resistance is low inductance depends on contact distribution on the connector.

    When contact failure occurs in a connector in a coaxial High Frequency (HF) signal transmission line an electromagnetic field is radiated around the connector. The authors computed electromagnetic field in the cross-section around a connector with contact failure. The result shows the relationship between current of contact spot and electromagnetic (EM) field around the transmission line. Using this relationship, we can discuss on contact condition based on the observation of EM-field around the transmission line.

In the case of longer sentences, we treat pairs of words as samples. Using these two types of samples, the tool we developed determine the influence of the sentence.

    In this paper, we adopted the "Contact Failure Model," which explains contact failures due to faulty transmission line connectors, to measure the common-mode (CM) current, one of the factors causing noise radiation, for two independent experiments. The first experiment was carried out by gradually increasing the contact resistance; while in the second experiment, we gradually decreased the contact points. Both experiments were performed within the uplink bandwidth of CATV Internet. From the results of our experiments, we found out that the relationship between contact resistance and CM current does not depend on frequency, and by analyzing the output from a unit frequency within the uplink bandwidth of CATV, we understood that we might be able to predict the state of a faulty part causing contact failure. We also show that it is necessary for the contact failure model to keep a distribution of four or more contact points symmetrical in order to limit noise radiation.

    Electronic bulletin board system (BBS) has problems of vandalism. It is necessary for an operator to find such problems quickly when happened. For detecting such vandalism in BBS, we propose three methods to evaluate the probability based on bayesan inference. One is evaluation of the probability simply. Second employs combination of comments, and calculates its probability. Third introduces arrangement of comments as context. The result of evaluation of three methods are shown, and efficiency to find such vandalism is discussed.

    It has been known that some cryptographic tasks can be implemented by several physical handy tools such as a deck of cards and a PEZ dispenser. In this paper, we consider the use of the 15 puzzle, which is a kind of slinding puzzles, and design protocols for secure multiparty computations by applying its physical properties. In particular, we show that the 15 puzzle can securely compute any 4-variable Boolean function and any 14-variable symmetric Boolean function.

    Electronic bulletin board system (BBS) has a problem of abuse on communications. The authors had proposed a method that aids an operator to find such abuse. The method employs "Ruination Figure [RF]" which indicates influence of the BBS. The evaluation of RF is based on two types of feature extraction. One is presence of "words" which causes both positive and negative psychological effects on readers. The other is number of "responses" which is a reaction of the reader to a certain comment. Each influence of words is treated as a constant in this method and this validity is discussed. Another discussion is development of a way to detect a critical abuse from trend of the RF.

The method employs "Ruination Figure [RF]" which indicates influence of the BBS. The evaluation of RF is based on two types of feature extraction. One is presence of "words" which causes both positive and negative psychological effects on readers. The other is number of "responses" which is a reaction of the reader to a certain comment. Each influence of words is treated as a constant in this method and this validity is discussed. Another discussion is development of a way to detect a critical abuse from trend of the RF.

    Maintaining the thermal equilibrium condition in separating contacts, the contact voltage was measured and recorded under the condition of contact moving speed of 0.03μm/s that is far less than thermal flow speed, which was almost linear with respect to contact movement. The variation of contact voltage at an early state of contact separating movement was analyzed by an assumption of equivalent a-spot radius decreasing taking into account of thermal expansion of the contact material that we used was Palladium (Pd). In the process of growing dark bridge in this case, micro-discharge occurs and contributes to its growing. In the discussion on this process we gave some rational suggestions from thermal energy in sustaining the dark bridge.

    High-speed performance is one of quality which requested for remote visualization with large-scale science and technology computing. However, it is considered that transmission delay of network is a bottleneck factor. In this research, we discuss the reduction of data transmission in order to realize high-speed remote visualization. Concretely, we make clear some problems of visualization data by using TCP protocol, and as one of the solutions, we implemented RBUDP(Reliable Blast UDP) protocol which is high-speed quality and reliance quality with our remote visualization system. Moreover, we have evaluated in long-distance network environment that Tohoku University and Kyoto University are connected to Super SINET. In this report, we have expressed these contents.

    The mechanism of dark bridge formed with very slow contact separating speed was empirically shown with some discussions from the experimental results which the authors have obtained by using the cantilever system for controlling contact gap. By analyzing the obtained results, we will assume some concept of formation mechanism of dark bridge. Since the thermal effect is inevitable in the bridge formation, this will be inferred from two points; one is the a-spot change at initial state of bridge forming, and another one is the thermal expansion due to bridge current that affects the shape of bridge. This paper will show from these two points the conceptual bridge formation mechanism in case of non-melting state of contact bridge which is called here dark bridge.

    A transmission line which connects cables using connectors is influenced by noise from a connector with contact failure, and it is a cause to degrade the communication quality. The authors proposed a model of such contact resistance increase of a connector in a coaxial transmission line to simulate the noise interference into internet communication in a CATV line. Using this model, the near-field electromagnetic field around the cable which is fed HF signal was measured to estimate the noise interference into the transmission line as an electromagnetic coupling between the line and its environment. The result shows that a coaxial line which has a contact failure has a specific resonance frequency depending on its length and it is a cause of noise interference.

    The authors have developed the extremely slow separating system by using the cantilever of which length is 1m in order to investigate the contact bridge phenomena, and have found that the bridge was non-luminous when the contact separates at the extremely slow separating speed of 0.05μm/s. It has been assumed that the non-luminous bridge might be formed due to the thermal equilibrium condition achieved. At the separating speed less than 2μm/s for Pd contacts, it was estimated that the thermal equilibrium condition could be maintained around bridge, and non-luminous bridge could appear. The paper shows that, depending on the separating speed, non-luminous bridge changes to luminous one.

    The authors have developed the very slowly separating system in order to investigate the bridge phenomena in which bridge grows in the micro-gap between electrical contacts. The behavioral phenomena of contact bridge were observed by means of video image acquisition and the bridge size was measured. This experiment was the observation done under the thermal equilibrium condition. The measured data showed that the bridge size was strongly influenced by the position where the bridge was formed on the contact surface of the plane contact. When the bridge formed on the edge of the plane contact, then the bridge became larger than that formed near the center of the plane contact. This experimental result might suggest that the bridge size was strongly influenced by heat dissipation.

    From the authors' investigations on the initial instantaneous phenomena in breaking contacts, we have found the two types of bridge, i. e. one is a brightened (luminous) bridge and another one is a dark (non-luminous) one. This paper discusses on the dark bridge formed between contacts when the separation speed is very small. The following items are mentioned in this paper : a) bridge model and theory on the relationship between bridge length and diameter, b) thermal flow from bridge to its vicinity, c) deduction of a thermal equilibrium condition from the calculation of thermal flow time constant, d) experimental works, e) discussions and f) conclusions. In conclusion, we see the coincidence of the tendency of the theory and experiment carried out on the relationship between bridge diameter and length.

    For large-scaled and high precision electromagnetic field simulations with the FDTD (Finite-Difference Time-Domain) method, it is essential to utilize effectively the vector and parallel computation structure of computers. In the FDTD method, Berenger's PML (Perfectly Matched Layer) absorbing boundaries have a quite large weight, which may affect directly the performance of the whole FDTD program, hi this paper, a basic consideration of the PML programming which is adequate to the vector and parallel computation was given, and the consequent programming was shown as an example. From the evaluation results on a super-computer (NEC SX7), it was found that the speed was raised 4〜5 times for 8 parallel computations and 8 times for 16 parallel computations, respectively. Compared to the case without parallelism, a speed-up of 26 times was achieved for 16 parallel computations.

    In the contents offering service in the Internet, there is a way that contents are transferred to more than one serve and accumulated on them in advance. After accumulation, those containts are offered to a user from there. NetNews System is one of them. In this system, a rate of reading articles is low and network traffic contains unnecessary data. These unnecessary data may be caused by not reflecting on actual user's demand. To overcome this problem, we already proposed an On-Demand NetNews distribution system to solve the above problem. In this paper, we discuss an implementation method of our system and show its efficiency by the result of experiment.

    The authors observed the relationship between waveform of electromagnetic noise and change of surface for arc discharge of opening Ag-Pd electric contacts. In Ag-Pd electrodes, a continuous noise generates all over the period of arc discharge in both current polarities. The fluctuation of voltage is large in the middle part, then the noise level is high. The noise level have a tendency to decrease in the later half. The authors proposed a classification of noise waveforms and surface changes at various circuit condition, and showed the correlation between pattern of noise waveform and the change of electrode surface. Pattern of noise generation depends mainly on cathode material.

    The authors have been investigating on contact arc sustaining conditions with respect to contact opening speed and electrode temperature dependency. Contact materials are Ag and Pd which thermal conductivities are much different each other, that of Ag is much larger than that of Pd. Electrode temperature dependency has been partially known so far by the authors' experiments, especially on the Pd contacts, but not clear on the Ag contacts. More sophisticate investigations were made on the Ag contacts in this paper, and we could have some results which qualitatively showed the electrode temperature dependency on the Ag contacts.

    The authors observed the relationship between electromagnetic noise and the change of surface for arc discharge of opening Ag-Pd electrodes. In both cases of current polarity, continuous burst noise is seen in the period of arc discharge. In the case of Pd(anode)-Ag(cathode), the noise level and fluctuation of arc voltage increase in the middle of arc, and decrease in the latter half. The relationship between arc voltage waveform and the change of surface are analyzed for various current conditions. If there exist the period of the high noise level, the change of color on surfaces of both electrodes was found for Pd(anode)-Ag(cathode).

We has collected traffic data of Local IX for a long time, and analyzed the usage characteristics to verify the efficiency of Local IX. Although this kind of analysis is indispensable, the conventional analysis method may be not applicable for high-band switching network environment in future where packet dump is difficult because of the process time, also we can't measure all packet at one point. In this paper, we propose the distributed measurement and verified the validity of this method by using collected data of Local IX.

    An experimental study has been carried out for the frequency characteristics of electromagnetic noise caused from arc discharge between opening carbon and copper electrodes, and the frequency range was from 7MHz to 1GHz. The electromagnetic noise in the case of copper cathode spread over broader frequency range. In the opposite case, the noise level was larger in the low frequency range. Adding an inductance, the noise level increased in the broad band frequency range and the quasi-peak in the case of copper cathode increased more than that in the oppsite case.

    The authors observed the relationship between electromagnetic noise and trace on surface for arc discharge of opening Cu-C electrodes. In the case of C(anode)-Cu(cathode), continuous burst noise generated in the period of arc discharge. The level of noise increases at fluctuation of arc voltage in the beginning of arc, but it doesn't increase at fluctuation in the latter half of arc. Patterns of arc voltage waveform and trace on electrode surface for various circuit conditions are classified in four areas. Correlation between arc voltage and trace on electrode surface was found, as each boundary of four areas showed fine coincidence.

    Arc discharges of Silver contacts were generated under conditions of the opening velocity of 1mm/s, the voltage of 48V, and the current of 4A in air. The rate of transition to gaseous phase was determined by measured voltage waveforms between contacts. As a result of the experiments, the tendency was that the longer the electrode length, the higher the rate of transition to gaseous phase. When the electrode length changed from 2mm to 10mm, the rate of transision to gaseous phase changed from about 90% to 50%. In this paper, the voltage-waveforms of the contacts are shown, and the graph of the characteristics of the dependency of the electrode-length on the rate of transition to gaseous phase is shown. This paper suggests that the generating metallic phase in break arc might be controlled according to the structure of electrode.

    We examined the quasi-peak and the accumlated energy of electro-magnetic noise caused from arc discharge between opening carbon and copper electrodes, to study the mechanism of electro-magnetic noise caused from a commutator motor. The quasi-peak of the electro-magnetic noise in the case of carbon cathod was higher than the case of opposite polarity. The accumulated energy of electro-magnetic noise in the case of the carbon cathod increases step by step, but increases continuously when copper is cathod. The accumulated energy of electro-magnetic noise in the case of the copper cathod was seemed to increase abruptly from middle of the metalic phase to the end of the metalic phase, and increase gradually during the gaseous phase.

    From the perpective of fault management, traffic characteristics contain symptoms of faults in the network. Symptoms of faults aggregate and are manifested in the agrregate traffic characteristics generally observed by a traffic monitor. It is very difficult for a manager or an NMS to isolate the symptoms mainfested in the aggregate traffic characteristics. In this work we present a powerful technique, the divide and conquer technique, wherein symptoms are iteratively isolated from the agrregate observable.

    In Electric contacts, downsizing, high reliability and long life time have been required recently. Designs of contacts based on the elucidations of phenomena and developments of new contacts are necessary. The arc discharges decrease in performance of contacts. The arc phenomena have not been elucidated sufficiently, because the arc phenomena have many parameters such as voltage, current, contact opening velocity, and so on. In order to elucidate the contact phenomena, simultaneouse and parallel measurement under some conditions is one of the effective method. We generated the arc discharges in the air in opening Ag contacts, and arc durations and resistances were measured, and the video images of surfaces on the cathodes were simultaneousely recorded on a video-tape. In this paper, the relatinships are investigated between arc discharges and variations in colors of the surfaces on the cathodes that were analyzed by image processing software.

    The database about science information leaves something to be desired among the databases inthe computer world. Because we can search for the information about research with on1y authors or keywords in it so that the information we need is sufficient for search workers in that field. In this paper, based upon the prererties of electric contact materials, that is, from the viewpoint of material information science, we try to build the database about the electrical contacts in cases of Ishida and Sugimoto in the Takagi groupe.

    An experimantal study on the relationship between bridge and arc phenomena in breaking Ag contacts has been carried out. The transiton ratio to gaseous phase arc was controled by changing the circuit current and the ambient air pressure. The bridge voltage at the moment of rupture of bridge shifted to a lower level after a long term arc discharge which transites to the gaseous phase. The shift is not caused by the gaseous phase transition, but thermal condition of arc discharge influences. More heat energy of arc discharge or less heat radiation of electrodes increased the ratio of lower bridge voltage waveform.

    インターネットではベストエフォート型のデータ転送が行われており,転送パス上のトラフィックに関係なく静的な経路が与えられている.そのため,転送帯域に余裕のある迂回経路が存在しても,その経路を用いてトラフィックを分散させることが困難である.本研究ではデータ転送の効率化を図るため,トラフィックをリアルタイムモニタリングし,特定のユーザあるいはアプリケーションのトラフィックに対して動的に経路割り当てを行う手法を提案する.本提案手法により,動的経路を与えられるデータ転送は静的経路により転送されるクロストラフィックの影響が小さくなり,転送品質が向上する.

    An underground site for school with Electronic bulletin board systems (BBS) has a lot of vandalism comments which displease other users. These comments occur by user&#039;s lack of experiences. It is important to compensate for the lack of experiences to reduce such vandalism comments. Therefore, we think that we need an education support system which cautions users when they submit a vandalism comment. Such a system needs classification method for each comment automatically. We propose a new automatic evaluation method using two types of samples and the atmosphere of BBS. This method classified each comment into a normal comment with 78.4% accuracy or into a vandalism comment with 79.8% accuracy.

    Electronic bulletin board systems (BBS) have become a common communication tool on the Internet. Some people who use BBS anonymously sometimes write opinions which make other people on the BBS feel bad. This is especially true as users become younger and younger and the use of BBS on the Internet and cellular phones becomes more widespread. Users don&#039;t understand how such comments can affect readers. As a result, such negative statements sometimes lead younger users to behave inappropriately on BBS. The authors have developed an assistance tool which shows users what kind of influence their statements might have on other people on the BBS. Hopefully this will make all BBS users more aware of the effects of their words on others. This should lead to a more positive atmosphere on the BBS. To improve the accuracy of evaluation for each comment, we introduce new word class to our assistant tool. Also, we propose a new automatic evaluation method using two types of samples.

In the case of longer sentences, we treat pairs of words as samples. Using these two types of samples, the tool we developed determine the influence of the sentence.

    Electronic bulletin board system (BBS) has problems of vandalism. It is necessary for an operator to find such problems quickly when happened. For detecting such vandalism in BBS, we propose three methods to evaluate the probability based on bayesan inference. One is evaluation of the probability simply. Second employs combination of comments, and calculates its probability. Third introduces arrangement of comments as context. The result of evaluation of three methods are shown, and efficiency to find such vandalism is discussed.

    Electronic bulletin board system (BBS) has a problem of abuse on communications. The authors had proposed a method that aids an operator to find such abuse. The method employs &quot;Ruination Figure [RF]&quot; which indicates influence of the BBS. The evaluation of RF is based on two types of feature extraction. One is presence of &quot;words&quot; which causes both positive and negative psychological effects on readers. The other is number of &quot;responses&quot; which is a reaction of the reader to a certain comment. Each influence of words is treated as a constant in this method and this validity is discussed. Another discussion is development of a way to detect a critical abuse from trend of the RF.

    More details Close

    Tohoku University has established the campus network called TAINS88 at 1988 and Super TAINS at 1995. The successful operations and improvements of this advanced network systems deeply depend on the activity of "TAINS Users Group". "TAINS Users Group" consists of the users (staffs and students) who are interested in using TAINS to support their researches, and they are the key persons in developing the technologies related to the efficient and elegant usages of the campus network. They also reports, publish and educate their great achievements and knowledge to share them with the all members of Tohoku University, and this enables us to keep the TAINS as a high-quality network. This report focuses on the activities and the management system of the "TAINS Users Group" .

    In this research, we developed the following key technologies. As a result, in the public network where the communication paths can be changed dynamically, we achieved information theoretically secure secret key generation. Then, using the obtained secret keys, secure information communication paths can be established on a public network. Key Technology 1: We developed a technique to establish a virtual secret communication path using OpenFlow switch and Open vSwitch. Key Technology 2: We applied the ST flow protocol to the secret key sharing graph and developed a method to minimize the probability of leakage of secret keys to eavesdropper. Key Technology 3: Developed a multiparty method to share a common secret key on a public network based on Key Technology 2.

    This research project presented a new type of transient fault injection based on IEMI that causes information leakage from cryptographic modules without disrupting their operation. Moreover, the mechanism of IEMI fault injection is explained from the viewpoint of Electromagnetic Compatibility (EMC): We demonstrate the consequence of the mechanism through experiments and full wave simulations. Based on the mechanism, we proposed electric-level countermeasures against this kind of fault injection attacks.

    現在、情報セキュリティを確保するために、暗号が広く用いられている。世の中で利用されているすべての暗号は、コンピュータ無しでは動かないといっても過言ではない。例えば、公開鍵暗号方式RSAにしても、共通鍵暗号方式AESにしても、コンピュータを使わずにメッセージの暗号化を行うことは、実用上、考えられない。それに対して、本研究では、コンピュータに依存せず、もっと身近で安価で扱い易い道具を使った暗号プロトコル、すなわちコンピュータ非依存暗号の考案・開発を目的とする。本年度に行った研究によって得られた新たな知見等の成果は以下の通りである。 1.前年度において、身近な道具のひとつでスライドパズルの一種である「15パズル」に注目し、15パズルを用いることによって、多人数での安全な計算が実現できることを示した。本年度は、15パズルにより、どのような関数が安全に計算できるのか、あるいは安全に計算できないのかについて解析を行った。具体的には、以下の通りの特徴付けを得ることに成功した。 (1)4変数以下の全ての論理関数は15パズルにより安全に計算できる。 (2)15パズルにより安全に計算できない5変数の論理関数が存在する。 (3)14変数以下の全ての対称関数は15パズルにより安全に計算できる。 (4)15パズルにより安全に計算できない15変数の対称関数が存在する。 2.量子力学に基づく暗号として、量子暗号が世界中で広く研究されているが、本研究では、より身近で安価な暗号方式の開発を目指し、より古典的なニュートン力学に着目し、ニュートン力学に基づく暗号プロトコルについて検討し、剛体による秘密鍵生成法についての知見を得た。

    Along with the development of Internet, the detection of illegal access is becoming a major issue. A guarantee of a secure utilization of Internet is very vital for developers. Therefore, the technology of preventing Internet from intrusion and denial of service attacks is in great demand. The typical cases of illegal access are as follows: 1- Penetrating and gaining privileges by illegal measures, then stealing classified information, destroying the system or using it as a stepping-stone for further attacks. 2- Forging the source IP address and sending a large amount of useless traffic. 3- Generating incomplete connections far beyond design limitations of the targeted WWW and DNS server to force it to no longer function. In order to prevent illegal access, the detection of signs of an oncoming attack can be effective. By so doing, we can protect our network system beforehand. In this research, we propose an organization-defense style security system by using the detection of omens (signs) of illegal access. This system detects various network scans that intend to find out vulnerability of remote network nodes. We implemented the system and evaluated its performance on an operating network. Experimental results show the effectiveness of our proposed system.

    The purpose of the project is contro1 of electromagnetic noise generated from small electric appliances. A real-time parallel measurement system was developed for synthetic analysis of the phenomena of discahrge and noise generation of electric contacts. A progressive idea in this experiment is analysis of relationship of noise generation to the trace of arc discharge on the electrode surface. The conducting noise on the power line was measured for breaking contacts of two types. One is a Cu-C moving electric contact which simulates a pair of a commutator (Cu) and a brush (C) in a commutator motor in a small electric appliance, and the other is a Ag-Pd contact as a general heterogeneous electric contact. Waveforms of noise, voltage and current across the electric contact, and surface photograph of the electrode are measured in a simultaneous parallel way to analyze APD (amplitude probability distribution) of noise and the correlation in discharge phenomena. The phenomena of noise generation is classified into two patterns which are sporadic and continuous burst noise types depending on material condition. When a sporadic burst noise occurs, the trace of discharge on the electrode surface is formed in the noise duration, and we proposed that noise generation would be controllable by controlling formation of the discharge trace. When continuous noise occurs, the duration of large noise has correlation with the area or the discharge trace on the cathode surface for C-Cu, or the area of different color on the anode for Ag-Pd, respectively, and we proposed that arc duration should be controlled. An experiment showed that the noise duration could be reduced, by reducing the contact surface of electrodes for the sporadic burst noise, or by making the electrode thick in the case of the continuous burst noise. The result shows that the proposal that design of electrode shape is important in control of noise generation.

    Expansion in scale and speed are the most important features of Internet. Establishing an effective way for fault management becomes the main topic for this computer networks. In this research, we proposed a new system for real-time fault detecting in large scale computer network. We first constructed a traffic monitoring system for collecting the error packets from network traffic flow. Then, we proposed a new algorithm, called Dynamic Symptom Isolation Algorithm, to detect the network fault packets in an effective way, in which filtering technique is applied to suppress the detected error symptom, so that the small fault existing behind the large number faults in the network could be found thoroughly. Our experiments showed that the new system's performance is as twice as the conventional system for detecting faults symptoms in large network environment..

    To realize integrated electromechanical devices with higher performance, instead of conventional electromagnetic actuators, piezoelectric actuators consisting of single crystals with a polarization-inverted layer have been studied for application with new electromechanical devices. Bending actuators for miniaturization and electrical drive methods for quick response were proposed, and contact phenomena were examined experimentally for high reliability. The following results were obtained. 1. The formation of a LiNbO_3 polarization-inverted layer and the fabrication technique of the actuators were improved. A power-saving precision actuator with no hysteresis and no creep was developed. 2. The defect of electrical contact due to oxidation or contamination in the atmosphere containing silicone was investigated. The effect on an electrode surface membrane and electric resistance of a heat treatment and a surrounding area atmosphere was studied. Moreover, the change of resistance due to surface impurities on the electrode caused by repeated contact was examined. 3. To design new electromechanical actuators using a piezoelectric crystal, a computer simulation technique using a three-dimensional finite element method was improved. The results of the numerical analysis for displacement, resonant frequency, and electromechanical coupling coefficient were experimentally confirmed. 4. A piezoelectric actuator with a integrated displacement sensor was proposed and examined to evaluate electrical contact phenomena such as an insulation destruction voltage and a locking phenomena. 5. A servo accelerometer using a LiNbO_3 bending actuator was proposed and its potential was experimentally confirmed as a highly sensitive sensor in a frequency range of less than 1Hz. 6. A proximity sensor utilizing an evanescent acoustic field formed by the LiNbO_3 bending vibrator with a polarization-inverted layer is proposed. It was demonstrated that when an object approached the surface of the vibrator, resonance frequency of the bending vibrator decreased sharply.

    This tesearch developed a spoken word recognition system which used phoneme duration information estimated from the speaking rate of an input speech. In this research, the speaking rate is assumed to be reflected to the average vowel length. The acoustic processor transforms the input speech into a similarity matrix using the modified LVQ2. The average vowel length is computed from the preliminary recognition result. The duration of each phoneme in each word template is estimated from the average length of vowels in the input speech. By taking into account the estimated phoneme duration, the spoken word recognition experiments were carried out using the DTW.The word recognition score was 97.3% for the 212 word vocabulary uttered by 5 male speakers (test set). The phoneme duration information is collected from the 212 word vocabulary uttered by another 5 male and 10 female speakers (training set). The hybrid combination of the prceiding phoneme dependent estimation and the follwoing phoneme dependent estimation gave the best performance. The above-mentioned method was extended to phoneme recognition. The phoneme accuracy increased from 71.8% to 86.3% for phonemes in the 212 word vocabulary uttered by 5 male speakers (test set).

    1. The present system converting data into frequency is named as "Oscillation Modulating Transducer", which means, except for the present near distance measurement, this system is useful for the other data or sensor outputs to be converted into frequency. 2. For Near Distance Measurement Method, a prototype was tested and made it clear that the method may be used as in practical. The accuracy was tested and made it clear that it can go into more accurate than 10^<-4> by taking the values of DELTAf/fo (fo : free oscillation frequency, DELTAf : shift frequency dependent of distance to be measured). The maximum distance is limited by the lens system rather than the laser coherency. 3. Development of the present distance measurement principle to another application was made. A concrete non-battery sensor for snowfall, which the corporation of Tohoku Electric Co. Ltd., and made it clear that the system may be well used in practical. 4. Future works will be done by extending this system called "Oscillation Modulating Transducer" to the other sensors.

    More details Close

    This project aims at development of measurement of actual contact performance and condition of metal contact surface, and its novelty is in implementation based on relationship of actual contact condition to high-frequency signal transfer characteristics. The intended contact performance is measurement of actual contact area and condition which are affected by roughness and contamination of metal surface. Measurement of high-frequency signal transfer characteristics makes it possible to observe minute contact degradation which cannot be observed by electrical resistance, and measurement of inductance achieves high-sensitivity measurement of contact condition.
