Digits of the hand are serving an important role in our daily life. So we set the development of power-assist glove for elderly people with a weak grip as our goal of this study. In doing the power-assist, we use the electromyography (EMG) to measure the degree of muscular power. Accordingly, only people who can detect the muscle electric potential can use our power-assist glove. Three men and two women participate in this study. Two men who are coeval do the experiment of cause-and-effect relation between tiredness and EMG. One man and two women (age 15, 48, 76) do the experiment of cause-and-effect relation between age and EMG. Experimental result shows that EMG varies among different individuals, EMG is increased by tiredness, and there are no correlation between age and EMG. That means homeostatic update of threshold value on control of power-assist glove is absolutely imperative. Besides, we create a simple experimental arrangement and succeed at control by master-slave control and a develop prototype of power-assist glove.

In recent years, sophisticated and low-impact medical equipments are developed. However those devices increase operator's burden. And using those devices renders the operator at increased risk of acquiring an infection by the damage of surgical gloves. So the author decides the non-contact type manipulating system can circumvent those difficulties. In this paper, the author considers a method of hand shape estimation constitute a system. The author shows the utility of the inverse kinematics using limitation of living structure for shape estimation, and the usefulness of the stereo view for acquisition of coordinate. The result shows the system functions well in the center of the working area, but not functions properly near the boundary of working area. These reasons are the error of distance measurement and inflexible judgment condition near the boundary of working area.

This paper proposes an automatic human posture acquisition technique by a robot. Decrease of working population will be a viral problem in our society. Escaping from the work in danger is also important for a human being to raise QOL. To solve all theses issues, it may be quite useful to realize a robot which works in place of a human. Based on this background, our research aims at making a technique for a robot to acquire various human postures/motions automatically. In this paper, a technique is presented for obtaining human postures automatically by employing a human skeleton model and a stereo camera system. Performance of the technique is shown experimentally.

The plain X-ray photography has following shortcomings : 1. Lack of the information about the position in front-back direction. 2. Overlap of different objects in front back direction. 3. The penumbra due to the finite size of X-ray source.The relationship between the broadening of penumbra and the position of film is the key to resolve these problems. However, the reverse problem of determing the original images from the observed blurred images suffers from the instability with non-local inverse matrix. We discuss methods to overcome the instability. Finally, we consider the application of fuzzy concept to improve the readability of X-ray images.

We analyzed lead concentrations in bones from both genders of Japanese merchants (including rohnin ; masterless samurai) and farmer classes, and compared the findings with those of the samurai class in the Edo period (1603-1867) to clarify gender and hierarchical (or occupational) differences in lead exposure during the Japanese feudal age. Merchant class females had significantly higher lead exposure (90.8μg Pb/g dry bone ; n=20) than males of the same class (39.9μgPb/g dry bone ; n=31) (p<0.01), indicating a remarkable gender difference in the urban population. In contrast to these high concentrations, males and females of the farmer class living in agricultural (or semi-rural) areas had significantly lower exposure (total mean value ; 9.2 μg Pb/g dry bone ; n=4) than both gender of the merchant class (p<0.001), and the gender difference was not seen in this class.

Rough set theory was proposed by Z.Pawlak in 1982. This theory can mine knowledge of decision rules from a database, a web base, a set and so on. The decision rules are used for data analysis as well. Then we can reason for an unknown object using the decision rules. In this paper, we apply the rough set theory to analysis of time series data. We acquire knowledge based on one-minute chart fluctuations.

The objective of economic analysis is to interpret the past, present or future economic state by analyzing economical data. In many cases an economic analysis is pursued based on the time-series data or is analyzed the structure of the target system by multivariate data. Time-series analysis and regression model are central tools to analyze economics data. Nevertheless, economic systems are a complex system resulted from human behaviors and related to many factors. When the system includes much uncertainty such as ones of human behaviors, it is better to employ methodologies of a fuzzy system in the analysis. In this paper, we analyze a Tick data by possibilistic AR model.

Author investigated the periodicity of the dates of vertigo onset. The subjects were 1600 patients (428 male ; 1172 female), with vertigo, sudden deafness related vertigo, Meniere's disease, who consulted author's clinic between April 1, 2005 and April 30, 2010 (1849 days). The dates of vertigo appearance or exacerbation were surveyed from these patients, and the periodicity of the date of vertigo onset was analyzed. <Method> The time series from day 1 to day 1849 was divided by X (X=1 to 28) day. The onset days of the vertigo were counted in every each period that was divided by X. And new time series-es of 28 categories, depended on X, were obtained. Auto-correlation coefficients of every new time series-es were calculated. Data smoothing by the moving average method was performed to each auto-correlation coefficients to make tendencies of the changes clear. <Result> At least three types of periods were detected. The periodicities of them were 690±96 days, 328±133 days 126±46 days, respectively. <Conclusion> It was thought that there were periodicity of about 2 years, 11 months, and 4 months on a vertigo onset days.

One of most expected material for hydrogen storage is Metal-Organic Frameworks (MOFs) which can hold up to 7 % hydrogen by weight using intermolecular interaction, already exceeded the US Department of Energy's target of 6 %. However this can only be achieved at very low temperature of -200 degrees C and hydrogen-storage capacity is reduced to around 1 % at ambient temperatures. So many efforts have been continueing to increase the capacity at realistic temperature but it seems not easy. This paper describes CO_2 and H_2 inclusion phenomenon of calix[4]arene with various functional groups. Thereby we have investigated their possibilities for practical use such as gas separation, transportation and storage including hydrogen storage for FC vehicles.

Visually important image features often disappear when color images are converted to grayscale. To solve this problem, A.A. Gooch et al. has proposed the salience-preserving color removal method called "Color2Gray. " But Color2Gray suffer from the disadvantage of heavy computational cost. So, G. Tanaka et. Al. devised new fast method for computational cost reduction. However, this method of computational cost reduction is still insufficient. In this article, we introduced faster salience-preserving color removal method. Finally, the effectiveness of our proposed method is verified by some experiments.

Pulsed magnetic stimulation (MS) uses pulsed magnetic fields to induce electric fields (electromagnetic induction) in tissues for therapeutic purpose and is a technique that does not require surgery or external electrodes. In the previous study, our group performed in vitro experiment to examine the effects of pulsed MS on human chronic myelogenous leukemic cells. The present study demonstrated the finite element method-based numerical estimation for pulsed MS-induced magnetic and current distributions in a body in order to examine the possibility for therapeutic application of MS. The maximum induced eddy currents were 0-83.55 A/m^2 in the body and 0-25.35 A/m^2 at the pelvis by 100 mm circular coil with 1.25 T pulse magnetic field. These results were comparable with those values of cellular experiments (0 28.6-38.1 A/m^2), however, optimized coil characterization and further numerical calculation are necessary to prevent possible adverse effects (pains and muscle stimulation) induced by MS.

Personal authentication becomes ubiquitous because the number of Internet users is increasing. People are used to input their name and password but a password-based authentication is vulnerable because it is easy to leak a password. For this reason, people will need a more secure authentication method. In this article, we propose a gesture authentication method, which is one of biometrics authentication. It uses self-organizing maps (SOM) to authenticate users because it can learn each gesture characteristics and secular change. We experimented with a game controller which mounts acceleration sensors and evaluated an availability of multi-maps gesture authentication. As the result, our method obtains over 90% accuracy but map size or the number of subjects in a map seems to be ill-fitted. We will verify the accuracy of authentication under other conditions of varied sizes of maps and varied numbers of subjects.

It is well known that fuzzy mapping plays an important and fundamental role in fuzzy analysis. In this paper, we attempt to determine extensive classes of these fuzzy mappings that are represented by their Taylor expansion. We have first obtained that the continuous function f (x) can transform a fuzzy mapping f (u) using the extension principle. And we discuss some properties of the series of fuzzy numbers. From these properties we have seen that f (u) has the property of being analytic for the analytic function f (x). Finally as an application, we give a sufficient condition for convergence of a fuzzy alternating series.

When a person is given a question, she/he shifts the gaze to another position with vacant eyes. We can obtain ERP (Eye Fixation Related Potential) with averaging EEGs at offset ofsaccades. In this study, we measured EFRP during thinking. 10 participants faced to a stripe pattern. They were assigned a mental arithmetic task (30 questions), The participant moved eyes on the stripe pattern. Eye movements and EEGs (Oz, Pz, Cz) were recorded. When a participant started to think about a question, involuntary saccades occurred. EEGs associated with offset ofsaccades were averaged to obtain EFRP. The positive component with latency of about 80ms of EFRP appeared from all participants in the eye movement task. The amplitude in calculation was significantly smaller than those in the eye movement task. Some participants showed alpha waves after eyes shifted. Those resulst showed the visual function declined, while a person was thinking about something.

Toshiba corporation made a successful in creating a medical machinery named Nemu-rhythm which can measure the quality of sleep conveniently from the change of the wrist pulsation and activity at night. The first point to be discussed is that the quality of sleep is not easy to know simply because that it is highly susceptible to the influence of Sustainable mechanism and Circadian rhythm. Despite the difficulty, we have had practiced Polysomnography that is very inconvenient and the examination tasks the patient's mentality to investigate the quality of sleep. Now we anticipate Nemu-rhythm will solve these problems. Added to these problems, numerous attempts have been made by scholars to demonstrate the relationship of alcohol intake and insomnia, Hyperlipemia and insomnia, etc... however we have to say these problems are still in controversy. As we got some intrigue results about these problems this time, we are going to do presentation about system of this machine and also the relationship of sleep and other illness in meeting place.

Radiation dose by neutrons produced by proton and heavy ion induced nuclear reactions around tumor is essential for dose assessment in proton and heavy ion radiotherapies. Double differential cross section (DDX) of neutron production is one of important physical quantities for dose estimation by radiation transport codes. Some experimental data of neutron production DDXs have been reported above 5 MeV of neutron energy for heavy ion incident reactions. Neutron production DDX for carbon ion incidence on carbon target was measured at the Heavy Ion Medical Accelerator in Chiba (HIMAC) including low neutron energy region for validation of radiation transport codes. Incident carbon energy was 290 MeV/u. NE213 liquid organic scintillators were deployed as neutron detectors and placed at IS, 30° 45°, 60°, 75° and 90°. Neutron energies were determined by the time-of-flight methods. Neutron detection efficiency was calculated by the SCINFUL-QMD code. The obtained minimum neutron energy was about 2.8 MeV. The experimental data of neutron production DDX was compared with that by one of radiation transport codes, PHITS.

It is important to diagnose developmental dislocation of the hip (DDH) by X-ray images. The aim of this study was to construct a diagnostic support system for DDH based on clinical findings obtained from the X-ray images of 154 female infants with confirmed diagnoses made by orthopedists. The Min-Max method of nonlinear analysis was applied to construct the diagnostic support system based on the measurement of four items in X-ray images : the outward displacement rate, upward displacement rate, OE angle, and a angle. This system was then applied to the data, we obtained good results that matched the confirmed diagnoses of orthopedists with an accuracy of 85.9%.

This document is a summary of literatures [12, 17, 18, 19, 22, 23]. We have a highly interest in near-infrared spectroscopy (NIRS) method or optical topography (OT) of multiple measurements with following five advantages : (i) completely non-invasive measurements with a brief start-up, (ii) a bedside equipment with silent operation and continuous monitoring, (iii) hemodynamic observation in the cerebral association cortices, (iv) high flexibility in an experimental design because of tolerance for artifacts, and (v) low running costs without addition of supplies. We are planning to measure cerebral blood volume (CBV) change in the auditory association cortices, which are closely related to linguistic ability, because many neuroimaging studies with spatial resolution have commonly reported the left dominance of cerebral blood flow (CBF) and/or blood oxygenation level dependent (BOLD) contrast during language-oriented tasks or even a simple listening to speeches. Various synthesized speeches may reveal what structure in waveforms plays an essential role in the neurophysiological speech recognition by means of a semi-quantified index of lateral oxygenation.

The purpose of our study is to evaluate the quality of synthesized speeches by measuring the mismatch negativity (MMN) of the event-related potentials (ERPs). The proposed synthesis has required the superposition of six-channel sinusoidal interpolation between the extremal data of the filtered waveform, in which each passband had one octave, belonging to the total bandwidth of 80 to 5,120 Hz. Subjects were presented with a repetitive stimulus of an original syllable /ki/, randomly replaced at a 14.3 % probability by a synthesized one. No MMN responses were observed in the task, suggesting that the extremal data played a key role in the synthesis of the phonetic equivalence of the acoustic structure. When employing discontinuous and/or distorted interpolation, MMNs were evoked by increase of power in higher spectral channels, also enhancing the hypothesis of a simple extremal detector in the early-stage of the auditory system.

This paper proposes a method to detect obstacles from a video taken by a moving camera mounted on a vehicle by background subtraction. The background subtraction is often used to detect moving objects when camera is static. But according to the characteristics of a road, we can also employ Gaussian mixture model to detect all objects (either static or moving objects) on the road in the case of moving camera. After background subtraction, we get a foreground image which includes all objects on the road, buildings outside the road, shadows and road marks. Our goal is to detect obstacles on the road, so next we use Hough transform to detect road area to delete buildings ; we use NCC to delete shadows; and we use triplets to detect a zebra crossing and delete it. In our experiments, it is shown that proposed method is able to detect obstacles such as vehicles and pedestrians on the road.

As the growth of Business Process Management (BPM) market, process customization based on customer requirement is arising for the competitive advantage of business organizations. When there are numerous of demand for customization, it causes a great number of business process model variations. The existence of numerous process variations leads to process redundancy and process underutilization, which can effect to business performance. Thus, there is a need to create a process reference model to identify and eliminate duplicate process information. This paper introduces a new approach to generate business process reference model from a process repository using Genetic Algorithm (GA). The automated creation of the reference model is basically executed using business process structure properties and the proximity of activities. In the end of this paper, we show the experiment result of our proposed method. It is believed that this process reference model can assist a novice process designer in creating new process based on existing processes.

This paper applies the fuzzy cluster analysis to six international stock markets (i.e., France, Germany, the U.S., Canada, Japan, and China). We analyze the similarity values calculated from the monthly stock returns, using both Zadeh's and Ward's clustering methods. These two methods induce different partition trees. Both the Minkowski distance and cophenetic correlation coefficient choose Zadeh's method over Ward's method. The optimal partition tree and the associated optimal number of clusters suggest (1) the similarity of European countries, (2) the institutional regularity of the Chinese stock market, and (3) the strong influence of the U.S. These implications are consistent with standard economic theory, and are preserved under the addition of three countries (i.e., the U.K., Mexico, and South Korea).

This paper presents a web application which improves the usability of a fuzzy retrieval system for purchasing cars. The aim of this system is to support such persons who are not good with machines or cars when they select a car. Unspecific conditions are expressed by the fuzzy set, and the level matching conditions are expressed by the grade values. To use this more practically, a GUI form with selection menus is developed. In addition, employing the self-organizing maps performs clustering and visualization of the result (obtained from the fuzzy retrieval system) in order to improve the accuracy of decision making.

To develop truly autonomous and intelligent mobile robots, the developmental approach is indispensable. Considering the development of human beings, internal rewards which are related to the instinctive desire, motivation, curiosity, novelty, etc., are important factors contributing to the development. For the robots, there are several studies in which curiosity and novelty are used to promote the progress of learning. In this paper we propose an internal reward called "appetitive reword" and a function to control it, for the robots which have to acquire an action policy for a mission to "survive and perform a instructed task effectively". The "appetitive reword" is inspired by "appetite" of human beings, which is known to be well regulated by a mechanism between the digestive tract and the brain. By using an example of a security guard robot, we show the effectiveness of the proposed reward.

Biclustering is an important analysis method on gene expression data. However, few biclustering methods provided a query-based approach for biologists to search the biclusters which contain a certain gene of interest. In this paper, we proposed a generalized fuzzy-based approach, namely Weighted Fuzzy-based Maximum Similarity Biclustering (WF-MSB), for extracting a query-based bicluster based on the user-defined reference gene. A fuzzy-based similarity measurement and condition weighting approach are used to extract significant most similar and most dissimilar biclusters to the reference gene in expression levels. The proposed WF-MSB method was evaluated in comparison with MSBE on a real yeast microarray data, and the results show that WF-MSB can effectively find the biclusters with significant GO-basedfunctional meanings.

A classifier to classify the normal samples and the samples with hepatoma based on the sample's SELDI-TOF mass spectra is designed in this paper. A modified genetic algorithm (GA) called gene-weighted GA (GWGA) is proposed to design the classifier based on the SELDI-TOF mass spectra. To reduce the computation efforts, an approach dividing the measurement intensities within different range of m/z values into several data sectors and finding the peak intensity within each data sector is proposed. The peak intensity at each data sector is taken as features for classification. The proposed GWGA aims to select the features and minimize the number of selected features while maximize the classification accuracy. Within the GWGA, the support vector machine(SVM) is utilized as the classification approach based on the features evolved in the chromosome of GWGA.

In this paper, instead of the time-invariant state-space representation in the consequent of the T-S fuzzy model, tim,e-varying system is considered in order to deal with the reconstruction error between the real system to be controlled and its T-S model, and fuzzy approximator is employed to cope with unknown functions involved in the model. As a result, it reaches an adaptive controller that has two parts: one is obtained by solving certain linear matrix inequalities (LMIs) (fixed part) and another one is acquired by the fuzzy approximator in which the related parameters are tuned by adaptive law (variable part). The proposed controller can guarantee the closed-loop system to be asymptotically stable.

Walking rehabilitation machines have drawn great attentions with more and more people suffering from walking disabilities in an aging society. However, most of the developed walking rehabilitation machines aim at enhancing muscle strength, neglecting the recovery of the neural system. 58% of walking disabilities are caused by problems in the neural system. Therefore, we propose a rehabilitation system which includes both muscle strength enhancement by a walking rehabilitation machine and neurological rehabilitation by imaginary walking. In this paper we compared the activation in motor area of the brain during real walking and imaginary walking by means of fNIRS (functional Near-InfraRed Spectroscopy). Two subjects participated in the experiment. During imaginary walking, the subjects were instructed to imagine that they were walking with the same pace to a person in the video being shown to the subjects. As a result, the concentration of oxygenated hemoglobin in motor area during imaginary walking was higher than that during real walking in both of the subjects. This was because that it was not necessary to pay attention to the movements of the legs and feet during normal walking on the plain road without any obstacles, while movement planning was required when the subjects imagined their walking in the same way to another person. The experiment result indicated that it is possible to quicken walking rehabilitation by imaginary walking.

The effective extraction of the information from web pages is the prerequisite to the full use of the web resources. We proposed a new method for information extraction from web pages based on the length of the nodes in the DOM tree. We will firstly represent the web page into a DOM tree using the html tags, then the content node of the tree will be identified according to the longest text node, and at last we will distinguish the body of the text block and extract the main content of the web page using the continuity of the structure of the main text content in the DOM tree. The experiment testified the accuracy and efficiency of this method.

In solving optimization problems, the most important thing is how effectively explore the solution space without being trapped by local minima. We have been developing optimization techniques which are based on Lagrangian method. In these methods, each constraint has weight, and all weights are updated in each step. This cause the ability of escaping from local minima. However we also found that updating the weights has undesirable side effect. In this paper we proposed a new method in which update of weights is done only in restricted steps. We apply this method to Software-MCU assignment problems and the experimental results show that we can improve the efficiency of the Lagrangian method further.

We measured proton-production double differential cross sections (DDX) using 290 MeV/u oxygen beams on carbon, aluminum and copper targets at forward angles. The proton energies were measured with the spectrometer which consisted of GSO(Ce) crystals and plastic scintillators. The measured DDX were compared with the simulated ones using the PHITS code. The simulation results generally agreed with the measured DDX. The experimental data on DDX will be useful as the benchmark of existing simulation codes and for the future improvements.

It is known that the slowly-varying (4-16Hz) amplitude envelope plays an important role in transmitting speech information. According to the forward masking effect, the threshold of hearing, yet, mil be enlarged by sound pressure of precedent stimuli, suggesting short-term unperceiv able periods in speech waveforms. The goal of this study is, thus, to show the localization of speech carriers over time. Conflict between subjective scores and quantization errors was observed when all the diminished parts in amplitude were changed to 80% of the precedent envelope maxima. Although quantization error was computationally 104%, which was much larger than the allowance (>20-40%), the noise was subjectively inaudible. The results are interpreted as evidence that the envelope maxima and minima in the repeated structure correspond to the key information and the short-term connection with less perception, respectively. We estimate that the inaudible structure amounts to 67.4% at a bandwidth of 80-5,120Hz.

We proposed new basic theory and methods for quantum neurons and neuro-qunatum-circuits based on functional path integral of quantum theory. And then we concretely calculated probability amplitudes for quantum circuit and slit which have interferences and tunnel effects. We give operator expressions of switches and their circuits, and the diagrams of those systems correspond to potentials of Hamiltonian. Finally, we found that AND-circuit is represented by second order of perturbation, and OR-circuit looks upon as two particles scattering system. We showed it is useful to design and to make tests for new quantum system and computers.

An automatic diagnosis for patellar tracking mechanism of knees is developed in this paper. Because computer has the property of accuracy, high speed, and low cost, the developed method of research for dynamic automatic diagnosis substitute for the conventional static diagnosis. In the experiment, each volunteer have eight different angles of knees image in axial and sagittal direction respectively. To measure kinematic parameters, three inclination angles are computed from eight landmarks identified from the patellar and femur in the axial MR images. This research could help doctor to diagnose function of patella in the clinical experiment.
