Remarks on Weierstrass semigroups of a Pair of Points Whose First Non-gaps Are Three
Get PDFapplication/pdfWe determine the Weierstrass semigroup of a pair (P, Q) of points on a curve of genus g ≧ 4 such that the Weierstrass semigroups of P and Q are the same one, which is a symmetric or quasi-symmetric semigroup whose first non-gap is three.departmental bulletin pape
Personal Authentication with Keystroke Timing Patterns on Self-Organizing Maps
Get PDFapplication/pdfIn this article, we propose the method of personal authentication with Keystroke Timing Patterns on Self-Organizing Maps (SOM) for Web based Application. We tested the system ability to measure FRR (False Reject Rate) and FAR (False Accept Rate) on the maps which learning with 40 input-vector. For result of this ability test, our system keep FAR 54.3% when FRR 31.87%. Thus, it seems that our method is available for personal authentication.departmental bulletin pape
A Self-Orientation Method in Road Driving -Discriminating Analysis for Straight or Curved Paths-
Get PDFapplication/pdfTo support the operation of automobile, a self-orientation method in road driving was examined. In this paper, emphasis was put to judges whether it is a curved path or not by analyzing image of on board camera. It was clarified by computer simulation that the discriminating analysis was possible, by applying image recognition algorithm following to projection on road plane.departmental bulletin pape
Distributed Database Management System for Clinical Cases with Servlet-Servlet Connection
Get PDFapplication/pdfShareing clinical cases are useful for medical field. We suggest a distributed database management system for clinical cases with Java Servlet. In this system, case informations were put two or more servers, and case index information using case searching were put on all servers. Communication between each servers were used Servlet-Servlet Connection. With this method, the system could handle various style of formatted data and system could be more extensive and more reliable.departmental bulletin pape
The Computer Simulation of the Resonant Motion between Two Lorenz Chaos Water Wheel by the Higher Order Linear Coupling Using Parallel Computation
Get PDFapplication/pdfThe first, famous chaos system discovered by Lorenz corresponds exactly to aw ater wheel mechanical device. This simple device proves of surprisingly complicated behavior. Calculations were performed for the linear coupling with first and secondary coupling coefficient between the two Lorenz chaos water wheel systems using the parallel computer. The individual water wheel is like a slice through the cylinder. The system is driven steadily by water dissipate energy, in which buckets lose water. In individual system, the long-time behavior depends on how hard the driving energy is. Water pours in from the top at as teady rate. If the flow of water in the water wheel is slow, the top bucket never fills up to overcome friction, and the wheel never starts turning. If the flow is faster, the weight of the top bucket sets the wheel in motion. The water wheel can set into a rotation that continues at a steady rate. But if the flow is faster still, the spin can become chaotic, because of nonlinear effects into the system. As buckets pass under the flowing water, how many they fill depends on the speed of spin. If the wheel is spinning rapidly, the buckets have little time to fill up. Also, if the wheel is spinning rapidly, buckets can start up the other side before they have time to empty. As are sult, heavy buckets on the side moving. Upward can cause the spin to slow down and then reverse. In individual system, the spin can reverse itself many time, never settling down to as teady rate and never repeating itself in any predictable pattern. The parallel computer simulation for combination of the only first coupling coefficient between the two chaos water wheel was suggested that the rotational motions were instantly synchronized with increasing the value of the first coupling coefficient. It was confirmed that the chaotic motion of the two water wheel generated the turbulence, when it is considered to the secondary combination between the two water wheel, and it changed to the other chaotic phase.departmental bulletin pape
Toward a Clinical Sociology Based on Bourdieu's Sociological Theory -The Possibility and Necessity of Soeiology in Well-being Society-
Get PDFapplication/pdfIn the near future, Japan would become the society of mass longevity. That requires us to reflect the meaning and value of sociology, and to see what it can be and what it should do for Japanese society. Today, thus, the "clinical sociology" gets much attention from both sociologist and people in society. In this paper, to redefine a clinical sociology, to re-consider the possibility and necessity of sociology itself in well-being society (in welfare state), I suggest that Bourideu's sociological theory and his sociological-social practice, the practice of reflexivity based on his sociological theory of knowledge, should be much useful.departmental bulletin pape
Sputtered Species from Cu and YBa2Cu3Ox Targets Studied by Quadrupole Mass Spectrometer
Get PDFapplication/pdfIn order to clarify the sputtered species from a target, a quadrupole mass spectrometer system evacuated differentially was developed. A copper metal target was sputtered to test this system. The system detected 63Cu and 65Cu of copper isotopes in mass spectra. The observed ratio of 63Cu and 65Cu was 7:3, which was close to the value of 69:31, the natural abundance of 63Cu and 65Cu. This result showed that the system could detect Cu atoms sputtered from Cu metal target. In the case of an YBa2Cu3Ox oxide target, the system detected Y, Ba and Cu signals. However, the observed signals of Ba or Cu isotopes were almost the same intensities, contrary to the expected values of the natural abundance of Ba or Cu. The observed signal was not due to sputtered species from the oxide target.departmental bulletin pape
A New Approach to the RKKY Interaction
Get PDFapplication/pdfWe propose a new method for the RKKY interaction, in which an expression derived by Nolting et al. (1997) is combined with the single-site approximation for the s-f model by Takahashi et al. (1996)departmental bulletin pape
The Results of the WUHAN OPERATION (1938-1939) (II)
Get PDFapplication/pdfThe Wuhan operation had started before Cherepanov arrived. In this operation, the Japanese army adopted a "ram" tactic, possessing insufficinet numerical strength for such a country as China, but enjoying tremendous superiority in armament and equipment. In the course of the offensive against Wuhan, the Japanese army concentrated artillery, tanks, and air forces on the main operational section of the front, broke through Chinese defences, and drove a wedge deep into Chinese territory. The strategic plan of the Japanese army in the war against China was described as quick war and quick victory: it envisaged the capture of Shanghai within a week, North China in am onth and all of China in three months. The Chinese command's strategic plan was geared to a long-term war.departmental bulletin pape
Combustion Characteristics of Stratified Charge Engine with Pilot Flame Ignition
Get PDFapplication/pdfA stratified charge engine with pilot flame ignition which has high ignition energy, large flame contact area and long duration of spark, is examined using a mode] combustion chamber. As a result, it was found that the pilot flame ignition system had better ignitability and combustion performance in the lean mixture range than the spark ignition system.departmental bulletin pape
