This paper describes characteristics of human speed sensation for flying-ball pictures. Flying-ball is arranged with a certain density, and its velocity is constant. First, we arranged flying-ball regularly and measured a relationship between density, velocity, and sensation of speed. As a result, we clarified that sensation of speed relates to the number offlying-balls which pass through on display...
We have tried to detect changes of affects by measuring accelerated plethysmogram. We gave 9 kinds of mental stimuli to 22 subjects and measured their accelerated plethysinograms. We chose the power spectrum of a-wave intervals of accelerated plethysmogram as an index to detect changes of affects. The accumulated powers in a low frequency region measured in many kinds of stimuli were significantly...
We propose a communication aid that uses sympathetic skin response (SSR) as the input indicator for a device that will assist the disabled. To this end, we used subjects who engaged in character selection while listening to four sounds [white noise, J-POP (Vocal), J-POP (Less-Vocal), and Classical], in order to clarify the influence of sound. Although sound had a weak influence on the target kana,...
The human visual system with high-level recognition abilities is able to efficiently and accurately identify an object based on object parts, which is defined as the human visual interpolation ability. In the present study, a letter recognition experiment was designed to evaluate the human visual interpolation ability for partially erased objects. Six subjects were asked to identify partially erased...
We examined how the sensation of touch influenced the perception of sound and its effect on sensibility. This was assessed in subjects listening to music in conjunction with experiencing the vibrations produced by a low-tone rhythm musical instrument such as a base. Physically experiencing the vibrations produced by the base appeared to increase the clarity of the base sound and that the sound source...
This paper proposes a novel system to create the moving picture based on music physical parameters and its Kansei factors. The moving picture is created to have equivalent Kansei with the music. The Kansei factors we derived are as follows: rhythmical sensation, mellow sensation, brilliant sensation, and powerful sensation. The system was evaluated by using fireworks picture. As a result, the proposed...
One of the goals of Intelligent Transport Systems (ITSs) is to reduce traffic accidents and enhance safety. However, plenty of technologies for safe driving can not prevent traffic accidents, if a driver does not understand what safe driving is exactly. Thus, driver education is quite important even if ITSs spread. However, most educational methods about safe driving are subjective and lacking in...
When we attend class, we frequently take notes. The method of taking note means writing much information as a paper record. However, we cannot write it down in the notebook if there is no visual feedback information. We propose a pen-based note-taking system, which is named the 'pen-talker' on the ultra mobile PCs for blind person. A blind novice user with acquired blindness is able to input Japanese...
This paper proposes face recognition based on dominant frequency feature and multiresolution metrics. Dominant frequency feature is a small part of face frequency component that represents face information. Dominant frequency feature is extracted by selecting small percentage discrete cosine transforms coefficients that have big magnitude value. Matching process is done by multiresolution metrics...
In this paper, a robust Kalman filter and a bank of Kalman filters are applied in fault detection and isolation (FDI) of sensor and actuator for aircraft gas turbine engine. A bank of Kalman filters are used to detect and isolate sensor fault, each Kalman filter is designed based on a specific hypothesis for detecting a specific sensor fault. In the event that a fault does occur, all filters except...
As a good classifier, BP neural network has been applied in many engineering research questions. However, because of some inherent shortages, especially chaotic behaviors in the network learning, it is very difficult or impossible to apply the artificial neural network into precise diagnosis of large rotating machinery, such as the diagnosis of unbalance fault, etc. Based on good properties of the...
This paper mainly focuses on double-channel proportional control characteristic of the endoatmospheric spin rocket. The divided command model is built under spin condition and the control process is simulated in mathematic method. In the end, it is conclusion of spin rocket proportional control characteristic.
A self-enhanced SVM (support vector machines) building detection scheme is discussed. The scheme was designed for 1-metre resolution satellite imagery analysis. The scheme is a learning based segmentation without any prior prepared training data set. In the initial stage, an adaptive two-dimension Otsu algorithm is adopted to segment the image primarily into buildings and non-buildings. Then the segmented...
General fuzzy reasoning methods, e.g. Mamdani's method and the same kinds, can deal with fuzzy input and fuzzy output. But, its fuzzy outcomes are liable to be complex shape membership function. Therefore, its representative value is generally obtained by defuzzification technique, and is used as a reasoning result. This paper proposes the Particle Fuzzy Reasoning Method that deals with fuzzy input...
This paper deals with stability analysis and control design for a class of nonlinear systems with input constraint when using T-S fuzzy model. After leading the control design to LMIs approach, the attention is paid to 1) how to easy the LMIs conditions so that the system is asymptotically stable in a so-called ellipsoid to be made as large as possible; and 2) how to relax the LMIs conditions so that...
Designed wireless data communication system and researched wireless network application in the industrial control environment in this paper. Introduced the wireless data communication between PC and Sunplus 16 bit MCUSPCE061A based on PTR8000. The hardware and software design was given between the MCU SPCE061A and the PTR8000, and verified SPI communication and RS-232 serial communication. The effective...
This article describes the design and development of knowware system to support automatic construction of knowledge-based systems in various application domains. It first introduces the research background and intelligent components of knowware system, and then discusses a possible development.
As business enterprises and industries worldwide are increasingly becoming dependent on using online transactions, the demand for high-end and efficient transaction monitor systems becomes a serious issue. This paper presents a new cutting-edge Virtual Machine-based TPC-C Benchmarking and Analysis System, a unique platform for testing the efficiency of a TP (Transaction Processing) monitor for processing...
This paper describes a trial of robot learning allowing the evaluation policies based on embodiment in the teach- ing environment with multiple instructors. We have devel- oped a novel method which allows a robot to learn from di- rect demonstrations performed by multiple instructors. This method based on DP matching and clustering. It classi- fies the teachings from multiple instructors, integrates...
In the field of the pet robot and robot therapy, the creatural motion is important for the robots imitated the form of various animals. This paper presents the generation method of animal gait for quadrupedal robot. Here, we have employed AIBO as experimental quadrupedal robot and created the gait of AIBO in imitation of animal gait. At first, We have optimized the orbit of mono-leg, which can output...
