So far, many studies on Double-Deck elevator systems (DDES) have been done for exploring some more efficient algorithms to improve the system transportation capacity, especially in a heavy traffic mode. The main idea of these algorithms is to decrease the number of stops during a round trip by grouping the passengers with the same destination as much as possible. Unlike what happens in this mode, where all cages almost always keep moving, there is the case, where some cages become idle in a light traffic mode. Therefore, how to dispatch these idle cages, which is seldom considered in the heavy traffic mode, becomes important when developing the controller of DDES. In this paper, we propose a DDES controller using genetic network programming with idle cage assignment algorithm embedded for a light traffic mode.

This paper deals with an attitude control of the space robot having two arms. These arms are located at both ends of the base, and they are perpendicular to each other, As there are no external torques, the inputs only act as internal torques generated by joint motors. By exploiting the non-integrability of the conservation law of angular momentum, the system can be expressed as a 5-state 2-input nonholonomic system that is controllable with second order of two generators. Based on time-state control form, the system can be transformed into two time-state control form subsystems. We propose a control strategy to switching each subsystem, The transformed subsystems are time-varying, the convergence in the neighborhood of the origin is assured based on quadratic stability by LMI.

Accompanied with recent trend of high-mix and low-volume productions, demands for performance of analog circuits used for facilities become difficult. As an advanced knowledge and know-how are needed in the design of an analog circuit, only expert designers can cope with the recent trend. In this paper, structural classifier system to support circuit design of filter circuit was proposed. This system involves three functions, optimization, classification, and retrieval of the related database which bring synergetic effects. Using these functions, a filter circuit is designed treating as a multipurpose optimization problem by GP. Efficiency improvement of the design is achieved through inferences referring similar circuit data as an external information. Each function was confirmed through a numerical experiment.

The purpose of this study is to improve rescue radar system with array antennas so that it can quickly identify far-off survivors under rubble. Authors focused on time-variable elements from the respiration of a survivor awaiting rescue in order to remove clutter components, such as the rubble. Authors propose the method which identifies the location of the survivor in three dimension by using the two dimensional array antennas. The experimental results of measurement for subjects location by the proposed method agreed with the actual location of the subjects.

In this paper, we propose a method of one-may delay estimation by using probe packets actively. We model the delay by geometric Brownian motion, and estimates parameters by fitting the coefficients of Fokker-Planck equation. Our method enables it to estimate clock skew at the same time.

This paper treats a relay-feedback mass measurement system that uses a relay with hysteresis and feeds back the velocity of the object. The efficacy of the proposed method has been already confirmed experimentally. In actual measurement, however, a spring-like element must be added for avoiding the drift of the object. The effect of this spring on mass estimation has not been investigated analytically. In this paper, an estimating equation including this effect is derived. The derived equation indicates that the estimated mass is smaller than the actual value when the conventional estimating equation is used. The experiments carried out in the fabricated apparatus support well the validity of the derived estimating equation.

Our final goal is to realize a system where the fingers on a keyboard can be used as a mouse. Such a system realizes more smooth operativity because the user needs not to move his/her hand between the keyboard and the mouse. We realized a function to discriminate between ldquopointing moderdquo (the mode to move the cursor according to the position of the fingertip) and ldquocharacter input moderdquo (the mode to input the character using the keyboard) based on handshape recognition using the image captured by a camera. A mouse click could also be realized by detecting the motion of a thumb in the pointing mode. As a result, a pointing system has been realized where both the pointing operation and the mouse click are possible using the motion of the right hand only on the keyboard.

For a robot to move autonomously in an unknown dynamic environment, a real-tune motion planning is necessary. When the motions of obstacles are unknown, motion planning is usually performed by virtually expanding the area obstacles occupy. However, there are many cases in which the adequate solution trajectory cannot be obtained due to inadequate expansion. Another approach would be to determine candidates of the safe trajectory from the layout of obstacles as a generalized Voronoi diagram and then randomly search for an appropriate trajectory. However, this requires many calculations. It may be sufficient if a local generalized Voronoi diagram is available for limiting the sampling area. Based on this idea, this paper proposes a Voronoi-based StRRT composed of an StRRT subjected to biasing extraction of sample points toward the border of a generalized Voronoi diagram and show the possibilities of this method to plan safe trajectories.

This paper presents a method to realize an operational transconductance amplifier (OTA) based adjustable floating resistor. The magnitude of the resulting resistance can be electrically varied by changing the external bias currents of OTAs. The proposed resistor is based on an active network termed ldquodual-output voltage-to-current (DO-V/I) converterrdquo, which is the OTA-based voltage-to-current converter with electronically variable property. The realization method provides both a positive and a negative resistance using the same scheme. The proposed design is attractive in the terms of simple configuration and low cost. Experimental results showing the circuit performance based on the use of the commercially available OTAs are includes.

A lot of papers have studied how to select accurate association rules for the users, and most of them make use of efficient statistical measurements, such as support, confidence, chi-square, lift, collective strength, and so on. However, it is still an open question about how to select a more proper statistical measurement for a certain user to find association rules in a certain domain. Since different measurements consider different interesting aspects of the association rules, we propose a novel method, named RuleRank, combining these statistical methods, in order to provide an alternative with more flexibility and robustness for users. In order to capture the userpsilas interest more closely, we also integrate semantic similarity into RuleRank model. The simulation results show that RuleRank model could give satisfying results for the user.
