This study examines how various elements characteristic of the traditional Japanese architecture are applied to contemporary architectural designs in japan. The issue of how to incorporate cultural tradition into architectural design has become one of central questions cast on modern architects. In this sense, the Japanese contemporary architecture has often been touted as infusing Japanese traditional elements into modern artifacts both functionally and aesthetically. That is, while Japanese architecture encompasses the essentials of Western modern techniques and styles, it obviously embodies Japanese tradition. Through the examination of various contemporary buildings in Japan, this study specifically explores how the vernacular forms and elements unique to Japan are reinterpreted and reinvigorated in contemporary architectural designs.

In this paper, we propose a method of designing neural networks using biological inspired developmental and evolutionary concept. The living things are best information processing system in themselves. One individual is developed from a generative cell. And a species of this individual have adapted itself to the environment by evolution. Ontogeny of organism is embodied in cellular automata and phylogeny of species is realized by evolutionary algorithms. The connection among cells is determined by a rule of cellular automata. In order to obtain the best neural networks in the environment, we evolve the arrangement of initial cells. The cell, that is neuron of neural networks, is modeled on chaotic neuron with firing or rest state like biological neuron. A final output of network is measured by frequency of firing state. The effectiveness of the proposed scheme is verified by applying it to navigation problem of robot.

A Chebyshev spectral method (CSM) for the dynamic analysis of non-uniform Timoshenko beams under various boundary conditions and concentrated masses at their ends is proposed. The matrix-based Chebyshev spectral approach was used to construct the spectral differentiation matrix of the governing differential operator and its boundary conditions. A matrix condensation approach is crucially presented to impose boundary conditions involving the homogeneous Cauchy conditions and boundary conditions containing eigenvalues. By taking advantage of the standard powerful algorithms for solving matrix eigenvalue and generalized eigenvalue problems that are embodied in the MATLAB commands, chebfun and eigs, the modal parameters of non-uniform Timoshenko beams under various boundary conditions can be obtained from the eigensolutions of the corresponding linear differential operators. Some numerical examples are presented to compare the results herein with those obtained elsewhere, and to illustrate the accuracy and effectiveness of this method.

Asymmetrical reinforcement for circular sections in wall piles is an efficient construction component with reduced embodied energy. It has been proven that asymmetrical reinforced wall piles may save more than 50% of the reinforcement than the traditional symmetrically reinforced circular sections. The use of this new type of structural member increases the number of variables in the design problem, which makes its use by engineers more complicated. In order to facilitate the use of the asymmetrically reinforced piles, this paper presents a criterion for the design of this type of structural member. The chosen criterion has been analyzed with the help of flexural capacity-cost curves. The new criterion is similar to the design procedure traditionally used for RC beams.

Decision of operation performance mode to minimize the energy consumption of urban rail vehicle. This paper analyses how much acceleration and deceleration of urban rail vehicle should be applied andhow to choose an operation mode to minimize energy consumption when train runs between station within the fixed operation time. The decided operation pattern satisfying the minimum energy consumption becomes a target trajectory and a basis for the controller design criteria. To make this goal it grasps the characteristics of urban rail vehicle, realize operation energy model of urban rail vehicle and verify the accuracy of embodied model the Matlab simulation with the same operation result of real route. It searches for operation pattern to minimize operation energy by changing the acceleration and deceleration on the imaginative route and proposes operation pattern minimizing energy consumption by applying real operation data between Dolgogee-Sukgye section of Seoul Metropolitan Subway Line 6.

characteristic of wear between wheel and rail is important factor of judgement to maintenance. KHST is optimized on an exclusive rail, UIC60. but also KHST is running on the variety existing line as well as KS50N, KS60 et,c. Hail profile of KS50N is dissimilar to DIC60. So we can predict that characteristic of wear is embodied also different. In this paper. we deduced the force and point of contact position between wheel and rail through multi-dynamics analysis and predicted wear of wheel and rail through contact problem analysis. we used simplified theory of kallker on contact problem, and Predicted the wear phenomenon of wheel using archard wear equation about each condition.

The automatic firewall block and fire alarm system was embodied by using gas circuit and wireless communication equipment, using a smoke sensor (ST-QA1A) and RF Module. OR-CAD was also used for testing circuit system and experiment circuit after assembling circuit. As a result in experiment, the gas sensor detected well an imaginary smoke and worked reliably for driving action of firewall block motor and wireless warning alarm. Through the smoke sensitive perception from the fire, the warning alarm and the preventing fire propagation from the specific closed region were verified reliably. The gas sensor and RF module for firewall and fire alarm system were actually available.

In this paper, we design hybrid limitter balanced(HLB) power amplifier with W-CDMA signal input. Balanced power amplifier is important component that decide efficiency in communication system. General balanced power amplifier has low efficiency and high distortion characteristics. Therefore, we embodied two path with limitter that amplitude path had high efficiency amplifier using limitter and phase path had high linear amplifier to improve such problem.
