Construction cost index is generally used to estimate the new project cost based on past construction data and to adjust contract cost when the price change of various articles and items of expenditure composing the contract occurs. In Korea, it is mostly used for adjustment of construction contract cost due to fluctuation of prices. However index adjustment rate which is used for adjustment of construction contract cost had some problems in calculating cost index of each expenditure item that could not reflect properly the change of construction cost. For supplementing these problems, the research of developing construction cost index has been executed. Through the precedent research, these problems were partially resolved but still remain. Therefore this research proposes method of making cost index that utilizes representative items of labor, material, and equipment by analyzing bill of quantity of road construction, through analysis and comparison of precedent study. By using this method, it is expected to solve problems which were not reflected in precedent studies.

A new time series method, directional ARMAX (dARMAX) model-based approach. is proposed for rotor dynamics identification. The dARMAX processes complex-valued signals, utilizing the complex modal testing theory which enables the separation of the backward and forward modes in the two-sided frequency domain and makes effective modal parameter identification possible, to account for the dynamic characteristics inherent in rotating machinery. This paper is divided into two parts : The dARMAX modeling, analysis. and fitting strategy are presented in the first part. whereas a evaluation of its performance characteristics based on both simulated and experimental data is presented in the second.

Polarized Fourier transform infrared (IR) absorption is used to probe molecular conformation in a ferroelectric liquid crystal (FLC) during the reorientation induced by the external field. Spectra of planar aligned cells of FLC W314 are measured as functions of IR polarizer orientation and electric field applied to the FLC. The time evolution of the dichroism of the absorbance due to biphenyl core and alkyl tail molecular vibration modes, is observed. Static IR dichroism experiments show a W314 dichroism structure in which the principal axis of dielectric tensor from molecular core vibration are tilted further from the smectic layer normal than those of the tail. This structure indicates the effective binding site in which the molecules are confined in the Sm-C phase has, on average, "zig-zag" shape and this zig-zag binding site structure is rigidly maintained while the molecular axis rotates about the layer normal during field-induced switching.

By adjusting the applied Software Method, One Physical Pallete can execute each colored Icon. Each Pallete includes Image's data and Image's Color data.Color data is composed of hex data by generating Pallette tool. This data is loaded by selecting Icon. Icon's selection is composed of current selected Icon and non-selected Icon by user. We must draw on these states to Meun's Icon.

Recently, the fuel charge is accounted for very high in the navigation cost. Therefore Shipowner is tried to find method for reducing oil consumption. ERCS(Energy Reduced Cooling System) is one of the method. The ERCS algorithm operates to decrease a power consumption of main sea water cooling pump through inverter control. We have developed ERCS controller with algorithm. The ERCS controller consists of CPU board, Digital I/O board, A/D board, D/A board and LCD/SW board. We tested with dummy signal to confirm the algorithm working correctly and achieved the good results. Before soon we will test under real condition in the ship and expect to get the result as forecasted.

The dream is a well-known experience in the routine life. It is necessary to consider the dream to modality of diagnosis because many evidences that the dream represents the physiologic and pathologic changes in the human have been proved in recent days. The oneironosus(病夢) was caused by three factors, which are the external stresses of the body, malfunction of Jang-Bu(臟腑) and irregular of Yin-Yang(陰陽) and Gi-blood(氣血). The oneironosus(病夢) reflects the location, characteristics, progression and prognosis of the disease. In addition, it predicts the development of disease. The principle of treatment for the oneironosus(病夢) is making an effort for the stabilization of mind by eradicating the internal and external factors that make the spirit(神) been unstable.

Gait recognition, as a promising biometric, can be used in video-based surveillance and other security systems. However, due to the complexity of leg movement and the difference of external sampling conditions, gait recognition still faces many problems to be addressed. In this paper, an improved convolutional neural network (CNN) based on Gabor filter is therefore proposed to achieve gait recognition. Firstly, a gait feature extraction layer based on Gabor filter is inserted into the traditional CNNs, which is used to extract gait features from gait silhouette images. Then, in the process of gait classification, using the output of CNN as input, we utilize metric learning techniques to calculate distance between two gaits and achieve gait classification by k-nearest neighbors classifiers. Finally, several experiments are conducted on two open-accessed gait datasets and demonstrate that our method reaches state-of-the-art performances in terms of correct recognition rate on the OULP and CASIA-B datasets.

This paper investigated application of fractional-slot concentrated-winding axial flux permanent magnet machines for wind turbines. Design criteria of cogging torque and voltage regulation was firstly proposed for this kind of application. Fractional winding has small cogging torque which is highlight for wind turbines, but slot leakage inductance would increase voltage regulation, which is an important performance index of generators. By varying slot opening, cogging torque and slot leakage inductance could be adjusted. In this paper, cogging torque and inductances were calculated by both analytical and finite element methods. Voltage regulation was studied by two-axis model under unity-power-factor load and verified by transient finite element analysis.
