In this paper, optimized model was designed for the starting characteristic of the Single-Phase Line-Start Permanent Magnet Synchronous Motor by using the Design of Experiment. A field pole angle, thickness and distance from center axis of permanent magnet were selected as design factor. We executed the transient state characteristic analysis of 8 test models. The transient state characteristic analysis was executed by using the 2 dimensional Finite Element Method and the Time Difference Method. We checked the fact that the selected design factor affected starting characteristic of the Line-Start Permanent Magnet Synchronous Motor. Depend on this result we found the optimized design point by using the response optimization.

In this paper, the effect of volute area distribution on the performance characteristic curve of a centrifugal pump were numerically studied using a commercial CFD code. To reduce the shutoff head, maintaining head and efficiency at a design flow rate, the flat head-capacity characteristic curves in which the head varies only slightly with capacity from shutoff to design capacity are frequency required. In order to control the shutoff head of a pump, several volute area distributions were proposed as a main parameter with the same impeller geometry. The calculation results show that the characteristic curve of a centrifugal pump can be controlled by modifying the area distribution with the same volute outlet area.

Studies are being done to replace conventional refrigerants with alternatives that have low or no ozone depletion and greenhouse warming Potentials, yet possess appropriate pro perties for a refrigeration cycle. To achieve this goal, a consistent set of thermodynamic properties of the working fluid is required. A common problem with the possible alternative refrigerants is that sufficient experimental data do not exist, thus making it difficult to develp complete equations of state that can predict properties in all regions including the vapor-liquid equilibrium. One solution is the use of the generalized equation of state correlations that can predict thermodynamic properties with a minimum number of characteristic parameters. Characteristic parameters required for the generalized equation of state are, in general, critical temperature, critical pressure, critical volume and normal boiling temperature. In this study, estimation of these characteristic parameters of refrigerants by group contribution method is developed.

This thesis aims to report the result of an evaluation of the aerodynamic characteristic on the purchase conditional pantograph model that has developed for applying to the KTX-I. Development pantograph was derived the result of aerodynamic characteristic through a wind tunnel test. And design modification was proceeded to solve the difference of aerodynamic characteristic by pantograph's operating direction. The verification test and adjustment test about the modified pantograph's aerodynamic characteristic were progressed on the KTX-I. To be corresponded with requirements, the airfoil and spoiler were used.

Information Systems Planning(ISP) has gained considerable interest among researchers and practioners in recent years because of the impact of information systems on organization performance. This study aims at analyzing organizational characteristic factors, information system characteristic factors influencing ISP's performance. The organizational characteristic variables are considered organizational strategy, organizational culture, and managerial leadership. And the IS characteristic variables are considered IS resource and IS strategic role. The ISP's performance variables are measured BP-ISP integration effectiveness and ISP efficiency. For data on the 493 sampled company, a mail survey using a questionnaire was conducted in this study. The following results were obtained. First, there was significant relationship between organizational characteristics and ISP's performance. Specially, organizational strategy and organizational culture affect the both of BP-ISP integration effectiveness and ISP efficiency. Second, there was significant relationship between Information Systems characteristics and ISP's performance. Specially, IS resource and IS strategic role affect ISP efficiency.

This paper deals with analysis on dynamic characteristic and circuit parameter of linear switched reluctance motor by electromagnetic analytical method. Above all, using space harmonic method, which is electromagnetic method, the air-gap flux density is analyzed in the both align and unaign positions, and the inductance profile, force characteristic and resistance per phase are calculated by means of the process. The validity of the analyzed results are demonstrated by the finite element method(FEM) and manufacture of the prototype machine. Second, the dynamic simulation is analyzed by the use of circuit parameters derived from analytical method, and the operating system of the prototype machine is manufactured to demonstrated the validity of simulation analysis. As a result, it is considered that the characteristic equation suggested in this paper will contribute to the design, analysis and application of LSRM.

The characteristic evaluation of an aluminium filler tube for automotive is presented in this paper. The material of filler tube was used AL3003 aluminium. In characteristic evaluation of an aluminium filler, we measured the corrosion, chemical resistance, weight, leak, welding strength, exciting endurance, and the solt spray test etc.. It has been shown that the weight decreased approximately 61% in aluminum filler tube developed comparing with steel filler tube. As the characteristic evaluation on the manufactured aluminium filler it was enough satisfied to use at the automotive filler tube.

This paper presents the joint characteristic function of the first- and second-order polarization-modedispersion (PMD) vectors in installed optical fibers that are almost linearly birefringent. The joint characteristic function is a Fourier transform of the joint probability density function of these PMD vectors. We regard the random fiber birefringence components as white Gaussian processes and use a Fokker-Planck method. In the limit of a large transmission distance, our joint characteristic function agrees with the previous joint characteristic function obtained for highly birefringent fibers. However, their differences can be noticeable for practical transmission distances.
