  • The purpose of this study is to develop the computer software for the nonlinear analysis of R/C frame structure under static loads. For this purpose, strain-rate dependant material model and physical element model considering both flexural and shear deformation are adopted and they are connected with 'TWO-D'which is commerical software for elastic structural analysis. The analytical results using the developed software are compared to the experiment results and they are generally satisfactory.

  • 만약 Glenoid side를 해부학적으로 정확하게 치환하고, 상완골측의 prosthesis를 삽입할 때 실제 골두의 크기와 같은 prosthetic head를 쓰고, humeral stem의 위치 및 높이를 정확하게 맞추어 삽입하여, humeral head component의 center와 glenoid component의 center가 일치되고 lateral glenohumeral offset이 정상에 가깝게 수술을 시행하면 인공 치환물로 대치된 glenohumeral joint가 정상에 가장 가까운 kinematics를 가질 수 있다 (당연한 얘기지만 이렇게 수술하려면 많은 경험이 필요). 따라서 Glenohumeral joint의 인공 관절 치환술은 항상 technique-dependant 수술이며, 아무리 좋은 치환물도 훌륭한 수술 기법보다 더 중요할 수는 없다.

  • Change of sintering shrinkage in alumina-based multilayer ceramics was observed in various lamination condi-tions and binder burnout (BBO) temperatures. It was found that the linear shrinkages in X and Y directions were nearly the same with the BBO temperatures but a large shrinkage difference in Z direction was observed. However this phenomenon was diminished when BBO temperature was increased. A linear relationship between the laminated density and the sintering shrinkage was found and the slope was independant on the BBO temperature but dependant on the shrinkage direction.

  • This paper presents characteristics of neuron-MOSFET for the implementation of logic circuits such at the inverter and D/A converter. Neuron-MOSFETS were fabricated using double poly CMOS process. From the measured results, it was found that noise margin of the inverter was dependant on the coupling ratio and a complete D/A characteristics of the source follower could be obtained by using any input Sate as a control gate.

  • In this paper, the problem of delay-dependent stability analysis for cellular neural networks systems with time-varying delays was considered. By using a new Lyapunov-Krasovskii function, delay-dependant stability conditions of the delayed cellular neural networks systems are proposed in terms of linear matrix inequalities (LMIs). Examples are provided to demonstrate the reduced conservatism of the proposed stability results.

  • The bottom friction model of combined wave-current flow developed by Bijker, Yoo and O'Conner (hereafter it is called BYO model) is fully based on the Prandtl's mixing length theory. Although the Prandtl's theory is dependant on some rationalism, it is widely recognized that the theory is generally acceptable for the description of any turbulent flow.(omitted)

  • In this study we investigate the reliability of a bar subjected to a random tensile load in presence of corrosion. We consider linear, quadratic and exponential models that connect the stress in the bar with the corrosion rate. Two probability densities are considered for the load, with attendant derivation of the time-dependant reliability. The design time of operation is determined utilizing the requirement that the reliability must not be less than the required value.

  • This paper is proposed that The voltage-dependant power factor model is established as 5th polynomials with convenience data type. This modeling includes the harmonic components by static experiments of individual and composite load. This paper suggested methodology for modeling bus and regional power factor with consideration of harmonics effect by load composition rates and individual load power factor models.

  • The safe operation of electro railways is greatly dependant on its protective systems. The system so-called Fault Protection Wire(FW) is now widely adapted to protect in AT feeding systems. It is connected between the feeder and trolley circuit to return the fault current to autotransfonmers at substation. This paper computed the distribution of fault currents at FW in the system and also evaluated the safety from electric shock when ground fault or flashover occur in the feeding system. The results show FW is useful to protect power supply network from fault in electric railways
