Genome-wide association studies have identified many candidate causal variants associated with common complex diseases and traits, but most of them have been drawn from nonrandomized case/control designs. In nonrandomized experiments, the results drawn from two different groups can be misleading because the units exposed to one group generally differ systematically from the units exposed to the other...
Due to tragic event of Sep. 11, 2001 and experimental evidence of a dirty bomb, a threat using by radioactive or nuclear material is becoming a worldwide problem. To monitor the status and position of in-transit nuclear material in South Korea, real-time monitoring system has been developed and tested. Test results showed that the developed system carried out successfully various functions to track...
D- and q-axis inductance are expected to have ripple characteristics due to the difference of magnetic saturation level of each axis. In this paper, inductance variation of the interior permanent magnet synchronous motor (IPMSM) is calculated with finite element analysis, and cause of inductance variation is analyzed. Finally the validity of this paper is verified by the comparison to the experimental...
This paper presents the numerical results of EMF waveform at the different types of structure in the interior permanent magnet synchronous machine (IPMSM). The numerical technique, fixed permeability method (FPM), has been used in order to analyze the EMF waveform considering load condition as well as no-load one. Furthermore, the relationship between total harmonic distortion (THD) of EMF waveform...
In this paper, finite element analysis (FEA)-based optimization using Internet distributed computing is proposed for the real world and complex optimization such as optimal design of permanent magnet dc motor
