A Volumetric Display using VFD, and A Display Data Generator
Volumetric displays, which directly draw 3D images in the real 3D space, are expected to be used not only in science but also in art. However, most of these displays need complex and expensive optical systems, so they are rarely used in art. In this paper, we propose and describe a volumetric display that has no such optical systems and can be easily constructed using parts on the market. In th...
متن کاملDesign of VFD Drive for a 3-Phase Induction Motor
The main aim of the project dealt with the concept of speed control of a three-phase induction motor with energy saving. To do so, a VFD (Variable Frequency Drive) is used for controlling the speed of a three-phase induction motor with variable load attached to the motor. It certainly leads to the best performance and high efficiency of the induction motor. In recent years, a major issue that i...
متن کاملD ec 2 00 7 UNIVERSE DRIVEN BY THE VACUUM OF SCALAR FIELD : VFD MODEL
It is shown that in the Vacuum Fluctuations Domination model (VFD), where vacuum fluctuations of scalar fields dominates under matter and radiation throughout the all history of the Universe expansion (gr-qc/0604020, gr-qc/0610148), acceleration parameter evolves monotonically from the zero to the present day negative value. That is according to this model the Universe has no decelerating past ...
متن کاملHarmonic Measurement and Analysis of Variable Frequency Drive (vfd) in Industry
Utility of non-linear load leads to generation of harmonics in industry which is affecting the power quality as well as performance of devices like motors and controllers etc. Harmonic Measurement and analysis to obtain the harmonic content of current and voltage has become vital task in context with increasing power quality. This paper discusses the effect of harmonics on power system and the ...
