PW cell is used to test radiated electromagnetic field immunity for small equipment up to frequency of several GHz. As the carbon absorbers as a microwave absorber are conventionally used for PW cell, the inside measurement space is limited to small sized EUT. For the tests in this report, we tried to use a pyramid ferrite absorber, which has been developed recently, instead of a carbon absorbe...

The Bickel-Rosenblatt (BR) goodness-of-fit test with fixed bandwidth was introduced by Fan in 1998 [Econometric Theory 14, 604–621, 1998]. Although its asymptotic properties have being studied by several authors, little is known about its finite sample performance. Restricting our attention to the test of uniformity in the d-unit cube for d ≥ 1, we present in this paper a description of the fin...

Power electronic equipment regulated by International Thermonuclear Experimental Reactor (ITER) must pass the relevant steady-state magnetic field immunity test. The main body of test is generator coil. Through mathematical derivation in this article, calculation formulas four-coil configuration under ideal and actual models are obtained. traditional method performance compared with general for...

introduction: the different factors that affect the camera uniformity of single photon emission computed tomography (spect) technique have been analyzed including peak shift (%) and window width of energy. the effect of peak shift and window width on spect image uniformity has been investigated using a point source to perform intrinsic flood images. methods:the relation between calculated integ...

Circular data are measured in angles or directions, which occur a wide variety of scientific fields. An often investigated hypothesis is that circular uniformity, isotropy. Frequentist methods for assessing the uniformity null exist, but do not allow user faced with an insignificant result to distinguish lack power from support hypothesis. Bayesian tests, solve this issue and several others, de...

Purpose: Evaluation of the newly integrated system for its validation and designing a quality assurance frame work to assess its geometrical, radiological and mechanical accuracy. Methods: Isocentric accuracy of two independent imaging modalities, kV based ExacTrac and MV based iViewGT was evaluated using Winston-Lutz test. A pelvic humanoid phantom was used for the radiological end-to-end test...

The development and application of a geometrically-based uniformity criterion is presented for film uniformity optimization in a radial-flow GaN epitaxy reactor system. In this multi-wafer reactor system, individual wafers rotate on a rotating susceptor in a planetary motion to reduce the effects of reactant depletion on deposition uniformity; the uniformity criterion developed for this system ...
