Given two programs, say P and Q, a differentiator is test suite T such that execution of Q on produces different outcomes; this concept used in mutation testing, where it important to highlight semantic differences between non-equivalent mutants. specification R program P, detector disproves the correctness with respect R; clearly useful testing. In note I elaborate previous research refine cha...

Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...

The concept of group detection is introduced to address the design of suboptimum multiuser detectors for CodeDivision Multiple-Access (CDMA) channels. A group detection scheme consists of a bank of P group detectors, one each for detecting the information symbols of users in each group of a P group partition of the li simultaneously transmitting users. In a parallel group detection scheme, thes...
