introduction: one of the major causes of image non-uniformity in mri is due to the existence of non-homogeneity in rf receive and transmit. this can be the most effective source of error in quantitative studies in mri imaging. part of this non-homogeneity demonstrates the characteristics of rf coil and part of it is due to the interaction of rf field with the material being imaged...
There are two important aspects to good injector performance in rocket engines—the atomization performance (droplet size and distribution, for example) and uniformity of operation (even distribution of droplets in time and space). In general, both of these aspects are affected by the geometry and operating conditions of the injector. In studying atomization performance, prior work has largely f...
We return today to property testing and a surprising application of F2 estimation (or equivalently `2-norm approximation) for the problem of testing the closeness to uniform of a probability distribution. We consider discrete distributions on the domain [n]. Each such distribution is given by a probability vector p = (p1, . . . , pn). The uniform distribution U on [n] has Ui = 1/n for all i ∈ [...
UNLABELLED Uniformity testing is performed daily to ensure adequate camera performance before clinical use. The aim of this study is to assess the reliability of Beth Israel Deaconess Medical Center's locally built, centralized, Web-based uniformity analysis system by examining the differences between manufacturer and Web-based National Electrical Manufacturers Association integral uniformity c...
In this thesis, we step inside an unexplored region of Wireless Sensor Networks (WSNs) research. Nowadays, almost all WSNs research relies upon a hidden uniformity assumption. This assumption involves deployment, distribution and radio transmissions. Unfortunately, the real world is not uniform. In the thesis, we break the uniformity assumption and study the non-uniformity influence in WSNs. In...
The present study investigates the extent of genetic affinities and to trace their evolutionary history among the three Naga tribal groups of Manipur. Three DRD2 markers were screened among 200 individuals belonging to different Naga tribal (Rongmei=60, Inpui= 78, and Liangmai=62) groups using three sites (TaqI B, TaqID, and TaqIA) on the dopamine receptor D2 (DRD2) gene through allele and hapl...
The Caucasus, inhabited by modern humans since the Early Upper Paleolithic and known for its linguistic diversity, is considered to be important for understanding human dispersals and genetic diversity in Eurasia. We report a synthesis of autosomal, Y chromosome, and mitochondrial DNA (mtDNA) variation in populations from all major subregions and linguistic phyla of the area. Autosomal genome v...
