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...

Complex clinical problems involving huge experimental evidence require a preliminary validation of observed data. This may avoid biasing due to incorrect sampling and clarify the sample distribution by showing datainherent regularities. The paper describes the application of unsupervised models of neural networks to the analysis of a very large set of clinical records for the study of Osteoporo...

Various considerations liave constrained me to prepare this, guide. First, the Binet-Simon scale is coming into wider and wider use in institutions for defectives (feebleminded, epileptic, insane, criminal, juvenile delinquents) and in the public schools throughout the country. Such varied application of the tests should in time yield valuable comparative knowledge of various classes of individ...

Obstructive sleep apnoea syndrome (OSAS) results from upper airway collapse during sleep. It represents an increasingly recognized pathology associated with many diseases. Herein, we describe a database for patients with OSAS. This has different goals: to facilitate good uniformity in clinical assessment, to allow the use of the application even by non-ENT specialists, to evaluate the results o...

Introduction: Surface coil arrays are particularly suitable for spinal cord MR imaging. Demand for higher channel count systems has lead to an increased need for optimized performance of constituent coil elements in order to obtain high SNR, adequate penetration depth, ease of isolation, and uniformity of response. In this study we have analyzed the performance characteristics of 6 different ar...

Let No be Conway’s class of surreal numbers. I will make explicit the notion of a function f on No recursively defined over some family of functions. Under some ‘tameness’ and uniformity conditions, f must satisfy some interesting properties; in particular, the supremum of the class ̆ x ∈ No : f (x) ≥ 0 ̄ is actually an element of No. As an application, I will prove that concatenation function x ...

Lexical Markup Framework (LMF, ISO24613) is the ISO standard which provides a common standardized framework for the construction of natural language processing lexicons. LMF facilitates data exchange among computational linguistic resources, and also promises a convenient uniformity for future application. This study describes the design and implementation of the WordNet-LMF used to represent l...

Evaluation of irrigation system performance facilitates objective analysis of the typical as opposed to the potential performance of various types of irrigation systems and the respective management criteria, appropriate for local conditions. This information can also help with the selection of one system over another given local constraints. The impact that the application uniformity of a syst...

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 ∈ [...
