this paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. different railways use different threshold radius from 91m to 365m to provide restraining rail. these threshold figures are probably experience driven choices. the need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

Abstract To reduce the background z -Vertex Track Trigger estimates collision origin in Belle II experiment using neural networks. The main part is a pre-trained multilayer perceptron. task of this perceptron to estimate -vertex suppress from outside interaction point. For this, low latency real-time FPGA implementation needed. We present an overview architecture and neuronal network preprocess...

OBJECTIVE Despite documented associations between stunting and cognitive development, few population-level studies have measured both indicators in individual children or assessed stunting's associations with other developmental domains. DESIGN Meta-analysis using publicly available data from fifteen Multiple Indicator Cluster Surveys (MICS-4) to assess the association between stunting and de...

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...

for each X such that blood-disorder(X) appears in the database for each Y such that symptom(X, Y) appears in the database for each Z such that involves(Y, Z) appears in the database if Z=gastrointestinal-track then return true return false Of course, this is a simple case of automated reasoning; it doesn’t really use much in the way of inference rules. However, even simple examples like this ca...
