The ISA-17 Quantification Challenge: Background and introduction

This paper, intended for the ISA-17 Quantification Annotation track, provides background information for the shared quantification annotation task at the ISA-17 workshop, a.k.a. the Quantification Challenge. In particular, the role of the abstract and concrete syntax of the QuantML markup language are explained, and the semantic interpretation of QuantML annotations in relation to the ISO principles of semantic annotation. Additionally, the choice is motivated of the test suite of the Quantification Challenge, along with the suggested markables for the sentences of the suite.

A Simulation of gain filters to target tracking in radar system by using Matlab

The most important problem is to reduce radar signal noise ,so we must design a pattern to process signal from source to destination. We might study target tracking by using Kalmen filters which estimate the exact statistical average signals and put a mathematical relationship to the optimal detection technique for radar system with two variations (position, velocity) and three variations (position, velocity, acceleration). Then, we compare these filters by Matlab to check the least value for the studied error.

Study of the behavior of the railway under train movement by changing the components of permanent way

In this paper, the effects on the wave shape will be studied according to the track permanent components such as rail, sleepers or ballast. The results show there is a step change in stress on the ballast layer. It is important to prevent the step change in the track characteristic module over 20%. It is also useful to provide a transition zone to allow the gradate changing in track characteristic module.
