Ideal free distribution theory predicts that increased conspecific density redistributes individuals to low-density, suboptimal habitat. However, possible lags in response to population density remain poorly documented. Snowshoe hares (Lepus americanus) may exhibit density-dependent habitat selection due to its marked variation in population density. Based on 11 years (2004-2014) of snow tracki...

car body acceleration is an important factor affecting track safety and ride comfort, which are two primary aspects of railway systems. though track level is an important source of wagon body acceleration, no quantitative relation between them is available and the aim of this paper is to propose a method to address this issue. to do so, car body acceleration is determined using a 10 dof simulat...

ALICE is the dedicated heavy-ion experiment at CERN Large Hadron Collider (LHC). Its main tracking and particle-identification detector a large volume Time Projection Chamber (TPC). The TPC has been designed to perform well in high-track density environment created high-energy collisions. In this proceeding, we describe track reconstruction procedure ALICE. particular, focus on two challenges t...

lateral resistance of railway track is one of the most important parameters in lateral stability. this parameterdepends!on the conditions of different components of ballasted railway track (such as density of ballast layer,sleeper spacing, type of sleeper, etc.). from this perspective, type of sleeper has an important effect on lateralresistance. however in some conditions, in technical and eco...

Solid state nuclear track detectors have been applied in di erent studies including nuclear physics, particle physics, archaeology etc. Makrofol, a particular group of thermoplastic polymers, is used for radon detection. High background track numbers in the foils cause big uncertainties for places where the radon concentrations are quite low. Therefore, it is of great importance to lower the ba...
