The experience of ten years of studying dE/dx is summarised. First, a helpful, if qualitative, picture of the electromagnetic field of a relativistic particle passing through a medium is discussed. Second, the salient steps in a rigorous calculation of dE/dx are outlined. Results of calculations for a variety of gases and configurations are given and the weakness of the calculation is pointed o...

A study was conducted to evaluate the effects of social familiarity and initial BW variation at mixing on performance and welfare of pigs born to group-housed lactating sows. A total of 180 pigs from 24 litters were used in a random design with 4 treatments in a 2 x 2 (social familiarity x initial BW uniformity) factorial arrangement. Pigs were born in group-farrowing rooms where they mingled i...

In this paper, we study the problem of power efficient tracking interval management for distributed target tracking wireless sensor networks (WSNs). We first analyze the performance of a distributed target tracking network with one moving object, using a quantitative mathematical analysis. We show that previously proposed algorithms are efficient only for constant average velocity objects howev...

Waterfowl brood surveys were conducted in the Pah River Flats, Alaska during July of 1995. Duck production was not significantly different between plots burned in a 1992 wildfire and unburned plots for the third year following the burn. Fire did not produce any statistically detectable positive or negative effects on waterfowl production or habi­ tat in the first three years following the fire....

performance seismic evaluation is an important topic in earthquake engineering. in this regard, several methods have previously been developed and used. the main objective of present research is to evaluate two methods including “capacity spectrum method (csm)” and “improved capacity spectrum method (icsm)” in determination of seismic performance of concrete frames. for this purpose, several sa...
