The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to deal with this kind of phenomena. The main purpose of this study is to construct an easy metho...

Simulation is often used to solve problems in many areas in the form of problem analysis. Real time graphic applications such as videogames typically use a continuous simulation scheme. This operating scheme has disadvantages that can be avoided by using a discrete event simulator as the application kernel. This paper proposes the integration of a discrete event simulator into a real time graph...

The meteorology and physico-chemical characteristics of aerosol associated with two new cases of long range dust transport affecting western Canada during spring 2006 are described. Each event showed enhancements of both sulfate aerosol and crustal material of Asian origin. However, the events were of quite different character and 5 demonstrate the highly variable nature of such events. The Apr...

Abstract. Hotspot is the part of a program where most execution time is spent. Detecting the hotspot enables the optimization of the program. The performance event counters embedded in modern processors provide the hardware support for the hotspot detection. By sampling the instruction addresses of the running program with performance event counters, hotspot of the program can be statistically ...

Based on reanalysis data, satellite ozone concentration observations, and a Lagrangian trajectory simulation, Rossby wave breaking (RWB) event its effect stratosphere–troposphere exchange (STE) over the Tibetan Plateau in mid-March 2006 were investigated. Results showed that increased eddy heat flux from subtropical westerly jet magnified amplitude of wave, which contributed to occurrence cyclo...

The τ Herculid meteor shower has not shown any appreciable activity since 1930. However, it is associated with Comet 73P/Schwassmann–Wachmann 3, a Jupiter-family comet that split in 1995. The fragments will pass near the Earth on 2006 May 13, and could produce an outburst of the τ Herculid shower. However, by considering both meteoroids released during the splitting event and on previous perihe...
