A CBMeMBer filter for extended object detection and tracking using box particle is proposed for the problem that measurement affects by inaccuracy and vague in extended target tracking. Firstly, states and observations of extended target are modeled as a Bernoulli random finite set and a Poisson random finite set respectively. Then the Bernoulli filter is implemented based on interval analysis, the...
Numerical analysis is an important process for creating reliable numerical software. However, traditional analysis methods rely on manual estimation by numerical analysts, which is restricted by the problem size. Although some state-of-art software packages can check whether a program is numerical unstable, they cannot tell whether it is caused by ill-posed problem itself or by some improper implementation...
Nowadays SIMD extensions became ubiquitous for computational platform, being widely used in signal processing, multimedia, and scientific applications. However, compilers still have difficult in vectorizing some applications, such as computations on non-contiguous and especially interleaved data, and loop nest for which inner loops that carry all the dependencies and external loops with strided memory...
According to the shortage of analysis software for temperature control while massive concrete structures were widely used, the special temperature control aided analysis software (TCAS) was developed. A mature Fortran program was applied with a precise method for pipe cooling calculation added during development. Friendly graphic user interface was developed, by using Microsoft foundation classes...
The reuse-rate of vector register is one of the most important aspects that influence the SIMD performance. However, the reuse of vector register probably can lead ton on-continuous memory access and non-hit of cache. Based on register reuse analysis, we establish a cost analysis that guide the multiple code generation. Then we perform NPB test based on different problem-scale and the result shows...
An improved form of basic genetic algorithm: Niche genetic algorithm which is based on sharing function is designed. It is aiming at the premature problem of basic genetic algorithm that existed in the back analysis of parameters of concrete thermal field. According to the measured temperature of concrete of rock anchor beam during construction period, its program composition is used to carry out...
In order to reduce the speed gap between today's processor and memory, many processors adopt multithreading technology, Intel IXP series Network Processor (NP) is such a typical kind. This paper takes IXP series Network Processor for example, first analyzes multithreading mechanism; then targeting on how to realize multi-thread synchronization, presents three design methods and a specific example...
