  particle filters
The aim of this paper is to propose a unified tracking framework using particle filters to efficiently switch between visual tracking (field of view tracking) and track prediction (non-overlapping region tracking).
      
However, particle filters are not used in practice for these applications mainly because they cannot satisfy real-time requirements.
      
There are many applications in which particle filters outperform traditional signal processing algorithms.

The influence of application of disposable infusion sets on particulate matter was systematically studied. It was proved by tests with Coulter Counter TA Ⅱ and Umbrellashed-type Clarity Aid that the increment of particles of 2 to 5 μm after inserting the disposable infusion sets was able to be as 1.6 to 27.6 times as before and visual spots peeled off from inserting rubber stopper were generated in the solutions. Furthermore it was proved by tests that the use of particle filters in infusion sets facilitated...

The radon daughter and dust cleaner consisting of three stages highly-effective fabric filtering and moderate/high-efficiency radon daughter particles filtering,when used in the area where air supplying is difficult,can clean the recirculating air at working face not only meeting the demand for radon daughter and dust cleaning,but also saving energy. Experiments indicate that,if the volume of the space to be cleaned is assumed constant, the effectiveness of the cleaner mainly depends on the cleaning efficiency and the air rate treated,and that the cleaning efficiencies for radon daughter,total dust and respirable dust are up to 95%,99% and 95% respectively.

The transfer processes of organic pollutants during the mixing of sewage and seawater were simulated by three different mixing systems, followed preliminarily the following re sults. A certain release of particulate organic materials is found in sewage particle-filtered seawater system. The release processes can be formulated by [t/X (t) ] = [t/X (eq) ] + B' and the estimated equilibrlum release of organic pollutants approximates to that of determina tion. The release rate is between 0. 02~0. 04d'-1 Neither adsorption nor release is observed in nature seawater-filtered sewage system and seawater-sewage system. Biochemical degrada tion of COD is found in all the three mixing systems. The degradation follows the first order reaction kinetics: ln c= -kt + B and the value of k falls between 0. 04 and 0. 07d-1 in the experi mental conditions.

以3种不同混合体系模拟研究了城市污水与海水混合过程中有机污染物的转移。在“污水颗粒物-过滤海水”体系中,颗粒态有机物有一定的释放,释放率约在0.02~0.04d-1之间。释放过程可用交换平衡动力学模式描述。在“天然海水-过滤污水”和“海水-污水”混合体系中,未发现有机污染物有明显的吸附或释放。在这3种混合体系中均发现化学耗氧量(COD)的降解现象,降解过程符合一级动力学方程,降解速率常数在0.04~0.07d-1之间。
