This paper presents a framework to track multiple persons in realtime. First, a method with real-time and adaptable capability is proposed to extract face-like regions based on skin, motion, and silhouette features. Then, a two-stage face verification algorithm is proposed to quickly eliminate false faces based on the face geometries and the Support Vector Machine(SVM). In order to overcome the effect of lighting changes, a method of color constancy compensation is applied. Then, a robust tracking scheme is applied to track multiple persons based on a face-status table. With the table, the system has extreme capabilities to track different persons at different statuses, which is quite important in face-related applications. Experimental results show that the proposed method is much robust and powerful than other traditional methods.

Formation and coexistence of tricalcium silicate (C3S) and calcium sulphoaluminate (C4A3 $$ \bar S $$) minerals in Portland cement clinker containing calcium sulphoaluminate were investigated. The f-CaO content, mineral composite and formation of mineral in the clinker were analyzed respectively by chemical analysis, differential scanning calorimetry(DSC) and X-ray diffraction. The results show that, adding a suitable amount of BaO can

The purpose of this study was to optimize the preparation conditions of Lycium barbarum polysaccharides liposome (LBPL) by response surface methodology (RSM) and to investigate the effect of LBPL activating function of peritoneal macrophages. LBPL was prepared using the reverse-phase evaporation method. The optimal preparation conditions of LBPL by RSM were as follows: the ratio of lipid to drug (w/w) of 25:1, the ultrasound time of 14 min and the ratio of soybean phospholipids to cholesterol (w/w) of 2.4:1. Under these conditions, the experimental encapsulation efficiency of LBPL was 86.37±0.63%, which was close to the predicted value. These indicated that LBPL with high entrapping efficiency and small particle size could be prepared by the reverse-phase evaporation method, which is applied easily. Furthermore, macrophages are the key players in the innate immune system. LBPL could effectively enhance peritoneal macrophages phagocytosis and resulted in inducing NO (nitric oxide) production in mouse peritoneal macrophages.

A cluster is a group of computers which are loosely connected together to provide fast and reliable services. There have been many applications built on cluster systems such as distributed/parallel database applications, telecommunication systems and, recently, internet/intranet servers. Cluster systems can deliver similar or better performance and reliability than traditional mainframes, supercomputers and fault-tolerant systems with a much lower hardware cost

This paper studies the conditions under which peer-to-peer (P2P) technology may be benecial in providing IPTV ser- vices over typical network architectures. It has two major contributions. First, we contrast two network models used to study the performance of such a system: a commonly used logical \Internet as a cloud" model and a \physical" model that reects the characteristics of the underlying network. Specically , we show that the cloud model overlooks impor- tant architectural aspects of the network and may drastically overstate the benets of P2P technology by a factor of 3 or more. Second, we provide a cost-benet analysis of P2P video content delivery focusing on the prot trade-os for dieren t pricing/incentive models rather than purely on ca- pacity maximization. In particular, we nd that under high volume of video demand, a P2P built-in incentive model per- forms better than any other model for both high-denition and standard-denitio n media, while the usage-based ...

ABSTRACT The low-temperature sintering of (Ba0.6Sr0.4)(Ti0.94Cu0.06)O3 (BSTC) ceramics was investigated by conventional ceramics processing using a B2O3 sintering aid, and the dielectric properties and microstructures of the ceramics were examined. BSTC powders without B2O3 could not be fully densified at sintering temperatures lower than 1150°C. However, the addition of B2O3 markedly enhanced the sinterbility of BSTC powders, and the sintering temperature decreased from 1150 to 980°C. This may be due to the promotion of liquid-phase sintering. The 3 at.% B2O3-doped BSTC ceramics sintered at 980°C for 2 h exhibited a high density of 5.48 g/cm3. Transmission electron microscopy examination indicated that there are two kinds of secondary phases produced in BSTC ceramics during B2O3 addition; one is BaTi(BO3)2 with rhombohedral structure, and the other is Ba4Ti12O27 with monoclinic structure. The BSTC ceramics with 3 at.% B2O3 sintered at 980°C in air for 2 h exhibited a maximum permittivity, max = 1216, and a bulk density > 96% of theoretical density.

On the basis of previous test that selenizing Chinese angelica polysaccharides (sCAPs) with stronger immune-enhancing activity in vitro were picked out, the immune-enhancing activity in vivo of three sCAPs, sCAP2, sCAP6 and sCAP8, at high and low dosage were compared taking the unmodified Chinese angelica polysaccharide (CAP) as control by determination of peripheral lymphocyte proliferation, serum antibody titer, IFN-γ and IL-6 contents in chicken vaccinated with Newcastle Disease vaccine. The results showed that three sCAPs at suitable dosage could significantly promote lymphocyte proliferation, enhance serum antibody titer, IFN-γ and IL-6 contents as compared with unmodified CAP, sCAP2 at low dosage possessed the strongest action. These results indicated that selenylation modification could significantly enhance the immune-enhancing activity of CAP, sCAP2 possessed the best efficacy and would be as a component drug of new-type immunoenhancer.
