In this paper we present a component based person detection system that is capable of detecting frontal, rear and near side views of people, and partially occluded persons in cluttered scenes. The framework that is described here for people is easily applied to other objects as well. The motivation for developing a component based approach is two fold: rst, to enhance the performance of person ...

lateral flow assay, a simple and rapid test to detect various agents; have found many applications in different fields. one of the most important issues in the construction of a lateral flow assay is the increasing of its sensitivity and efficiency by processing of analytical layer. this study, aimed to investigate the performance of, nellulose, nitrocellulose, nylon and pvd as different analyt...

background: availability of antiretroviral therapies has transformed aids into a manageable chronic condition and im­proved well-being among people living with hiv/aids (pha) in developed countries. in developing countries however, such transformations are yet to occur due to socio-economic, systemic and environmental constraint. this study examined the impact of social, economic, psychological...

A major goal of this research is to present a framework for discussing issues and questions around Web Information Systems (WIS). WIS dynamically generate their contents, and thus require some mechanism to automatically infer metadata about WIS objects, infer access to relationships (i.e., links) among information objects, and provide hypermedia functionality such as annotation and ad hoc (user...

Small low-cost multimedia sensors ubiquitously capture and transmit multimedia information from fields to central stations in support of applications. However, Multimedia sensors in Wireless Multimedia Sensor Networks (WMSNs), have limited resources in terms of their computational capability, memory capability, bandwidth, and battery power, which hinder a wide application of WMSNs. The challeng...

A new method is presented to recover the depth ordering of motion layers in a scene. We derive a measure for determining the occlusion relationship between two layers, by testing whether the support of one motion layer is moving with the predicted local velocity of another motion layer. This is used to construct a graph which represents the depth ordering of all layers. By cascading two rst-ord...

Web information contain plentiful, significant knowledge which is eager to be explored by users. Effective semantic layered technology not only can provide theoretical support for knowledge discovery in Web resources, but also can improve the searching efficiency of the related information system. This paper builds the multi-layer theory of association semantic based on the power-law distributi...

in this work, the interfacial interfacial polymerization (ip) technique was employed using terephthaloyl chloride (tpc) and p-phenylenediamine (ppd), as reactant monomers, to prepare poly(paraphenylene terephthalamide) thin film composite (tfc) nanofiltration on polyethersulphone (pes) support layer. the effects of six different anionic and non-ionic surfactants, in the aqueous phase on the mor...

The research reported in this thesis has been focused on developing and analyzing how to support real-time traffic over a switched Ethernet network without any hardware or protocol modifications. The work has resulted in a proposed systems model, supporting both real-time and non real-time traffic. Currently this model is intended for a one-switch network, with no shared media. All added traffi...
