This paper proposes a layered container inspection system for detecting illicit nuclear materials using radiography information. We argue that the current inspection system, relying heavily on the Automated Targeting System (ATS) and passive radiation detectors, is inherently incapable of reliably detecting shielded radioactive materials, especially highly enriched uranium (HEU). This motivates...

Background: Due to changes in guidelines and access to treatment, more children start combination antiretroviral therapy (ART) in infancy. With few studies examining the long-term effects of perinatal HIV infection and early ART on neurodevelopment, much is still unknown about brain maturation in the presence of HIV and ART. Follow-up studies of HIV infected (HIV+) children are important for mo...

The discovery that antiretroviral interventions can prevent mother-to-child human immunodeficiency virus (HIV) transmission during pregnancy, delivery, and more recently, during breastfeeding, and implementation of these interventions in low-resource as well as highresource countries, has been one of the great success stories of the HIV epidemic. Increased global availability of combination ant...

The disambiguation of sentences is a combinatorial problem. This paper describes a method for treating it as such, directly, by adapting standard combinatorial search optimizations. Traditional disambiguation heu-ristics are applied but, instead of being embedded in individual decision procedures for specific types of ambiguities, they contribute to numerical weights that are considered by a si...

This Software for Design Activity in power plants Equipments helps the power plant engineers and managers to manage the development and design activities of equipments in the field of power plants. This paper is basically concerned with the computerization of the design activity of Condenser, vital equipment in Heat Exchanger Unit (HEU) of Thermal power plant required for condensing the steam a...

The speciication of eecient data distribution schemes is one of the major tasks in programming DMMPs with state of the art data parallel languages. Although there are no optimal strategies for generating such data distributions, several heuristics have been developed to provide some support to the user. Alignment analysis, for instance, is able to provide help for choosing an alignment scheme w...

1 The fundamental goal of an electric utility is to serve its customers with a reliable and low cost power supply. This goal has led to a number of standard protection engineering practices that ensure adequate service; however, with deregulation of the utility industry and increased competitive pressures, there is a desire to further improve service reliability and reduce costs. In this vein, ...
