Solar chimney power plants are plants based on solar thermal power including three parts of collector, chimney and turbine, which is able to produce electrical energy. One of the effective parameters in increasing the power production is the collector angles versus horizon. In the present study, a numerical analysis of a solar chimney power plant for different angles of the collector (divergent...

Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach a common computational platform. Mobile Computing is a Generic word that introduces using of movable, handheld devices with wireless communication, for processing data. Mobile Computing focused on providing access to data, information, services and communications anywhere an...

Generational garbage collection is an established method for creating eecient garbage collectors. Even a simple implementation where all nodes that survive one garbage collection are tenured, i.e., moved to an old generation , works well in strict languages. In lazy languages, however, such an implementation can create severe temporary space leaks. The temporary space leaks appear in programs t...

The Florida Solar Energy Center (FSEC), with the support of the National Renewable Energy Laboratory (NREL), has investigated the thermal performance of solar absorbers which are an integral yet indistinguishable part of a building’s roof. The first roof-integrated solar absorber (RISA) system was retrofitted into FSEC’S Flexible Roof Facility in Cocoa, Florida in September 1998. This “proof-of...

Developing shared memory parallel programs using OpenMP is straightforward, but getting good performance in terms of speedup and scalability can be difficult. This paper demonstrates the functionality of a collector-based dynamic optimization framework called DARWIN that uses collected performance data as feedback to affect the behavior of the program through the OpenMP runtime, thus able to op...

We study the distributed privacy preserving data collection problem: an untrusted data collector (e.g., a medical research institute) wishes to collect data (e.g., medical records) from a group of respondents (e.g., patients). Each respondent owns a multi-attributed record which contains both non-sensitive (e.g., quasi-identifiers) and sensitive information (e.g., a particular disease), and sub...

Florida Department of Transportation (FDOT) sponsored research performed at the University of Florida resulted in developing a wireless monitoring and real time static capacity estimate technology for driven piles. This new technology, Embedded Data Collector (EDC), uses two levels of instrumentation, embedded in the body of precast prestressed concrete piles near the head and tip. Strain and a...

Wireless Sensor Network consists of a sink and a number of stationary nodes. In WSN, there are two major problems namely, limited energy and fault occurrence. In the proposed system, to decrease the energy consumption, the nodes are randomly deployed over an area. This area is divided into NxN square grids. At the center of each grid, a Mobile Sensor is placed, which moves in a criss-cross mann...
