Web includes digital libraries and billions of text documents. A fast and simple search through this sizeable set is important for users and researchers. Since manual or rule based document classification is a difficult, time consuming process, automatic classification systems are absolutely needed. Automatic text classification systems demand extensive and proper training data sets. To provide...

The growing importance of Microgrid in future power systems highlights critical challenges like microgrid control and stability. An islanded including distributed generations (DG), energy storage (ESS), different types loads (static or dynamic) is prone to instability. whole system must be analyzed designed operate within stable regions. This study models an inverter-interfaced which supplies s...

One of the main factors affecting performance telescopic booms is loss local stability shelves and section walls. The sections occurs due to development plastic deformations in some most loaded or as a result stable equilibrium even at stage elastic deformation. In this case, maximum stresses boom are formed location supporting elements, where summation from external loads forces acting side el...

We consider the allocation of Virtual Arrays (VAs) in a Heterogeneous Disk Array (HDA). Each VA holds groups of related objects and datasets such as files, relational tables, which has similar performance and availability characteristics. We evaluate single-pass data allocation methods for HDA using a synthetic stream of allocation requests, where each VA is characterized by its RAID level, dis...

Continuously Heated Greenhouses: A production or retail greenhouse with a constantly maintained temperature of 50 degrees F or more during winter months. Such greenhouse must also have a maintenance attendant on duty at all times or an adequate temperature alarm system to provide warning in the event of a heating system failure. In addition, the greenhouse roof material must have a thermal resi...

virtual technology can be a useful tool for designing models of healthy urban environments. the resilience and sustainability in any urban environment involves the establishment and maintenance of the health of its citizens. the well-being of youth, the future workforce of every society, is a highly important consideration in the design of cities. cities are only truly sustainable when the work...

LEE, HEE WON. Network Emulation with Adaptive Time Dilation. (Under the direction of Mihail L. Sichitiu and David Thuente.) In order to evaluate the performance of new network architectures and protocols, researchers have used diverse methods such as theoretical analysis, network simulation, testbed implementation, and emulation. Among these methods, emulation has been widely employed over the ...
