"Recently, researchers and scientists have made significant advances toward better detection, evaluation, and understanding of the complex interactions of toxicants in environmental settings. Using information gathered at an international conference sponsored by the University o…

Polymer materials such as Polycarbonate (PC), Polymethyl methacrylate (PMMA) have numerous applications in transparent armor which includes body and face shield, helmet, windows of the armored vehicle etc. The most challenging part of these applications is to ensure the safety o…

Short-horned grasshoppers (Orthoptera: Acrididae) were studied in the field as well as in laboratory for their distribution, identification, preferred food plants and feeding damage. These grasshoppers compete for forage with cattle. Examination of the 20 most common grasshopper…

This study evaluates the effect of formation damage on horizontal well performance. A computer model in the FORTRAN language is developed in this study. The model describes the fluid flow interaction between the reservoir and the wellbore, taking into account the combined effect…

A combined analytical and experimental work is described to demonstrate the application of Laser Ultrasonic techniques for monitoring long term performance (Durability) of thick-section Pultruded FRP composites. Damage is induced in the material using both environmental and mech…

PQuake™ is an integrated digital system that facilitates earthquake damage reconnaissance. It combines digital photography, handheld GPS technology and custom software for a Palm® handheld computer to provide a user-friendly field data collection system. It mitigates the deficie…

Mechanical vehicle systems operate in highly variable loading environments. Anticipated and unanticipated degradations occur in components and subsystems due to the variability in static and dynamic loading. Degradation can lead to excessive warranty costs and overly aggressive …
