Method and Implementation for Wireless Message Authentication
Published Tuesday, October 16, 2007Most mechanisms of authentication (e.g., digital signatures and certificates) exist above the physical layer often with an additional cost in bandwidth. Researchers at the Department of Electrical and Computer engineering at the University of Maryland, College park, in collaboration with the Army Research Laboratory, have developed a new design...

Hybrid Causal Logic
Published Wednesday, April 18, 2007The invention relates to improving risk assessment analysis by the application of Bayesian Belief Networks for quantifying event sequence diagrams (hybrid casual models) and fault tree models. The quantification procedure was developed to quantify BDD/BBN configurations. However the procedure has more general applicability and can be...

Data Hiding in Compiled Program Binaries for Enhancing Computer System Performance
Published Wednesday, April 18, 2007Various techniques for reversible data embedding and lossless compression exist, such as those used for multimedia data. Certain of these algorithms use additive spread spectrum techniques while others embed supplemental data by modifying selected features, such as the Least Significant Bit (LSB) of the host signal. These techniques cannot be...

Fe Oxide Paint Composition for IRIS Tubes
Published Wednesday, April 18, 2007For soils to be considered hydric, they must demonstrate both saturation and anaerobic conditions in the upper part of the soil. Although several technologies are available for monitoring of soil water tables, documentation of reducing conditions is more problematic. This has led to recent interest in the use of IRIS (indicator of reduction in...

A New Approach to Contacting Nanowire Arrays Using Nanoparticles
Published Wednesday, April 18, 2007Despite significant advancements in nanowire growth techniques and device descriptions, establishment of electrical contacts to nanowire assemblies through non-destructive methods has not yet been successfully realized. The commonly employed method involves physically removing nanowires through some form of lithography. Such a series of steps are...

Transient Liquid Phase High Temperature Solder Paste Attach
Published Wednesday, April 18, 2007Solder is a metal or metallic alloy used, when melted, to join metallic surfaces together. The most common alloy is some combination of tin and lead. Certain tin-lead alloys have a lower melting point than the parent metals by themselves. The most common alloys used for electronics work are 60/40 and 63/37. Today there is an increased...

Genetic Polymorphisms Associated with Body Fat
Published Thursday, January 18, 2007Body compositions is determined by interactions between environmental, hormonal, genetic, and nutritional factors. Commercial broiler chickens have been selected for increased muscle mass and rapid growth. Unfortunately, selection for these desirable commercial traits has led to a concomitant increase in excessive fat deposition. This is an...
