ABSTRACT
BLAST is a wireless communications technique which uses multi-element antennas at both transmitter and receiver to permit transmission rates far in excess of those possible using conventional approaches.
In wireless systems, radio waves do not propagate simply from transmit antenna to receive antenna, but bounce and scatter randomly off objects in the environment. This scattering known as multipath, as it results in multiple copies (images) of the transmitted sign arriving at the receiver via diff ....etc

The Abrasiive Blast Cleaning is the cleaning of the surface by the action of granular abrasives propelled either by compressed air through a nozzle or by using a vaned hardened steel blast wheel.Abrasive Blast Cleaning provides a method of surface preparation that is rapid and well established. Blast cleaning in its purest sense,relies primarily on mechanical forces(rather then chemical) to achieve cleaning performance.To blast clean,some form of media needs to be directed and ?blasted? via some method of delivery,towards a surface.The mechanis ....etc

Over the last decade, particle tracking microrheology has matured as a new tool for complex fluids research. The main advantages of microrheology over traditional macroscopic rheometry are: the required sample size is extremely small (~ 1 mL); local viscoelastic properties in a sample can be probed with high spatial resolution (~1-10 mm); and the sample is not disturbed by moving rheometer parts. I will present two examples of recent work in my group that highlight how these characteristics can be exploited to acquire unique information about t ....etc
