Technical Papers and Presentations

Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating characteristics. An emerging field is the study of acoustical properties of multi-scale porous materials. An example of these is a double-porosity granular material ... Read More

Transducer optimization is a key aspect for successful development and deployment of advanced sensors, especially when designing 3D structures for harsh environments. For piezoelectric transducers, plate thickness determines the operating frequency of the resonator, which is frequently ... Read More

A dual-trap optical tweezers is used for deforming the red blood cell (RBC) in suspension and studying its elasticity. The 3D deformation of the cells was computed with the elastic membrane theory. The calculated deformation can fit to experimental data resulting in cell’s elasticity ... Read More

Significant volumes of the worlds proved reserves are in dolostone reservoirs. Scope for recovery and success/upside of new exploration plays depend on the chances of encountering dolostone reservoirs with good reservoir properties. Although dolostones make excellent reservoirs in ... Read More

A novel combined photovoltaic-thermal panel can simultaneously increase the conversion efficiency of the PV cell and utilize some of the excess thermal energy created by the conversion process (see Figure 1). The Conjugate Heat Transfer physics in COMSOL was used to create a two ... Read More

NASA and the Department of Defense have interest in the development of satellites which are several orders of magnitude smaller than those currently in use. These ‘nanosats’ will require new propulsion systems to offer precise thrust and impulse-bit characteristics on the order of 10 ... Read More
