The optimal development of polymer nanocomposites using carbon nanotube (CNTs) and carbon nanofiber (CNFs) fillers requires a complete understanding of processing-structure-property relationships. The purpose of this understanding is to determine the optimal approach for processing polymer nanocomposites with engineered microstructures and enhanced
Even though numerous PRAs have shown that fire can be a major contributor to nuclear power plant risk, there are some specific areas of knowledge related to this issue, such as the prediction of fire-induced damage to electrical cables and circuits, and
Concurrent vibration and thermal environment is commonly encountered in the service life of electronic equipment, including those used in automotive, avionic, and military products. Though extensive research exists in literature for solder joint failures due to thermal cycling, limited research has been
In this work, piezoelectric resonators based on single crystal Al0.3Ga0.7As films are implemented. The combination of Si doped Al0.3Ga0.7As as electrode layers and moderate piezoelectric properties of updoped Al0.3Ga0.7As film leads to lattice matched single crystal resonators with high attainable quality factors
Large-eddy simulation (LES) of wall-bounded flows is limited to moderate Reynolds number flows due to the high computational cost required to resolve the near wall eddies. LES can be extended to high Reynolds number flows by using wall-layer models which bypass the
Supersonic mixing enhancement techniques are of considerable interest; typically qualitative observations of shear layer growth rate are used to compare these techniques. A more accurate assessment of the efficiency of various mixing techniques could be made using local species concentrations at specific
In order to maximize household refrigerator performance, it is important to understand the basic relationship between each component as well as the relationship between refrigerant and lubricant used in the system. This study examines the particular role of the accumulator in a
Liquid crystal displays are commonly used in various applications and subjected to numerous environmental and handling conditions that can especially affect the performance and life of these devices. In addition to humidity and temperature exposure, cyclic loadings and handling conditions (bending, repetitive
Phase change technology is a science that is continually finding new applications, from passive refrigeration cycles to semiconductor cooling. The primary heat transfer techniques associated with phase change heat transfer are pool boiling, flow boiling, and spray cooling. Of these techniques, spray
Probabilistic Risk Assessment (PRA) is a methodology consisting of techniques to assess the probability of failure or success of a system. In many modern technological systems, especially safety critical systems such as space systems, nuclear power plants, medical devices, defense systems, etc,
