RISAbsorption Spectra and Electron Vibration Coupling of Ti:Sapphire From First Principles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Firstprinciples calculations are performed to study the absorption spectra and electronvibration coupling of titaniumdoped sapphire (Ti:Al2O3). Geometry optimization shows a local structure relaxation after the doping of ...
Optimized Phonon Band Discretization Scheme for Efficiently Solving the Nongray Boltzmann Transport Equation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The phonon Boltzmann transport equation (BTE) is an important tool for studying the nanoscale thermal transport. Because phonons have a large spread in their properties, the nongray (i.e., considering different phonon ...
<i>HSPF</i> Simulation of Runoff and Sediment Loads in the Upper Changjiang River Basin, China
Publisher: American Society of Civil Engineers
Abstract: To evaluate the performance of a computer model simulating runoff and sediment load in the upper region of the Changjiang (Yangtze River) basin over a relatively short time interval, including examining the applicability ...
Design and Optimization of Thermoelectric Cooling System Under Natural Convection Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design method for the thermoelectric cooling system is improved in this work based on a graphical approach. It is used to select an appropriate thermoelectric cooler (TEC) and determine the value of optimum input current. ...
Daily Runoff Simulation by an Integrated Catchment Model in the Middle and Lower Regions of the Changjiang Basin, China
Publisher: American Society of Civil Engineers
Abstract: To simulate daily runoff in the middle and lower regions of the Changjiang (Yangtze River) basin, we used an integrated, spatially distributed model consisting of the Hydrological Simulation Program—FORTRAN (HSPF) and two ...
