We present a computational model for predicting the net solar energy conversion efficiency of a single-junction solar cell backed by a solid-state photon upconversion nanostructure. We model the upconversion process using a series of kinetic rate equations to calculate equilibrium populations. We determine the upconversion quantum efficiency (UQE) of the proposed device as a function of intentionally...
Smart Grid technologies hold the promise of being able to solve many of the problems currently facing in the electric power industry. However, the large scale deployment of these new technologies has been limited due to an inability to accurately model their effects or to quantify their potential benefits. GridLAB-D is a new open source power system modeling and simulation environment developed by...
This paper presents a method for reconstruction of entire three-dimensional objects based on principles of the rotational stereo. The experimental system, which has three degrees of freedom (two for translation and one for rotation), uses an accurate stage to make all areas of the object surface visible. It only needs one camera to capture images and thus reduces the implementation cost. The object...
In this study, we designed a Cell-to-ECG forward model to simulate ischemia condition from cell level, and then defined five different ischemia locations including inferior, anterior, septal, lateral, and apex on an actual 3-D heart geometry from CT images. For simulating the early ischemia, the ion channels are adjusted through concentration and conductance. The extent of ischemia is defined with...
