Based on the I-V curves of a photovoltaic (PV) module, a novel and simple model is proposed in this paper to predict the PV module performance for engineering applications. Five parameters are introduced in this model to account for the complex dependence of the PV module performance upon...

We examine the economic consequences of the recent adoption of SFAS 123(R) in the United States. Consistent with the conjectures of prior research, our results show that the removal of favorable accounting treatment for stock options post SFAS 123(R) results in a switch from stock options to...

Press reports indicate that the Environmental Protection Agency may significantly reduce ethanol mandates to levels that can easily be met. To gain insight into what this decision implies about the price of corn we use a new model of the corn and RIN markets to project corn and ethanol prices...

A rational expectations competitive storage model for U.S. corn and RIN (Renewable Identification Numbers) markets is built to study the impacts of different ethanol policy scenarios. The model considers corn use for ethanol, storage and all other uses in each period, accounting for two random...

An electrolyte-supported hybrid direct carbon fuel cell (DCFC) was used to evaluate the performance of different carbon fuels in this study. The direct carbon fuel cell consists of a samarium doped ceria (SDC) electrolyte, a Ni/SDC anode and a Ba0.5Sr0.5Co0.8Fe0.2O3−δ cathode. Three types of...

Affected by natural and human-induced factors, cultural heritage sites and their surroundings face threats of structural instability and land displacement. Accurate and rapid identification of the key areas facing existing or potential deformation risks is essential for the conservation and...

In order to study the microscopic physical mechanisms of roughness surfaces exhibiting the anomalous scaling behavior, the Wolf–Villain model in 1+1 and 2+1 dimensions is investigated by the kinetic Monte-Carlo simulation on long time and large length scale (the growth time and the system size...

The growth of the modified Family model and the Etching model on the Sierpinski carpet is studied by means of numerical simulations. The evolving interface of the aggregates is described by the well-established Family–Vicsek dynamic scaling approach. The results of the modified Family model...
