The reaction phenomena of CPOM (catalytic partial oxidation of methane) in a Swiss-roll reactor are studied numerically where a rhodium-based catalyst bed is embedded at the center of the reactor. CO2 is added into the feed gas and excess enthalpy recovery is performed to evaluate their...

A three-dimensional (3-D), transient, nonisothermal model of all-vanadium redox flow batteries (VRFBs) is developed by rigorously accounting for the electrochemical reactions of four types of vanadium ions (V2+, V3+, VO2+, and VO2+) and the resulting mass and heat transport processes. Particular...

We consider nonlinear waves driven by curvature in the presence of periodically distributed obstacles. When the obstacles are small, Matano et al. (2006) proved rigorously that the propagation speed of a wave mainly depends on the opening angle of the obstacles. In this paper we first explain...

This paper presents one kind of new car-following model (mean memory model, simplified as MMM) by introducing driver sensory memory (sensory buffer) term into the original optimal velocity (OV) function by Bando et al. (1995, 1998). The main improvement is that MMM can avoid the disadvantage of...

The requirements for improvement in the energy efficiency of buildings, mandatory in many EU countries, entail a high level of thermal insulation of the building envelope. In recent years, super-insulation materials with very low thermal conductivity have been developed. These materials provide...

In 2008, the Utah Retirement System experienced a negative return of almost 25 percent on its portfolio. This resulted in an underfunding of the pension system. In 2010 the Utah legislature reformed state pension participation, placing all new employees hired after mid-2011 in a new hybrid...

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...

The Earth-Air Heat Exchanger (EAHE) is a device used to improve the thermal condition of built environments, allowing the reduction of electrical energy consumption of traditional air conditioner systems. Fundamentally, its operational principle is based on fluid mechanics and heat transfer,...

This study presents a novel performance evaluation algorithm for horizontal GCHPs (ground coupled heat pump systems) that considers rainfall infiltration. The influence of rainfall infiltration on the thermal characteristics of shallow trenches is examined using infiltration analyses, and then a...

We extend the model by DeGrauwe and Grimaldi (2006, EER) by currency transaction taxes. This model explains the exchange rate behavior by the interaction of heterogeneous traders who display either trend chasing behavior or rely on a return of the exchange rate back to its arbitrage free...
