Using a bio-economic model, H2OBeef, that includes traditionally considered parameters associated with running a beef feedlot but also incorporates aspects associated with water, changes that can alter water consumption and or price are examined. The results indicate that when water does not...

An experimental platform was designed and built for testing the thermal performance of a water/steam cavity receiver. The experimental platform was utilized to investigate the start-up performance and operation characteristics of the receiver. The electrical heating mode was chosen to simulate...

Analytical expressions have been developed to calculate the temperature dependent electrical efficiency (ηm) and the effect of water flow on the performance of a-Si thin film photovoltaic (PV) modules. The calculated results have been validated by experimental investigations on commercially...

Die internationale Beachtung der Forschungsergebnisse in der Wirtschaftsinformatik hat in den letzten Jahren an Bedeutung gewonnen. Dabei wird dem kritischen Diskurs ein wachsender Stellenwert eingeräumt. Hier gilt es, den wissenschaftlichen Nachwuchs in der Konzeption und Durchführung der...

Due to the dominance of Open Source Software (OSS) in IT and the IT enabled services industry, various stakeholders are keen to understand the OSS evolution process. Several studies have been conducted in the past in this regard. There are various techniques used in the past for understanding...

A simplification for the variable sorptivity infiltration equation of Poulovassilis et al. (1989) is proposed. The resulting equation has three parameters S <Subscript>x</Subscript>, c and K <Subscript>0</Subscript>. From these, S <Subscript>x</Subscript> and c are considered as fitting parameters and K <Subscript>0</Subscript> as a physical one. The new empirical infiltration equation...</subscript></subscript></subscript></subscript>

Exact numerical solution of the electrostatic disordered potential problem is carried out for four fully discretized three-dimensional experimental reconstructions of sedimentary rocks. The measured effective macroscopic dielectric constants and electrical conductivities are compared with...
