Energies, Vol. 8, Pages 6451-6467: Extrapolation of Transport Properties and Figure of Merit of a Thermoelectric Material

26.06.2015 | Goldsmid, H. Julian; Sharp, Jeff, Energies, 2015

The accurate determination of the thermoelectric properties of a material becomes increasingly difficult as the temperature rises. However, it is the properties at elevated temperatures that are important if thermoelectric generator efficiency is to be improved. It is shown that the dimensionless ...

Energies, Vol. 8, Pages 6365-6381: An Experimental Investigation on the Combustion and Heat Release Characteristics of an Opposed-Piston Folded-Cranktrain Diesel Engine

25.06.2015 | Ma, Fukang ; Zhao, Changlu ; Zhang, Fujun ; Zhao, Zhenfeng ; Zhang, Zhenyu ; Xie, Zhaoyi ; Wang, Hao, Energies, 2015

In opposed-piston folded-cranktrain diesel engines, the relative movement rules of opposed-pistons, combustion chamber components and injector position are different from those of conventional diesel engines. The combustion and heat release characteristics of an opposed-piston folded-cranktrain ...

Sensors, Vol. 15, Pages 14981-15005: Observed Thermal Impacts of Wind Farms Over Northern Illinois

25.06.2015 | Slawsky, Lauren M.; Zhou, Liming ; Roy, Somnath Baidya; Xia, Geng ; Vuille, Mathias ; Harris, Ronald A., Sensors, 2015

This paper assesses impacts of three wind farms in northern Illinois using land surface temperature (LST) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments onboard the Terra and Aqua satellites for the period 2003–2013. Changes in LST between two periods (before and ...

Sensors, Vol. 15, Pages 14788-14808: Design of a Thermoacoustic Sensor for Low Intensity Ultrasound Measurements Based on an Artificial Neural Network

23.06.2015 | Xing, Jida ; Chen, Jie, Sensors, 2015

In therapeutic ultrasound applications, accurate ultrasound output intensities are crucial because the physiological effects of therapeutic ultrasound are very sensitive to the intensity and duration of these applications. Although radiation force balance is a benchmark technique for measuring ...

Energies, Vol. 8, Pages 6215-6229: Finite Time Analysis of a Tri-Generation Cycle

23.06.2015 | Agnew, Brian ; Walker, Sara ; Ng, Bobo ; Tam, Ivan C. K., Energies, 2015

A review of the literature indicates that current tri-generation cycles show low thermal performance, even when optimised for maximum useful output. This paper presents a Finite Time analysis of a tri-generation cycle that is based upon coupled power and refrigeration Carnot cycles. The analysis ...

Sustainability, Vol. 7, Pages 7942-7958: Optimum Fisheries Management under Climate Variability: Evidence from Artisanal Marine Fishing in Ghana

19.06.2015 | Akpalu, Wisdom ; Dasmani, Isaac ; Normanyo, Ametefee K., Sustainability, 2015

In most developing coastal countries, the artisanal fisheries sector is managed as a common pool resource. As a result, such fisheries are overcapitalized and overfished. In Ghana, in addition to anthropogenic factors, there is evidence of rising coastal temperature and its variance, which could ...
