BACKGROUND Recently, a novel single-switch access technology based on infrared thermography was proposed. The technology exploits the temperature differences between the inside and surrounding areas of the mouth as a switch trigger, thereby allowing voluntary switch activation upon mouth opening. However, for this technology to be clinically viable, it must be validated against a gold standard ...

With the continued increase in power dissipation and power density of high-performance microprocessors, as well as requirements for high-density packaging and lower device junction temperatures, improvements of electronic cooling technologies have been becoming strategically important in the challenge of advanced thermal solutions for achieving higher cooling efficiencies while meeting reliabil...

A hybrid Photovoltaic/Thermal (PV/T) solar system integrates photovoltaic and solar thermal technologies into one single solar energy device, with dual generation of electricity and heat energy. The aim of the present study is to evaluate the potential for introduction of the PV/T technology into Northern China. For this purpose, outdoor experiments were conducted on a prototype of a PV/T water...

For the continuous operation in another 20 or more years from aged thermal power generating units that have already been operated for 30 years, Fuji Electric has replaced a two-cylinder reheat type turbine with sophisticated single-cylinder reheat type turbine, were reused the existing foundation and nearly all the auxiliary machinery as counter-measures of life prolongation of the plant. By re...

In order to properly model the friction and wear of elastomer materials, it is essential to understand some specific mechanical and tribological features. Mechanical characteristics of elastomer materials are different from those of metals and other relatively hard materials. Elastomers can bear large deformations, the stress-strain curves are non-linear, time and temperature dependent. When th...

The 3-omega method is conventionally used for the measurement of thermal conductivity in solid samples. The present work includes the experimental characterization and proof-of-concept measurements of sensor concepts, based on the 3-omega method. It is shown that this method can be used to measure fouling layers with a thickness of 10 to 400 μm, to conduct the measurement of flow rates with a h...

Modern air vehicles face increasing internal heat loads that must be appropriately understood in design and managed in operation. This paper examines one solution to creating more efficient and effective thermal management systems (TMSs): vapor cycle systems (VCSs). VCSs are increasingly being investigated by aerospace government and industry as a means to provide much greater efficiency in mov...

Rapid firing processes are well known to allow improvements in solar cell contacts, particularly for the rear contact. Previous results characterizing the quality of a rear aluminum-alloyed back surface field have measured the effective surface recombination velocity, which depends not only on the material parameters of the back surface field, but also on the base doping. This paper shows that ...

The flow and heat transfer characteristics of a closed-loop cooling system with a mini-channel heat sink for thermal management of electronics is studied experimentally. The heat sink is designed with corrugated fins to improve its heat dissipation capability. The experiments are performed using variable coolant volumetric flow rates and input heating powers. The experimental results show a hig...
