Arc plasma torches are the primary components of various industrial thermal plasma processes involving plasma spraying, metal cutting and welding, thermal plasma CVD, metal melting and remelting, waste treatment and gas production. They are relatively simple devices whose operation implies intricate thermal, chemical, electrical, and fluid dynamics phenomena. Modeling may be used as a means to ...

Thermal signatures of buried land mines depend on a complex combination of environmental conditions, soil properties, and properties and burial depth of the land mine. Due to the complex nature of the problem most modeling and experimental efforts to understand thermal signatures of land mines have focused on the effects of one or a few variables. Of these variables, the effect of wind speed ha...

3D stacked architectures are getting increasingly attractive as they improve yield, reduce interconnect power and latency, and enable integrating layers manufactured with different technologies on the same chip. However, 3D integration results in higher temperatures following the increase in thermal resistances. This chapter discusses thermal modeling and management of 3D systems with a particu...

A new approach for the electro-thermal modeling of LDMOSFETs for power-amplifier design that bypasses pulsed-IVs and pulsed-RF measurements is presented in this paper. The existence of low-frequency dispersion in LDMOSFETs is demonstrated by comparing pulsed IVs with iso-thermal IVs. The modeling technique uses iso-thermal IV and microwave measurements to obtain the temperature dependence of sm...

The life time of a component is defined by the reliability demands place on it due to its operating environment and operation conditions. To evaluate the necessarily thermal / power cycle stability of a power semiconductor module in a hybrid electrical vehicle (HEV), a vehicle driving cycle profile is used to calculate the thermal reliability requirements. The calculations are based on power lo...

The detection of thermal insulation failures in buildings in operation responds to the challenge of improving building energy efficiency. This multidisciplinary study presents a novel four-step soft computing knowledge identification model called IKBIS to perform thermal insulation failure detection. It proposes the use of Exploratory Projection Pursuit methods to study the relation between inp...

Hot tips are used either for characterizing nanostructures by using Scanning Thermal Microscopes or for local heating to assist data writing. The tip-sample thermal interaction involves conduction at solid-solid contact as well as conduction through the ambient gas and through the water meniscus. We analyze those three heat transfer modes with experimental data and modeling. We conclude that th...

Rapid energy modeling is a streamlined process to capture, model, and analyze building energy performance. Timely assessment of existing building energy performance helps owners and facility managers to identify potential areas for better retrofit, and meet environmental and economic goals. Despite the increasing attention to building energy performance, the current process of energy data colle...
