Evaluation of the Performances of Electrically Heated Clothing
… these problems, a slim garment with a built-in heating element could be useful. The heat input power and heating efficiency are the two most important parameters for a piece of heated clothing. The input power determines how much heat can be released from the whole clothing system, while the …

Evaluation of Residential Real Estate Energy-Rating Systems in Germany, and their Applicability to the United States
Energy efficiency has become an increasingly important topic as economies globally race to combat climate change. Real estate is a major driver of global emissions, however also a key potential area for emissions reductions. In Germany, residential real estate has been identified as a major source …

Multiwavelength Study of Photodissociation Regions and a Near -Infrared Imager
… the illuminating star has little effect on the heating efficiency of the PDR, which agrees with the color temperature model of Spaans, Tielens, van Dishoeck & Bakes. Chapter 4 describes the construction and operation of the Near Infrared Imager (NIRIM), which was commissioned at the Mt. Laguna …

Mathematical modeling of D.C. electric arc furnace operations
… of the furnace (e.g., heat transfer to the bath, heating efficiency, mixing times in the bath, etc). Predictions from the arc model show that all the arc characteristics are strongly coupled and that the arc physics is governed by the expansion of the arc. From a parametric study it was found that …

Cryomilling and Spark Plasma Sintering of 2024 Aluminium Alloy
… current flows directly on the powders and a high heating efficiency is offered. It is known that Al powders are hardly sinterable due to oxide layer on their surface. This layer has to be broken in order to form a solid neck between the particles. SPS has been used to produce nanostructured Al and …
