Abstract A novel constraint to prevent local overheating is presented for use in topology optimization (TO). The very basis the Additive Manufacturing (AM) process physics. AM enables fabrication of highly complex topologically optimized designs. However, a major concern especially metal processes leading part failure, poor surface finish, lack dimensional precision, and inferior mechanical pro...

We use a comprehensive database of 121 countries over the 1971-2016 period to study how macroeconomic factors drive carbon (carbon-dioxide) emissions. For this purpose, dynamic panel regressions are estimated. Carbon emissions rise with economic development, manufacturing activity, urbanization and increasingly growth. In electricity generation, coal, lesser degree oil, is associated higher emi...

Rising global temperatures and more frequent heatwaves due to climate change have led a growing body of research increased policy focus on how protect against the adverse effects heat. In cold temperate Europe, dwellings traditionally been designed for protection rather than heat mitigation. There is, therefore, need understand mechanisms through which indoor overheating can occur, its occupant...

The switching phenomenon observed in electronically conductive glasses corresponds to a sudden decrease in electrical resistance of the sample when a large electric field is applied. A simple electrothermal model is developed which takes into account only a Joule effect overheating of the material. In a temperature range below the glass transition temperature, Tg, the switching is reversible. O...

Faults and damage in oil-filled power transformers has a devastating effect on the overall reliability of electrical power systems. Several factors, especially electrical and thermal stresses age the transformer and subject them to incipient faults. These faults, if left undetected will cause deterioration and eventually lead to failure of the transformer [1]. The presence of faults such as arc...
