It is well known that Field Programmable Gate Arrays (FPGA) are good platforms for implementing embedded systems because of their configurable nature. However, the temperature FPGAs becoming a serious concern. Improvements in manufacturing technology led to increased logic density integrated circuits as higher clock frequencies. As increases, so do power density, which turn increases temperatur...

Net-shape liquid composite molding (LCM) processes for the manufacturing of composite structures involve the permeation of a reactive thermoset polymeric resin through complex, fiber woven preforms. The physical behavior during the processing thus involves coupled multi-physics phenomena consisting of mass, thermal and species transport. The flow process models based on conservation of mass are...

Organic soil horizons function as important controls on the thermal state of near-surface soil and permafrost in high-latitude ecosystems. The thermal conductivity of organic horizons is typically lower than mineral soils and is closely linked to moisture content, bulk density, and water phase. In this study, we examined the relationship between thermal conductivity and soil moisture for differ...

The most popular model of a device transient thermal impedance is of the form [1, 3] The transient thermal impedance Z(t) of the monolithic switched regulator LT1073 is investigated in the paper. A new method of measuring this thermal parameter of the device in its real operation conditions is proposed and the proper measuring set is described, too. The results of the Z(t) measurements of the d...

The present article deals with transient thermal stress calculation on a safety horizontal shell and tube condenser. This condenser is used in power plant for cooling of hot steam diverted from the turbine case its emergency shutdown. standard was provided according to EN 13445 steady regime. As consistent this calculation, an expansion joint must be shell. main aim describe detailed temperatur...
