This paper presents a novel technique to eliminate non-simultaneous triggering e ects in nger-type ESD protection transistor using SiGe heterojunction buried layer structures. It is con rmed that lower snapback voltage and maximum lattice temperature are obtainable in the new structure based on device simulation. As a result, current localization and lattice overheating of a nger-type protectio...

Polymer coatings with periodic topographic patterns, repeating over millimetre length scales, can be created from lateral flows in an aqueous dispersion of colloidal particles. The flow is driven by differences in evaporation rate across the wet film surface created by IR radiative heating through a shadow mask. This new process, which we call IR radiation-assisted evaporative lithography (IRAE...

Identification and prediction of clogging behavior in heating, ventilation, air conditioning (HVAC) filters is crucial to avoid issues such as system overheating, energy waste, lower indoor quality, etc. Researchers are focusing more on the particle loading characteristics a filter medium laboratory environment under steady-state conditions, fixed concentrations, area porosity, dust feed volume...

The paper describes different influences of magnetic and electromagnetic shielding on stray flux distribution in power transformers. application shields the reduction high temperature spots transformer tank is studied detail by using a 3D model for coupled electromagnetic-thermal calculation. analysis models with various shapes dimensions show which factors are most important hot tank. Proposed...

It is well known that the construction sector one of main sectors responsible for energy consumption in current global scenario. Thus, buildings’ software become essential tools achieving savings. Climate and its implications building performance are a critical threat. Hence, aim this study to evaluate climatic conditions urban suburban areas Rome, estimating incidence Urban Heat Island (UHI) p...

Thermal protection in marine electrical propulsion motors is commonly implemented by installing temperature sensors on the windings of motor. An alarm issued once reaches limit, while motor shuts down trip limit reached. Field experience shows that this scheme some cases insufficient, as may already be damaged before reaching limit. In paper, we develop a machine learning algorithm to predict o...

Abstract Concrete mix design is the methodology for mixing binder, aggregate and water to achieve required physical, mechanical, thermal properties. In particular, physical properties depend on volume fraction of each element in concrete recipe. this study we considered cement mortar, complying with ASTM C105, as reference binder silica sand aggregate. The mortar was denser high conductivity co...
