Figure 1. (Panel A) 12-lead ECG depicting high degree right bundle branch block (see text for details). (Panel B) 12-lead ECG depicting the “Chiale” maneuver Right apical ventricular pacing during with timed A-V intervals in the fused QRS complexes. Black arrows show classic type 1 Brugada ECG pattern. Upon cessation of pacing, high-degree right bundle branch block reappears (white arrows). ECG...

The role of the solar energy as a natural source for synthesis electric heatersis discussedin this article. work famous scientists on development field using devices based in heat supply systems is presented. In addition, you will get acquainted with most popular and probably unfamiliar heaters, their types, modes operation. You also learn about process making heaters imported to date energy. W...

This paper reviews the stability, heat transfer efficiency and photothermal conversion optimization studies of solid-liquid phase change materials applied to water heaters. Suggestions prospects were proposed. The study shows that PCMs are mostly filled in tank, thermal storage devices or solar collector heater system with paraffin wax, addition can significantly improve performance. Further in...

High temperature is one of the limiting factors and major concerns in 3D-chip integration. In this paper we use a 3D test chip (WIDEIO DRAM on top of a logic die) equipped with temperature sensors and heaters to explore thermal effects. We correlated real temperature measurements with the power dissipated by the heaters using model learning techniques. The resulting compact thermal model is abl...

A local Spanish company that produces electric heaters needs an energy saving device to be integrated with the heaters. It was proven that a hybrid artificial intelligent systems (HAIS) could afford the energy saving reasonably, even though some improvements must be introduced. One of the critical elements in the process of designing an energy saving system is the thermodynamical modelling of t...
