In the last years, there is an increasing interest for enhanced method assessing and monitoring level of global horizontal irradiance (GHI) in photovoltaic (PV) systems, fostered by massive deployment this energy. Thermopile or photodiode pyranometers provide point measurements, which may not be adequate cases when areal information important (as PV network large plants monitoring). The use All...

The monitoring of processor temperature is crucial to increase its efficiency. One the novel approaches use information not only about CPU (Central Processing Unit) thermal state, but also changing environmental conditions. additional difference sensor monitor changes in environment necessary. dedicated for active heat sink, often used inside laptops, was designed, fabricated and investigated. ...

This article proposes a new calorimetry-based measurement method to measure absolute microwave power obtained through dc substituted from 110 170 GHz (WG 29, WR 6/7, or D-band) using custom-designed thin-film sensor. complements traditional microcalorimetry techniques used provide traceability for in this band while diversifying the potential applications and accessibility such traceability. Th...
