We have discussed the thermal sensing capability under a constant current level and versus voltage ( I–V) traces by measuring temperature of high series resistance Pt/ n-GaP/Al/Ti Schottky structures in 100−320 K range. The R s values 35 Ω 4.50 × 10 3 kΩ for device been determined from I–V at 320 100 K, respectively. V–T) curves are expected to give straight line each level. However, V–T deviat...

New R-band observations of 21 local field RR Lyrae variable stars are used to explore the reliability of minimum light (V − R) colors as a tool for measuring interstellar reddening. For each star, R-band intensity mean magnitudes and light amplitudes are presented. Corresponding V -band light curves from the literature are supplemented with the new photometry, and (V − R) colors at minimum ligh...

Harvested energy makes it possible to deploy sensing devices long-term with minimal required upkeep. However, as devices shrink, unpredictable power supplies make it difficult for system designers to anticipate the behavior of these devices. Ekho is tool that records and emulates energy harvesting conditions in order to enable accurate and repeatable testing of these sensing devices. Ekho uses ...

Abstract: This paper proposes a new analysis method for photovoltaic (PV) modules. The main objectives are to obtain the resistance parameters of PV modules by adjusting I-V equation and voltage equation of diode and to find the relationship between resistance parameters and power. Firstly, values of serial resistance and parallel resistance at maximum power point are concluded. Secondly, the c...

Equivalent circuit models of solar cells are important for understanding the behavior photovoltaic systems under different weather conditions. They provide an equation F(V,I)=0 that expresses correspondence between voltage V and current I a cell can deliver. The performance cell, and, therefore, parameters F, depend on cell’s temperature incoming light’s energy angle. One would like to simulate...

The effect of coupling on the intensity-response functions for full field and for slit stimuli was studied by comparing the shapes of the curves obtained from several strongly coupled red cones of turtle with that of one very weakly coupled cone. The full field V-log I curves could be fitted by a Michaelis-Menten relationship, regardless of the strength of the coupling. For the weakly coupled c...
