In this letter, it is proposed to use TerraSAR-X data for analysis and estimation of soil surface texture. Our study is based on experimental campaigns carried out over a semiarid area in North Africa. Simultaneously with TerraSAR-X radar acquisitions, ground measurements (texture, soil moisture, and roughness) were made on different test fields. A strong(More)
Photovoltaic electricity generation is one alternative to use of renewable energy source. Efficiency of photovoltaic systems can be upgraded by operating photovoltaic panel at its optimum power point by using maximum power point tracking. Getting maximum power from the solar panels needed DC-DC converters by using the algorithm of MPPT. This paper presents(More)
Charging systems of battery electric current from the PV source with pulse charging technique is done to distribute high electric current to the battery without causing damage to the functionality and performance of the battery through a process to vary the pulse width. Techniques vary the pulse width is done by adjusting the duration of the charging(More)
