The role of clouds in modifying the earth’s radiation balance is well recognized as a key uncertainty in predicting any potential future climate change. This statement is true whether the climate change of interest is caused by changing emissions of greenhouse gases and sulfates, deforestation, ozone depletion, volcanic eruptions, or changes in the solar constant. This paper presents an overvie...

Among numerical sequences, the Fibonacci numbers have achieved a kind of celebrity status with such fabulous properties, it is no wonder that the Fibonacci numbers stand out as a kind of super sequence. Fibonacci numbers have been studied in many different forms for centuries and the literature on the subject is consequently, incredibly vast. The Fibonacci sequence has been generalized in a num...

The effect of solder joint fabrication on the thermal properties IGBTs soldered onto glass-epoxy substrate (FR4) was investigated. Glass-epoxy substrates with a thickness 1.50 mm, covered 35 ?m thick Cu layer, were used. A surface finish prepared from hot air leveling (HAL) Sn99Cu0.7Ag0.3 layer 1 ÷ 40 ?m. IGBT transistors NGB8207BN SACX0307 (Sn99Ag0.3Cu0.7) paste. samples in different soldering...
