The article presents graphs of absorption thermal radiation as a function the mass absorbing carbon dioxide per unit illuminated area. Experimental research was preceded by an analysis simplified model absorption, paying attention to phenomenon saturation. results experimental were compared with theoretical ones and discrepancies interpreted. Based on conclusions, suggestions made regarding imp...

The results of measurements the current dependences thermal resistance junction-case LEDs various types and manufacturers are presented. It is determined that increases with increasing current, for many samples there a noticeable break in dependence at currents close to nominal one. has been experimentally shown steepness can be used as diagnostic parameter makes it possible estimate degree tem...

The level of satisfaction with an environment differs among individuals, which may be caused by social, psychological and physical factors. One of the environmental factors affecting physical and mental satisfaction, is the thermal condition of space. In recent years, the importance of thermal comfort has been accentuated due to the climate change and global warming, increasing the number of st...
