Opis:
In the article are presented the results of the irradiance obtained by using Dialux program. The calculations were made for two cases of simple geometries, which are known according to analysis to determine the average values of geometrical configuration factor. A comparison of the results obtained and confirmed their compliance. Dialux program for some systems which certain some conditions and simplifying assumptions described in section 1 can be used, and radiometric parameters obtained do not differ from those of analytically calculation. The program allows a adopt for radiating surface nolambertian radiation intensity distribution. This expands the applicability of the calculation to the areas where analytical calculations are time consuming and complicated. Confirmation are set out in section 6 of the calculations for the heating system of real more complicated situations.

Opis:
Influence of light sources in various contrast obstacle recognition is presented in the article. Station of measurement was built and the survey on observers were conducted. Surveys were conducted with two values of adaptive luminance and two values of test luminance. These values corresponds with the road lighting luminance. Tested objects were squares with various contrast luminance placed on the white background. Gained results were analyzed and may be basis to the future laboratory and outdoor surveys.

Opis:
Laboratory tests of temperature control systems are often time consuming processes. This condition results from large time constants of real electrothermal devices. One of possibility of reduction the time value required for tests lays from utility of analogue models. Such models are characterized by possibility to unrestricted formation of time scales of voltage and current wave shapes. According to this advantage, temperature process in real device can be significantly accelerated. In the article the universal Beuken model, coupled with control and recording system implemented in PLC controller was presented. The model can be used in selection of optimal parameters of temperature controller process. The ability of transient characteristics recording and comparing provides ease selection of proper regulator and location of temperature sensor, adapted to specific solution.
