Analysis of Differential Equations of Thermally Stimulated Currents in Semiconductors: Arbitrary Heating Profile

The thermally stimulated current (TSC) rate equations are solved for an arbitrary heating profile. The equations are analyzed for fast and slow retrapping regimes in the case when the sample is rapidly heated at a constant rate to the set temperature and held there until the current fully decays.

A Metrological Analysis of the Equations for Measuring Heat Energy and Heat-Carrier Loss in Hot-Water Supply Systems

Analytical formulas for the errors in measuring heat energy and heat-carrier loss in hot-water supply systems are obtained. It is shown that it is technically and economically inadvisable to use instrumental methods to calculate heat-carrier leakage in hot-water supply systems. Recommendations are made on the optimum organization of heat-energy calculations.

Estimates of Flaw Detectability in Welded Joints by X-ray Testing

The paper presents formulas for estimating detectability of three-dimensional and planar flaws of arbitrary dimensions, shapes, depths, and orientations in welded joints. Calculations and experimental data concerning the detectablity of flaws in welded joints by the X-ray method are discussed.
