Abstract
The paper reports on terbium-related photo-, cathode-, and under X-ray luminescence in yttrium alumina composites Y3Al5O12 and YAlO3. The composite Y3Al5O12 was fabricated using the sol-gel method in a form of powder followed by its pressing in a tablet. The composite YAlO3 was formed in the pores of anodic alumina film grown on silicon wafer. The possibility of application both of the method for high resolution X-ray film convertor is discussed.

Abstract
The software to simulate radiation resistance of MOSFET transistors, the basic elements of CMOS integrated circuits, is presented. The software performs visualization and analysis of volt-ampere characteristics of p - and n -channel transistors, extraction of «radiation sensitive» SPICE parameters and modeling of their variations with an ionizing radiation. The degradation of MOSFET transistors of the 1554LN1 microcircuit is investigated for gamma Co60 irradiation.

Abstract
An efficient algorithm for evaluating the interval of solutions stability of opened and closed linear assignment problems based on a review of the results of optimization iterations is proposed. Economical one-step transition to the nearest vertex of the polytope of problem one for all the edges of the optimal perfect matching is almost an order of magnitude reduces the computational complexity of evaluating the stability of the current optimal solution.

Abstract
Comprehensive analyses of different scaling technique to be used for high education service quality estimation are provided. The most well-known scaling techniques have been described with simple illustrating example. The Likert scaling approach has been pointed out as the more suitable approach for high education service quality estimation.
