Opis:: The paper reviews the development of the 3C-SiC MOSFETs in a unique development project combining the material and device expertise of HAST (Hoya Advanced Semiconductor Technologies) and Acreo, respectively. The motivation for the development of the 3C-SiC MOSFETs and the summary of the results from the lateral and vertical devices with varying size from single cell to 3×3 mm2 large devices are reviewed. The vertical devices had hexagonal and square unit cell designs with 2 žm and 4 žm channel length. The p-body was aluminum implanted and the source was nitrogen or phosphorus implanted. Low temperature Ti/W contacts were evaluated.

Tytuł:: Labour Mobility of Migrants from CIS Countries in Russia

Opis:: Labour migration is discussed here in the context of the transformation of the Russian labour market. Particular attention is paid to the analysis of changes in the labour market and to the way these changes affect the structure of employment for migrant workers, their inclusion in local labour markets, and the prevalence of illegal and informal employment. Of central importance is the analysis of migrants’ vertical occupational mobility. It is concluded that the education, qualifications, and professional knowledge of migrants are not in demand in the Russian labour market; the typical path of migrants in the labour market is downward labour mobility – occupying a position that is worse than the one they previously held in their home country. Upward labour mobility is extremely rare and characteristic almost exclusively of unskilled workers.

Opis:: In this article, the authors propose and investigate a new concept of HAPS aerostat design in a modular form, which allows for sequential increasing or decreasing of the total volume, up to the desired size. In its initial form, the aerostat has relatively small dimensions but its central cylindrical part is multi-segmented and can be easily extended. The application of controllable construction couplings enables precise control of the aerostat expansion process and significantly improves its vertical mobility. The paper describes details of telescopic aerostat construction, presents a mathematical model of its vertical motion and investigates numerically two volume control strategies aimed at maximization of operation efficiency and minimization of operation cost. The results obtained reveal the main problems that have to be addressed and the factors that play a key role in design of such telescopic aerostats and control of their vertical mobility.
