DEVELOPING IT&C DOMAIN PREMISE OF SUSTAINABLE DEVELOPMENT IN ROMANIA
In the information society, economic fields with advanced technology represent the main vector of development in consonance with the sustainable development of human society. The paper examines the evolution of economic sectors with high technology as the main component of the information society in Romania compared to EU countries, both in terms of number of companies and also production value, value added at factor cost, gross operating surplus, etc.. It is used to analyze statistical data from the years 2008-2012 from Eurostat databases, Undata and the National Institute of Statistics.
STATISTICAL ANALYSIS OF THE EVOLUTION OF RESEARCH-DEVELOPMENT ACTIVITY IN SOUTH-WEST OLTENIA DEVELOPMENT REGION IN 2002-2010
The importance of research and development activity is undeniable in supporting economic competitiveness on medium and long term. The evolution of research development activities differs from one region to another, Southwest Oltenia Region recorded a low level of them. The evolution of the structure of employees in research and development in the South-West Oltenia Region on counties highlights that in Dolj county is the largest part of the employees in this activity. Places 2 and 3 were alternating counties Valcea and Gorj with a number of employees between 126 and 190 people in Gorj County and between 185 and 219 people in Valcea County. In terms of expenditure for research-development activity, South-West Oltenia Region ranks sixth among the regions, and in the region Dolj holds the firs position.
A new method of near field analysis
The problem of the accurate determination of the total electromagnetic field produced by a current distribution on a circular disc type aperture is examined. For comparison of the near and Fresnel region solutions, an exact Maxwellian integral is used as the starting point. Aperture and space coordinates are separated by the use of Bessel function addition theorems, allowing the field to be expressed as a sum of terms containing radial and angular integrals. The radial integrals involve only the disc (aperture) distribution and coordinates while the angular integrals involve only the elevation angle. The distance from origin appears implicitly in the series coefficients. These integrals are suitable for high speed computations and have been evaluated for a number of cases. The results are compared with the small angle and general Fresnel formula values for various observation angles, distances from the aperture, and aperture distributions.
