  Information Society in European Union and Bulgaria – Situation and Trends in Information and Communication Technologies Usage

The European Union has long recognized the role of information and communication technologies (ICTs) as key factor to greater competitiveness and integration of business organizations of the continent into the global economy. Currently, the transition to the Information Society has no alternative. Matter of national choice of each Member State, including Bulgaria, is not whether to build such, but manner and forms of its realization. Development of Information Society is a cross-border and transnational process in which individual countries implement their national policies. The theme of this paper is to investigate legislation, condition and trends in European Information Society. The aim of the study is a comparative analysis of indicators characterizing the Information Society in Europe as a whole and Bulgaria in particular. An empirical data from the websites of Eurostat, National Statistical Institute and the survey with the participation of the author are used for achieving the objective.

The objective of this publication is to review the situation of Bulgarian economy during the world economic crisis from 1929 till 1933. The research employs empirical approach and comparative economic analysis. The effect of the crisis upon major sectors of Bulgarian economy, such as agriculture and industry, has been examined, as well as its impact on the state of domestic and foreign trade, the state finance and the circulation of currency. A conclusion has been made that owing to the economic policy which the government conducted at the time, Bulgarian economy performed relatively well during the economic crisis and succeeded in minimizing the negative consequences of the crisis.

  A Linear Matrix Inequality Method for Stochastic Model on Markov Jump Linear Systems

  We consider a special class of linear quadratic stochastic models on Markov jump linear system. The aim is to find the best control function for a model. The search of the control function passes trough the computation of the maximal solution to a system of the general discrete time Riccati equations. An effective method for finding the maximal ... We consider a special class of linear quadratic stochastic models on Markov jump linear system. The aim is to find the best control function for a model. The search of the control function passes trough the computation of the maximal solution to a system of the general discrete time Riccati equations. An effective method for finding the maximal solution is the method of a linear matrix inequality (a standard method). In this paper we present two new modifications of the method of a linear matrix inequality. The numerical experiments for comparing the computational characteristics of the modified methods and the standard method are executed. The numerical experiments show the effectiveness of new methods to the standard method.
