AN ECONOMETRICAL MODEL FOR CALCULATING THE ROMANIAN GROSS DOMESTIC PRODUCT

This article analyzes the possibility of determining the Romanian Gross Domestic Product on the basis of a linear model, based on macroeconomic indicators such as unemployment, inflation, exchange rate. The proposed solution allows forecasting the Gross Domestic Product for the following period of time based on equation determined from the model in order to develop scenarios for improving the macroeconomic situation of Romania. The article also can be a starting point in the field of strategic investments, both at macro and micro level. Any foreign investor, before starting a business in another country, calculated and also made predictions about the economic situation of that country, in order not to lose the investment made.regression, GDP, inflation, unemployment, forecast

CLASSIFICATION OF EUROPEAN UNION COUNTRIES FROM DATA MINING POINT OF VIEW, USING SAS ENTERPRISE GUIDE

With the development of computers and the increasing the amount of data it appeared the need of identifying new acquaintances, unknown until that moment in a relatively short time. The term of data mining involves the analysis of data from different views (aspects) in order to extract the knowledge to use them further in the foundation of decisions at microeconomic or macroeconomic levels. In this article we apply data analysis techniques such as principal component analysis and cluster analysis in order to group the countries of the European Union based on the financial indicators registered at the end of 2009 year.classification, cluster, data mining, European Union, financial indicators

Romania’s competitive advantage within the European Union area

The central idea of the paper emphasizes Romania’s competitive advantages in the EU and there are two analysis levels herein: the correct identification of Romania’s competitive advantages and the oportunities to value them. The paper aims at achieving a competitiveness analysis of the Romanian economy during 2006-2009. The Romanian economy’s integration within the European Union does not only mean a mere inclusion or accession into/to the Community, but it also represents the belonging to a strongly competitive area. Since the Union has mainly aimed at becoming the most competitive economy at world level, Romania has to face a double challenge: redefining its competitiveness and reducing the current gaps between its economy and the average level of the main EU social and economic indices. Redefining competitiveness is actually redefining competitiveness determiners. Reaching the convergence goal is based on the Romanian economy’s sustainable competitive advantages. The essential concern is their proper identification, as they are the result of a strategic vision. Taking account of these principles, Romania’s EU accession is acquiring new traits. Is there a competitiveness gain or is there a certain loss right from the moment of the accession

THE INFLUENCE OF RATING INDICATORS IN MACROECONOMIC DECISIONS

On the basis of major macroeconomic decisions are the internal indicators calculated by different institutions and also the rating indicators calculated by the foreign rating institutions. Based on these indicators a country has a lower or a greater level of risk for future investments. Not always a higher risk level corresponds to a higher level of income. There are many situations when we have to know the potential risks in order to take a wise decision. In the paper I presented the calculation methodologies of the country rating for the main agencies and I made a comparison between various levels of sovereign ratings for European Union countries.rating methodologies, Fitch, Moody’s, Standard & Poors, Coface, risk, decision

THE INFLUENCE OF JURIDICAL REGULATIONS UPON TOURIST TOWN-PLANNING

Urban tourism, if correctly planned, developed and managed, may create advantages and benefits both to urban communities and overall society. By systematically implementing planning based on intelligent management and town-planning regulations complying with the organizing and long-lasting growth requirements of towns, local and national communities, benefits can be maximized, whereas troubles minimized. Town planning should pursue the juridical requirements of the legislation in force, based on a flexible, comprehensive, integrated and ecological approach, being implementable on the principles of keeping the tourist sector’s long life.town planning, town-planning law, town plans, tourist town planning.

A versatile micro-scale silicon sensor/actuator with low power consumption

We designed a CMOS compatible hot-surface silicon device operating at a power down to sub-µW. It has a pillarshaped structure with a nano-size (10-100 nm) conductive link between the electrodes separated by a SiO2 layer. The device is capable of maintaining a µm-size hot-surface area of several hundred degrees centigrade due to non-radiative recombination of carriers in a thin (13 nm) poly silicon surface layer. Such a device can be used as a light source, a heat source, as well as a sensitive detector of light and heat. As a direct application, we demonstrate the feasibility to perform as an adsorption-desorption sensor, and as a unit for activating chemisorption/decomposition (i.e. micro-reactor)

ARTIFICIAL NEURAL NETWORKS AND THEIR APPLICATIONS IN BUSINESS

In modern software implementations of artificial neural networks the approach inspired by biology has more or less been abandoned for a more practical approach based on statistics and signal processing. In some of these systems, neural networks, or parts of neural networks (such as artificial neurons), are used as components in larger systems that combine both adaptive and non-adaptive elements. There are many problems which are solved with neural networks, especially in business and economic domains.neuron, neural networks, artificial intelligence, feed-forward neural networks, classification

A pillar-shaped antifuse-based silicon chemical sensor and actuator

We designed a silicon-processing compatible, simple, and cheap device operating at a power down to sub- W. It has a pillar-shaped structure with a nanoscopic (10–100 nm in size) conductive link (the so-called antifuse) created between two electrodes separated by a SiO2 layer. The device exhibits a diode-like behavior due to the depletion effects in the mono-silicon pillar. The device is capable of maintaining a microscopic hot-surface area of several hundreds degrees centigrade. The size of the hot area and its temperature can be manipulated by the sign of the applied bias.\ud Two different heat-generation mechanisms (i.e., dissipation at a resistor and a non-radiative recombination of carriers) are proposed and modelled. Such a device can be used as a heat source, as a light source, and as a sensitive detector of light and heat. In this paper, we describe thermo-electrical properties of the fabricated devices and demonstrate their feasibility to perform as gas-, adsorption-, desorption sensors, and as units for activating chemisorption/decomposition of gaseous precursors, i.e., micro-reactors.\u
