this paper evaluates the real exchange rate fluctuations and uncertainties resulting from it, in the iranian economy. for this purpose, at first indirect effect of real exchange rate uncertainties on economic growth through foreign investment, private investment and exports are expressed, then the real exchange rate uncertainties and its relationship with economic growth and final pattern of in...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

The aim of this paper is to examine the concentration of wealth among the group of top wealth holders, defined as those with wealth in excess of a high cut off. The paper begins by considering the definition of this cut off, analogous to the definition of a poverty line at the other end of the distribution. It then considers what can be learned about the proportion classified as ‘rich’ and abou...

We begin the development of a theory of Banach spaces in the definable setting of o-minimal structures. We outline several results which develop the theory of compact embeddings for explicitly given function spaces. One aim is to explain the substantive underpinnings of an important observation used in the proof of the Reparameterization Theorem of Pila and Wilkie in [2]. We place this observat...

This paper provides a Fuzzy based decision support system (DSS) for risk analysis in E-tourism ( Electronic Tourism ) investment. In general term, E-tourism is the use of information and communication technology (ICT) in tourism which may allow operating tourism in least variable cost, least time and increased work efficiency. It is worth noting that there are many factors that affect the deve...

Predictability of financial time series (FTS) is a well-known dilemma. A typical approach to this problem is to apply a regression model, built on the historical data and then further extend it into the future. If however the goal for FTS prediction would be to support or even make investment decisions, prediction generated by regression-based models are inappropriate as on top of being uncerta...

BEA is studying proposals to change the treatment of insurance services in the national accounts. There are 5 proposed changes: investment income will be added as a supplement to the premiums paid by policyholders; investment income is to include interest, dividends and capital gains; a measure of expected investment income will be incorporated; a measure of expected claims will be incorporated...
