̈C This paper presents a concept of transmission of electrical energy from a power source to an electrical load without physical conducting medium. It is based on the well known principle of resonant inductive coupling and, in particular, resonant evanescent coupling [1] .This well known physics leads trivially to the result of energy efficient midrange wireless energy-exchange. We establish tha...

The smooth threshold autoregressive (STAR) model is by far the most successful model in explaining the well-known two PPP puzzles. The nonlinearity in STAR captures the nature of vast transaction costs in trade, sunk costs in (foreign) investment, and hetergeneity in agents. In this paper, we use a variant of STAR, the Exponential STAR (ESTAR), to study the exchange rate dynamics in China durin...

This paper examines empirically the tourism impact on the long-run economic growth of Greece by using the causality analysis among real gross domestic product, real effective exchange rate and international tourism earnings. A multivariate autoregressive VAR model is applied for the examined period 1960:Ι – 2000:IV. The results of cointegration analysis suggested that there is one cointegrated ...

background: in spite of the great progress in assisted reproductive techniques ( art) and although good quality embryos are transferred pregnancy rates have remained around 30%-35% due to low implantation rates. objective: the aim of this study was to assess and compare the effects of administrating indomethacin or hyoscine suppositories prior to embryo transfer on the pregnancy rate in art cyc...

The surface oxygen exchange kinetics of bismuth oxide stabilized with 25 mol% erbia (BE25) has been studied in the temperature and pO2 ranges 773–1,023 K and 0.1– 0.95 atm, respectively, using pulse-response O–O isotope exchange measurements. The results indicate that BE25 exhibits a comparatively high exchange rate, which is rate determined by the dissociative adsorption of oxygen. Defect chem...

The exchange rate regime in Iran is practically fixed. The Central Bank of Iran (CBI) has committed itself to trying to bring about a particular exchange rate regime to meet two important targets: 1. Sustaining competitiveness of the economy, 2. Acquiring the share of foreign reserves in monetary base in a predetermined level. Since 2001 the share of foreign reserves in monetary base has i...

making capital and investment is the main driving forces of economic development. based on the investment sensitivity to the changes of some of macro-economic variables and risk and uncertainty, the present study evaluated the effective factors on investment in private sector in iran during 1980-2007. at first, the uncertainty variables of real informal exchange rate, nominal interest rate and ...
