There have been very few direct applications of experimental techniques in macroeconomics for two main reasons. First, macroeconomics is about the in­ teraction between markets, and it is not easy to design an elegant treatment that gets at the essence of how a national economy functions. Second, there is a vestigial prejudice that favors econometrics over putatively unorthodox em­ pirical appr...

The condensed matter nuclear reactions (CMNR) are thought to happen for trapped H(D) particles within some chemical (electro-magnetic) potential well with finite life time. As the life time is much longer than the collision time of two-body interaction of free particles, CMNR reaction rates are significantly (on the order of 19-20 in magnitude) enhanced if we compare with estimated reactions ra...

This paper presents a video coding scheme for very low bit rate applications The coding approach relies on active mes hes and can be viewed as a particular case of region based coding The active mesh is used to e ciently represent and code the various regions of the scene and the motion infor mation The variation of the mesh topology as well as the strategy for coding the synthesis error are de...

portfolio theory assumes that investors accept risk. this means thatin the equal rate of return on the two assets, the assets were chosenthat have a lower risk level. modern portfolio theory is accepted byinvestors who believe that they are not cope with the market. sothey keep many different types of securities in order to access theoptimum efficiency rate that is close to the rate of return o...

A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used to calculate momentum transfer rate constant for Cl- with trans-dichloroethylene and para-difluorobenzene. Theoretical results ...

In this paper, we obtain the Rényi entropy rate for irreducible-aperiodic Markov chains with countable state space, using the theory of countable nonnegative matrices. We also obtain the bound for the rate of Rényi entropy of an irreducible Markov chain. Finally, we show that the bound for the Rényi entropy rate is the Shannon entropy rate.

the purpose of this research is investigation of application of the arbitrage pricing theory and effect of unanticipated changes in a set of macroeconomic variables such as inflation rate, money supply, exchange rate, oil price, term structure and industrial production on expected security return in tehran stock exchange. in this research, data are analyzed quarterly for the period of 1997-2008...
