an analytical equation of state by song and mason is developed to calculate the pvt properties ofmercury. the equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. there exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...
by using a model of development, called developmental state, which appeared during the history of development in east asia region, the current essay tries to present a review on possibility of iran’s transition to economic development. it is supposed that the ground is prepared for iran’s transition to development through effective state intervention in economy. unlimited access of iran to a ve...
this study tried to explore disciplinary variations of web blurbs across soft and hard knowledge fields on the one hand, and to illustrate how academic publishers exploit interactional metadiscourse devices in move structure of their blurbs on the other.
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
conclusion we believed that the nonspecific clinical and laboratory finding of the present case and also the rarity of disease in our area especially in immunocompetent patients made his diagnosis confounding. patient we report an immunocompetent 43 years old iranian man who was in excellent health status until 3 weeksbefore hospitalization when he developed headache. he experienced a 5-week de...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
Allocation of measurement devices is a necessity of distribution system which is an application of state estimation. In this paper, the problem of active and reactive measurement devices is modeling using a multi-objective method. The objectives of the problem are to minimize the use of measurement devices, increase in state estimation output, improve the state estimation quality and reduce cos...
A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...
We study the correlation complexity (or equivalently, the communication complexity) of generating a bipartite quantum state ρ. When ρ is a pure state, we completely characterize the complexity for approximately generating ρ by a corresponding approximate rank, closing a gap left in Ambainis, Schulman, Ta-Shma, Vazirani and Wigderson (SIAM Journal on Computing, 32(6):1570-1585, 2003). When ρ is ...
