in this paper, based on error correction model by using panel data, an empirical analysis of demand for international reserves for 16 islamic countries is investigated. besides addressing conventional issues, the model explicitly incorporates the impact of expected export revenues and the impact of the exchange rate system on reserve demand. the results reveal that, short run money market diseq...

investigation of soil properties like cation exchange capacity (cec) plays important roles in study of environmental reaserches as the spatial and temporal variability of this property have been led to development of indirect methods in estimation of this soil characteristic. pedotransfer functions (ptfs) provide an alternative by estimating soil parameters from more readily available soil data...

One of the most significant discussion and challenges propounded in the macroeconomics is the effects of fluctuations of exchange rate on the macroeconomic variables (production, employment, inflation and … etc).In this direction, the important and noticeable point is the factors which lead to fluctuations in the exchange rate which, from amongst these factors as an example, is fluctuations in ...

There have been several efforts in the literature to extract as much information as possible from the financial networks. Most of the research has been concerned about the hierarchical structures, clustering, topology and also the behavior of the market network; but not a notable work on the network filtration exists. This paper proposes a stock market filtering model using the correlation - ba...

This work describes the modeling and control of a proposed actuation system that is capable of pressurizing a chamber volume via the catalytic decomposition of a liquid monopropellant controlled by a binary on/off propellant valve. Two design configurations of the actuation system are presented and common portions of both are energetically modeled. The parameters of the resulting dynamic model ...

Information exchange in policy networks is usually attributed to preference similarity, influence reputation, social trust and institutional actor roles. We suggest that political opportunity structures and transaction costs play another crucial role and estimate a rich statistical network model on tie formation in the German toxic chemicals policy domain. The results indicate that the effect o...

the objective of this study is to provide a partial equilibrium analysis of the effects of tariff and exchange rate policy on the net exports with the particular emphasis on the selected economic sectors. the eight economic sectors in the model are agriculture; food, beverages and tobacco; textiles; wood; chemicals; construction; paper and miselaneous which contains metallic and non merallic pr...

In the paper “Stronger Security of Authenticated Key Exchange” [11, 12], a new security model for authenticated key exchange protocols (eCK) is proposed. The new model is suggested to be at least as strong as previous models for key exchange protocols, such as the CK model [5, 10]. The model includes a new notion of an EphemeralKeyReveal adversary query, which is claimed in e. g. [11, 17, 18] t...

In this paper, we investigate the security model for authenticated key exchange protocols. We observe that there is further room to extend the latest enhanced Canetti-Krawczyk (eCK) model. We further enhance the freshness definition for the threepass authenticated key exchange protocols such that our new definition gives the adversary more capabilities. We point out that the three-pass authenti...
