Distributed lag models are of importance when it is believed that a covariate at time t, say Xt, causes an impact in the mean value of the response variable, Yt. Moreover, it is believed that the effect of X on Y persists for a period and decays to zero as time passes by. There are in the literature many different models that deal with this kind of situation. This paper aims to review some of t...

Group key establishment is an important mechanism to construct a common session key for group communications. Conventional group key establishment protocols use an on-line trusted key generation center (KGC) to transfer the group key for each participant in each session. However, this approach requires that a trusted server be set up, and it incurs communication overhead costs. In this article,...

Currently, stock price forecasting is carried out using either time series prediction methods or trend classifiers. The trend classifiers are designed to predict the behaviour of stock price’s movement. Recently, soft computing methods, like support vector machines, have shown promising results in the realization of this particular problem. In this paper, we apply several prototype generation c...

In recent years, carbon emission markets have become liquid and promising markets within the European Union emissions trading scheme (EU ETS). In order to fit and forecast futures price for CO2 emissions allowances, we propose a new N-factor affine term structure model for CO2 futures price and estimate parameters in the new affine model by using the Kalman filter technique. Our empirical resul...

We set up a two level supply chain model which consists of one manufacturer and two retailers in this paper. Necessities as the main research object, we develop the nonlinear demand function of products which is more related to the reality. In order to increase the performance of whole supply chain in the decentralized decision, we introduce revenue sharing mechanism in this paper. Through nume...

The Network Of Workstations (NOWs) is the trend for distributed computing, and the costeffectiveness of networking system is one of the key issues for NOWs. The IEEE 1394 bus can be a cost-effective solution for linking a network of computers, in this paper, we tested the performance of IEEE 1394 on the Linux system, and discussed how to improve the IEEE 1394 performance towards cluster computi...

This mathematical model allows calculation of Unit Commitment (hereinafter UC), providing for compliance with all technical limitations in the equipment state and electricity regime parameters to ensure the minimization of the total cost of electric power generation, as determined on the basis of notifications wholesale market participants on the composition and parameters of the generating equ...

This work addresses two key topics in the field of energy harvesting and wireless power transfer. The first is the optimum signal design for improved RF-DC conversion efficiency in rectifier circuits by using time varying envelope signals. The second is the design of rectifiers that present reduced sensitivity to input power and output load variations by introducing resistance compression netwo...

abstract:the paper begins by noting that proposals involving significant developments in the regional tradearchitecture are being developed within regional processes that in some cases are simultaneouslypursuing other dimensions of regional economic integration: monetary and financial cooperation inthe case of asean + 3, and the establishment of a common market in the case of asean. at leastthr...

abstract background: transcranial doppler ultrasonography results have not been previously studied in among iranian sickle cell anemia patients. the present study was performed to evaluate the pattern of intracranial flow velocities among iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial art...
