Solving a dynamic optimization problem means that the obtained results depend explicitly on time as a parameter. There are two major branches in which dynamic optimization occurs: (i) in dynamic programming and optimal control, and (ii) in dynamic fitness landscapes and evolutionary computation. In both fields, solving such problems is established practice while at the same time special and adv...

The aim of RWebServices is to facilitate exposing R functions as effective Java-based web or grid services. The application uses existing technologies in web and grid services, XML, as well as new and existing inter-system interfaces between R and other languages. We briefly review the state of art of these research areas here, with an emphasis on applications related to RWebServices.

Value at Risk measures the worst loss to be expected of a portfolio over a given time horizon at a given confidence level. Calculation of VaR frequently involves estimating the volatility of return processes and quantiles of standardized returns. In this paper, several semiparametric techniques are introduced to estimate the volatilities . In addition, both parametric and nonparametric techniqu...

This article reviews on-shell methods for analytic computation of loop amplitudes, emphasizing techniques based on unitarity cuts. Unitarity techniques are formulated generally but have been especially useful for calculating one-loop amplitudes in massless theories such as Yang-Mills theory, QCD, and QED. Loop amplitudes in gauge theories: modern analytic approaches 2

This work was undertaken in order to develop methods and techniques for evaluating systematically and comprehensively protective action strategies in the case of a nuclear or radiation emergency. This was done in a way that the concerns and issues of all key players related to decisions on protective actions could be aggregated into decision-making transparently and in an equal manner. An appro...

The study mainly aims at looking into the disparities in beneficiary’s socio-economic status between areas without implementation of forestry plans and where had initially been available even though they have recently terminated as well. Babol Roud plan is located Lafoor forest area County, Mazandaran Province, Northeast Iran. This research was divided three steps: first all, by making use Coch...

Rigorous engineering of safety-critical CyberPhysical Systems (CPS) requires integration of heterogeneous modeling methods from different disciplines. It is often necessary to view this integration from the perspective of analyses – algorithms that read and change models. Although such analytic integration supports formal contract-based verification of model evolution, it suffers from the limit...
