This paper discusses methods for generating or approximating the Pareto set of multiobjective optimization problems by solving a sequence of constrained single-objective problems. The necessity of determining the constraint value a priori is shown to be a serious drawback of the original epsilon-constraint method. We therefore propose a new, adaptive scheme to generate appropriate constraint va...

Molecular-dynamics algorithms for systems interacting through discrete or “hard” potentials are fundamentally different to the methods for continuous or “soft” potential systems. Although many software packages have been developed for continuous potential systems, software for discrete potential systems based on event-driven algorithms are relatively scarce and fairly specialized. We present DY...

policy capacity focuses on the managerial and organizational abilities to inform policy decisions with sound research and analysis, and facilitate policy implementation with operational efficiency. it stems from a view of the policy process that is rational and positivistic, in which optimal policy choices can be identified, selected, and implemented with objectivity. by itself, however, policy...

introduction: efficient use of information systems in provision of health services is very important for achieving efficiency, effectiveness and service quality. in this study the various aspects of clinical information systems implementation and estimate of one of main users' knowledge about these systems in hospitals was investigated. methods: this study was conducted in two-stages: in the fi...

As the capabilities of mobile phones are increasing and they are able to consume different type of multimedia contents, it is important to provide an efficient content sharing solution for them. Since people usually store their content on their personal computer, we need architecture for content sharing which supports mobiles and personal computers as well. In this paper we propose an innovativ...

The paper introduces a multi-deme, memetic global optimization strategy Hierarchic memetic Strategy (HMS) especially wellsuited to the solution of a class of parametric inverse problems. This strategy develops dynamically a tree of dependent populations (demes) searching with the various accuracy growing from the root to the leaves. The search accuracy is associated with the accuracy of solving...

the market for carbon dioxide rights emerged as one of the tools applicable to the implementation of the measures adopted by the kyoto protocol to combat climate change. in this paper we analyze the case of spain, because their peculiar administrative division into seventeen autonomous communities, it is relevant to a detailed study of emissions and allowances of the industries that make up ...
