An approach to the pre-runtime design of normative systems for problem-solving multi-agent systems (MAS) is suggested. A key element of this approach is to employ evolutionary mechanisms to evolve efficient normative systems. To illustrate, a genetic algoritm is used in the process of designing a normative system for an example MAS based on the Dalmas architecture for normregulated MAS. It is d...

The paper presents an experimental toolkit for modeling and solving Cuuy constraint satisfaction problems (FCSPs) called JFSolver. JFSolver is a Java based library developed as an extension of a erisp constraint programming library to provide an enhanced functionality for handling fuzzy constraints including fuzzy constraint specification, propagation and search mechanisms. JFSolver comprises a...

Alzheimer's disease (AD) is the most common form of neurodegenerative disorders. Memory loss in an alert person and impairment in the function of language, attention, perception, judgment or problem solving can occur in patients with AD. However, there are some medications in order to delay the debilitating aspects of the disease; but unfortunately, scientists could not found approaches to cure...

Selection hyper-heuristic methodologies explore the space of heuristics which in turn explore the space of candidate solutions for solving hard computational problems. This study investigates the performance of approaches based on a framework that hybridizes selection hyper-heuristics and population based incremental learning (PBIL), mixing offline and online learning mechanisms for solving dyn...

The aim of the present work is to prepare an adsorption package to simulate adsorption / desorption operation for both single and multi-component systems in an isothermal condition by different mechanisms such as; local adsorption theory and mass transfer resistance (rigorous and approximated methods). Different mass transfer resistance mechanisms of pore, solid and bidispersed diffusion, t...

The Santa Claus problem provides an excellent exercise in concurrent programming and can be used to show the simplicity or complexity of solving problems using a particular set of concurrency mechanisms and offers a comparison of these mechanisms. Shared-memory constructs, message passing constructs, and process oriented constructs will be used in various programming languages to solve the Sant...

As more business has been shifted online, the database is a vital part of many critical systems. Many researches have been done on keeping database safe. While, however, admittedly, no defense mechanism could prevent every attack and some attack will unavoidably succeed. Therefore, the idea of attack resilient database system is proposed. However, how well the proposed solution works and why th...

The author comments on an article by Helmes and colleagues (this issue, pp. 000-000) that studied defense mechanisms related to alexithymia. What these authors observed is theoretically meaningful, and a distinct strength of this study is that the results are replicated in three independent samples. The study is also exemplary for two typical drawbacks- only student samples and self-report meas...

Laggera pterodonta displays different phenotypes in its natural habitat but expresses a uniform phenotype with large, broad leaves and fewer secondary metabolites when grown under optimal conditions. The production of six furoeudesmanes is only induced when L. pterodonta encounters stresses, conferring host resistance against a broad spectrum of plant invaders.
