Recent studies about Intrusion Detection Systems (IDS) performance reveal that the value of an IDS and its optimal operation point depend not only on the Hit and False alarm rates but also on costs (such as those associated with making incorrect decisions about detection) and the hostility of the operating environment. An adaptive multiagent IDS is proposed in this paper and it is evaluated acc...

The design of a problem solver for a particular problem depends on the problem type, the system resources, and the application requirements, as well as the specific problem instance. The difficulty in matching a solver to a problem can be ameliorated through the use of online adaptive control of solving. In this approach, the solver or problem representation selection and parameters are defined...

Integrated project management means that design and planning are interleaved with plan execution, allowing both the design and plan to be changed as necessary. This requires that the right eeects of change are propagated through the plan and design. When this is distributed among designers and planners, no one may have all of the information to perform such propagation and it is important to id...

Based on actual industrial project on which the Gerstner laboratory has collaborated, we present a multiple-level scheduling approach as a mean to efficiently apply agent-based planning systems in high-volume production environment. Brief description of efficient and reconfigurable high-level scheduler based on linear programming, as well as design elements of lowlevel agent-based planning are ...

metrumrg is an R package that facilitates workflow for the discipline of pharmacometrics. Support is provided for data preparation, modeling, simulation, diagnostics, and reporting. Existing tools and techniques are emphasized where available; original solutions are provided for otherwise unmet needs. In particular, metrumrg implements an R interface for the NONMEM(®) modeling software, optiona...

A review of admissions to cancer services at University Hospital Galway (UHG) was undertaken to assess the appropriateness of hospital usage. All cancer specialty patients admitted from 26-28 May 2009 were reviewed (n = 82). Chi square tests, Exact tests, and One-way ANOVA were utilised to analyse key issues emerging from the data. Fifty (61%) were classified as emergencies. Twenty three (67%) ...

The simulation and modeling of complex physical systems often involves many components because (i) the physical system itself has components of differing natures, (ii) parallel computing strategies require many (somewhat independent) components, and (iii) existing simulation software applies only to simpler geometrical shapes and physical situations. We discuss how agent based networks are appl...

This paper takes a first step towards defining a standard component-based open hypermedia system storage interface in the context of the Open Hypermedia System Working Group. The paper presents a proposal for the core set of services of such an interface. The existence of such an interface is one of the basic preconditions for interoperability at the middleware level in hypermedia systems. The ...

This paper presents a novel fuzzy-based intelligent architecture that aims to find relevant and important associations between embedded-agent based services that form Ambient Intelligent Environments (AIEs). The embedded agents are used in two ways; first they monitor the inhabitants of the AIE, learning their behaviours in an online, non-intrusive and life-long fashion with the aim of pre-empt...
