This paper presents CROS, a Contingency Response multi-agent system for Oil Spill situations. The system uses the Case-Based Reasoning methodology to generate predictions to determine the probability of finding oil slicks in certain areas of the ocean. CBR uses past information to generate new solutions to the current problem. The system employs a SOA-basedmulti-agent architecture so that thema...

In this paper we present an overview of contingency tables, provide an introduction to the problems of almost uniform sampling and approximate counting, and show recent results achieved through the use of Markov chains. We focus specifically on contingency tables with two rows, since as of this time little progress has been made in achieving reasonable bounds on arbitrarily sized contingency ta...

In the area of power system planning and operation, contingency analysis plays an important role. In the present days, on-line security assessment is done by contingency ranking, with the help of various computer software, incorporating iterative method like Newton Raphson power flow for obtaining the magnitudes of different parameters. The motive of contingency ranking is to create a short lis...

Although practitioners have begun to implement Green IT into their companies, the governance of sustainable information systems varies significantly. Only little has been done to explain these differences in Green IT governance. Building upon contingency theory and IT governance, we develop a contingency model for Green IT governance which demonstrates the fit between contingencies and the comp...

Dynamic environments represent a quite complex domain, where the information available changes continuously. In this paper, a contingency response system for dynamic environments called MACSDE is presented. The explained system allows the introduction of information, the monitoring of the process and the generation of predictions. The system makes use of a CaseBased Reasoning system which gener...

Contingency management is a highly effective treatment for substance use and related disorders. However, few psychiatrists are familiar with this intervention or its application to a range of patient behaviours. This paper describes contingency management and evidence of its efficacy for reducing drug use. It then details areas in which contingency management interventions can be applied in the...

Hilbert-style axiomatic systems are presented for versions of the modal logics KΣ, where Σ ⊆ {D,4,5}, with non-contingency as the sole modal primitive. The classes of frames characterized by the axioms of these systems are shown to be first-order definable, though not equal to the classes of serial, transitive, or euclidean frames. The canonical frame of the non-contingency logic of any logic c...

believe that a hallmark of good science is that it can be explained concisely in simple, jargon-free terms to a non-scientist. Karl von Frisch, the famous Nobel laureate who championed the study of honeybee behaviour, is said to have commented that a good scientific seminar should be organized in three parts. The first part should consist of material that the audience already knows, so that the...

Many applications of autonomous agents require groups to work in tight coordination. To be dependable, these groups must plan, carry out and adapt their activities in a way that is robust to failure and uncertainty. Previous work has produced contingent plan execution systems that provide robustness during their plan extraction phase, by choosing between functionally redundant methods, and duri...

Prior research showed that mere instructions about the contingency between a conditioned stimulus (CS) and an unconditioned stimulus (US) can generate fear reactions to the CS. Little is known, however, about the extent to which actual CS-US contingency experience adds anything beyond the effect of contingency instructions. Our results extend previous studies on this topic in that it included f...
