Although the processing power of uniprocessor sys tems is signi cantly increasing every year there is a never ending quest for peak performance The so called grand challenges in computing require more computing power than a single uniprocessor machine can ever o er Recent advances in parallel processing however has brought the solution of grand challenges into reach What is usually neglected wh...

Assume k (k 2) populations are given. The associated independent random variables have continuous distribution functions with an unknown location parameter. The statistical selection goal is to select a non-empty subset which contains the best population, that is the population with largest value of the location parameter with conndence level P (k ?1 < P < 1). Some distributional results for su...

We analyze the interactions between internal and external control mechanisms in a framework in which the board selects the CEO and then decides whether to retain or dismiss him after observing a signal regarding his ability. The novel aspect of our paper is that we consider both the hiring and the ...ring of the CEO by the board. The type of board is de...ned by its ability to select a good CEO...

This paper attempts to develop a theory of su ciency in the setting of non-commutative algebras parallel to the ideas in classical mathematical statistics. Su ciency of a coarse-graining means that all information is extracted about the mutual relation of a given family of states. In the paper su cient coarse-grainings are characterized in several equivalent ways and the non-commutative analogu...

We consider large double auctions with private values. Values need be neither symmetric nor independent. Multiple units may be owned or desired. Participation may be stochastic. We introduce a very mild notion of “a little independence.” We prove that all non-trivial equilibria which satisfy this notion are asymptotically e¢cient. For any ® > 0; ine¢ciency disappears at rate 1=n2¡®.

Mobile agent systems incur resource overheads as they acquire and maintain knowledge about their network environment. This paper presents a technique that, for a speci c set of cases, optimises network resource consumption through dynamic selection of agent interaction protocols. This process is made possible through learning on the part of static knowledge agents, which can then predict the li...

Although most people believe that planners that delay step-ordering decisions as long as possible are more eecient than those that manipulate totally ordered sequences of actions, this intuition has received little formal justii-cation or empirical validation. In this paper we do both, characterizing the types of domains that ooer performance diierentiation and the features that distinguish the...

This paper examine the efficiency of microfinance institutions (MFIs) in WAEMU (West African Economic and Monetary Union). Using DEA (Data Envelopment Analysis), we calculate technical scores a sample 80 savings credit cooperatives 2014. We find higher levels for social efficacy than financial efficiency. The comparative analysis effectiveness according to country origin institution shows that ...
