Plasma flow velocity fluctuations have been directly measured in the high temperature magnetically confined plasma in the Madison Symmetric Torus (MST) Reversed-Field Pinch (RFP) [R. N. Dexter et al., Fusion Tech. 19, 131 (1991)]. These measurements show that the flow velocity fluctuations are correlated with magnetic field fluctuations such that the electromotive force v ̃ H B ̃ approximately ba...

I represent the Business Rules Group (BRG) on the governing board of the Business Rules Team, the consortium that has submitted "Business Semantics of Business Vocabulary and Business Rules” (SBVR) in response to the OMG's RFP for "Business Semantics of Business Rules". So, it should be no surprise that my main focus on rules is at the business end rules that guide what people do in businesses ...

This paper deals with a retrial queueing system with a finite number of homogeneous sources of calls and a single non-reliable server, which means that the server is subject to random breakdowns depending on whether it is busy or idle. The failure of the server may block or unblock the systems’s operations and the service of the interrupted request may be resumed or the call can be transmitted ...

Interdealer trading in the European sovereign bond market is characterized by low spreads and high liquidity. This paper examines whether the dealer-customer segment of the market also benefits from low spreads. Customers are smaller banks and buy-side financial institutions who request quotes from primary dealers. They generally do not enjoy access to the interdealer trading platform. Surprisi...

This paper defines the fundamental concepts, key elements, and semantics of a metamodel that is being proposed as a response to the OMG's RFP for a Business Process Definition Metamodel [BPDM]. It also introduces notations that allow to view a process model at varying levels of detail, while maintaining consistency with the underlying model and semantics. A formal definition of the metamodel an...

We consider a seller who faces several buyers and lacks access to an institution to credibly close a sale. If buyers anticipate that the seller may negotiate further, they will prefer to wait before making their best and final offers. This in turn induces the seller to bargain at length with buyers, even if doing so is costly. When the seller’s cost of soliciting another round of offers is eith...

Many scheduling problems reside in uncertain and dynamic environments – tasks have a nonzero probability of failure and may need to be rescheduled. In these cases, an optimized solution for a short-term time horizon may have a detrimental impact over a broader time scale. We examine a scheduling domain in which time and energy on a phased array radar system is allocated to track objects in orbi...

Knowledge Management represents a crucial component of corporations’ efforts to gain competitive advantage from targeted re-use of knowledge assets. Companies that provide consulting services depend heavily on developing, selling, and applying ideas. They need to organize and structure intellectual property for efficient and effective re-use. In this paper, we discuss the RFP Responder, a proto...

Engineering designers, industrial designers and architects have different design cultures in their approaches to solving design problems. Traditionally engineering and architectural designers have used a structured approach based upon a ‘concept, embodiment, detail and prototype’ model to design their product. However, industrial designers have tended to use a less structured approach based on ...
