Object-oriented systems must implement message dispatch efficiently in order not to penalize the object-oriented programming style. We characterize the performance of most previously published dispatch techniques for both staticallyand dynamically-typed languages with both single and multiple inheritance. Hardware organization (in particular, branch latency and superscalar instruction issue) si...

The taxi dispatch problem involves assigning taxis to callers waiting at different locations. A dispatch system currently in use by a major taxi company divides the city (in which the system operates) into regional dispatch areas. Each area has fixed designated adjacent areas hand-coded by human experts. When a local area does not have vacant cabs, the system chooses an adjacent area to search....

BACKGROUND In countries where a single public emergency telephone number is not in operation, different emergency telephone numbers corresponding to multiple dispatch centres (police, fire, emergency medical service) may create confusion for the population about the most appropriate service to call. In particular, out-of-hospital cardiac arrest (OHCA) requires a prompt and effective response. W...

OBJECTIVE This study aimed to elucidate the actual activities conducted by public health nurses during their dispatch and their health status during and after dispatch to the three prefectures most severely affected by the Great East Japan Earthquake. SAMPLE A survey request was sent to a total of 2,237 facilities. Of these, 778 facilities returned questionnaires from dispatched public health...

In this paper, Hopfield Neural Network (HNN) and Lagrange Multiplier (LM) solutions to economic dispatch (ED), NOx emission dispatch (EmD), and economic-emission dispatch (EED) of a sample system consisting of six thermal generators are presented. Transmission losses are included. The results of HNN are compared with the results of LM.

This thesis investigates the application of marginal cost based spot pricing techniques to the short run coordination of decentralised, and potentially competitive, electricity markets. A Dispatch Based Pricing philosophy is proposed which requires that the dispatcher of a power system determine spot prices which are consistent with both the observed power system dispatch and the offers and bid...

this paper proposes per unit coding for combined economic emission load dispatch problem. in the proposed coding, it is possible to apply the percent effects of elements in any number and with high accuracy in objective function. in the proposed per unit coding, each function is transformed into per unit form based on its own maximum value and has a value from 0 to 1. in this paper, particle sw...

Continuing demands for high degrees of Instruction Level Parallelism (ILP) require large dispatch queues (or centralized reservation stations) in modern superscalar microprocessors. However, such large dispatch queues are inevitably accompanied by high circuit complexity which would correspondingly limit the pipeline clock rates. In other words, increasing the size of the dispatch queue ultimat...
