We develop a Markov decision process (MDP) model to examine aerial military medical evacuation (MEDEVAC) dispatch policies in a combat environment. The problem of deciding which aeromedical asset to dispatch to each service request is complicated by the threat conditions at the service locations and the priority class of each casualty event. We assume requests for MEDEVAC support arrive sequent...

A novel methodology for the economic evaluation of hydrogen production and storage for a mixed wind-nuclear power plant considering some new aspects such as residual heat and oxygen utilization is applied in this work. This analysis is completed in the context of a Hydrogen Economy and competitive electricity markets. The simulation of the operation of a combined nuclear-wind-hydrogen system is...

BACKGROUND Trauma still stands atop of the list of emergencies. Transfer of these patients via Emergency Medical Services (EMS) dispatch is critical with regard to importance of timing. This aspect has achieved greater importance due to population increase and telephone triage. OBJECTIVES We aimed to decrease unnecessary Emergency Medical Services (EMS) missions via a computer program designe...

INTRODUCTION In The Netherlands there is no consensus about criteria for cancelling helicopter emergency medical services (HEMS) dispatches. This study assessed the ability of the primary HEMS dispatch criteria to identify major trauma patients. The predictive power of other early prehospital parameters was evaluated to design a safe triage model for HEMS dispatch cancellations. METHODS All t...

A historical prospective mortality study was conducted on a cohort of 34 156 male members of a heavy construction equipment operators union with potential exposure to diesel exhaust emissions. This cohort comprised all individuals who were members of the International Union of Operating Engineers, Locals 3 and 3A, for at least one year between 1 January 1964 and 31 December 1978. The mortality ...

A novel usability evaluation technique, Ontological Sketch Modelling (OSM), was applied to the analysis of systems used within a complex work setting, namely emergency medical dispatch. OSM focuses on the structure of the domain in question and the devices which are applied to that domain, in order to reason about the quality of fit between the two. This analysis shows how OSM can be used to id...

In this paper particle swarm optimization (PSO) algorithm is proposed to optimize Combined Economic emission Dispatch Problem (CEEDP)of thermal units. Combined Economic emission Dispatch Problem (CEEDP is used to minimize both total fuel cost of generation and the emission of toxic gases of the thermal generating units simultaneously while satisfying the load demand and constraints of the syste...

This paper presents an efficient Water Evaporation Optimization algorithm (WEO) is proposed to solve a Dynamic Economic Dispatch problem (DED). The dynamic dispatch problem differs from the static economic dispatch problem by incorporating generator spinning reserve, ramp rate limits, and valve point loading and transmission losses. The proposed water evaporation optimization algorithm is based...

data types, inheritance, dynamic binding and garbage collection. bstract data types provide encapsulation and inheritance eases reuse. Both promote extensibility and modi ability. These two requirements seem widely accepted and we will not address them further. ynamic binding of functions to function names is one key to the exibility and extensibility of object-oriented languages. It allows new...

The mobile agent approach is suitable for deploying large-scale parallel processing over distributed hosts. However, if the number of mobile agents is very large and the dispatch is processed in a serial way, it can become a bottleneck that impacts the efficiency as a whole. In this paper, we first briefly present a mobile agent based framework for Internet marketplaces enabling parallel proces...
