Prevalence and characteristics of driving difficulties in Operation Iraqi Freedom/Operation Enduring Freedom combat returnees.
We studied the prevalence and characteristics of self-reported driving difficulties and examined their association with traumatic brain injury (TBI) and/or posttraumatic stress disorder (PTSD) in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) veterans who were seen at a Department of Veterans Affairs outpatient polytrauma clinic. In this study, we used a brief driving questionnair...
متن کاملDecomposition of Rings under the Circle Operation
We consider rings S, not necessarily with 1, and develop a decomposition theory for submonoids and subgroups of (S, ◦) where the circle operation ◦ is defined by x ◦ y = x + y − xy. Decompositions are expressed in terms of internal semidirect, reverse semidirect and general products, which may be realised externally in terms of naturally occurring representations and antirepresentations. The th...
متن کاملOptimizing an Industrial Grinding Operation Under Uncertainty
Handling uncertainties for parameters in nonlinear constraints using chance constrained programming (CCP) is not as straight forward as its linear counterparts. A simulation based CCP approach which can be thought as an alternative to handle such a situation, has been adopted in this work while solving a multi-objective optimization problem of an industrial grinding operation under various para...
متن کاملMicrogrids Operation And Control Under Emergency Conditions
Under normal conditions, the MicroGrid operates interconnected with the upstream medium voltage network. However, scheduled or forced isolation can take place. In such conditions, the MicroGrid must have the ability to operate stably and autonomously, requiring the development of suitable control strategies in order to enable MicroGrid islanded operation. The MicroGrid power sources can also be...
متن کاملOperation of Distributed Generation Under Stochastic Prices
The ongoing deregulation of electricity industries worldwide is providing incentives for microgrids, entities that use small-scale distributed generation (DG) and combined heat and power (CHP) applications to meet local energy loads, to evolve independently of the traditional centralised grid in order to provide greater flexibility and energy efficiency to end-use consumers. We examine the impa...
