fluctuate between different RASS scores, but can also transition between delirium, stupor, and coma. Stupor and Coma: Definitions and their Epidemiology in the Emergency Department Stupor and coma occurs in 5% to 9% of older ED patients and when present, are considered to be medical emergencies that require immediate evaluation.9,10 These 102 Han & Wilber Fig. 1.

results, a series of experimental results of oxidation of a unidirectional SiC/Ti matrix MMC are presented. The measured oxide thicknesses at different times and temperatures are used to calibrate and validate the model under development. While the present paper deals only with the oxidation problem, the coupled oxidationthermomech~mical problem, and especially the influence of oxidation on fatigue life of MMCs, will be presented in a future communication. 1.

However, there is a very broad spectrum of PHEV designs with greatly-varying costs and benefits. In particular, battery costs, fuel costs, vehicle performance attributes and driving habits greatly-influence the relative value of PHEVs. This paper presents a comparison of the costs (vehicle purchase costs and energy costs) and benefits (reduced petroleum consumption) of PHEVs relative to hybrid-electric and conventional vehicles. A detailed simulation model is used to predict petroleum…

output voltage and includes switches and the output filter. This report addresses the buck-boost power stage only and does not cover control circuits. Detailed steady-state and small-signal analysis of the buck-boost power stage operating in continuous and discontinuous mode is presented. Variations in the standard buck-boost power stage and a discussion of power stage component requirements are included.

fuel or in blends with petroleum-based diesel fuels. The concept itself may appear simple, but that appearance is deceiving since the use of biodiesel is fraught with numerous technical issues. Accordingly, many researchers around the world have dealt with these issues and in many cases devised unique solutions. This book is an attempt to summarize these issues, to explain how they have been dealt with, and to present data and technical information. Countless legislative and regulatory…

importance. We make no apology for adding one more to the succession of English grammars. In the first place, though fairly brief synopses are common enough, there have been very few attempts at so comprehensive a coverage as is offered in the present work. Fewer still in terms of synchronic description. And none at all so comprehensive or in such depth has been produced within an English-speaking country. Moreover, our Grammar aims at this comprehensiveness and depth in treating…

torque over the operating range. This form of control is relatively inexpensive and easy to implement. Feedback from the rotor is not utilized and the rotor is assumed to follow the rotating flux generated in the stator, with a certain amount of slip present depending upon the load. To drive an AC induction motor, the 3-phase inverter bridge is driven by a microcontroller’s PWM outputs, as shown in Figure 2. By changing the PWM duty cycles in a regular manner, the PWM outputs are…
