High emitter profile
WebIn order to obtain a high current amplification factor, it is important in transistors that the ratio of the injected minority carrier current over the total emitter current, γ, be close to unity, or that the quantity 1-γ, called the injection deficit, be as small as possible. It is shown that the injection deficit of an emitter can be decreased by several orders of magnitude if the … Web1 de mai. de 2007 · Reviews by the California Inspection/Maintenance Review Committee showed the high-emitter profile to be inefficient and in need of improvement. In this study, using in-use vehicle emissions data from California’s statewide smog check program, we specified a new multinomial logit model designed to improve the screening efficiency for …

Web21 de mai. de 2024 · Since the positron emitter activity profile is not directly proportional to the dose distribution, until today only its comparison to a prediction of the PET profile allows for treatment verification. Usually, this prediction is obtained from time-consuming Monte Carlo simulations of high computational effort, which impacts the clinical workflow. Webour knowledge, this leads to the first emitter developed so far that is capable of addressing the three main green- house gases, CO 2 ,H 2 O, and CH 4 , in the 2 μm region.
