Local averaging and differentiating of spec
نویسنده
چکیده
Local frequency and time averaging and differentiating operators, using three neighboring points of critical-band timefrequency plane, are used to process the plane prior to its use in TRAP-based ASR. In that way, five alternative TRAP-based ASR systems (the original one and the time/frequency integrated/differentiated ones)are created. We show that the frequency differentiating operator improves performance of the TRAP-based ASR.

Averaging Level Control to Reduce Off-Spec Material in a Continuous Pharmaceutical Pilot Plant
The judicious use of buffering capacity is important in the development of future continuous pharmaceutical manufacturing processes. The potential benefits are investigated of using optimal-averaging level control for tanks that have buffering capacity for a section of a continuous pharmaceutical pilot plant involving two crystallizers, a combined filtration and washing stage and a buffer tank....

Background and Aim: Local anesthesia plays an important role in dentistry. Although hypersensitivity reactions to local anesthetic drugs are rare,but they are more common in dental cartridge components. This study reports a rare case of hypersensitivity to components of local anesthesia cartridge. Case Report: A 61-year-old female patient referred to The Medical Council to complain the dentist ...

Progressive collapse is a kind of failure in which whole or large part of a structure collapse when a local damage occurs and distributes to other parts. Many researchers focus on the column removal analysis and study of the structure behavior under effect of gravity loads, so these investigations are mostly carried out on the tall building. Earthquake inspections indicate structural element ca...
متن کاملAdaptive Decision Fusion in Detection Networks
In a detection network, the final decision is made by fusing the decisions from local detectors. The objective of that decision is to minimize the final error probability. To implement and optimal fusion rule, the performance of each detector, i.e. its probability of false alarm and its probability of missed detection as well as the a priori probabilities of the hypotheses, must be known. How...
