Simulation model used as design improvement decision tool for warehouse material flow
… by an Automated Storage and Retrieval System (ASRS) which consists of a network of conveyors, vertical lifts, and Selection and Retrieval Machines (SRMs). The ASRS system is not performing to the designed put-away and shipping rates, thus limiting the DC's overall performance during peak …

Pronunciation learning for automatic speech recognition
… heel of modern automatic speech recognizers (ASRs). Unlike stochastic acoustic and language models that learn the values of their parameters from training data, the baseform pronunciations of words in an ASR vocabulary are typically specified manually, and do not change, unless they are edited …
