A process for catalytic multi-stage hydrogenation of heavy carbonaceous feedstocks using catalytic ebullated bed reactors is operated at selected flow and operating conditions so as to provide improved reactor operations and produce increased yield of lower boiling hydrocarbon liquid and gas products. The disclosed process advantageously takes advantage of an external gas / liquid separation unit associated with the first stage reactor to allow for a more efficient and effective catalytic hydrocracking process. The more efficient process is primarily a result of the increased catalyst loading and lower gas hold-up in the ebullated reactors.

Methods, systems, and apparatus, including computer program products, for identifying candidate synonyms of transliterated terms for query expansion. In one aspect, a method includes identifying multiple transliterated terms in a target language. For each transliterated term of the multiple transliterated terms in the target language, the transliterated term is mapped to one or more terms in a source language. For a first transliterated term of the multiple transliterated terms in the target language, one or more second transliterated terms of the multiple transliterated terms in the target language are identified as candidate synonyms of the first transliterated term, where each of the one or more second transliterated terms is mapped to at least one term in the source language that is also mapped from the first transliterated term.

The present invention provides a process for separating a good quality information signal from a noisy acoustic environment. The separation process uses a set of a least two spaced-apart transducers to capture noise and information components. The transducer signals, which have both a noise and information component, are received into a separation process. The separation process generates one channel that is substantially only noise, and another channel that is a combination of noise and information. An identification process is used to identify which channel has the information component. The noise signal is then used to set process characteristics that are applied to the combination signal to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify information signal. The information signal may be, for example, a speech signal, a seismic signal, a sonar signal, or other acoustic signal.
