Recent work on natural language processing systems is aimed at more conversational, context-adaptive systems in multiple domains. An important requirement for such a system is the automatic detection of the domain and a domain consistency check of the given speech recognition hypotheses. We report a pilot study addressing these tasks, the underlying data collection and investigate the feasibili...

In this paper, we investigate the system performance of a multi-cell multi-user (MU) hybrid millimeter wave (mmWave) multiple-input multiple-output (MIMO) network adopting the channel estimation algorithm proposed in [1] for channel estimation. Due to the reuse of orthogonal pilot symbols among different cells, the channel estimation is expected to be affected by pilot contamination, which is c...

An automatic repeat request (ARQ) scheme using rate compatible trellis coded modulation, pilot symbol aided channel estimation, soft output packet combining, and a retransmission request strategy supporting a variable quality of service within a packet is proposed. Simulation results show that this type II hybrid ARQ has about 3–5 dB SNR gain over its type I ARQ counterpart. Keywords— Hybrid AR...

We present a pilot study for using transformation-based learning for automatic correction of rule-based machine translation. Correction rules are learned based on a parallel corpus of machine translations from a commercial machine translation system and a human-corrected version of these translations. The correction rules exploit information on word forms and part of speech. The experiment resu...

This paper presents the use of different artificial life-based optimization algorithms and cerebellar model articulation controllers (CMACs) in aircraft automatic landing control. The proposed intelligent control system can act as an experienced pilot and guide the aircraft landed safely in wind disturbance condition. Lyapunov theory is applied to obtain adaptive learning rule and stability ana...

We describe an ongoing effort to build a large-scale parallel and comparable monolingual treebank for Dutch of 1 million words, where nodes of dependency trees are aligned and labeled according to a limited set of semantic similarity relations. We address alignment of sentences and dependency trees, both manual and automatic. We introduce new annotation tools, present results from pilot experim...

This paper presents work on using prosody in the output of spoken dialogue systems to resolve possible structural ambiguity of output utterances. An algorithm is proposed to discover ambiguous parses of an utterance and to add prosodic disambiguation events to deliver the intended structure. By conducting a pilot experiment, the automatic prosodic grouping applied to ambiguous sentences shows t...

We describe an ongoing effort to build a large-scale parallel/comparable monolingual treebank for Dutch of 1 million words, where nodes of dependency trees are aligned and labeled according to a limited set of semantic similarity relations. We address alignment of sentences and dependency trees, both manual and automatic. We introduce new annotation tools, present results from pilot experiments...

The Wright brothers followed their invention of the first practical airplane (1903) with a second epochal invention, the angle of attack sensor and aircraft stabilizer (1908). Both inventions were patented and details of each are contained in the respective patents for these two aeronautical advances. This paper emphasizes how the angle of attack sensor actuated an "automatic stabilizer." This ...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the Western Atlantic: the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala sp. and is identified as such. The specie...
