Flight energetics in sphinx moths: heat production and heat loss in Hyles lineata during free flight.
1. Mean thoracic temperature of free-flying H. lineata in the field and in the laboratory increased from about 40 degrees C at Ta=16 degrees C to 42-5 degrees C at Ta=32 degrees C. At a given Ta, thoracic temperature was independent of body weight and weakly correlated with wing loading. 2. The difference between abdominal temperature and air temperature increased from 2 degrees C at low Ta to ...
متن کاملFlight energetics of sphinx moths: power input during hovering flight.
The energetic cost of hovering flight was measured in sphinx moths from five species. Mean power input per unit mass (Pi/M) varied from 237-2 W kg-1 in Manduca sexta (Subfamily:Sphinginae), mean body mass 1-2 X 10(-3) kg, to 327-9 W kg-1 in Deilephila elpenor (Subfamily: Macroglossinae) mean body mass 7-3 X 10(-4) kg. Mean Pi/M for the five species was inversely proportional to mean body mass a...
متن کاملSphinx Parallelization
Speech recognition applications challenge traditional out-of-order processors because of low cache locality and poor branch behavior. We observe that these symptoms may be mitigated my exploiting the existing parallelism in these algorithms. In this project, we exploit many levels of parallelism in Sphinx, a leading speech recognition system, to improve architectural utilization by decreasing c...
متن کاملIncorporating Lr Parsing into Sphinx
This paper describes the integration of an LR natural language parser with the SPHINX speech recognition system. SPHINX is one of the most successful speech recognition systems in use today. Although it attains high word accuracy, SPHINX often outputs ungrammatical recognition results because the baseline SPHINX system uses very simple word-pair or bigram language models. For applications of sp...
متن کاملSphinx: Schema-conscious Xml Indexing
User queries on XML documents are typically expressed as regular path expressions. A variety of indexing techniques for efficiently retrieving the results to such queries have been proposed in the recent literature. While these techniques are applicable to documents that are completely schema-less, in practice XML documents often adhere to a schema, such as a DTD. In this paper, we propose Sphi...
