A new species of Lycengraulis Günther, 1868 (Clupeiformes: Engraulinae) from the Amazon basin, Brazil, with comments on Lycengraulis batesii (Günther, 1868).
A new species of Lycengraulis from the Amazon basin is described. Lycengraulis figueiredoi can be distinguished from L. grossidens by a short upper maxilla, its posterior margin not reaching the lower maxilla joint (vs. upper maxilla longer, its posterior margin reaching to or a little past of mandible joint). Lycengraulis figueiredoi can be distinguished also from L. poeyi by 26 to 31 anal-fin...

In this work we present a flexible and fast, but yet accurate simulation environment for wireless systems, which satisfies real-time constraints imposed by the respective applications and protocols of interest. We take into account system and demonstration aspects and concentrate on real-time video-conferencing services. The presented wireless network simulation and demonstration environment (W...
متن کاملMorphological variation and taxonomy of Atractus latifrons (Günther, 1868) (Serpentes: Dipsadidae).
As currently understood Atractus latifrons is widely distributed in South America, occurring from Suriname to the east of the Andes in Bolivia. Throughout this widespread distribution, at least three distinct color patterns were previously reported in the literature. Here, we test whether quantitative variation and qualitative distribution of morphological characters are correlated with any col...
متن کاملStructural analysis of the embryonic development in Brycon cephalus (Günther, 1869).
The embryogenesis of Brycon cephalus was established in seven stages: zygote, cleavage, blastula, gastrula, segmentation, larval and hatching, in an incubation period of 11 h (26 degrees C). The zygote phase was observed directly after fertilization and egg hydration. Cleavage began at 0.5 h of incubation and extended up to the morula phase (1.5 h; +100 blastomeres). Cleavage was meroblastic an...

Using associative memories and sparse distributed representations we have developed a system that can learn to associate words with objects, properties like colors, and actions. This system is used in a robotics context to enable a robot to respond to spoken commands like ”bot show plum” or ”bot put apple to yellow cup”. The scenario for this is a robot close to one or two tables on which there...
