The purpose of this article is to describe an outreach program based on the engineering design of a robotic musical instrument aimed to the segment of the population not served by traditional academic initiatives or outreach programs. It aims to contribute to develop the interest among children and youngsters in pursuing scientific and technology careers and also mitigating science illiteracy among...
One of the main goals of Distributed Artificial Intelligence is to devise methods to join a community of Computational Agents into a Multi-Agent System, where these agents can cooperate to reach common goals. Cooperation in a Cognitive Agent community is usually supported by an Agent Communication Language (ACL) which allows the agents to exchange knowledge and information through a computer network...
We have been using scientific echo-sounders to map and quantify Engraulis anchoita in the Southern coast of Brazil. This is a low trophic level species and a link from primary producers to top predators. Echo-records collected along thousands of nautical miles contain information about migratory habits and abundance of this fish. Fishing down the food web is a late 90s concept that called international...
The Fisheries Technology and Hydroacoustics Laboratory (TECPESQ-Institute of Oceanography, University of Rio Grande-IO-FURG-Brazil) has traditionally dedicated its working group to fish stock assessments using hydroacoustics. This technique allows the remote detection of organisms throughout the transmission of acoustic energy and the evaluation of the echoes. In order to attend different projects,...
Two acoustic assessment cruises were carried out (February, 2010 and January,2011) in three, 10 by 10 nautical mile exploratory oil blocks, previously to the start of the drilling operation, within a sardine (Sardinella brasiliensis) fishing area. Biological data were collected with zooplankton and mid water trawl hauls. Hydroacoustics with echo-integration were conducted day and night along the whole...
