There has been significant interest in recent years in the utility and implementation of autonomous underwater and surface vehicles (AUVs and ASVs) for persistent surveillance of the ocean. Example studies include the dynamics of physical phenomena, e.g., ocean fronts, temperature and salinity profiles, and the onset of harmful algae blooms. For th...

The study of a marine environment is a challenging task because of the spatio–temporal variations of ocean phenomena and the disturbances caused by ocean currents. As such, we must collect data over long time periods to better assess and understand marine environments. To achieve this, we investigate the long-term trajectories of inexpensive and un...

This paper presents a review of Environmental Niche Modeling and a methodology for isolating the environmental niche of an aquatic species, given that prior information is available for characterising the physical tolerances for that species. To test and demonstrate our methodology, the environmental niche of the kelp bass has been isolated within...

Resumo-Sistemas de resfriamento evaporativo envolvem processos de transferência de calor e massa no resfriamento do ar, porém, existe uma incerteza na variável de fração de área molhada da placa. Em vista disso, objetivou-se com esse trabalho, desenvolver um software para análise da fração molhada da placa evaporativa, por meio de modelos matemátic...

The underactuated vehicles are apposite for the long-term deployment and data collection in spatiotemporally varying marine environments. However, these vehicles need to estimate their positions (states) with intrinsic sensing in their long-term trajectories. In previous studies, autonomous underwater vehicles have commonly used vision and range se...

To effectively examine ocean processes, sampling campaigns require persistent autonomous underwater vehicles that are able to spend a majority of their deployment time maneuvering and gathering data underwater. Current navigation techniques rely either on high-powered sensors (e.g. Doppler Velocity Loggers) resulting in decreased deployment time, o...

Com o objetivo de analisar o efeito da idade e a temperatura do ar nas respostas produtivas de frangos de corte, conduziu-se um experimento com animais criados de 1 a 21 dias de idade em túneis de vento climatizados cujos resultados observados foram utilizados no desenvolvimento e teste de um modelo matemático Fuzzy capaz de quantificar esta relaçã...

Na primeira semana de vida, frangos de corte são muito sensíveis a condições diferentes de suas temperaturas de conforto. Dessa forma, objetiva-se com o presente trabalho avaliar o comportamento e as respostas produtivas de frangos de corte submetidos a condições de conforto e estresse térmico em diferentes intensidades (27; 30; 33 e 36ºC) e períod...

The goal of the present work was the instrumentation and validation of a laboratory equipped with a control system for air temperature (t air), relative air humidity (RH) and air velocity (V) to study the environment for small animals. An experimental was equipped with two air conditioners to manage basic t air and RH in order to work. Four wind tu...

O objetivo deste trabalho foi desenvolver, validar e comparar 190 modelos baseados em inteligência artificial, para predizer a massa corporal de pintinhos de 2 a 21 dias de vida, submetidos a diferentes períodos e intensidades de estresse térmico. O experimento foi realizado com 210 pintinhos, em quatro túneis de vento climatizados. Um banco de dad...
