Aplicações do modelo presa-predador ao estudo da influência da dinâmica populacional de espécies de sardinha, cavala e atum e sobre o processo de eutrofização marinha

A discussion concerning marine eutrophication, possible generated from an imbalance of fish population is presented. Simulations through a code in FORCE 2.0 considering a predator-prey model have been made and the numerical results for a three different fish species were plot in ORIGIN code. The populations considered in this study were: Sardines being prey and both mackerel and tuna being the sardine’s predators. Some hipotheses concerning to the marine eutrophication have being made according to the stages of the dynamics of the system. For situations were the prey’s populationis very low, the quality of the water experiences a strong depreciation leading to a possible eutrophication of the water.

Filtragem de sinais de interferência em espectros dinâmicos solares através de suas componentes de Fourier

Through the data acquisition system of the instrument Brazilian Solar Spectroscope (BSS) at INPE, solar observations in the decimetric radio wave band (1000-2500 MHz) are regularly made. This data is showed as dynamic spectra using the software BSSView created for this purpose. The process of data acquisition can be influenced by various sources, dificulting the resulting dynamic spectrum analysis. The objective of this work is to create a computational routine that eliminates dynamic components of the spectrum attributed to interfering signals and integrate it into BSSView. It was done a preliminary study on the programming language Interactive Data Language (IDL), in which the BSSView was developed, and the Fourier transform, that is required for the application of the filter

Concepção e implementação de um serviço baseado em localização na plataforma ANDROID/GOOGLE

The mobile application proposed in this undergraduate project, classified as a Location-Based Service and named Traveller, was developed to support users of mobile phones equipped with GPS in unknown locations by providing information about weather, location of users and stores in urban areas. The mobile devices whose this project is intended are those equipped with Android. The programming language Java was selected and the Eclipse development environment was used along with the toolkit for developing Android (ADT - Android Development Tools)

Reconhecimento de voz para aplicações em automação implementado em FPGA

In many movies of scientific fiction, machines were capable of speaking with humans. However mankind is still far away of getting those types of machines, like the famous character C3PO of Star Wars. During the last six decades the automatic speech recognition systems have been the target of many studies. Throughout these years many technics were developed to be used in applications of both software and hardware. There are many types of automatic speech recognition system, among which the one used in this work were the isolated word and independent of the speaker system, using Hidden Markov Models as the recognition system. The goals of this work is to project and synthesize the first two steps of the speech recognition system, the steps are: the speech signal acquisition and the pre-processing of the signal. Both steps were developed in a reprogrammable component named FPGA, using the VHDL hardware description language, owing to the high performance of this component and the flexibility of the language. In this work it is presented all the theory of digital signal processing, as Fast Fourier Transforms and digital filters and also all the theory of speech recognition using Hidden Markov Models and LPC processor. It is also presented all the results obtained for each one of the blocks synthesized e verified in hardware
