1. Technical recommendations for artificial insemination in sheep
Abstract Artificial insemination (AI) was the first important biotechnology applied to improve the genetics of farm animals. It allows the rapid and massive diffusion of desirable characteristics of males with high productive potential. We describe the different types of estrus induction and synchronization techniques and the use of the AI with fresh, chille

2. Comparison of the influence of stimuli color on Steady-State Visual Evoked Potentials
IntroductionThe main idea of a traditional Steady State Visually Evoked Potentials (SSVEP)-BCI is the activation of commands through gaze control. For this purpose, the retina of the eye is excited by a stimulus at a certain frequency. Several studies have shown effects related to different kind of stimuli, frequencies, window lengths, techniques of feature

3. Desenvolvimento de ferramenta de comparação de técnicas de processamento de sinais para determinar fadiga muscular por meio do sinal emg / Toolkit development for signals processing technics comparison to detect muscular fadigue by EMG signal
This study aimed to development of a computational tool for electromyographic signal (EMG) analysis by signal processing techniques to determine muscular fatigue. With Ethics Committee of Federal University of Goiás approve were recorded from the dominant biceps brachii of 10 volunteers, that did not ever had muscular disease. The protocol consisted on get

4. Técnicas de processamento não linear de sinais aplicadas à investigação de limitações práticas do procedimento de ventilação mecânica não invasiva
Individuals with respiratory system dysfunctions or who are recovering from complex surgeries may have difficulty to sustain spontaneous breathing. The mechanical ventilation is a clinical procedure that supports ventilation until the patient is recovered. Noninvasive mechanical ventilation is especially remarkable as it can be used outside the hospital, in

5. Synchronization in intermittent turbulence and spatiotemporal chaos in the solar-terrestrial environment / Sincronização em turbulência intermitente e caos espaço-temporal no ambiente solar-terrestre
In this work we analyze synchronization due to multiscale interactions in observations of intermittent turbulence and numerical simulations of spatiotemporal intermittency in neutral fluids and space plasmas. This study is carried out in two parts. First, we apply two distinct nonlinear techniques, kurtosis and phase coherence index, to measure the degree of

7. Redes de redistribuição de sinais a partir de redes de freqüência única (SFN)
This dissertation presents details of a structure needed to create a Single Frequency Network (SFN) using low-power transmitters, and a comparison with a network composed of a single transmitter with high power. Among the difficulties to implement networks which distribute signals in SFN, has prioritized the synchronization issue and equalization techniques

8. Workflow modelling using a temporal object-oriented model with roles
The representation of all the processes that compose a workflow, including all the constituent activities, their execution sequence and relationships, the agents responsible for their execution, and the resources that are used during execution, is known as Workflow Modelling. Several techniques are being proposed to model workflow. In this paper a workflow m

9. Projeto e implementação da distribuição de um simulador multinível / Design and implementation of the distribution of a multi-level simulator
O uso de ferramentas de simulação para validar projetos de sistemas digitais é uma prática comum, devido às vantagens que estas trazem ao desenvolvimento destes sistemas, tais como: custo, segurança, velocidade e acuracidade. Porém, a simulação seqüencial de alguns sistemas pode levar várias horas ou até mesmo dias, fazendo desta maneira surgir a

10. Teste de programas concorrentes com memória compartilhada / Test of shared memory concurrent programs
This work presents a novel test model for shared memory concurrent programs. Some important new features in this model are: (1) analysis the communication and synchronization in an isolated manner, (2) examines the synchronization due the start and the finish of threads, and (3) employs a method based on timestamps to check the communication exercised for an

11. ANALISE DA DINAMICA DE PARTICULAS BROWNIANAS INTERAGENTES A PARTIR DE REDES DE MAPAS ACOPLADOS
The Brownian motion is one important topic of the non-equilibrium statistical mechanics and it is related to many natural phenomena. The first observations and theories on this motion were essential for understand the microscopic behavior of the nature and its influence on macroscopics observables. In this dissertation, we studied the dynamics of a system co

12. Avaliação de políticas de escalonamento para execução de simulações distribuídas / Evaluation of politics of scheduling for execution of distributed simulations
A bestter scheduling in distributed simulation is fundamental to a fast and efficient execution. The developed project has as objective the evaluation of performance of conventional and specific politics of scheduling for Distributed Simulation (DS), presenting a comparison of the performance of these two boardings. Analyses of the research done in the area
