Determinação da faixa de conforto térmico para galinhas poedeiras na fase inicial de criação
Tendo em vista a importância da avicultura de postura nacional e a premente necessidade do Brasil em verificar as temperaturas de conforto realmente adequadas às aves aclimatizadas ao país, foi realizado este experimento com o objetivo de avaliar, para pintainhas de postura leves da linhagem …

Características de cama aviária de casca de café submetida a diferentes condições ambientais e a influência no potencial de emissão de amônia e em lesões do coxim plantar de frangos de corte
A produção avícola vem crescendo em grandes proporções no Brasil ao longo dos últimos anos. À medida que essa produção aumenta, maiores quantidades de resíduos são gerados. A cama aviária é o principal resíduo gerado por essa atividade e vem sendo estudada por diversos pesquisadores devido à …

Crowdview: uma plataforma crowdsourcing para gerenciamento temporal de entidades
… grows substantially. In many cases this data is described in unstructured forms such as videos, images and texts. Algorithms for extracting data from unstructured forms are not yet accurate. In this case, it is appropriate to use the crowd to solve these tasks. In this context, crowdsourcing …

Stratigraphic sedimentary inversion using paths in graphs
… of analysing quantities of given sediments deposited in sampled regions of a depositional space and calculating the total volumes that are necessary to match the sampled data in a forward depositional simulation. This is a central problem in geology and oil exploration. Attempts to solve …

Interface natural em 3D para animações interativas
… a movement or action and allows the user to provide animations by moving the control cursor in the 3D space with a 2D mouse. In our system, interaction with the virtual environment takes place through more sophisticated tools capable of capturing gestures and hand movements in real time. The …

DF-DTM :explorando redundância de tarefas em dataflow
… studied in the context of the Dataflow [1–4] model, which has been gaining traction in the high-performance computing community, due to its inherent parallelism. Dataflow programs are represented by directed graphs where nodes are instructions or tasks and edges denote data dependencies between …

Programação contínua: propriedades das soluções
… with the Continuous Programming Problem, regarded as a continuous version of discrete problems in linear programming. First we treat the case in which the constraints are linear, in the space of bounded Lebesgue-measurable functions, presenting results involving extensive use of duality. To …

Um método proximal inexato com distâncias proximais para problemas de equilíbrio Quase-monótono
… distances and the diagonal subdifferential. Under some natural assumptions on the problem and the quasimonotonicity condition on the bifunction, we prove that the sequence generated for the method converges to a solution point of the problem.

Estudo de alguns problemas de transporte em redes com fluxo dinâmico
Dynamic transportation problems are defined as transportation problems in graphs with dynamic flow. The dynamic flow graph model presented in this work represents networks such that each branch admits as incoming flow and an outgoing flow, these flows not being necessarily equal. A differencial …

Um desacoplamento canônico para sistemas lineares multivariáveis
Presented a new method for the decoupling of multivariable, time-invariant, linear systems. The method utilizes the Invariant Factors and the Rational Canonical Form of a matrix. Necessary and sufficient conditions are given for the input-state-output decoupling of the system. System …

Método do ponto proximal com distância de Bregman para problemas de minimização quase convexos
In this work, we study the convergence of the proximal point method for solving a constrained minimization problem within the nonnegative orthant for quasiconvex functions. To this end, the Euclidian distance in the regularization term of the classic proximal point method is replaced by a map with …
