2. Edaphic and Topographic Factors and their Relationship with Dendrometric Variation of Pinus Taeda L. in a High Altitude Subtropical Climate
ABSTRACT The study of the relationships between the yield potential of forest stands and the conditions offered for plant development is fundamental for the adequate management of the forest when aiming at sustainable high yields. However, these relations are not clear, especially in commercial forests, on rugged terrain where relationships between the lands

3. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

4. Stochastic modeling of flexible rotors
Flexible rotors are characterized by inherent uncertainties affecting the parameters that influence the dynamic responses of the system. In this context, the handling of variability in rotor dynamics is a natural and necessary extension of the modeling capability of the existing techniques of deterministic analysis. Among the various methods used to model un

5. MODELING OF WATER, SEDIMENT AND PHOSPHORUS LOADS IN AN AGRICULTURAL WATERSHED IN SOUTHERN BRAZIL / MODELAGEM DO ESCOAMENTO, DA PRODUÇÃO DE SEDIMENTOS E DA TRANSFERÊNCIA DE FÓSFORO EM BACIA RURAL NO SUL DO BRASIL
Areas under intensive tobacco crop cultivation have been impacting the water balance and increasing soil erosion in Southern Brazil. Application of large amounts of mineral fertilizers, higher than the tobacco requirement, contributes to excessive phosphorus loads in soil and water bodies. The assessment of potential environmental impacts due to changes in l

6. A tutorial on hypercube queueing models and some practical applications in Emergency Service Systems
This paper presents some extensions and applications of hypercube queueing models todescribe server-to-customer type Emergency Service Systems. The classical hypercube is a well-known spatially distributed queueing model effective in analyzing these systems, based on Markovian analysis approximations. Experience has shown that each real life Emergency Servic

7. Análise da configuração de SAMU utilizando modelo hipercubo com prioridade na fila e múltiplas alternativas de localização de ambulâncias
In some emergency medical systems the service demand is high due to the treatment of patients in the range severe to mild, which increases the utilization level of the servers. In these systems, may be queues formation and so the need to explicitly consider priority in care is extremely important. In this study we extend the hypercube model to deal with this

8. Análise,Simulações e Aplicações Algorítmicas de Caminhadas Quânticas / Analysis,Simulations and Algorithmic Applications of Quantum Walks
Quantum computing is a model of computation based on the laws of quantum mechanics, which can be used to develop faster algorithms. The development of efficient quantum algorithms, however, is a highly challenging task. A recent successful approach is the use of quantum walks. In this work, we have studied the quantum walk on the hypercube, obtaining the exa

9. DEFINIÇÃO DA ÁRVORE DE CENÁRIOS DE AFLUÊNCIAS PARA O PLANEJAMENTO DA OPERAÇÃO ENERGÉTICA DE MÉDIO PRAZO / DEFINITION OF THE STREAMFLOW SCENARIO TREE TO LONG-TERM OPERATION PLANNING
In the planning operation the currently used model in the long-term operation planning of the Brazilian Interconnected System, the uncertainty concerning streamflow is considered explicitly in the estimation of the expected cost-to-go function, as well as in the covering of the state space, by the use of multivariate hydrological scenarios. The set of all po

10. Um estudo de métodos de solução do modelo hipercubo de filas para sistemas de grande porte / A study of hypercube queueing model solution methods for large scale systems
The planning of public and private service systems is essential to assure the quality of the services realized by these systems. A model that has been widely used for planning server-to-customer service systems is the Hypercube Queueing model. The Hypercube Queueing model is an analytical stochastic model that allows the evaluation of different configuration

11. UM SISTEMA DE GERAÇÃO DE EXPRESSÕES FACIAIS DINÂMICAS EM ANIMAÇÕES FACIAIS 3D COM PROCESSAMENTO DE FALA / A SYSTEM FOR GENERATING DYNAMIC FACIAL EXPRESSIONS IN 3D FACIAL ANIMATION WITH SPEECH PROCESSING
Esta tese apresenta um sistema para geração de expressões faciais dinâmicas sincronizadas com a fala em uma face realista tridimensional. Entende-se por expressões faciais dinâmicas aquelas que variam ao longo do tempo e que semanticamente estão relacionadas às emoções, à fala e a fenômenos afetivos que podem modificar o comportamento de uma face

12. Otimização da configuração e operação de sistemas médicos emergenciais em rodovias utilizando o modelo hipercubo.
The purpose of this study is to develop effective methods to analyze the configuration and operation of the emergency medical systems (EMS) on highways. Due to the stochastic nature of these systems, especially in the arrival and assistance processes of the emergency calls, we apply the Hypercube Queuing Model to evaluate the performance measures of the syst
