1. MGF Methods for Fixed and Gain Saturated Optically Preamplified FSO Links Impaired by Misalignments and Atmospheric Turbulence
Abstract The Gaussian approximation is commonly used to evaluate the performance of free space optical communication systems. However, other performance evaluation methods such as the saddle point approximation, Chernoff bound and the modified Chernoff bound have also been used. This paper investigates the performance of fixed and gain saturated optically pr

2. ACELERAÇÕES NA INTERFACE CAVALO-CAVALEIRO: REPERCUSSÕES PARA A HIPOTERAPIA
RESUMO A Hipoterapia tem demonstrado resultados positivos na intervenção de disfunções motoras e neurológicas. Estudos que investigam a eficácia desse método descrevem estratégias como variação das superfícies de deslocamento do cavalo, diferentes posições de montaria e a diversificação de equipamentos de montaria para controlar os impulsos tr

3. Thermographic assessment of saddles used in Mangalarga Marchador horses
RESUMO O ajuste inadequado da sela é um dos principais causadores de lombalgias em equinos. A raça Mangalarga Marchador está entre as mais populares do Brasil, sendo muito utilizada para cavalgadas e prática de esportes. O presente estudo teve como objetivo avaliar termograficamente as selas utilizadas em cavalos dessa raça. Para tal, foram realizadas i

4. Biometric parameters of adult and growing Pêga donkeys
ABSTRACT This study aimed at establishing the morphological characteristics and morphometric indexes of Pêga donkeys, utilizing 47 animals, of which 22 were adults and 25 were growing donkeys. Prior to taking their measurements, the animals were restrained and made to stand squarely. The morphological data were measured, and the following morphometric index

5. Energy harvesting through pendulum motion and DC generators
Abstract In this paper a mathematical model was found, and numerical results obtained for the pendulum behavior when coupled to a DC generator. A simple pendulum is vertically excited on its support and consequently exhibiting oscillations and rotations. The motion of the pendulum spins the axis of a DC generator and inducing a current. The dynamic model inv

6. Evaluación de caminos de difusión de Al en UAl4
ABSTRACT Once the stable structure of point defects and concentrations of defects in thermal equilibrium were obtained for each composition of Al of the compound UAl4, we identified, in this work, the more likely mechanisms for Al mobility in UAl4, and we analyzed transition states in the diffusion of Al in UAl4 by the Nudged Elastic Band (NEB) method implem

7. Parameters of the center of pressure displacement on the saddle during hippotherapy on different surfaces
Background: Hippotherapy uses horseback riding movements for therapeutic purposes. In addition to the horse's movement, the choice of equipment and types of floor are also useful in the intervention. The quantification of dynamic parameters that define the interaction of the surface of contact between horse and rider provides insight into how the type of fl

8. The effect of different doses of chloroprocaine on saddle anesthesia in perianal surgery
PURPOSE: To investigate a saddle anesthesia with different doses of chloroprocaine in perianal surgery. METHODS: Total 60 Patients aged 18-75 years (Anesthesiologists grade I or II) scheduled to receive perianal surgery. Patients using saddle anesthesia were randomized to group A, group B and group C with the same concentration (0.5%) chloroprocaine wi

9. Collection of reference of silicophytoliths the flora of the Southwest ParanÃ: subsidies for studies paleoenvironmental / ColeÃÃo de referÃncia de silicofitÃlitos da flora do Sudoeste do ParanÃ: subsÃdios para estudos paleoambientais
Phytoliths bodies are of amorphous silica (SiO2.nH20) produced during the vegetative cycle and plant death after the production can be incorporated into the soil/sediment, and may remain there for extended periods of time. For an analysis consistent fitolÃtica is necessary to compare the sets of phytoliths found in soil and the collections of references phy

10. Periodontal ligament influence on the stress distribution in a removable partial denture supported by implant: a finite element analysis
OBJECTIVES: The non-homogenous aspect of periodontal ligament (PDL) has been examined using finite element analysis (FEA) to better simulate PDL behavior. The aim of this study was to assess, by 2-D FEA, the influence of non-homogenous PDL on the stress distribution when the free-end saddle removable partial denture (RPD) is partially supported by an osseoin

11. An alternating LHSS preconditioner for saddle point problems
In this paper, we present a new alternating local Hermitian and skew-Hermitian splitting preconditioner for solving saddle point problems. The spectral property of the preconditioned matrices is studies in detail. Theoretical results show all eigenvalues of the preconditioned matrices will generate two tight clusters, one is near (0, 0) and the other is near

12. Stability boundary characterization of nonlinear autonomous dynamical systems in the presence of saddle-node equilibrium points
Uma caracterização dinâmica da fronteira da região de estabilidade para uma ampla classe de sistemas dinâmicos autônomos é desenvolvida neste artigo. Essa caracterização generaliza os resultados existentes na medida em que permite a existência de pontos de equilíbrio sela-nó na fronteira da região de estabilidade. Mostra-se que a fronteira da re
