1. Arsenic and Other Elements Determination in Seawater Using Coprecipitation and Standard Mode Inductively Coupled Plasma Mass Spectrometry
The present work aims the determination of As, Co, Cr, Cu, Mn and Pb in seawater samples using coprecipitation extraction procedure before standard mode inductively coupled plasma mass spectrometry (ICP-MS) (no collision/reaction cell). The coprecipitation procedure is based on the precipitation of Mg(OH)2 from the reaction of the Mg2+ ions (present into the

3. Simulation and manufacturing of a miniaturized exponential UWB TEM horn antenna for UWB radar applications
This paper presents the parameterization of the structure of a miniaturized exponential UWB TEM horn antenna and its effect on the matching impedance and directivity. In addition, a microstrip balun that feeds the antenna was proposed in order to improve the balance, and the return loss for low frequencies. Both the antenna and the microstrip balun were simu

5. Algoritmos rápidos de detecção de colisão : broad phase utilizando KD-trees / Algoritmos Rápidos de Detecção de Colisão Broad Phase utilizando KD-Trees.
In this work, three novel and fast broad phase collision detection algorithms, which utilize the spatial partitioning structure known as KD-Tree, were proposed and implemented: KDTreeSpace, DynamicKDTreeSpace and StatelessKDTreeSpace. These algorithms were integrated to the Open Dynamics Engine (ODE) library, which is in charge of calculating the motion of t

6. DETERMINATION OF TOTAL AS IN OCEANIC WATER BY HG AFS / DETERMINAÇÃO DE AS TOTAL EM ÁGUAS OCEÂNICAS POR HG AFS
The increase in industrial activity has increased human exposure to metals and metalloids exponentially. In this context, arsenium is a good example, being increasingly found in several natural environments. It is an element with no essential biological function, and possessed of elevated toxicity. The discharge of toxic elements in aquatic bodies can promot

7. TÉCNICAS DE NAVEGAÇÃO 3D USANDO O CUBO DE DISTÂNCIAS / 3D NAVIGATION TECHNIQUES USING THE CUBE MAP
The use of 3D viewers is becoming common in several activities. The appearance of new technologies, with the resulting increase in processing power, made possible the creation of larger and richer 3D virtual environments. However, the navigation in 3D environments, especially the multiscale ones, is still a problem for many users. The goal of this work is to

9. Árvores BSP semi-ajustáveis / Semi-adjusting BSP tree
A etapa de broad-phase para a detecção de colisão em cenas compostas de n objetos que se movimentam é um problema desafiador, pois enumerar os pares de colisão revela uma complexidade quadrática. Estruturas de dados espaciais são desenvolvidas para acelerar o processo, mas muitas vezes a natureza estática dessas estruturas dificulta o manejo de cenas

11. Structural health monitoring of composite materials subjected to impacts using the electromechanical impedance technique / Monitoramento de integridade estrutural de materiais compostos sujeitos a impactos empregando a técnica da impedância eletromecânica
Nowadays, composite materials have increasingly replaced traditional materials in applications that require improved performance, safety, economy and durability. Nonetheless, such materials exhibit complex damage mechanisms that cannot be easily detected in early stages. Failures can occur during manufacturing, operation or even in the course of maintenance.

12. GPU-BASED PARTICLE SIMULATION WITH COLLISION HANDLING / SIMULAÇÃO DE PARTÍCULAS BASEADA EM GPU COM TRATAMENTO DE COLISÃO
This work presents a new proposal for the implementation of a GPU-based particle system. The simulation runs entirely on the graphic processor, thus eliminating data transfer between the CPU and the GPU. The proposed system is able to simulate particles with different diameters in confined environments, including support for inter-particle collisions, constr
