1. Desidratação osmotica e secagem convectiva de maçã : transferencia de massa e alterações de estrutura celular / Osmotic dehydrations and convective drying apple; : mass transfer and cellular structure changes
In this study it was investigated the osmotic dehydration of apples (Fuji variety) followed or not by convective drying with hot air. Concentration profiles were determined for water and solute(s) in samples of apples cut in half and osmotically dehydrated in binary aqueous solutions (30% and 50% sucrose, w/w) and ternary solution (50% sucrose and 10% sodium

2. Avaliação do uso de observáveis coletadas com receptores de navegação pessoal para determinação de coordenadas em linhas base curtas / Evaluation of the use of observable collected with receivers, personal navigation coordinates to determine base lines short
In recent decades the use of equipment for positioning, particularly the personal navigation receivers gained relative importance, and the acquisition of these receivers has increased considerably. These eceivers, however, were not developed for task that requiring accuracy, because it estimate and store positions with precision and accuracy of the order of

3. NUMERICAL STUDY OF THE INTERACTION BETWEEN A SUPERSONIC JET AND PLANAR SURFACE / ESTUDO NUMÉRICO DA INTERAÇÃO ENTRE UM JATO SUPERSÔNICO E UMA SUPERFÍCIE PLANA
I in this work a study of the interaction between a supersonic jet and a planar surface is presented, with the aim to analyze the behavior of the velocity, pressure and temperature flowfield. This study finds its motivation in the process of thermal spallation of hard rocks, which may result from the interaction between a high pressure and high temperature j

4. AvaliaÃÃo de procedimentos para investigaÃÃo da confiabilidade das cartas cadastrais
Considering the need for evaluating geometric quality of cartographic documents, for engineering projects development as much as for areas, distances and volumes evaluation, and before the absence of a test methodology for such documents, this work presents a methodology for investigating the geometry reliability of cadastral maps. The methodology consists i

5. Uma arquitetura baseada em SCTP e SIP para suporte a aplicações VoIP móveis e a especificação formal do seu módulo de controle
New versions of SCTP protocol allow the implementation of handover procedures in the transport layer, as well as the supply of a partially reliable communication service. A communication architecture is proposed herein, integrating SCTP with the session initiation protocol, SIP, besides additional protocols. This architecture is intended to handle voice appl

6. Sistema de visão robótica para identificação e localização de objetos sob manipulação por robôs industriais em células de manufatura.
There are several techniques for applying robotic vision for identification and localization of industrial objects. These objects are typically found in manufacturing cells. The purpose is to catch and transport the pieces for automatically grouping. Robotic vision for industrial objects is an important and still difficult task, especially feature extraction

7. Study of gas and gas-solid flow in ciclones using computational fluid dynamics technics / "Estudo dos escoamentos gasoso e gas-solido em ciclones pela aplicação de tecnicas de fluidodinamica computacional"
This work is the result of the efforts of the CFD research group of the Chemical Processes Modeling and Simulation Laboratory located at FEQ-UNICAMP to study gas and gas-particle flow in a cyclone. The starting point was to consolidate previous information in cyclone flow using current CFD techniques. Two research lines were applied: the first one has studie

8. DeterminaÃÃo e remoÃÃo de erros em mapas de colheita de milho
The automation of the the monitorated harvest ends introducing systematic errors to the process, for this reason, a methodology of filtering of data became necessary for obtaining confident maps and it treats about the mean error factor, which is the delay time. The delay time is that spent between the cutting of the plant by the platformâs bar and the pass

9. Non-twist field line mappings for tokamaks with reversed magnetic shear
The structure of magnetic field lines in a tokamak with reversed magnetic shear is investigated by means of analytically derived area-preserving non-twist Poincaré maps. The basic configuration is the magnetic field produced by an ergodic limiter, superimposed to the tokamak equilibrium field in suitable coordinates. We consider the cases of one and two res

10. Mass transport in spheroids using the Galerkin method
This work presents an analytical modelling of mass transfer in spheroidal solids using a liquid diffusion model. The diffusion equation, written in cylindrical coordinates, is solved using the Galerkin method with a constant diffusion coefficient and an equilibrium boundary condition at the surface of the solid. Results on the drying kinetics, and moisture c

12. Metodo dos volumes finitos aplicado a modelagem matematica e simulação computacional de um forno aquecido por jato de chama com escoamento em vortice
This thesis had the purpose of reaching a complementary k.nowledge of the intricate inter-relations between the complex phenomena of mass, momentum and energy transfers, which develop in furnaces with vortex flows, by mathematical modelling and computational simulation, in two and three-dimensional approaches. Furthermore, the effects of the bumer design and
