1. Investigation of High-Speed Cryogenic Machining Based on Finite Element Approach
Abstract The simulation of cryogenic machining process because of using a three-dimensional model and high process duration time in the finite element method, have been studied rarely. In this study, to overcome this limitation, a 2.5D finite element model using the commercial finite element software ABAQUS has been developed for the cryogenic machining proc

2. Drying kinetics of potato pulp waste
Potato pulp waste (PPW) drying was investigated under different experimental conditions (temperatures from 50 to 70 °C and air flow from 0.06 to 0.092 m³ m- 2 s- 1) as a possible way to recover the waste generated by potato chip industries and to select the best-fit model to the experimental results of PPW drying. As a criterion to evaluate the fitting of

3. Analysis of Total Ionizing Dose Effects on 0.13 µm Technology-Temperature-Compensated Voltage References
ABSTRACT: The purpose of this work is to briefly discuss the effects of the total ionizing dose (TID) on MOS devices in order to estimate the results of future irradiation tests on temperature-compensated voltage references that are implemented on a mixed-signal chip fabricated using IBM 0.13 µm technology. The analysis will mainly focus on the effects of t

5. The use of an axisymmetric formulation of the Finite Volume Method for the thermal analysis of the retina and ocular tissues following implantation of retinal prosthesis
This study analyzes the heat transfer in human eyes following implantation of retinal prostheses using an axisymmetric formulation of the Finite Volume Method. The model used consisted of a vertex centered unstructured grid finite volume method in an edge-based data structure and an explicit time integration. The results of the finite volume thermal analysis

7. Finite element simulations of Ti6Al4V titanium alloy machining to assess material model parameters of the Johnson-Cook constitutive equation
The machining of titanium alloys poses several inherent difficulties owing to their unique mechanical properties and cutting characteristics. Finite element (FE) simulations have reduced the burden of extensive experimental trials in understanding the deformation behavior and optimize the cutting process. The FE code relies on the qualitative nature of input

8. Uma contribuição para o estudo das deformações residuais proporcionadas pelo processo de usinagem por fresamento. / A contribution for residual deformation study originated by the face milling machining process.
The face milling operation purpose is providing flat machined surfaces free from residual strains at the cross section of the workpiece. On the other hand, the evidences presented in this thesis are enough to demonstrate that the strain exists and its behavior can be related to technical measurements such as the cutting tool helical profile, the feed rate, t

9. SELEÇÃO DE CLONES DE BATATA DE CURTA DORMÊNCIA, ALTA QUALIDADE DE PROCESSAMENTO E ADAPTADOS AOS CULTIVOS DE PRIMAVERA E OUTONO / SELECTION OF POTATO CLONES WITH SHORT DORMANCY, HIGH PROCESSING QUALITY AND ADAPTED TO SPRING AND AUTUMN GROWN SEASONS
Selection of potato clones might be done during spring and autumn grown seasons of Rio Grande do Sul (RS). These grown seasons have contrasting conditions of temperature, photoperiod and solar irradiation, which may affect tuber dormancy and chip processing quality. The objectives of this work were to identify potato clones with short dormancy, high chip qua

10. Sistemas para manipulação quantica em estado solido / Towards an implementation of quantum manipulation in solid states
This thesis proposes and implements a system for quantum information processing, focusing primarily on the associated instrumentation. The basic physical aspects for computation, such as the associated energy and Shannon s entropy, were revisited. InAs:GaAs quantum dots were elected as the physical system of choice for this implementation; in particular, the

The purpose of this thesis was to study the machinability of low carbon free-machining leaded steel (ABNT/AISI 12L14) with different levels of residual (tramp) elements such as chromium, nickel and copper. Nine batches of steel were produced with controlled chemical composition, and with alterations in the mentioned residual levels so as to apply two levels

12. Diagnostic of turning pperation of ABNT 304 stainless steel through chip analysis / Diagnóstico do processo de torneamento do aço inoxidável ABNT 304 a partir do estudo da formação do cavaco
Os aços inoxidáveis são materiais que apresentam em geral baixa usinabilidade devido principalmente à alta taxa de encruamento durante a usinagem e produção de cavacos longos que levam a um desgaste acelerado da ferramenta. Por isso, torna-se importante identificar a relação entre a evolução do desgaste e a morfologia do cavaco. Foram realizados te
