Effect of green machining on distortion and surface finishing in advanced ceramic
(2012-11-28)
An alternative for grinding of sintered ceramic is the machining on the green state of the ceramic, which presents easy cutting without the introduction of harmful defects to its mechanical resistance. However, after ...

In Vitro Evaluation of Surface Roughness and Microhardness of Restorative Materials Submitted to Erosive Challenges
(Operative Dentistry Inc, 2011-07-01)
The aim of this study was to evaluate the effect of different acidic solutions on the microhardness and surface roughness of restorative materials. The 120 specimens of restorative materials (Fuji II LC, Vitremer, Supreme ...
O uso da teoria de conjuntos aproximados na modelagem de bases de dados relacionais e na extração de conhecimento.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2005-05-13)
This work investigates two relational database models that extend the standard relational database model. Both models extend the standard relational model by allowing ways to represent
uncertainty. The rough relational ...
Describing soil surface microrelief by crossover length and fractal dimension
(Brasil, 2007)
Accurate description of soil surface topography is essential because different tillage tools produce different soil surface roughness conditions, which in turn affects many processes across the soil surface boundary. ...

Extrapolation for multilinear Muckenhoupt classes and applications
(Elsevier Science, 2020-10-28)
In this paper we solve a long standing problem about the multivariable Rubio de Francia extrapolation theorem for the multilinear Muckenhoupt classes , which were extensively studied by Lerner et al. and which are the ...
Proposta metodologica para o estudo da integridade superficial do aço SAE 8640 no torneamento com inserto quadrado de metal duro
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2021-08-17)
Material machining is a process widely used in component manufacturing. In the process, the understanding of the variables present determines the final result in terms of speed, resources spent and the final quality of the ...
Wheel wear and workpiece surface analyses after grinding hardened steel with minimum quantity lubrication technique assisted with wheel cleaning jet (MQL-AWCJ)
(2018-01-01)
Minimum Quantity Lubrication (MQL) technique has been consolidated in the machining processes as an alternative to conventional technique because of its cleaner production characteristics. However, for grinding process ...
