The rheological behavior and surface charging of gelcasting alumina suspensions
(2008)
Aim of this work is to investigate the effect of monomers containing either carboxylate (ammonium acrylate) or acrylamide (hydroxymethylacrylamide) functional groups on the surface charging and rheological behavior of ...
The study of natural radiation distribution in soil of São Bernardo do Campo.
(2008-10-05)
We have studied the distribution of natural radioactivity in the soil of five sites of the city São Bernardo do Campo, São Paulo, Brazil. The main contribution of the radiation dose is due to the isotope 40K, with smaller ...
Effect of rolling on the residual stresses and magnetic properties of a 0.5% Si electrical steel
(2008)
Cold-rolled (0-19% of reduction) 0.5% Si electrical steel sheets were studied in detail, including macro and micro residual stress measurements, crystallographic texture, dc-hysteresis curves and iron losses. Even for the ...
Estudo de transistores SOI MOS de perfil trapezoidal através de simulação numérica tridimensional
(Centro Universitário da FEI, São Bernardo do Campo, 2008)
Os dispositivos SOI MOS de múltiplas portas estão entre os transistores não planares de melhor desempenho, uma vez que, ao possuir o canal envolvido por mais de uma porta é maior o controle sobre as cargas no interior do ...
Advantages of graded-channel SOI nMOSFETs for application as source-follower analog buffer
(2008)
In this work the performance of graded-channel (GC) SOI MOSFETs operating as source-follower buffers is presented. The experimental analysis is performed by comparing the gain and linearity of buffers implemented with GC ...
Inductive learning spatial attention
(2008)
This paper investigates the automatic induction of spatial attention from the visual observation of objects manipulated on a table top. In this work, space is represented in terms of a novel observer-object relative reference ...
Surface integrity analysis in the super duplex stainless steel ASTM-A890 after machining
(2008)
The purpose of this paper was to study the main effects of the turning in the superficial integrity of the duplex stainless steel ASTM A890-6A. The tests were conducted on a turning centre with carbide tools and the main ...
Modelagem analítica de transistores SOI de canal gradual com porta dupla
(Centro Universitário da FEI, São Bernardo do Campo, 2008)
Apresenta-se neste trabalho o desenvolvimento de um modelo analítico para transistores nMOSFET de porta dupla (Double-Gate - DG) com canal gradual (Graded-Channel - GC) fabricados em tecnologia Silício sobre Isolante ...
Análise estatística multivariada de imagens cerebrais de controle e pacientes com transtorno obsessivo compulsivo
(Centro Universitário da FEI, São Bernardo do Campo, 2008)
Preocupações, dúvidas e comportamentos ritualizados são, com certeza, fenômenos necessários para a adaptação dos seres humanos e de diversas outras espécies. No momento em que estes fenômenos passam a ocorrer de maneira ...
