Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)
Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ...
Designing of a powder compressing device with vibration and investigation of compressibility of MgO powders with this device
(Elsevier Sci Ltd, 2007)
One of metal matrix composite (MMC) production methods is infiltration of liquid metal into preformed reinforcement. In this method, MMCs are produced by infiltration of liquid metal into preformed reinforcement using one ...
Determination of residual stresses based on heat treatment conditions and densities on a hybrid (FLN2-4405) powder metallurgy steel using artificial neural network
(Elsevier Sci Ltd, 2007)
This paper presents a new approach based on artificial neural networks (ANNs) to determine the residual stresses in PM steel based nickel (FLN2-4405). This study consists of two cases: (i) The experimental analysis: The ...
Modelling of yield length in the mould of commercial plastics using artificial neural networks
(Elsevier Sci Ltd, 2007)
According to the yield length of a plastic, whether a mould is filled fully or not can be estimated. In this study, a new formula based on various injection parameters was developed to determine the yield length in plastic ...
Effect of chronic diseases and associated psychological distress on health-related quality of life
(Wiley, 2007)
Background: The purpose of this study was to clarify the correlations between the presence of comorbidities and psychological distress and health-related quality of life (HRQL). This was a population-based cross-sectional ...
Reconstruction of mandibular defects using autografts combined with demineralized bone matrix and cancellous allograft
(Lippincott Williams & Wilkins, 2007)
Facial bone defects can be managed by a variety of means, such as inlay or onlay applied nonvascularized bone grafts, local pedicled/distal free osteocutaneous/osseous flaps or distraction osteogenesis. Although each method ...
