Multi revolution finite element model to predict machining induced residual stresses in Inconel 718
(Elsevier, 2013)Inconel 718 is commonly used in structural critical components of aircraft engines due to its mechanical thermal properties at high temperatures, which makes it to be considered as a difficult to machine material. In these ... -
Simulation of distortion due to machining of thin-walled components
(Elsevier, 2013)The distortion of components is strongly related to the residual stress state induced by manufacturing processes like heat treatment, forming or machining. Each process step affects the initial stress state of the following ... -
Evolution of residual stresses induced by machining in a Nickel based alloy under static loading at room temperature
(Elsevier, 2014)Tensile residual stresses are very often generated on the surface when machining nickel alloys. In order to determine their influence on the final mechanical behaviour of the component residual stress stability should be ... -
Numerical Simulation of Surface Modification During Machining of Nickel-based Superalloy
(Elsevier, 2015)The main objective of this study is to implement a reliable FE model of the orthogonal machining of a Nickel based superalloy for the prediction of microstructural changes occurring during the process. A FE numerical model ... -

SDRS: A new lossless dimensionality reduction for text corpora
(Elsevier Ltd., 2020)In recent years, most content-based spam filters have been implemented using Machine Learning (ML) approaches by means of token-based representations of textual contents. After introducing multiple performance enhancements, ... -
Membrane-containing virus particles exhibits mechanics of a composite material for genome protection
(Royal Society of Chemistry, 2018)The protection of the viral genome during extracellular transport is an absolute requirement for virus survival and replication. In addition to the almost universal proteinaceous capsids, certain viruses add a membrane ... -
Factor graph based detection approach for high-mobility OFDM systems with large FFT modes
(Springer, 2012)In this article, a novel detector design is proposed for orthogonal frequency division multiplexing (OFDM) systems over frequency selective and time varying channels. Namely, we focus on systems with large OFDM symbol ... -
Electric Technology in Wind Turbines from a Dialectic Perspective
(Philosophy Documentation Center, 2019)Wind turbines have been used by many groups of humans for many centu-ries. Wind turbines have allowed groups of humans to perform many different tasks in the past (grinding grain, pumping water, etc.). However, ... -
Neural Network Direct Control with Online Learning for Shape Memory Alloy Manipulators
(MDPI AG, 2019)New actuators and materials are constantly incorporated into industrial processes, and additional challenges are posed by their complex behavior. Nonlinear hysteresis is commonly found in shape memory alloys, and the ... -
