Buckling behaviour of thin-walled cold formed steel platforms subjected to bending
(2008)The paper studies the behaviour of thin walled cold formed steel beams in bending, through nonlinear finite element analysis. These types of beams are usually used as platforms in scaffold configurations. The research aims ... -
Case Series: Bilateral Homonymous Visual Field Defects Due to Bilateral Ischemic Strokes
(2018)SIGNIFICANCE Bilateral strokes are rare and should be considered when patients present with bilateral visual field loss characterized by patterns consistent with right and left-sided homonymous visual field defects. ... -
A combined numerical/experimental prediction method for urban railway vibration
(2017)Railway-induced ground vibrations can cause negative effects to people/structures located in urban areas. One of the main sources of these vibrations is from the large vehicle forces generated when train wheels impact local ... -
Defects, dopants and lithium incorporation in LiPON electrolyte
(2022)Lithium phosphorus oxy-nitride (LiPON) is a candidate solid electrolyte material for potential use in rechargeable lithium-ion batteries. The use of density functional theory simulations has allowed us to gain atomic-scale ... -
The effect of railway local irregularities on ground vibration
(2015)The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on ... -
Enhanced Ultrasonic-Assisted Heterogeneous Fenton Degradation of Organic Pollutants over a New Copper Magnetite (Cu-Fe3O4/Cu/C) Nanohybrid Catalyst
(2020)A copper magnetite nanohybrid catalyst (Cu-Fe3O4/Cu/C), abundant of Schottky interfaces and structural defects, with ultrathin encapsulation of graphitic carbon, was synthesized and tested. The catalyst shows enhanced ... -
Nitrogen-vacancy defects in germanium
(2022)While nitrogen doping has been investigated extensively in silicon, there is only limited information on its interaction with vacancies in germanium, despite most point defect processes in germanium being vacancy controlled. ... -
A Placement-Aware Soft Error Rate Estimation of Combinational Circuits for Multiple Transient Faults in CMOS Technology
(2019)A considerable disadvantage that comes with the downscaling of the CMOS technology is the ever-increasing susceptibility of Integrated Circuits (ICs) to soft errors. Therefore, the study of the radiation-induced transient ... -
Radiation Hardening Legalisation Satisfying TMR Spacing Constraints with Respect to HPWL
(2020)Reduction in device feature sizes and supply voltage renders modern Integrated Circuits (ICs) more susceptible to Soft Errors (SEs), i.e. Transient Faults caused by ionising radiation. Moreover, the RADiation HARDening ... -
Railway ground vibrations induced by wheel and rail singular defects
(2015)Railway local irregularities are a growing source of ground-borne vibration and can cause negative environmental impacts, particularly in urban areas. Therefore, this paper analyses the effect of railway track singular ... -
Short Survey of Artificial Intelligent Technologies for Defect Detection in Manufacturing
(2021)Zero Defect Manufacturing (ZDM) can be described as the set of methodologies and strategies for the elimination of defective components during production, and is one of the main goals of Industry 4.0. ZDM is very appealing ... -
Theoretical investigation of nitrogen-vacancy defects in silicon
(2022)Nitrogen-vacancy defects are important for the material properties of silicon and for the performance of silicon-based devices. Here, we employ spin polarized density functional theory to calculate the minimum energy ... -
Wafer Map Defect Pattern Recognition using Imbalanced Datasets
(2022)The accurate and automatic inspection of wafer maps is vital for semiconductor engineers to identify defect causes and to optimize the wafer fabrication process. This research work seeks to address the pattern recognition ...
