Controlling the trajectory of a flexible ultrathin endoscope for fully automated bladder surveillance
(
IEEE
, 2014 , Article)
During cystoscopy, the urologist manually steers a cyst scope inside a patient's bladder to visually inspect the inner surface. Cystoscopies are performed as part of surveillance for bladder cancer, making it the most ...
The probabilistic nature of ignition of turbulent highly-strained lean premixed methane-air flames for low-emission engines
(
Elsevier Ltd
, 2014 , Article)
The probabilistic nature of ignition of turbulent highly-strained lean premixed flames has been investigated. Two flow configurations have been considered in this study; counter-flow and bluff-body flames. Different ...
A validated design methodology for a closed-loop subsonic wind tunnel
(
Elsevier Ltd
, 2014 , Article)
A systematic investigation into the design and simulation of flow parameters in a closed-loop wind tunnel was carried out using Computational Fluid Dynamics (CFD). The analytical model for estimating pressure losses were ...
Synthesis and characterization of electrically conducting copolymers of poly(aniline-co-o-iodoaniline)
(
World Scientific Publishing Co.
, 2014 , Article)
Functionalized copolymers of poly(aniline-co-o-iodoaniline) have been synthesized by the chemical oxidative polymerization method by using o-iodoaniline (o-IA) and aniline (AN) as monomer units by changing their molar feed ...
Effect of microstructural evolution on wettability and tribological behavior of TiO2 nanotubular arrays coated on Ti–6Al–4V
(
Elsevier Ltd.
, 2015 , Article)
Self-organized TiO2 nanotubular arrays were fabricated by electrochemical anodization of Ti–6Al–4V plates in an NH4F/H3PO4 electrolyte. The effect of microstructural evolutions on the wettability and tribological behavior ...
Burden of diabetes mellitus attributable to demographic levels in Qatar: An emerging public health problem
(
Elsevier Ltd
, 2014 , Article)
Diabetes is one of the main contributors to ill health and premature mortality worldwide and its prevalence has been rising during the last decades. Aim The aim of the present study was to quantify the burden of disease ...
Design and numerical study of the integration of omnidirectional shroud with vertical axis wind turbine
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
The integration of a vertical axis wind turbine (VAWT) with the novel omni-directional shroud is proposed. It consists of the upper wall, lower wall and an array of 5 guide-vanes. Wind from all directions is collected ...
Wear resistance investigation of titanium nitride-based coatings
(
Elsevier Ltd.
, 2015 , Article)
The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ...
Comfort-based fuzzy control optimization for energy conservation in HVAC systems
(
Elsevier Ltd
, 2014 , Article)
The work presented herein illustrates the use of computational intelligence and optimization approaches for improving the fuzzy controller's performance in architectural heating, ventilation, and air conditioning system ...
The impact of metal inert gas welding on the corrosion and mechanical behavior of AA 6061 T6
(
Electrochemical Science Group
, 2014 , Article)
An attempt has been made to investigate the effects of MIG welding on the corrosion and mechanical properties of AA 6061 T6. A series of experimental techniques has been conducted to evaluate the corrosion and mechanical ...
