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 ...

(
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 ...
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 ...

(
Trans Tech Publications Ltd
, 2014 , Article)
Aluminium alloy 6061 T6 circular specimens were joined using TIG welding method. AlMg5 was used as filler. The corrosion behavior of welded and un-welded AA 6061 T6 was investigated using potentiodynamic and open circuit ...
Application of Ni and Cu nanoparticles in transient liquid phase (TLP) bonding of Ti-6Al-4V and Mg-AZ31 alloys
(
Springer US
, 2014 , Article)
The transient liquid phase (TLP) bonding of Ti-6Al-4V alloy to a Mg-AZ31 alloy was performed using an electrodeposited Ni coating containing a dispersion of Ni and Cu nanoparticles. Bond formation was attributed to two ...
A continuum model with a percolation threshold and tunneling-assisted interfacial conductivity for carbon nanotube-based nanocomposites
(
American Institute of Physics Inc.
, 2014 , Article)
A continuum model that possesses several desirable features of the electrical conduction process in carbon-nanotube (CNT) based nanocomposites is developed. Three basic elements are included: (i) percolation threshold, ...
