Electrospun polyvinyl alcohol membranes incorporated with green synthesized silver nanoparticles for wound dressing applications.
(
Springer Verlag
, 2018 , Article)
Electrospun membranes have the potential to act as an effective barrier for wounds from the external environment to prevent pathogens. In addition, materials with good antibacterial properties can effectively fight off the ...
Fault detection and severity identification of ball bearings by online condition monitoring
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
This paper presents a fast, accurate, and simple systematic approach for online condition monitoring and severity identification of ball bearings. This approach utilizes compact one-dimensional (1-D) convolutional neural ...
Influence of CuO nanoparticles and graphene nanoplatelets on the sensing behaviour of poly(vinyl alcohol) nanocomposites for the detection of ethanol and propanol vapors
(
Springer New York LLC
, 2018 , Article)
Poly(vinyl alcohol)/copper oxide/graphene nanoplatelets (PVA/CuO/Gr-NPls) nanocomposite based chemiresistive alcohol sensors were fabricated using colloidal blending method. The PVA/CuO/Gr-NPls nanocomposite films were ...
Nonlinear stochastic drillstrings vibrations: Parametric study for stick-slip suppression
(
Institute of Physics Publishing
, 2018 , Conference Paper)
Unstable vibrations caused by the transition between static and kinetic frictions produces stick-slip motions which is one of the primary causes of poor drilling efficiency and mechanism failure in the drilling process. ...
Influence of functionally graded pores on bone ingrowth in cementless hip prosthesis: a finite element study using mechano-regulatory algorithm
(
Springer Verlag
, 2018 , Article)
Cementless hip prostheses with porous outer coating are commonly used to repair the proximally damaged femurs. It has been demonstrated that stability of prosthesis is also highly dependent on the bone ingrowth into the ...
Analyzing the impact of human characteristics on the comprehensibility of road traffic signs
(
IEOM Society
, 2018 , Conference Paper)
Traffic safety is one of major challenges facing most communities worldwide. To improve traffic safety, regulating traffic movement through markings, signs, channelization, and others is essential. Traffic signs are used ...

Qatar University is the largest public educational institution in the State of Qatar. The university community has diverse committed faculty who not only teaching but also conducting research studies contributing actively ...
Application of value stream mapping (VSM) for lean and cycle time reduction in complex production environments: a case study
(
Taylor and Francis Ltd.
, 2017 , Article)
The application of VSM is a proven approach for lean-based improvements. Typically, this becomes challenging, when applied for complex production environments. The purpose of this research is to demonstrate, how with some ...
A simulation-optimisation approach for supply chain network design under supply and demand uncertainties
(
Taylor and Francis Ltd.
, 2017 , Article)
We investigate a three-echelon stochastic supply chain network design problem. The problem requires selecting suppliers, determining warehouses locations and sizing, as well as the material flows. The objective is to ...
A Real Case-Based Study Exploring Influence of Human Age and Gender on Drivers’ Behavior and Traffic Safety
(
Springer Verlag
, 2018 , Conference Paper)
The demand for understanding the functional relationship between changes in traffic safety level and human-related factors has increased remarkably due to a steady increase in population and traffic volume. Motor vehicle ...
