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 ...
Optimizing national resource usage through the integration of University shuttle service with the public rail: The case study in Qatar University
(
IEOM Society
, 2018 , Conference Paper)
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 ...
Model-Based Analysis of Spur Gears' Dynamic Behavior in the Presence of Multiple Cracks
(
Hindawi Limited
, 2018 , Article)
Early detection of tooth cracks is crucial for effective condition-based monitoring and decision making. The scope of this work was to bring more insight into the vibration behavior of spur gears in the presence of single ...
Current status of tissue engineering in the management of severe hypospadias
(
Frontiers Media S.A.
, 2018 , Article Review)
Hypospadias, characterized by misplacement of the urinary meatus in the lower side of the penis, is a frequent birth defect in male children. Because of the huge variation in the anatomic presentation of hypospadias, no ...
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 ...
Towards sustainable society: Design of food waste recycling machine
(
IEOM Society
, 2018 , Conference Paper)
Qatar is one of the top 10 countries in the world in terms of per capita food waste; which ranges from 584 to 657 kilograms per year. The combination of high food consumption rate and very low food waste recycle rate, ...
Slip suppression in prosthetic hands using a reflective optical sensor and MPI controller
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
Prosthetic hands have greatly evolved in mechatronic, robotic and control aspects. However, occasional accidents might happen due to excessive grip force or the breaking of contact due to slip. Fast transient slip events ...
Development of an active noise control earplug
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
Active Noise Control (ANC) is used in controlling low frequency noise where passive control is ineffective. This paper presents the main results obtained from the development of an active noise control earplug for use in ...
