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. ...
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 ...
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 ...
Towards a sustainable management of end-of-life vehicles in Qatar: A closed-loop circular economy model
(
IEOM Society
, 2018 , Conference Paper)
The end-of-life vehicles (ELVs) are potentially harmful for the environment if they are not processed or recycled in an environmentally friendly manner. In Qatar, the municipality removed almost 13,878 ELVs from different ...
Ridge penalization-based generalized linear model (GzLM) for predicting risky-driving index
(
IEOM Society
, 2018 , Conference Paper)
Road traffic crashes remain one of the major causes of preventable death and injury worldwide. Human behavior is considered one of the main factors leading to such tragic losses. In this paper, we analyze the responses of ...
The performance assessment for the dMEWMA in capturing changes in simple linear profiles
(
IEOM Society
, 2018 , Conference Paper)
In traditional quality control, the quality of product is typically modeled as the univariate or multivariate distribution of the quality parameters. In more recent applications, the quality is modeled using the relationship ...
