Using pavements to generate electricity
(
Elsevier B.V.
, 2019 , Conference Paper)
As part of developing a safe, efficient, and sustainable transportation infrastructure, health monitoring of pavements and bridges, as well as the monitoring of real-time roadway conditions for safety, have become increasingly ...
Literature Review of Advancements in Adaptive Ramp Metering
(
Elsevier
, 2016 , Conference Paper)
Over a period spanning more than 30 years, several ramp metering algorithms have been developed to improve the operation of freeways. Many of these algorithms were deployed in several regions of the world, and field ...
Time Delay and Cost Overrun in Qatari Public Construction Projects
(
Elsevier Ltd
, 2016 , Conference Paper)
This paper investigated cost overruns and delays in Qatari public construction projects. An extensive review of regional and international publications was conducted to get a better understanding of the problem and the ...

(
Elsevier
, 2018 , Conference Paper)
Background Alcohol use is a leading risk factor for death and disability, but its overall association with health remains
complex given the possible protective effects of moderate alcohol consumption on some conditions. ...
An overview of pedestrian signal setting and implementation in the State of Qatar
(
Elsevier B.V.
, 2017 , Conference Paper)
Pedestrian signal control is a main influencing factor on the Level of Service of crossing facilities and on the safety performance considering conflicts with vehicles. In signal design, pedestrian clearance time is a key ...

In this investigation, we aimed to examine the structure of the Driving Behavior Questionnaire (DBQ) across age cohorts spanning 14 to 55 years in the State of Qatar. In addition, we aimed to examine variations in driving ...
Pedestrians' Speed Analysis at Signalized Crosswalks
(
Elsevier B.V.
, 2018 , Conference Paper)
Pedestrian speed is essential for designing signal timings as well as for understanding pedestrian safety issues. This paper presents analysis of three types of pedestrian speeds (entry speed, crossing speed, and exit ...
Experimental detection of localized surface defects in ball bearings using vibration analysis
(
Canadian Acoustical Association
, 2019 , Conference Paper)
This study aimed at the monitoring of bearing health condition, based on vibration measurement. For that purpose, small circular defects were seeded on outer and inner rings of similar bearings, by using the principle of ...
Active control of noise in ventilation ducts
(
Canadian Acoustical Association
, 2019 , Conference Paper)
Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ...
