PREDICTING ROAD ROUGHNESS PROFILE USING DYNAMIC VEHICLE ACCELERATIONS AND ARTIFICIAL NEURAL NETWORKS
(
Society of Acoustics
, 2022 , Conference Paper)
Road roughness can cause ride discomfort and contribute to the emission of ground-borne noise and vibration. A robust monitoring regime of road roughness is essential for the efficient maintenance of a country's road ...
Fault classification using convolutional neural networks and color channels for time-frequency analysis of acoustic emissions
(
SAGE Publications Inc.
, 2023 , Article)
We present a novel method for real-time fault classification using the time history of acoustic emissions (AEs) recorded from a lab-scale gas turbine operating under normal and faulty conditions across multiple turbine ...
Using probabilistic neural networks for modeling metal fatigue and random vibration in process pipework
(
John Wiley and Sons Inc
, 2022 , Article)
Many experiments are usually needed to quantify probabilistic fatigue behavior in metals. Previous attempts used separate artificial neural network (ANN) to calculate different probabilistic ranges which can be computationally ...
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 ...
Resin bonded bridges in patients with hypodontia: Clinical performance over a 7 year observation period
(
Elsevier
, 2020 , Article)
Purpose
Resin bonded bridges (RBBs) are considered a conservative option in the management of hypodontia. This study targeted to analyze the survival of resin bonded bridges provided to patients with Hypodontia by staff ...
Comparison of SimTraffic and VISSIM Microscopic Traffic Simulation Tools in Modeling Roundabouts
(
Elsevier B.V.
, 2015 , Conference Paper)
Abstract SimTraffic and VISSIM are two microscopic traffic simulation tools that are capable of modeling arterial roads with signalized intersections and roundabouts. This study compares the performance of the two simulation ...

Objective
To investigate the confidence level of final year dental students in Riyadh.
Materials
Cross-sectional study was conducted at four dental colleges in Riyadh (N = 312, 220 and 70,5% responded). Oneway ANOVA and ...
The Urban Regeneration of West-Bay, Business District of Doha (State of Qatar): A Transit Oriented Development Enhancing Livability
(
Elsevier
, 2018 , Article)
Doha, the capital of the State of Qatar, has faced enormous economic growth and rapid urban
transformation over the last few decades. More recently, this has been accentuated by the construction
of major urban public ...
Financial progress and the stability of long-run money demand: Implications for the conduct of monetary policy in emerging economies
(
Elsevier Inc.
, 2009 , Article)
This paper examines whether recent financial changes in three emerging market economies in the Gulf region (Bahrain, the UAE, and Qatar) have distorted the character and the stability of their underlying long-run money ...
Handling data uncertainties in event tree analysis
(
Elsevier B.V.
, 2009 , Article)
Event tree analysis (ETA) is an established risk analysis technique to assess likelihood (in a probabilistic context) of an accident. The objective data available to estimate the likelihood is often missing (or sparse), ...
