A MEASUREMENT CAMPAIGN TO INVESTIGATE THE EFFECT OF USING SOFT RAILPADS ON GROUND-BORNE VIBRATIONS FROM UNDERGROUND RAILWAYS
(
Society of Acoustics
, 2023 , Conference Paper)
Railway networks may run through or beneath populated regions and significant landmarks. Hence, the ground-borne vibration caused by the trains might affect nearby buildings, residents, and the sensitive equipment within ...
Classification of Process Pipework Vibration Using Machine Learning
(
Springer Science and Business Media Deutschland GmbH
, 2024 , Conference Paper)
This paper aims to use a deep convolution neural network (CNN) to classify pipework vibrations. Vibration levels are a good indicator of the risk of vibration-induced fatigue failures (VIF). Vibrations in pipework are very ...
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 ...
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 ...
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), ...
