Novel structural design of wearable thermoelectric generator with vertically oriented thermoelements
(
Elsevier
, 2022 , Article)
Energy harvesting technology has become important for wearable electronics, where a continuous power supply is essential. Although a wearable thermoelectric generator (TEG) is a promising option in this context, maintaining ...
AIRFOIL-BASED SELF-ADJUSTABLE PIEZOELECTRIC ENERGY HARVESTER IN FLUID-FLOW APPLICATIONS FOR PERFORMANCE OPTIMIZATION
(
Society of Acoustics
, 2022 , Conference Paper)
Piezoelectric vibration energy harvesters can be utilized to harvest kinetic energy from fluid flow for remote sensing applications. Vortex formation behind a bluff body that is coupled to a beam oscillates with two ...
MAGNETORHEOLOGICAL ELASTOMER-BASED FLEXIBLE COUPLING FOR TORSIONAL VIBRATION ISOLATION
(
Society of Acoustics
, 2022 , Conference Paper)
Employing vibration isolation can avoid the detrimental effects of unattenuated torsional vibrations on rotary mechanical equipment. Semi-active vibration isolators can effectively reduce the vibration levels in mechanical ...
A frontier-based managerial approach for relative sustainability performance assessment of the world's airports
(
John Wiley and Sons Ltd
, 2021 , Article)
The sustainability impact of air transportation has become crucial to communities. Airports around the world are forced to be transparent with the society and to declare their sustainability results. As the sustainability ...
Optimization of Viscoelastic Metamaterials for Vibration Attenuation Properties
(
World Scientific
, 2020 , Article)
Metamaterials (MMs) are composites that are artificially engineered to have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ...
Reconstruction of Road Defects from Dynamic Vehicle Accelerations by Using the Artificial Neural Networks
(
Springer Science and Business Media B.V.
, 2023 , Conference Paper)
Monitoring of roads is considered the first step in establishing a successful road maintenance program, which includes scheduling adequate maintenance to a certain road section at the right time. Road monitoring assesses ...
Investigating the effect of using softer rail-pads on ground-borne vibration from underground railways
(
Taylor and Francis Ltd.
, 2023 , Article)
In this study, a series of vibration measurements were performed on a section of one of the lines of the Doha Metro to explore the effect of changing rail-pads from conventional higher stiffness under-rail pads to lower ...
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 ...
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 ...
