A theoretical and experimental study of fast lower bounds for the two-dimensional bin packing problem
( EDP Sciences , 2018 , Article)We address the two-dimensional bin packing problem with fixed orientation. This problem requires packing a set of small rectangular items into a minimum number of standard two-dimensional bins. It is a notoriously intractable ... -
A three dimensional extended Arlequin method for dynamic fracture
( Elsevier B.V. , 2015 , Article)We propose a concurrent multiscale method for fracture coupling two three-dimensional continuum domains. Fracture in both domains is treated by the extended finite element method. The coupling is based on the Arlequin ... -
A two-level optimization approach for robust aircraft routing and retiming
( Elsevier Ltd , 2017 , Article)We investigate the Robust Aircraft Routing and Retiming Problem that is defined as follows. Given a set of flight legs to be served by a set of aircraft fleets, together with a tentative schedule, the problem requires ... -
A validated design methodology for a closed-loop subsonic wind tunnel
( Elsevier Ltd , 2014 , Article)A systematic investigation into the design and simulation of flow parameters in a closed-loop wind tunnel was carried out using Computational Fluid Dynamics (CFD). The analytical model for estimating pressure losses were ... -
A vortex-induced vibration-based self-tunable airfoil-shaped piezoelectric energy harvester for remote sensing applications in water
( Elsevier , 2023 , Article)With growing innovations on the Internet of Things capabilities, automated monitoring and remote sensing applications have become important in the modern world. However, with thousands of distributed sensors and wireless ... -
Abandoned petroleum wells as sustainable sources of geothermal energy
( Elsevier Ltd , 2014 , Article)A reliable heat transfer model was developed to determine the performance of a double pipe heat exchanger retrofitted to an abandoned petroleum well. The proposed model is compared against an analytical heat transfer model ... -
Abnormal release of toxic gases from natural gas processing plants
( American Society of Mechanical Engineers (ASME) , 2001 , Conference Paper)Qatar, one of the Arabian Gulf States, possesses one of the world's largest non-associated gas fields. Most of the country's development plans are based on the preparation of natural gas for export and local use. Under ... -
Accurate prediction of dynamic viscosity of polyalpha-olefin boron nitride nanofluids using machine learning
( Elsevier , 2023 , Article)This study focuses on predicting the dynamic viscosity of nanofluids, specifically Polyalpha-Olefin-hexagonal boron nitride (PAO-hBN) using machine learning models. The primary goal of this research is to assess and contrast ... -
Active agents loaded extracellular matrix mimetic electrospun membranes for wound healing applications
( Editions de Sante , 2021 , Article)Achieving the healing of chronic diabetic ulcers, burn wounds and large traumatic wounds is a major clinical challenge. A variety of approaches have been undertaken to generate skin substitutes, wound healing patches or ... -
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 ... -
Active Noise Control in Workplaces
( Springer , 2016 , Article)Excessive workplace noise affects human health, safety, and comfort. Noise control in the workplace becomes necessary if the noise exceeds the level specified by noise regulations. This paper presents examples of active ... -
Active Vibration Isolation System (AVIS) using a Voice Coil Actuator to improve Free Space Optics Communication
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In Free Space Optic communication (FSOC), transmitter and receiver's alignment is vital to maintain the line of sight during the whole communication period. This is critical in data transmission over a long-distance. ... -
Adaptive Electromagnetic Vibration Absorber for a Multimode Structure
( Assoc. of Mechanical Eng. and Technicians of Slovenia , 2022 , Article)All structures experience vibrations due to external dynamic force excitations, such as earthquakes and wind loadings. At resonance, the impact of this natural dynamic force on structures may lead to structural failures. ... -
An adaptive step-down procedure for fault variable identification
( Taylor & Francis , 2015 , Article)In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ... -
