A Micromorphic Beam Theory for Beams with Elongated Microstructures
(2020-05)A novel micromorphic beam theory that considers the exact shape and size of the beam’s microstructure is developed. The new theory complements the beam theories that are based on the classical mechanics by modeling the ... -
Mode localization phenomenon in microbeams due to surface roughness
(2018-03)This is the first study on the mode localization phenomenon in microbeams due to surface roughness. A new model for microbeams with rough surfaces is developed. The natural frequencies and mode shapes of cantilever, ... -
Model-Based operational analysis for complex systems: A case study for an integrated control system in a mining industry
(2018)As many manufacturing processes, the mining industry falls within the traditional organization setup, in which the operations are executed in different locations but managed from one master place. This centralized ... -
Model-Based Robust Trajectory Control of 6-DOF Stewart Platform
(ResearchGate, 2013-12)A 6-DOF Stewart platform is designed and constructed as a parallel mechanism that consists of a rigid body moving plate, connected to a fixed base plate through six independent kinematics legs. The mechanism is implemented ... -
Modeling and analysis of a quality traceability framework for phosphate extraction process: evidence from Morocco
(Emerald Publishing Limited, 2021-10)Purpose According to United Nations reports, the worldwide population is expected to reach around 9.6 billion by 2050. This forecasting emphasizes the role of phosphate-based fertilizers for developing sustainable agriculture ... -
Modeling of mechanical resonators used for nanocrystalline materials characterization and disease diagnosis of HIVs
(Springer, 2016)The modeling and performance of mechanical resonators used for mass detection of bio-cells, nanocrystalline materials characterization, and disease diagnosis of human immune-viruses (HIVs) are investigated. To simulate the ... -
Modeling, simulation and design of adaptive 6DOF vehicle stabilizer
(IEEE Xplore, 2019-04)Six Degree of Freedom (6 DOF) parallel manipulators have been utilized for many applications. In this paper, a 6 DOF manipulator is used as a robust vehicle stabilizer in order to fix the orientation of the upper platform. ... -
Modelling and solving the multi-quays berth allocation and crane assignment problem with availability constraints
(Springer, 2020-03)In this work, we are interested in the multi-quays berth allocation and crane assignment problem under availability restrictions. Availability restrictions may arise due weather conditions, or when, for example, cranes ... -
A Modified Particle Swarm Optimization Scheme and Its Application in Electronic Heat Sink Design
(ASME, 2010-06)Particle Swarm optimization (PSO) is a robust stochastic evolutionary computation technique which is based on the movement and intelligence of swarms. In this paper the PSO algorithm is modified to improve its performance ... -
A modified plasticity theory for porous metals
(Wiley Online Library, 1980-05)A plasticity theory for porous metals is proposed. A simple model of a porous materials is analysed by the finite element method. Small strain elastic–plastic analysis provides stress–strain curves, yield stressed and ... -
A modified sequential particle swarm optimization algorithm with future time data for solving transient inverse heat conduction problems
(Taylor and Francis Online, 2011-06)The particle swarm optimization (PSO) method is modified and employed to solve the inverse heat conduction problem. Since the main drawback of PSO in solving inverse problems is its slow convergence, most of the modifications ... -
