Numerical investigations have been carried out on bed load sediment transport in a river with uniform steady flow. The Lagrangian method is applied to develop the numerical model. The numerical method is a modified and improved version of the latest introduced Smoothed Particle Hydrodynamic schem...

The material removal rate in the wire sawing technology depends on several features of the used abrasives and the complex process of particle movement and interaction inside the kerf. To investigate these micro-mechanical aspects of the wire sawing process, a numerical model is developed in the p...

A flow biosensor for the detection of toxicity in water using the ammonia-oxidizing bacterium (AOB) Nitrosomonas europaea as a bioreceptor and a polymeric membrane ammonium-selective electrode as a transducer is described. The system is based on the inhibition effects of toxicants on the activity...

A quartz crystal microbalance (QCM) biosensor with nanogram sensitivity has been constructed through a reasonable designing and biological processing of the piezoelectric quartz crystals. Due to its highly sensitivity, real time detection and low cost, the proposed QCM biosensor has a promising p...

In this study, we explored magnetic nanoparticles translocating through a nanopore in the presence of an inhomogeneous magnetic field. By detecting the ionic current blockade signals with a silicon nitride nanopore, we found that the translocation velocity that is driven by magnetic and hydrodyna...

Concrete filled double skin circular tubular (CFDST) members consist of double concentric circular steel tubes with concrete sandwiched between them. Having hollow cross-section, CFDST members are lighter than ordinary concrete filled steel tubular (CFT) members, which have solid cross-sections. ...

This paper presents the development and validation of finite element (FE) models to simulate the behavior of a novel composite shear wall system consisting of two skins of profiled steel sheeting and an infill of concrete under in-plane loadings. This walling system has potential to be used as sh...

This paper proposes the modeling and control of vibrations in wind turbines due to change in the rotational speed of the blades. Structural and/or electrical faults occurring in a wind turbine may lead to fluctuations of the angular velocity of the rotor blades. The impact of these fluctuations o...
