A Fatigue Analysis of a Hydraulic Francis Turbine Runner
(2012-02)In this work, the estimation of crack initiation life of a hydraulic Francis turbine runner is presented. The life prediction is based on the local strain approach to predict the initiation life. First, the analysis is ... -
A Finite Element Approximation of the Stokes Equations
(2011-12)In this work, a numerical solution of the incompressible Stokes equations is proposed. The method suggested is based on an algorithm of discretization by the unstable of Q1 – P0 velocity/pressure finite element ... -
Flexible perovskite based X-ray detectors for dose monitoring in medical imaging applications
(Elsevier, 2018-06)Organometallic halide perovskite materials are attracting considerable interest for high performance photovoltaic and photodetector applications due to their exceptional opto-electronic properties and easy processing ... -
A Foundation for Lorentz Force Based on Vibrating Strings as a Compact Fluid
(Scientific research, 2014-08)Several aspects related with Lorentz force are discussed in the light of the presence of vibrating strings. Strings are considered as a compact, tension and viscosity-free incompressible liquid. The motion of a charge ... -
A hypothesis of series resonance in the white matter for understanding the mechanism of spike-wave seizures
(Elsevier, 2018-03)Generalized epilepsy is accompanied by large-amplitude synchronized spike-wave discharges on electroencephalography. The condition rapidly and synchronously involves most regions of the brain, but the mechanism underlying ... -
Impact of the Housing on the Air Flow and the Thermal Behavior of an Automotive Clutch System
(Scientific Research, 2015-03)New directives and increasing competition push automakers to get better performances (engine power increase), along with mass and size reduction (consumption). These evolutions lead to an increase of the thermal solicitations ... -
Improvement of Open-Circuit Voltage in Organic Photovoltaic Cells with Chemically Modified Indium-Tin Oxide
(Scientific research, 2013-12)The possibility of the increase in open-circuit voltage of organic photovoltaic cells based primarily indium-tin oxide (ITO)/rubrene/fullerene/Al structure by changing the work function of ITO anodes and Al cathodes was ... -
Integration by parts identities in integer numbers of dimensions. A criterion for decoupling systems of differential equations
(Elsevier, 2015-12)Integration by parts identities (IBPs) can be used to express large numbers of apparently different d-dimensional Feynman Integrals in terms of a small subset of so-called master integrals (MIs). Using the IBPs one can ... -
LiFi is a paradigm-shifting 5G technology
(Elsevier, 2018-11)In this paper we will first explain what Light-Fidelity (LiFi) is and argue that it is a 5th Generation (5G) technology. Peak transmission speeds of 8 Gbps from a single light source have been demonstrated, and complete ... -
Linear, Cubic and Quintic Coordinate-Dependent Forces and Kinematic Characteristics of a Spring-Mass System
(2013-09)By combining a pair of linear springs we devise a nonlinear vibrator. For a one dimensional scenario the nonlinear force is composed of a polynomial of odd powers of position-dependent variable greater than or equal three. ... -
A Mathematical Model for Magnetohydrodynamic Convection Flow in a Rotating Horizontal Channel with Inclined Magnetic Field, Magnetic Induction and Hall Current Effects
(2011-06)Closed-form and asymptotic solutions are derived for the steady, fully-developed hydromagnetic free and forced convection flow in a rotating horizontal parallel-plate channel under the action of an inclined magnetic field ... -
Mathematical Modelling of Mass Transfer and Free Convection Current Effects on Unsteady Viscous Flow with Ramped Wall Temperature
(2011-08)An exact analysis of the flow of an incompressible viscous fluid past an infinite vertical plate is conducted taking into account the presence of foreign mass or constant mass flux and ramped wall temperature. The dimensionless ... -

Mazumder Effect of Liquid and Gas Velocities on Magnitude and Location of Maximum Erosion in U-Bend
(Scientific Research, 2012-06)Solid particle erosion is a micromechanical process that is influenced by flow geometry, material of the impacting surface, impact angle, particle size and shape, particle velocity, flow condition and fluid properties. ... -
The Mesoscopic Constitutive Equations for Polymeric Fluids and Some Examples of Viscometric Flows
(2012-02)Constitutive equations for melts and concentrated solutions of linear polymers are derived as consequences of dynamics of a separate macromolecule. The model is investigated for viscometric flows. It was shown that the ... -
Modeling Evaporating Droplets in Complex Unsteady Flows
(Scientific Research, 2012-06)In many applications, a moving fluid carries a suspension of droplets of a second phase which may change in size due to evaporation or condensation. Examples include liquid fuel drops in engines and raindrops or ice-crystals ... -
A New Surfactant Flooding Model for Low Permeability Reservoirs
