Transformation To Dual Physical Problems for The Visualization of Abstract Topics
(2015)The Abstract topics are often very difficult to be visualized for the undergraduate students in mathematics, physics and engineering. Those problems could be represented by four fundamental examples; basic vector algebra, ... -
Engineering long shelf life multilayer biologically active surfaces on microfluidic devices for point of care applications
(2016)Although materials and engineered surfaces are broadly utilized in creating assays and devices with wide applications in diagnostics, preservation of these immuno-functionalized surfaces on microfluidic devices remains a ... -
Wormhole solutions sourced by fluids, II: three-fluid two-charged sources
(2016)Lack of a consistent metric for generating rotating wormholes motivates us to present a new one endowed with interesting physical and geometrical properties. When combined with the generalized method of superposition of ... -
Wormhole solutions sourced by fluids, I: Two-fluid charged sources
(2016)We briefly discuss some of the known and new properties of rotating geometries that are relevant to this work. We generalize the analytical method of superposition of fields, known for generating nonrotating solutions, and ... -
Hybridizing a fuzzy multi-response Taguchi optimization algorithm with artificial neural networks to solve standard ready-mixed concrete optimization problems
(2016)In this study, a fuzzy multi-response standard ready-mixed concrete (SRMC) optimization problem is addressed. This problem includes two conflicting quality optimization objectives. One of these objectives is to minimize ... -
Cyclic and heteroclinic flows near general static spherically symmetric black holes
(2016)We investigate the Michel-type accretion onto a static spherically symmetric black hole. Using a Hamiltonian dynamical approach, we show that the standard method employed for tackling the accretion problem has masked some ... -
Astrophysical flows near f (T) gravity black holes
(2016)In this paper, we study the accretion process for fluids flowing near a black hole in the context of f (T) teleparallel gravity. Specifically, by performing a dynamical analysis by a Hamiltonian system, we are able to find ... -
Multifunctional electroactive electrospun nanofiber structures from water solution blends of PVA/ODA-MMT and poly(maleic acid-alt-acrylic acid): effects of Ag, organoclay, structural rearrangement and NaOH doping factors
(2016)Novel multifunctional colloidal polymer nanofiber electrolytes were fabricated by green reactive electrospinning nanotechnology from various water solution/dispersed blends of poly (vinyl alcohol-co-vinyl acetate) ... -
Multifunctional e-spun colloidal nanofiber structures from various dispersed blends of PVA/ODA-MMT with PVP/ODA-MMT, poly(VP-alt-MA) and AgNPs incorporated polymer complexes as electro-active platforms
(2016)This work presented a new approach to fabricate polymer nanocomposites films with nanofiber structures from solution blends of poly(vinyl alcohol) + octadecyl amine-montmorillonite (ODA-MMT) (matrix) with poly(N-vinylpyrrolidone) ... -
Vacuum and nonvacuum black holes in a uniform magnetic field
(2016)We modify and generalize the known solution for the electromagnetic field when a vacuum, stationary, axisymmetric black hole is immersed in a uniform magnetic field to the case of nonvacuum black holes (of modified gravity) ... -
Photodynamic Therapy-Induced Microvascular Changes in a Nonmelanoma Skin Cancer Model Assessed by Photoacoustic Microscopy and Diffuse Correlation Spectroscopy
(2016)One of the main mechanisms of action for photodynamic therapy (PDT) is the destruction of tumor vasculature. We observed the PDT-induced vasculature destruction in a mouse model of skin cancer using two techniques: ... -
Formulations for Minimizing Tour Duration of the Traveling Salesman Problem with Time Windows
(2015)Traveling Salesman Problem with Time Windows (TSPTW) serves as one of the most important variants of the Traveling Salesman Problem (TSP). The main objective functions expressed in the literature of the TSPTW consist of ... -
Humoral immune response and coated or uncoated oxygenators during cardiopulmonary bypass surgery
(2016)Aim: To investigate and compare uncoated and phosphoryl-choline-coated oxygenators in terms of induction of humoral immune response during coronary artery bypass surgery. Methods: A total of 20 consecutive patients who ... -
Integrating features for accelerometer-based activity recognition
(2016)Activity recognition is the problem of predicting the current action of a person through the motion sensors worn on the body. The problem is usually approached as a supervised classification task where a discriminative ... -
New Formulations for the Orienteering Problem
(2016)Problems associated with determining optimal routes from one or several depots (origin, home city) to a set of nodes (vertices, cities, customers, locations) are known as routing problems. The Traveling Salesman Problem ... -
Cyclic and heteroclinic flows near general static spherically symmetric black holes: semi-cyclic flows - addendum and corrigendum
(2017)We present new accretion solutions of a polytropic perfect fluid onto an f(R)-gravity de Sitter-like black hole. We consider two f(R)-gravity models and obtain finite-period cyclic flows oscillating between the event and ... -

Strong gravitational lensing by a charged Kiselev black hole
(2017)We study the gravitational lensing scenario where the lens is a spherically symmetric charged black hole (BH) surrounded by quintessence matter. The null geodesic equations in the curved background of the black hole are ... -
