An Acoustic Add-Drop Filter in a Phononic Crystal for High-Sensitivity Detection of Methanol in Ethanol in the Liquid Phase
(Institute of Electrical and Electronics Engineers, 2022)An add-drop filter based on linear waveguides coupled through a ring resonator in a two-dimensional phononic crystal is introduced and its operation in detecting methanol concentration in ethanol is numerically investigated. ... -
Acoustic analysis and measurements of mega yachts during construction
(Royal Institution of Naval Architects, 2019)Noise is a critical parameter for super/mega yachts which can be verified only in the final stage of a mega yacht building project. Although there are more and more advanced methods to predict noise prior to the sea trials, ... -
CFD based vortex generator design and full-scale testing for wake non-uniformity reduction
(Pergamon-Elsevier Science Ltd, 2018)Propeller-induced vibration on ships may originate from separation and wake non-uniformity and can be dealt with stem form redesign, wake adapted propeller design or wake modification devices such as fins, ducts or vortex ... -

A DECISION-MAKING PROCESS FOR SELECTION OF BETTER SHIP MAIN DIMENSIONS WITH THE EEDI REQUIREMENT
(Society of Naval Architects and Marine Engineers, 2022)As the main dimensions of a ship, are vital on the performance of a vessel, major improvements in performance may be achieved by selecting “better” main dimensions. This paper proposes to integrate in the design technique ... -
The effect of impurity position and doping concentration on the binding energies and total optical absorption coefficients in a delta-doped quantum well
(Springer Heidelberg, 2021)In this present work, for different impurity position and ionized doping concentrations, we have theoretically investigated the linear, third-order nonlinear, and total optical absorption coefficients corresponding to the ... -
Evaluation of Aerodynamic Characteristics of Mega-Yacht Superstructures by CFD Simulations
(Soc Naval Architects Marine Engineers, 2020)Air wake distribution around the superstructure of a mega-yacht is a key concern for the designer because of various reasons such as comfort expectations in recreational deck areas, self-noise generation, air pollution and ... -
Evaluation of wind loads on ships by CFD analysis
(Pergamon-Elsevier Science Ltd, 2018)Effect of wind loads on marine structures and ships has to be considered during design. Static and dynamic effects of wind forces and moments are incorporated into the rules and regulations of governing authorities by ... -
Evanescent coupling between surface and linear-defect guided modes in phononic crystals
(Iop Publishing Ltd, 2016)Evanescent coupling between surface and linear-defect waveguide modes in a two-dimensional phononic crystal of steel cylinders in air is numerically demonstrated. When the ratio of scatterer radii to the lattice constant ... -
Fabrication and Characterization of Fe(16)N(2)Micro-Flake Powders and Their Extrusion-Based 3D Printing into Permanent Magnet Form
(Wiley-V C H Verlag Gmbh, 2020)Fe(16)N(2)is a compound with giant saturation magnetization approaching or exceeding that of rare-earth-based permanent magnets. The abundance of its elements and low-cost synthesis of this compound has made it highly ... -
Finite solvable groups with few imprimitive irreducible characters
(World Scientific, 2020)In this paper, we classify all finite solvable groups having at most two imprimitive irreducible characters. © 2022 World Scientific Publishing Company. -
Irreducible constituents of products of characters
(Taylor & Francis Inc, 2019)In this article, we give some results about the relationship between the structure of a finite solvable group G and the kernels of irreducible constituents of the character where chi is an irreducible character of G. For ... -
Low-concentration liquid sensing by an acoustic Mach-Zehnder interferometer in a two-dimensional phononic crystal
(Iop Publishing Ltd, 2015)Mach-Zehnder interferometer formed by liquid-filled linear defect waveguides in a two-dimensional phononic crystal is numerically realized for sensing low concentrations of an analyte. The waveguides in the square phononic ... -

Monolithic characters of real groups
(Taylor & Francis Inc, 2021)In this article, we are concerned with the nonlinear primitive and monolithic characters of a finite real group. We give some criteria for determining whether or not a finite group is real by using its monolithic characters. ... -
Nonlinear optical properties of n-type asymmetric double delta-doped quantum wells: role of high-frequency laser radiation, doping concentration and well width
(Springer Heidelberg, 2020)A numerical investigation on the nonlinear optical rectification, second and third harmonic generation coefficients in asymmetric double n-type d-doped GaAs quantum well is performed in order to identify the influence of ... -
A Note On Derived Length and Character Degrees
(Cambridge Univ Press, 2021)Isaacs and Seitz conjectured that the derived length of a finite solvable group G is bounded by the cardinality of the set of all irreducible character degrees of G. We prove that the conjecture holds for G if the degrees ... -
A Numerical study on the hydrodynamic performance of an immersed foil: Uncertainty quantification of RANS and SPH methods
