Phononic crystal surface mode coupling and its use in acoustic Doppler velocimetry
(Elsevier Science Bv, 2016)It is numerically shown that surface modes of two-dimensional phononic crystals, which are Bloch modes bound to the interface between the phononic crystal and the surrounding host, can couple back and forth between the ... -
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 ... -
A Numerical study on the hydrodynamic performance of an immersed foil: Uncertainty quantification of RANS and SPH methods
(Pergamon-Elsevier Science Ltd, 2019)The hydrodynamic characteristics of floating or immersed bodies may be evaluated by a variety of numerical techniques. Although these currently available techniques are well-established for providing valuable information ... -
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 ... -
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 ... -
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 ... -
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, ... -
Investigation of the Effect of Leading-Edge Tubercles on Wingsail Performance
(2020)In this study, effects of leading edge tubercles on a 2013 America’s Cup boat wingsail are investigated by viscous Computational Fluid Dynamics (CFD). Adding tubercles on the leading edge of the sail is inspired by humpback ... -
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 ... -
A Decision Support System for Energy Efficient Ship Propulsion

Real characters, monolithic characters and the Taketa inequality
(World Scientific Publ Co Pte Ltd, 2019)In this paper, we prove that the Taketa inequality, namely the derived length of a finite solvable group G is less than or equal to the number of distinct irreducible complex character degrees of C, is true under some ... -
Numerical Investigation of 2-D Wave Making Characteristics of a Submerged Hydrofoil
(2019)In this study, 2-D wave making characteristics of a submerged hydrofoil has been investigated in a numerical fashion. Experimental data available for different depths of submergence and flow velocities have been compared ... -
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. -
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. ... -
Role of external fields on the nonlinear optical properties of a n-type asymmetric delta-doped double quantum well
(Springer, 2020)The effects of in-growth applied electric fields and in-plane (x-oriented) magnetic fields on the nonlinear optical rectification (NOR), second harmonic generation (SHG) and third harmonic generation (THG) of n-type ... -
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 ... -
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 ... -
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 ... -
