Predicting air permeability and porosity of nonwovens with image processing and artificial intelligence methods
(Taylor & Francis Ltd, 2020)This study was conducted to investigate the relationship between the fiber distribution and the permeability properties of the hydroentangled nonwoven fabrics in terms of air permeability and porosity. The fiber distribution ... -
An integrated model for estimating energy cost of a tidal current turbine farm
(Pergamon-Elsevier Science Ltd, 2011)A tidal current turbine is a device for harnessing energy from tidal currents and functions in a manner similar to a wind turbine. A tidal current turbine farm consists of a group of tidal current turbines distributed in ... -
Development of an Algorithm to Determine the Liquid Spreading Area of Airlaid Nonwoven Fabrics by Image Processing Method

Ibragimov-Gadjiev operators based on q-integers
(Pushpa Publishing House, 2018)In this paper, we define the q-analogue of the generalized linear positive operators introduced by Ibragimov and Gadjiev in 1970. We study some approximation properties of these new operators, and we show that this sequence ... -
Mathematical programming basis for ship resistance reduction through the optimization of design waterline
(Springer Japan Kk, 2017)It has been more than a decade since Calisal et al. (J Ship Res 46(3):208-213, 2002) presented their concept of wave resistance reduction by allowing an increase in the beam of a ship accompanied by smoothing the shoulders. ... -
Sharp bends of phononic crystal surface modes
(Iop Publishing Ltd, 2015)Sharp bending of surface waves at the interface of a two-dimensional phononic crystal (PnC) of steel cylinders in air and the method of using a diagonally offset cylindrical scatterer are numerically demonstrated by ... -
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 ... -
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 ... -
