The mechanical testing and performance analysis of three-dimensionally produced lingual retainers
(Elsevier Inc., 2023)
Background: Introducing three-dimensional (3D) printing has opened new visions in the orthodontic field. This research evaluates three-dimensionally produced orthodontic retainers and their future possible uses. For this ...
Approximations to the 3-D Free Space Scalar Green's Function in Terms of the Taylor Product Theorem
(Institute of Electrical and Electronics Engineers Inc., 2022)
In electromagnetics and acoustics, difficulties are encountered in evaluations of integrals containing the free space scalar Green's Function (, ′). So-called far-field approximations have long been used for obtaining ...
Evaluation of the Remainders of a Class of Series by Using Saddle Point Method
(Institute of Electrical and Electronics Engineers Inc., 2022)
Remainders of various forms of series expressions of a function F(x), which arises frequently in the high frequency solutions of electromagnetic wave radiation and scattering problems, are transformed into some integrals. ...
Iterative histogram equalization using discrete wavelet transform in low-dynamic range
(SPIE, 2023)
A progressive histogram equalization (HE) and contrast enhancement method is proposed in the frequency domain. This method has an iterative structure based on the 6-sigma rule in the low-dynamic range using discrete wavelet ...
3D EM data driven surrogate based design optimization of traveling wave antennas for beam scanning in X-band: an application example
(WINEF, 2022)
In this paper, design and optimization of a microstrip elliptic traveling wave antenna (TWA) are presented for the beam scanning in X-band as an application of 3D data driven surrogate based design optimization technique. ...
Gain Enhancement of a Traditional Horn Antenna using 3D Printed Square-Shaped Multi-layer Dielectric Lens for X-band Applications
(Applied Computational Electromagnetics Society (ACES), 2021)
In this work, gain of a traditional horn antenna is enhanced up to 2.9 dB over X-band using 3D printed square-shaped multi-layer lens. For this purpose, firstly the multi-layer lenses are designed using Invasive Weed ...
Facial Recognition in Hexagonal Domain – A Frontier Approach
(Institute of Electrical and Electronics Engineers Inc., 2023)
Many face-recognition (FR) methods have been proposed thus far. Although FR has achieved wisdom in square pixel-based image processing (SIP) due to many studies, this wisdom has not been transferred to Hexagonal pixel-based ...
Performance boosting of image matching-based iris recognition systems using deformable circular hollow kernels and uniform histogram fusion images
(SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS, 2022)
Identification of people using different biometric data is becoming more important in network society. Biometrics include voice, ears, palms, fingerprints, faces, iris, retina, and hand shapes. Among these features, iris ...
Analytic modeling and comprehensive transverse deflection analysis of elastically restrained piezoelectric actuators with silicone layer
(TAYLOR & FRANCIS INC, 2023)
The impacts of electro-mechanic-fluid parameters on the transverse deflection behavior of the silicone-based piezoelectric diaphragm (SPD) with translational and rotational elastic edges were investigated. The bottommost ...
Fabrication and characterization of chlorhexidine gluconate loaded poly(vinyl alcohol)/45S5 nano-bioactive glass nanofibrous membrane for guided tissue regeneration applications
(John Wiley and Sons Inc, 2023)
Polymeric barrier membranes are used in periodontal applications to prevent fibroblastic cell migration into the cavities of bone tissue and to properly guide the proliferation of tissues. In this study, the fabrication, ...
