BackgroundStudies regarding genetic and clinical characteristics, gender preference, and gonadal malignancy rates for steroid 5-alpha-reductase type 2 deficiency (5-RD2) are limited and they were conducted on small number ...

Geoid undulation prediction using ANNs (RBFNN and GRNN), multiple linear regression (MLR), and interpolation methods: A comparative study

Konakoglu, Berkant; Akar, Alper (Univ Nacional De Colombia, 2021)

This study evaluated different methods for geoid undulation prediction and included two types of artificial neural networks (ANNs) -the radial basis function neural network (RBFNN) and the generalized regression neural ...

GEOID UNDULATION PREDICTION USING GAUSSIAN PROCESSES REGRESSION: A CASE STUDY IN A LOCAL REGION IN TURKEY

Konakoglu, Berkant; Akar, Alper (Acad Sci Czech Republic Inst Rock Structure & Mechanics, 2021)

In order to convert ellipsoidal heights obtained by the Global Navigation Satellite System (GNSS) to orthometric heights, it is necessary to know the distance between the ellipsoidal and geoid surface, called the geoid ...

A Geometric Interpretation of Polarized Light and Electromagnetic Curves Along an Optical Fiber with Surface Kinematics

Ceyhan, Hazal; Ozdemir, Zehra; Gok, Ismail; Ekmekci, F. Nejat (Springer Basel Ag, 2022)

In this study, we research the behavior of a linearly polarized light wave coupling into an optical fiber on a surface in E-3 via geometric phase equations. The geometric phase has applications in many areas from ...

A Geometric view of Magnetic Surfaces and Magnetic Curves

Ozdemi, Zehra; Gok, Ismail; Ekmekc, F. Nejat (INT ELECTRONIC JOURNAL GEOMETRY, 2019)

In the present paper, we approach the magnetic surfaces geometrically. For this aim, we study the problem of constructing a family of magnetic surfaces from a given magnetic field line. We obtain a parametric representation ...

A geometrical and physical interpretation of quaternionic generalized magnetic flux tubes

Ozdemir, Zehra (Pergamon-Elsevier Science Ltd, 2021)

In the present paper, we give a generalization for the magnetic flux tubes. Firstly, we define the flux tube via quaternions. We obtain the magnetic flux canal surfaces and flux tubes by quaternion product of a unit ...

Cali, Ilkay Ozturk (STATE NATURAL HISTORY MUSEUM NAS UKRAINE, 2017)

The types of glandular trichomes and their distribution on the vegetative and reproductive organs of Lamium orientale (syn. Wiedemannia orientalis) are studied for systematic purposes in this paper. Two morphologically ...

Global Warming Can Lead to Depletion of Oxygen by Disrupting Phytoplankton Photosynthesis: A Mathematical Modelling Approach

Sekerci, Yadigar; Petrovskii, Sergei (MDPI, 2018)

We consider the effect of global warming on the coupled plankton-oxygen dynamics in the ocean. The net oxygen production by phytoplankton is known to depend on the water temperature and hence can be disrupted by warming. ...
