Borehold trajectory between two consecutive survey points is approximated by using a curve defined in three dimensional space. Mathematically, this curve is envisioned to be the course swept by the end points of the vectors originating from the wellhead. These vectors are represented by a single vector function. Three components of the vector function are defined as a second degree polynomical function of the measured depth (MD). These second degree functions represent the change in North-South, East-West, and the true vertical depth (TVD) co-ordinates of any point on the well course. The second degree polynomical relation is verified by using the data from a small scale curved hole model measurements as well as the data from the field measurements.

A model for the computation of quantum billiards with arbitrary shapes Erhan, Inci M.; Taşeli, Hasan (Elsevier BV, 2006-10-01) An expansion method for the stationary Schrodinger equation of a three-dimensional quantum billiard system whose boundary is defined by an arbitrary analytic function is introduced. The method is based on a coordinate transformation and an expansion in spherical harmonics. The effectiveness is verified and confirmed by a numerical example, which is a billiard system depending on a parameter.
A Survey on Spacetime Geometries and Relativistic Models Okutmuştur, Baver (null; 2019-12-23) Our analysis starts with the flat geometry, so-called Minkowski spacetime, and follows by further generalizations on specific spherically symmetric geometries whose metric elements describe solutions to the Einstein’s field equation. Next the relativistic models originated from the conservation form of the energy momentum tensor relation on these particular examples of spacetime geometries are presented. Finally we introduce certain properties of these models of interests and hence provide a conclusion ...
An Efficient Semianalytical Method for Hypersingularity Treatment Over Curved Patches Selcuk, G.; Koç, Seyit Sencer (2017-05-01) In this communication, we propose an efficient method to evaluate hypersingular integrals defined on curved surfaces. First an exact expression for hypersingular kernel is derived by projecting the integral on curvilinear element on a flat surface. Next singularity subtraction employed, where the singular core is hypersingular and the remaining part is weakly singular. The singular core is evaluated analytically using finite part interpretation and the remaining weakly singular part is evaluated numerically...
A physical model for dimensional reduction and its effects on the observable parameters of the universe Karaca, Koray; Bayın, Selçuk; Department of Physics (2005) In this thesis, assuming that higher spatial dimensions existed only during the inflationary prematter phases of the universe, we construct a (1+D)-dimensional (D>3), nonsingular, homogeneous and isotropic Friedmann model for dimensional reduction. In this model, dimensional reduction occurs in the form of a phase transition that follows from a purely thermodynamical consideration that the universe heats up during the inflationary prematter phases. When the temperature reaches its Planck value Tpl,D, which ...
An integral equation approach to the computation of nonlinear fields in electrical machines Kükrer, Osman; Ertan, H. Bülnet (Institute of Electrical and Electronics Engineers (IEEE), 1988-7) A numerical method based on an integral equation formulation, for the computation of nonlinear magnetostatic field, in two dimensions in cylindrical polar coordinates is given. The correctness of the method is illustrated by solving two linear two-dimensional magnetic field problems which have readily available analytical solutions. The dependence of the accuracy of the solution on the number and distribution of the meshes is studied on these examples. The method is then applied to the computation of the no...
