Inflection point analysis for Greek seismicity 1900-2006
Demetris T. Christopoulos
The seismicity of Greek region is studied under the prism of ESE & EDE methods for finding the inflection point of cumulative energy released. Main shocks are chosen from 106 years…
On the effective radius of convergence for a given truncated power series expansion
Demetris T. Christopoulos
An effective radius of convergence is defined and computed for any truncated Taylor series. Applications to well known series are performed and is shown that a range of good coinci…
Polynomial regression using trapezoidal rule for computing Legendre coefficients
Demetris T. Christopoulos
We are presenting a method for computing the Fourier coefficients of a given polynomial regression by using the trapezoidal rule for numerical integration. As function basis we use…
Linear Regression without computing pseudo-inverse matrix
Demetris T. Christopoulos
We are presenting a method of linear regression based on Gram-Schmidt orthogonal projection that does not compute a pseudo-inverse matrix. This is useful when we want to make sever…
A simple and numerical stable algorithm for solving the cone projection problem based on a Gram-Schmidt process
Demetris T. Christopoulos
We are presenting a simple and numerical stable algorithm for the solution of the cone projection problem which is suitable for relative small data sets and for simulation purposes…
Developing methods for identifying the inflection point of a convex/concave curve
Demetris T. Christopoulos
We are introducing two methods for revealing the true inflection point of data that contains or not error. The starting point is a set of geometrical properties that follow the exi…
