Objectivity and Evaluation [PDF]

open access: yes, 2019
I this article, I introduce the notion of pluralism about an area, and use it to argue that the questions at the center of our normative lives are not settled by the facts -- even the normative facts. One upshot of the discussion is that the concepts of

Anamorphic images on the historical background along with their classification and some selected examples

open access: yesTechnical Transactions, 2017
Art based on optical illusions has accompanied the everyday life of a human being since ancient times, until today. Primarily, it played a specific role as an artistic game and manifested the artists’ own mastery, while often playing the serviceable role

An upwind-based scheme for solving the oblique derivative boundary-value problem related to physical geodesy

open access: yesJournal of Geodetic Science, 2015
The paper presents a novel original upwindbased approach for solving the oblique derivative boundary value problem by the finite volume method. In this approach, the oblique derivative boundary condition is interpreted as a stationary advection equation ...

An application of Groebner bases to planarity of intersection of surfaces [PDF]

open access: yes, 2009
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in ${\bf R}^3$. We specially considered plane sections of certain type of conoid which has a cubic egg curve as one of the directrices ...
