The use of blocking sets in Galois geometries and in related research areas [PDF]

open access: yes, 2012
Blocking sets play a central role in Galois geometries. Besides their intrinsic geometrical importance, the importance of blocking sets also arises from the use of blocking sets for the solution of many other geometrical problems, and problems in related

On BEL-configurations and finite semifields [PDF]

open access: yes, 2014
The BEL-construction for finite semifields was introduced in \cite{BEL2007}; a geometric method for constructing semifield spreads, using so-called BEL-configurations in $V(rn,q)$.

Algebraic solution to a constrained rectilinear minimax location problem on the plane

open access: yes, 2012
We consider a constrained minimax single facility location problem on the plane with rectilinear distance. The feasible set of location points is restricted to rectangles with sides oriented at a 45 degrees angle to the axes of Cartesian coordinates.

Compatibility of the fungus Beauveria bassiana and Trichoplusia ni SNPV against the cabbage looper Trichoplusia ni: crop plant matters

open access: yesPest Management Science, Volume 80, Issue 6, Page 2851-2859, June 2024.
The combined application of a baculovirus (Trichoplusia ni Hübner (Lepidoptera: Noctuidae), T. ni single nucleopolyhedrovirus, TniSNPV) and Beauveria bassiana against the cabbage looper Trichoplusia ni was not more effective compared to singly applied TniSPNV.

A tropical extremal problem with nonlinear objective function and linear inequality constraints [PDF]

open access: yes, 2012
We consider a multidimensional extremal problem formulated in terms of tropical mathematics. The problem is to minimize a nonlinear objective function, which is defined on a finite-dimensional semimodule over an idempotent semifield, subject to linear ...
