Further development of mathematical description for combined toxicity: A case study of lead–fluoride combination

Toxicology Reports, 2015
In this article, we check and develop further some postulates of the theory and mathematical modeling of combined toxic effect that we proposed earlier [1].

Optimal Segmentation of Glass Shell Structures

Challenging Glass Conference Proceedings, 2016
Monolithic glass shells can be constructed in limited sizes. Segmented shells allow coverage of larger spans. Three shell systems - spherical dome, cylindrical roof and hyperbolic paraboloid were segmented using four different curved glass segment shapes

A quantifying method of microinvestment optimum [PDF]

Amid the controversies around the optimisation criteria and the objective functions when applying mathematical methods in economics, we proposed a method of quantifying a multi-criteria optimum, called critical distance method.

HPG-Tree: An Enhanced B⁺-Tree for Spatial Indexing

IEEE Access
In modern applications such as geographic information systems, game development, and image processing, the demand for efficient two-dimensional spatial indexing is rising exponentially. Traditional approaches like R-tree can suffer from excessive overlap

DESIGN AND EVALUATION OF A HORSE SADDLE USING CAD SOFTWARE

Journal of Industrial Design and Engineering Graphics
The pressure on a horse's back can affect their performance during the equestrian competition. A better pressure distribution on the surface of the horse's back can be obtained using a custom saddle, considering the rider's weight and back anatomy.
