, 2009 p. 525-535A new approach is proposed for shape optimization of shell surfaces, where requirements on the aesthetic aspect and the constructability as well as the structural rationality are simultaneously considered in the problem formulation. The surface

Geometric Investigation of Three Thin Shells with Ruled Middle Surfaces with the Same Main Frame
Structural Mechanics of Engineering Constructions and BuildingsIt is proved and illustrated that by taking the main frame of the surface, consisting of three plane curves placed in three coordinate planes, three different algebraic surfaces with the same rigid frame can be designed.

PythagorasDeveloping structure sense is an important part of learning algebra. We investigated learners’ structure sense of algebraic expressions involving brackets. This led us to propose the constructs surface structure sense and systemic structure sense.

On the Integrability of the SIR Epidemic Model with Vital Dynamics
Advances in Mathematical Physics, 2020 In this paper, we study the SIR epidemic model with vital dynamics Ṡ=−βSI+μN−S,İ=βSI−γ+μI,Ṙ=γI−μR, from the point of view of integrability. In the case of the death/birth rate μ=0, the SIR model is integrable, and we provide its general solutions by ...

A Graphical Method for Great Circle Routes
Polish Maritime Research, 2017 A great circle route (GCR) is the shortest route on a spherical earth model. Do we have a visual diagram to handle the shortest route? In this paper, a graphical method (GM) is proposed to solve the GCR problems based on the celestial meridian diagram ...

Estimating Nielsen Numbers on Wedge Product Spaces
Fixed Point Theory and Applications, 2008 Let f:X→X be a self-map of a finite polyhedron that is an aspherical wedge product space X. In this paper, we estimate the Nielsen number N(f) of f.
