Abstract In a simple two-dimensional Ising model for the critical behaviour of magnetic crystals with layer- or surface-like lattice imperfections, the modification of the energy density correlation function and its consequences for the temperature dependence of the specific heat are studied in detail; some results on the spin-spin correlation are ...

A Comprehensive Review of Fractional Calculus in Modeling Real-World Phenomena
Communications on Applied Nonlinear AnalysisFractional calculus, an extension of classical calculus to non-integer orders of differentiation and integration, has garnered significant attention for its remarkable ability to model complex real-world systems. Unlike traditional integer-order models that can oversimplify or neglect certain memory and hereditary properties, fractional calculus ...

Late in the summer of 2013, Elon Musk set the Internet ablaze with a “napkin sketch” of the Hyperloop Alpha, his futuristic vision for mass transit (Christensen, 2013). Musk backed his rudimentary doodle with a 57-page memo where he aimed to keep “numbers to a minimum and avoid formulas and jargon” and apologized, “in advance for [his] loose use of the

1.5 - D convective cloud model with the detailed description of microphysical processes (including 8 categories of cloud particles) is presented in the article. The model is developed for investigation of convective cloud evolution and dangerous phenomena associated with it (thunderstorms, hails and rain storms).

Critical thinking in modelling real-life phenomena based on students’ explorations
2022Critical thinking is one of the most important abilities of International Baccalaureate (IB) students. The present study is based on the works of IB students that are called explorations. Exploration is a part of mature exam, and it is a project, in which students need to solve some real-life problems using mathematical tools.

REAL-SPACE RENORMALIZATION GROUP AND CRITICAL PHENOMENA IN 2-DIMENSIONAL SPIN-1/2 X-Y MODEL
1978A quantum generalization of the Niemeijer and van Leeuwen (N-vL) renormalization group transformation is constructed which allows to study the critical properties (at Tc>0) of a two-dimensional Ising system with a transverse field on a triangular lattice. Explicit calculations are performed in a second order cumulant expansion.
