A problem with parameter for the integro-differential equations

Mathematical Modelling and Analysis, 2021
The article proposes a numerically approximate method for solving a boundary value problem for an integro-differential equation with a parameter and considers its convergence, stability, and accuracy. The integro-differential equation with a parameter is

A fractionally loaded boundary value problem two-dimensional in the spatial variable [PDF]

Қарағанды университетінің хабаршысы. Математика сериясы, 2023
In the paper, the boundary value problem for the loaded heat equation is solved, and the loaded term is represented as the Riemann-Liouville derivative with respect to the time variable. The domain of the unknown function is the cone.

A non-local problem for a loaded mixed-type equation with a integral operator

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2016
We study the existence and uniqueness of the solution of non-local boundary value problem for the loaded elliptic-hyperbolic equation $$ u_{xx} + \mathop{\mathrm{sgn}} (y) u_{yy} + \frac{1 - \mathop{\mathrm{sgn}} (y)}{2} \sum\limits_{k = 1}^n {R_k}(x, u ...

Bed-Load Transport Equation on Arbitrarily Sloping Beds [PDF]

Journal of Hydraulic Engineering, 2008
This work presents a simple tool to evaluate bed-load transport intensity and direction on arbitrarily sloping beds with local longitudinal and transversal inclinations up to 25° and in the case of uniform sediments and low values of the applied Shields stress.

Constitutive equation of butter at static loading [PDF]

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2014
This study focuses on the constitutive modelling of finite deformation in the commercially obtained butter (composition is 83 % of milk fat) at the temperature 17–20 °C. The specimens from the butter (height L0=14.6 mm and diameter 20 mm) have been compressed between two parallel metal plates at a fixed crosshead speed 20 mm/min using of the testing ...
