A Variational Formulation for Fins with Nonzero Contact Thermal Resistance at the Base

Axioms, 2023
This paper considers the steady-state heat transfer process in a fin with a Robin boundary condition at the base (instead of the usual Dirichlet boundary condition at the base). Robin boundary condition models the effect of the thermal resistance between

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays

Advanced Materials, EarlyView.
An inkjet‐printed liquid crystal droplet array enables compact, low‐cost, single‐shot sensing of the full vectorial light field. Within a single platform, it simultaneously retrieves intensity, polarization, and phase, while dual‐wavelength operation highlights its capability for multi‐wavelength optical field characterization. ABSTRACT Determining the

Trapezoidal approximations of fuzzy numbers with restrictions on the support and core

Proceedings of the 7th conference of the European Society for Fuzzy Logic and Technology (EUSFLAT-2011), 2011
Fuzzy number approximation by trapezoidal fuzzy numbers which preserves the expected interval is discussed. New operators that fulfill additional requirements for the core and support of the fuzzy number are suggested. These supplementary conditions guarantee the proper interpretation of the solution even for very skew original fuzzy numbers.

Approximate Solution of Volterra Integro-Fractional Differential Equations Using Quadratic Spline Function

Қарағанды университетінің хабаршысы. Математика сериясы, 2021
In this paper, we suggest two new methods for approximating the solution to the Volterra integro-fractional differential equation (VIFDEs), based on the normal quadratic spline function and the second method used the Richardson Extrapolation technique ...

Trapezoidal Monte Carlo Integration

, 1990
The approximation of weighted integrals of random processes by the trapezoidal rule based on an ordered random sample is considered. For processes that are once mean-square continuously differentiable and for weight functions that are twice continuously ...
