Analytical and Numerical Solution of Heat Transfer Equation in Rectangular Composite Fins [PDF]

open access: yesMechanics of Advanced Composite Structures, 2022
Today, the use of composites has received widespread attention due to their special properties that cannot be found in alloys. Kevlar-Epoxy composite is one of the most widely used materials. In this paper, we analyze the heat transfer in rectangular fin

Gaps of size 2, 4, and (conditionally) 6 between successive odd composite numbers occur infinitely often [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The infinite sequence of gaps (first differences) between successive odd composite numbers contains only the numbers 2, 4, and 6. We prove that, for any natural number k, the sequence of gaps contains infinitely many k-tuplets of consecutive gaps all ...
