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

On approximation numbers of composition operators
Journal of Approximation Theory, 2012 We show that the approximation numbers of a compact composition operator on the weighted Bergman spaces $\mathfrak{B}_ $ of the unit disk can tend to 0 arbitrarily slowly, but that they never tend quickly to 0: they grow at least exponentially, and this speed of convergence is only obtained for symbols which do not approach the unit circle.

A Note on the Compositeness of Numbers [PDF]
Proceedings of the American Mathematical Society, 1957 The "compositeness" of the number n = pclpa2 a * * pam iS defined by Q(n) =a1+a2?+ +Ofa,. If the integers be partitioned into two classes Eo and E1 according to whether Q(n) =0, 1 (mod 2), and Eo(x), El(x) be the corresponding counting functions, it follows that Ei(x) = (x/2) +error.

The crossing number of composite knots [PDF]
Journal of Topology, 2009 It is a very old conjecture that the crossing number of knots is additive under connected sum. In other words, if K#K' is the connected sum of knots K and K', then does the equality c(K#K') = c(K) + c(K') hold? We prove that c(K#K') is at most c(K) + c(K') and at least (c(K) + c(K'))/152.

Adaptive Speaker Recognition Based on Hidden Markov Model Parameter Optimization
IEEE Access, 2020 The Hidden Markov Model (HMM) is a widely used method for speaker recognition. During its training, the composite order of the measurement probability matrix and the number of re-evaluations of the initial model affect the speed and accuracy of a ...
