Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Continued fractions for certain algebraic power series

Journal of Number Theory, 1986
This paper is concerned with the theory of continued fractions over \(\mathbb F_p((x^{-1}))\) (the field of formal Laurent series in \(x^{-1}\) over the field with \(p\) elements) the polynomials in \(x\) playing the role of the integers. Improving and generalizing results of \textit{L. E. Baum} and \textit{M. M. Sweet} [Ann. Math.

Solution of the Fractional Bratu-Type Equation Via Fractional Residual Power Series Method

Tatra Mountains Mathematical Publications, 2020
Abstract In this paper, we present numerical solution for the fractional Bratu-type equation via fractional residual power series method (FRPSM). The fractional derivatives are described in Caputo sense. The main advantage of the FRPSM in comparison with the existing methods is that the method solves the nonlinear problems without ...

Testing of Fractional Cointegration in Macroeconomic Time Series [PDF]

We propose in this article a two-step testing procedure of fractional cointegration in macroeconomic time series. It is based on Robinson’s (1994) univariate tests and is similar in spirit to the one proposed by Engle and Granger (1987), testing ...

Long memory in German energy price indices [PDF]

, 2012
This study examines the long-memory properties of German energy price indices (specifically, import and export prices, as well as producer and consumer prices) for hard coal, lignite, mineral oil and natural gas adopting a fractional integration ...
