Assessing the Ecological Value: Monetizing Process Innovations in Tailored Forming
Advanced Engineering Materials, EarlyView.This article introduces a method for evaluating the sustainability of innovations, even with limited data. The method is illustrated through an analysis of the “Tailored Forming” technology, which explores the impact of sustainability on economic value added.

The Quarterly Journal of Economics, 2004 We estimate the effect of international trade on average laborproductivity at the country level. Our empirical approach relies onsummary measures of trade that, we argue, are preferable on boththeoretical and empirical grounds to the one conventionally used.

A Concerted Effort to Tackle the UK Productivity Puzzle [PDF]
International Productivity Monitor, 2020 The United Kingdom has suffered an extreme version of the "productivity puzzle" – the strong and largely unexplained slowdown in productivity growth among OECD economies since the mid-2000s. In recognition of the challenges that weak productivity growth

A tensor product of representations of UHF algebras arising from Kronecker products [PDF]
arXiv, 2009 We introduce a non-symmetric tensor product of representations of UHF algebras by using Kronecker products of matrices. We prove tensor product formulae of GNS representations by product states and show examples.

Symmetrization of the Berezin Star Product and Multiple Star Product Method [PDF]
, 2000 We construct a multiple star product method and by using this method, show that integral forms of some star products can be written in terms of the path-integral. This method can be applied to some examples. Especially, the associativity of the skew-symmetrized Berezin star product proposed in \cite{SW}, is recovered in large $N$ limit of the multiple ...

Generalized quasi-shuffle products [PDF]
arXiv, 2023 In this paper, we introduce the notion of generalized quasi-shuffle products and give a criterion for their associativity. These extend the quasi-shuffle products introduced by Hoffman, which are often used to describe the stuffle and shuffle product for multiple zeta values. For $q$-analogues of multiple zeta values, the description of an analogue for

Labour Productivity Superstatistics
, 2008 We discuss superstatistics theory of labour productivity. Productivity distribution across workers, firms and industrial sectors are studied empirically and found to obey power-distributions, in sharp contrast to the equilibrium theories of mainstream ...

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components
Advanced Engineering Materials, EarlyView.This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...
