This paper presents an overview of the work under development within MAESTRI EU-funded collaborative project. The MAESTRI Total Efficiency Framework (MTEF) aims to advance the sustainability of manufacturing and process industries by providing a management system in the form of a flexible and scalable platform and methodology. The MTEF is based on four pillars: a) an effective management system targeted at process continuous improvement; b) Efficiency assessment tools to support improvements, optimisation strategies and decision support; c) Industrial Symbiosis paradigm to gain value from waste and energy exchange; d) an Internet-of-Things infrastructure to support easy integration and data exchange among shop-floor, business systems and tools.
Epitaxial magnetite thin films with (loo), (1 10) and (1 11) orientation have been deposited by Laser ablation onto substrates with [NaCI] and [Spinel] strudure. X-ray dif£raction revealed pseudomorphic growth for (100) and (11 1) oriented films on MgO (100) and ZnFe,04 (1 11) respectively, whereas films on M&04 showed a high degree of relaxation For films on MgAl,04 and ZnFe204 a significant enhancement of the Verwey-transition temperature compared to bulk material has been observed. The influence of stress on the magnetic anisotropy has been investigated by torque-magnetometry on (1 10) oriented films. Both films on MgO and spinel show an [I101 in plane easy axis, which can be explained by (tensile) stresses in the case of MgO but not in the case of spinel. CEMS pattern indicate out of plane components of the magnetisation for all films. We suggest cation antiphase boundaries, observed by TEM to be responsible for this effect, limiting the magnetic coherence length and thus reducing shape anisotropy.
In quantum Hall edge states and in other one-dimensional interacting systems, charge fractionalization can occur due to the fact that an injected charge pulse decomposes into eigenmodes propagating at different velocities. If the original charge pulse has some spatial width due to injection with a given source-drain voltage, a finite time is needed until the separation between the fractionalized pulses is larger than their width. In the formalism of non-equilibrium bosonization, the above physics is reflected in the separation of initially overlapping square pulses in the effective scattering phase. When expressing the single particle Green's function as a functional determinant of counting operators containing the scattering phase, the time evolution of charge fractionalization is mathematically described by functional determinants with overlapping pulses. We develop a framework for the evaluation of such determinants, describe the system's equilibration dynamics, and compare our theoretical results with recent experimental findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
