The circular economy is promoted by government and industry as an approach to reduce resource consumption while maintaining a high standard of living. In this episode, we explore circular business models that leverage strategies of closing, narrowing or slowing resource loops. This episode is the first of three episodes part of our mini-series on the circular economy. We invite PhD Candidate Kathe

Develops a framework for manufacturing flexibility which illustrates how to obtain consistency from manufacturing strategy to the resource characteristics in the production system. Provides guidance on how to analyse and develop manufacturing flexibility in a corporate decision-making context. Uses the well-known input-transformation-output (ITO) model as a starting point for building the frame-wo

The Book of Hours of Galeazzo Maria Sforza, V. Duke of Milan (Vienna, Austrian National Library, Codex 1856), the so-called Black Hours, is a Flemish illuminated manuscript with silver and gold ink on black coloured parchment from the third quarter of the fifteenth century. The severe deterioration of the parchment by the black colourant resulted in brittleness and numerous losses. This paper desc

The present exploratory study is aimed at the modelling of the chemiluminescence signature of premixed laminar NH3+H2+air flames. The detailed kinetic mechanism of the author was extended by reactions describing the formation and consumption of excited NO2*, NO(A), NH*, and NH2* mostly relying on previous analyses of chemiluminescence processes from the literature. The lowest-lying excited state o

The present work approaches the idea of increasing the efficiency of an industrial steam turbine stage. For this endeavor, an industrial steam turbine stage comprising of prismatic stator and rotor is considered. With the velocity triangles as input, airfoil design is carried out. Firstly, the rotor is redesigned to take care of any incidence issues in the baseline case. In rotor blades, the peak

The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk. The review covered the following categories of study methods: epidemiological studies based on accident and injury data; in-depth accident investigations; naturalistic driving studies; behavioural observations;The report presents the results of a review of the study methods related to vulnerable road user safety that are used today and aims to link accident causation factors to VRU accident risk.

Di-isobutylene has received significant attention as a promising fuel blendstock, as it can be synthesized via biological routes and is a short-listed molecule from the Co-Optima initiative. Di-isobutylene is also popularly used as an alkene representative in multi-component surrogate models for engine studies of gasoline fuels. However, there is limited experimental data available in the literatu

The multimedia era has started. The migration of computer (packet oriented) and telephony (circuit switched) networks in combination with an explosive development of new services, creates a mass market for public broadband communication. There are no reasons foreseen why these kinds of services should not go mobile. Future customers will not treat a mobile access differently than a fixed access to

Reactive settling is the process of sedimentation of small solid particles in a fluid with simultaneous reactions between the components of the solid and liquid phases. This process is important in sequencing batch reactors (SBRs) in wastewater treatment plants. In that application the particles are biomass (bacteria; activated sludge) and the liquid contains substrates (nitrogen, phosphorus) to b

Tunnel FETs (TFETs) have been identified as the most promising steep slope devices for ultralow power logic circuits. In this paper, we demonstrate in-plane InAs/Si TFETs monolithically integrated on Si, using our recently developed template-assisted selective epitaxy approach. These devices represent some of the most scaled TFETs with dimensions of less than 30 nm, combined with excellent aggrega

Background: Unexpected prolongation of first-line coagulation tests, including activated partial thromboplastin time (APTT), should trigger further work-up by performing mixing tests to elucidate the underlying cause, direct further specific testing and clarify their possible clinical impact. The aim of our study was to assess whether methodological diversity has any impact on the APTT mixing test

A memetic framework for optimal inverse design is proposed by combining a local gradient-based procedure and a robust global scheme. The procedure is based on method-of-moments matrices and does not demand full inversion of a system matrix. Fundamental bounds are evaluated for all optimized metrics in the same manner, providing natural stopping criteria and quality measures for realized devices. C
