Combining Stage-Gate™ model using Set-Based concurrent engineering and sustainable end-of-life principles in a product development assessment tool

The challenge to develop sustainable products increases as resources becomes scarcer. Lifecycle Assessment (LCA) and Ecodesign have emerged to diminish product environmental impact from material gaining to disposal. LCA methods and tools, however, were not conceived to spur product design activities and decisions towards sustainable End-of-life (EoL) product conception, while Ecodesign requires ma

Exploring ecosystem network analysis to balance resilience and performance in sustainable supply chain design

Sustainable supply chain design can be performed using optimisation strategies for minimising environmental impacts while maximising profit. It is not clear how such strategies influence the resilience of a supply chain – its ability to handle disturbances without compromising its function. This research used the ecosystem network analysis (ENA) to evaluate the resilience during the design of a su

Towards Regenerative Supply Networks : a design framework proposal

Anthropocentrism and disciplinary research have not led to effective solutions to sustainability problems. A shift is required towards biocentric, transdisciplinarity-based solutions, to mitigate rebound effects and unintended, negative effects. In the field of Sustainable Supply Network Design, such shift implies on developing resilient solutions that maximize environmental benefits instead of mi

Sustainable design and its interfaces : an overview

One of the best opportunities to deliver sustainable principles is during the product development process. To be considered truly sustainable, a product must be designed respecting three dimensions: economic, environmental and societal, in a systemic approach. From this perspective, this paper aims to overview sustainable product design and interfaces with its supporting processes, taking advantag

Sex and gender publications in brain health : a mapping review of the Asia-Pacific region

INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gend

Fundamental bounds on the performance of monochromatic passive cloaks

Fundamental bounds on the performance of monochromatic scattering-cancellation and field-zeroing cloaks made of prescribed linear passive materials occupying a predefined design region are formulated by projecting field quantities onto a sub-sectional basis and applying quadratically constrained quadratic programming. Formulations are numerically tested revealing key physical trends as well as adv

Optimal Planar Electric Dipole Antennas: Searching for antennas reaching the fundamental bounds on selected metrics

Considerable time is often spent optimizing antennas to meet specific design metrics. Rarely, however, are the resulting antenna designs compared to rigorous physical bounds on those metrics. Here, we study the performance of optimized planar meander line antennas with respect to such bounds. Results show that these simple structures meet the lower bound on the radiation quality factor (Q-factor)

Physical Bounds for Antennas Above a Ground Plane

Physical limitations of antennas above infinite perfect electric conductor (PEC) ground planes are determined using the stored electromagnetic energy. Stored energies are computed with the method of moments (MoM) and the image theory. Convex optimization is used to derive the G/Q ratio and Q-factor for a reference geometry, and the results are compared for different antenna types.

Estimation of Spherical Wave Coefficients from 3D Positioner Channel Measurements

Electromagnetic vector spherical waves have been used recently to model antenna-channel interaction and the available degrees of freedom in multiple-input-multiple-output (MIMO) systems. However, there are no previous accounts of a method to estimate spherical wave coefficients from channel measurements. One approach for this, using a 3-D positioner, is presented and analyzed in this letter. Measu

Physical bounds and optimal currents on antennas

Physical bounds on the directivity Q-factor quotient and optimal current distributions are determined for antennas of arbitrary shape and size using an optimization formulation. A variational approach offers closed form solutions for small antennas expressed in the polarizability of the antenna structure. Finite sized antennas are solved using Lagrangian parameters in a method of moments formulati

Seamless PID–MPC Hybrid Control

It is common that PID control loops function satisfactorily most of the time, but that they have issues with violating input, state, or output constraints. While MPC solves this problem in principle, it is in practice not straightforward to replace a functioning PID controller with an MPC implementation. This is particularly true for loops that are critical to plant operation, where stops associat

Training pathologists to assess stromal tumour-infiltrating lymphocytes in breast cancer synergises efforts in clinical care and scientific research

A growing body of research supports stromal tumour-infiltrating lymphocyte (TIL) density in breast cancer to be a robust prognostic and predicive biomarker. The gold standard for stromal TIL density quantitation in breast cancer is pathologist visual assessment using haematoxylin and eosin-stained slides. Artificial intelligence/machine-learning algorithms are in development to automate the stroma

Resisting Democratisation : Arguments Against Female Enfranchisement Among Members of the Swedish Parliament 1866–1918

In this contribution, we analyse the parliamentary minutes debating the issue of women’s voting rights in Sweden from the start of the two-chamber parliament in 1866 until 1918, when women were finally granted voting rights on the same terms as men. We find that most arguments belonged to one of two broad categories: those that were against women’s suffrage as a matter of principle, and those that
