Abstract in UndeterminedThe topology optimization problem is formulated in a phase-field approach. The solution procedure is based on the Allan–Cahn diffusion model where the conservation of volume is enforced by a global constraint. The functional defining the minimization problem is selected such that no penalization is imposed for full and void materials. Upper and lower bounds of the density f
In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metac

In the present work we have selected a collection of statistical and mathematical tools useful for the exploration of multivariate data and we present them in a form that is meant to be particularly accessible to a classically trained mathematician. We give self contained and streamlined introductions to principal component analysis, multidimensional scaling and statistical hypothesis testing. Wit
This study compares students' experiences of two types of criteria-based assessment: in text commentary and rubric-articulated feedback, in an assessment design combining the two feedback channels. The main aim is to use students' responses to shed light on how feedback strategies for formative assessment can be optimised. Following action research methodology, the study discusses key categories o
We consider time-dependent thermal fluid structure interaction. The respective models are the compressible Navier–Stokes equations and the nonlinear heat equation. A partitioned coupling approach via a Dirichlet–Neumann method and a fixed point iteration is employed. As a reference solver, a previously developed efficient time-adaptive higher-order time integration scheme is used. To improve on t

Sustainable business model innovation is increasingly viewed as a lever for systems change for sustainability across businesses and industries. Banks hold a unique intermediary role in sustainable development, but also have a difficult position after the 2008 financial crisis. This paper aims to explore business models for sustainability in the service industry, particularly banking. It explores t
Perennial grain crops are gaining increased attention from researchers as one possible solution to agriculture’s many sustainability challenges. In the Sub-Saharan African context, perennial varieties of crops such as sorghum, rice, and pigeon pea have potential to provide numerous benefits for smallholder farmers. The introduction and adoption of new crops and practices is however a complex proce
The demands on library services are quickly changing in a continually updating digital age. This increases the importance of a good understanding of the needs and demands of the users. In order to sample and follow the change in user needs library organisations analyse their efforts using a series of different methods. In a recent survey distributed to all 301 European LIBER university libraries,
