In 2005 a new concept of institutional childcare called "Maison Relais pour Enfants" (MRE) was established in Luxembourg. That can be considered as a flexible answer to an increasingly complex society. The MRE aims to facilitate the reconciliation of work and private life, especially for parents with children aged between 3 and 48 months. This study accompanies the establishment of MRE for members of the University of Luxembourg and the neighborhood around the MRE. As a first step, we interviewed 45 persons (parents, staff and politicians) driven by the need to understand their expectations of the varied functions of the new MRE. The special situation in Luxembourg, a small European country with a highly developed economy, a trilingual education system and one of the ten highest net migration rates in the world, results in many different social environments. First results indicate that there are different ideas about the role of the MRE for giving satisfaction to the children and their parents. Results also show that mothers and fathers handle their Work-Life-Balance depending on their (cross) cultural background; parents often feel "guilty" and they are confronted with a whole range of conflicting thoughts and ideologies of their social environments and related party.

We fix any pair (C,W) consisting of a bicategory and a class of morphisms in it, admitting a bicalculus of fractions, i.e. a “localization” of C with respect to the class W. In the resulting bicategory of fractions, we identify necessary and sufficient conditions for the existence of weak fiber products. [less ▲]

Interference is identified as a critical issue for satellite communication (SATCOM) systems and services. There is a growing concern in the satellite industry to manage and mitigate interference efficiently. While there are efficient techniques to monitor strong interference in SATCOM, weak interference is not so easily detected because of its low interference to signal and noise ratio (ISNR). To address this issue, this paper proposes and develops a technique which takes place on-board the satellite by decoding the desired signal, removing it from the total received signal and applying an Energy Detector (ED) in the remaining signal for the detection of interference. Different from the existing literature, this paper considers imperfect signal cancellation, examining how the decoding errors affect the sensing performance, derives the expressions for the probability of false alarm and provides a set of simulations results, verifying the efficiency of the technique.

In the standard paradigm of isogeometric analysis, the geometry and the simulation spaces are tightly integrated, i.e. the same non-uniform rational B-splines (NURBS) space, which is used for the geometry representation of the domain, is employed for the numerical solution of the problem over the domain. However, there are situations where this tight integration is a bane rather than a boon. Such situations arise where, e.g., (1) the geometry of the domain is simple enough to be represented by low order NURBS, whereas the unknown (exact) solution of the problem is sufficiently regular, and thus, the numerical solution can be obtained with improved accuracy by using NURBS of order higher than that required for the geometry, (2) the constraint of using the same space for the geometry and the numerical solution is particularly undesirable, such as in the shape and topology optimization, and (3) the solution of the problem has low regularity but for the curved boundary of the domain one can employ higher order NURBS. Therefore, we propose to weaken this constraint. An extensive study of patch tests on various combinations of polynomial degree, geometry type, and various cases of varying degrees and control variables between the geometry and the numerical solution will be discussed. It will be shown, with concrete reasoning, that why patch test fails in certain cases, and that those cases should be avoided in practice. Thereafter, selective numerical examples will be presented to address some of the above-mentioned situations, and it will be shown that weakening the tight coupling between geometry and simulation offers more flexibility in choosing the numerical solution spaces, and thus, improved accuracy of the numerical solution.

This paper presents an approach to generalize the concept of isogeometric analysis (IGA) by allowing different spaces for parameterization of the computational domain and for approximation of the solution field. The method inherits the main advantage of isogeometric analysis, i.e. preserves the original, exact CAD geometry (for example, given by NURBS), but allows pairing it with an approximation space which is more suitable/flexible for analysis, for example, T-splines, LR-splines, (truncated) hierarchical B-splines, and PHT-splines. This generalization offers the advantage of adaptive local refinement without the need to re-parameterize the domain, and therefore without weakening the link with the CAD model. We demonstrate the use of the method with different choices of the geometry and field splines, and show that, despite the failure of the standard patch test, the optimum convergence rate is achieved for non-nested spaces.
