Abstract:
Regularisation programmes that are intended to legalise the stay of undocumented migrants may provoke public resistance and heated political debates. Governments nevertheless go ahead with such programmes. In the Netherlands, a regularisation programme to settle the legacy of an old Aliens Law, known as the ‘Pardon Regulation’, was implemented in 2007. In this contribution we describe the implementation and outcome of the Pardon Regulation, which led to over 28,000 regularisations. We focus on the question to what extent pitfalls that were experienced in a number of regularisation programmes i

Abstract:
AbstractAlmost all Member States in the European Union currently make use, or in the past have made use of some form of regularisation of irregular immigrants, although to greatly varying degrees, in different ways and as a rule only reluctantly. A distinct feature of recent regularisations has been the shift towards a humanitarian justification of regularisation measures. In this context, regularisation has become reframed as an issue of the protection of irregular migrants’ human rights. As a result, regularisation has to some extent also been turned from a political tool in managing migrati

Abstract:
A system of partial differential equations modelling a van der Waals fluid or an elastic medium with nonmonotone pressure-density relation is studied. As the system changes type, regularisations are considered. The existence of one-dimensional periodic travelling waves, with prescribed average density in a certain range, average velocity and wavelength, is proved. They exhibit layer structure when the regularisation parameter is small. Similarities with the Cahn–Hilliard equation are explored.

Abstract:
Industrial processes are often nonlinear and multivariate and suffer from non-Gaussian noise and outliers in the process data, which cause significant challenges in data-driven modelling. To address these issues, a robust soft-sensing algorithm that integrates Huber’s M-estimation and adaptive regularisations with multilayer perceptron (MLP) is proposed in this paper. The proposed algorithm, called RAdLASSO-MLP, starts with an initially well-trained MLP for nonlinear data-driven modelling. Subsequently, the residuals of the proposed model are robustified with Huber’s M-estimation to improve th

Abstract:
Informal settlements in Tanzania accommodate more than 70% of the urban population. Owing to this, the Tanzanian government has undertaken several initiatives to address the growing size and number of informal settlements. One such initiative is regularisation which addresses security of tenure for residents of these settlements. Most of the people living in informal settlements lack legal land ownership and as a result properties in such settlements have relatively less value and lack security of tenure. Providing security of tenure is believed to encourage investment into informal households

Abstract Neutrino cross-section measurements are often presented as unfolded binned distributions in “true” variables. The ill-posedness of the unfolding problem can lead to results with strong anti-correlations and fluctuations between bins, which make comparisons to theoretical models in plots difficult. To alleviate this problem, one can introduce regularisation terms in the unfolding procedure. These suppress the anti-correlations in the result, at the cost of introducing some bias towards the expected shape of the data. This paper discusses a method using simple linear algebra, which make

Abstract:
Strong gravitational lensing offers a wealth of astrophysical information on the background source it affects, provided the lensed source can be reconstructed as if it was seen in the absence of lensing. In the present work, we illustrate how sparse optimisation can address the problem. As a first step towards a full free-form-lens-modelling technique, we consider linear inversion of the lensed source under sparse regularisation and joint deblending from the lens light profile. The method is based on morphological component analysis, assuming a known mass model. We show with numerical experime

Abstract:
We study noncommutative field theories, which are inherently nonlocal, using a Poincaré-invariant regularisation scheme which yields an effective, nonlocal theory for energies below a cutoff scale. After discussing the general features and the peculiar advantages of this regularisation scheme for theories defined in noncommutative spaces, we focus our attention on the particular case when the noncommutativity parameter is inversely proportional to the square of the cutoff, via a dimensionless parameter η. We work out the perturbative corrections at one-loop order for a scalar theory with quart
