This paper concerns the unifying framework to strictly contractive extension problems, which is usually referred to as the band method. The solution to the so-called strictly contractive extension problem in this abstract framework, when applied to a certain concrete case, yields a complete characterization of solutions to the sub-optimal Nehari problem. The sub-optimal Hankel norm approximation p

A common approach to distributed control design is to impose sparsity constraints on the controller structure. Such constraints, however, may greatly complicate the control design procedure. This paper promotes an alternative structure, which is not sparse, yet might nevertheless be well suited for distributed control purposes. The structure appears as the optimal solution to a class of coordinati

Contaminated ground is a severe problem which is present in many countries, and it is of great importance to find efficient solutions to deal with it. In Sweden, there is a trend in the industry to move towards alternate remediation methods and on that scope in-situ bioremediation has received a lot of attention. The main challenge with in-situ bioremediation is to verify that the treatment has th

Two-dimensional laser-induced incandescence (LII) measurements were used for quantitative soot volume fraction ( fv) measurements in methane-air diffusion flames at pressures ranging from 0.1 to 0.5 MPa. Additionally, laser-induced fluorescence (LIF) was used for visualization of polycyclic aromatic hydrocar-bons (PAHs) considered as important soot precursors. A heat and mass transfer-based LII mo

This chapter explores current and prospective reproductive technologies and some of their likely implications for reproductive and family ethics and policymaking. The technologies discussed include uterus transplants, mitochondrial transfer, ectogenesis, the development of in vitro gametes, and solo reproduction. The chapter considers the impact of these developments on the content of concepts suc

What is nationalism? When did it originate and how did it develop throughout the centuries? What types of nationalism have evolved in different sociopolitical settings and why? By addressing these questions, this entry seeks to address the key issues of the conceptualization of nationalism, followed by an analysis of its development in different structural, cultural, and political contexts. The en

Natural habitats are rapidly declining due to urbanisation, with a concomitant decline in biodiversity in highly urbanised areas. Yet thousands of different species have colonised urban environments. These organisms are exposed to novel urban conditions, which are sometimes beneficial, but most often challenging, such as increased ambient temperature, chemicals, noise and light pollution, dietary

Whilst we know quite a bit about organized forms of climate skepticism, very few studies focus on how disorganized climate skeptics seek an underdog position to speak truth to power. Hence, we investigate frank speech as updated ancient forms of truth-telling ‘parrhesia’, in two Swedish empirical sources that strongly question the climate change consensus. The first is a digital space for free spe
