Mazo's concept of Faster Than Nyquist signaling is extended to pulse trains that modulate adjacent subcarriers, in a manner similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission system achieves the isolated pulse error performance. Systems with at least twice the spe

Popular Abstract in Swedish Avhandlingen behandlar förvärvsarbetande småbarnsföräldrars arbetsrättsliga ställning. Utgångspunkten i avhandlingen är att arbetsrättens regler om föräldraskap, trots sitt tämligen starkt formulerade rättighetsskydd, i praktiken har en förhållandevis svag normativ position i arbetslivet och i arbetsrätten. Föräldraskapsreglernas svaga position kan förklaras som ett resThis dissertation deals with the position of working parents in labour legislation and the protection. The starting point for the thesis is that the rules in labour law concerning employees? parenthood, despite the fairly strongly formulated protection of their rights, in practice have a relatively weak normative position in working life and in labour law. The weakness of the rules on parenthood c
The gain profile of a quantum cascade laser is strongly influenced by the lifetime of the carriers in the upper and lower laser state. The quantitative description of gain within the concept of nonequilibrium Green's functions allows for a detailed understanding of various features affecting the gain spectrum: Compensation effects between scattering processes in the upper and lower laser level, re
Despite a growing interest in critical social and political studies of climate change, the field remains fragmented and diffuse. This is the first volume to collect this body of scholarship, providing a key reference point in the growing debate about climate change across the social sciences. The book provides a new set of insights into the ways in which climate change is creating new forms of soc
Scanning tunneling microscopy induced luminescence (STML) has been used to investigate individual self-assembled InP quantum dots overgrown with GaInP. We will present results correlating the surface morphology with the optical properties of single dots. In particular, the strain induced energy-shift of the dot emission with increasing cap layer thickness and its relation to the overgrowth will be
