Usage statistics and usage patterns on the NorduGrid: Analyzing the logging information collected on one of the largest production Grids of the world

The Nordic Grid facility (NorduGrid [1]) came into operation during summer 2002 when the Scandinavian ATLAS HEP group started to use the Grid for the ATLAS Data Challenges (DC) and was thus the first Grid ever contributing to an ATLAS production. Since then, the Grid facility has been in continuous 24/7 operation. NorduGrid is being used by a growing set of active users from various scientific are

Improving OFDM: Multistream faster than Nyquist signaling

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

Föräldrar i arbete. En könskritisk undersökning av småbarnsföräldrars arbetsrättsliga ställning (Parents at work. A gender-critical study on the position of parents of young children in labour law)

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

Simulation of gain in quantum cascade lasers

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

Governing the Climate: New Approaches to Rationality, Politics and Power

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
