Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical problem. In the literature there are man

In this chapter, we focus on one element of the fragmentation of global climate governance, namely the overlap between the UN climate regime and the World Trade Organization (WTO). With a view to the appraisal question for the ‘architecture’ theme of this volume, we hold that this overlap not only implies benefits, but may also entail significant drawbacks for the development and implementation of

A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw

A virtual reality (VR) experiment with 96 participants was carried out in a Cave Automatic Virtual Environment (CAVE) laboratory at Lund University to provide recommendations on the design of flashing lights at emergency exit portals for road tunnel emergency evacuation. A set of variables were investigated, namely 1) Colour of flashing lights, 2) Flashing rate, 3) The type of light source, 4) The

In this thesis computationally intensive methods are used to estimate models and to make inference for large, spatio-temporal data sets. The thesis is divided into two parts: the first two papers are concerned with video analysis, while the last three papers model and investigate environmental data from the Sahel area in northern Africa. In the first part of the thesis, mixture models are used to

Glass sheets investigated regarding their Po-210 signal originating from indoor radon exposure will have a depth distribution down to about 100 nm. The geometrical probability of implantation into glass of glass-attached radon daughter activity in one alpha recoil event is 50%. A particulate layer on the glass sheet (dust, grease or other particles) will stop the alpha recoil nucleus partly or tot

In order to determine the cardioprotective efficacy of acute reperfusion therapy, assessed as myocardial salvage, in patients with acute coronary occlusion, the final myocardial infarct (MI) size needs to be related to the amount of ischemic myocardium during coronary occlusion, referred to as the myocardium at risk (MaR). There are currently several imaging approaches available for quantification

It has been argued that the decay rates of several radioactive nuclides are slightly lower at Earth's aphelion than at perihelion, and that this effect might depend on heliocentric distance. It might then be expected that nuclear decay rates be considerably lower at larger distances from the sun, e.g., in the asteroid belt at 2-3 AU from where most meteorites originate. If so, ages of meteorites o
