This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculat
Popular Abstract in Swedish Grönsaker andas och efter skörd innebär det att de börjar brytas ner. Broccoli är en grönsak som bryts ner snabbt på grund av sin höga andningshastighet, även kallad respirationshastighet. För att förlänga hållbarheten förpackas den ofta i plastförpackningar med syfte att förhindra nedbrytningen och sänka andingshastigheten. Plastfilmer har olika genomsläpplighet för gaThe modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package. This thesis has focused on the MAP of broccoli and the effect of the packa
2,8-Dihalo substituted analogues of Tröger’s base were prepared via the Tröger’s base condensation reaction. These compounds were used as synthetic intermediates for the preparation of otherwise inaccessible functionalized Tröger’s base analogues. Based on 2,8-diiodo-4,10-dimethyl-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine, a mild room temperature protocol for the introduction of terminal func
Efficient variability management is a key issue in large-scale product line engineering, where products with different propositions are built on a common platform. Variability management implies challenges both on requirements engineering and configuration management. This paper presents findings from an improvement effort in an industrial case study including the following contributions: problem
Biogas production is growing and there is an increasing demand for upgraded bio- gas, to be used as vehicle fuel or injected to the natural gas grid. To enable the efficient use of biogas in these applications the gas must be upgraded, i.e. the carbon dioxide, which constitutes a large part of the raw biogas from the digester, must be separated from the methane. This report aims to evaluate the bi
Hemp (Cannabis sativa) is an agricultural crop that can be used as a building material in combination with lime and cement. A composite building material that combines a cementitious binder (building limes and cement) with hemp shives, the woody core of the hemp stalk is generally referred to as hemp concrete (HC). However, industrial facilities to separate hemp shives and fibres are currently not
Universities have become important components of the national innovation systems in innovation driven economies. To strengthen the university related flow of mainly technological knowledge into commercialized products many European countries have followed the American example and changed from an inventor-ownership system to a university-owned system (Genua & Rossi, 2011). Today most European c

Two different frequency doubling power amplifier topologies have been compared, one with differential input and one with single-ended, both with single-ended output at 60 GHz. The frequency doubling capability is valuable from at least two perspectives, 1) the high frequency signal is on the chip as little as possible 2) the voltage controlled oscillator and power amplifier are at different freque
Popular Abstract in Swedish Denna avhandling kan delas in i två delar. Den första delen behandlar en analys av en vanlig parameter estimations algoritm - Rekursiv Minska Kvadrat (RMK) algoritmen. Denna algoritm används ofta inom tekniska tillämpningar när man vill estimera modeller i realtid. T.ex. kan RMK användas för att finna modeller på hur framtida elförbrukning i Malmö (eller någon annan staThis thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor. The exact statistical properties for the RLS-estimator with forgetting factor ar
Popular Abstract in Swedish I stormaktstidens Sverige utgavs en fornsaga där den mytiske svenske kungen Vilkinus ligger med havsfrun. Under denna tid kunde vanliga människor som påstod sig ha sådana förbindelser dock råka illa ut. År 1630 förhördes pigan Anna Larsdotter, som misstänktes ha fött näckens monstruösa avkomma. ”Trollkarlen” Peder Jönsson avrättades tio år senare för könsumgänge och pakThis dissertation examines conceptions of erotic nature spirits and their association with demonic sexuality in 17th and 18th century Sweden. Its purpose is to reconstruct the various cultural and symbolic meanings which such notions had for the society of the day. Cultural history and the analytical concepts culture(s), liminality and figures of thought provide the general framework of the study.
Public service organizations rely on IT systems to fulfill their missions. IT incidents are more and more frequent and the impacts of IT incidents on the organizations are getting more severe. There is a strong need to manage risks on service related IT systems in public service organizations. Risk management process practiced in software development companies cannot be used in public service orga
