The critical effect of load representation in voltage stability studies is discussed in this paper. Under the same conditions in the system, the load representation will affect the location of the operating point in a P-V curve representation, leading the system closer to or further from the collapse point. The use of dynamic load models in voltage stability studies is motivated, especially in tho

Currently biofuels have strong political support, both in the EU and Sweden. The EU has, for example, set a target for the use of renewable fuels in the transportation sector stating that all EU member states should use 10% renewable fuels for transport by 2020. Fulfilling this ambition will lead to an enormous market for biofuels during the coming decade. To avoid increasing production of biofuel

Vilka faktorer skall man prioritera i samhällsplanering? Hur skall man analysera dem? Hur hänger olika faktorer samman? Hur skall man arbeta med sociala dimensioner som verktyg i planering? De prioriterade sociala dimensionerna i bostadsplanering har formulerats som allsidig demografisk struktur, rimliga omflyttningstal och attraktiva boendekvaliteter. I skriften analyseras planeringsstrategier kr

In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase. However, when biofuels are burned or

This chapter provides the first all-European overview of diverse aspects of living standards in a period when industrialisation and modernity began to show up in substantial improvements in general living conditions. Most obvious is this seen in the increase of life expectancy. A substantial contribution came from the decline in infant mortality which occurred almost simultaneously over large part

Popular Abstract in Undetermined http://lup.lub.lu.se/record/4331039/file/4333215.pdfThis dissertation deals with the electron-photon interplay in hybrid circuit QED structures. The aim is to provide a framework in which this interplay can be understood and to predict experimentally measurable transport effects. In addition an application of this interplay is proposed. The thesis is based on four paper listed below: Article I comprises an investigation of the transport-induced p

The purpose of this thesis is to contribute to understanding of the effect of organizational context on supply chain integration. One result is a context- based model that can provide support for practitioners regarding what level of integration to establish with suppliers and customers. Given the notion that most organizations are dependent on other organizations, it leads to a need for not only

The evaluation of the effectiveness of safety installations (such as emergency exits, lighting, etc.) is a key factor to improve the evacuation performance of buildings or transportation systems. In fact, even though an installation is designed to achieve a given design goal, it could happen it does not perform as intended. According to the Theory of Affordances, this could be interpreted in relat
