Samverkansanalys mellan påle och kohesionsjord. Studie av FE-programmet PLAXIS 3D FOUNDATION
On a request from the water sewage plant Gryaab in Gothenburg a Power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Timmerkvalitet hos björk i blandskog med gran
Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).
Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kärnkraftsdebatten
Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

Sjuksköterskors och läkares delaktighet i kvalitetsutveckling : En fallstudie vid Karlskoga lasarett
The purpose of this master's degree thesis was to develop an understanding of how hospital management, in the case studied, worked to achieve changes in an organization influenced by differing professional cultures. To gain insight into the conditions that may have contributed to nurses and physicians developing appropriate attitudes and behaviours, which may have affected the organization's ability to achieve the Swedish Quality Award 2012. A qualitative single case study was conducted at Karlskoga Hospital, with focus groups as well as individual depth interviews. The results of the case study showed the following conditions provided nurses and physicians the potential to develop appropriate attitudes and behaviours, which may have influenced the hospitals ability to achieve the Swedish Quality Award: Responsibility and influence over the development processes.Participation in management teams and quality development groups as well as individual fields of responsibility.Training programs that have given insights and skills in quality management related to clinical practice.Nurses and physicians as key individuals gave legitimacy to development process, and served as management advisors.Collaboration between all kind of employees and responsibilities.Committed management. .

Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection
of the energy consumption of their clients. Often computerized remote meter
readers are put in practice in order to register the energy consumption of
large companies. The majority of household clients, however, are read off by
the assistance of manual methods.
Household power consumption is read off once a year. As a result, these clients
are not debited for their actual consumption; their invoices during the year
are the result of estimations. At times when the electricity supply system is
highly loaded, electricity is more expensive.

Exploatering, kommodifiering och megaf?retag i popul?rmedia: En kvalitativ narrativanalys av datorspelet Cyberpunk 2077
This thesis aims to research how megacorporations are depicted in popular media by analyzing the video game Cyberpunk 2077. In this assignment I focus on how the narrative of said game discusses economic globalization, megacorporations specifically which is accomplished using a set of theories such as: exploitation, commodification and capitalist realism. The analysis is constituted using a modified version of narrative analysis in order to better suit my research field as well as presenting a clear and concise structure a reader can follow. This study concludes that Cyberpunk 2077 constructs a dystopian world with the megacorporations holding the political power where the majority is constantly oppressed by the 1% in power. Things that we find human are questioned and diminished in order to increase the profits of those in power which tends to be the megacorporations.
