This thesis consists of four self-contained papers in applied microeconomics. The first paper asks how a neighbors purchase of a specific good affects a households likelihood of purchase. I use an image classification algorithm to process a large set of aerial photos in order to infer household ownership of a visible durable good, specifically a trampoline. To estimate the neighborhood effect, I u
Bidraget behandlar hur etnografi kan bedrivas i en mer kreativ riktning och vikten av att bryta mot inarbetade procedurer och normer inom forskning.
Background: Nausea and vomiting in pregnancy (NVP) affects 50–80% of pregnant women and is correlated to the level of human chorionic gonadotropin (hCG). Hyperemesis gravidarum (HG) is a severe condition, with an incidence of 0.2–1.5%, characterized by consistent nausea, vomiting, weight loss and dehydration continuing after the second trimester. Aim: The aim of this systematic review was to inves
The European Synchrotron Radiation Facility (ESRF), a leading facility in synchrotron science, plays a crucial role in supporting both the local and the international scientific community by providing advanced instrumentation for their research. However, our understanding of the actual reach of the facility and its spatial dynamics remains limited. Thus, a methodology is proposed where author affi
In industries like high-tech and automotive, increasingly more of the product value delivered to the customer is based on a combination of hardware (HW) and software (SW), where SW handles much of the differentiation of capacity and features. The “logistics process” of SW, especially when it merges with HW along the process, has so far been little studied but a problem noticed is the difficulties
This paper describes the RTD project FRR (Friendly Rest Room) which is partly funded by the EU in the Quality of Life programme. The objective of the FRR project is (a) to create prototypes of more user friendly rest rooms for old persons and for persons
In this paper, start-up of a plate reactor is considered. Dynamic optimization is used to obtain start-up trajectories, and a feedback control structure for on-line control. The problem is challenging, since the process model is large and highly non-linear. In addition, the plant is subject to uncertainty. Special attention is given to the problem of formulating an optimal control problem based on
The frame story
takes place in a dystopian Europe, possibly some kind of European Union around 2050 – in a state of conflicts and decay. The protagonists are a retired general, Piscator (cf. Fisher King) and a former journalist, Perle Vaus (cf. Perlesvaus/Perceval/Parsifal). She lost her home because of a new genderrelated law and stays homeless with others, covered by the Saxon bridge.

When developing commercial software products it is crucial to select the right requirements for the right release and to have a short mean-time-to-market (MTTM) in order to be competitive. We report on a simulation of a model of market-driven requirements engineering processes with requirements selection quality as a key aspect. The simulator is built using an open source simulation framework and
Carsim is a program that automatically converts narratives into 3D scenes. Carsim considers authentic texts describing road accidents, generally collected from web sites of Swedish newspapers or transcribed from hand-written accounts by victims of accidents. One of the program’s key features is that it animates the generated scene to visualize events. To create a consistent animation, Carsim extra
