Bostadsområdet Husensjö i Helsingborgs stad är ett av flera områden som troligtvis kommer att genomgå en förtätning till följd av befolkningsökningen i staden. Området har ett utsatt läge då det ligger i en naturlig lågpunkt och därmed tar emot stora mängder avrinning från det kringliggande avrinningsområdet samtidigt som vattnet inte kan ledas ut på annat sätt än via ledningsnätet. I och med att

The number of devices connected to the Internet is rapidly increasing. Especially the number of Internet of Things devices. These devices contain software which, like any other software, needs to be updated. With the great amount of devices to update, this calls for a manageable updating solution which does not depend on user interaction. In this thesis we present a solution to dynamically update

This thesis extends previous work on improvisation in operational environments by asking if the tendency to improvise among maintenance technicians, working on a remote location in a centralized organization, is influenced by circumstantial factors. The factors of interest in this study are the accessibility of help from the centralized organization and the perceived degree of centralization. Thi

All over the arctic and sub-arctic region global warming is affecting permafrost. When permafrost thaws, organic material becomes available for decomposition, hence an increase of greenhouse gas emissions to the atmosphere. In the northernmost of Sweden, on a mire close to Abisko, a snow manipulation project is ongoing. The experiment is trying to mimic predictions of future conditions and advance

This publication is a summary of the work with my degree project in architecture and a description of the process during the length of the project. The main program is the design of a nature visitors center in a nature-reserve. The design process is influenced by parametric design to solve specific design goals, light studies and the experience of volume.

This thesis investigates how multi-actor dependencies affect the ability to assess capability. It is also investigating if the accuracy of capability assessments for tasks where multi-actor dependencies are present, depends on if capability is assessed individually or with all participating actors. Two multi-actor dependency models were considered representative for all cases. Dependency I represe

Flyttningsmönster hos två populationer av större strandpipare beskrivet med hjälp av ljusloggrar Fågelflyttning är ett resultat av naturlig selektion och är anpassad till alla delar av en fågels liv, så som miljön den häckar i, dess byte av fjädrar och konkurrens med artfränder oh andra. Eftersom fåglar finns i nästan alla miljöer är variationen på olika sätt att flytta stor. Ibland uppstår tydliLeap-frog migration, i.e. when a northerly breeding population/species migrates further south compare to southerly breeding population/species, is a common migration pattern in birds. However, it is still unknown which factors facilitate the evolution of such a migration pattern pattern. A textbook example of a species exhibiting leap-frog migration is the Common Ringed Plover Charadrius hiaticula

Kan vi förutsäga skånska våtmarkers igenväxningshastighet? Det kan vara svårt att underhålla våtmarker på regional nivå, inte minst eftersom det är såväl kostsamt som tidskrävande att ständigt hålla uppsikt över de våtmarker man ansvarar för. Det vore därför önskvärt att se om man kunde ge en uppskattning på hur lång tid det i snitt tar för en våtmark att växa igen till den grad att den behöver rScanian wetlands were extensively drained in the late 19th and early 20th century, with as little as 10% of historical wetlands remaining today. However, due to an increased understanding of the many important functions served by wetlands in the agricultural landscape, there’s now a strong incentive to restore these systems. In this study, 83 wetlands created as part of Kävlingeåprojektet were vis

As a consequence of increasing land-use intensity and changes in farming practices, many species of pollinators have been shown to decline. These declines have led to concerns about crop pollination services performed by wild pollinators. The aim of this study was to investigate whether farming practice (organic and conventional), and increasing percentage of semi-natural grassland in the surround

Urbaniseringen innebär att det blir mer och mer hårdgjorda ytor i städer, vilket ökar belastningen på dagvattennätet. Vidare så innebär klimatförändringarna ytterligare utmaningar då nederbörden i Sverige antas öka. För att hantera detta föreslås hållbara dagvattenlösningar varav gröna tak kan vara en del. Detta skapar ett behov att på ett enkelt sätt modellera avrinningen från gröna tak. I detta The increasing urbanization means there are more and more impermeable surfaces in cities. This is straining the capacity of the stormwater network. Furthermore, climate change is assumed to bring about more precipitation in Sweden in the future. In order to deal with these challenges a sustainable approach to stormwater management is needed. Green roofs can be one part of the solution. This create

This thesis explores the communication between interconnected System-on-Chips that process images. It explores the difficulties faced when combining two heterogeneous multiprocessors to act as a single unit. It also examines the performance gain of the resulting system. The thesis shows that not only does the resulting system decrease the bandwidth usage on the individual System-on-Chips, but it

Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo

Here we present a solution for debugging compilers that use abstract-syntax trees as their internal structure. The solution focuses on capturing one specific state of the compilation process, and should not be confused with the more known step-by-step debugging. The goal is to visualize the current state of the abstract-syntax tree and present its data to the user in an intuitive and interactive w

The purpose of the thesis is to examine the evidence for druids and their actions in classical texts and archaeological finds. Initially the materiality and description of druids in the classical sources will be analysed. It will be followed by an analysis of a selection of archaeological finds that researchers have connected to druids. Finally, the archaeological material will be discussed in ord

Med växande miljöhot så blir det allt mer viktigt att vi alla minimerar vår miljöpåverkan. För att förenkla detta har vi utvecklat en app som kan räkna ut miljöpåverkan genom en användares bankutdrag.Many people want to know the socio-ecological impact of the goods they purchase. In this thesis, we describe a system that computes the socio-ecological impact of those goods by analyzing uncategorized financial transactions. The computation is made possible by extending a system that can computate socio-ecological impact from categorized transactions. The extension further includes visualizations

The aim of this study is to explore narratives on violence in lesbian relationships. The study seeks to explore how stories and the act of storytelling can be used as a means to investigate a topic that has been discounted by focusing on the conditions and limitations for speaking. The study consists of both a personal narrative about being in a relationship with violence and community-based persp

Ponds are important aquatic ecosystems despite their small size. They provide the same ecosystem services and benefits than bigger waterbodies. Here I compared 18 ponds from southern Sweden to see what effect fish presence has. To establish this, the macroinvertebrates community was studied. The results show that there is a possible effect of fish size in the abundance and diversity of this commun

The paper investigates data on purchasing price of wheat from Swedish grain buyer Lantmännen and MATIF future contracts on milling wheat in an attempt to replicate the conditions for a Swedish farmer trying to manage his risk on wheat by trading future contracts on the MATIF exchange. Two static linear regressions and four dynamic GARCH models are employed on a sample of 1679 daily returns and 339

This study examines the pro-trade effects of immigration on Swedish exports. Beginning in the theory that immigrants through their unique set of networks and knowledge can facilitate international trade and bridge informational barriers to trade, this study will estimate the immigration effect on exports for Sweden. Unlike studies in similar settings, this paper applies a Pseudo poisson maximum li
