This thesis explores methods to find features that affect the start time of mobile apps. To help app developers improve performance over patch cycles, we implement an alarm pipeline in Apache Spark and tested it. This implementation is able to detect notable changes in the start time distribution and alert the developer. Spark is a scalable cluster computing framework, that proved well suited for

Vattenkraften står för hälften av vårt elbehov i Sverige idag. Merparten av vattenkraftverken är gjutna i betong och som många andra betongkonstruktioner så drabbas betongen av sprickbildning av olika orsaker. För vattenkraften är genomgående sprickor ett problem då dessa skapar läckage. För att förhindra dessa sprickor har en ny metod börjat undersökas där bakterier som kan avsätta kalciumkarbonHalf of the electricity needed in Sweden today is produced by hydro power. Most structure parts in hydro power stations are made of concrete and as many of other concrete structures they contain cracks. Cracking through dams are a big problem for hydro power since they create leakage. To prevent cracking a new method is under investigation. It consists of incorporating calcium carbonate precipita

As volumes of e-waste (WEEE) are increasing worldwide, the environmental and health impacts caused by this waste stream are leading to rising concern over how it is managed and disposed of. In the European Union this has been addressed by the WEEE Directive, a policy requiring all Member States to have a system for managing e-waste. The revised policy (Directive 2012/19/EU) sets increasingly ambit

In 2015, The Swedish central bank; the Riksbank, decided to lower the repo rate to -0,1 percent. The idea was to stimulate inflation in order to reach the target inflation of 2% according to CPI. The decision was and is controversial. Even if the inflation based on CPI is very low, the inflation on asset prices especially in the housing market is very high. Meanwhile, the household debt is increa

The aim of this study was to examine how unaccompanied asylum seeking children perceived their time within the social service system in Sweden, and in what way this time period in their life has affected them today. In researching this, its specific aim was to explore if there was any specific way of meeting these children which had a positive effect on their future in their new country. The stud

Arbetar samhällsviktiga verksamheter gemensamt för att hantera samhällets sårbarheter? När en händelse såsom då en storm sker, kan de allra flesta se hur sårbart samhället är och hur lätt ett problem hos en verksamhet snabbt sprider sig till andra verksamheter i samhället. Hur arbetar aktörer gemensamt för att hantera detta? Vi är många som har vaknat upp en morgon och sett att vägarna ligger vThe objective of this thesis is to provide answers to how a method can be designed to gain better knowledge of how collaboration looks between different critical societal activities in a preparing and preventive stage related to the management of transboundary risks. The designed method consists of two parts; a technique for data acquisition, and a method for data analysis. In order to evaluate th

Gröna tak – en samhällsekonomiskt lönsam lösning för att bibehålla viktiga ekosystemtjänster i städer? Den växande urbaniseringen är en global trend och idag bor åtminstone 54 procent av världens befolkning i städer. År 2070 förväntas 70 procent av världens befolkning bo i städer och Sverige är idag det land med näst högst urbaniseringstakt. Precis som i flera andra länder används i Sverige förtäCity densification in Sweden has decreased the amount of green areas in Swedish cities. This undermines the existing ecosystem services that could for instance provide climate change mitigation and adaption. Green roofs are considered to be a product that can strengthen or substitute the urban ecosystem services produced by natural vegetation. This paper investigates whether retrofitting green roo

Den europeiska stålindustrin står för en betydande del av EUs CO2-utsläpp, men har samtidigt begränsade möjligheter att minska utsläppen från befintliga produktionsmetoder. Det krävs därför nya, banbrytande processinnovationer för att åstadkomma verkligt stora utsläppsminskningar. Denna rapport ger en översiktlig beskrivning av den europeiska stålindustrin teknologiska innovationssystem, belyst geThe EU steel industry is a major contributor to human-induced CO2 emissions and has limited possibilities to improve incumbent production methods further. The industry is therefore strongly dependent on new breakthrough decarbonisation technologies in order to further mitigate emissions. This report provides an overview of the EU steel industry’s technological innovation system, through a new mapp

Lund Municipality, just like many other municipalities, has recurring problems with rutting at their bus stops. There is a notable problem in Lund though and the rutting occurs regardless of whether the stops are placed at high, medium or low-volume roads. In this thesis, eleven of the most vulnerable coatings in Lund Municipality were investigated. This thesis is written in collaboration with roa

The Resource-Based View (RBV) är teorin som beskriver processer där företag har och utvecklar konkurrensfördelar. I RBV identifierar Dierickx & Cool (1989) att en resurs imiterbarhet villkoras av dess ackumuleringsprocess. Författarna nämner därefter olika förhållanden som försvårar imiterbarheten i en resurs. Två av dessa är Asset Mass Efficiencies och Interconnectedness of Asset Stocks, i deThe Resource-Based View describes processes in which business corporations develop competitive advantages. Dierickx & Cool (1989) identifies the imitability in an asset stock as dependent of the process in which it is accumulated. The authors highlight different situations which aggravates the imitability in an asset stock. Two of these are Asset Mass Efficiencies and Interconnectedness of Ass

Due to unusually low precipitation during late autumn and winter of the year 2015/2016 the groundwater levels of south-eastern Sweden have reached the lowest levels ever recorded since measurements began in 1968. In the month of April in the year 2016 the Geological Survey of Sweden (SGU) made a public statement to the media announcing that unless substantial amounts of precipitation is added duri

This research is inspired by the concerns of deterioration of the environment by human activities. Small and medium-sized enterprises (SMEs) represent 90% of all businesses in the world. SMEs as organizational level members of societies are responsible for environmental sustainability as other society members for the damages of their business activities to the environment. The current study aims

Pavements on bus stops is a complex subject because of the different forces that occur. Cement Stabilized asphalt is therefore used on the bus stops and has been so for about 16 years in Malmö to combine the best qualities of cement and asphalt which is bearing capacity and flexibility. In 2014 a formula was developed to calculate the breakdown of the pavement of bus stops by two students at Lunds

This thesis examines the occupational mobility of a sample of immigrants who arrived in Sweden between 1971 and 1985. The data includes information on pre-immigration occupation and on up to four occupations in Sweden. The empirical analysis supports a U-shaped pattern of occupational mobility from home country to host country which is in line with the theory of imperfect transferability of skills
