The accurate and reliable detection of opening of doors and windows is vital for home security applications. This master thesis aims to present a way to achieve this using a low-cost and low-power ecompass, containing a MEMS accelerometer and a magnetometer. This has been achieved by attaching such a device to a door and collecting sensor data when opening and closing the door. Said data were then
Malaria är en av de tropiska sjukdomarna som utgör ett stort hälsoproblem i många delar av världen. Sjukdomen orsakas av en så kallad tropisk parasit av släkte Plasmodium och överförs till människor via mygghonan Anopheles. Den vanligaste och mest dödliga formen av sjukdomen orsakas av Plasmodium falciparum (Pf). Den förekommer i 104 länder där ca. 216 miljoner nya fall registreras årligen. Av desMalaria is one of the diseases that spread by insect vectors. The disease is carried to humans by female Anopheles mosquitoes. It is caused by the plasmodium types. The most prevalent and dangerous type of plasmodium is Plasmodium falciparum (Pf). The disease occurs in 104 countries and approximately 216 million new cases of malaria and around 655,000 deaths takes place every year. Many drugs have
Fisken i frysdisken Den ljuvliga doften av ört- och honungsmarinerade lax döljer en mycket mörkare sanning bakom fasaden som det hälsosamma och miljövänliga alternativet. I svenska hem äts det allt mer lax och importen från Norge ökar. Vi känner nog alla igen de fyra inplastade rektangulära rosa fiskbitarna som nu står färdiglagade på bordet. Laxens hälsosamma aspekt grundar sig i att den är eFarmed salmon is today commonly available in grocery stores where it is marketed as a healthy and environmentally friendly alternative to many other fish species. The fact that the diet of farmed salmon substantially consists of fishmeal is a fairly unknown fact. I performed a study which in its first part set out to identify the most negative environmental consequences of farming salmon. I show t
Poppar popcorn plötslig? För det mänskliga ögat verkar det som att popcorn poppar momentant. I det ena ögonblicket ligger det ett stenhårt majskorn i grytan; i nästa ögonblick flyger ett fluffigt popcorn i luften. Övergången från potentiell tandkrossare till aptitretare verkar vara omedelbar. Men kan det verkligen vara på det viset? Vår intuition och lite reflekterande eftertanke säger oss att pro
Improving teamwork has become a major safety goal for healthcare organizations. Audit tools currently available are useful, but they remain inadequate because they are reactive and fail to provide context for “the interaction between people and the operational context (i.e., organizational, regulatory and environmental factors) within which people discharge their operational duties” (Maurino, 2005
Att kunna göra tillförlitliga prognoser är varje läkares mål. Med hjälp av maskininlärning, framförallt neurala nätverk, har vi tagit fram modeller som presterar bättre än tidigare studier. Årligen drabbas hundratusentals människor världen över av ett hjärtstopp utanför sjukhuset (eng. OCHA). Tyvärr är chansen att man överlever endast mellan 5 till 10 procent. Om man överlever det initiala hjärtst
Genom att utnyttja vissa strukturer i den finansiella marknaden kan man skapa prognoser för finansiella instrument. Prognoserna man kan man utnyttja i in en algoritm som optimerar en portfölj av olika instrument. Resultatet är en portfölj som över mer i värde än själva instrumentet. Vi har all hört att man bör spara pengar inför pensionen. Många väljer att spara pengar genom att placera pengarna In this thesis model predictive control (MPC) is used to dynamically optimize a portfolio where the data is sampled every 5 minutes. Previous research has shown how MPC optimization applied to daily sampled financial data can generate a portfolio that exceeds the value of standard portfolio strategies such as Strategic asset allocation. MPC has been found to have a computational advantage when ret
The study aims to shed more light on the relationship between Internet penetration and labor productivity by analyzing the aggregate cross-country panel data available for a wide range of countries in the period of 2001-2015. An overview of hypothetical mechanisms behind the communication technologies’ impact on productivity is provided, while the Augmented Solow model is used as a theoretic frame
The memory is by far one of the brain’s most important and fundamental functions, but perhaps also one of the most unreliable. In order for information to be retained in memory, the brain performs, in a few milliseconds, an outstandingly complex process that is also very sensitive to external disturbances. With the information technology available today, it is easy to be distracted by redundant in
This study examines the connection between female representation in the political elite and the political participation of young women. Using theories regarding political participation in general and role model effects in particular, the hypothesis that an increase in the degree of female ministers and MPs leads to an increase in the degree of young women who become members of political parties in
The features of social media platforms not only enable the communication between citizens and political actors or institutions, in the form of comments, but also help in magnifying citizens’ voices and opinions and facilitating mass mobilization or political protests. The European Union institutions seem to understand the capacity of social media as a locus for citizen engagement, be it activism o
By increasing the amount of CO2 emissions to the atmosphere because of using fossil fuel and the limitation of non-renewable energy sources, solar photovoltaics technology has been growing steadily and is thought to play an important role in the realm of future energies. The objective of this thesis is to investigate the potential of the rooftops for installing PV system on a small scale of 30 mu
Mother tongue tuition (MTT) has been part of the Swedish educational system since 1977, with now almost 30 per cent of elementary school students eligible for the subject. With an increasingly globalized world, as well as expectations from the EU of all their member states’ citizens learning at least three languages, MTT could work as a means to meet the goal of a more linguistically knowledgeable
Cell death is an important field of biology that is linked to many other topics in medicine and biology. One of the methods to investigate cell death is through high content screening (HCS) which makes use of robotic microscopy. By this technology, cell death associated organelle membrane permeabilisation and the localisation of certain dyes can be visualised and elucidate a substantial amount of
Laundry as a household activity has been subject to (un)sustainable consumption studies. The majority of those studies are rooted in mainstream approaches to (un)sustainable consumption focusing on either changing individuals (e.g., their decisions, behaviors, habits) or system (e.g., infrastructure, technology). Moreover, the laundry has been predominantly studied as a washing activity. This rese
Tillgången till rent dricksvatten varierar mellan olika delar i världen. Till exempel är grundvat- ten en stor resurs i Sverige där det står för 50 % av dricksvattnet, både artificiellt och naturligt bildat. Den siffran är endast 6 % i Moçambique och med tanke på att 47 % av populationen i landet saknar rent dricksvatten kan artifici- ell grundvattenbildning vara ett bra alternativ. Det finns olikThe amount of clean drinking water varies across different parts of the world. For example is groundwa- ter a big resource in Sweden and stands for 50% of the drinking water, both artificially and naturally recharged. The corresponding fraction is only about 6% in Mozambique and considering that 47% of the population in Mozam- bique lacks clean drinking water artificial recharge might be a good op
Let μ be a positive measure supported on a planar domain Ω. We consider the behavior of the balayage measure ν:=Bal(μ,∂Ω) near a point z0∈∂Ω at which Ω has an outward-pointing cusp. Assuming that the order and coefficient of tangency of the cusp are d>0 and a>0, respectively, and that dμ(z)≍|z-z0|2b-2d2z as z→z0 for some b>0 (here d2z is the Lebesgue measure on C), we obtain the leading order term
According to the Swedish Red Cross, there are over 40 million people fleeing from war and conflict around the world. Some of these individuals are suffering from a disorder named PTSD (Post Traumatic Disorder Syndrome). This disorder is caused by previous experience incurred by war, conflict and violence. My intention with this study has been to increase the knowledge about refugees in Sweden suff
The effect from mechanical-biological pre-treatment (MBT) of wastes in Sweden and Germany has been studied. The organic matter and biological activities were studied and compared. Other parameters such as heavy metals and nutrients were examined and related to the organic matter. The effect of low water content on degradation was investigated and the relevant legislation in the two countries was s
This study aims at applying the livelihood strategy approach in understanding how women in a suburban area deal with the choices in economic activities in order to create their livelihood strategy. Using qualitative interviews of women in Nhu Quynh town (Van Lam district, Hung Yen province), a suburban area of Hanoi City, and the study explores livelihood strategies of women before and after 1997,
