The natural elements are used as a driving force for positive urban life in Akureyri, Iceland with the snow accumulation as a leader to unite the town in a physical and social way. The elements of snow buildup in the urban environment are used to find ways to give the town added value in the form of recreational opportunities and commuting routes. Additionally using a system of snow storage to min
This study aims to examine how the sensitivity for macroeconomic announcements surprises changes for the exchange rate in terms of a crisis. Previous research has been biased for U.S announcements and their relation towards emerging market, which has shown that U.S announcements affect more than the domestic. It also suggests that business cycle and uncertainty affect and increase the reaction for
The purpose of this study has been to investigate the experience of being a child challenging the food culture one was born into by going vegetarian. Five grown up informants who made a conscious and deliberate choice to abstain from meat during childhood have had the opportunity to tell their stories through a semi-structured interview. The interviews were analyzed thematically by means of Interp
Business Rules Engines are systems created to deliver relevant business information to applications and business processes. Given that rule engines are meant to be heavily queried, efficient rule search is essential. However, since the advent of Big Data, it has become increasingly difficult to maintain the rule engine performance - more data often leads to more rules. In this thesis we prototype
Acoustic trapping is a novel technology that allows for microfluidic sample preparation and pretreatment. The aim of this text is to give the reader a general insight in microfluidics with a focus on acoustic trapping. One of the next steps in the development of acoustic trapping is to promote commercialization of the technology which requires that similar devices can be manufactured reproducibly.
In high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. The model was fitted to the existing transverse momentum spectra (pT) for pions, kaons and p
The turbo code used in the 3GPP Long Term Evolution(LTE) standard have been chosen specifically to simplify parallel turbo decoding and thus achieving higher throughputs. The higher data rates however leads to an increased computational complexity and thus a higher power and energy consumption of the decoder. This report presents a turbo decoder for the LTE standard with a stopping crite- ria aime
One of the most pressing present day health concern is the constantly growing increase of diabetes and the metabolic syndrome. In fact the WHO estimates that as much as 300 million individuals could suffer from diabetes by 2025. While genetic factors do contribute to these issues the more common cause is modern day environmental factors like diets rich in fat or highly processed food, low levels o
Sammanfattning Detta arbete har delats in i två delar. Den första delen handlar om olika energilagringstekniker. Den andra delen handlar om att lagra egenproducerad elenergi i ett flerbostadshus. Syftet med första delen har varit att samla information om olika energilagringstekniker i en kunskapssammanställning genom att studera dess funktion, aktuella status och framtidsutsikter. Den andra delen Abstract This master thesis is divided into two parts. The first part deals with a general study of different energy storage systems. The second part deals with the possibility to store own-produced electricity from solar panels in a multifamily residential area. The purpose of the first part was to collect information about different energy storage systems in a general study, and examine their di
The relationship between macroeconomic variables and the stock market index has been studied by a large number of academics and practitioners over the last two decades. However,even though the stock market in China has been in rapid development, the similar studies concerning China remain relatively insufficient. This study examines the relationship between the China’s stock market and a set of ma
Today world’s cities are in a state of flux exhibiting complex dynamics and at the core of sustainability challenges including climate change and urbanization. At the same time cities have been acknowledged as agents of change when it comes to addressing these challenges. The urgency to address these problems has triggered cities to find smarter and innovative ways to deal with these challenges. C
Världen, och framförallt Europa, står idag inför stora påfrestningar med en flyktingström vars storlek enbart kan liknas med den under andra världskriget. Denna uppsats syftar till att svara på frågor kring flyktinginvandringens påverkan på den ekonomiska tillväxten på lång sikt. För att besvara frågeställningen görs en teoretisk analys genom att utvidga en tidigare utvidgad modell där effekterna
Denna rapport syftar till att studera regnbäddar och dess funktion vid rening av dagvatten samt vilka olika filter som kan användas. EU:s vattendirektiv från 2000 studeras tillsammas med hur kommuner arbetar med detta idag. En regnbädd definieras som ”en vegetationsbeklädd markbädd med fördröjningszon för infil- trering och behandling av dagvatten” och är en del av en öppen dagvattenhantering, d.v
The pipelined ADC is a popular Nyquist-rate data converter due to its attractive feature of maintaining high accuracy at high conversion rate with low complexity and power consumption. The rapid growth of its application such as mobile system, digital video and high speed data acquisition is driving the pipelined ADC design towards higher speed, higher precision with lower supply voltage and power
This study has investigated the possibilities of coating additive manufactured titanium dental prosthesis structures. Different coating alternatives were evaluated with the regards of esthetics, function and implementation possibilities. The coatings were applied on test samples and the adhesion between the printed titanium structures and the coating as well as to resin veneering applied on top wa
The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st
Bredäng, a housing area in southwest Stockholm, was built between 1963 and 1965 as part of The Million Program, a Swedish government program to fix the housing shortage in the country. Bredäng is characterized by its green and blue qualities, but also by its many parking lots, poor public spaces, monotone architecture and storm water issues. Today, the housing shortage is once again an issue, esp
