Wine is an important cultural crop and is grown in vineyards that sometimes claim to have a unique "terroir" - a specific taste and character based on their physical attributes and location. Regulations and previously published work are not easily available, into how to measure and assess this terroir. It is important for countries such as Sweden to have a terroir assessment system, whic
Purpose – While e-commerce marketplaces have changed the way SMEs operate across borders, literature connecting digital platforms with the internationalisation of firms is scarce. Although the Uppsala Model and the Born Global concept acknowledge the influence of digital technologies, they do not capture the phenomenon of e-commerce marketplaces as a new mode of entry. In light of the new opportun
In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr
Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va
In the last decades, scholars, managers and consultants have shown increased interest in identifying the characteristics of high-performance organizations. Searching for ways to improve organizational performance and respond to a growing demand for quality products and services in a rapidly changing environment, this subject is of special interest of managers in both public and private organizatio
Dialysis is a life-sustaining treatment for many people around the world. In or- der to meet the high demands on the dialysis machines, replaceable parts must be exchanged in proper time. Condition based maintenance (CBM) bases its service decisions on the actual health status of the component. The goal of this master’s thesis was to develop an algorithm based on machine learning, constituting the
This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. for banded Toeplitz matrices. The approach is geometric
The studied intrusion, the Hakefjorden Complex on Älgön is a norite-anorthosite complex situated in the archipelago on the west coast of Sweden. The origin of the intrusion will be deduce through in situ Sr-isotope analysis by MC-ICP-MS (multiple collector- inductively coupled plasma- mass spectrometry) on plagioclase, together with petrographic description and chemical analysis. The examined plag
Abstract On May 18th in Abu Dhabi, UAE, IRENA released a report declaring that Djibouti can meet 100% of energy demand through renewable energy sources by 2020. Today, 55% of the population lives without access to electricity, 60% is unemployed, and the country depends greatly on imports of energy sources, inter alia fossil fuels and electrical power, which contribute to the continued rising leve
The purpose of this essay is to examine how the Shoah affects Israeli society today and deals with the construction of identity and collective memory of the Post-Shoah generations in Israel. The study analyzes three Israeli documentary films through the theory of Marianne Hirsch’s “postmemory”. These films are The Flat (2011), Six Million and One (2011), and Defamation (2009). The essay cast its l
Increasingly popular, distance education has been researched from many angles, but studies done from a cultural analytic perspective are rare. Most studies up to this point have focused on the pedagogical perspective. This thesis aims to investigate challenges faced by different stakeholders in distance education, including online course promoters, teachers, and students, from a cultural analytic
An engineering approach to the evaluation of the TCP as a narrowband bearer for short messages in the low latency train-trackside communication scenario is described in this report. The project was developed in cooperation with Bombardier Transportation Sweden AB as a part of the “ETCS over GPRS” venture. With the increase of the demands from the railway industry, the currently used circuit-switc
A project at ABB CRC in Västerås aims at investigating the use of an MPC algorithm as a control module in 800xA. For users to interact with such a controller, faceplates need to be designed. This report describes the process, and results of designing such faceplates using among other the ABB Graphics Builder application. The challenge with the design work was mainly to create new and unique compon
For variable-frequency drives, the most common way to apply the desired power to an electrical motor is using PWM modulated signals. Due to high-frequency components, those signals give rise to reflections in the motor cables, radiated noise around the cables and acoustic noise in the motor. In order to avoid those problems, NFO Drives AB develops and produces an alternative to PWM modulation call
The debt equity bias refers to the discrimination between debt and equity finance. This discrimination is problematic since it distorts companies’ decisions and increases systemic risk. The European Commission has recommended Sweden to eliminate or reduce the bias and the Swedish Ministry of Finance has gathered a committee to investigate possible solutions. Sørensen (2010) suggested that Sweden w
Increasing demand for lower fuel consumption increases the importance of a higher total energy efficiency in trucks. Since the efficiency of a modern diesel engine is in the range of 40 %, large amounts of waste heat are produced. Recovering this energy can be done with thermoelectric generators. However, these generators’ open load voltage and internal resistance are temperature dependant, which
If adequately adapted, different sources of Lock-in provide new opportunities for companies on mature markets. Neglecting the importance of creating Lock-in in win-win situations could possibly make them victims of their external environment.
