Hälsofarliga organiska och oorganiska ämnen blir allt vanligare förekommande i stora städer och på vissa platser i världen har luften varit så förorenad att det inte gått att vistas utomhus på grund av hälsorisken. Utsläpp av oorganiska ämnen som kvävemonoxid och kvävedioxid (NO och NO2) leder i städer med stora luftföroreningsutsläpp, i vissa fall, till lokal bildning av marknära ozon. Marknära o
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
Examensarbetet syftar till att jämföra olika insamlingssystem för matavfall från flerfamiljshus. För att uppnå Sveriges miljömål finns etappmål som anger att minst 50 % av matavfallet ska källsorteras och behandlas biologiskt för att ta tillvara på energi och/eller näring till senast år 2018. Detta innebär att antalet hushåll med tillgång till separat sortering av matavfall måste öka. Det vanligaTo facilitate the fulfilment of Sweden’s environmental objectives, there are interim targets regarding e.g. food waste. For instance: at least 50 % of food waste should be source separated and biologically treated to make use of energy and/or nutrients, by 2018 the latest. To achieve this, the number of households with access to separate collection of food waste must increase. The aim of this mas
In the pursuit of a system capable of measuring pain signals in humans we propose a method to differentiate those signals related to pain from those which are not. We performed a time-frequency analysis using the Gabor transform to have complete information about the spectrum and its behaviour through the time to study the main differences over the evoked potentials provoked by both nociceptive an
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
When viewing moving objects in videos the movement of the eyes is called smooth pursuit. For evaluating the relationship of eye tracking data to the moving objects, the objects in the videos need to be detected and tracked. In the first part of this thesis, a method for detecting and tracking of moving objects in videos is developed. The method mainly consists of a modified version of the Gaussian
A short introduction to optimal control problems is presented. For these problems the calculation of sensitivity matrices with the method of adjoint equation is shown. The adjoint equations are derived with the corresponding initial values. At the end two examples are calculated.
This study has focused on challenges encountered when setting up a weather-network for agricultural purposes (e.g. linking temperature to the suitability of crops and pest incidence) with only low-cost sensors and materials. The study included a set of experiments in a meteorological station and a one-month period of observations in a large coffee plantation with a complex terrain in Costa Rica. T
Like many other lakes, Lake Ringsjön in Sweden has a long history of eutrophication problems. Eutrophication of lakes is mainly due to surplus of phosphorus. Most phosphorus reaches Lake Ringsjön from adjacent watercourses. In order to initiate action plans to reduce phosphorus concentrations in the lake, it is of great importance to know which watercourses have high phosphorus concentrations. Pho
Sammanfattning En arbetsgivare är enligt lag förbjuden att diskriminera en arbetstagare, praktikant eller arbetssökande med en funktionsnedsättning. Det föreligger en skyldighet för arbetsgivaren att vidta de stöd- och anpassningsåtgärder som anses nödvändiga och rimliga för att de individer med funktionsnedsättning ska hamna i en jämförbar situation med individer utan funktionsnedsättning. Med b
Religionsfrihet i arbetslivet är ett aktuellt ämne som ständigt utvecklas och möter nya utmaningar. En dagsaktuell del av religionsfriheten är möjligheten till samvetsfrihet för barnmorskor, vilket innebär att en barnmorska kan vägra utföra aborter med hänvisning till sin religion. Syftet med denna uppsats är att undersöka möjligheten till samvetsfrihet i Sverige. För att undersöka detta har jag aFreedom of religion at the workplace is a current topic that is constantly evolving and facing new challenges. An up-to-date part of the freedom of religion is the possibility of freedom of conscience for midwives, meaning that a midwife can refuse to perform abortions, according to their religion. The purpose of this essay is to examine the possibilities of freedom of conscience in Sweden. To exa
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
Syfte: Syftet med uppsatsen är att undersöka om en signifikant skillnad i riskaversion råder mellan de två populationerna, där den ena arbetar för en fast lön och den andra för en provisionsbaserad lön. Även de oberoende variablerna som antas ligga till grund för en individs riskaversion kommer att undersökas. Metod: En tvärsnittsstudie genomfördes av två populationer med hjälp av en internetbasePurpose: The purpose of this thesis is to investigate whether there is a significant difference in risk aversion between the two populations, where one is working for a fixed salary, and the other for a commission-based salary. Independent variables that may represent the individual's risk aversion will also be examined. Methodology: A cross-sectional study of two populations was carried out
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
Much of the equipment used in Snoezelen environments today is not interactive, and the equipment that is interactive can be hard for the user to access. By having interactive equipment in Snoezelen environments the user gets to experience and hopefully better understand the concept of cause and effect. The purpose of this master thesis has been to develop an interactive interface that can appeal
Sony Mobile has a quite large internal user group with the purpose of investigating the usability of their mobile devices. The Telephony Domain was using among other techniques usability testing to evaluate the usability of their products. The performed conventional usability testing has its limitations e.g. the controlled test environment cannot fully represent real life setting and it’s very exp
A common approach to treat respiratory diseases is with adhesive powder mixtures. These are dispersed into an aerosol upon inhalation. It has been found that the performance of such mixtures can be improved by adding fine particle lactose, but exactly why is yet to be established. Several theories have been proposed by previous studies, but the fundamental mechanism is still unknown. This study w
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
