The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

The purpose of this thesis is to investigate if there exists a superiority between developed and developing countries, which then in turn effects the negative consequences, for the local inhabitants of Thailand, that follow from mass tourism.To be able to answer the questions that we have selected for this thesis, we chose to perform open interviews with six respondents which were all involved in the tourism industry in Thailand. Four of the interviews were carried out on location in Thailand. In order to deepen our understanding of the selected questions even further literary studies have been made as well. The theories we have chosen concern the topics of imperialism and figurations.Our empirical material gave significant results. It showed that there is indeed an imbalance of power between the western world and Thailand.

The aim of the study was to examine prerequisites for the changes that are taking place within working with Intimate Partner Violence in Va?stra Hisingen (a municipal district in Gothenburg, Sweden). My research questions concerned incentives for the new features, their practical consequences and prerequisites for implementation. The study has been performed by three focus group interviews with different parts of the organization represented. The work material has then been analyzed using Implementation Theory, Human Service Organization Theory and theories on breaking up.

In today´s labour market, men and women are segregated, both vertically and horizontally. Exceptions to the rule of gender segregation are few. There is, however, one managerial group where women and men are equal in numbers: school principals. In a short period of time, the distribution in terms of sex among principals in Sweden has changed dramatically. How does gender equality in numbers affect gender equality in a qualitative sense? That is the focus of this thesis.

I Sverige är det fortfarande en ojämn fördelning av uttaget av föräldradagar hos nyblivna föräldrar där mammorna tar ut den största delen.  Syfte:. Att undersöka hur föräldrar resonerar kring föräldraledighet, hur de väljer att fördela dagarna, vilka är anledningen till det och vad skulle få dem att resonera annorlunda. Metod: En explorativ studie med kvalitativ ansats. 12 semi-strukturerade intervjuer genomfördes med sex föräldrapar i åldern 25-42år som fått barn de senasta två åren, föräldrarna intervjuades enskilt.

Detta arbete har undersökt skillnaderna mellan den nuvarande skogsvårdslagen och den föregående. Undersökningen har bestått av två delar, där ena delen är en litteraturstudie av lagarna och den andra är en fältstudie av metoder för att mäta naturhänsynsförändring. Som komplement till fältstudien har en litteraturstudie av undersökningsparametranas naturvårdsnytta. Litteraturstudien av lagarna gick till på följande sätt, inledningen av båda lagarna och hänsynsparagraferna har lästs och jämförts. Fältstudie har gjorts efter metoder som har arbetats fram och sedan testats i fält.

In an attempt to prevent ground damage and to reduce harvesting costs, StoraEnso's districts Värmbodal and Fryken, selected a number of final felling areas where the base roads have been marked by planners in the districts. The parties involved in the experiment are mainly planners, harvester operators and forwarder operators. The purpose of this paper is to determine the findings of this trial and to find cost savings or lost revenue. This has been done with a sample of interviews from the involved parties who logged the chosen felling areas. Literature about the interview process has been used to facilitate data collection, interpretation and analysis of the material. If we look at profitability based on assumed income and expenditure, revenue per MWh would be 63 SEK.

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.

This paper discusses an osteological- and archeological analysis of a cairn from the Bronze Age on Gotland. The osteological material consists of both burnt and and unburnt bones from both human and animal. The objective of this paper is to shed light on the individuals who were buried in the cairn. It is also to generate information about continuity in its use and patterns of distribution of the bones and grave-goods in the cairn. The osteological analysis show that a minimum of five human individuals is present in the osteological material.

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.

The aim of this essay was to investigate the effects of adopting a site to the UNESCOs World Heritage List. Thefocus laid on the example of the Decorated Farmhouses of Hälsingland, which was the most recent Swedishadoption. With the question of impact of the World Heritage List in mind, the region of Hälsingland became themain focus. The study was made with particular focus on Gästgivars, a farm located in the municipality ofBollnäs, to which the theory of social life of things was applied. The result of the World Heritage was, in the caseof Gästgivars, an increase of the cultural value and social status.This case study has shown that the impact of the nomination has not been immense, but suggests that longtermeffects can show.

This paper aims to apply a specific architectural theory onto Lund City Library in order to achieve a better understanding of how the physical concept of the library is affecting our knowledge and our production of meaning; and furthermore how it suggests a certain form of usage. This paper discusses the ways in which architecture is affecting us when we use the library. The paper attempts to answer the following question: ? Which one of Koch?s spatial structures could apply to Lund City Library, and in which ways could this spatial structure be a producer of meaning? The specific architectonical theory used is developed by Daniel Koch in his paper Spatial Systems as Producers of Meaning: the Idea of Knowledge in Three Public Libraries. This theory is the method of the paper as well.

SammanfattningBakgrund: E- handeln av livsmedel visar på en ökande trend och svenskhandels rapport från 2012 visade en ökning på 40 % 2011. Detta medför nya affärsmöjligheter för livsmedelshandlarna och en av butikerna som implementerat e- handel är ICA- Rottne.Tidigare studier visar att kunderna efterfrågar korta leveranstider vilket kan vara svårt att möta. ICA- Rottne styr i nuläget sina leveranstider utifrån givna beställningsstopp och leveransintervaller. Syfte: Syftet med studien är att kartlägga processen från orderläggning till leverans. Syftet är dessutom att identifiera det maximala orderantalet ICA- Rottne kan färdigställa givet den nuvarande kapaciteten. Vidare är syftet att identifiera kapacitetsbrytpunkter med avseende på parametrarna antal orders och tid för beställningsstopp.

The aim of my bachelor?s thesis is to investigate, through a literature review, changes in the distribution of filamentous algae as well as the general species composition of macroalgae and diatoms in Swedish eelgrass meadows. I have also studied the possibility of tracking these algae and diatoms in eelgrass meadows using eDNA methodology. The focus has been on linking these changes to climate change factors such as eutrophication, temperature increase, and anthropogenic emissions, and how these affect the health of eelgrass meadows and their ecosystem services, such as a carbon sink and biodiversity support. The results show that filamentous algae have increased markedly in coverage in Swedish coastal areas between 1980 and 2021, especially in sheltered bays, indicating that altered environmental conditions favor these fast-growing species. Genetic tracking using eDNA demonstrated that there are functional primers for many species, particularly among brown algae and red algae, whereas green algae require more specific primers due to greater genetic variation.

Det går allt fortare. Nätjournalister befinner sig mitt i nyhetsflödet. De är bland de första individerna som får ta del av de nyheter som inkommer till en webbredaktion. Från att en nyhet inkommer till en webbredaktion till dess att den publiceras på nätet är en process som idag inte behöver ta mer än tio minuter. Under dessa tio minuter hinner en nätjournalist både att granska källan, kontakta eventuella vittnen, skriva nyheten och sedan publicera den.
