This study was made to see too what extent Swedes uses consumptive resources such as berries and mushrooms, game meat and meat from fish in their household on a yearly basis. I have also looked into the difference between rural and urban areas in Sweden. Further aim was to determine what factors that correlates with the participation in berry and mushroom picking and the use of game and fish meat within the household. The study was conducted in form of a mail survey that was sent to randomly chosen persons in every municipality in the six northern most counties in Sweden and in the county of Stockholm. In addition a sample was sent to randomly chosen persons on a national level.The results showed there is a difference in use between rural and urban areas in Sweden in all 4 investigated consumptive resources.

Denna studie är utformad som en utvärdering och skiljer sig något från en ordinär uppsats. En väsentlig del i skillnaden är att teori delen upptar en större del i den ordinarie uppsatsskrivningen medan fokus kring en utvärdering mer inriktar sig på för vilket syfte utvärderingen görs, för vem och ur vilka perspektiv tolkningarna görs. I min studie har jag gjort en utvärdering kring ett samverkansprojekt mellan Försäkringskassan och Malmö stad där syftet med denna varit bland anat att se till hur projektet förmått att nå upp till sina mål och om projektet tillfört något ur ett kvalitativt eller effektivitets perspektiv. Det empiriska materialet inhämtades genom sju semistrukturerade intervjuer med personer inom tre olika kategorier; handläggare från Försäkringskassan, handläggare från Malmö stad samt deltagare. Materialet transkriberades och analyserades utifrån olika teman varefter uppgifterna ?triangulerades? i syfte att bekräfta resultat sedda från olika perspektiv.

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The purpose of this thesis is to examine how reading different media forms can lead to different experiences for the reader and how they choose which media form to read. Two questions are posed in the study. Question number one is: How does the media form influence the reading experience of the book and question number two is: What reasons can be seen behind the different choices of media forms?The study is based upon qualitative interviews with six readers using different media forms. Two different theories are used for analyzing the result.

Denna studie undersöker om det finns faktorer inom optikbranschen som, samt hur dessa faktorer i så fall, påverkar e-handeln av glasögon. Författarna har uppmärksammat en svag trend kring ehandel av optikprodukter. Då mycket fokus de senaste åren riktats mot kontaktlinser väljer författarna istället att grunda undersökningen på glasögon. Idag har få av de traditionella återförsäljarna e-handel och ännu färre erbjuder glasögon på internet. Det teoretiska ramverket baseras på den service-dominerande logiken som på senare år framkommit inom marknadsföringsforskningen.

This report consists of two parts, out of which the first deals with the planning and designing ofa small house in the Swedish city of Huddinge, using the weather conditions of the Swedish cityof Malmö. The house has to be in accordance with the Swedish building- and constructionregulations, as well as with the limitations in energy consumption given.The house itself has to consist of at least two bedrooms, and blueprints of the house, variousconstructional elements, ventilation, sanitation and electricity have to be drawn. Calculations ofthese aspects also have to be made, to ascertain that the different parts function as they should,and that the dimensions are sufficient.The second part is called ?Allergy free home?, and investigates how indoor climate affects us,and whether it has changed during the last few decades. It also makes an effort to see whetherthe increase of allergies and asthma is correlated with possible changes in indoor climate, andwhether technical solutions might help to handle or even decrease the issues arisen.

Sulfitlut, en biprodukt som erhölls från pappersmassaindustrin, blandades med ostvassla som är en biprodukt från osttillverkningsindustrin, för att odla fyra olika Zygomyceter i blandningen för produktion av proteinrikt biomassa.Arbetet fokuserades på den maximala produktionen av Zygomycetbiomassa från olika koncentrationer av biprodukterna sulfitlut och ostvassla i skakflaskor och de bästa förhållandena upprepades i en bioreaktor i bänkskala. Bästa odlingen för de olika Zygomycetstammarna vid 35 °C påvisade att vid 30%ig sulfitlut hade M. indicus och M1 producerade maximal koncentration (4,0 respektive 3,8 g/L) och utbyte (0,1 respektive 0,09 g/g) av biomassa efter 72 h. Maximala etanolproduktionen samt utbytet från dessa stammar var vid 38 h 12,4 g/L (0,31 g/g) respektive 13,4 g/L (0,30 g/g). Konsumerat socker för respektive etanolproduktion för dessa stammar var 41,2 g/L respektive 44,0 g/L.För odling i bioreaktor valdes M1 i ett medium med 50%ig sulfitlut med ostvassla, detta för att experimentera med mer användning av sulfitlut samt M1 som ursprungligen har isolerats från en indonesisk maträtt, tempe.

Biogas är en förnyelsebar energikälla som tillverkas genom att organiskt material som matavfall bryts ner av mikroorganismer under anaeroba (syrefria) förhållanden. Regeringen har satt upp mål för en högre matavfallsutsortering vilket leder till ökad mängd tillgängligt substrat till biogasproduktion.Matavfallet som samlas in börjar brytas ner under tiden det transporteras och lagras. Syftet med studien var att undersöka hur länge matavfall lagras, ta fram ett representativt recept på ett genomsnittligt matavfall i Sverige och utvärdera hur mycket metanpotential som försvinner från matavfall med avseende på lagringstid, insamlingssystem (papper- och plastpåse) och lagringstemperatur (22°C och 6°C) genom laboratorieförsök.Den genomsnittliga lagringstiden för matavfall från villor och flerbostadshus i undersökningen var sex dagar. Ett recept för matavfall har tagits fram med hjälp av litteratursökning och modifiering av recept i Avfall Sveriges rapport U2010:10. Laboratorieförsöken visade att skillnaden i metanpotential mellan plast och papper var tydlig vid 22°C, då metanpotentialen sjunker, men obefintlig vid 6°C.För att uppnå maximal metangasproduktion från matavfall under den varma delen av året så är plastpåsar bättre då de har en mer konserverande effekt på matavfallet än papperspåsar.

Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.

Spelmotor är benämningen på den komponent som hanterar en del av mekaniken i ett datorspel. Förutom funktioner för grafik, fysik etc. finns också funktioner för rörelser, interaktion med världen etc. I detta examensarbete går vi in på hur en spelmotor för morgondagens mobiltelefon kan se ut, samt vad dagens mobiltelefoners hårdvara och mjukvara saknar för att dagens PC-spel ska kunna portas till dem. Stödet för att spela avancerade spel på mobiltelefoner växer ständigt och inom några år bör hårdvaran vara ungefär densamma som på PC.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.
