Mät och loggningsutrustning för spänningstransienter
To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.
Graffiti i Karlstad : En konstform som väcker starka reaktioner
Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.
The Swedish liming operation : a study about liming officers opinions about some aspects regarding ecology, economy and organization
This is a study about the Swedish liming operation and the Swedish liming officer?s opinions of some aspects regarding ecology, economy and organization. The study objectives was motivated due to the recent changes in manuals for the assessment of limed waters and the suggested changes in decision making and decreased budget for liming. Moreover the anthropogenic acidification effects on the ecology are in many ways complex. Furthermore it was made in order to gain knowledge about the liming officer?s opinions in order to improve the ability to meet their needs regarding the assessment tools and also to investigate if other things can be improved concerning the liming operation.
Interactions between some plant-parasitic nematodes and Rhizoctonia solani in potato fields
The pathogenic fungus Rhizoctonia solani causes major economic losses for potato producers in Sweden. The producers, as well as advisors, have reported possible increases in severity of R. solani when free-living plant parasitic nematodes are present and active. There are several examples in the literature of interactions between pathogens where one, or both species, support or increase the damage made by the other organism. These complexes are important to investigate and to be able to forecast, since even low incidences of fungi or nematodes may result in an interaction of significance.
Med orden som bete : Identitet och framskrivande i Clarice Lispectors roman Levande vatten
Clarice Lispectors is one of Latin Americas most famous writers, and she wrote a number of books during her lifetime. Her novel Stream of Life (Água viva), which came out in 1973 and was translated into Swedish in 2007, is considered to be one of Lispectors most difficult texts to read. It consists of several fragments put together into one text; however the text has no traditional narrative or structure. It is the flow of moments that moves the text forward, as it is written down by the protagonist in the book.The primary aim of this essay is to examine how the protagonist in Stream of Life through different means, as the moment, the description, the word and the variations, creates an active participation in the formation of its identity. I will discuss the moment and its act of constructing the book?s circular structure, which is of importance.
Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
HUR CIRKULÄR EKONOMI KAN IMPLEMENTERAS I SMÅ OCH MEDELSTORA FÖRETAGS PRODUKTUTVECKLING
Dagens trend av industriell tillverkning och konsumtion är av linjär karaktär. Material utvinns, blir produkter och hamnar sedan på deponi. Detta examensarbete har tillsammans med Industrial Development Center AB syftat till att skapa en mer hållbar industriell tillverkning inom Skaraborgsregionen, genom att forma en produktutvecklingsprocess i enlighet med cirkulär ekonomi. Cirkulär ekonomi förespråkar att avfall inte får förekomma och att produkter och material ska cirkulera i kretslopp. Projektet bestod därför av en bred förstudie för att samla och utvärdera ett stort område med teorier, processer och företagens ansvarsroller.
Chalmersmodellens applicering på starkt överkonsoliderad lera
In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.
Vibrationsbaserad maskinaktivitetssensor
I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor medhjälp av en enkretsdator som genom en accelerometer mäter en maskinsvibrationer. Sensorn skall generera en statussignal. Accelerometern ger enmätbar signal baserad på maskinens vibrationer. Enkretsdatorn används för attsampla, transformera och analysera signalen och generera statusinformation.Med LabView kan vi spara, studera och analysera olika signaler och olikatransformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHzsampling räcker för att fånga intressanta vibrationer.
Effektmätning i pump
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
Time Machine Computing for Media Improvisation
C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.
YouTube och Musikbranschen : En studie i hur artisters användande av YouTube som marknadsföringskanal ser ut i en allt mer digital musikbransch.
Denna uppsats syfte är att analysera hur musikartister använder sig av YouTube som marknadsföringsverktyg, samt vilken betydelse YouTube har för dessa artisters marknadsföring. En kvalitativ och induktiv metod har tillämpats, medan ett antal intervjuer samt en innehållsanalys genomförts som grund till det empiriska materialet. Detta för att få en inblick i musikbranschens syn på ämnet, samt även ge en objektiv bild av hur plattformen används som marknadsföringsverktyg. Slutligen menade studien att ge artister och andra arbetande inom musikbranschen, en bild av hur användandet av denna marknadsföringskanal kan förbättras för att skapa en mer effektiv marknadsföring. Den teoretiska referensramen har utgått från tidigare teorier kring YouTubes betydelse, roller och potential inom musikartisters marknadsföring. Teorier kring YouTubes möjliggörande för artister att upptäckas av A&R personer eller nya fans, YouTubes påverkan på musikvideons roll som marknadsföringsmedel, samt teorier kring plattformens påverkan på maktbalansen inom branschen har legat som grund.
Att känna sina elever : Fem lärares förhållningssätt till att undersöka förkunskaper hos elever med migrationsbakgrund
This study aims to give an account of five teachers? views and understandings of second language (L2) learners? previous knowledge, as well as, their linguistic and cultural backgrounds. This is carried out by the means of qualitative interviews, where the sampling consists of five primary school teachers at various schools. The findings are presented and analyzed using a thematic analysis. Furthermore, the study indicates that teachers in general have a positive attitude to learning more about their L2 learners? prior knowledge and backgrounds, both for the pupils, as well as, their own sake.
Delningens dolda drivkrafter: En fallstudie av Fixoteket i G?teborg
This study examines how perceived accessibility and distance decay interact with social and psychological factors in the use of local sharing initiatives. The study is conducted as a case study of Fixoteket in Gothenburg, with Fixoteket in Hammarkullen as primary focus. Through five semi-structured interviews and five participatory observations at Fixoteket in Hammarkullen, Ranneberg and Fr?lunda, this study analyses which factors function as barriers and enablers for participation, as well as what benefits the initiative generates beyond resource efficiency through sharing.The results show that social factors such as community, a sense of belonging, and social rituals around visits constitute the primary drivers for participation, while psychological barriers, related to competence, shame and digital exclusion are the most significant barriers. Distance decay proves to be a relative, rather than an absolute phenomenon, where visibility and social presence dictate the significance of physical distance.
Inventering och riskklassning av förorenade områden i Öna och Östnor :
This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.
