Rena rör : Clean pipes
In this project a washing station has been constructed for Albany International AB. At present, there is no existing system to clean the dirty pipes that are coming back to the company.The work followed the product development process, and it started with the requirements list. This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.
Återväxt av blåbär (Vaccinium myrtillus L.) efter ångbehandling : orsaker till effektiv kontroll
Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.
Akka. Ett skrivbord för hemmet anpassat för rullstolsburna.
A woman is dying of cancer, she refuses to use her walking aid. Because she is embarrassed. This means she can?t leave her house, and her last days become very limited.Why do we act like this?Can the view we have of products adapted for disabled be changed by working with colour, texture, form and materials?There are many products adapted for disabled, the products often have a good function and well developed ergonomic aspects but the visual aspect leaves a lot to wish for. There is neither effort nor money put in to the exterior design of most of these products.A lot of the solutions that are invented for adapted products can be used in design of ?regular? products.Why should we then divide products in to adapted and non-adapted.
Self-organizing maps ? en atlas över informationsrymden
The purpose of this thesis is to examine how semantic relations in a document collection can be visualized with a Kohonen self-organizing map. It can be seen as a map of the information space which can be used to support information retrieval. The study makes a comparison of the possible differences between a map that is based on morphologically unprocessed text and a map where the text has been lemmatized. The text that is being processed is the definitions of all the existing instances in WordNet of a random selection of indexing terms from the Times-collection. The purpose is to see if morphological processing somehow can show different semantic connections between term instances based on their definitions.
Samband mellan laserdata och fältdata
To make it easier for forestry planning the forest owners needs data which describe characteristics of the forest. Such data you usually get from some type of inventory. A relatively new technology which probably is getting more important in the future, is laser scanning because of lower costs. But because the laser technology is relatively new you need to compare it with conventional inventory technologies to get better understanding of the possibilities the laser technology gives. This work intends to estimate field measured characteristics of the forest from laser data with help of regression analysis and then see which of the field measured properties that best could be estimated and which laser variables that gave the best results.
This study shows that heights has the best estimates, but biomass, diameter and volume also gives good estimates.
Hållbart skogsbruk och naturvård ? ett skogsägarperspektiv
The Swedish government has set up 16 environmental goals for Sweden to achieve. One ofthem is ?Living forests?, which is the foundation for the ?National strategy for the formalprotection of forests?. The ?National strategy? puts the private forest owner at the centre ofattention in order to achieve the environmental goal ?Living forests?.
Undersökning av mätsystem och regulatorstrukturer för industriella tillämpningar
This thesis is divided in to two different parts. The first part includes examination of the measurementsystem of an industrial robot using a resolver sensor. The main focus is on methods for suppressing noise in the angularvelocity signal without increasing timedelay. Five different methods are investigated. Three of these are based on oversampling: burstsamplingmethod, meanvaluemethod and correlationmethod.
Värdet av BIM i förvaltning. Möjligheter och krav.
This report aims to provide an insight into the particle physics of today, and into the research that goes on within the field. The focus is partly on the recent discovery of the Higgs boson, and partly on how software can be used to simulate processes in particle accelerators. Basic concepts of particle physics and the search for the Higgs boson are discussed, and experimental results, including those from the Large Hadron Collider, are compared with simulations made in MadGraph 5. Furthermore, simple new models of particle physics are created in FeynRules, in order to make simulations based on the models. To support the presentations of these aspects, some of the underlying theory is built from the ground up.
Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :
High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals.
Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.
Undersökning & Utvinning av Smartphones : En djupgående analys av positionsdata
The ordinary phone of today is not the same as it was 10 years ago. We still use them tomake phone calls and to send text messages, but the ordinary phone of today has muchmore uses, it is essentially a computer. To put into context to 10 years ago, it is a verypowerful computer, capable of processing wide array of information and presenting it tothe user. Nearly every single device today has a wireless connection, which makes everyuser connectable and able to use online services and internet at any time and place.This gives the user the possibility to integrate his or hers everyday actions with socialmedia and different search functions. Being able to search the internet for persons,restaurants, public transportation and a lot more is very useful to most.
A value chain analysis for timber in four East African countries : an exploratory case study
This study is a value chain analysis for timber in East Africa. It was commissioned by Vi Agroforestry, a nongovernmental organisation registered in Kenya, Rwanda, Uganda and Tanzania engaged in a rural development program that involves promoting tree planting and enterprise development (Vi Agroforestry, 2012). The purpose of the study was to identify and describe common value chains for timber in the countries where Vi Agroforestry operated.
Value chain is a concept and a framework describing how to structure information regarding activities included in satisfying a certain customer need, e.g. procurement, logistics, transactions, production and marketing.
Tankens makt - Påverkar abstrakt respektive konkret tänkande affekt efter en positiv händelse? En experimentell studie i en studentpopulation
The aim of this study is to through six interviews, with six experienced, social workers?, in three cities, understand how the child?s position in the Swedish child protective services? enquiries has change, and the factors behind it. The aim is also to compare if the social workers? view of the child?s position in the enquire has change accordingly to Socialstyrelsens intentions of BBIC. The theoretical approaches that was used is the new institutionalism, the Shier?s pathways to participation and the term discretion.
Jämförelse mellan sojaböna och åkerböna som proteinfoder till växande grisar
The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.
Förklaringsmodeller och behandlingsmodeller kring mäns våld mot kvinnor : En litteraturstudie
Young men who commit sexual abuse is a complex topic. This study is based on litterature on the subject and the material is processed through a qualitative content analysis. The study aims to study how the litterature describes the reasons why young men commit sexual abuse. It also aims to explore what is described to be effective treatment of young men who committed sexual abuse. The study found that most of the young men who commit sexual abuse comes from families where violence and psycohological abuse occurs. Many have themselves been victims of sexual abuse.
Svarstiden vid klinisk bedömning av högre språkliga förmågor hos vuxna
The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.
