Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper

Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

Mens : Himmel eller helvete?

The goal in doing this study has been studying public interpretations of media content in the commercials that this study uses. The analysis was based on two TV commercials for feminine hygiene products. Initially, they seemed to differ from each other, but soon the question whether or not they in fact did convey the same underlying message was raised. The theoretical premises on which the study was founded on are the gender perspective in advertising and the social construction of gender. To reveal the hidden signs appearing in these commercials and to find out their meanings, we used the method of semiotic analysis.

Lagringstidens påverkan på metanpotentialen i matavfall

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.

Sambandet mellan saldodifferenser och effektivitet : En fallstudie på utomhuslager inom Sandvik Materials Technology

To meet the needs and demands of the costumer, accurate information about how much is available in stock is necessary. When the information in the system does not match the physical inventory, inventory inaccuracy occurs. Inventory inaccuracy is common among companies and may contribute to increased labor cost, excess inventory, production disruptions, waste of time, late deliveries, poor service and lost customers.The purpose of this study is to identify contributing factors to inventory inaccuracy for business with outdoor storage. The study also aims to investigate how efficiency factors can reduce the inventory inaccuracy for business with outdoor storage.A case study was conducted to answer the purpose. A company in the steel industry was chosen to examine inventory inaccuracy on business with outdoor storage.

Punktmolnshantering i anläggningsprojekt : Utvärdering av programvaror för framtagande av markmodell

An increased number of participants in the construction industry is asking for accompanying terrain models to the project in order to get a better understanding of the field. When the desire to create buildings that fit together nicely with the surrounding area is increasing, it becomes more and more important to have a broad base of knowledge about the ground on which the building is to be erected. Terrain models are also very useful in the planning of logistics, documentation for landscape architecture projects, and billings for mass calculations.Surveys for creating terrain models can be performed with laser scanning. The advantage of laser scanning is the time-effective surveying, the detailed information as well as the ability of application in complex environments resulting in a cost-efficient project. With this in mind our thesis was defined in collaboration with the company Bjerking AB in Uppsala in order to investigate if there were any softwares suitable for terrain modeling.

Attityder på byggarbetsplatsen : En studie om den psykosociala arbetsmiljön

Byggbranschen är en olycksdrabbad bransch. År 2007 skedde 3114 olyckor och 16 dödsfall. Många teorier och förklaringar har gjorts i olika publikationer som visar på problemet. En oro finns inom branschen som riktas mot den höga olycksstatistiken. Det kan vara svårt att lokalisera de brister som orsakar olyckor och ibland kanske man blundar för viktiga faktorer.

East Side Story, a West Side Story? : En Kritisk Diskursanalys av Afghanistankriget i Västerländsk Nyhetspress

The purpose of the study is to expose how the US newspaper New York Times and the Swedish newspaper Dagens Nyheter mediate the war in Afghanistan. Furthermore a comparison is done to map out possible differences and similarities. To fulfill the purpose of the study a critical discourse analysis has been used. The results have shown both differences and similarities between the newspapers. The main conclusions are tendencies of correspondence with previous research and theoretical base, such as the furtherance of elite sources, the promotion of the national political agenda and the national identity and an obvious construction of us and them..

They also got a chance to tell us what they thought about the whole idea with the Intranet.

Kommunikation, uppföljning och tidsplanering inom detaljprojekteringen : Hur projekteringsprocessen kan effektiviseras med små medel

Producing a building is a long and complex process. It consists of several parts, from the feasibility study and design stage onto the construction and finally the management of the building. The design process is a critical part of the process where construction plans are made. The quality of the plans affect the production phase in great extent and faulty plans can pose a risk for extra costs for all parts in the process. The cost of producing dwellings has increased the last years and the detail design process is one of many phases where improvements can mean cost savings within the whole building process.This report aims to point at parts within the detail design process which could be more efficient, regarding communication, follow-up and time planning, and to give suggestions for improvements.

Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Försvarsenhetens arkiv : Examensarbete på länsstyrelsen i Södermanlands län

The defence unit´s archive stretches over a time limit between the middle of 1971 to the end of 1987. The records the archive mainly contains are concerning the civil defence, inspection and construction of shelters, war- and crisis planning. The majority of the records are registered record, as often is the case with an authority?s archives. The main problems that occurred concerned what should or shouldn´t be public, the principle of provenance and what to prioritize; finish the project before deadline or make sure the records are prepared for a storage that ideally should last for several lifetimes..

Aquaculture : animal welfare, the environment, and ethical implications

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.
