Utveckling av heltäckande gångbord
This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..
Geosynteter för hållbara vägar : Modell för jämförelse av vägöverbyggnader med eller utan geotextiler och/eller geonät
The different material layers as part of a road construction fill all a function so theroad becomes durable, safe, comfortable and aesthetically pleasing. Recently, anew group of construction materials started to play an important role in roadconstruction ? geosynthetics.This thesis addresses the two most common types ofgeosynthetics used in modern road construction, namely geogrids and geotextiles.The most common use of geogrids is reinforcement of poor subgrade by usinggeogrid soil reinforcement, which occurs when road material particles wedge inthe geogrid?s mesh. Geotextiles act partly as a barrier that prevents the finermaterial in the below ground from being mixed with coarser upper material andalso act as a load spreader.Road contractors often face a choice of whether geogrids and/or geotextiles areappropriate in a particular road project and also how much profit the choice mightbring. This phase in the tender calculation process is the intended scope of thisthesis.The thesis deals with both the "hard" cost-function aspects and the "softer" values e.g.
Hallbyggnadsteknik - en effektivisering av småhusproduktion
Syftet med det här examensarbetet är att undersöka om det är möjligt att överföra hallbyggnadsteknik till produktion av småhus för att sänka produktionskostnaderna. Studien visar att hallbyggnadsteknik enkelt går att överföra till en villa. Dessutom blir det billigare att bygga klimatskalet med vårt byggsystem jämfört med ett traditionellt prefabricerat småhus. Genom detta system kan den totala byggkostnaden för villan i jämförelsen sänkas med 3-10 % beroende på vilket fasadmaterial som väljs..
Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya
Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.
Crossbreeding in dairy cattle
The aim of this literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.
Hållbara uppvärmningsalternativ för Grinda Wärdshus : En studie om uppvärmning med pellets och flis
This report is a bachelor's thesis of two students from the Energy and Environment degree at KTH Stockholm. Grinda is an island situated Stockholm archipelago. Skärgårdsstiftelsen is landowners and manages the area. Grinda Wärdshus, a guest house located in the island, currently uses an oil-fired boiler as a heating system. The aim of this thesis is to investigate whether wood chips or pellets is, from a sustainability standpoint, a suitable heating method for the guest house.
Lagafors CPU : Chemical Production Unit
This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .
Landskap för spontanidrott :
"Landscapes for Spontaneous Sport"
The main aim with this degree thesis is to show how planning and design of urban space can promote spontaneous sport. Public health and urban life would benefit from re-introducing the sport and physical activity in the townscape.
The study can be seen as an "inspiration book" that focuses on the connection between sports and landscape architecture. The starting-point for the discussion is the fact that the spontaneous sport is on the decline and the main general question is how this negative trend could be broken. In particular the study asks how landscape architecture could promote and increase spontaneous sport.
Good examples of places for spontaneous sports of different kinds are given, both from Sweden and from other countries, which have inspired a case study where I propose a redesign of a centrally located, but hardly used park in Skäggetorp, a suburb of the town of Linköping.

Mail Exchange Protocol (MEP): Ett utkast till nytt protokoll för elektronisk post
SMTP, the current protocol for sending electronic mail (e-mail) over the Internet, has for many years suffered from several problems and limitations. When it was designed, well over twenty years ago, the requirements for e-mail were very different from those of today. A message was a text message in English, and both user and machine were explicitly named in the address. The protocol was not designed to transfer other types of messages, and no mechanism was included to verify the identity of the sender.In order to solve these shortcomings, a new e-mail protocol needs to be defined. This report specifies a basis for what such a protocol may look like.
Personlig Assistans : utifrån assistentens perspektiv
Personal assistants ' descriptions of their own professional role are usually removed for the benefit of users ' description of the profession. The purpose of this study is to investigate how the assistants perceive their profession by providing assistants a possibility to talk about their experiences of the profession. Data has been collected by twelve interviews with active working personal assistants aged 22-57 years. Assistants interviewed have different experiences and working with people with various disabilities. The method used is a qualitative method with a narrative analysis method, where the twelve interviews have been merged into four fictional stories.
En utredning av det Systemvetenskapliga programmet : En studie om kontakten program och näringsliv i Umeå har och vad de anser om systemvetare och certifiering.
Certifications is common for IT in relation to individual program languages or program applications. Certifications for educations that endures several years is not as common to see. In this paper the situation for the Systems Science programme is researched, by investigating how the programme looks around in Sweden. Also by using interviews, show how companies and people responsible for the programme in Umeå, think the contact is between them and how the knowledge of the Systems Science students are from the view of the companies that employ them. In the end the conclusions show that there are differences in the Systems Science programme, and that the companies have quite a similar view of what the Systems Science students are good and not so good at.
Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp
The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.
Shelter use of horses during Swedish summer in relation to weather conditions and insect abundance
Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse
weather conditions such as high or low ambient temperature, heavy rain or strong winds.
In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment.
The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters
C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.
En bostadsrättsförenings påverkan i kommunikation genom en Internetportal
Internet has given possibilities to a whole new world within communication. Nowadays the communication inside organisations and companies takes place through the Internet. The idea of this paper arose when one of the authors discussed the general involvement of the tenant-owner?s association in the committee. Providing a new channel for communication through a homepage could affect the attitude of the tenants. We were curious of what effect on communication introducing a homepage would give.
GRAFISK PROFIL TILL EN BLOMSTERHANDEL - corporate identity for a flower shop
This project aims to explore how to create a working concept-based flower shop visual identity, with focus on brandig, eco-branding and visual communication.
My main question is:
How do I create effective visual communication for an ecological flower shop?
The results of this thesis are that there are things to consider when creating a visual identity with an ecological concept. The most important question is if there is any benefit for your company to go green, otherwise positioning of your company will be hard. What I realized during the design part of my project was that if I use the methods described in this thesis and consequently applying my choices after the flower shops identifying words, a working concept-based visual identity will be possible to create..
