Experimentell konstruktion av pickupsystem anpassat för trummor med hjälp av MATLAB
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Värdeflödesanalys på Saab Training Systems i Huskvarna
Saab Training Systems (STS) in Huskvarna is manufacturing material for educationalpurposes to armies worldwide. They are now implementing parts of the Lean productionconcept in their organisation.One part of the work with Lean production is to eliminate waste. To be able to identify waste,value stream mapping is a good tool and also what we used in our thesis. To gain a betterefficiency in the production of Personnel Detector Device (PDD) flow was one of our goals.The PDD is a harness used during battle training which registers if the user is being hit by itsenemy.Our work with the thesis started up with a short education in Lean production and in valuestream mapping (VSM). The work proceeded with a VSM of the production flow of the PDD,interviews were made and studies of literature were done to gain greater knowledge of thesubject and solve the task.The VSM resulted in five areas which were followed up out of those six we identified.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
Framsta?llningen av barn i den nya sexualbrottslagen : en inneha?llsanalys baserad pa? fo?rarbeten
The last major change occurred in 2005 when the new sexual offenses law came into force with an increased focus on children. The purpose of this study is that through a content analysis to identify and understand the construction of children in the new legislation on sexual offenses on the basis of preliminary work. Based on the purpose we came up with two questions: How are children constructed in the preparatory works to the new sexual offenses law? Are they attributed to child characteristics and responsibilities in the new legislation on sexual offenses and if so, how? In order to achieve the purpose of the study we have chosen the preparatory works to the new legislation on sexual offenses from 2005 until today. The study's empirical work has been further narrowed to the children, which means that a distinction is made in the new legislation on sexual offenses to 6 chapter 4-6 §§.
?Less is more? : En studie om hur knapphet påverkar köpbeteendet
Scarcity due to supply, demand or in time is all factors that affect consumers´buying behavior. The scarcity principle describes how scarce resources appear moreattractive to the customer's eyes than unlimited does. When something is scar thecustomer often draws parallels to the quality and price, that the product will bemore expensive and better. People hate to be deprived of choices. When a certainproduct is scar, the customer will desire the product even more.
Energikartläggning av biogasanläggningen, Kungsängens gård
The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production.The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with thenmeasured time of usage.

Återvinningsstationer på Lidingö : attityder och lokalisering
When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

Mänsklig påverkan på mindre vattendrag i skogslandskapet : en inventering av vägtrummor och skyddszoner kring dessa i Uppsala län och norra Västmanlands län
Interference in an ecosystem means a disturbance. When harvesting, forest roads have to be
build to cope with heavy duty vehicles. Crossing brooks can not always be avoided. In this
case bridges or culverts have to be built. There are many different kinds of culverts and
depending on what type you choose and how you place the culvert, the watercourse and the
water organisms can be harmed in different ways.

Flipp eller flopp?: En kvantitativ studie om bloggens potential som marknadsföringsmedium
The blog has become a widely discussed subject, but while marketers do invest in blogs, there is little evidence on the how the blog works as a marketing tool. Therefore, we thought it would be interesting to create a greater understanding of the blog's potential communication effects. To demonstrate the potential of the blog in comparison with more traditional media, we decided to compare the communication effects achieved by a blog with those achieved by an online magazine. We pursued an experiment where we exposed an identical text about a brand to respondents in seven blogs and in seven online papers and measured the resulting communication effects in terms of attitudes and intentions towards the exposed brand. The quantitative study showed that the blog in some basic aspects works as a more traditional media; when the consumer forms positive attitudes toward a text in a blog, the attitude spills over to the attitude toward the brand, with higher buying and w-o-m intentions as a consequence.
Prefabricerat trähusbyggande med moduler : För- och nackdelar samt förslag på vidareutveckling
The construction industry can contribute to a healthier sustainable community. A development that is going on right now is by using more prefabricated volume- and plan elements on the construction sites. Building with this method not only provides a benefit to the environment, but also reduces production rates by taking up to 80 percent less time to build. By building in this way it will be easier to recycle and keep all the material that otherwise would go to waste. Also by building inside a protected environment, the material retains its good quality.This report will take forward proposals on further development of prefabricated volume element of wood, by first presenting this construction methods advantages and disadvantages..
