Buskröjning längs skogsbilvägar : en produktivitetsstudie av två kättingslagor
To regularly remove woody vegetation along the roadside of forest roads is an important part of the road maintenance, since the vegetation binds moisture in the road side and, thus, the removal makes the road drying faster with results in improved bearing capacity. Vegetation removal also makes it easier to upgrade the road by material recycling from the ditch and, moreover, the visibility along the road is maintained.The aim of the study was to evaluate what type of chain flail is the best and most cost-effective for removal of different kind of woody vegetation along forest roadsides.Time studies were made on two chain flails when removing woody vegetation in three different classes; easy-, middle- and heavy shrub removal. The studied flails were one light and rather simple flail named Optimal M160 and a heavier and more advanced flail named Slagkraft H210. The removal was made according to Holmen Skogs? specification and the quality of the cleaning was measured by objective belt inventory.The productivity was higher with the heavy flail within all cleaning classes.
Trädetaljer i exteriör arkitektur : En rapport om hur arkitekturen kan tillåtas framhäva trä som byggnadsmaterial i utvalda exteriöra detaljer för ett äldreboende med massiv trästomme
Arkitektfirman Kolman X Boye Architects har fått uppdraget att upprätta bygglovshandlingar för ett äldreboende. Det är ännu ej bestämt i detalj hur byggnaden skall uppföras men beställaren önskar att byggnaden uppförs i träbyggnadsteknik. Äldreboendet projekteras för 54 stycken lägenheter fördelat på sex stycken våningsplan och en total bruttoarea på strax under 6000m2. Ingen lika hög träbyggnad med denna verksamhetsklass avseende brand har tidigare uppförts i Sverige.Vår uppgift och utmaning i detta arbete har varit att reda ut problematiken kring projekteringen av exteriöra detaljer för höga hus i trä. Utifrån kända problem avseende brand, akustik och fukt har sedan ett antal detaljer som påverkar det estetiska uttrycket projekterats.

The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.
Inskolning på förskolan : Undersökning av två inskolningsmetoder
When the introduction starts for the child and their parents it holds many emotions. There are many emotions involved in the first meeting between preschool and home for both the children and their parents. So my purpose with this study is to focus on two introduction models educators at my selected preschool works by. The purpose of my study is to focus on the two introduction models that are used by educators at my selected preschool. I ´m going to view this two models by examining how the educators prepare before the introduction starts and look at their point of view.
Elektromagnetisk skärmning genom mekanisk omkonstruktion
This is a master degree thesis at Royal Institute of Technology (KTH) betweenÅngpanneföreningen and Programma. KTH is the examiner, Programma is the client andÅngpanneföreningen is mentor for this project.Programma has a product called TM1800 that has problems with EMC; the problem is thatthis product does only pass the CE-check with a small safety margin. This problem can besolved by reducing the radiation from the electric components in the product or by reducing offix base frame. In this degree thesis the focus is only on mechanical redesign.The main problems right now depends on the long distance between the screws, there is anisolating layer on most of the parts and the forces between the joints are too small. The mainfocus is to solve these three problems.The best solutions are when the whole base frame is more or less redesigned instead of onlyredesigning some of the connection points.
Den offentliga bilden av äldreomsorgen : en diskursteoretisk analys av artiklar i Dagens Nyheter under 2006
The purpose of this essay has been to examine the public`s view of the Swedish eldercare during 2006. This study uses discourse analysis as a research method, the reference material has been articles from the newspaper Dagens Nyheter. The aim of the research has been to find central themes, conflicts and consensus in the discourse of eldercare. The analysis resulted in four main subjects which were based on four main questions; the questions of responsibility and execution, the question of contents, and the question of where the eldercare should take place. The analysis of conflicts and relations of consensus in the discourse of eldercare resulted in two different main views; the traditional and a more modern.
Kontaktpressningssystem : En studie av elsäkerhet
This work covers a broad analysis of the risks that could impact the achievement of electrical safety of electrical installations. The work includes both electrical equipment such as the installation of electrical equipment.The report illustrates the main technical characteristics of electrical connections greater than 10 mm2 and provides an introduction to the crimping systems for copper and aluminum conductors. In addition to that analyzes the factors that are important to assure the quality of an electrical connection throughout the value stream in terms of both materials such informations. Furthermore analyzed deeper the need for skills development of technicians and other staff.The different parts of this work are analyzed and presented, in theory to studies carried out both at Elpress AB and partly with the help of other scientific reports dealing with similar subjects. In addition, presents a survey that will help understanding the current perception of the electrical connections and cable crimping systems among end users.
Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv
Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.
Hybriddrift i stridsfordon, fördelar och nackdelar
Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.
Safire : Unik brandvarnare med smart design för ökad säkerhet
Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.
Vem är normal?
My project is about attitudes towards disabled people, about our fear for those who are different, about acceptance, ideals and normality.My inspiration has been prosthesis, and mostly people that are born without limbs. Through my research I have come across a lot of questions. Such as, why is a prosthesis so important and for whom? Why is it so important to be normal? What is normal and for who? People that are born different se upon themselves as normal, until they realize that others don?t. Many of them want to learn how to deal with life without prosthesis. And therefore they reject these. Sometimes the prosthesis is aids that are highly necessary.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.
Hastighetsreduktion på genomfartsleder, genom icke-tvingande åtgärder i vägmiljön
The study was conducted with an landscape approach with an subject related approach in the field of environmental psychology to investigate how road design affects drivers' choice of speed. The purpose was to portray road environments on thoroughfares in urban areas to motivate motorists to keep the speed limit and thus increase road safety for vulnerable road users. The task question was formulated, how can thoroughfares in suburban settings be portrayed to motivate motorists to reduce speed?
The study was conducted throughout a literature review of motivational speed measures along with interviews with road design experts at the Swedish Transport Administration. Case studies were conducted on three thoroughfares in the Stockholm suburbs Vallentuna, Upplands Väsby and Danderyd.
