Manual för elMaster Concept 2012
This thesis includes a description of the project flow for our projects at Semcon. The emphasis is on designing a manual for elMaster Concept.The project flow provides several minor and major elements plotting schedules for this project and the establishment of a manual. When a schedule is drawn, lists and tables with components and connections can be created. This is done to better manage drawings and make changes. These diagrams and tables are used in product manufacturing, testings, controls.
Vad får det lov att vara: en bok eller ett tv-spel? En studie om folkbibliotekens inköp av medier.
The purpose of this Master`s thesis is to examine if the pur-chase of media in public libraries reflects the library's role in society. Two questions have been posed: ? What view of public library's role in society is reflected in the purchase of media? ? What principles guide the selection of media in public li-braries in Sweden? In order to investigate these questions, we used a question-naire that we sent out to a sample of 120 public libraries in Sweden. The analysis is based on a theory of three ap-proaches to the role of the library developed by Douglas Raber. The three approaches are the conservative approach, the populist approach and the social approach.
Produktutveckling och prestandatest av ett vattenvärmedrivet torkskåp : Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.
Djurparkernas tillgänglighet av information och dess innehåll: är den tillräcklig?
The purpose of zoos has changed over the decades. From being menageries where wealthy people showed their collections of exotic animals to today?s zoos where science, conservation and education has become a central part of their work. Education in zoos gives them the opportunity to spread the knowledge about ecology, biology and biodiversity to the general public. Their aim is to change the public?s attitudes towards our wildlife and raise awareness about the threats that exists against our planets biodiversity.
Att spegla sin omvärld ? En exemplifierande fallstudie av Haninge kommuns biblioteksverksamhet
The purpose of this paper is to investigate in which aspects the public library is affected by its local community. This is re-searched by means of an exemplified case study of a Swedish public library in which we analyze governing documents and the library website with respect to environmental scanning and mar-keting of library services.The research questions are: How are the local community?s demands on the public li-brary being described in the governing document? How is the public library?s response to the demands of the local community being described in the operational plan? How are the demands of the local community, as shown in the governing document and the operational plan, re-flected in the marketing of library services on the library website?Our conclusions are that:The demands of the local community are described in a general fashion in the governing document, but there is a lack of concrete political guidelines.The public library's response to the demands of the local commu-nity is described to some length in the operational plan, but not with respect to economical factors.The demands of the local community are reflected to some length in the marketing of library services on the library website. Many of the overall themes that we identify in the governing document and the operational plan can be found in the marketing directed towards important target groups..
Vad väljer du? En undersökning av beteendepåverkande åtgärder för att skapa hållbara transportsystem
Människors transportvanor skapar idag tillsammans med andra faktorer ohållbara transportsystem. Jordens befolkning använder färdmedel som förbrukar icke förnybar energi i allt större utsträckning, vilket skapar transportsystem som inte är hållbara. Dessa faktorer medför en stor miljöpåverkan på vår jord och om vi fortsätter på samma sätt som de senaste 60 åren belastas jordens kretslopp allt mer, för att slutligen upphöra att fungera.Infrastrukturen idag motsvarar de behov och krav människor har på sin transportmiljö och dessa vanor bygger till stor del på vår historiska tradition av transport. Denna historiska tradition motsvarar inte ett långsiktigt tänkande. De beteenden och levnadsvanor vi har idag påverkar kommande generationers livsmiljö, vilken kommer att äventyras om vi fortsätter på samma sätt.
Riktlinjer för silodesign för massflöde
Det övergripande syftet med detta arbete var att skapa en övergripande sammanställning rörande ämnena flödesproblem och silodesign och specifikt ta fram riktlinjer för hur massflöde ska uppnås i silos för hantering av olika biobränslen. Dessutom syftade arbetet till att ta upp två autentiska exempel med flödesproblem och hur dessa kunde designas om för massflöde.
För att ta fram riktlinjer har arbetet utgått från värden framtagna av Wu, Schott & Lojdewijks (2011). Dessa har sedan bearbetats i programvaran Silo Stress Tool skapad av Dietmar Schulze (2013) för att utvinna gränsvärden för massflöde beroende av egenskaperna internfriktion, väggfriktion och vinkel på silons ficka.
Resultatet visar gränsvärden för massflöde för både cirkulära och rektangulära silos.
Folkbiblioteket ? en plats för social sammanhållning
The purpose of this thesis is to explore what possibilities Swedish public library has to work with and promote integration. The possibilities are examined on the basis of internal requirements of integration, the role of public library in the civil society and its policy documents. Further, the thesis examines what Swedish National library politics could contribute to this particular field. The experience of integration politics shows that a genuine commitment from all parts of the society is required in order to build an integrated society. The part of a society that public libraries are closest to and have the greatest impact on is undoubtedly the civil society.
Möllevångstorget : en fallstudie utifrån två platsteorier
We are daily using the public space to move throughout the city. The public space is an important part of our city and it?s where a lot of social activities occur and a lot of different events take place. The outdoor environment in the city should offer the residents nice and varying places for staying. In this essay I will try to understand how the physical environment works and how people moves and behave in the public space.
Spridning av släckvattenpartiklar : En studie på spridning av partiklar genererade från brand
During a fire large amounts of particles and unhealthy agents occur. Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.
Biblioteken och censuren: om försök att censurera HBT- litteratur på amerikanska folkbibliotek
The aim of this study is to look at censorship and attempted censorship of books about gay, lesbian, bisexual and transsexual (GLBT) people in public libraries in the USA. People from the public can submit formal challenges to a book at the library when they find the material offensive which can lead to those books being taken away from the library shelves. The questions asked are why GLBT- literature is being challenged, and sometimes banned, and how do the libraries deal with the challenges to the books.It is nowadays the people from the public, rather than the government or the librarians that are behind many cases of removal of books with homosexual themes. The study presents some of the fictional GLBT- literature that has been cause for much controversy in the USA. All the five examples mentioned are children?s books concerning GLBT- themes and are among the most challenged books in American libraries in the past twenty years.

The knowledge we hereby have acquired was subjectively evaluated in the thesis.The Swedish survey has a focus on meat and bread. The surveys in Finland and Norway contain all the products utilizing the studied return crate systems.We have surveyed how the handling of transport packages for meat & provision and bread is done in the store.
Metodik för detektering av vägåtgärder via tillståndsdata
The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.
Internetetik på bibliotek
The aim of this issue is to study how Swedish public libraries deal with the principles of freedom of speech and freedom of information in connection with public use of the Internet. The authors intention has been to find out whether the public use of the Internet has caused ethical problems for library workers and how the libraries solve situations when they consider their principles violated by library users. The authors study the debate on the issue in a couple of Swedish library magazines published during the late 1990s and they also give a few examples from the USA during the same period. They study the ethical principles and directives for schools published by the Swedish Board of Education as they claim that many of the public library users are students who bring along their ethical conceptions and thereby affect the ethical climate of the libraries. In their study the authors refer to ethical rules given to librarians by their trade union DIK and to the conclusions drawn from the hearing Good Ethics on the Net held by the Swedish IT Commission in 1998.
