Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys
The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.
Public Service i framtiden : En kvalitativ studie om hur SVT förhåller sig till Public Service-idealet på webben
Public Service är ett svårdefinierat begrepp. De gamla idealen handlar mycket om enmedieideologi som baseras på etermediernas möjligheter och begränsningar, vilket har skapatsvårigheter när Public Service har letat sig ut på Internet. Kritik från bland annatbranschorganisationen Tidningsutgivarna ifrågasätter Public Service-företagens breddning påwebben. De anser att gränserna för vad Public Service-företagen får och inte får göra äralltför otydliga.Med hjälp av fyra kvalitativa samtalsintervjuer (tre personer från Sveriges Television samt enfrån Tidningsutgivarna), och med kvalitativa textanalyser av statliga propositioner ochutredningar angående Public Service-uppdraget undersöks hur Public Service-uppdraget ochdess medieföretag påverkas av medieutvecklingen.I uppsatsen jämförs resultaten med Anna Maria Jönssons tankar kring Public Service och denmedieideologiska inriktningen ?Social ansvarsideologi?.
Planseparerad spårtrafik i Göteborg
The City of Gothenburg has an urgent need to upgrade its public transport. The capacity of its light rail transit (LRT) has reached maximum capacity within the inner city limits years ago. The construction of an underground metro will be very expensive and time consuming due to the soft clay beneath the city. The apparent need of developing another type of mass rapid transit (MRT) is urgent. An elevated metro have turned out to be a success in Greater Vancouver, but is it possible for the system to operate well in Gothenburg with its narrow streets and current land use; will its route coexist with the current LRT or will the noise disturb people too much?.
Porr och rasistisk propaganda på svenska folkbibliotek : skall folkbiblioteken tillåta ett fritt internetanvändande eller skall man kontrollera sina internetterminaler?
This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.
ATSVIS : Airport Traffic Surveillance and Visual Information System
Det primära målet med examensarbetet var att utforma ett koncept på hur man kan göra flygtrafiken säkrare både på marken och i luften. Konceptet fick namnet ATSVIS, vilket står Airport Traffic Surveillance and Visual Information System. ATSVIS är tänkt att ge anvisningar om vad nya idéer och ny teknologi kan tillföra piloten och trafikledningen. ATSVIS avser även att automatisera och förenkla flygtrafiken, vilket skall leda till säkrare flygtrafik både i luften och på marken. Konceptet ATSVIS kommer att utformas efter egna idéer och från intervjuer med branschfolk.
Elevers förståelse av fotosyntesen och dess koppling till andra organismer
The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.
Systemanalys av skogsbränsletransporter :
At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
Opera i Stockholm : Stadsgårdskajen
The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..
Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
"Allt det där ska samsas i ett och samma yrke": en studie om folkbibliotekariers yrkesidentiteter

New public management och den svenska gymnasieskolan : En ideologikritisk analys av Gy11-reformen kopplat till organisationskonceptet new public management
The purpose of this ideology critical study is to investigate the hidden content in the reform Gy11 and compare it with the concept new public management. After the clarification of the hidden content, we compare the structure of the organization in Swedish high schools with the structure in public sector called new public management. The main questions of this study are the following: Is it possible to see the foundation of new public management in the Swedish high schools when it comes to the views of knowledge and the formation of goals? Which similarities can we find when we look at the organization new public management and the Swedish high school?The result showed many similarities, both regarding the views of knowledge and the formations of goals. The structure of new public management has been largely implemented in the Swedish high schools and the schools now focus more on instrumental knowledge rather than universal knowledge based on understanding.This is not surprising due to the social progress.
Vad förvaltningen bör sträva efter : -riksdagspartiernas uppfattningar om de värden som förknippas med förvaltningen
The values politicians relate with public administration are likely to affect the way that they want the public administration to be organised. The purpose of this study is therefore to examine which values Swedish parliamentary parties relate with public administration and more particularly how they emphasise these values.The study is conducted as an analysis of theoretically relevant bills that the government party and the parliamentary parties have introduced to the Riksdag, and reports and statements of opinion from the parliamentary committees. The documents are from the Riksdag´s sessions from 2000/01 to 2005/06. After examining the documents the conclusion can be drawn that the value that is most emphasised during the period is legal security. This might mean that legal security will have more influence on the decisions taken about the organisation of Swedish public administration..
Effekten av rollkur på hästens rörelsemönster och välfärd
This essay intends to provide an understanding of the developments in the right of public access and recreational activities in the forests of Sweden, and which factors and prerequisites that have affected this development. The forest and its history, along with recreational development has in many ways shaped today?s rights of public access, but there is also an age-old tradition of public access that has affected how we have used the forest, and that also has enabled the development of outdoor recreation. Many are unaware of this, which causes misunderstanding to appear around the rights of public access and how it is supposed to be used.The essay opens with historical descriptions of public access, the Swedish forest and outdoor recreation, to thereby provide a picture of how these three fields have influenced each other over the centuries. This is followed by a description of the current access rights and the problems associated with those, and a description of other countries' equivalent of the right of public access.
