The organic farmland is increasing all the time and the goal is that 15 % of the Swedish farmland will be in organic production in year 2010. The organic production needs new and more effective ways to control weeds, and there is the row harrowing coming as a good complement to the conventional weed harrowing. In this experiment is weed harrowing whit different row spaces and row harrowing with a spacing of 25 cm compared. Then are the weed picked and the weight taken of them. The yield is compared in the 7 different ways of treatment. The results is not showing any significant differences in yield even when the row spacing is 25 cm instead of 12,5 cm. Even the spring wheat that is a sensitive crop and has bad tillering is doing well in this experiment. Now with modern technology where the row harrow is controlled by a camera that making the row harrow to follow the rows is it the soil coverage of the crop that is the limit for the speed. With wide machinery is the very good coverage even with a row harrow..

Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

Gestaltningsförslag till nybyggd villa i Kivik med hänsyn till i huvudsak ståndorten. Tomtens öppna läge göra att den är utsatt för stark vind och marken består till större delen av sand, vilket ställer ett högre krav på det valda växtmaterialet. Omgivningen består av hästhagar, ett villaområde från 70/80-talet och ett ljust och öppet läge med naturen som bakgrund, vilket har en stor påverkan på trädgårdens design. Huset har en modern arkitektur och skiljer sig från den övriga bebyggelsen och utmaningen har varit att integrera detta till den övriga omgivningen med hänsyn till den speciella ståndort som finns på platsen.

Abstract: The purpose of this study was to examine the Swedish industry- and craftmanship trade, specifically the relationship between effort and reward and how it affects the meaningfulness during labour hours. Also, what are the possible effects on production efficiency as a whole? Discussed and analyzed through empirics and previous research.38 workers filled out a survey and two interviews were conducted to get a more analytic depth to the data.The results showed that there is little to no reward for high effort during labour hours on the evaluated workplaces, combined with low commitment and meaningfullness. My conclusions are that more ways of effort-based rewards would likely have a positive effect on meaningfulness and thereby the production as a whole. I also show that the theses of Karl Marx are still plausible and relevant in modern day industrial- and craftsmanship trades in capitalist countries..

Quality assurance of construction projects and create effective ways of working, is intoday's pressed position, major objectives for building contractor companies. This thesis is an attempt to see if it is possible to achieve these goals with the new modern tool iPad.The author of this thesis has during the latter half of his one year practice work in Uppsala for the Swedish building construction company NCC Construction Sverige AB, conducted a study on the possibility of using the iPad on an construction site. This has been done with active field studies in which applications have been tested and also the supervisors receptive. The usability of the iPad has always been in focus since it is important that the applications are easy to use and easy to learn.The results of the work, as presented in this report, points at opportunities in efficiency if the iPad is introduced and used on construction site. There are many useful applications for the iPad, and with a system that can handle the synchronization between the iPad and the computer, the workflow will be streamlined significantly..

Under 1990-talet accelererade avvecklingen av det fasta kustartilleriet. Det skedde samtidigt med implementeringen av Revolution in Military Affairs(RMA)-konceptet i Sverige, snabb militärteknisk utvecklingen och Försvarsmaktens omställning från en stor organisation med lång mobilisering till insatsförsvar med hög beredskap. Syftet med studien är att med hjälp av argumentationsanalys och kvalitativ textanalys, studera relationen mellan RMA och avvecklingen av fasta kustartilleriet, genom analys av Kungliga Krigsvetenskaps Akademiens Handlingar och Tidskrifter. Resultatet visar att fast kustartilleri spelar en viktig roll även i en värld präglad av RMA och modern teknologi. Det fasta kustartilleriet ersattes av rörligt.

Syftet med detta examensarbete är att skapa en helhetsbild av vilka faktorer som låg bakom bildandet av ett lågprisflygbolag inom SAS koncernen. Det vill säga: Vad initierade SAS att starta ett lågprisflygbolag? För att kunna svara på vår frågeställning valde vi ut ett par olika inriktningar och synsätt på strategi inom modern företagsekonomi. Vi applicerade sedan dessa på företaget vi valt att studera och analyserade händelseförloppet utifrån förutsättningarna som gavs. Slutsatsen på rapporten konstaterar att det finns tre huvudanledningar bakom SAS lågprissatsning.

With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. Avsikten är att underlätta valet av SIP-server för nya applikationer inom IP-telefoni, öka prestandan samt snabba på utvecklingen. Studien behandlar de intressantaste faktorerna vid val SIP, såsom användarvänlighet, hastighet, lagring av användardata samt ljudkvalité. Slutsatsen blev att Kamailio stod som klar segrare, med överlägsna resultat i jämförelse med övriga servrar, på de parametrar som valts ut.

The purpose of this study was to investigate how two students at intermediate level in reading and writing disabilities and two special education teachers perceive the use of assistive tools in school. The questions used to answer the purpose was how assistive tools are used based on students´ perceptions, the purposes for which assistive tools are used based on special education teachers´ perceptions, what opportunities and/or barriers pupils and special education teachers experiences with assistive tools and how it works when assistive tools are implemented based on students´ and special education teachers´ perceptions. Data were collected by interviews. The results show that the assistive tools are mainly used for writing assignments and to ?read-with-ears?, primarily to facilitate the learning process in the classroom.

I norra London startade, den sjätte augusti 2011, ett av de största upploppen i modern tid. Syftet med denna teoretiska uppsats är att - inspirerat av londonupploppen - diskutera olika teoretiska sätt att förklara och förstå händelserna ifråga, med särskild fokus på relationen mellan strukturellt och direkt våld. Styrande teman är socialt utanförskap, skam och vanmakt. Analysen indikerar att det sociala utanförskap som strukturellt våld och relativ deprivation skapar är grogrunden för vanmakt och skam ? två känslor som är intimt förknippade med direkt våld.

Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management control system is primarily a traditional one which is rather strong in terms of Levers of control.

This paper set out to investigate how teachers of Swedish in Sweden implement the grammar objectives of the curriculum in their teaching, through interviewing six teachers. It has been important to compare their methods to modern research of grammar teaching and teaching in general. They have been asked a series of questions to answer whether or not they use grammar terminology as mediating tools, if they intergrate dialogue among students in grammar teaching and to what extent the teachers? knowledge of and attitude towards grammar influence their teaching methods. The results show that grammar is used as mediating tools primarily when it comes to feedback on pupils? texts, though not to a great extent; dialogue between pupils is rare when it comes to grammar teaching; and the teachers? grammar knowledge and attitude affect the teaching methods, primarily in the sense that seeing value in grammar knowledge increases the teacher?s desire to develop new methods for grammar teaching..

En stor del av de svenska byggnaderna uppfyller inte de krav som ställs för taksäkerhet, och saknar taksäkerhetsanordningar. Detta beror på att de taksäkerhetsanordningar som finns på marknaden idag inte tilltalar kunden tillräckligt estetiskt. Dessutom finns en stor variation av taktyper, detta har medfört att det utvecklats många olika infästningar för taksäkerhetsprodukter. Målet är att utveckla taksäkerhetsanordningar som kunden anser vara estetiskt tilltalande samt konstruera en infästning som fungerar för alla typer av tak och alla taksäkerhetsprodukter. Resultat: Flera koncept togs fram med fokus på design och tillverkning, där till slut ett slutkoncept valdes för infästning, snörasskydd och nockräcke samt två koncept för stegar.

Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.
