I vatten eller jord? : Nytolkning av depåfyndet från Eskelhem
In 1886 Hans Hildebrand received a Bronze Age hoard found in a field that belonged to Eskelhem´s rectory. A record was made where Hildebrand presented and documented the artifacts. The following year Oscar Montelius reviewed the artifacts, which he described as horse gears. He compared the horse gears with similar artifacts found in Europe that roughly had the same dating in order to trace the origin of the hoard. Montelius conclusion was that the hoard was created on Gotland around 500 BC.
FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation
The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.
Förstudie:tillverkningsmetoder för ny kägelteknik till hydraulventiler
Syftet med examensarbetet är att ta fram förslag på tillverkningsmetoder för ny kägelteknik som skall bli ett komplement till dagens slidteknik, som används till hydraulventiler. Inom ramen för examensarbetet skall olika tillverkningsmetoder för två detaljer som räknas som strategisk kritiska undersökas. Ett viktigt ställningstagande i denna process är om detaljerna skall köras i egen produktion eller köpas in. Examensarbetet är ett förarbete till ett underlag för beslut om egenproduktion eller köp. Beslutet kommer att tas inom en snar framtid.För fortsatt utvecklingsarbete är en LEAN-3P pärm framtagen som är ett verktyg i produkt- och processförberedelsen..
Den gråtande journalisten : En studie av publikens syn på subjektiv nyhetsrapportering
The aim of this study is to examine how the public responds to the journalists? use of subjectivity in the reporting of broadcasting news. The investigation is a qualitative study based on nine interviews with respondents in ages of 21 to 25 from different parts of Sweden. After showing five examples of news reporting with a subjective approach, the respondents gave their look on the use of subjectivity. The theoretical frame of the investigation is founded on the theory of framing (de Vreese, 2005; Entman, 1993) and the discussion concerning the terms objectivity and subjectivity (e.g.

Ansvarsområdet omfattar dieselmotorer, transmissioner, axlar samt fordonselektronik. I Eskilstuna produceras axlar och transmissioner till dumpers och hjullastare. För att företaget skall kunna vara konkurrenskraftigt i dagens dynamiska situation är det viktigt att ständigt förbättras och skapa förutsättningar för framtida förändringar. Den hårdnande konkurrensen på marknaden medför att tiden mellan nya produktmodeller minskar vilket medför att behovet ökar att på ett snabbt och kostnadseffektivt sätt ta fram prototyper.
Tidsåtgång för rundvirkesmottagning på Södra Cell Mörrum
This study was made for the round wood transport company MT Transport AB. Time studies were made in order to analyze time consumption on the mill site for timber trucks delivering round wood at the Södra Cell Mörrum mill. The most interesting was to see how much of the time spent at the factory that was waiting time. In three weeks the study was going on and the drivers were clocking it themselves..
Konstruktion och utvärdering av diplexer
The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore it is advantage to have zero at 80 MHz. The reason for this is that a proposed class of hybrid filterbanks with very good quality requires a zero at or close the sampling frequency to work well. The diplexer was made in three versions.
Fallen som föll : en studie av kasusbortfall i ett medeltida brev
There is an old saying, that after Epaminondas nothing was ever the same again. In this thesis I will focus on three questions: "Epaminondas the man." Who was he? "Epaminondas the general." How did he change the technique of warfare that made it possible to beat the Spartans? "Epaminondas, founder of cities and wall-builder." How did he build the walls around the cities he initiated, that made them resist enemy attacks for many years to come?While seeking the answers to yhese questions I will make a contextual analysis to get the historical background to all the phenomina involved..
Tillgång till Open Access: En studie av hur svenska högskole- och universitetsbibliotek tillgängliggör Open Access-tidskrifter i ämnet fysik
The aim of this Master thesis was to examine how libraries at Swedish colleges and universities make Open Access journals in physics available to users. We examined if, where, and how the 50 Open Access journals that are listed in the Directory of Open Access (DOAJ) under the heading Physics (General) were made available to the public at 19 Swedish colleges and universities. We also examined possible patterns regarding qualities in the Open Access journals and to what extent the libraries made them available. For this descriptive statistic was used. The selection of library portals that were included in the study were those Swedish colleges and universities that teach physics.
En pall, en mall : Att yteffektivt och rationellt producera formpressade trämöbler i det lilla snickeriet.
Mitt examensarbete, En pall, en mall, gjordes på Carl Malmsten Furniture Stiudies, Linköpings universitet, under våren 2011. Jag har läst om befintlig teknik inom formpressning och olika tillämpningar av mallar i samband med tillverkning av möbler. Jag ville utveckla ett system som utnyttjar både pressning och fräsning. Detta förslag ska kunna ligga till grund för att mindre snickerier med målsättningen att producera möbler av böjd plywood/faner kan göra det utan stora investeringar i maskiner. Målet var att all bearbetningen på varje möbel är möjlig utan något annat utöver en vanlig överhandsfräs..

Förhandlingslösning som alternativ till fortsatt militär kamp : en studie av två irreguljära parters val
The Swedish Armed Forces tend to ask themselves if it is sufficiently multinational interoperablefor participation in international operations. An equally valid question today should be whether theSwedish Armed Forces are sufficiently nationally / internally interoperable, between their branchesof service, to be able to conduct independent operations based on the joint warfare theory.The lack of ability to joint warfare in the armed forces in general and the Swedish Armed Forcesspecially constitutes the essay´s fundamental problem. By using Codners and Sjöbloms custominteroperability theory, the Swedish Armed Forces documents were analyzed to highlight anyweaknesses related to joint warfare and national interoperability between Ground and Air Forces.The survey shows weaknesses linked to the custom theory and Swedish Armed Forces governingdocuments. The ability of a national interoperability is limited between Ground and Air Forcestoday, mostly because of weaknesses in the Swedish Armed Forces strategic concept which doesnot describe the importance of joint warfare at all levels sufficiently. This leads to deficienciesreflected in doctrines, regulations, technology, techniques and exercises.
Vad vet gymnasieelever om betygskriterierna och kursplanen i Idrott och Hälsa?
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
