Synchronous Latency Insensitive Design in FPGA
A design methodology to mitigate timing problems due to long wire delays is proposed. The timing problems are taking care of at architecture level instead of layout level in this design method so that no change is needed when the whole design goes to backend design. Hence design iterations are avoided by using this design methodology. The proposed design method is based on STARI architecture, and a novel initialization mechanism is proposed in this paper. Low frequency global clock is used to synchronize the communication and PLLs are used to provide high frequency working clocks.
INVERKAN VID VAL AV DRAGSKIVETYP & DRAGSKIVEVINKEL PÅ YT- OCH MATERIALEGENSKAPER AV ETT USKILJNINGSHÄRDBART ROSTFRITT STÅL
Detta projekt har haft till syfte att få en ökad förståelse för materialet och dess egenskaper vid dragning. Det har utförts sex olika försök, vilka har genomförts med två olika ingångsvinklar, 12° och 18°, hos sten, liten nibs samt stor nibs. Försöken har genomförts i produktion där prover har tagits ut för att sedan ha analyserats i labb. Resultat från dragprov, hårdhetsprofil, martensithalts- samt smörjmedelsmängdsmätning har studerats och lett fram till slutsatser.Slutsatserna som dragits visar på att ytan på tråden dragen med ingångsvinkel 12° hade färre defekter än tråd som var dragen med 18°. Defekter som hittades på tråd dragen med stor nibs 18° bestod till stor del av tvärsprickor.
Optimering av antenndesign utifrån experimentella data
During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

Konst Kräver Offer : En analys av Nathalia Edenmonts konstnärskap i ljuset av Pierre Bourdieus kulturteori
Nathalia Edenmont is a controversial and uncompromising photo artist who has caused the whole world to rage over her obscene photographs. In this thesis I have researched Edenmonts artistry with help of the sociologist Pierre Bourdieus field analysis. By using Bourdieus's different field concepts I have researched Edenmonts artistic career by concepts such as habitus, consecration and different principles.The starting point of this research has been that Nathalia Edenmont is in the autonomous artistic field. I give examples of images that have been highly debated and I have collected information of how Edenmont sees her own images and her artistry. In this thesis I show amongst other things an example with Edenmonts photograph of dead rabbits with Elizabethan hair styling, cut up mice that work like finger puppets and children who are bound up in wire.Nathalia Edenmont autonomous artistry is deeply rooted in her background and the environment in which she was raised.
ISO 14001 : En genomgång av SSAB EMEA Oxelösunds miljöledningssystem
Environmental issues is now taking a growing place in society and to ensure that companies meet public expectations and do their part in working towards a sustainable development, environmental management system is said to be an effective tool (Almgren & Brorson, 2009).This case study has examined a company's environmental management system in order to find strengths and weaknesses within the ISO 14001 system. The work was carried out using interviews, document reviews and analyzes in which the three main concepts control the report ; "daily work", "audit" and "environmental aspects".The results shows that the daily work looks different depending on where you are; in the production or at the office. The audit examined all documents related to the environmental management system and the study showed that the biggest strengths was the commitment and waste handling while areas such as environmental goals and management review needed improvement. As a result of the deficiencies identified, suggestions for improvements was proposed. The investigation of the routine of the environmental aspects showed an incomplete routine where the red wire from identification to evaluation was missing.
Skånska trähägnader : en studie i konstruktion och historisk utbredning
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.
Behandlingsformer för övervikt och fetma hos barn och vilka effekter dessa har.
Syftet med denna studie var att beskriva vilka behandlingsformer det finns för överviktiga barn och barn med fetma samt vilka effekter de har på kroppsvikten.Metoden som användes var en litteraturstudie av deskriptiv ansats och sökningen av vetenskapliga artiklar skedde via databaserna PubMed och High Wire Press. Det var 19 stycken studier som svarade mot studiens syfte och frågeställning och inkluderades i studien.Av de behandlingsformer som presenterades i studien hade kirurgi- och läkemedelsbehandling den största effekten på barn med fetma. Studien påvisade att de kombinerade behandlingsformerna inriktade på beteende och kostförändringar tillsammans med fysisk aktivitet och som involverade hela eller delar av familjen hade den största effekten på barn med övervikt. Pågick den kombinerade behandlingen mer är ett år kunde man se en positiv viktutveckling med en minskning av BMI på de barn med övervikt som deltog.De övriga behandlingsformerna som presenteras visar var och en av dem en god effekt under behandlingstiden men avtar efter avslutad behandling.Slutsatsen författaren drar av denna studie var att de barn som behandlas tillsammans med familjen under en längre tid och lär sig hur man förhåller sig till kost och fysisk aktivitet, har störst chans att slippa gå in i vuxenvärlden som överviktig..
ROLL UP! Produkten som förenklar hanteringenav en dragfjäder : Ett examensarbete som startade med en enkel idé och utvecklades till en prototyp
This report presents an independent thesis corresponding 15hp and was carried out on Högskolan in Halmstad during the spring of 2014. The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.
Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Vem skapar nyheterna? : En kvantitativ studie av nyheters ursprung och prioritering i svenska riksmedier
Syftet med undersökningen är att analysera varifrån nyheterna har sitt ursprung och hur återanvändandet av nyheter ser ut i fyra av de största riksmedierna under en arbetsvecka.De fyra medier som ingår i undersökningen är Svenska Dagbladet, Dagens Nyheter, Sveriges Televisions Rapport och Sveriges Radios Ekot. I undersökningen ingår 356 analysenheter och det är en kvantitativ undersökning. För att förstå och analysera resultatet har teorierna gatekeeping, mediernas kommersialisering och nyhetsvärdering använts.Undersökningens resultat visade bland annat att 27 procent av analysenheterna består av köpt eller kopierat material från nyhetsbyråer eller material som är omskrivet från andra medier. Undersökningen visar också att det är stora skillnader mellan olika medietyper. Den största andelen material från nyhetsbyråer kom från tidningarna Dagens Nyheter och Svenska Dagbladet (såväl procentuellt som i absoluta tal).
Styrtransmission för bandfordon
The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.
Brake-by-Wire SystemAn design and development of automotiveprototype
Sigtuna är en av de äldsta städerna i landet. Kyrkan S:t Olof är en av flera medeltida kyrkor i staden. Under hösten 2005 utförde Leica Geosystems en demonstrationsmätning med en laserskanner i S:t Olofs ruin. Från museets håll ville man därefter att hela ruinen skulle mätas upp tredimensionellt för att på ett bättre sätt kunna analysera komplicerade kronologiska händelser och förändringar.Man har tidigare inom vetenskapsgrenen byggnadsarkeologi upplevt problem med att åstadkomma en fullständig bild av en byggnad genom tvådimensionella ritningar. I en tredimensionell avbildning synliggörs rummet på ett mer fullkomligt och verklighetstroget sätt.
Utveckling och konstruktion av dämpare och låssystem för vågkraftverk
The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
Bojkonstruktion
The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.
