Framtagande av ny höjdmätningsmetod till försvarets antennhiss 861

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

Turkiet - inte europeiskt nog för gemenskapen?

The Turkish accession to the European Union has been the most extended one that the Unionhas been dealing with so far. Turkey is now accepted as a candidate country but it is still in aproblematic situation. Most of the EU?s member states do not share the Union?s belief thatTurkey should become a full member of the Union, if they should even become a member atall. Europeanization constitutes a ground in this essay, and the ?top-down? perspective withinthis process can give an explanation to why most EU member states have such a hesitanceagainst Turkey..

Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

UTV?RDERING AV APPLICERINGSTEKNIKER MED LASCAUX 303 HV Adhesivet Lascaux 303 HV anpassningsbarhet vid strukturella ?tg?rder p? m?leri p? duk

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

Saklig grund för uppsägning i samband med samarbetssvårigheter

Abstract Co-operation difficulties in the work place can be a problem serious enough. Co-operation difficulties can occur between employee and employer, as well as employees among themselves. Irrespective of between which individuals the co-operation difficulties occur, it will have negative consequences. These can consist of, for example that individuals might suffer mentally, inproductivity and also an unwished economic disadvantage for the employer. From the employers? side it is pointed out that it is important with employees who are possible to co-operate with in a satisfactory way.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Funktionsutveckling av ett UGV operatörsgränssnitt

Examensarbetet syftar till att konstruera operatörsgränssnittet till en UGV (eng Unmanned Ground Vehicle) för mobil rekognosering i tätbebyggt område. Operatörsgränssnittet består av både mjuk- och hårdvara. Till operatörsgränssnittet har ett grafiskt användargränssnitt utvecklats där tonvikten legat på användbarhet med funktionalitet för positionering med geografisk presentation och sensorpresentation. Förutom en presentationsenhet för sensorinteraktion och manövrering av farkost ingår en sändtagarenhet för kommunikation mellan operatör och farkost. Två uppsättningar av systemet levererades till försvarsmakten för användning vid metodförsöksstudier..

En jämförande studie mellan röntgenteknik och mikrovågsteknik för mammografiscreening

Många liv räddas idag då mammografiscreeningen som erbjuds symtomfria kvinnor tillhörande riskgrupper för bröstcancer, gör att cancer kan upptäckas på ett tidigt stadium. Screeningen utförs med röntgen, vilket är den metod som anses mest lämplig. Metoden är förhållandevis snabb och billig, men den har några nackdelar. Den kan vara ospecifik då man med denna metod avbildar skillnad i densitet mellan tumör och frisk vävnad, och ibland är denna skillnad så liten att det är svårt att detektera på bild. Bröst med högt innehåll av körtelvävnad försvårar även detektionen ytterligare.

Hur gymnasieelever med Asperger syndrom upplever Aspergerstudio och skolgång

This is a work about the relationship between cult houses and halls. In my essay I will go through four different places were cult houses and halls both exist. I will look at the findings and the landscapes were the settlements are located in. The places I have chosen are Lunda in Södermanland, Slöinge in Halland, Uppåkra in western Skåne and Järrestad in southeast Skåne. Because of that the cult houses and halls are occurring during the late Iron Age, it is during this time period that I will work in.

Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud

ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using phone interviews.

Avvikelser från Sjövägsreglerna som kan leda till kollision

Att kollidera är en av riskerna som föreligger då ett fartyg framförs till sjöss trots att det finns internationella regelverk, så som Sjövägsreglerna, enbart utformade för att förhindra detta. I denna kvantitativa litteraturstudie har det undersökts vilka avvikelser från Sjövägsreglerna som bidragit till kollision samt hur regelavvikelserna skiljer sig utifrån fartygstyp, tid på dygnet, sikt och bryggbemanning. Haverirapporter utarbetade från två haverikommissioner har undersökts och utifrån haverikommissionernas egna slutsatser om orsak till kollision har författarna sedan identifierat vilka Sjövägsregler fartygen avvikit från vid kollisionen. Två haverikommissioner valdes för att kunna jämföra om det finns skillnader i resultatet i deras utredningar. I en majoritet av kollisionerna hade fartygen avvikit från någon eller några av Sjövägsreglerna.
