Lönsamhet av Självscanningssystem

During the last decade, there has been an increase in the use of technology-based self-services within the retail sector. The increase is particularly noticeable within the grocery market. The reason behind the increased use of these systems is partially due to the fact that companies within highly competitive retail markets continually look for ways of decreasing costs while upholding efficiency. The problem is that it is difficult to understand the true economical implications of investments relating to these machines. The purpose of this study is to investigate and contribute with new insights regarding the cost-structures of the stationary self-checkout systems and traditional cashier desks, within the retail grocery market.

Jordbruksdränering, kostnader och genomförande :

Underdrainage is a costly investment but often a necessity to maintain rationalized plant cultivation, one can also see underdrainage as insurance to successful plant cultivation. Late ripening crops, low yield and difficult tillage cultivation are examples on an insufficient drainage. (Kvarnemo 1983) A drained field rise in land price and the scheme of the tiled drains is seen as a value item. The interest for underdrainage among the farmers follows with shifting economic situations within agriculture and has for long time been low. A big part of the Swedish tiled drainage systems is since 1930 and ahead. Many of these tiled drainage systems need to be replaced or complemented. The life length of one tiled drainage system varies with maintenance but can still remain in good function after 75 years with correct management.

Visualisering av Flight Recorder-data i Saab 2000 avionikrigg

The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.

Within SM there are four sub-departments working with activities such as planning, purchasing, receiving inspection, storage and distribution.

Kvinnans rättigheter i rätten : Om våldtäktsdefinitionen i svensk sexualbrottslagstiftning

During the past 10 years Sweden has updated its penal code for sexual crimes twice. Despite this few are convicted for the crime of rape in Sweden. As the majority of perpetrators being male, this is a problem concerning women?s rights to respect for their bodies and personal integrity. A possible explanation, and this study?s point of departure is a potential discrepancy between the intention of the law and the interpretation of the same as the Swedish legal system rests on a foundation of legal positivism.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64

The report comprises two separate parts:part 1:  Temperature needs for district heating in the paint shop for axles in building 210part 2:  Energy and low temperature waste heat solutions in heating and cooling systems for   building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.

Utvärdering och jämförelse av olika fälttester för fotbollsspelare

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Nyttjande av korsningar i mjölkproduktionen

Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.

Styrning av grafisk färgdisplay

This master thesis is a result of the work carried out for Research Electronics at Siljansnäs. The company develops customized electronical systems. Because of the rapidly increasing interest in colour displays there has been a desire within the company to represent information from sensors and electrical systems in a more advanced way.Due to the mentioned reason above we were given the assignment to solve how a colour display using the STN technique works. The technique is used by small displays, the size of QVGA. Our ambition of this diploma work is to develop a fully functionally test prototype to evaluate the LCD (Liquid Crystal Display) and the LCD controller.

Mätning av Mikroläckage i Dentala Implantat

Osseointegrated titanium implants have become a commonly used method in edentulous jaws and today there are success rates in the magnitude of 82 % in the lower jaw and 98 % in the upper. During first year after implantation a fully normal marginal bone loss of 1-2 mm occurs. If the bone loss continues there is a risk of implant failure. High tensions in bone and inflammation caused by bacteria are possible reasons for this problem. It has been shown that a leakage of bacterias occurs between the parts of the implant and there are theories that this has effects on the marginal bone loss. The aim of this thesis has been to increase the knowledge about microbial leakage with help of in vitro tests and virtual simulations.

Från organisationsteori till MTO-analys? : -en fallstudie om fyra chefers arbetssituation

The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.

Utvärdering av metod för applikationsgranskning

Enligt Myndigheten för samhällsskydd och beredskap så är information ?mycket värdefull, ibland till och med livsviktig? (1). Informationssäkerhetsarbete syftar i korthet till att skydda information och för att möjliggöra det krävs det att utifrån de förutsättningar som finns att anpassade skydds- och säkerhetsåtgärder införs för att informationen ska få ett välavvägt, anpassat och kostnadseffektivt skydd i förhållande till dess värde för en organisation eller individ (1).I detta examensarbete har Försvarsmaktens metod för applikationsgranskning utvärderats i syfte att utifrån ett informationssäkerhetsperspektiv se om den är tillämpbar som en säkerhetsåtgärd för andra svenska myndigheter samt ta fram en uppdaterad version av metodiken.Kvantitativa och kvalitativa data har samlats in via enkätundersökning, litteraturstudie samt intervjuer och resultatet visar att applikationsgranskning passar väl in i det övriga informationssäkerhetsarbetet.Denna studie visar att svenska myndigheter har brister i sitt informationssäkerhetsarbete och efterlyser konkreta exempel och metodstöd för att det ska bli bättre. I den här studien visar sig Försvarsmaktens metod för applikationsgranskning vara en lämplig och flexibel grund som kan bidra med detta då den är anpassningsbar utifrån miljö och förutsättningar och en billig säkerhetsåtgärd som går fort att genomföra och klarar sig med små resurser. Metoden ger en god grund till ett fortsatt informationssäkerhetsarbete genom att den metodiskt steg för steg går igenom och granskar en applikation.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.
