RFID i tillverkningsföretag : Fallstudie Hästens Sängar AB
Radio Frequency Identification RFID är en teknologi för att kunna identifiera produkter via radiovågor, detta med hjälp av radiosändare. Denna uppsats intresserar sig för hur RFID kan användas i tillverkningsföretag och om tekniken kan förbättra och förenkla materialflödesprocesserna. RFID är en relativt komplicerad teknik därför har denna uppsats som syfte att ge företag praktiska tips inför en implementering. För att kunna besvara problemformuleringen har Hästens Sängar AB används som praktikfall. Intervjuer har även gjorts med RFID leverantörer och av företag som idag använder RFID, för att få det praktiska perspektivet.RFID används mer och mer i tillverkningsföretag även om utvecklingen har gått långsammare än förväntat.
En retrospektiv epidemiologisk studie om hudproblem på dobermann :
It is a well known fact today that suffering due to skin disorders is one of the most common causes to veterinary calls. For the Doberman breed included in the group of working dogs, the frequency and distribution of the different skinrelated diagnoses that causes visits to the veterinary clinics remains undocumented. The purpose of this study was to evaluate the frequency of skinrelated problems causing veterinary visits of Doberman at four different veterinaryclinics in Sweden retrospectively, and compare these results with dogs in general and three other working dog breeds with the help of information collected from Agria - a Swedish animal insurance company.
The total amount of veterinary calls that were registered at the clinics in question during the time of the study was 2460 visits. From these, 658 visits were due to skinrelated disorders, which amount to 27%. The most frequent cause to skinsuffering was injury caused by trauma, 15,7% of the Dobermans that were included in the study were affected, the second most frequent cause was inflammatory and infectious skin problems with 12,3% followed by neoplastic changes in the skin with 7% of the Dobermans affected.
Järnberikning av mjöl : exemplifierat med Egypten och Iran
The purpose of this study is to give an overview about iron fortification from the view of technique and health. Example of a technical aspect is different iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental iron. In the aspect of health the big question is if iron fortification can improve the health in reducing the prevalence of anemia. The study focuses on flour fortification with iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.
Influence of providing objects to piglets before and after weaning on behaviour and weight gain
Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction.
The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.
Situationer och varumärkeslojalitet : Hur återkommande köp- och konsumtionssituationer är kopplade till konsumenters varumärkeslojalitet
The thesis focuses on the measurement of situational factors affecting brand loyalty in purchases and consumption. A survey is conducted using previously developed scales and 199 respondents. Results show that for the particular product category (ready-to-drink recovery drinks), purchase frequency and the product experience have stronger effects on loyalty than do situational factors such as type of activity and perceived stress. Implications for managers are discussed and suggestions for further research is presented..
Berättelsen om Ann : etik i Stig Larssons roman Nyår
The aim of this study is to examine if Kenneth, a character in the novel Nyår by Stig Larsson, takes his ethical responsibility for one of the characters that appears in one section of the book, Ann. Nyår has often been related to morality. This study shows that Levinas philosophy of ethics is a supplement to the discussion of morality. According to Levinas, a person that acts in a non-moral way still can act in a righteous ethical way. With this starting point, it is possible to be close to the text and to bring out new perspectives on the novel.
Säkerhetsutvärdering av smarta dörrlås utifrån ett kommunikationsperspektiv
Intresset för smarta hem ökar kraftigt. Efterhand som smarta hem-konceptet utvecklats och trådlös kommunikation blivit normen har komplexiteten hos systemen ökat och nya säkerhets- och integritetsproblem uppdagats. Syftet med denna uppsats är att undersöka om någon information kan utvinnas ur kommunikationen hos ett smart dörrlås som finns ute på marknaden i dagsläget. Detta har undersökts i form av experiment genom avlyssning av dörrlåsets kommunikation följt av automatiserad och manuell analys av den insamlade datan. Resultatet av studien visar att avlyssning kan användas för att kategorisera kommunikationen och kartlägga interaktionen med det uppkopplade dörrlåset..
KRAV OCH MÖJLIGHETER FÖR STYRNING AV VATTENFALLS VATTENKRAFTSTATIONER
The secondary control must be part of the production plan, since the capacity will bedeployed in advance, just as the primary control. The activation of the new frequencycontrol should be preformed in Vattenfall's operations centers (DC) to minimizecommunication delay. Vattenfall needs to work towards a more holistic optimizationsystem. The main issue for Vattenfall Generation is not how we produce but ratherwhen, which is done with creation of bids. This is where there is the mostopportunity for improvement.

Detta arbete har utförts hos utvecklingsgruppen inom Gargnäs Elteknik AB. Gruppen har tagit fram ett kommunikationssystem för gruvhissar där man förmedlar data och röst, Cagecom. Min första uppgift blev att sammanställa dokumentationen för alla delprojekt. Jag har gjort en webb-presentation av Cagecom som kommer att ligga på deras hemsida. För att ladda programvara till Cagecom använder man sig av ett dumpprogram.
H?RNERVMOSSA I SANDSJ?BACKA NATURRESERVAT: Analys av h?rnervmossans invasivitet p? ljunghedens vegetationstyper
Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.
P3 Dokumentär: från idé till färdig produktion
Allt fler produktioner till Sveriges Radio (SR) görs idag av externa bolag och radiojournalistyrket präglas av tidsbegränsade anställningar, vikariat och frilans. Som examensarbete i Medie- och kommunikationsvetenskap C ville jag därför ta chansen att undersöka hur processen att sälja in en produktion till SR går till och jag undersökte därför hur man går tillväga när man producerar en dokumentär för Sveriges Radios P3, från idé till färdig produktion. Syftet var att genom mitt eget utvecklingsarbete lära mig hur processen går till och dessutom få dokumentären såld och sänd i P3. Som metod valde jag att följa processen genom att noggrant redovisa mitt eget utvecklingsarbete från idé till färdig produktion då jag själv skrev programförslag till P3 Dokumentär och sedan producerade en dokumentär efter formatets ramar. Jag analyserade min process med hjälp av Norman Faircloughs tredimensionella modell för diskursanalys och mitt mål var att följa de rådande diskurserna för att ha en större chans att få sålt in dokumentären.
Data och metodik för utbytesberäkning - en studie på Medelpads Skogsförvaltning
To manage the industry?s need of wood assortments in a optimal and cost effective way the forest companies need to have knowledge of the actual standing volume and the yield of the planned clear cuts. The mean volume of the trunk is also important since it is important for the contractors prices. Today the total volume are estimated either with Näslund (1940) or Brandels (1990) functions of volumes, and the yield is estimated with Rune Ollas (1980) function for trunks and stands. The purpose of this study has been to answer the following questions: How good is the yield forecast with data collected with currently used methods? How well can the yield forecasts became with data collected according to the instructions? How well can the yield forecast be with data collected according to the instruction and calculated with the program Aptan for theoretical bucking? The study has been initiated and financed by SCA Skog AB.The material consisted of a number of randomly selected objects ready for clear cut.

Lokalisationen av osteochondrosförändringar hos svenska halvblodshästar :
The aetiology of osteochondrosis (OC) is known to be complex and multifactorial. The occurrence of bone fragments in joints and their connection to osteochondral disease are no exception. In the hock and stifle joint of the horse this type of lesion has generally been considered to be of osteochondral origin, while the process behind these fragments in the fetlock joint has been up for discussion.
The objective of this study was to determine the frequency and the localisation of OC in Swedish warmblooded horses. In order to do so all radiographs of stifle, hock and fetlock joints performed on Swedish warmblooded horses during the period of 1992-1999 at Regiondjursjukhuset in Helsingborg were examined and the material was divided into two groups.
Methods for Locating Distinct Features in Fingerprint Images
With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
