Automatisk detektering av akustiska resonansfrekvenser i trästockar
In order to measure the quality of the logs, one can with help of Fast Fourier Transform technique get the signals resonance peaks. With help of these peaks you can see whether the quality of a tree is good or bad. This report contains the work of a where a program has been developed to be able to process a vibration created by an automatic hammer hitting on a log of wood. From the processed signal the program should be able to show both the raw wavesignal and the processed measured data from the resonance peaks. Beyond the raw wavesignal and resonance peaks the program should also be able to control the automatic hammer.
Alkohol på idrottsevenemang : En kvantitativ studie om sambandet mellan vuxnas alkoholkonsumtion på idrottsevenemang och gymnasieungdomars attityd till alkohol
The purpose of this quantitative study was to examine the relation between sporting events, where alcohol is served, and the attitude towards alcohol among adolescents. We conducted a survey with 195 respondents, all of whom was students of Swedish upper secondary school. The respondents were between 15 and 18 years of age. The data were analyzed using theories of attitudes and norms. We also analyzed the data using previous research.
Handdatorsystem vid fältbesök
Syftet med examensarbetet har varit att undersöka möjligheterna för ett system till Skogsvårdsstyrelsen Värmland/Örebro, där uppgifter ska registreras i handdator vid fältbesök och därefter verifieras och slutlagras i Skogsvårdsstyrelsens databaser. Under arbetets gång har olika skogsorganisationer och företag intervjuats för att ta reda på om de har någon lösning som skulle kunna passa för Skogsvårdsstyrelsen. De lösningar som används av andra organisationer/företag har analyserats för att få fram för- och nackdelar med de olika varianterna. Slutprodukten innefattar inte någon prototyp på hur uppgiften skulle lösas utan föreslår olika verktyg som skulle kunna användas. Arbetet har grundats på litteraturstudier om införande av GIS i organisationer samt intervjuer och brevkontakt med personer och företag som arbetar med eller har kunskaper om fältGIS.
Hur riktlinjer påverkar gräsrotsbyråkrater : En kvalitativ studie om biståndshandläggare inom äldreomsorgen
The aim of this study was to examine care managers and how they understand and use their discretion. We used a qualitative method and the data was gathered by semi-structured interviews. We interviewed eight care managers in four different municipalities in southern Sweden. The theoretical approach we used was Michael Lipsky?s theory about street-level bureaucracy.
Detektering av sprickor i vägytor med hjälp av Datorseende
This thesis describes new methods for automatic crack detection in pavements. Cracks in pavements can be used as an early indication for the need of reparation.Automatic crack detection is preferable compared to manual inventory; the repeatability can be better, the inventory can be done at a higher speed and can be done without interruption of the traffic.The automatic and semi-automatic crack detection systems that exist today use Image Analysis methods. There are today powerful methods available in the area of Computer Vision. These methods work in higher dimensions with greater complexity and generate measures of local signal properties, while Image Analyses methods for crack detection use morphological operations on binary images.Methods for digitalizing video data on VHS-cassettes and stitching images from nearby frames have been developed.Four methods for crack detection have been evaluated, and two of them have been used to form a crack detection and classification program implemented in the calculation program Matlab.One image set was used during the implementation and another image set was used for validation. The crack detection system did perform correct detection on 99.2 percent when analysing the images which were used during implementation.
Matteidrott : En fallstudie om laborativ matematik
Examensarbetet behandlar matteidrott, vilket är ämnesövergripande undervisning inom skolämnena matematik och idrott och hälsa. Där idrotten ska ses som medlet för att nå fram till målet som är matematiken. Det vill säga att examensarbetet handlar om laborativ matematik med kroppen som konkretiserande verktyg.Syftet med examensarbetet är att försöka ge ett didaktiskt bidrag genom vilket traditionell matematikundervisning möjligen kan utvecklas. Genom genomförandet av en fallstudie ur ett sociokulturellt perspektiv undersöka om elevers referensbilder i matematikområdet geometri kan utvidgas genom den matematik de genomför inom ämnet idrott och hälsa.Undersökningens data samlades in genom ett tillvägagångssätt som benämns som mixed methods i metodlitteratur, vilket bidrar till studiens två infallsvinklar. En med intervju för insamling av kvalitativ data och en med enkät (matematikdiagnoser) för insamling av kvantitativ data.
Branschfonders risk och avkastning : Hur påverkar konjunkturcykeln?
Background: Funds have become a more popular way for investments. After the financial crisis in 2008 there was some sectors that shown a better results than other depending if the sector was affected by the economic situation or not. Therefore can investments in sector funds be a good way to get a high return, but it also has a high risk.Problem: Has the risk any impact on the return considered funds in sectors that is affected by the economic situation relatively to sectors that isn?t affected by the situation in the economy?Purpose: Determine whether sector funds risk has any impact on the return. Also if there are any differences between sectors depending if they are affected by the economic situation or not.
Att skapa en modell som kalkylunderlag för val av förpackningslösning med tillämpning på två produkter
Arbetets utgångspunkt var att Logosol AB gav oss uppdraget att optimera deras förpackningslösningar ur kostnadssynpunkt. Vi insåg tidigt att det skulle bli omöjligt att genomföra en optimering då relevant information saknades och sannolikt alldeles för tidskrävande att ta fram. Detta ledde till att uppdraget övergick från att handla om en optimeringsansats till att skapa ett kostnadsbaserat kalkylunderlag som tillåter en jämförelse mellan olika förpackningsalternativ. Vi koncentrerade oss på två produkter som båda var representativa för en stor del av företagets produktsortiment. Då förpackningar måste köpas in tänkte vi utvärdera om TCO (Total Cost of Ownership)-ansatsen skulle vara lämplig för ändamålet.
Effekter av sedering med dexmedetomidin och butorfanol på hudreaktivitet vid intradermaltest på friska hundar
The effects of dexmedetomidine and butorphanol sedation on skin reactivity during intradermal testing in healthy dogs were evaluated. The effects of dexmedetomidine and butorphanol were compared to medetomidine, a sedative agent having scientific proof of not interfering with skin test reactivity, in a randomised, double blind, cross over study performed on 8 adult dogs. The dogs were sedated with medetomidine (Domitor vet.®, 0,01 ml kg-1) intravenously, or dexmedetomidine and butorphanol intramuscularly (Dexdomitor vet.®, 0,01 ml kg-1; Dolorex vet., 0,01 ml kg-1) after which they received intradermal injections of positive control solutions (histamine 0,1 mg ml-1, 0,05 mg ml-1, 0,025 mg ml-1), a negative control solution (0,9 % NaCl) and allergen extract (Dermatophagoides farinae, Cladosporium and Artemisia vulgaris). After a wash out period the trial was repeated with a reversed sedation protocol.Skin reactivity (wheal size, induration and erythema) and quality of sedation (immobilization, response to stimuli and injections as well as over all working conditions) were evaluated. The combination of dexmedetomidine and butorphanol provided reliable, good sedation and analgesia without adverse effects.
Kalcium- och fosforsmältbarhet hos växande hästar
In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing
horses were increased with 35 and 25 %, respectively, based on results from a Canadian study
showing that daily endogenous fecal losses of Ca and P were greater than previously
suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true
absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is
assumed to be higher for growing horses because their diets are often supplemented with
inorganic P. Thus, an efficiency of 45 % is used for growing horses as compared to 35 % for
mature horses.

En studie om skillnader i statliga och privata bolags hållbarhetsredovisningar
This study examines differences between private and state-owned companies' sustainability reports for the year 2010. Three state-owned companies and three private companies in three different industries have been examined. An effort has been put to explaining if differences are related to the owner or to the industry. The basis for this is that the state owned companies are required to present a sustainability report according to shareholder demands, while the private owned aren?t obligated to present their sustainability efforts.The study has a qualitative basis, and empirical data have been collected by the authors.
EU - ett medel i kampen mot organiserad brottslighet : En fallstudie av hur EU bekämpar organiserad brottslighet i Italien
?During the past few years cooperation between the EU member states has expanded considerably in areas such as justice and homeland affairs. International cooperation in criminal justice has become more important as borders between EU countries has been lifted and because of this, various criminal groups have also had more opportunities to commit crimes cross borders. The Italian mafia groups in particularly have been operating in almost every country in Europe and have exploited the possibilities offered by the EU. The increase of organized crime in Europe has created a demand for EU to step up their actions against the organized crime.The purpose of this essay is to investigate exactly how the significant EU is has been in battling organized crime in Italy.

Exekutiv funktion vid Dystrofia Myotonika typ
Syftet med denna studie var att, med hjälp av ett neuropsykologiskt testbatteri, undersöka huruvida kognitionen är påverkad gällande uppmärksamhet och exekutiva funktioner hos patienter som lider av multisystemsjukdomen Dystrofia Myotonika typ 1. Syftet var också att, med hjälp av självskattningsskalor, undersöka hur de drabbade själva uppfattade sin situation i detta avseende. Insamlade data från en patientgrupp bestående av 33 individer med konstaterad Dystrofia Myotonika typ 1 jämfördes med data från en kontrollgrupp bestående av 25 friska individer. Resultatet visade att patientgruppen genomgående presterade sämre än kontrollgruppen på de neuropsykologiska testerna. Resultaten på självskattningsformulären gick i linje med detta, vilket tyder på att patientgruppen, generellt, delvis är medveten om sina kognitiva svårigheter.
