Modell för idéutveckling
The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.
Sveriges implementering av EU:s visstidsdirektiv 99/70/EG
This paper aims to study, from a legal dogmatic method, the Swedish legislation on fixed-term work related to the EU directive 99/70/EC1. In particular, the directives demand to prevent abuse of frequent temporary employment.An employer may, in agreement with the Swedish legislation combine different types of temporary employment, to prolong the time in the temporary employment. In this proceeding an employer can avoid employing an employee in a permanent position. For example, an employee can be employed in a probationary period of six months, in a general temporary employment for a maximum of 24 months, and thereafter in a temporary position for a maximum of 24 months before the employment turns into a permanent position. This provided that the employments were made by the same employer, and within five years.
Testprogram till hårdvara på en viktindikator
Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Uttalssvårigheter i svenska som andraspråk hos personer med thailändsks som primärspråk
The intention of this study is to compare difficulties of Swedish pronunciation of five second-language learners with Thai as mother tongue. Thereafter make a comparison with previous research in pronunciation difficulties in people with the same primary language to see if the deviations are similar. I used both recorded material/recordings which I analyzed as well as experiences from pronunciation training that I observed at SFI. The pronunciation difficulties were documented and entered in tables. The recordings consist of 25 Swedish words and a text performed by five informants. In my study, you can distinguish a pattern in my five informants pronunciation difficulties complying with Bannert informants who also have Thai as primary language.
Finns det blockpolitiska skillnader i kommunal skattepolitik?
Med denna uppsats har vi försökt modellera sannolikheten för förändringar i den kommunala skattenivån i svenska kommuner givet deras politiska styre, som är kodade enligt definition av Sveriges Kommuner och Landsting (SKL). Genom att göra det försöker vi få svar på frågan om det finns blockpolitiska skillnader i kommunal skattepolitik. Genom att kombinera SKL:s klassificering av kommunala politiska styren 2002-2006 med 2006-2010 har vi skapat så kallade maktskifteskategorier, som vi sedan använder som kategoriska variabler när vi modellerar sannolikheten för olika förändringar i de kommunala skattenivåerna. För att i viss mån renodla politikens inflytande och skilja det från andra strukturer som kan tänkas påverka skattenivån har vi skapat variabler som vi kallar för kontrollvariabler. Dessa försöker spegla strukturella förutsättningar för den kommunala ekonomin.
Robust algoritm för beröringsfri diametermätning i skördaraggregat
Det första steget i produktionskedjan för trävaror är skördaren vars uppgift är att avverka och sönderdela träd. Sönderdelningen till stockar baseras på sågverkens beställning som innehåller information om önskad längd och diameter. Diametermätning i skördare genomförs idag med berörande teknik som i takt med att kraven för träproduktion ökar kommer vara tvungen att förbättras alternativt bytas ut.I tidigare studier har beröringsfri diametermätning med lasertriangulering genomförts som visar att en ökad mätnoggrannhet går att uppnå, men att robustheten för ett sådant system måste öka för att kunna användas i praktiken. I studierna föreslås förbättring av mätsystemets algoritm som ett naturligt nästa steg för att öka robustheten.I detta examensarbete utvecklas en algoritm som med mätdata från det ovan nämnda systemet strävar efter att göra en robust diametermätning. I algoritmen löses två delproblem där det första är att identifiera bra mätdata genom sökning och eliminering av extremvärden och det andra är att anpassa en trädmodell för att utifrån denna beräkna diametern.
Upprepade ljusstimuli orsakar interferens i mörkeradapterade elektroretinogram hos hund : en utvärdering av några av European College of Veterinary Ophthalmology´s rekommendationer för elektroretinografi på hund
Electroretinography is an examination method where the function of the retina is objectively assessed. In 2002 the European College of Veterinary Ophthalmology (ECVO) published a proposition to a standard on how to perform ERG examinations, to facilitate comparison of results and to make it possible to repeat examinations.
The purpose of this study was to validate parts of the canine ERG protocol suggested by the ECVO. Our principal aim was to study if there is any interference at the recommended stimulus intervals for dark-adapted rod- and combined rod-/cone responses.
The results show that there is an effect on the a- and b-wave amplitudes when different stimulus intervals are employed. When all examined intervals are pooled, there is an increase in the median b-wave to each consecutive dim, white (rod) stimulus in a series of four.
Optimal spelstrategi för yatzy
This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..
Revisorn - granskare eller konsult? : En undersökning av tjänster från en revisor efterrevisionspliktens avskaffande
The question of the mandatory audits be or not be has been investigated thoroughly in recent years. Theresult is that the audit obligation in all likelihood will be voluntary for 96 percent of all of Sweden´slimited companies in the summer of 2010. The new draft law gives the accountant the opportunity towork both as an accountant and consultant. The investigation in this script works with the question"Which services the owner-managed companies, which in future not will be forced to audit, demandfrom an accounting firm in the suspension of the mandatory audit?" This will take the investigation outby a quantitative study through questionnaires distributed to 40 limited companies.
Kalvutdragaren - en hjälpande hand? :
The calf extrator?s function has been studied, through measuring traction and how
this varies in different situations, in comparison with corresponding manual
traction situations. This was done against the background that excessive force at
assisted calvings at dystocia can mean life threatening damages on the calf such as
grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf
extractor has earlier been measured to pull with greater force than the established
maximum force of ?two strong men?.
Översvämningsrisker längs Funboån
Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.
Bredbandig Lobbildning : Bestämning av bredbandiga signalers infallsvinklar med hjälp av en sensor-array
Denna rapport presenterar en metod som möjliggör bestämning av bredbandiga signalers infallsvinklar. Studien är gjord i Matlab där infallande signaler samplades med ett antal sensorer utplacerade ekvidistant på en rätlinje. Den samplade informationen viktades sedan med konstanter framtagna med en konvex optimeringsrutin för att bilda en vinkelberoende utsignal.Rutinerna testades för insignaler med ett få antal frekvenser och gav för alla testade insgnaler en mycket bra bestämmning av infallsvinklen. Studien visar även att det är möjligt att göra systemet mer robust mot störningar i sensorernas positioner genom att ställa kriterier på den konvexa optimerings rutinen..
Tuffa pojkar och gulliga flickor : En kvalitativ studie om pedagogers kommunikation med pojkar och flickor sett ur ett genusperspektiv
Syftet med min studie är att studera hur pedagogerna på förskolan kommunicerar med pojkar och flickor sett ur ett genusperspektiv. För att besvara syftet har jag använt mig av den kvalitativa forskningsmetoden där jag via observationer och intervjuer har undersökt hur kommunikationen mellan pedagogerna och pojkar respektive flickor ser ut. I resultatet framgår det att pedagoger gör skillnad på pojkar och flickor genom sitt språkliga bemötande av könen ? pojkar är tuffa och flickor är gulliga, pojkar får ett robust/vuxet tilltonsfall och flickor ett mjukt/barnsligare, pojkar får fler individuella instruktioner än flickor och pojkar blir benämnda vid namn i större utsträckning än flickor. Flickor tilltalas ofta som en grupp..
CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla
Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.
Emotionell kompetens : om möjligheter till utveckling och betydelse för ett effektivt ledarskap
Purpose of the study was to illustrate how emotional competence can be important for leadership and to explore the possibility of improving emotion perception ability after training. Participants in this study were 40 managers, divided into control and experimental group, within public administration. The participants implemented a data-based emotion perception test, which were done twice at every occasion, with intervention consisting of information or education between test- and retest. The result showed a clear improvement after intervention, in which no difference was found between control and experimental group, which has been discussed on the basis of the likelihood of a training effect occurred between test-retest. Conclusions about emotional competence or leadership ability could not be drawn from the results of the emotion perception test.
