Läsplatta som hjälpmedel för dyslektiker
Denna uppsats tar upp frågan om en teknisk artefakt, i detta fall läs- och/eller surfplatta, kan ses som en bra lösning för dyslektiker i deras svårigheter med läsningen. Studien har fokus på läs- och surfplattans funktioner som kan vara en möjlighet att hjälpa personer med läsning. Uppsatsens experiment beprövar en redan etablerad metod, läsa och lyssna samtidigt, genom att sätta samman ett antal funktioner och tekniker som finns idag i en enhet. Vi har undersökt om man kan öka läshastigheten och läsförståelsen hos dyslektiker med hjälp av sådan teknik på en läs/surfplatta. Resultatet visar en trend på att metoden fungerar.
Kommunikationskanaler i ett byggprojekt. En studie om vilken inverkan olika kommunikationskanaler har vid förändring av ett arbetssätt.
The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.
Hackelselängden beroende av skördemetod :
The conditions for a good silage process start with good wheather and choice of crop, then choice of harvesting machinery. The shorter and more mechanically treated crop, the better quality of the forage. (Pauly 1994). This study has examined the variations in chopping length depending on harvest method. Precision choppers works with a rotating chopping cylinder, where the crop is cut into pieces.
Expansion av sökfrågor med Svenskt OrdNät som termkälla
The purpose of this Masters thesis is to examine the performance of queries that are expanded by synonyms and hyponyms from Svenskt OrdNät, the Swedish version of the Princeton WordNet. Four different types of queries were constructed: a baseline query S1, the baseline query expanded with synonyms S2, the baseline query expanded with hyponyms S3 and finally the baseline query expanded with the synonyms and hyponyms used in S2 and S3. The terms for expansion were picked by hand. The queries were executed in the Query Performance Analyser QPA, a tool used in IR education and in experimental IR research for analysing and comparing the performance of individual queries. 20 topics from the test collection GP_HDINF were chosen for the experiment.
Modellering av delvis kända objekt med hjälp av bilder
Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.
Avskiljning av uran från dricksvatten med reaktiva filter :
Water is our most important provision and its quality is above all dependent on the
geological conditions in the area from where it is extracted. Due to geological
properties there are certain areas with an elevated risk of high uranium levels in the
ground water, which in turn constitutes a risk for human health. Consumption of water
that contains a high concentration of uranium implies a health risk due to the chemical
characteristics of uranium. Livsmedelsverket (The National Food Administration) and
Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that
precautionary measures should be taken when the uranium concentration in ground
water exceeds 15 micrograms per litre. In particular, drinking water collected from
wells in areas with uranium-rich bedrock may have a harmfully high level of uranium.
One of the wells of the Ärla water purification plant, located near Eskilstuna, Sweden,
contains water that exceeds the guideline of 15 micrograms per litre.
One interesting technique for removing uranium from drinking water is adsorption to
reactive filter materials.
Mångkultur i monotappning : En studie av hur invandrarfrånvaron återspeglas i historieundervisningen på en helsvensk högstadieskola
This paper is about finding a set of unwritten rules pertaining to the teaching of history in an exclusively Swedish college. I want to know if truancy among immigrants has anything to do with SO teachers? choice of content or their teaching methods. Unwritten rules are a complex phenomenon but by applying different perspectives and teaching methods a pattern will emerge. It is possible to discover different influences in the way the teacher chooses their material and work plan.
"Hemma på min gata i stan..." : Tillhörighet, identitetsskapande och fritid bland unga flickor i Gottsunda
This essay investigates the statements of Växjö municipality?s motives for some of its many environmental projects. The aim of the essay is to be theory-testing as to see how a municipality/city which promotes itself as being ?green? motivates its efforts in the environmental area. Växjö city promotes itself as ?The greenest city in Europe?, an award appointed to the city by BBC and other international media.
Belöningssystem inom den kommunala grundskolan - belöningssystem som motivationsfaktor och styrmedel
The transformation within the swedish infrastructure has been a slow process from thebeginning of time. For almost a decade, the traditional form of contracting regardingbuildings and foremost infrastructure has evolved contracting involving the owner to definethe outcome of the product, regardless involvement from the supposed contractor. As forthe swedish market, the traditional design-bid-build (DBB) have been the primary choice ofcontracting. Although changes have been made over time regarding contracting formswithin the road administration, the railway sector has not improved or justified changesregarding choice of contracting, they have conducted same contracting relationshipsbetween them and the contractor.This bachelor thesis, conducted at the Swedish railway administration with supervision ofprofessor Kristian Widén at Lunds University, explores the forces behind the new era ofcontracting within the railway administration. This bachelor thesis focuses mainly oncontracting regarding design-build-operate-main (DBOM), the new contracting formulabetween the owner and the contractor.
IC-påverkan av elektromagnetisk puls
Detta examensarbete undersöker effekter av en elektromagnetisk puls på IC-kretsar.För att kunna utvärdera inverkan har ett testobjekt, innehållande komponenter som skall testas, konstruerats. Detta testobjekt består av batteri, en enkel komponent och last. Ett pulsaggregat och en antenn användes för att generera de elektromagnetiska pulser som testobjektet utsattes för. Resultaten visar att inverkan på de testade komponenterna är möjlig. Inverkan visade sig vara beroende av bl.a.
Aktivt ägande och lönsamhet i svenska företag
Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..
Kolmogorov-Arnold N?tverk, Framtidens AI?
Artificiell intelligens integreras idag i alltfler tekniska system. Trots det, ?r det fortfarande
sv?rt att i praktiken implementera modeller fr?n grunden p? grund av h?ga resurskrav i form
av data och ber?kningskraft. Detta motiverar s?kandet efter effektivare modeller.
I denna artikel unders?ks Kolmogorov Arnold Networks (KANs), en alternativ arkitektur
av neurala n?tverk och j?mf?rs med traditionella arkitekturer som multilayer perceptrons
(MLPs) och faltningsn?tverk.
Svampar associerade med raps : betydelse för uppkomst och grödetablering
Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems.
This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens.
The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.
Korrektionseffekter : stereotyper och viljan att inte framstå som fördomsfull i ett experiment bland studenter
Korrigeringseffekter och stereotyper hänger ihop, för att studera detta användes bilder av ansikten med olika etnicitet och självrapporteringstest skapade av Nosek, Sidanius och Pratto och Dunton och Fazio.Svenska studenter vid Lunds universitet deltog i undersökningen där de delades in två grupper med olika instruktioner, dels falsk information om undersökningens syfte och dels information att vi studerade stereotyper. Detta gjordes för att kunna studera deras korrigeringseffekter. Följaktligen var studien av en experimentell design.Vi fann att korrigeringseffekter fanns hos de båda grupperna vad gällde alla etniska grupper utom vita män, vilka inte hade korrigerats av den grupp som fått felaktig information. Detta visar att korrigering sker för alla minoritetsgrupper till följd av en önskan att inte verka fördomsfull oavsett kontext..
Kommunal demokrati och medborgarinflytande i ett samhälle i förändring
The organisation of the municipalities is based on the principle of representation. It has previously been impossible to give the citizens more influence through direct democracy, but the information technology gives new possibilities and the choice of democracy model might no longer be obvious. Representation can be interpreted in many ways and there is a need for a more distinct definition of the rule that the municipalities shall be governed according to the principle of representation. It should also be further investigated how the new technology can be used to increase the use of direct democracy. The municipalities ought to work to supplement the representation with direct democracy in the form of active discourse with the citizens.
