Ämnet Idrott och hälsa som grund för ett längre arbetsliv
The purpose of this study is to examine how well the teaching of physical education meets the needs of a future life in the building and construction industry. In order to answer the survey's purpose, we have carried interviews with teachers for the subject Physical education and health as well as with teachers for the Building- and construction program in order to through their experience gain understanding of common health problems in the profession, but also to gain a deeper understanding of the importance of the subject Physical education and health for this profession. We have reported and described previous research and then analyzed it during our processing of collected data material. The result of the interviews showed that the teachers as far as possible are trying to adjust the lessons to suit this practical program. They also indicate several aspects to consider in order to further customize the education for students in the Building- and construction program.
Algoritm för automatiserad generering av metadata
Sveriges Radio sparar sin data i stora arkiv vilket gör det svårt att hitta specifik information. På grund av denna storlek blir uppgiften att hitta specifik information om händelser ett stort problem. För att lösa problemet krävs en mer konsekvent användning av metadata, därför har en undersökning om metadata och nyckelordsgenerering gjorts.Arbetet gick ut på att utveckla en algoritm som automatisk kan generera nyckelord från transkriberade radioprogram. Det ingick också i arbetet att göra en undersökning av tidigare arbeten för att se vilka system och algoritmer som kan användas för att generera nyckelord. Dessutom utvecklades en applikation som generar färdiga nyckelord som förslag till en användare.
Anestesisjuksköterskors upplevelser kring svåra arbetsrelaterade händelser
Healthcare staff working within emergency care must often handle extreme and emotional situations. Most of the certified registered nurse anesthetists (CRNAs) will some time during their professionally active lives confront with events that are difficult to handle and for some these events will lead to more or less serious traumatic distress and in certain cases develop post traumatic stress disorder symptoms. Many studies demonstrate that staff working in similar stress related environment runs larger risk in order to get stress related symptoms. The aim with the study was to describe the experiences around difficult work related events among CRNAs. The study was implemented as a descriptive study with qualitative run-up via a questionnaire with open questions relevant for the study's aim.
Våga Vara Annorlunda?: En uppsats om hur produktengagemang och motivation påverkar inkongruent marknadskommunikation
To be seen is essential. Presently, the marketing of different well-known brands within the same product category is done with little variation. To marketing professionals, this creates an opportunity to market products in an unexpected way. The use of incongruent market communication and by creating a discrepancy between a well-known brand?s advertisement and brand scheme, which is already established in customers? minds, is one way to be different.
"Fenomenalt" eller "De borde kunna mer om datorer" : En undersökning om datorhjälpen på högskolebibliotek
"Outstanding" or "They ought to know more about computers" : A study on computer support at university libraries.The main purpose of this study is to investigate the support computer users are given at university libraries. Further, the aim is to find out if the users thought they received the support that they needed. The study is carried out at two different university libraries. The data is obtained through interviews with the librarians, observations of the daily work at the information counters and questionnaires handled out to the users.The study indicates that variables such as knowledge, time and equipment play a central role in making the computer support successive. To a great extent the computer support is synonymous with information search, but it also deals with word processing and technical support connected with computer errors.
MÖJLIGHETERNA MED CLUSTERED COLUMNSTORE INDEXES & IN-MEMORY OLTP
Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.
Varning! Effekter av varningar i printreklam.: Effekter av varningar i printreklam
The purpose of warning labels used by governments is to decrease consumption. In Sweden, the mandatory warning labels are designed according to statutory guidelines, and not according to research on attention-grabbing graphic elements. This results in a belief that the attention toward the warning labels is poor. An extensive experiment underlies this study, which has the purpose of providing insights to the effects that warnings, warning design, and warning content has on attention, attitudes and behavior in print ads. The study shows that, even though the standard design and content has lost much of its potential to communicate the warning, it gains more attention compared to a warning label with new design and content.
"Nytta vet jag inte om vi har, men vi har roligt i alla fall": En studie av äldres IT-användning
The aim of this Masters thesis is to examine the use of IT, that is the Internet and other applications of personal computers, among seniors 65+. It also deals with issues of access to IT for seniors in public libraries. The theoretical background of the study consists of Rogers "Diffusion of innovations", Hektors categories of information activities, and the Swedish IT-commissions categories of motives and prerequisites for the use of IT. The research questions focus on factors motivating the use of IT, the extent and the purposes of IT use, the consequences and the barriers that IT-users experience, and views on IT in public libraries and IT courses, respectively. Qualitative interviews were carried out with nine senior IT-users.
Pelletering av tallspån : grundläggande studier
Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity.
Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.
"Man är ju inte mer än en människa" : En kvalitativ studie av känslor och emotioner i en handledares arbete med ensamkommande flyktingbarn
The purpose of this paper is to find out the staff's feelings and emotions in a HVBaccommodation where they work with unaccompanied refugee children. A HVBaccommodation is an institution that refugee asylum seekers come to in the beginning of their refugee process. To shed some light on this issue, a hermeneutic perspective has been used in the methodological approach of the work. The material gathered through interviews is collected from six supervisors at the selected accommodation in southern Sweden.The material based on the interviews is grounded in the supervisors' experiences, emotionsand feelings. Our result has been used as a foundation for the analysis of feelings andemotions based on three theoretical approaches: The total Department of Goffman (1973),socialization and the significant other Mead (1934), and the relationships and emotions atwork Hochschild (1983).
Metoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket efter den nya skogsvårdslagen
Detta arbete har undersökt skillnaderna mellan den nuvarande skogsvårdslagen och den föregående. Undersökningen har bestått av två delar, där ena delen är en litteraturstudie av lagarna och den andra är en fältstudie av metoder för att mäta naturhänsynsförändring. Som komplement till fältstudien har en litteraturstudie av undersökningsparametranas naturvårdsnytta. Litteraturstudien av lagarna gick till på följande sätt, inledningen av båda lagarna och hänsynsparagraferna har lästs och jämförts. Fältstudie har gjorts efter metoder som har arbetats fram och sedan testats i fält.
GPGPU-LOD (General Purpose Graphics Processing Unit - Level Of Detail) : Grafikkortsdriven terräng-LOD-algoritm
Dagens grafikkort är uppbyggda av kraftfulla multiprocessorer som gör dom ypperliga för att hantera parallelliserbara problem som skulle ta lång tid att utföra på en vanlig processor, så som exempelvis level-of-detail eller raytracing.Denna rapport presenterar en parallelliserbar level-of-detail algoritm för terränghöjdkartor samt implementerar denna för användning på grafikkort användande Nvidias CUDA API. Algoritmen delar upp den totala höjdkartan i sektioner som ytterligare delas upp i mindre block som beräknas parallellt på grafikkortet. Algoritmen räknar ut vertexpositioner, normaler och texturkoordinater för vardera block och skickar datan till applikationen som skapar vertex och indexbuffertar och renderar sektionerna. Implementationens prestanda och förmåga att reducera trianglar analyseras med två olika sorters culling-metoder; en metod som gallrar trianglar på sektionsnivå och en metod som gallrar på blocknivå.Resultaten visar att det är mycket fördelaktigt att låta grafikkortet hantera level-of-detail beräkningar på detta vis även om minneskopiering över grafikkortsbussen är ett problem, då det tar upp ungefär åttiofem procent av den totala tiden för att hantera en sektion. Beräkningarna i sig tar väldigt lite tid och det finns gott om utrymme för utveckling för att uppnå en så bra fördelningen av trianglar över terrängområdet som möjligt..
Realisering av en modulär skogsmaskin - En skalmodell
Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.
Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Hur påverkas bentiska funktionella födogrupper av kalavverkning? : Effekt på abundans, samt återhämning, av funktionella födogrupper efter kalavverkning kring små vattendrag.
Forestry affects most of the forest-covered land in Sweden. In the landscape, the most common stream type is headwaters, which are important sites for many processes and organisms in both the terrestrial and the aquatic ecosystems. The aim of this study was to investigate how the abundance of benthic invertebrate functional feeding groups in headwater streams develops after clear-cutting and if it also is possible to detect a change in the composition of feeding groups. The study also attempts to determine what factors have an effect on temporal changes in abundance of these groups. For the study, 11 sites in northern Sweden were sampled for benthic invertebrates using a Surber-sampler, and for each site canopy-cover and pH was obtained.
