Det här examensarbetet presenterar en evaluering av en Klockkorrigerare av klockpulsbredd. Den består främst av en korrigerare av klockpulsbredd (Duty Cycle Corrector DCC) och även en fördröjningslåst loop (Delayed Locked Loop DLL). Det finns många olika korrigerare av klockpulsbredden designade förut, de två populäraste arkitekturerna då har varit enkel eller dubbel återkopplings loop. Den huvudsakliga skillnaden mellan dem är att enkel återkopplings loop använder sig av en öppen loop medan den dubbla varianten istället har en stängd loop. I det här projektet kommer en ny arkitektur att presenteras.

As a part of Göteborg Energi?s work towards a smarter electric grid, the company has chosen to investigate the possibilities of automation in their middle voltage grid. In Europe, there are example cases where these technologies already are installed which many articles on the CIRED conference 2011 proved. Netcontrol Oy in Finland has, together with Tekla, created an automated SCADA system that Vattenfall in Finland today uses. The grid mainly consists of 10 kV open loop fed city grid and this automation is mainly designed for this type of grid.

This paper deals with the question of with witch tools the Alvastra pile dwelling was built. To reach a result I calculate the curvature on 29 stone axes, 8 double-edged axes and 21 simple-edged axes, used in the middle-neolithic in what today is Sweden. These results are then compared with two jams (the point in the pole where the axes edged stopped and left a mark) on two piles from Alvastra pile dwelling..

Abstract The purpose of this degree project is to examine what impact working with physical objects has on children?s learning process concerning addition. We want to explore what addition strategies can be exercised using the game ?Twice as much?. We have observed children in school year 1.

Som en konsekvens av globaliseringen leder förändrade konkurrensvillkor till allt högre krav på dagens organisationer och kompetensen på dess medarbetare. Dessa förändringar har bland annat lett till att färre människor idag vill bli chefer och privat och offentlig sektor hotas av att lida brist på chefskandidater då allt färre människor säger sig vilja göra de uppoffringar som chefskapet innebär.Män har under årtionden dominerat inom de flesta positioner i arbetslivet. Trots att en lika stor andel kvinnor som män idag arbetar, lever dessa traditioner och könsstrukturer till viss mån kvar i moderna företag.Den största delen av alla nyutexaminerade akademiker är idag kvinnor. Många av dessa är till högre grad än män intresserade av att göra karriär. Trots att företagen väntas lida brist på framtida chefskandidater och trots att de flesta som ändå är villiga och utbildade nog till att bli chefer, är kvinnor, tycks det fortfarande vara något som hindrar företagen att rekrytera dessa till toppchefspositionerna.Denna studie belyser de interna faktorer som hindrar svenska företag att rekrytera fler kvinnliga toppchefer.

The project has been implemented in collaboration with Carl-Johan Lundberg on Deltagruppen Ltd in Jönköping. Problem introduction comes from Carl-Johan's own experience from the hotel sector. The problem that all hotels has is that they sell two products, i e. simple - and double rooms. Persons that travel in companies do not desire always to share bed.Focus in the work is to develop a product that holds together two simple beds and forms double bed, concurrent that it goes that converters to two simple bed without needing to disassemble the product and be done invisible.

Sammandrag Information flödar genom samtidens organisationer och behöver systematiskt kontrolleras. Genom att implementera Enterprise Resource Planning Systems, även kallat ERP-system, kan företag enklare samla upp, strukturera och utnyttja all denna flödande information i ett och samma informationssystem. Majoriteten av alla företag misslyckas dock att fullständigt integrera ERP-systemet med sina vardagliga rutiner. Tidigare forskning tyder på att den utbildning slutanvändarna får och ett kontinuerligt ifrågasättande av organisationens värderingar, även kallat Double-loop learning (DLL), påverkar organisationens möjlighet till en fullständig integration. Genom en kvalitativ flerfallsstudie på olika företag inom detaljhandeln, alla användare av samma ERP-system, har denna studie undersökt vilken roll utbildningsfasen spelar för att DLL ska uppstå vid en ERP-implementation.

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..

Introduction: Reversal of a temporary loop-ileostomy is the final step after a long treatment for rectalcancer, an event that the patient has been looking forward to for a long time. Studies have shown that patients often have a significant impact on the bowel function after reversal of the stoma.Aim: To describe how the patient experienced the first time at home after reversal of a temporary loop-ileostomy due to rectalcancer. Method: Qualitative semi-structured interviews, with 15-20 patients who have undergone reversal of a temporary loop-ileostomy due to rectal cancer, will be conducted. The interviewes will be analysed using qualitative content analysis according to Graneheim & Lundman (2004). The patients will be recruited from the colorectal unit at Sahlgrenska University hospital/Östra and from the surgical unit at Kungälvs hospital.

The aim of this thesis was to investigate how teachers in school and in leisure time center look at informal and formal learning. Informal learning is often associated with leisure-time while formal learning is generally linked to school. My questions also deal with the teachers? view of each other?s activities from a learning perspective and visibility of informal learning. I have made an empirical study with qualitative, semi-structured interviews with three class teachers and three leisure teachers.

In this study we aim to investigate what employees at a callcenter see as prospects, opportunities and barriers of learning within a company. To answer the purpose of this essay, two questions were formulated; "What opportunities for learning does employees experience in the company?" and "How can learning in the workplace improve for the sellers?". First, we present what previous research has highlighted regarding workplace learning and learning within the callcenter industry. Afterwards we present ten semi-structured interviews with leaders and sellers within a telecom company in Stockholm.

Does playing have to hurt? - A quantitative study of ergonomics and double bass playing. This is a paper about ergonomics and double bass playing. I have studied the prevalence of playing-related pain in professional double bass players, teachers and students. This study is based on a questionnaire with 11 questions about double bass playing and pain.

This thesis compares the impact on disk performance in a GNU/Linux  environmentwith three encryption algorithms: AES,  Serpent and Twofish in three different implementations: DM-crypt, Loop-AES and Truecrypt. For all three algorithms a key length of 256 bits is used.The thesis shows that the least performance impact during data encryption, and thus file writing, is reached by using AES or Twofish encryption implemented in DM-crypt or TrueCrypt. The thesis shows that some data operations with a sufficiently low processor utilization barely affects disk performance at all if encrypted using the optimal implementation and algorithm.It is also discovered that the performance impact during data decryption, or file reading, can be minimized by using the most efficient implementation and algorithm. The best results are met with the AES or Twofish cipher, regardless of implementation.An important conclusion that  is  drawn is that it is hard to determine a superior encryption solution for all purposes. However, by reviewing and examining the collected data from all aspects of disk performance the AES implementation in TrueCrypt is, with small marginals, determined to be the most optimal..

The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
