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.

Modeling and simulation is growing ever more important in the development of new products. This thesis describes the use of Hopsan for hydraulic modeling and its use in conjunction with Simulink with the intent of using the model in a hardware-in-the-loop setup. A sensor layer has been created in Simulink to emulate all the internal sensors in a modern forklift. The details of using legacy C-code instead of a hardware MCU for a fully simulated environment, software-in-the-loop has been outlined. There are two major routes one can follow implementing software-in-the-loop, exporting the C-functions to CAPL via a export layer or creating an s-function in Simulink.

The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

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..

Begreppet ekonomistyrning innefattar många aktiviteter som i grunden handlar om att uppnå ekonomiska mål. Internprissättning är ett av dessa. När ett företag växer i storlek uppkommer ofta en diskussion om hur organisationen ska decentraliseras och vem som ska fatta beslut. Vanligt idag är att företagen decentraliseras och fler och fler beslut fattas lokalt.1967 gjordes en enkätundersökning som innefattade totalt 235 svenska företag varav bland annat alla börsnoterade. Man ville undersöka vad man i svenska företag vill åstadkomma med sin internavräkning.

Första linjens ledares roll har under de senaste åren blivit mer ansvarskrävande. Vad är då viktigt för ledare i denna position då det kommer till att åstadkomma förändring? Finns det några utmaningar första linjens ledare stöter på? Denna studie syftar till att belysa första linjens ledares upplevelse av att leda en förändringsprocess. Två frågeställningar skapades; ?Vad anser första linjens ledare som viktigt i sitt ledarskap för att kunna åstadkomma förändring?? samt ?Vilka utmaningar möter första linjens ledare i en förändringsprocess??.

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.

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.

   To work and live in the same place where ones employer also is the landlord, can create a situation with many special requirements for the individual. Constrains regarding time, space and impact on social life is likely to appear. Based on theory and empirical research about the Boundaryless work and the Psychological contract the purpose of this report is to examine employees who live and work at the same place. This is done by studying the regulation regarding time and space factors and the psychological contracts in expectations and in violation of the psychological contract and the risks associated with this like Locked-in factors. The study includes interviews with managers and employees (n=9).

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.
