Galna Glassen is a company that has a unique way of selling ice cream in Sweden. The idea is for the costumer to be able to compose their own favorite ice cream, partly by choosing the flavor of ice cream but also by picking the ingredients. The ingredients that can be chosen from are around twenty and can be everything from cookies to candy to berries. When the costumer has chosen their ice cream and ingredients they are mixed together on a cooled granite board.The company was very successful when it was founded in the summer of 2011 and decided to expand to other cities in Sweden. They also wanted to explore the profitability of a mobile sales unit that is intended for festivals and events.The thesis is meant to develop Galna Glassen?s mobile sales unit.
Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen
This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..
Sjuksköterskors upplevelser av att vårda äldre personer som uppvisar beteendemässiga och psykologiska symtom vid demenssjukdom : en intervjustudie
The aim: was to describe and compare a group of experts and critical care nurses' agreement in detecting delirium in intubated, ventilator treated patients with sedation / analgesia, before and after an in house training intervention with the instrument Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).Method: A quasi-experimental study, one group pretest - posttest design. A convenience sample of 17 critical care nurses in a general intensive care unit included. To detect delirium the instrument CAM-ICU was used, 21 paired tests before and 22 after an educational intervention.Main Results: The results showed that after an in house training intervention sensitivity and kappa coefficient improved of the characteristic 1 "acute onset and fluctuating course," an improvement that was significant. In other features, and overall values were signs of numerical improvement and deterioration in sensitivity, specificity and kappa coefficient but no significant change.Conclusion: Implementing a new instrument for detecting delirium in clinical practice requires education and follow-up. A small sample of critical care nurses with varying ability to use the new instrument and the fact that patients' status may change rapidly making it difficult to draw any conclusions from this study.

Kommunikation i operationsmiljö : en litteraturöversikt
AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.
Kan fysisk aktivitet förebygga Alzheimers sjukdom? En litteraturbaserad studie.
Introduction: We are facing an aging population, which means that the incidence of age related diseases, such as Alzheimer's disease, are expected to increase. In the current situation there is no cure for the disease, whereupon it is important to develop preventive strategies. Objective: To examine the association between Alzheimer's disease and physical activity. Method: A systematic literature search was done to identify the current state of knowledge from the year 2006 onwards. The reason for this limitation was that the SBU commissioned a systematic literature review in 2006, where the relationship between physical activity and Alzheimer's disease could not be determined.
Utvärdering av produktionsrapporterad volym för contorta
The background to this study is that the forest company, Holmen, has found large discrepancies between harvested volume and the measured volume at the industry. Factors like bark features, breakage, double tops, bends and stem damages was noted, and all stems were measured manually. Hypothesis testing with the method "random in pairs" were used to examine whether the harvester measured values significantly differed from the manually measured.
The result of a properly calibrated harvester shows in average underestimation of the volume with Skogforsk Pine as a bark function. This means that the harvester isn´t the reason why the volume measured in the industry is lower, the fault is elsewhere. The study also indicates a need for a unique bark function for logepole pine..
Uppföljning av patienter med Transitorisk Ischemisk Attack (TIA)- och minor stroke som medverkat i TIA-skolan på Enköpings lasarett
The purpose of this study was to investigate how patients who had undergone Hallberg's TIA-school at Enköpings Lasarett rate their physical and mental health 18 months after participation. Another purpose was to examine whether they re-diagnosed with a TIA or suffered a stroke. The design of the quantitative study was longitudinal and descriptive. In the study 16 patients participated and to measure their mental and physical health the questionnaire SF36 was used. The results showed that none of the participants suffered a new TIA or stroke since participation in the TIA-school.
Internrevisionens roll - ett svenskt perspektiv
The problem area was identified due to the fact that research within internal audit is fragmented and insufficient, simultaneously to internal audit becoming more common in the public debate. Crises and scandals in companies such as Enron in the US and Skandia in Sweden have resulted in new regulations regarding how companies should be governed. These regulations have been established in Sarbanes Oxley Act (SOX) in the US, and in Sweden the Swedish code for corporate governance will be implemented in 2005. The regulations imply that companies must provide sound internal control and to accomplish that, companies should have an auditing and consulting internal audit function. The Swedish code for corporate governance denotes that companies can decide to comply or explain why the code is not complied.
Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm
One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands.
The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.
Vad gör egentligen besökarna på biblioteket? en användarundersökning på Filipstads Bergslags Bibliotek.
The purpose of this master thesis is to investigate what the users/visitors do at the Filipstads Bergslags Library when they are there. The questions we asked were "What do the visitors do when they are at the library?" and "How do the visitors give priority to the librarys services?" From these two questions we asked a third "How do the visitors view the library and its functions and what function do they see as the most important to them?" The method we used was a user study and we did this at the request of the management at the library. A questionnaire was constructed and handed out in a pilot study. We made some changes in the questionnaire before we started to hand it out at the library.

Automatisk trimning av externa axlar
This master theses deals with different methods for automatic tuning of the existing controller for external axis. Three methods for automatic tuning have been investigated. Two of these are based on the manuell method used today. The third method is based on optimal placement of the dominant poles. Different Sensitivity functions are important for this method.
PWM Effekt Audioförstärkare
The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..
Optimering av gödselgrep för halm
This thesis was performed at SverigeGrepen AB. SverigeGrepen is a company that hasone product on the market; a manure fork that is designed to be used for mucking inshavings or peat. The aim of this thesis was to develop a new manure fork that isadapted to be used in straw.The development started with a pilot study where experience of mucking wascollected to be able to understand what and why certain characteristics are importantfor the function and use of the manure fork.A basic concept was developed where the main function was fulfilled, which meantthat a separation between dung and straw could be performed in a way that wasbeneficial for the user.The work resulted in four concepts of how a manure fork could be used in the strawthat can be designed and constructed. The conclusion that the work gave was that allconcepts met the main requirements required by a manure fork to use in straw.However, concept four provides a good visual impression, while its benefits areassumed to be important qualities..
