Blogg i förskolan : Hur förskollärare anser att en blogg kan användas för att dokumentera veksamheten och främja föräldrasamverkan
This Bachelor thesis examines the possibility of replacing an outdated, analog video recording system to a digital counterpart. It is key that the video and audio signals remain synchronized, generator locked and time stamped. It is up to nine different video sources and a number of audio sources to be recorded and treated in such a manner which enables synchronized playback. The different video sources do not always follow a universal standard, and differ from format as well as resolution. This thesis aims to compare a number of state of the art commercial of the shelf solutions with proprietary hardware.
ETL-processen : teori kontra praktik
AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.
Bensår Faktorer som påverkar patientens följsamhet till kompressionsbehandling
Bensår är en kronisk sjukdom och ger ofta underbensödem vilket gör att såren blir svårläkta. Den viktigaste behandlingsmetoden för att undvika ödem är kompressionsbandage. Många av de patienter som drabbas av bensår tycker att sårläkningsprocessen är svår att acceptera och de har därför problem med att fullfölja kompressionsbehandlingen. Syftet med studien var att undersöka vilka faktorer som hade betydelse för patientens följsamhet vid kompressionsbehandling av bensår. Arbetet har gjorts som en litteraturstudie av vetenskapliga artiklar.
Visualisering av Flight Recorder-data i Saab 2000 avionikrigg
The main purpose of a Flight Data Recorder (FDR) is to facilitate the investigation of incidents. In order to interpret the data that has been recorded in the FDR the data has to be visualized in some way. This can be done with software on a computer or with hardware that is specific for the model of aircraft that the data originates from.The aim of this project is to visualize data for six parameters from the FDR of Saab 2000 in an avionics rig. The avionics rig resembles the cockpit of Saab 2000 and the displays in it are identical to the ones found in the plane. All six parameters are shown on the same display.Due to safety regulation vital systems in aircraft are doubled, with one system on the left side and one on the right.
How to build a rein tension meter
A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Har intressenterna förtroende för revisorerna?
The purpose of our essay is to investigate the trust in accountants. The method we used to investigate the trust was a survey and a questionnaire was used to collect the data. The data was gathered from three different groups, shareholders, lenders and tax authority. When we analysed the data we found out that the groups trust in accountants were neither strong nor weak. The results can be generalized on all the three groups because the observations were scattered around the means and we used random selection to collect the data.
Prevention av djup ventrombos med graderade kompressionsstrumpor ? Effekt, riktlinjer och rekommendationer : En litteraturstudie
Deep vein thrombosis (DVT) is a serious postoperative complication and nurses should therefore observe symptoms in an early stage and implement preventive provisions, for example use of graduated compression stockings (GCS). The nurse is also responsible for making sure that ordinate GCS tried and used correctly by the patients. The aim of this study was to investigate the latest research regarding the efficacy of GCS in prevention of postoperative DVT and if there are any incorrectness in usage. And assess guidelines and recommendations for the usage of GCS. Method: Literature review.
Datakvalitet : En fallstudie om kvaliteten i SJ:s underhållssystem
SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.
Manuell arytmitolkning och defibrillering prehospitalt för att minska avbrott i bröstkompressioner
Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.
Utveckling och dimensionering av en lastupptagande provningsram
ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.
Energieffektivitet i datahallar
The number of data centers and their capacity is increasing throughout the world. Theenergy used in these data centers and the emissions from the use are increasing at thesame rate. The total use of energy will double from 2008 to 2011 based on the trends indata centers use. Research in this area says that the emissions from data centers willhave surpassed the level of airline traffic in 2020. The index used today to compare howefficient a data center is, called PUE, is lacking some information.
Hantering av viktiga framgångsfaktorer vid utveckling av ett Data Warehouse
Business Intelligence may help organizations in making the right decisions byproviding data for analysis which can be presented to decision makers. DataWarehouse which is a central part of Business Intelligence can be built in severalways but the methods presented by Ralph Kimball and Bill Inmons are considered thetwo main methods. The solution provided by Inmon focuses on integrating the entirebusiness into one large database using relational database development. Kimballhowever proposes dimensional database modeling by creating one or more data martsand integrating these using a data bus. Previous research has shown that the quality ofa Data Warehouse can be measured through critical factors such as data quality andsystem quality.
Utvärdering av riktlinjer för inkorporering av syndikat data i datalager : Praktikfältets syn på tillämpbarhet och nyttoeffekt av Strands riktlinjer för inkorporering av syndikat data i datalager.
Inkorporering av extern data i datalager är problematiskt och problematiken bekräftas av aktuella undersökningar inom området. Detta har medfört att det utvecklats olika former av stöd för att bemöta och analysera problemen som organisationer ställs inför.För organisationer är det i högsta grad viktigt att dess beslutsfattare är välinformerade och klarar av att selektera information från stora mängder data. Det är i dessa sammanhang som en datalagerlösning är en viktig hörnsten för att stödja analys och presentation av data som ursprungligen är lagrad i olika datakällor (både interna och externa). Genom att inkorporera extern data i datalagret uppnår datalagret en betydligt högre potential och således kan även organisationer och framförallt dess beslutsfattare utvinna stora fördelar.Strand (2005) har tagit fram riktlinjer för att stödja inkorporeringsprocessen av extern data i datalager. Dock saknas en utvärdering av riktlinjerna.
