We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

In this study I have compared two different development methods of reading and writing. I have done this by interviewing five first grade teachers in elementary schools and it is based on qualitative research interviews. The aim of the study was to immerse myself in which methods these five teachers describe that they have used. They got to describe how they work and how they have tought the students to read and write. I have investigated if the teachers think that the computer is a good tool. The investigation also shows if the teachers believe that the students´ writing skills deteriorate if they can use the keyboard instead. I came to the conclusion that four of the teachers used Arne Trageton´s method (2005) which means that the students learn how to write by using to computer.

Cloud computing is a new buzzword within the IT-industry, and introduces a whole new way of working with IT. The technique delivers web based services, which results in that the user no longer needs to install an application locally on a computer. Since the application no longer needs to run on a local entity, but in a datacenter located on a service provider, the users no longer need any specific hardware more than a computer with an internet connection. Cloud computing also offers IT-infrastructure and development environments as services, these three service types is better known as cloud services. Through the usage of different types of cloud services, the need for maintenance and hardware is significantly reduced.

One important issue faced by companies is to secure their information and resources from intrusions. For accessing a resource almost every system uses the approach of assigning a unique username and a password to all legitimate users. This approach has a major drawback. If an intruder gets the above information then he can become a big threat for the company and its resources. To strengthen the computer security there are several biometric methods for identity verification which are based on the human body?s unique characteristics and behavior including fingerprints, face recognition, retina scan and signatures.

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Medicinering vid sjukdomstillstånd i det främre segmentet av ögat hos häst är ofta tidskrävande och komplicerat för djurägaren. Syftet med studien var att undersöka om ett nytt tekniskt hjälpmedel, en spiral som kallas OphthaCoil, fungerar för långtidsmedicinering hos häst. Två olika designer på spiraler utvärderades. Efter en ögonundersökning placerades en spiral i nedre konjunktivalsäcken och hästen observerades till dess spiralen trillade ur. Resultaten visar att ingen av de använda designerna låg kvar tillräckligt länge för att kunna användas för en längre tids behandling.

This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.

To automate software testing is an investment, and that makes it important to have good knowledge about automation before an implementation is made. In this master thesis a study about automated testing is carried out. The study also includes a closer look at the testing tool TestComplete. TestComplete is one out of many tools on the market that is developed for automated GUI testing and the goal is to get a picture of how well the tool can adjust to CC Systems own applications. Studies show that it is hard to write lasting test scripts.

According to the Läroplan för förskolan, Lpfö 98, are pre-schools suppose to introduce the written language and embrace childrens curiosity about the ability to communicate with the written language. The purpose with this research is therefor to study the attitudes of pre-school teachers towards three- to five years olds writing and also to shred some light over which role teachers and other adults have when children learn to write. The earlier research contains different theories about how children in pre-schools conquer the written language and the teachers role in this process. Teachers attitudes towards and thoughts about childrens early writing could be made visible through interviews with teachers who all currently work at pre-schools. The results indicate that pre-school teachers have different attitudes towards childrens early attempts to write.

Since none of W.A Mozart's own cadenzas for his Violin Concerto no. 4 in D major have been preserved, and there is only one existing standard cadenza by Joseph Joachim, I have chosen to write my own cadenza, but in the end I decided to write three cadenzas. As a background to my thesis I analyzed and studied the different motives in the first movement, as well as four cadenzas from different eras. I made a comparison of these four cadenzas, looking at how the composers have used the different themes and motives from the concerto. I have also explained the meaning and purpose of the term cadenza.

This project aims to obtain a deeper understanding of what it is like to be young today, and of how young people experience their lives. Identifying and uncovering the process of meaning constitution concerning young people's thoughts and feelings within each subjective individual, and their visions about the future as well as how they experience relations to other people in their surrounding, was achieved with a phenomenological approach. The participants were asked to write a self-report in answer to a carefully formulated question.The received reports were analysed according to the method of Meaning Constitution Analysis and Sphinx Lexica. The result showed that young people's lives are both complex and unique. They rather write about friends than family and write less about the future than we first assumed.

The essay is a discourse analysis of the media's attitudes toward computing. The aim is to compare what the media is really saying about the usage of tablets, computers and compare it to what the research is saying. In addition, it examines what the media says about socialization. We analyze the newspapers Dagens Nyheter and Expressen and will first compare these two together and see what attitudes that emerge, and then seek similarities and differences with the previous research and theories including socialization learning, attitudes and consumption. Conclusions we can draw is that Expressen has a more negative attitude towards the use of computers while the Dagens Nyheter has a more positive attitude, but is also more objective to what they write about.
