Denna rapport omfattar ett 15 poängs (22,5 högskolepoäng) examensarbete vid Karlstads universitet. Arbetet har utförts på plats hos BAE Systems Bofors i Karlskoga. Företaget ville kunna styra en radiostyrd leksaksstridsvagn med en laserpekare. En kamera ansluten till en digital signalprocessor (DSP) skulle kunna detektera var en laserpunkt befinner sig och styra stridsvagnen mot den.Ett styrgränssnitt mellan DSP:n och leksaksstridsvagnen konstruerades och byggdes med hjälp av en programmerbar logisk krets. Leksaksstridsvagnens interna signalsystem analyserades.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

The aim of this study is to investigate teachers? experiences of working with Writing to Read (WTR), and their perceptions of how pupils develop in reading and writing when they write on computers or similar devices. Another aim is to study teachers? motives for using the WTR method. The material used for analysis is four interviews with teachers who use WTR.

To be able to read and write is necessary to manage well in life. It is important to get a good start in one´s reading and writing development. My purpose in this study was to find out how to teach children to read and write. Obtain knowledge about how to best help children during the early years of reading and writing development, and what is required to teach good reading and writing skills.I wanted to find out how the pedagogues work in the schools, and if they use ant special methods in their teaching. This is something that I, as a future pedagogue didn´t have much knowledge about, which is very important for my future pupils.My research method was qualitative where I interviewed three pedagogues who work whit teaching reading and writing in the early years.

A common form of communication within Facebook is the communication between users via status updates. If you write a status update all your friends have the opportunity to read and to respond to the update. The overall issue of this survey is: how are Facebook users to commu- nicate with status updates?  The survey aims to gain insight and greater understanding of communication patterns and user awareness of social contexts when they write status  updates. The study will act as an attempt to understand a small part of a complex interaction taking place in a social situation.

The dialysis ward at Karolinska University Hospital is a highly pressurized work environment filled with critical treatment situations where patient?s lives can be constantly in danger. Staff have to deal with a myriad of alarms and error codes in response to their patients varying ailments. The workforce at the dialysis ward lack controlled environment training, sufficient to address all of the potential treatment scenarios, with no risk of jeopardizing the patient?s condition.The purpose of this essay is to design and test the efficacy of using an IT based device for dialysis education at Karolinska University Hospital.The main topics this essay intends to address are:? Identification of user scenarios and training fields.? Prioritization of key training areas.? Utilization of IT in effective staff training.? Design of a conceptual prototype.The process focuses on the user and their needs.

In today's society the borders between work and leisure blurs out more and more, and just as we might bring our work home, we might as well take our leisure to work with the help of so called smartphones with constant connection to social networks such as facebook and twitter. But what happens when the small talk around the coffee machine in the workplace gets out in public spaces? Instead of complaining to my closest colleague when my boss is acting like a fool or when my workload sky rocketed, I might now instead update my status on facebook with my complaint. But what am I actually allowed to write about my employer? And has the employer any possibility to act legally in respond to what I write?For the younger generation, who more or less is grown up with these social networks, I think this demarcation can be difficult to draw and understand.In this essay I deal with the issue of whether a principle of law, such as the duty of loyalty might collide with my constitutional right to use freedom of speech against my employer..

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

In this bachelor thesis a complete prototype of an industrial vibration measurement platform has been developed. By measuring a number of variables such as acceleration, temperature and speed conclusions can be drawn on machinery health. The aim is to evaluate hardware and software solutions for a possible future product. Based on a requirement specification a proper hardware design has be developed. The hardware consists of a four-layer PCB with an ARM Cortex-M3 microcontroller and about 250 other components. The PCB was designed, assembled, tested and finally housed in a box.

This essay investigates how the chapters of the interwar and the Second World War have changed in the high school history textbooks during the period from 1944 to 2008. In the study eleven history textbooks have been studied, most quantitatively but also qualitatively. For example the number of pages and rows devoted to different subjects and countries are compared in the books over time. The result of the study shows that there are some big changes over time but in most sections there are also big differences between the books, which make it harder to draw general conclusions. There are a lot more names, pictures and dates in the newer books compared to the older ones, although the number of different names is about the same in all the books.

Workbooks are used and has been used for a long time in teaching context with younger children. Given that children start grade 1 after one year of preschool, I will in my study examine what type of activities that are presented in textbooks used for teaching younger children in pre-school and school grade 1. The purpose of the study is, through a selection of published skill-training materials investigate its pedagogical basic view related to reading and write form of education in pre-school and school grades 1. In line with the aim of the study and to answer the study questions, a qualitative text analysis and pictures analysis was carried out. The result shows that there are more similarities in content than the forms of the textbooks, there are assumptions about language as well as how images should be interpreted in a right way.

The purpose of the present study was to study if the systemic blood pressure in cats significant increases due to stress associated with a visit to a veterinarian clinic. We also wanted to investigate the clinical utility of two different methods for indirect blood pressure measurements in cats by assessing how easy they were to use and how reliable measurements they provided. The methods that were used were oscillometric (Memo Diagnostic) and ultrasound-doppler technique (Minidop). The blood pressure was measured in both clinical environment and home environment. Fifty cats were used in the study, from which measurements were impossible to obtain in one cat.

The purpose of this master thesis is to examine a proposal for basic class 4 in UDC, which has been empty since 1964, and to pick out a negotiable subject for that proposal. The proposal is analysed from a theoretical perspective based on principles created by S. R. Ranganathan. Three principles are used.

This report explains the need to develop a configuration manager that handles transmission equipment which exists in the Swedish Defence telecommunications network. The configuration module will display the configurations and compatibility among the equipment and their software which are all part of the network.Also included in this report are tools, methods and results for the development of a prototype for the configuration manager. The prototype consists fundamentally of a database assisted by a user friendly website.The transmission equipment handles a lot of important transmission of information and is in the hands of a department of SAAB, OFGCA, by orders from the Swedish Defence Materiel Administration (FMV). Within the work included in this order exists a continuous update of both software and hardware which the equipment consists of. Therefore it?s highly important that there is a monitoring of which of the software and hardware is compatible with one another, ensuring that the functions of the system work properly.The consistent updating has resulted in compatibility issues between components and because of this, a need for a configuration manager has arisen..
