The Swedish Armed Force has a need to streamline the preparation of an exercise in tactical training for soldiers because the preparation of an exercise is currently laborious and time consuming when commanders manually share files to each computer that will be included in the exercise. The degree project was to create a file sharing program within the internal network of the Defence Forces? international centre (Swedint). The program is used by the training management to effectively start up an exercise where soldiers train tactical training in a simulated combat environment. The training management use this program to upload files to a server which notifies all the computers on the network to download these files.

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project.

 In today?s society teachers will face students of foreign origin. It is up to the teachers to help these students gain the knowledge they need to flourish in society. Despite the fact that mathematics is a universal topic with high status in many countries, studies have shown that mathematics is a subject where a large proportion of foreign students fails. The purpose of this study was to see wherein the problem lies and describe teachers' perceptions of the barriers and the opportunities in mathematics for students with Swedish as a second language.

Today electronics becomes more and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a big gap between the degrees of automization for the two parts and makes the analog parts the bottleneck in electronics develop. Research is ongoing at Electronics systems group at Linköping University target the increase of design automization for analog circuits. An optimizationbased approach for device sizing is developed and for this a good optimization method is needed which can find good solutions and meet the specification parameters.

This report intends to analyze the difference between the original rules and a modification of the rules for the Scandinavian version of the world famous dice game yatzy (yahtzee). Several works are made previously existing strategies for yatzy and Yahtzee.The study was conducted using the optimal strategy calculated and implemented in the programming language Java. The execution of the application to create the file containing the optimal strategy was running on leased powerful servers from Amazon and took just over six hours each.A simulated player played 100,000 games based on the strategy, to obtain data which then was used to plot graphs and analyze the expected score and its standard deviation. The expected value (mean) and standard deviation of the score for the possibility of three or four throws were 233.00 ± 44.82 and 280.07 ± 41.25.In view of the results drawn the expected conclusion that the four possible throws provides increased probability of getting a high score, unlike the case where the player may only be able to throw the dice three times. The fact that the variance is lower in the case of four throw session is equivalent to that the likelihood to get close to the expected value increases..

We are working on the development and design of an approach to agents that can reason, react to the environment and are able to update their own knowledge as a result of new incoming information. In the resulting framework, rational, reactive agents can dynamically change their own knowledge bases as well as their own goals. An agent can make observations, learn new facts and new rules from the environment, and then update its knowledge accordingly. The knowledge base of an agent and its updating mechanism has been implemented in Logic Programming. The agent?s framework is implemented in Java.

The aim is to find out how teachers apply the knowledge they get from mathematics pilots in preschool and from mathematics developer in the municipality, as well as how they work further towards the children with mathematics.The study is based on qualitative interviews with two teachers, one mathematic pilot and one mathematic developer. I used the semi-structured interview questions.The results show that teachers believe that mathematics pilots will inspire the teachers in their work with mathematics in preschool. One of the teachers who were interviewed said:?Mathematics pilots should be those that have the strongest glasses and coming up with new ideas and they push the rest of the teachers in their work with mathematics in relation to children in preschool?.The teachers use the correct terms for mathematical concepts with the children. They also stressed how important it is to point out to the kids that it is mathematics that they are doing.The conclusion of the study is that the teachers agree that it is their approach towards the children that is important and how they can lead the children?s interest of mathematics forward.

Vacation 2.0 är ett ledighetsansökningssystem utvecklat hos CGI i Linköping för deras Linköping- och Norrköpingskontor. Med Vacation 2.0 kan anställda boka in kommande semester, föräldraledighet samt jour. Vacation 2.0 ger HR-avdelningen en översikt över tillgänglig personal genom en sammanställning av alla arbetsgruppers ledighetsansökningar. Systemet underhålls av en administratör som har behörighet att administrera arbetsgrupper och ändra anställdas existerande ledighetsansökningar. De anställda som är ansvariga för en grupp eller är anställd på HR-avdelningen kan ges behörigheten av systemadministratören.Kraven för systemet togs fram genom intervjuer med anställda som vi sedan utvärderade.

The purpose of this study is to examine the importance of a working laboratory in mathematics education, how it influences students? learning and the confidence the teacher has in the laboratory component. Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

Det finns flera fördelar med robotiserad bågsvetsning jämfört med manuell bågsvetsning. När det gäller produktivitet och repeterbarhet är robot överlägsen människa, vilket gör att produkterna håller jämnare kvalitet. I slutet av 80-talet började offline-programmering att tillämpas. Att programmera en robot offline innebär att utföra programmeringen med dator utan direkt tillgång till roboten. Genom simulering visualiseras ett robotprogram i en grafisk modell av den fysiska robotcellen utan att den fysiska roboten behöver tas ur produktion.

Syftet med denna studie var att undersöka hur gymnasieelever översätter mellan tre matematiska språkformer (symbolspråk, matematiskt språk och vardags-språk). Studien använde ett slags test, en kunskapsdiagnos, för att undersöka detta. Gymnasieelever från samma program i tre olika årskurser fick möjlighet att delta i studien. Diagnosen var uppdelad i tre översättningsområden: från matematiskt språk till symbolspråk, från symbolspråk till matematiskt språk och till sist från symbolspråk till vardagsspråk. Resultatet visar att gymnasieeleverna, oavsett årskurs, har problem med översättningarna.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

Att skriva enhetstester är en viktig del i nya populära systemutvecklingsmetoder som extreme programming. Med testdriven utveckling skriver man testerna innan den källkod som skall testas. Ett vanligt problem med dessa tester är att de blir beroende av delar i systemet som inte är intressant för själva testen. Mock objekt är en teknik som gör det enkelt att isolera tester från allt som inte är relaterat till det som skall testas.Det finns två sätt att se på mock objekt. Den traditionella synen är att mock objekt skall användas som ett verktyg vid isolering av externa system.
