Sammanfattning: SAAB Communication i Linköping sysslar med konsultverksamhet mot ett flertal nationella och internationella företag inom både den civila och militära sektorn. Fokus ligger på flyget med uppdrag inom telesystem, radiosystem, signaturanpassning, EMC, atmosfärisk påverkan mm. I det sistnämnda ingår även kosmisk strålnings inverkan på elektronik. Den fortsatta miniatyriseringen av elektronik, speciellt minneselektronik leder till ökad känslighet mot den kosmiska partikelstrålningen som ständigt regnar ner på jorden, därför är det extra noga att minnen testas innan de sätts i bruk vid flygburna system. Syftet med detta examensarbete är att konstruera en provplattform som registrerar fel som uppkommer i ett DDR2 SDRAM minne vid påverkan av den ovannämnda strålningen. Detta examensarbete är en vidareutveckling av en provplattform baserad på en FPGA ? lösning.

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Control of a diesel engine equipped with Variable Geometry Turbine (VGT) and Exhaust Gas Recirculation (EGR) requires a multivariable control method. One problem is that the engine system is non-linear. Furthermore there are strong cross-connections between inputs and outputs and the inputs have alsoboundaries. To be able to manage these control problems, MPC has been used that is a multivariable method. The MPC-controller consists of an optimization problem and therefore MPC can find the optimum control signals in an easy way.

During the past two decades a new expression has emerged in Swedish business linguistics: Styrelseproffs (appr. Board Professional). The aim of this paper is to study whether a board member legitimately can be considered a professional. This is investigated through the eyes of the theoretical framework of professionalization. The empirical data is collected through interviews and presents the perspective of people considered to be Board Professionals.

Människan minns händelser och rörelser som hon själv genomfört bättre än de hon fått berättade för sig. Minnet för händelser och rörelser behandlas i det episodiska minnet. Multimodal memory theory är en teori om det episodiska minnet vilket bland annat behandlar förkunskapernas och modaliteternas betydelse för minneskapaciteten. Då människan genomför något används den motoriska modaliteten och då hon får höra något berättas används den verbala modaliteten. Det som har undersökts är om minnet och förståelsen för komplexa och tekniska lösningar påverkas av vilket modalitet som används vid inkodningen.

The aim of this study was to examine if biological early maturing girls and girls that percieved that boys treated them as older than they actually where drank more alcohol, were more delinquent, had more romantic relationships and sexual intercourse. Our data was collected from seven schools in Sweden. Significant relationships where found between early maturation and all four dependent variables. Significant relationships could also bee seen between how girls perceived that boys treated them and alcohol use, romantic relationships and sexual intercourse. For two of our dependent measures we found week interaction effects, for girls biological maturation and there perception of how boys treated them according to there age.

Enligt PISAs undersökning (Skolverket, 20I3) uppvisar svenska elever idag sämre prestationer i läsförståelse och matematik. Många påverkansfaktorer är omdiskuterade men varken lässvårigheter eller matematiksvårigheter har berörts. I relation till detta upprättas en litteraturstudie med syftet att undersöka huruvida lässvårigheter samverkar med matematiksvårigheter och hur det påverkar matematikprestationer. Resultatet av studien visar att lässvårigheter inte alltid påverkar matematiskprestationer. Somliga elever uppvisar svårigheter medan andra inte gör det, dock synliggörs kombinationen läs- och matematiksvårigheter oftare än svårigheterna var för sig.

The fashion market is highly dynamic, and characterized complexity, abstract phenomena and creativity. Further, differences between factors such as gender, countries and social classes pose increasing challenges to fashion companies and researchers active within this area. In light of these facts, the value of creating tools that help companies and professionals active within this industry becomes evident. Much research has been focused on creating a more thorough understanding of its underlying logics and its main drivers from a business perspective, whereas knowledge regarding fashion consumers and what drives their behavior are more limited. Through this study, insights about the Swedish fashion market and its consumers are generated.

In this essay a pilot study on the memory of Swedish Public Service radio news is presented. 30 subjects participated in the study, which was performed during three days, 18 to 20 of November 2013. The material which formed the basis for the study consisted three newscasts of Sweden's most popular radio newscast ?Dagens eko?, which is broadcasted live at 16.45 every day in the Public Service channels SR P1 and SR P4. The subjects listened to the broadcasts each day, and their memory of them was tested the day after each broadcast.The aim of the thesis is to find out which properties of the audience that affect how much ? and what parts ? of a newscast that the audience remember.

A pupil with ADHD is constantly getting new impulses and is unable to focus and remain concentration on their task at school. When the pupil loses concentration he or she can often be loud and thereby disturbing all the other pupils in the classroom. One of the reasons for losing their concentration is that these pupils got poor working memory. A recently study shows that working memory can be improved by playing and practice music.A theory that all people have a multiple intelligence that emerges from learning is a part of this study because school should encourage all children and ensure their individual learning. Multiple intelligences means that each person learns in different ways, for example through the musical intelligence that this essay partly focuses on.

The aim of this study has been to, through a couple of chosen theories, examine in what way Japan as a nation can be said to have dealt with its dark past - concerning their crimes of war just before and during World War II. To do so, I have placed two chosen war crimes, namely the Nanjing Massacre and the matter of the Comfort Women, in the context of remembrance and commemorating of war, through different kinds of aspects. Those aspects are: the textbook conflict, official apologies, ruthless/unnecessary comments, and visits and commemorations at the Yasukuni shrine.I have found during this study that the nation of Japan has not been able to generate a broadly accepted dominant cultural memory of the war. Henceforth a couple of rival cultural memories are competing and becoming an issue of national division rather than national unity. I have come to the knowledge that there are both domestic and international political factors at play, resulting in this division..

While reading in deaf children has been the object of a number of studies, the reading abilitiesof children with mild and moderate hearing impairment and their relation to cognitiveprocessing have not received very much attention. Predictive factors of reading ability inhearing children are well known, with phonological and working memory abilities beingnecessary prerequisites for reading development. Existing studies suggest, however, thatcertain hearing-impaired children achieve a reading level comparable to that of hearingchildren in spite of impaired phonological abilities. In the present study, reading abilities anda range of cognitive processing abilities were measured in a group of hearing-impairedchildren and compared with hearing controls in equivalent school grades. Comparisons weremade at group and school-grade level, and the cognitive profile of hearing-impaired childrenat level with controls (those being within one standard deviation) was discussed.

Natt i marknadstältet is considered as one of Lars Ahlin?s most significant works of fiction. The novel is complex in structure and meaning, containing numerous stories and characters entangled with the main story. One of these stories is the subject of this essay:?Berättelsen om Hedvig och hennes son?.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them.

In this project I have created a design for the delivery rooms of Swedish hospitals with the psychological aspects ofbirthgiving in focus. This is something that I think the delivery rooms lack and so far it has been the midwifes job to,without any tools, give the women in labor the mental support and encouragement they need.My goal was to give the midwifes a tool to work with when it comes to encouragement, something helping themhelping the woman to feel safe and relaxed, strengthened, informed and in control of the situation.I choose to focus on the difficulties measuring the physical work the woman in labour had done and what was leftof the labour. I wanted to visualize the process of the birth, allowing the woman to see and being able to focus onwhere during the labour she is, how far she has left and also being strengthened by the amount of work already managed.Further I wanted to make the woman feel invited to take control over the birth and the room in which she isin labour. I wanted her to be able ? if she wanted ? to make her own settings of the mood in the room, deciding forherself if she wanted a more relaxed environment or perhaps a more energetic.
