ADS och Matlab för optimering av pre-distortion av effektförstärkare

This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.

Betydelse av text och uttryckssätt för minnesförmåga och emotion

Hur en text ska utformas och förmedlas om man vill att den ska bevaras i minnet hos mottagaren och vad som väcker emotioner är frågor som den här studien vill söka svar på. Ett bekvämlighetsurval har använts och deltagarna har läst och lyssnat till olika texter. Efter varje text besvarades en enkät. Resultatet visar att utförandet av text och uttryck är beroende på om vi ska läsa eller lyssna till den. Vidare har ett samband mellan upplevd emotion och upplevd minnesförmåga noterats.

Effektiva Lagringsmetoder för Glesa Matriser

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

Kognitiv träning - En litteraturstudie om dess effekt samt eventuella möjligheter inom audiologisk rehabilitering

In recent years cognitive training in order to improve cognitive abilities have becomeincreasingly popular and a lot of research has been conducted within this field. The natural agingprocess has a negative effect on many of our cognitive abilities and this relationship also has a strongconnection with hearing loss. Elderly with hearing loss is therefore a group that could benefit fromcognitive training. Objective: The purpose of this study was to investigate different types of cognitivetraining directed towards Working memory in older adults and to examine the results observedregarding efficacy of this type of training and its transfer effect. Method: A literature reviewconsisting of 17 scientific articles published between 2005-2014.

Modellbaserad prediktiv reglering av en dieselmotor med variabel geometriturbin och återcirkulering av avgaser

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.

Kunskap och organisatoriskt lärande inom Apoteket AB

This paper aims to provide a description of how knowledge can occur in Apoteket AB, anorganization that is operating on the Swedish pharmacy market. The purpose of this paper isalso to describe how the organizational learning occurs in the organization, and how theoutcome of this learning can be stored in the organizational memory. This subject is ofinterest since Apoteket AB experience changes in their external environment in that they nolonger have monopoly to sell pharmaceuticals on the Swedish pharmacy market. Earlierresearch claims that organizations need to develop new knowledge in order to take action, andthis development needs to be supported by the management within the organization.The collection of primary data was done by two qualitative interviews with employees withinthe organization of Apoteket AB.Our conclusions are that knowledge can occur in many forms, such as tacit and explicitknowledge. The vast majority of the knowledge within the organization is the information thatcan be found in the electronic database Aponet within Apoteket AB, and that is useful for theemployees in their daily work, and therefore is known as explicit knowledge.

Myten om Palme : En texttolkning av dokumentären Palme och dess skildring av det sociala minnet efter Olof Palme som norm eller anomali

?The myth of Palme- a textual analysis of the documentary Palme and its description of the social memory of Olof Palme as a norm or anomaly? by Emma Svanström aims to analyze how the directors of the documentary Palme choose to present Olof Palme to the future generations. Also the goal is to find out if their version presents Palme as a person who followed the norms or was divergent.To this purpose the thesis use textual analysis combined with a quantitative method in search of which persons the directors give the right to form the myth of Palme and which keywords they use to do describe him. To view the film as a social memory in the transformation to a myth the thesis use Jan Assmans theory of social memory and to find out if the documentary describes Palme as following the norms or divergent it uses Mary Douglas theory of anomaly.The results show that it is mainly the narrator and Olof Palme that gets to form the myth of him but also his family, friends, fellow employees and other persons that met him or was affected by his actions. Palme is discribed as special, intelligent, interested in social politics and able to act as he saw fit even if it was against the norms.

Navigationshjälpmedel i tredimensionella virtuella miljöer och understödjande av minne

This thesis explores different ways of navigation in virtual environments. It also investigates how virtual environments can support human memory. Tests are done using a self made virtual model of Orkanen Library, Malmö högskolas school library. Among the different navigation tests that were done, a visual guidance in form of a line on the ground leading to the goal is showed superior when navigating a virtual environment but that people prefer legible landmarks instead. Tests were also done which show that a 3D-model of a real location supports context based memory.

Seriell återgivning av två-röstslistor: ord organiseras inte efter röst

AbstractTitle: Serial recall of two-voice lists: Words are not perceptually organized by voice.The present study examined how voice affects the perceptual grouping of words in short-term memory that are auditory presented. Three different voice-lists were used: single-voice, alternating-voice and split-voice. In single-voice lists all words were presented in the same voice. In alternating-voice lists words were presented alternately in a male and a female voice. Finally, in split-voice lists words were presented grouped four and four in a male and a female voice.

Lässvårigheters påverkan på matematikprestationer

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.

LANDALA Stadsdel i skuggan av det f?rg?ngna

In the post-war era many European countries were recovering from the ravages of the bombings of the second world war destroying whole countries. Sweden being neutral was spared the destruction of war but instead we demolished almost as much housing all by ourselves. A social program was modeled to modernize the country and to drag the swedes out of poverty by building one million apartments in just ten years and demolishing the old, dilapidated working-class neighborhoods. The traumatic events of the demolition of large areas of both the central and the outskirts of most Swedish cities is still very much present in the collective memory of people today and the new modernistic districts are still paying the price of that, more than fifty years later. Today these modernistic districts are in need of repair, and they are often homes to groups alienated from society making their reputation even worse.

Nyckeln till arkiven : En kritisk diskursanalytisk studie om interoperabilitet och kollektivt minne

In the democratic process, of discussion and decision making, there is a need of reliable and authentic information. Archives are authentic and reliable information and also provides long term accessibility. But the public archives potential isn´t utilized enough at a societal level. The public archives are organized in a decentralised manner, and there are no common accesspoint at a national level. In the thesis this issue of accessibility and use at a societal level, is discussed in terms of collective memory.

Arkiv, bibliotek, museer: en jämförelse av katalogiseringselement vid tre minnesinstitutioner.

This masters thesis concerns three different types of cataloguing within three different memory institutions museums, archives and libraries. The focus lies on the cataloguing elements which are compared in order to illuminate similarities and differences. The Regional Archive and The National Museum of World Cultures - both in Gothenburg - were chosen and compared to KRS, the Swedish counterpart to the Anglo-American Cataloguing Rules, AACR2, 2: nd ed. The purpose of this comparison is partly to display the elements in order to make students disciplines, but also the staff within archives, libraries and museums to become conscious of each others cataloguing methods in regard to future cooperations within the memory institutions and to see if it is possible to create common cataloguing rules for archives, libraries and museums. The questions asked in this thesis are: 1.
