The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage of input distributions that are dominated by smaller-amplitude signals e.g. Audio, Voice and Image-sensor signals. A Single-bit feedback topology is used with a multi-bit quantizer in the modulator.

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Internal working models of attachment are claimed to be unconscious structures operating outside the conscious awareness. Existing measures of attachment are almost exclusively explicit, either self-reports or interviews and it is questionable whether these instruments are able to tap into unconscious attachment attitudes. The main purpose of the present study is to develop Implicit Association Test (IAT) tools for assessing adult attachment and to examine their construct validity. Two sets of implicit attachment measures, based on the two-dimensional attachment model (Bartholomew & Horowitz, 1991), were developed. Convergent validity was assessed by examining (1) the relationship between implicit model of self and implicit self-esteem and (2) the relationship between the implicit model of other and implicit sociability.

Detta projekt har haft som syfte att producera och grafiskt formge det kommande numret av tidskriftsapplikationen Scandinavian Architectural Review för förlaget It Is Media Svenska AB i Stockholm. Skapandet har utgått från applikationens tidigare grafiska profil och har ämnat att följa tidigare utseende och funktioner utan nya tillägg. Hela produktionen har skapats genom Adobe InDesigns tilläggstjänst Adobe Digital Publishing Suite. Efter att produktionen färdigställts har en analys gjorts av den färdiga applikationen enligt en heuristisk utvärdering ur ett människa-datorinteraktionsperspektiv, till vilken David Benyons tolv designprinciper har  tillämpats. Till stöd i analysarbetet har ett aktivitetsdiagram skapats för att ge en god överblick över hela tidskriftens disposition.

In this final thesis two simulation models have been integrated. The simulation models are models of JAS 39 Gripen?s fuel system, software and hardware. The time consuming and costly work to develop software has made the department of fuel system to build two models in Xmath/Systembuild. The software model also simplifies the comprehension of how the software in the control computer of the fuel system works.

This report brings up the question - ?Is BIM profitable when planning a single-family home??.The methodology for finding the answer to this question is firstly to state the definitions of BIMand the company that is projecting by using the BIM-model. The answer is then obtained byanalyses of the factors of profitability with respect to: time, opportunity of revision, problemvisualization, preference adjustments and energy. A BIM-model has been made simultaneously asthe writing has proceeded to get a perception of how a BIM-model really matters for the analysis.The analysis shows that the answer for the question depends on further factors. The factors thatare mostly discussed are the company?s intentions and the complexity of the house.

This Masters Degree thesis aims at giving an answer to what underlying ideologies are at work in digitizing our cultural heritage. Other questions to be answered are who are benefiting from a digitized cultural heritage and who are not, and what different opinions about digitizing our cultural heritage can be identified. Two studies are made in this thesis, one of Swedish political documents that concern digitizing our cultural heritage, libraries, museums and archives, and the other one is a study of documentation of three Swedish digitizing projects. In the first study three different, but closely associated ideologies are identified, namely a preserving, b giving access and c a mixture of both, and these are shown in a model. In the second study this model is then used to identify the ideologies of one project from each sector of the so called ABM-sector Archives, Libraries and Museums.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Entrepreneurial failure is probably a subject that is not well understood. This might have to do with the methodological difficulties of screening out failed entrepreneurs. In this thesis a tool is developed for analyzing supposed entrepreneurial failure. In this model entrepreneurs are surrounded by different stake holders. By using the failure deconstruction model to analyze my own entrepreneurial effort I find that it has neither been a successful project nor a disastrous one.

The availability of Digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.

This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.

Idag finns som alltid behovet att distribuera media. Allt eftersom prestandan för överföring av information i dator-nätverk har ökat har detta blivit möjligt genom streaming, strömmande media. Detta innebär att klienten inte behöver ladda ner hela materialet för att kunna se eller lyssna på det. Allt eftersom kravet på kvalitén av materialet ökar blir kraven på nätverket högre. Precisallt Media AB är ett företagsom sysslar med digital skyltning.

In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.

Swedish: Det här kandidatarbetet undersöker om karaktärer med icke-normativ sexualitet finns representerade i digitala spel och hur dessa framställs. Arbetet har även fokus på de reaktioner samhället har visat i samband med att spel som behandlar ämnet icke-normativ sexualitet kommit ut på marknaden. Syftet är att uppmärksamma och ge insikt om icke-normativ sexualitet som ämne och hur diskussionen av detta kan leda till en utveckling inom spelmediet. Informationen som användes för att undersöka ämnet och dess reaktioner finns sammanställt under ett forskningsmomentet, vilket sedan utvecklas till flera noveller. Dessa noveller har sedan användes i en undersökning som genomfördes av 11 stycken deltagare.
