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.

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.

The student union of Karlstad University is always working for the better for the students, so they can feel safe and that their time at the university is trouble free. To get the students to sign up for a membership, the organization have to inform the students about their work and the benefits that a membership brings. The problem is that the target audience is broadbecause there are all students at Karlstad University that are of different sexes, ages and nationalities, this can cause problems when the information must be adapted to each individual in order to make it interesting. The organizations various work areas have not reached the entire audience and therefore requires an information film in which all the areas can be presented in an attractive way that makes it easy for the audience to absorb the information. A strong trend in the world of information films are the so called infographics.

Digital depth-to-water maps can be produced from a digital elevation model (DEM). Then GIS- based algorithms are used to calculate water flows and the depth-to-water index classes dry, fresh, moist and wet. The purpose of this study was to investigate the possibility to use depth- to-water maps for site adapted planting.The results showed that use of depth-to-water maps for site adapted planting, roughly halved the proportion of improperly planted surfaces from an average of 9 % to 4 %. The variation in the values of proper surface decreased and the result became more even.. In addition, more pine than spruce was incorrectly planted.

The result consists of acombination of these reflections, interviews and a selection of literature relevant tothe subject of new media, the use of social internet communities and social sciencetheories.

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.

Bakgrund: Röntgensjuksköterskor arbetar inom en högteknologisk miljö, där utvecklingen har gått snabbt. När röntgensjuksköterskans arbete övergick till digital arbetsmiljö och dataskärmsarbete, blev kommunikationen mellan radiologer och röntgensjuksköterskor hämmad och arbetsmiljön förändrades. Nya ansvarsområden tillkom och lämnade utrymme för fler självständiga arbetsuppgifter. Syfte: Syftet med detta arbete är att kartlägga vilka för- och nackdelar som den digitala kommunikationen har medfört för röntgensjuksköterskor och radiologer. Metod: En litteraturöversikt genomfördes via systematiska sökningar i databaserna Cinahl, PubMed och Scopus.

Klövsjukdomen digital dermatit hos kor ger upphov till smärta hos djuren samt störningar i produktionen. För att förebygga och behandla klövsjukdomen används olika preparat, däribland CuSO4-lösning.Syftet med studien är att undersöka om och i så fall i vilken omfattning spridande av kopparförorenad gödsel påverkar Cu-halten i jordbruksmark.Studien genomfördes med provtagning av två oberoende jordbruksmarker där ett av områdena gödslas med kopparförorenad gödsel. Resultaten visar att jordbruksmark där förbrukad CuSO4 spridits med stallgödseln ger upphov till en signifikant ökad Cu-halt i markens översta lager, 0-25 cm.  .

GPS (Global Positioning system) and GIS (Geographical information system) has been used for planning and inventory in the forest sector for more than ten years. The last years the development has come to equip harvesters and forwarders with GPS and GIS (GIT). The goal with this study was to reach a basis for decision, how Stora Enso Skog should continue its investment in GPS and GIS in harvesters and forwarders. To reach this basis for decision, possible advantages and benefits, disadvantages and problems in the harvesting process was evaluated. The study was made as an interview study with four harvesting managers and ten machine teams. To secure the quality of the results an interview questionnaire was made before the interviews were done. The results showed that GIT will make the harvesting managers work easier.

The development of software was considered until the beginning of the 1990th as a cathedral like product development in closed companies. This way of development changed in the last decade. Open source software (OSS) development challenged this consideration significantly. OSS is produced in co-operation by skilled people, distributed and used by many moral agents. The result, the software itself, can be studied and modified.

During spring 2001 we have been involved with our bachelor thesis at Doberman Digital Agency, an Internet related webdesign company. We have focused our work on the registration process via digital medias such as the Internet. During our workprocess we have been conducting a number of studies and analyses of workrelated materials. Ethnographical methods such as structured interviews and participant observations were primarily used in our work. We also widely used brainstorming in our designprocess.

En kvalitetsförbättrande metod som senaste åren blivit vanlig inom Hälso- och sjukvård är Lean Healthcare - en verksamhetsfilosof som går ut på att eliminera slöseri och skapa värde för patienterna. I takt med att informationssystem och informationsteknik (IT) har utvecklats har informationsförsörjning fått en allt viktigare roll i vårdprocessen. Tidigare undersökningar visar dock att vårdpersonalen upplever att det finns många brister kopplade till informationssystem och IT. En explorativ fallstudie genomfördes där kvalitativ data samlades in med hjälp av intervjuer, dokumentstudier samt observation. Syftet var att beskriva hur informationsförsörjningen påverkats i ett kliniskt mikrosystem och i en vårdprocess som infört Lean.

Hybrid working solutions have become increasingly common following the outbreak of the Covid-19 pandemic. This new way of working introduces organisational challenges regarding how the culture within an organisation is created and maintained in an environment that combines both a physical and digital presence. This study aims to explore how hybrid work affects an organisation?s ability to develop and maintain its culture, as well as the digital tools and strategies used in the process. This will be studied through an employer?s perspective.

The aim with this master?s thesis is to examine the information practices and information literacies among social workers in the field of the social services and in the work with child welfare investigations. This is in this study related to their ambition to fulfill the requirements of an evidence-based practice. On a theoretical level, the study is based on three theories grounded in the idea of situated learning and of human activities based in a social context. These are the sociocultural theory, the theory of communities of practices and the theory of information practices.
