1. 1. Det digitala läsandet : Begrepp, processer och resultat

   Författare :Maria Rasmusson; Lisbeth Åberg-Bengtsson; Ulf Fredriksson; Ulla Damber; Kajsa Hansen Yang; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Reading comprehension; digital reading; education; pedagogy; information- and communication technology; mixed-methods; literacy; structural equation modelling; Programme for International Student Assessment PISA ;

   Sammanfattning : The aim of this doctoral dissertation project has been to investigate and describe the reading comprehension of digital texts related to the reading of traditional texts by gender differences, computer-game playing, and socioeconomic background factors. The dissertation is based on four studies. LÄS MER

3. 2. The Relation Between Digital Technology and Values : Thinking Through Multiple Technologies

   Författare :Leif Sundberg; Katarina L Gidlund; Aron Larsson; Jeremy Rose; Mittuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digitalization; digital government; technique; technics; technology; philosophy of technology; paradigms; megamachines; polytechnics; monotechnics;

   Sammanfattning : This thesis addresses two topics: technology and values. More specifically, the studied technology is an ensemble of digital technologies that is often referred to as “digitalization,” and the values are gathered from empirical material from the Swedish (digital) government.

4. 3. Digital straight line segments and curves

   Författare :Shiva Samieinia; Stockholms universitet; []
   Nyckelord :Digital geometry; digital straight line segments; chord property; Khalimsky-continuous function.;

   Sammanfattning : This thesis consists of two papers:Paper A. Chord properties of digital straight line segments.This paper treats digital straight line segments in two different cases, in the 8-connected plane and in the Khalimsky plane. We investigate them using a new classification, dividing them into a union of horizontal and diagonal segments. LÄS MER

   Sammanfattning : This dissertation explores the early digitalization in Sweden. As host to the first summit on the environment in Stockholm 1972 (UNCHE), as leading procurer of computer equipment as well as initiator to the world's first national Data Act of 1973, Sweden pioneered domains that have since emerged as critical to our age: environmental challenges and digital technology.

7. 5. FPGA based data acquistion and digital pulse processing for PET and SPECT

   Författare :Abdel Kader Bousselham; Christian Bohm; Ulf Bäverstam; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital signal processing; positron emission tomography; single photon computed tomography; field programmable gate arrays; digital signal processors; digital data acquisition; free running clock sampling; Physics; Fysik; Physics; fysik;

   Sammanfattning : The most important aspects of nuclear medicine imaging systems such as Positron Emission Tomography (PET) or Single Photon Emission Computed Tomography (SPECT) are the spatial resolution and the sensitivity (detector efficiency in combination with the geometric efficiency). Considerable efforts have been spent during the last two decades in improving the resolution and the efficiency by developing new detectors. LÄS MER
