1. 1. Harnessing Handheld Computing - Framework, Toolkit and Design Propositions

   Författare :Bo Andersson; Sven Carlsson; Institutionen för informatik; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mobile Computing; Design Science; Digital Ranger; Handheld Computing; Informatics; Informatik; System Development; Handheld Information Systems; Accentuated Factor Framework; Mobile Computing;

   Sammanfattning : The rapid development of handheld technologies such as smartphones and personal digital assistants in recent years has created opportunities for the mobile workforce to take advantage of computerised information systems. To apprehend and harness the opportunities of computerised information systems implemented on handheld devices it is crucial to fully understand the user group and the handheld technology. LÄS MER

   Sammanfattning : Background: Heart Failure is a serious condition with consequences not only for the individual patient but also for the society with a 5-year mortality rate of 45-60%, and a substantial economic burden. The estimated prevalence in Sweden is 2.2% and the age adjusted prevalence increases with higher age. LÄS MER

4. 3. Wideband Active and Passive Antenna Solutions for Handheld Terminals

   Författare :Peter Lindberg; Anders Rydberg; Anders Pers; Nicholas Buris; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; active antennas; impedance matching; dipole antennas; baluns; slot antennas; microstrip antennas; mobile antennas; multifrequency antennas; antenna proximity factors; receiving antennas; ferrite devices; Teknisk fysik;

   Sammanfattning : This thesis presents solutions and studies related to the design of wideband antennas for wireless handheld terminal applications. A method of electrically shortening the terminal chassis length to obtain resonance at high frequencies has been proposed and evaluated, thereby increasing the antennas impedance bandwidth. LÄS MER

5. 4. Mobile Knowledge

   Författare :Henrik Fagrell; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile CSCW; Knowledge management; Organisational memory; Ethnography; Empirically informed systems design; Handheld devices;

   Sammanfattning : Both the issues of "knowledge management" and "mobility" have received much attention recently. The interest in these issues is often motivated by the fact that work, in many organisations, has become "knowledge intensive" and "mobile". However, so far these issues have been explored separately. LÄS MER

7. 5. Mobile Newsmaking

   Författare :Kerstin Forsberg; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; Mobile CSCW; Journalism; Ethnography; Empirically informed systems design; Handheld devices;

   Sammanfattning : The research reported in this thesis concerns the design of new and innovative IT support for mobile news journalism. News journalists often have to report events on topics that they do not know very well and with little time for preparation. News reporting is often conducted in the field, away from the stationary IT support. LÄS MER
