1. 1. Exploring Impacts of Secondary Information Use on Individual Privacy

   Författare :Ali Padyab; Anna Ståhlbröst; Magnus Bergquist; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information systems; Informationssystem;

   Sammanfattning : Information collected from individuals via online social networks and Internet of things devices can be used by institutions and service providers for different business purposes to tailor and customize their services, which is defined as secondary use of information. Although the literature on secondary use is well developed, prior studies have largely focused on direct use of information such as those instances of information use that do not stem from data mining.

3. 2. Adoption av elektronisk handel : Innehåll, kontext, process och samspelet mellan dessa

   Författare :Monika Magnusson; Anders G. Nilsson; Péter Révay; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adoption ”adoption” ; e-commerce “elektronisk handel” ; SME ”små och medelstora företag” ; conceptual framework ”konceptuellt ramverk” ; content ”innehåll” ; context ”kontext” ; process ”process” .; Informatics and systems science; Informatik och systemvetenskap; Information Systems; Informatik;

   Sammanfattning : E-commerce is far more common in large firms than in small and medium-sized enterprises (SMEs). As a result SMEs risk competitive disadvantages. A growing body of research has attended to this problem but few studies examine the adoption of e-commerce from a broader contextual perspective. LÄS MER

4. 3. Image segmentation using snakes and stochastic watershed : with applications to microscopy images of biological tissue

   Författare :Bettina Selig; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The purpose of computerized image analysis is to extract meaningful information from digital images. To be able to find interesting regions or objects in the image, first, the image needs to be segmented. This thesis concentrates on two concepts that are used for image segmentation: the snake and the stochastic watershed. LÄS MER
