  1. 1. Hierarchical Concurrent Systems from a Model-Oriented perspective

    Författare :Daniel Einarson; Data Vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap; Computer science; Datavetenskap;

    Sammanfattning : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. LÄS MER

  2. 2. Learning computer systems in a distributed project course : The what, why, how and where

    Författare :Anders Berglund; Arnold Pears; Shirley Booth; Raymond Lister; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; computer science education; computer science education research; computer networking; computer systems; phenomenography; activity theory; learning; higher education; team collaboration; remote collaboration; Computer science; Datavetenskap; Subject didactics; Ämnesdidaktik; Computer Systems; Datorteknik;

    Sammanfattning : Senior university students taking an internationally distributed project course in computer systems find themselves in a complex learning situation. To understand how they experience computer systems and act in their learning situation, the what, the why, the how and the where of their learning have been studied from the students’ perspective.

  3. 3. Preserving Privacy in Transparency Logging

    Författare :Tobias Pulls; Simone Fischer-Hübner; Sonja Buchegger; Karlstads universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Privacy-enhancing technologies; transparency-enhancing tools; transparency logging; authenticated data structures; Datavetenskap; Computer Science;

    Sammanfattning : The subject of this dissertation is the construction of privacy-enhancing technologies (PETs) for transparency logging, a technology at the intersection of privacy, transparency, and accountability. Transparency logging facilitates the transportation of data from service providers to users of services and is therefore a key enabler for ex-post transparency-enhancing tools (TETs). LÄS MER

  4. 4. Geometric Decompositions and Networks - Approximation Bounds and Algorithms

    Författare :Joachim Gudmundsson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer technology; Systems engineering; kontroll; system; Delaunay triangulation; Computational geometry; TSP with neighborhoods; geometric spanners; covering polygons; Computer science; numerical analysis; systems; control; numerisk analys; Datalogi; algebraisk topologi; algebraic topology; Geometry; Data- och systemvetenskap; Geometri;

    Sammanfattning : In this thesis we focus on four problems in computational geometry: In the first four chapters we consider the problem of covering an arbitrary polygon with simpler polygons, i.e., rectangles. LÄS MER

  5. 5. Expressing emotions through vibration for perception and control

    Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER
