  1. 1. Development of a new service-oriented modelling method for information systems analysis and design

    Author : Prima Gustiené; Anders G Nilsson; Sten Carlsson; William Wei Song; Karlstads universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Information systems analysis and design; conceptual modeling; service orientation; semantic integrity; static and dynamic aspects; goal modeling.; Informatics; Informatik; Information Systems; Informatik;

    Abstract : This thesis presents a new modelling method for information systems analysis and design, where the concept of service and the principles of service orientation are used for integrated modelling and reasoning about information systems architectures across organisational and technical systems boundaries. The concept of service enables cohesion of the intersubjective and objective modelling traditions by using a single type of diagram that facilitates detection of semantic inconsistency, incompleteness, ambiguity and discontinuity between the static and dynamic aspects of information systems specifications.

    Abstract : Traffic congestion is increasing in almost all large cities, leading to a number of negative effects such as pollution and delays. However, building new roads is not a feasible solution. Instead, the use of the existing road network has to be optimized, together with a shift towards more sustainable transport modes. READ MORE

  3. 3. Information Systems Actability : Understanding Information Technology as a Tool for Business Action and Communication

    Author : Pär J. Ågerfalk; Göran Goldkuhl; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; information systems; information systems actability; Internet-based information systems; language action perspective; Information technology; Informationsteknologi;

    Abstract : This dissertation is devoted to a perspective from which IT-based information systems are conceived as information technological artefacts intended for business action and communication. The perspective has been made concrete through the concept of information systems actability, which is the main concept under scrutiny. READ MORE

  4. 4. Travelling through time : Students’ interpretation of evolutionary time in dynamic visualizations

    Author : Jörgen Stenlund; Lena Tibell; Konrad Schönborn; Niklas Gericke; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Evolution; visualization; time; learning; threshold; zooming;

    Abstract : Evolutionary knowledge is important to understand and address contemporary challenges such as loss of biodiversity, climate change and antibiotic resistance. An important aspect that is considered to be a threshold concept in teaching and learning about evolution is the time it involves. READ MORE

  5. 5. Enhancing Salient Features in Volumetric Data Using Illumination and Transfer Functions

    Author : Daniel Jönsson; Anders Ynnerman; Kwan-Liu Ma; Linköpings universitet; []
