    Abstract : Medical imaging is an important part of the clinical workflow. With the increasing amount and complexity of image data comes the need for automatic (or semi-automatic) analysis methods which aid the physician in the exploration of the data. READ MORE

  3. 3. Information Worker Productivity Enabled by IT System Usage : A Complementary-Based Approach

    Author : Natallia Pashkevich; Thomas Hartman; Darek M. Haftor; Stavros A. Zenios; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Complementarity; Individual level; Information worker; IT use; IT-enabled productivity; Business Administration; företagsekonomi;

    Abstract : Assessing the conditions of productivity of individual workers who process information and use IT has been a concern for many researchers. Prior studies have applied different theoretical foundations to study the relationship between IT use and productivity at individual level in post adoption scenarios and have provided mixed results.

  4. 4. Design Automation for Multidisciplinary Optimization : A High Level CAD Template Approach

    Author : Mehdi Tarkian; Johan Ölvander; Xiaolong Feng; Fredrik Elgh; Linköpings universitet; []
    Keywords : ;

    Abstract : In the design of complex engineering products it is essential to handle cross-couplings and synergies between subsystems. An emerging technique, which has the potential to considerably improve the design process, is multidisciplinary design optimization (MDO).MDO requires a concurrent and parametric design framework.
