  1. 1. Towards Scalable Performance Analysis of MPI Parallel Applications

    Författare :Xavier Aguilar; Erwin Laure; David Black-Schaffer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel computing; performance monitoring; performance tools; event flow graphs; Computer Science; Datalogi;

    Sammanfattning :   A considerably fraction of science discovery is nowadays relying on computer simulations. High Performance Computing  (HPC) provides scientists with the means to simulate processes ranging from climate modeling to protein folding. LÄS MER

  3. 2. Collaboration and competition in firm-internal ideation management : Two alternatives – and a third way out

    Författare :Magnus Bergendahl; Mats Magnusson; Jennie Björk; Katharina Hölzle; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; innovation; ideation; collaboration; competition; ideas; idea generation; performance; firm-internal; ideation management; management; efficiency; employee.; Machine Design; Maskinkonstruktion;

    Sammanfattning : The passive reliance on ideas to spontaneously emerge within companies is today replaced with more active and continuous ideation management that embraces employees from different functions and knowledge-domains within the company to create and develop ideas. A frequently observed feature in the active management of ideation is the reliance on collaboration and competition mechanisms. LÄS MER

  4. 3. Secure and Trusted Mobile Commerce System based on Virtual Currencies

    Författare :Ioannis Kounelis; Sead Muftic; Fisseha Mekuria; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security; secure e-mail; mobile commerce; uicc; crypto currency; Computer Science; Datalogi;

    Sammanfattning : With the widespread usage of mobile devices and their applications, many areas of innovation have created a multitude of opportunities for mobile technologies to be deployed with very interesting effects. One such new area that emerged in the last few years is mobile commerce. LÄS MER

  5. 4. Turbulence modelling applied to the atmospheric boundary layer

    Författare :Werner Lazeroms; Arne Johansson; Geert Brethouwer; Evgeni Fedorovich; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulence; RANS models; explicit algebraic Reynolds-stress models; buoyancy; stable stratification; thermal convection; atmospheric boundary layer;

    Sammanfattning : Turbulent flows affected by buoyancy lie at the basis of many applications, both within engineering and the atmospheric sciences. A prominent example of such an application is the atmospheric boundary layer, the lowest layer of the atmosphere, in which many physical processes are heavily influenced by both stably stratified and convective turbulent transport.

  7. 5. Global Supply Chain Design : Exploring configurational and coordination factors

    Författare :Muhammad Abid; Lars Bengtsson; Mandar Dabhilkar; Magnus Wiktorsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Sammanfattning : This thesis addresses the topic of global supply chain design. One major challenge concerns how to manage the tension between separation and integration pertaining to the localization of business activities. In this regard Ferdows (2008) worked to create two new production network models (rooted production network and footloose production network). LÄS MER
