2. 21. Hybrid Solvers for the Maxwell Equations in Time-Domain

   Author : Fredrik Edelvik; Per Lötstedt; Jan Hesthaven; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maxwell s equations; time-domain; finite volume methods; finite element methods; hybrid solver; dispersive materials; thin wires; Beräkningsvetenskap; Scientific Computing;

   Abstract : The most commonly used method for the time-domain Maxwell equations is the Finite-Difference Time-Domain method (FDTD). This is an explicit, second-order accurate method, which is used on a staggered Cartesian grid. The main drawback with the FDTD method is its inability to accurately model curved objects and small geometrical features. READ MORE

4. 22. Hybrid and Dynamic Substructuring Methods for Energy Flow Analysis

   Author : Anders Wilson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fractional derivatives; structural modeling; mid-frequency; finite element method FEM; vibro-acoustics; statistical energy analysis SEA; dynamic substructuring; hybrid analysis; viscoelasticity;

   Abstract : Modeling techniques and solution tools to analyze the dynamic and vibro-acoustic behavior of complex built-up structures are matters of increasing interest, especially for thin walled structures as in transportation vehicles, such as automobiles, trucks, trains and aircraft. In structures like these, the reduction of cost, weight, sound and vibration levels are primary issues for research and development. READ MORE

5. 23. The role of the board chair : Changing expectations and hybrid organizations

   Author : Anup Banerjee; Mattias Nordqvist; Kajsa Haag; Martin Carlsson-Wall; Jarmo Vakkuri; Jönköping University; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : The purpose of this dissertation is to enhance our understanding of the changing role of the board chair and what this means for hybrid organizations and their board work. Historically, the role of the boards and their chairs evolved around safeguarding shareholders’ financial interests. READ MORE

6. 24. Supporting Data Interaction and Hybrid Asymmetric Collaboration Using Virtual Reality Within the Context of Immersive Analytics

   Author : Nico Reski; Aris Alissandrakis; Andreas Kerren; Petra Isenberg; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D gestural input; 3D radar charts; 3D user interfaces; empirical evaluation; head-mounted display; hybrid asymmetric collaboration; immersive analytics; spatio-temporal data interaction; user interface design; virtual reality; 3D-handinteraktion; 3D-radardiagram; 3D-användargränssnitt; design av användargränssnitt; empirisk utvärdering; huvudburen display; hybrid-asymmetrisk samarbete; immersiv analys; virtuell verklighet; Computer Science; Datavetenskap; Informations- och programvisualisering; Information and software visualization;

   Abstract : Immersive display and interaction technologies have rapidly evolved in recent years, offering advanced techniques compared to traditional Human-Computer Interaction. Computer-generated Virtual Environments viewed with stereoscopic depth perception and explored using 3D spatial interaction can represent more accurately how humans naturally interact in the real world.

7. 25. Hybrid cellular-broadcasting infrastructure systems : radio resource management issues

   Author : Aurelian Bria; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

   Abstract : This thesis addresses the problem of low-cost multicast delivery of multimedia content in future mobile networks. The trend towards reuse of existing infrastructure for cellular and broadcasting for building new systems is challenged, with respect to the opportunities for low cost service provision and scalable deployment of networks.
