2. 1. Technological Discontinuities and Industrial Dynamics

   Author : Ellinor Ehrnberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion; radical innovation; bibliometrics; technological forecasting; patents; technological system; machine tools; technological discontinuity;

   Abstract : A technological discontinuity is a substantial change in the set of technological competences required to design and produce a product, often resulting in a significant change in the price/performance ratio of a product. Established firms often face severe difficulties in adjusting to a discontinuity. READ MORE

4. 2. Design and Control of Products Including Parts with Impacts

   Author : Jenny Jerrelind; KTH; []
   Keywords : Nonlinear Dynamics; Impacts; Discontinuities; Subsystems; Chaos; Irregular Behaviour; Printer Dynamics; Suspensions; Coupled Systems; Control; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Today's product development process should be rapid andcost-efficient, and should result in innovative and reliableproducts. A crucial factor is the dynamic behaviour of theproduct. READ MORE

5. 3. Topics in Simulation and Stochastic Analysis

   Author : Mikael Signahl; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; stochastic heat equation; stochastic wave equation; error rates; truncated Levy process; discontinuities; optimal decay rate; digital communication system;

   Abstract : Paper A investigates how to simulate a differentiated mean in cases where interchanging differentiation and expectation is not allowed. Three approaches are available, finite differences (FD's), infinitesimal perturbation analysis (IPA) and the likelihood ratio score function (LRSF) method. READ MORE

6. 4. Techniques for Localization of Insulation Degradation along Medium-Voltage Power Cables

   Author : Ruslan Papazyan; Roland Eriksson; Fred Steennis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Attenuation measurement; cross-linked polyethylene insulation; discontinuities; localization; mass-impregnated insulation; numerical analysis; parameter estimation; power cable metallic screen; scattering parameters; time domain reflectometry; velocity measurements; water treeing; Elkraftteknik; Electric power engineering; Elkraftteknik;

   Abstract : Time Domain Reflectometry (TDR) has been used for localization of transmission line discontinuities in diverse applications. Various challenges have to be addressed when applying TDR for localization of insulation degradation in power cables. READ MORE

7. 5. Switched Bond Graphs : Simulation and Analysis

   Author : Krister Edström; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bond graphs; Hybrid systems; Modeling; Simulation; Causality; Discontinuities;

   Abstract : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.
