1. 11. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

   Författare :Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

3. 12. Towards active engine mounting systems for commercial vehicles: modeling and analysis

   Författare :Hoda Yarmohamadi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear dynamic stiffness and damping; Actuators; Computational model; Conventional engine mount; Vibration isolation; Adaptronic mounting system; Model errors tolerance; Commercial vehicles;

   Sammanfattning : The vehicle engine mounting system, which consists of several mounts connecting the engine to the vehicle structure, not only supports the weight of the engine but also isolates the noise, vibration and the transmitted forces to the vehicle structure. At present conventional elastomeric mounts are widely used in engine mounting systems for commercial vehicles. LÄS MER

4. 13. High Frequency Model of Electrified Railway Propulsion System for EMC Analysis

   Författare :Kelin Jia; Rajeev Thottappillil; Hans Bängtsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic compatibility; railway; propulsion system; multitransmission line; ac motor modeling; vector fitting; fast transient;

   Sammanfattning : A model of the electrified railway propulsion system working in a wide frequency range is studied in this thesis. The high frequency modeling is the first stage to study and predict the Electromagnetic compatibility (EMC) problems in the electrified railway propulsion system, which are safety and reliability issues of high concern.

5. 14. A model-based design approach for heterogeneous NoC-based MPSoCs on FPGA

   Författare :Francesco Robino; Johnny Öberg; Shashi Kumar; KTH; []
   Nyckelord :System-level design; platform-based designembedded systems; field programmable gate arrays; integrated circuit design; integrated circuit modelling; network-on-chip; FPGA; NoC-based MPSoC; Simulink; common semantics domain; dataflow applications; design flow; embedded system; multiprocessor systems; network-on-chip; Computational modeling; Field programmable gate arrays; Mathematical model; Program processors; Prototypes; Semantics; ;

   Sammanfattning : Network-on-chip (NoC) based multi-processor systems-on-chip (MPSoCs) are promising candidates for future multi-processor embedded platforms, which are expected to be composed of hundreds of heterogeneous processing elements (PEs) to potentially provide high performances. However, together with the performances, the systems complexity will increase, and new high level design techniques will be needed to efficiently model, simulate, debug and synthesize them. LÄS MER

7. 15. Towards a Holistic Development Approach for Adaptable Manufacturing Paradigms : A Case Study of Evolvable Production Systems

   Författare :Afifa Rahatulain; Mauro Onori; DeJiu Chen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolvable Production Systems; Model-based Development; System Thinking; Viewpoints; Industriell ekonomi och organisation; Industrial Engineering and Management;

   Sammanfattning : Increasing global competition, market uncertainties and high product variance are a few of the factors posing challenges to the existing manufacturing industry. Having a quick response to market fluctuations and adapting to changing customer demands while maintaining shorter lead times and low costs are a few of the major challenges. LÄS MER
