  1. 1. Efficient Partitioning of Dynamic Structured Grid Hierarchies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Steensland; Uppsala universitet.; Uppsala universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scientific computing; partitioning; structured grids; adaptive mesh refinement; dynamic load balancing; Scientific Computing; Beräkningsvetenskap;

    Abstract : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.

  2. 2. Demand Response Polices for the Implementation of Smart Grids

    University dissertation from Delft, NL : Delft University of Technology

    Author : Elta Koliou; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; demand response; smart grids; dynamic pricing; balancing; policy; tariffs; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the grasp of a smart grid in sight, discussions have shifted the focus of system security measures away from generation capacity; apart from modifying the supply side, demand may also be exploited to keep the system in balance. Specifically, Demand Response (DR) is the concept of consumer load modification as a result of price signaling, generation adequacy, or state of grid reliability. READ MORE

  3. 3. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

    University dissertation from Stockholm : KTH

    Author : Tahir Naseer Qureshi; KTH.; [2009]
    Keywords : Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

    Abstract : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. READ MORE

  4. 4. Observing the dynamic behaviour of large distributed systems to improve development and testing : an empirical study in software engineering

    University dissertation from Linköping : Linköpings universitet

    Author : Johan Moe; Linköpings universitet.; Linköpings universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : Knowledge about software systems' dynamics is a prerequisite for the successful design, testing and maintenance of viable products. This work has evolved a number of tools based on observation of software system dynamics in a commercial environment, resulting in a method and a toolbox that can be used by testers and maintainers to improve both the system and its test environment.

  5. 5. Domain-based partitioning for parallel SAMR applications

    University dissertation from Uppsala universitet

    Author : Johan Steensland; Uppsala universitet.; Uppsala universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Abstract : This thesis presents a study of domain-based partitioning techniques for dynamic structured grid hierarchies, occuring in structured adaptive mesh refinement (SAMR) methods. Such methods for obtaining the numerical solution to partial differential equations yield highly advantageous ratios for cost/accuracy as compared to methods based upon static uniform approximations.
