  1. 1. On performance limitations of large-scale networks with distributed feedback control

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Emma Tegling; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; microgrids; platooning; vehicular formation; multi-agent systems; H2 norms; fundamental limitations; consensus; Distributed control; large-scale networks; oscillator networks; power networks; power system dynamics; system performance; spatially invariant systems; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : We address the question of performance of large-scale networks with distributed feedback control. We consider networked dynamical systems with single and double integrator dynamics, subject to distributed disturbances. We focus on two types of problems. First, we consider problems modeled over regular lattice structures. LÄS MER

  2. 2. Reactive Concurrent Data Structures and Algorithms for Synchronization

    Detta är en avhandling från Stockholm, Sweden : KTH Royal Institute of Technology

    Författare :Phuong Ha; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-blocking; reactive; multi-word atomic primitives; online algorithms; shared memory; concurrent data structures; distributed data structures; randomization; online financial problems; synchronization; spin-locks;

    Sammanfattning : Parallelism plays a significant role in high-performance computing systems, from large clusters of computers to chip-multithreading (CMT) processors. Performance of the parallel systems comes not only from concurrently runningmore processing hardware but also from utilizing the hardware efficiently. LÄS MER

  3. 3. Mechanical properties of stabilized dredged sediments for sustainable geotechnical structures

    Sammanfattning : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. LÄS MER

  4. 4. The role of tectonics, structures and etch processes for the present relief in glaciated Precambrian besement rocks of SW Sweden

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Magnus Johansson; Karlstads universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landforms; morphotectonics; palaeosurfaces; GIS; digital elevation data; granite; deep weathering; saprolites; etchsurface; basins; structures; glacial reshaping; roche moutonnée; Naturgeografi; Physical Geography;

    Sammanfattning : In high latitudes, landscapes of low relief are known to contain residues of pre-glacial deep weathering, or etching, which testify to limited modification of the pre-glacial relief by the Pleistocene ice sheets. In this thesis landforms in all scales are classified according to their process of formation. LÄS MER

  5. 5. Micro-scale Platforms for Investigations of Biological Structures

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Anna Kim; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microfabrication; non-ionic surfactants; single-cell viability; hydrodynamic flow confinement; cell-to-cell connections; SU-8; Teflon AF; cell protrusions; free-standing probes; millimeter-waves;

    Sammanfattning : This thesis describes the development of innovative micro-scale platforms as a means to address the current challenges within the field of cell biology, and to provide an interface between miniaturized analytical technology and experimental systems for the life sciences. The work includes an analytical platform for rapid assessment of the viability of adherent single cells; a surface patterning strategy for investigations of cell-to-cell communication via protrusions; a versatile microfluidic probe in SU-8 hard-polymer, and a microfabricated millimeter-wave measurement system for the identification and characterization of niosome (non-ionic surfactant vesicle) constituents, which is operated in a label-free, non-invasive manner.
