  3. 3. Modelling and Analysis of Interconnects for Deep Submicron Systems-on-Chip

    Detta är en avhandling från Kista : Mikroelektronik och informationsteknik

    Författare :Dinesh Pamunuwa; [2003]
    Nyckelord :delay and noise modelling in VLSI circuits; cross-talk; interconnect modelling; timing analysis; transfer function; on-chip bus; bandwidth maximization; throughput maximization; repeater insertion; wire optimization;

    Sammanfattning : The last few decades have been a very exciting period in thedevelopment of micro-electronics and brought us to the brink ofimplementing entire systems on a single chip, on a hithertounimagined scale. However an unforeseen challenge has croppedup in the form of managing wires, which have become the mainbottleneck in performance, masking the blinding speed of activedevices. LÄS MER

  4. 4. Planning Models for Single Wire Earth Return Power Distribution Networks

    Detta är en avhandling från Kista : Mikroelektronik och informationsteknik

    Författare :Geofrey Bakkabulindi; Lennart Söder; Mikael Amelin; Peiyuan Chen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; power distribution planning; Single Wire Earth Return; distribution power flow; power system modeling; SRA - Energy; SRA - Energi;

    Sammanfattning : The high cost of grid extension to rural areas, often characterized by scattered communities with low load densities, requires the use of low cost electrification technologies to ensure economic viability. In Single Wire Earth Return (SWER) power distribution networks, the earth itself forms the current return path of the single phase system leading to significant cost savings on conductors, poles and poletop hardware compared to conventional systems.

  5. 5. Model Reduction Using Semidefinite Programming

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Aivar Sootla; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; semidefinite programming; model reduction; convex optimization;

    Sammanfattning : In this thesis model reduction methods for linear time invariant systems are investigated. The reduced models are computed using semidefinite programming. Two ways of imposing the stability constraint are considered. However, both approaches add a positivity constraint to the program. LÄS MER
