  1. 16. Time and space efficient algorithms for packet classification and forwarding

    Författare :Mikael Sundström; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem;

    Sammanfattning : The Internet consists of a mesh of routers (nodes) connected by links (edges) and the traffic through the Internet is divided into flows where each flow is an ordered sequence of packets, or datagrams. Each packet consists of a header and a piece of data, also referred to as payload. LÄS MER

    Sammanfattning : This thesis is an investigation into how meta-heuristic multi-objective optimisation processes (genetic algorithms driven by evolutionary solvers) can bring about materials-related advantages in architectural performance. It redefines the architect’s and engineer’s role from being designers of a singular space or structure to being designers of entire species of spaces, and discusses a particular method – anticipatory adaptive assemblages (AAA) – that allows such processes to produce many generations of design iterations that eventually yield individuals optimised for a set of predefined objectives.

    Sammanfattning : Optimization techniques always play an important role in designing high-performance wireless systems. This presented thesis studies a selected set of optimization problems for different kinds of wireless networks, making use of mathematical programming techniques to find optimal solutions and of efficient heuristics to find near-optimal solutions.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Allocating resources, goods, agents (e.g., humans), expertise, production, and assets is one of the most influential and enduring cornerstone challenges at the intersection of artificial intelligence, operations research, politics, and economics. LÄS MER

  7. 20. Convex Optimal Power Flow Based on Second-Order Cone Programming: Models, Algorithms and Applications

    Författare :Zhao Yuan; Mohammad Reza Hesamzadeh; Mario Paolone; KTH; []
