  1. 1. Capacity allocation mechanisms for grid environments

    Författare :Peter Gardfjäll; Erik Elmroth; Bo Kågström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grid computing; capacity allocation; allocation enforcement; accounting; Grid-wide fairshare scheduling; Web services; Computer science; Datavetenskap;

    Sammanfattning : During the past decade, Grid computing has gained popularity as a means to build powerful computing infrastructures by aggregating distributed computing capacity. Grid technology allows computing resources that belong to different organizations to be integrated into a single unified system image – a Grid. LÄS MER

  3. 2. Methods for Capacity Allocation in Deregulated Railway Markets

    Författare :Abderrahman Ait Ali; Jonas Eliasson; Anders Peterson; Maria Börjesson; Yves Crozet; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway capacity; capacity allocation; train timetable; cost benefit analysis; deregulated market; spårkapacitet; kapacitetstilldelning; tågtidtabell; samhällsekonomisk analys; avreglerad marknad;

    Sammanfattning : Faced with increasing challenges, railways around Europe have recently undergone major reforms aiming to improve the efficiency and competitiveness of the railway sector. New market structures such as vertical separation, deregulation and open access can allow for reduced public expenditures, increased market competition, and more efficient railway systems. LÄS MER

  4. 3. Capacity development in international aid : A contribution to theory and practice

    Författare :Magnus Hagelsteen; Avdelningen för Riskhantering och Samhällssäkerhet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Capacity development; Capacity building; Partnership; Ownership; Power; Risk; Disaster;

    Sammanfattning : Although capacity development has been a key aspect of global aid policy for decades, success is limited. Capacity development is defined as a process, based on a partnership, to develop capacity to achieve a goal. LÄS MER

  5. 4. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

    Författare :Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

    Sammanfattning : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.

  7. 5. Multiantenna Cellular Communications : Channel Estimation, Feedback, and Resource Allocation

    Författare :Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; channel estimation; limited feedback; multicell communications; resource allocation;

    Sammanfattning : The use of multiple antennas at base stations and user devices is a key component in the design of cellular communication systems that can meet the capacity demands of tomorrow. The downlink transmission from base stations to users is particularly limiting, both from a theoretical and a practical perspective, since user devices should be simple and power-efficient, and because many applications primarily create downlink traffic (e.
