1. 1. Capacity allocation mechanisms for grid environments

   Författare :Peter Gardfjäll; Erik Elmroth; Bo Kågström; Umeå universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

   Författare :Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; 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.

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

   Författare :Emil Björnson; Björn Ottersten; Mats Bengtsson; Marios Kountouris; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

7. 5. Location-aware resource allocation in mobile edge clouds

   Författare :Chanh Le Tan Nguyen; Erik Elmroth; Cristian Klein; Maarten Van Steen; Umeå universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mobile Edge Clouds; Resource Allocation; Quality of Service; Application Placement; Workload Prediction; Computer Systems; datorteknik; Computer Science; datalogi;

   Sammanfattning : Over the last decade, cloud computing has realized the long-held dream of computing as a utility, in which computational and storage services are made available via the Internet to anyone at any time and from anywhere. This has transformed Information Technology (IT) and given rise to new ways of designing and purchasing hardware and software. LÄS MER
