  1. 11. Modeling prediction and pattern recognition in the early visual and olfactory systems

    Författare :Bernhard Kaplan; Lansner Anders; Fred Hamker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spiking neural networks; pattern recognition; self-organization; prediction; anticipation; visual system; olfactory system; modeling; Computer Science; Datalogi;

    Sammanfattning : Our senses are our mind's window to the outside world and determine how we perceive our environment.Sensory systems are complex multi-level systems that have to solve a multitude of tasks that allow us to understand our surroundings. LÄS MER

  3. 12. A Middleware for Self-Managing Large-Scale Systems

    Författare :Constantin Adam; Rolf Stadler; Arun Iyengar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomic computing; self-organization; decentralized control; web services; quality of service; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis investigates designs that enable individual components of a distributed system to work together and coordinate their actions towards a common goal. While the basic motivation for our research is to develop engineering principles for large-scale autonomous systems, we address the problem in the context of resource management in server clusters that provide web services.

  4. 13. Scalable Self-Organizing Server Clusters with Quality of Service Objectives

    Författare :Constantin Adam; Rolf Stadler; Giovanni Pacifici; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Autonomic computing; self-organization; decentralized control; web services; quality of service; Telekommunikation; Telecommunication; Telekommunikation;

    Sammanfattning : Advanced architectures for cluster-based services that have been recently proposed allow for service differentiation, server overload control and high utilization of resources. These systems, however, rely on centralized functions, which limit their ability to scale and to tolerate faults. LÄS MER

  5. 14. Programming Model and Protocols for Reconfigurable Distributed Systems

    Författare :Cosmin Ionel Arad; Seif Haridi; Gregory Chockler; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; distributed systems; programming model; message-passing concurrency; nested hierarchical composition; reactive components; software architecture; dynamic reconfiguration; multi-core; discrete-event simulation; peer-to-peer; testing; debugging; distributed key-value stores; data replication; consistency; linearizability; network partition tolerance; consistent hashing; self-organization; scalability; elasticity; fault tolerance; consistent quorums;

    Sammanfattning : Distributed systems are everywhere. From large datacenters to mobile devices, an ever richer assortment of applications and services relies on distributed systems, infrastructure, and protocols. Despite their ubiquity, testing and debugging distributed systems remains notoriously hard. LÄS MER

  7. 15. Inference of Hierarchical Structure in Complex Systems

    Författare :Olof Görnerup; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein evolution; Substitution groups; Modularity; Hierarchical dynamics; RNA world; Genetic code; Aggregation; Primordial evolution; Molecular evolution; Model reduction; Self-organization; Lumping; Emergence; Coarse graining;

    Sammanfattning : Hierarchical organization is a central property of complex systems. It is even argued that a system is required to be hierarchical in order to evolve complexity within reasonable time. A hierarchy of a system is defined as the set of self-contained levels at which the system operates and can be described on. LÄS MER
