    Sammanfattning : Heart disease is the leading cause of death in the world. Therefore, numerous studies are undertaken to identify indicators which can be applied to discover cardiac dysfunctions at an early age. LÄS MER

  4. 13. Synchronization Techniques in Parallel Discrete Event Simulation

    Författare :Jonatan Lindén; Bengt Jonsson; Christopher D. Carothers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parallel discrete event simulation; Discrete event simulation; PDES; Optimism control; Computer Science; Datavetenskap;

    Sammanfattning : Discrete event simulation is an important tool for evaluating system models in many fields of science and engineering. To improve the performance of large-scale discrete event simulations, several techniques to parallelize discrete event simulation have been developed. LÄS MER

  5. 14. Improving Performance and Quality-of-Service through the Task-Parallel Model​ : Optimizations and Future Directions for OpenMP

    Författare :Artur Podobas; Mats Brorsson; Georgi Gaydadjiev; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Task Parallel; OpenMP; Scheduling; OmpSs; multicore; manycore; Datalogi; Computer Science;

    Sammanfattning : With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them.

  7. 15. Parallel Stochastic Estimation on Multicore Platforms

    Författare :Olov Rosén; Alexander Medvedev; Petar Djuric; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive estimation; Parallelization; Bayesian estimation; Anomaly detection; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : The main part of this thesis concerns parallelization of recursive Bayesian estimation methods, both linear and nonlinear such. Recursive estimation deals with the problem of extracting information about parameters or states of a dynamical system, given noisy measurements of the system output and plays a central role in signal processing, system identification, and automatic control.
