  2. 11. From LOTOS specifications to distributed implementations

    Author : Peter Sjödin; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This Thesis presents a technique for automatic generation of implementations from their formal LOTOS specifications. The technique focuses on implementations executing in distributed systems where processes communicate by asynchronous message passing. Implementations are specified in an executable subset of LOTOS.

  4. 12. Distributed Optimization for Control and Estimation

    Author : Shervin Parvini Ahmadi; Anders Hansson; Anders Helmersson; Daniel Axehill; Tamas Keviczky; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Adopting centralized optimization approaches in order to solve optimization problem arising from analyzing large-scale systems, requires a powerful computational unit. Such units, however, do not always exist. READ MORE

  5. 13. Simplified Graphical Approaches for CDMA Multi-User Detection, Decoding and Power Control

    Author : Peng Hui Tan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code-division multiple access; belief propagation; large system analysis; iterative decoding; multiuser detection; power control;

    Abstract : The individual optimal detector for code-division multiple-access (CDMA) systems is based on the marginal a posteriori distribution of the transmitted bits. The marginalization is in general hard since a summation is required, which grows exponentially in scope with the number of active users. READ MORE

  6. 14. Implementation of complex polarization propagator theory for linear response properties of large molecular systems

    Author : Manuel Brand; Patrick Norman; Berta Fernández Rodríguez; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

    Abstract : Since its beginning, the remarkable development from the first commercially available computers toward exascale supercomputers just within the span of a lifetime has been closely intertwined with the perpetual quest for the utilization of the arising computing power for the avail of theoretical chemistry. With the aim of further pushing the limits of computationally accessible molecular system sizes, this thesis includes the presentation of programming efforts, which brought forth two quantum chemical software codes, as well as a range of ab initio studies on carbon-based systems, enabled by the former.

  7. 15. High Performance Adaptive Finite Element Methods : With Applications in Aerodynamics

    Author : Niclas Jansson; Johan Hoffman; Johan Jansson; Vincent Heuveline; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The massive computational cost for resolving all scales in a turbulent flow makes a direct numerical simulation of the underlying Navier-Stokes equations impossible in most engineering applications. Recent advances in adaptive finite element methods offer a new powerful tool in Computational Fluid Dynamics (CFD). READ MORE
