  1. 1. Formal Approaches to Service-oriented Design : From Behavioral Modeling to Service Analysis

    Författare :Aida Čaušević; Paul Pettersson; Jonathan P. Bowen; Mälardalens högskola; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; service-oriented software engineering; formal modeling; service-oriented systems; resources; analysis; behavior; correctness check; Computer science; Datavetenskap; Computer Science; datavetenskap;

    Sammanfattning : Service-oriented systems (SOS) have recently emerged as context-independent component-based systems. In contrast to components, services can be created, invoked, composed and destroyed at run-time. Services are assumed to be platform independent and available for use within heterogeneous applications. LÄS MER

  3. 2. Type Ia Supernova Cosmology : Quantitative Spectral Analysis

    Författare :Gastón Folatelli; Ariel Goobar; Enrico Cappellaro; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Supernova; Cosmology; Spectroscopy; Physics; Fysik;

    Sammanfattning : Type Ia supernovae have been successfully used as standardized candles to study the expansion history of the Universe. In the past few years, these studies led to the exciting result of an accelerated expansion caused by the repelling action of some sort of dark energy. LÄS MER

  4. 3. Transient growth of disturbances in laminar pipe flow

    Författare :Lars Bergström; Luleå tekniska universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : Transient growth of disturbances is studied theoretically in pipe Poiseuille flow and experimentally both in pipe and plane Poiseuille flow. The theoretical results, based on the initial value problem, show that a large transient amplification occurs for small, angular dependent disturbances in pipe Poiseuille flow although all modes are damped.

  5. 4. A Formalized Approach to Multi-View Components for Embedded Systems : Applied to Tool Integration, Run-Time Adaptivity and Architecture Exploration

    Författare :Magnus Persson; Martin Törngren; De-Jiu Chen; Werner Damm; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; view; viewpoint; architecture; component; view integration; architecture exploration; component-based development; multi-view modeling; model-based design; CESAR; DySCAS; ESPRESSO;

    Sammanfattning : Development of embedded systems poses an increasing challenge fordevelopers largely due to increasing complexity. Several factors contribute tothe complexity challenge:• the number of extra-functional properties applying to embedded systems,such as resource usage, timing effects, safety. LÄS MER

  7. 5. Signal Processing Techniques in Mobile Communication Systems : Signal Separation, Channel Estimation and Equalization

    Författare :Ronnie Landqvist; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless mobile communications; signal processing; blind source separation; independent component analysis; beamforming; water filling; greedy algorithm; exact eigendecomposition; eigenvector algorithm; multiple-input multiple-output systems; the projection approximation subspace tracking algorithm with and without deflation; linear and non-linear principal component analysis; whitening; decorrelation; equalization; antenna arrays;

    Sammanfattning : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. LÄS MER
