  2. 1. Low-density parity-check codes : unequal error protection and reduction of clipping effects

    Author : Sara Sandberg; David Declercq; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The invention of low-density parity-check (LDPC) codes made reliable communication possible at transmission rates very close to the theoretical limit predicted by Shannon. However, communication close to the Shannon limit requires very long codes and results in long delay and high encoder and decoder complexity. READ MORE

  4. 2. Evaluation of Family Check-Up and iComet : Effectiveness as well as Psychometrics and Norms for Parent Rating Scales

    Author : Annika Björnsdotter; Ata Ghaderi; Pia Enebrink; Malin Broberg; Uppsala universitet; []
    Keywords : Norms; rating scales; conduct problems; parent management training; intervention; SDQ; ERQ; parental knowledge and monitoring; Psychology; Psykologi;

    Abstract : This thesis compromise four studies, three regarding psychometrics and norms of parent rating scales, and one study regarding effectiveness of two different interventions. A normative sample consisting of 1443 parents with children aged 10 to 13 years old, was used in the Study I, II and III. READ MORE

  5. 3. Ontology Integration with Non-Violation Check and Context Extraction

    Author : Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Paul Johannesson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ontology matching and integration; semantic and pragmatic matching; semantic techniques; context; ontology and rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Matching and integrating ontologies has been a desirable technique in areas such as data fusion, knowledge integration, the Semantic Web and the development of advanced services in distributed system. Unfortunately, the heterogeneities of ontologies cause big obstacles in the development of this technique. READ MORE

  6. 4. Parity check systems, perfect codes and codes over Frobenius rings

    Author : Thomas Westerbäck; Olof Heden; Patric Östergård; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of five papers related to coding theory. The first four papers are mainly devoted to perfect 1-error correcting binary codes. The fifth paper concerns codes over finite Abelian groups and finite commutative Frobenius rings. In Paper A we construct a new class of perfect binary codes of length 15. READ MORE

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

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

    Abstract : 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. READ MORE
