2. 1. Spectrum Sensing Algorithms Based on Second-Order Statistics

   Author : Erik Axell; Erik G. Larsson; Jan-Åke Larsson; Danyo Danev; Visa Koivunen; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Cognitive radio is a new concept of reusing spectrum in an opportunistic manner. Cognitive radio is motivated by recent measurements of spectrum utilization, showing unused resources in frequency, time and space. Introducing cognitive radios in a primary network inevitably creates increased interference to the primary users. READ MORE

4. 2. Methods for run time analysis of data locality

   Author : Erik Berg; Erik Hagersten; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

   Abstract : The growing gap between processor clock speed and DRAM access time puts new demands on software and development tools. Deep memory hierarchies and high cache miss penalties in present and emerging computer systems make execution time sensitive to data locality. READ MORE

5. 3. Apostolic Succession in the Porvoo Common Statement : Unity through a deeper sense of apostolicity

   Author : Erik Eckerdal; Sven-Erik Brodd; Tiit Pädam; Susan K Wood; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Apostolicity; apostolic succession; episcopal succession; episcopate; Porvoo Common Statement; episcopacy; ecclesiology; ecumenism; substantive apostolicity; successio; traditio; communio; koinonia; ecumenical method; Kyrkovetenskap; Ecclesiology;

   Abstract : A number of ecumenical dialogues have identified apostolic succession as one of the most crucial issues on which the churches need to find a joint understanding in order to achieve the unity of the Church.When the Porvoo Common Statement (PCS) was published in 1993, it was regarded by some as an ecumenical breakthrough, because it claimed to have established visible and corporate unity between the Lutheran and Anglican churches of the Nordic-Baltic-British-Irish region through a joint understanding of ecclesiology and apostolic succession.

6. 4. Information Integration in Computer Aided Design

   Author : Erik Lejon; Lars-Erik Lindgren; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Abstract : Information management during product development and over the lifecycle of products has become central to enable competitiveness in the engineering industry. Reuse and integration of information is essential to avoid duplicating efforts. READ MORE

7. 5. Degrees in Random Graphs and Tournament Limits

   Author : Erik Thörnblad; Svante Janson; Erik Broman; Daniel Kráľ; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Random graphs; degree distributions; degree sequences; graph limits; tournaments; Mathematics; Matematik;

   Abstract : This thesis consists of an introduction and six papers on the topics of degree distributions in random graphs and tournaments and their limits.The first two papers deal with a dynamic random graph, evolving in time through duplication and deletion of vertices and edges. In Paper I we study the degree densities of this model. READ MORE
