  1. 1. Distributed resource allocation in networked systems using decomposition techniques

    Författare :Björn Johansson; Mikael Johansson; Daniel Palomar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : The Internet and power distribution grids are examples of ubiquitous systems that are composed of subsystems that cooperate using a communication network. We loosely define such systems as networked systems. These systems are usually designed by using trial and error. LÄS MER

  3. 2. On Distributed Optimization in Networked Systems

    Författare :Björn Johansson; Mikael Johansson; Asuman Ozdaglar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; resource allocation; networked systems; peer-to-peer; distributed optimization; Telecommunication; Telekommunikation; Automatic control; Reglerteknik;

    Sammanfattning : Numerous control and decision problems in networked systems can be posed as optimization problems. Examples include the framework of network utility maximization for resource allocation in communication networks, multi-agent coordination in robotics, and collaborative estimation in wireless sensor networks (WSNs).

  4. 3. Oral health-related quality of life and young adults

    Författare :Gunvi Johansson; Björn Söderfeldt; Björn Axtelius; Anna-Lena Östberg; Margareta Strandmark; Högskolan i Halmstad; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ODONTOLOGY; ODONTOLOGI;

    Sammanfattning : The aims were to describe and analyse measures for oral health-related quality of life (OHRQOL) from a Public Health perspective and to determine young adults' views on dental care. The methods used included one literature review (Paper I) and one empirical study with qualitative design (Paper II). LÄS MER

  5. 4. Mellan orten och kalifatet : En studie om utresandefenomenet

    Författare :Sara Johansson; Björn Johansson; Göran Larsson; Marcus Herz; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Islamic State; Radicalization; Foreign fighters; Especially vulnerable areas; Territorial stigmatization; Social representations; Moral disengagement; Social Work;

    Sammanfattning : Starting 2011, many travelled from other countries to support different parties of the Syrian revolution. Many came from Sweden, and many joined the Islamic State. Swedish “Syria travellers” often came from areas labelled as [especially] vulnerable. LÄS MER

  7. 5. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Författare :Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Sammanfattning : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. LÄS MER
