  1. 1. Associations between physical activity and metabolic risk factors in children and adolescents : The European Youth Heart Study (EYHS)

    Författare :Nico Samuel Rizzo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Adolescents; Cardiorespiratory Fitness; Cardiovascular Disease; Children; Lifestyle; Metabolic Syndrome; Physical Activity; Public Health;

    Sammanfattning : Background: Sedentary lifestyles and concomitant behaviours such as smoking and poor dietary habits are increasingly implied in the rise of non communicable diseases which have become a major cause of morbidity and death not only in high income countries but also in lower income countries. This development makes it increasingly important to study aetiological factors that are linked to features of the metabolic syndrome in children and adolescents. LÄS MER

  3. 2. Modeling and control of actuators and co-surge in turbocharged engines

    Författare :Andreas Thomasson; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. LÄS MER

  4. 3. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER

  5. 4. Energy efficiency in heritage buildings : Conservation approaches and their impact on energy efficiency measures

    Författare :Tomas Örn; Agatino Rizzo; Sofia Lidelöw; Andrea Luciani; Elena Lucchi; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency heritage buildings; Arkitektur; Architecture;

    Sammanfattning : The impeding climate change challenge urges for a reduction of energy use in the built environment. Buildings account for nearly 40% of the total energy use and about 35% of the greenhouse gas emissions in Europe. LÄS MER

  7. 5. On the Relative Utility of 3D Interfaces

    Författare :Monica Tavanti; Mats Lind; Antonio Rizzo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Människa-dator-interaktion; human-computer interaction; information visualization; 2D and 3D interfaces; Människa-dator-interaktion; Information technology; Informationsteknologi; datavetenskap med inriktning människa-dator interaktion; Computer Science; human-computer interaction;

    Sammanfattning : Three-dimensional (3D) interfaces are made with the ambition to reinvent traditional two-dimensional (2D) displays into intuitive 3D environments that allow natural interactions and guarantee users’ satisfaction. However, reality is far from the expectations and 3D interfaces remain experimental. LÄS MER
