    Sammanfattning : In this thesis we study algorithms and architectures that can provide a better Quality of Experience (QoE) for streaming video systems and services. With cases and examples taken from the application scenarios of football on mobile phones, we address the fundamental problems behind streaming video services. LÄS MER

  4. 3. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

    Författare :Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Sammanfattning : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. LÄS MER

  5. 4. Toward Dependable Multiple Path Planning for Autonomous Robots with Obstacle Avoidance and Congestion Control

    Författare :Lan Anh Trinh; Mikael Ekström; Baran Curuklu; Lucia Pallottino; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

    Sammanfattning : Over decades, automatic robots that are pre-programmed to perform repetitive tasks in industrial production has been reaching the cutting edge of technology. There is emerging the next development with autonomous control, where a robot is able to have some levels of its own decision, i.e. self-governing, without direct controls from humans. LÄS MER
