1. 6. Power Consumption and Joint Signal Processing in Fiber-Optical Communication

   Författare :Lars Lundberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent detection; erbium-doped fiber amplifier; phase-tracking; optical amplifier; optical frequency comb; digital signal processing; carrier-recovery; spatial division multiplexing; power consumption; Fiber-optical communication; multicore fiber; Raman amplification; energy-efficiency;

   Sammanfattning : The power consumption of coherent fiber-optical communication systems is becoming increasingly important, for both environmental and economic reasons. The data traffic on the Internet is increasing at a faster pace than that at which optical network equipment is becoming more energy efficient, which means that the overall power consumption of the Internet is increasing.

4. 8. Designing out waste - Exploring barriers for material recirculation

   Författare :Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

   Sammanfattning : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

5. 9. Inverse and Forward Approaches for Optimal Control and Estimation in Agent-Based Systems

   Författare :Yibei Li; Xiaoming Hu; Per Enqvist; Bijoy Ghosh; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomous systems; inverse optimal control; system identification; nonlinear systems; formation control; differential game; credit scoring.; Autonoma system; invers optimal styrning; system identifiering; olinjära system; formationsstyrning; differentialspel; kreditvärdering.; Optimeringslära och systemteori; Optimization and Systems Theory;

   Sammanfattning : This dissertation is concerned with three topics within the field of optimal control and estimation in dynamical agent-based systems, with potential applications that meet both engineering and societal needs. Firstly, the inverse optimal control problem is studied. LÄS MER

7. 10. Muscle injury and pain : effects of eccentric exercise, sprint running, forward lunge and sports massage

   Författare :Sven Jönhagen; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Muscle injury; muscle pain; DOMS; eccentric; massage; sprint runner; EMG;

   Sammanfattning : Muscle injuries are the most common injury in sports and both athletes and non-athletes are commonly seen in general practice and in the emergency department. Muscle pain is a common cause for absence from work and the cost to society is high. LÄS MER
