21. Cost-effective Communication and Control Architectures for Active Low Voltage Grids
Sammanfattning : The monitoring and control of low voltage distribution grids has historically been disregarded due to the unidirectional flow of power. However, nowadays the massive integration of distributed energy resources into distribution grids, such as solar photovoltaics, distributed storage, electric vehicles and demand response programs, presents some challenges.

22. Life at stake when playing hide and seek : Concealing effects of prey colouration and visual backgrounds
Sammanfattning : A prey animal can use different strategies to avoid becoming eaten by predators. One such widely recognised strategy is the use of body colouration to decrease the risk of becoming detected, i.e. cryptic colouration. LÄS MER
23. Increasing the hosting capacity of distributed energy resources using storage and communication
Sammanfattning : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. LÄS MER
24. Optimization-based robot grasp synthesis and motion control
Sammanfattning : This thesis investigates the questions of where to grasp and how to grasp a given object with an articulated robotic grasping device. To this end, aspects of grasp synthesis and hand motion planning and control are investigated. LÄS MER
