  2. 1. Quantum Coherence for Light Harvesting

    Author : David Palecek; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Abstract : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. READ MORE

  4. 2. Efficient Energy Harvesting Interface for Implantable Biosensors

    Author : Janko Katic; Ana Rusu; Saul Rodriguez; Jonny Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Implantable biosensors; thermoelectric energy harvesting; energy harvesting interface; power management; DC-DC converters; dead time losses; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Energy harvesting is identified as a promising alternative solution for powering implantable biosensors. It can completely replace the batteries, which are introducing many limitations, and it enables the development of self-powered implantable biosensors. READ MORE

  5. 3. Hydrological effects of water harvesting techniques

    Author : Slah Nasri; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil mechanics; Väg- och vattenbyggnadsteknik; offshore technology; hydraulic engineering; hydrological effects; Civil engineering; rainwater harvesting; erosion;

    Abstract : The thesis investigates hydrological effects of large-scale water harvesting techniques on local water balances as well as sediment erosion. The techniques of tabias, soil contour ridges and small hill reservoirs are investigated. Pertinent processes are observed and simulated using various hydrological models.. READ MORE

  6. 4. Harvesting Based Communications for Wireless Control Systems : Event-Trigger and Reinforcement Learning Based Transmission Policies

    Author : Ruslan Seifullaev; Steffi Knorn; Anders Ahlén; Fredrik Gustafsson; Uppsala universitet; []
