    Sammanfattning : With increased weather-dependent electricity production and electrification at the heart of the ongoing transition away from fossil fuels, peaks in electricity demand are set to increase and become increasingly difficult to meet, which threatens the functioning of the electric power systems that our society depends on. Time-varying electricity rates, which aim to incentivize electricity users to shift their electricity use in time, have been proposed as a key instrument in alleviating grid imbalances and bottlenecks.

  2. 2. Dynamic Characteristics of Floating Breakwaters

    Författare :Aurora Xiaomeng Lei; Chalmers University of Technology; []
    Nyckelord :floating breakwaters; couplings joints ; dynamic cables; dynamic response; line tension; wave attenuation; wave reflection;

    Sammanfattning : The dynamic behaviour of interconnected floating breakwaters has been studied theoretically and experimentally. For this type of shore-protection system, problems that must be dealt with include wave loads on the breakwaters caused by the interaction between the bodies and the waves, motions of the moored breakwaters caused by the waves, changed wave fields in front of and behind the breakwaters, and forces on the mooring cables and in interconnections between breakwater units.

  3. 3. Transient Air to Fuel Ratio Response in a Fuel Injected S.I Engine

    Författare :Göran Almkvist; Chalmers University of Technology; []
    Nyckelord :dynamic; A F; model; transient; air to fuel; response; time constant; film; behavior; lambda; time-delay; fuel; mass; deposit factor;

    Sammanfattning : Future emission standards make it necessary to focus on the conditions under which engine emissions are produced, especially before the catalyst light off. During practical driving conditions, such as those represented by the FTP 75 test cycle, the engine is operated very much under transient conditions regarding load and speed. LÄS MER

  4. 4. Dynamic response reconstruction using passive components

    Författare :Anders Johansson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER

  5. 5. Initial Studies of Dynamic Responses of Female and Male Volunteers in Rear Impact Tests

    Författare :Anna K Carlsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; dynamic response; rear impact; response corridors; volunteers; crash test; neck injury; whiplash; females;

    Sammanfattning : Whiplash Associated Disorder (WAD) - commonly denoted whiplash injury - resulting from vehicle impacts, is a worldwide epidemic. These injuries occur at relatively low changes of velocity (typically between 10-25 km/h) and in impacts from all directions. Rear impacts are however the most common in the accident statistics.
