    Sammanfattning : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. LÄS MER

  5. 4. Underwater radiated noise from Point Absorbing Wave Energy Converters : Noise Characteristics and Possible Environmental Effects

    Författare :Kalle Haikonen; Jan Sundberg; Sigray Peter; Uppsala universitet; []
    Nyckelord :Wave energy conversion; renewable energy; environmental impact; marine ecology; underwater noise;

    Sammanfattning : The conversion of wave energy into electrical energy has the potential to become a clean and sustainable form of renewable energy conversion. However, like all forms of energy conversion it will inevitably have an impact on the marine environment, although not in the form of emissions of hazardous substances (gases, oils or chemicals associated with anticorrosion).
