    Sammanfattning : Fans are often used in equipment such as home appliances andelectronic equipment where the margin of profit is small butcustomers demands on a low noise level are high. Therefore,methods for predicting the noise emitted by an applicationincluding one or several fans are desirable in order toimprove, accelerate and reduce the cost of low-noise design. LÄS MER

  2. 2. Aircraft Systems Modeling Model Based Systems Engineering in Avionics Design and Aircraft Simulation

    Detta är en avhandling från Linköping : Linköping University Electronic Press
