Levels. converter in case of transformer flux walking. The PWM. outputs from the dsPIC DSC are firing
  • Comparison of Block and Random Ethylyene-Octene Copolymers Based on the Structure and Elastomeric Properties (.pdf)
    The structure and elastomeric properties of the novel olefinic block copolymers (OBCs) were studied by DSC, WAXS, AFM combined with stress-strain, and strain recovery measurement. Their structure and properties were compared with the conventional statistical ethylene-octene (EO) copolymers
  • Importance of an Optimised TA-MS Interface (.pdf)
    Evolved gas analysis techniques can be used to provide important information about decomposition or desorption processes when coupled to thermal analysis techniques such as DSC, TGA, and DTA. Mass spectrometry (MS) offers a number of advantages for evolved gas analysis from TGA instruments over
  • Field-oriented control for motors
    under FOC. The DMCI shows application feedback graphically for quick analysis and lets engineers dynamically change program variables for testing. A digital-signal controller (DSC) contains all logic and measurement functions on a single chip for field-oriented control of permanent-magnet synchronous
