Discounted cumulative gain. Discounted cumulative gain (DCG) is a measure of ranking quality. In information retrieval, it is often used to measure effectiveness of web search engine algorithms or related applications.
DC DG PMG. The permanent magnet alternator is the core of a successful, fuel efficient DC Diesel Generator. Our PMG is a brushless alternator that produces a high frequency AC output. There is an inbuilt magnetic field through permanent magnets. The efficiency of the unit is over 93%. We use a proprietary design built through our engineers that reduces electric ripple and maintains efficiency through a range of rpms. The unit is bearingless which reduces wear and tear and requires no maintenance.
