  • A New Paradigm Of Object Detection: Using Transformers

    To understand how Transformers make an end-to-end object detection simpler, the researchers pitted it against the state-of-the-art Faster R-CNN, a traditional two-stage detection system. In case of Faster R-CNN, as shown above, object bounding boxes are predicted by filtering over a large number of coarse candidate regions, which are generally

  • Transformer Health Condition Monitoring Through GSM Technology

    Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can pre-vent faults that are costly to repair and result in a loss of service. Current systems can provide information about the state of a transformer, but are either of-fline or very expensive to implement.

  • The Importance of CO2 in Fire Suppression Applications

    The main advantages of CO2 and Fire Suppression Systems is that since CO2 is an inert gas there is no clean-up beyond the actual fire. Unlike water or foaming agents, CO2 will not harm any of the components. Therefore, cleanup is limited to the fire damage only. In addition, CO2 is effective on a wide range of flammable and combustible materials.
