In sensor networks, due to power outage at a sensor node, hardware dysfunction, or bad environmental conditions, not all sensor samples can be successfully gathered at the sink. Additionally, in the data stream scenario, some nodes may continually miss samples for a period of time. In this paper, a sparsity-based online data recovery approach is proposed. We construct an overcomplete dictionary composed...
In order to optimize the performance of the steam turbine unit performance monitoring system, improve the reliability, stability and accuracy of the system, a new idea to establish target value surface and coal consumption growth surface in different load is presented. Take an imported supercritical steam turbine unit, which capacity is 600 MW, as an example to expound the design idea, the mathematic...
