It is imperfect to evaluate a subsampling variable selection method using only its prediction performance. To further assess the reliability of subsampling variable selection methods, dummy noise variables of different amplitudes were augmented to the original spectral data, and the false variable selection number was recorded. The reliabilities of three subsampling variable selection methods including...
The moisture diffusion phenomenon and moisture stress in a specific LED module was studied in this paper. Firstly, the finite element model of the LED module was built. The moisture diffusion distribution at operation condition with 25 °C ∼ 85 °C, was analyzed. Secondly, the temperature distribution and moisture distribution of the LED module during reflow soldering process were simulated at the initial...
Based on intensive study of CAN & TCP/IP protocol, an active atmospheric boundary layer(ABL) simulator for wind tunnel test was developed, the multi-axes in-phase and multi-locomotion control was achieved. The experiment results show that the high controlling precision, fast responses, good performance and stability can be found in this system.
With the rapid expansion of network application, more and more customer reviews are available online. In this paper, A method for opinion analysis based on the fusion of multiple classifiers was presented, reliability function was introduced to select the text that is hard to determine by the main classifier, for these texts, multiple classifiers were used to determine which category the unlabeled...
According to the high-reliability requirement of emergency trip system (ETS) for steam turbine, a triple modular redundant ETS system is presented in detail in this paper. The system consists of groups of input modules gathering data from sensors, system bus, main controllers running the same application program, and groups of output modules, all of which are configured to triple hardware redundancy...
