The early faulty gear diagnosis is most necessary in the industry. In the current decade, with the tremendous growth of ANN (Artificial Neural Network), the researcher planned to use DL (Deep Learning) methods to sketch out faults in gear in an early stage. Traditional gear fault diagnosis method mostly utilizes deep NN (Neural Network) related to tine sequence of gathered signals. In this instance, feature extraction in the direction of inverse time domain signal is commonly ignored. To overcome this issue, here in this paper, proposed Weighted Principal Component Analysis (WPCA) and BLSTM (Bi-Directional Long Short Term Memory) along with Swish Activation function for faulty gear diagnosis from the vibration signals. WPCA is utilized to extract multi-scale features related to faulty gear from the vibration signal. Likewise, BLSTM is used to classify the extracted features to diagnose the fault in an earlier stage. Several experiments were conducted to evaluate the proposed work of categorizing the defects in gear from the vibrating signal. Experiments were conducted on three kinds of the dataset to classify the type of faulty gear accurately. The proposed work proves its superiority in organizing the gear faults in a most efficient way than existing methods.
The current pandemic has pushed everyone to seek solutions for a reusable, stable and 100% effective face mask. This is due to common filter masks tend to gradually lose the ability to filter viruses and bacteria. All available masks for Covid-19 are mostly efficient 95%. These masks protect face from droplets released by another person in atmosphere which may contain Corona virus molecules. But these masks have efficiency of only up to 95% and these masks actively do nothing to stop Covid-19 from spreading. Thus, this type of masks is called Passive Masks On the contrary, Active Mask is absolutely stable because it does not only filter but inactivates the virus and/or bacteria, according to the systems used to tackle the viruses and bacteria. Active Masks are not only minimally 99.99% effective but also user has access to free airflow and thereby these types of masks are also comfortable for elderly or people with respiratory illness
