The purpose of this paper is to extract features from vibration signals measured from induction motors subjected to accelerated aging of bearings by fluting tests.

Aging tests were performed according to IEEE test procedures. The data acquisition involved the measurement of vibration signals using accelerometers that were installed on the bearings and on the motor casing. In this application, only two accelerometers, which were placed near the process end of the motor bearing, are used for data analysis and feature extraction studies. After the data collection, information from the two sensors was combined using simple sensor fusion method under the linearity conditions, and then spectral analysis and time‐scale analysis were performed. The fused vibration signal is decomposed into several scales using continuous wavelet transform (CWT) and its first scale is used to indicate the bearing degradation.

Bearing damage characterization was determined between 2‐4 kHz and some specific frequencies were calculated as harmonics of the bearing characteristic frequencies.

The bearing damage characteristics used in this study is occurred by the experimental study. In terms of the methodology, the use of the CWT shows the fault characteristics from the initial case.

The experimental study and data acquisition are based on the accelerated aging of the motor bearings. Hence, the real aging is represented by the accelerated one. But, this situation reflects same properties of the aging occurred in industrial environments. The methodology is also applicable to the hardware application.

There are two important aspects of this research: the experimental study and the application of CWT to get the potential defects, which will appear as a failure in future, from the healthy case of the motor bearings.

The chapter tries to understand how nuclear tests and the radiation fallouts in their aftermath can lead to cancer. It seeks to explore how our diseased ecological systems have resulted in silencing the birdsong and the spreading of cancer in the Anthropocene with reference to Terry Tempest Williams' (An environmentalist and Utah naturalist) two memoirs – “‘Refuge: An Unnatural History of Family and Place” and “When Women Were Birds: Fifty-Four Variations on Voice.” It would also try to factor in connections between climate change, pandemics like the COVID-19, and the onslaught of other terminal illnesses like cancer, all a result of mankind's anthropocentric hubris and domination of nature.

Mine would be a qualitative approach wherein I will refer to the original two texts mentioned for primary material and other sources for secondary references and analyze them from an ecofeminist perspective.

We need to establish the health of the Environment through reduced usage of nuclear weapons and by developing a language and an environmental praxis that doesn't separate the subject and the object and only then we can usher in biological egalitarianism, and restore the song of the whistling thrush again. We also need to revere our Mother Earth and see to it that she maintains her ecological balance through homeostasis.
