Abstract Background In ageing societies such as the United States, evaluating the incidence and survival rates of cancer in older adults is essential. This study aimed to analyse the incidence and survival rates of cancer in individuals aged 55 years

Instantaneous frequency (IF) of shaft rotation is pivotal for bearing fault diagnosis under variable speed operations. However, shaft IF cannot always be measured as tachometers are not allowed to be installed in every case due to design reasons and

Aplastic anemia (AA) is a bone marrow failure syndrome with high morbidity and mortality. Bone marrow (BM)‑mesenchymal stem cells (MSCs) are the main components of the BM microenvironment, and dysregulation of BM‑MSC adipogenic differentiation is

Short Time Fourier Transform (STFT) has been widely adopted for instantaneous frequency (IF) ridge extraction in bearing fault diagnosis under variable speeds. However, the readability of STFT-resulting time frequency representation (TFR) depends on

Instantaneous Frequency Estimation Via Multiple Ridge Integration Scheme for Bearing Fault Diagnosis
Publikováno v:
2018 Prognostics and System Health Management Conference (PHM-Chongqing).
One of the major obstacles of bearing fault diagnosis under variable shaft rotational speed is poor energy aggregation in time-frequency representation (TFR) for instantaneous frequency (IF) extraction. To address such a problem, a novel approach is
