Internet of Things (IoT) is an integration the Sensor, Embedded, Computing, and Communication technologies. The purpose IoT to provide seamless services anything, anytime at any place. technologies play a crucial role everywhere, which brings fourth revolution disruptive after internet Information Technology (ICT). Research & Development community has predicted that impact will be more than ICT on society, improves well-being society industries. Addressing predominant system-level design...
Nowadays, the number of aging high-rise civil structures is growing throughout world, and most them use concrete as a building material. Concrete may lose its strength due to continuous loading environmental impacts. As result, damage (crack spall) occur on exterior surface structure. Whenever these deformities are left unexplored untreated, integrity structure be compromised. Therefore, regular maintenance needed. Some previous vision-based studies have used drone vehicle capture record...
This paper proposes a novel Variational mode decomposition (VMD) algorithm for bearing fault diagnosis. The Fast Fourier Transform fails to analyse the transient and non-stationary signals. Discrete transform Empirical do not have ability attain accurate Intrinsic functions under dynamic system conditions because characteristic of exponentially decaying dc offset is consistent. EMD fully data-driven, model-based, adaptive filtering procedure extracting signal components. technique has high...
Concrete is one of the primary and most commonly used materials for construction buildings, roads, bridges, dams. But it may lose its strength with age, moisture content, or due to other factors. As a result, little damage (crack spall) these structures lead sudden collapse breakage, which in turn can decimate many lives economic losses. Hence, ensure their proper load, accurate screening concrete surface necessary maintenance engineers understand evaluate severity damage. Few preceding...
Bearing health analysis plays a significant role in industry to improve reliability and performance of critical processes by alarming the faults at early stages. Conventional techniques do no guarantee detect stages because low energy bearing frequencies get suppressed stern noise higher vibrations. The Fast Fourier Transform fails analyse transient non-stationary signals directly. This paper performs signal on vibration data ball using Variational mode decomposition (VMD). Firstly,...

Stirred by this, we proposed a lightweight device...
The kinematics of the bearing is erratic and random in nature requires timely attention to avoid any catastrophic failure. In this study, authors have proposed analysed amplitude frequency modulated signals emanating from using four steps, i.e. standardisation, empirical mode decomposition, principal component analysis (PCA), envelope cepstral techniques. First, standardised are decomposed into stationary non‐linear modes called intrinsic functions (IMFs). approach, PCA applied on IMFs...
