A review of the employing of Wavelet transforms and Classifier Artificial intelligence (AI) methods for detecting power transmission difficulties
Abstract: Power systems use large interconnections to transmit and distribute electric power. For power transmission, the same voltage levels are used for minimum transmission losses. During power transmission faults may occur due to natural events such as lightning, strong wind, fire etc. Faults may occur between phase conductors to ground or between the phase conductors. Transmission line protection has been performed using the comparison of voltages and currents and activates the …

A Precise Clock Synchronization Algorithm in Network
Abstract: To execute a task in a synchronized manner in a distributed setting, we need the common idea of time. To accomplish this intention, clock synchronization is conceptualized. Clock drifting is an intrinsic property of a clock, which necessitates the synchronization. A network consists of nodes, which may execute appropriately or behave badly. The mischievous node may pose difficulty in clock synchronization. We require a method to ease the effect of …

Review of Vibration Monitoring Techniques Using Low Cost Sensors and Microcontrollers
Abstract: Healthy condition of machineries sustains and preserves the economy of the industry. Many of the products are manufactured by continual machining processes. Unforeseen failures are unbearable for industries which lead to costly repairs. Efficient supervision for condition monitoring and quick detection of the mechanical faults is a critical assignment in the current business era. Condition monitoring is the practice used to supervise the state of equipment/machineries, so, as to spot …

Power Quality Issues and Mitigation Strategies: A Review
Abstract: AbstractTo protect the power system recognition and arrangement of voltage (V) and current (I) issues are essential tasks. Most power quality (PQ) disturbances are unstable and ephemeral; the call for recognition and arrangement of voltages and current is proved. There are some intelligent system technologies which have dominance regarding fault analysis by using wavelet transform (WT), expert systems and artificial neural networks. As signals are classified in six classes: five …

IoT-Enabled Monitoring of AC Condensate Water for Quality Assessment and Early Detection of HVAC System Health
Abstract: The shortage of water and expensive reactive maintenance of HVAC are major problems in the modern building management. The paper introduces an Internet of Things (IoT)-enabled air conditioning (AC) condensate to water resource (predictive maintenance) and sustainable water reuse. The nature of our approach defines the quality of the condensate water at the baseline and indicates that it contains low levels of total dissolved solids (TDS) and has almost neutral …

Modeling of Overvoltage Protection by Lightning for a Grid-tied Solar Power System: A case of Vietnam
Abstract: AbstractThe solar power system has been widely developed due to its environmental friendliness and sustainability. Normally, PV panels would be preferable to set up on rooftop of building or free-standing in unsheltered areas. Therefore, the negative impacts on these systems from bad weather conditions, like storms and lightning, have been evident. Vietnam is located in the region of tropical monsoon weather, especially one of the three strongest thunderstorm areas in …

A STUDY OF INDIAN FEMALE SUBSTANCE ABUSERS IN TREATMENT DEMOGRAPHIC AND PSYCHOMETRIC VARIABLES
Abstract: THE ADDICTIVE PROCESSThe drug epidemic is several decades old in India. It has moved from culturally accepted recreational phenomena towards the newer drug use of Heroin, ocaine and other designer drugs. Routes of administration have shifted from oral intake and inhalation to chasing and injecting drug use. While this, in a way, represents man’s hedonistic nature, it is also a symptom of the inherent dysfunction in society and its social …
