    This paper presents a study on grid-connected WECS with PMSG. The application of non-conventional energy resources develops much rapidly to improve low carbon energy resources in India. Nowadays, we are going to depend on solar, wind for the fulfillment of energy demand. Wind energy applications develop much more rapidly than other renewable resources such as solar, geothermal, and so on in the 21st century. It becomes the third core energy resource following non-conventional fuels as oil and chemical. The electrical energy generated by wind power plants is the best developing and most promising renewable energy source. The wind is a clean, free, and limitless energy source. Wind Energy Generation Systems (WECS) are confronted with increasing demands for power quality and harmonic distortion control. With the advance in power electronics technology, the fast growth of variable speed WECS is now witnessed

    This paper presents a method of speed control Brushless DC Motor (BLDC) using a microprocessor. Brushless DC motor plays a vital role in all applications such as ling fans, pumps, automotive drivers, and robotic Automations, and Many technologies are available in the motor from controlling the speed of the motor as per the designed applications. In this regard, for control of speed in a BLDC motor application, using Ardunio Board with PWM Technique be used Speed Control of BLDC motor with various Techniques such as using mobile applications,  100th based BMS from the mobile phone. Brushless DC motors (BLDC) find wide applications in industries due to their high power density and ease of control. These motors are generally controlled using a three-phase power semiconductor bridge. In order to start and provide a proper commutation sequence to turn on the power devices in the inverter bridge, the rotor position sensors are required. The power devices are commutated sequentially every 60 degrees based on the rotor position. The motor requires suitable speed controllers to achieve the desired level of performance. In the case of permanent magnet motors, speed control is usually achieved by using a proportional-integral (PI) controller. Although conventional PI controllers are widely used in the industry due to their simple control structure and ease of implementation, these controllers pose difficulties where there are some control complexities such as nonlinearity

    Guidelines for the use and interpretation of assays for monitoring autophagy (4th edition)

    In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on these processes. These guidelines are not meant to be a dogmatic set of rules, because the appropriateness of any assay largely depends on the question being asked and the system being used. Moreover, no individual assay is perfect for every situation, calling for the use of multiple techniques to properly monitor autophagy in each experimental setting. Finally, several core components of the autophagy machinery have been implicated in distinct autophagic processes (canonical and noncanonical autophagy), implying that genetic approaches to block autophagy should rely on targeting two or more autophagy-related genes that ideally participate in distinct steps of the pathway. Along similar lines, because multiple proteins involved in autophagy also regulate other cellular pathways including apoptosis, not all of them can be used as a specific marker for bona fide autophagic responses. Here, we critically discuss current methods of assessing autophagy and the information they can, or cannot, provide. Our ultimate goal is to encourage intellectual and technical innovation in the field
