Recently, Asynchronous Motors are extensively used as workhorse in a multitude of industrial and high performance applications. Induction Motors (IM) have wide applications in today’s industry because of their robustness and low maintenance. A smart and fast speed control system, however, is in most cases a prerequisite for most applications. This work presents a smart control system for IM using an Adaptive Fuzzy Logic Controller (AFLC) based on the Levenberg–Marquardt algorithm. A synchronously rotating reference frame is used to model IM. To achieve maximum efficiency and torque of the IM, speed control was found to be one of the most challenging issues. Indirect Field-Oriented Control (IFOC) or Indirect Vector Control techniques with robust AFLC offer remarkable speed control with high dynamic response. Computer simulation results using MATLAB/Simulink® Toolbox are described and examined in this study for conventional PI and AFLC. AFLC presents robustness as regards overshoot, undershoot, rise time, fall time, and transient oscillation for speed variation of IFOC IM drive in comparison with classical PI. Moreover, load disturbance rejection capability for the designed control scheme is also verified with the AFL controller.

This paper presents the systematic procedure of the modeling and simulation of a Distribution STATCOM (DSTATCOM) for power quality problems, voltage sag and swell based on Sinusoidal Pulse Width Modulation (SPWM) technique. Power quality is an occurrence manifested as a nonstandard voltage, current or frequency that results in a failure of end use equipments. The major problems dealt here is the voltage sag and swell. To solve this problem, custom power devices are used. One of those devices is the Distribution STATCOM (D-STATCOM), which is the most efficient and effective modern custom power device used in power distribution networks. D-STATCOM injects a current in to the system to correct the voltage sag and swell.The control of the Voltage Source Converter (VSC) is done with the help of SPWM. The proposed D-STATCOM is modeled and simulated using MATLAB/SIMULINK software.

ECMFA 2015 - Energy Consumption Analysis and Design with Foundational UMLLuca Berardinelli
Wireless Sensor Networks (WSN) are nowadays applied to a
wide set of domains (e.g., security, health). WSN are networks of spatially distributed, radio-communicating, battery-powered, autonomous sensor nodes. WSN are characterized by scarcity of resources, hence an application running on them should carefully manage its resources. The most critical resource in WSN is the nodes’ battery.
In this paper, we propose model-based engineering facilities to analyze the energy consumption and to develop energy-aware applications for WSN that are based on Agilla Middleware. For this aim i) we extend the Agilla Instruction Set with the new battery instruction able to retrieve the battery Voltage of a WSN node at run-time; ii) we measure the energy that the execution of each Agilla instruction consumes on a target platform; and iii) we extend the Agilla Modeling Framework with a new analysis that, leveraging the conducted energy consumption measurements, predicts the energy required by the Agilla agents running on the WSN. Such analysis, implemented in fUML, is based on simulation and it guides the design of WSN applications that guarantee low energy consumption. The approach is showed on the Reader agent used in the Wild Fire Tracker Application.

Ekeeda - Mechatronics Engineering - Introduction to MechatronicsEkeedaPvtLtd
Mechatronics Engineering is a program in engineering which combines the fundamentals of mechanical engineering, electrical engineering, and computer engineering. It concentrates mainly on modeling, sensors, controllers, and real-time computer interfacing.
This program is developed due to demand from industries for an engineer with multi-disciplinary skills. Mechatronics engineers have to design, construct, and run production lines and automated processes with their skills, much like a production engineer but in a different field. This a field for students who have an interest in using computers and designing things. They should also be curious about how things work and what can be done to enhance them. They should be satisfactory in observing design and doing something with it. Ekeeda offers Online Mechatronics Engineering Courses for all the Subjects as per the Syllabus.
It‘s Math That Drives Things – Simulink as Simulation and Modeling EnvironmentJoachim Schlosser
You can benefit from Simulink, the software that Engineers love for doing their work
Engineers in industries like Aerospace, Automotive, Energy production, Industrial Machinery, Automation, Railway and many others use Model-Based Design with Simulink for an increasing amount of their applications. Simulink allows you to…
gain knowledge about the dynamics of your system and have a direct path to implementation
use the modeling language that most engineers speak.
Math underpins all Systems. Simulink is Math made real.
Whatever domain your system incorporates: It is likely that mathematics plays a part of it. For example, Simulink covers domains like:
Continuous time, Discrete time, Discrete event
State machine, Physical models, Text based algorithms
System environment, Digital hardware, Analog/RF hardware
Embedded software, Mechanical systems
MATLAB & Simulink provide a unified environment for all.
Functional testing those systems uses simulation and formal methods.
Begin to use Simulink for engineering mechatronic systems now.
Find ways to look at the system you could not do before, and save time in your development
Simulink is industry standard for engineering controls, signal processing.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
