Lecture 1a Selection of Motor Rating.pptxVarsha506533
The document discusses factors to consider when selecting an electric motor's power rating, including thermal modeling to ensure efficient heat dissipation, motor duty classes, and determining ratings based on operating conditions. Proper sizing is important for reliability and productivity, and ratings indicate permissible current and voltage to safely run the motor within insulation temperature limits.
An AC motor operates using the interaction between a rotating magnetic field in the stator created by AC current and a magnetic field in the rotor. The stator is the stationary part containing windings that generate the magnetic field, while the rotor is the rotating part. Induction motors are the most common type and have a wound stator and rotor. In an induction motor, currents induced in the rotor by the stator create rotation, while in a synchronous motor the rotor carries its own magnetic field from a separate DC source and locks to the rotating magnetic field frequency. Synchronous motors have constant synchronous speed regardless of load but require an external starting mechanism, while induction motors have self-starting torque but a speed that decreases slightly with increasing load

An Implementation on Effective Robot Mission under Critical Environemental Co...IJERA Editor
Software engineering is a field of engineering, for designing and writing programs for computers or other electronic devices. A software engineer, or programmer, writes software (or changes existing software) and compiles software using methods that make it better quality. Is the application of engineering to the design, development, implementation, testingand main tenance of software in a systematic method. Now a days the robotics are also plays an important role in present automation concepts. But we have several challenges in that robots when they are operated in some critical environments. Motion planning and task planning are two fundamental problems in robotics that have been addressed from different perspectives. For resolve this there are Temporal logic based approaches that automatically generate controllers have been shown to be useful for mission level planning of motion, surveillance and navigation, among others. These approaches critically rely on the validity of the environment models used for synthesis. Yet simplifying assumptions are inevitable to reduce complexity and provide mission-level guarantees; no plan can guarantee results in a model of a world in which everything can go wrong. In this paper, we show how our approach, which reduces reliance on a single model by introducing a stack of models, can endow systems with incremental guarantees based on increasingly strengthened assumptions, supporting graceful degradation when the environment does not behave as expected, and progressive enhancement when it does.

INDUCTION MACHINES ANALYSIS USING LABVIEW SOFTWARE PACKAGE _Ijmet 10 04_085Isaac Samuel
Induction machines are widely used in many industries due to their robustness, ruggedness and easy maintenance feature. Due to the addition of power electronics devices and the complexity involved in the design of induction machines, their study and analysis can be very difficult. The use of software packages has been widely adopted to analyze and study the behaviours of induction machines. This work focused on the use
of an engineering software package known as Laboratory Virtual Instrument Engineering Workbench (LabVIEW). It is used in this work to study the behaviour and characteristics of induction machines. LabVIEW was utilized due to its cheap and userfriendly feature. This work shows that induction machines can be completely analyzed using related mathematical equations for performance analysis.

Multi criteria decision making (MCDM) techniques in today’s organizations, as a key
to performance measurement comes more to the foreground with the advancement in the high
technology. During recent years, many studies have been conducted to obtain a ranking
among many alternatives via measuring performance of each of them against many criteria.
Managerial decision making problems like supplier selection, weapon selection, project
selection, site selection etc are dealt with many multi criteria decision making methods like
TOPSIS, AHP-TOPSIS (Technique for Order Preference by Similarity to Ideal Solution),
PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation),
ELECTRE, VIKOR etc in crisp throughout the literature. In this work, we first compare
several MCDM methodologies to validate the consistency of them on a standard dataset of
plant layout problem. We proposed M-TOPSIS, A-TOPSIS procedure to select a suitable
layout for the comparative study. Results of M-TOPSIS and A-TOPSIS have been employed
to build an unsupervised artificial neural network (ANN) to obtain a new ranking of
alternatives. This study proposes an approach of deriving the rank value, in order to get
optimal configuration, from the average of more than one set of rank results obtained through
the deployment of MCDM methodologies

IRJET- An Over View of Qualitative Structural Analysis using Diagrammatic Rea...IRJET Journal
This document discusses diagrammatic reasoning in qualitative structural analysis. It describes how structural engineers use diagrammatic representations to intuitively determine the deflected shape of structures under loads. The researchers built a system called REDRAW that qualitatively solves structural analysis problems using diagrammatic reasoning similar to humans. REDRAW uses both a symbolic representation of engineering knowledge and a diagrammatic representation to manipulate and inspect diagrams, propagating constraints until reaching a stable deflected shape. The document argues that structural analysis provides a realistic domain for studying diagrammatic reasoning, as diagrams in this field represent real-world objects and their interpretation depends on domain knowledge.

IRJET- Development of a Neural Network based Model for Construction Proje...IRJET Journal
This document describes the development of a neural network model to predict construction project management effectiveness. 12 factors that influence effectiveness were identified, including factors related to the project manager, project team, and planning/control efforts. A questionnaire was used to collect historical project data on these factors. A neural network model was developed and trained using the data to establish relationships between the input factors and output of project cost variation, which measures management effectiveness. The model can be used as a decision support tool to evaluate management strategies and optimize resource allocation to improve effectiveness.

IRJET- Singular Identification of a Constrained Rigid RobotIRJET Journal
This document presents a singular identification procedure for identifying the parameters of a constrained rigid robot model. It begins with describing the constrained robot model and how it can be represented as a singular system. It then discusses singular equivalency, in particular strong equivalency, which transforms the original singular system into an equivalent regular state space model. This is important to reduce the number of initial conditions and improve identification. The document proposes using recursive least squares identification on the strongly equivalent model to identify the robot parameters. Simulation results on a robot arm model show that this approach provides significantly better parameter estimation convergence and output tracking compared to previous identification techniques for constrained robot models.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
