This document discusses modeling core losses for a doubly-fed wound rotor induction machine. It presents a core loss model that considers the core loss resistance to be variable and dependent on rotor and stator frequencies. The model is represented by a modified equivalent circuit for the machine. Results show that by properly selecting stator and rotor frequencies for different rotor speeds, the total core loss can be restricted to the rated value over a rotor speed range of 0 to 1 per unit.
The characteristics of a single phase induction motor are identical to three phase induction motor except that single phase induction motor has no inherent starting torque and some special arrangement have to be made for making itself starting.
Though single phase induction motor is not self-starting, we are using it because the three phase supply is not present at everywhere.
The voltage variation as well as power control of inductive load is essential in industrial sector.
The load may any motor or any inductive load.
We can use thyristor to this job but it is easier using TRIAC.
Speed Control of Induction Motor Drive Using Universal ControllerArif Shahriar
This is a presentation slide based on a paper from IEEE.
The paper describes how the speed of induction motor drive can be controlled using universal controller.
DOL Motor Starter is the least complex, least expensive and most basic Starting technique.Besides, it really gives the least temperature ascend inside the engine amid start-up of all the beginning techniques.
New Tools for Estimating Walking and Bicycling Demand
Track: Sustain
Format: 90 minute panel
Abstract: Walking and bicycling demand estimates can make a stronger case for investing in new facilities and are necessary inputs to important planning tasks. This session presents state-of-the-art tools to predict walking and bicycling demand at varying geographic scales. Tools include: 1) a framework to incorporate walking into regional travel demand models; 2) a method to estimate bicycle and pedestrian traffic based on count data; 3) new mode choice models; and 4) a web-based repository of non-motorized demand analysis tools.

Norman Garrick compares street network design from pre-1950 and post-1950, factors that help determine the overall safety of safe pedestrian travel, and explains why it is so obvious that the pandemic of sprawl development is to blame for unsafe, poorly designed, disconnected neighborhoods. Studies prove that Street Network Design has an integral role in providing safe, pedestrian friendly,and highly accessible communities. We must re-think the suburban model in order to reform emergency response.
In this thesis, I make as a first attempt a
mode choice model with smartphone data when data collection is passive. My research
consists in identifying and solving arising issues, due to the nature of the data, in order
to derive a dataset suitable for mode choice analysis. The key components of the
proposed methodology concern the detection of trips, activities and identi cation of the
trip purpose based on smarthphone data, and common issues to mode choice modeling,
such as the determination of the chosen mode and missing attributes of the unchosen
alternative, are addressed as well. The derived dataset is further enriched by complementary
datasets including socio-economic and meteorological information.

Here, I am uploading our b.tech final year project paper which is published in IRJET Journal.
We done a project on Vector speed control of induction motor.
This paper is completely written in simple words and this is the most easiest way of explaining.
And also ,here i am providing a youtube link how we done this project and its matlab simulation circuit and result analyzing...etc..,

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.
