It then outlines goals of increasing customer satisfaction by allowing all operations to be done remotely via online and mobile banking. This would help the bank penetrate new international markets and rural areas in a faster, safer, and more cost-effective manner. A task plan is proposed to implement necessary changes to the system through tasks like requirement analysis, design, testing, and deployment.
DLD Intro
Digital logic design is the basis of electronic systems like computers and cell phones. It uses binary numbers (zeros and ones) to represent information and process input/output operations. Digital logic employs logic gates that perform functions like AND, OR, and NOT to translate binary input signals into specific outputs. Career opportunities include developing device infrastructures using components like information storage, signal transmission, and information processing. Engineers work to improve performance, decrease energy usage, and debug issues.

Presentation Fire Alarm_Project
This document describes the components and working of a simple fire alarm circuit project. The circuit uses a thermistor to detect changes in temperature, which then triggers a transistor and sounds a buzzer. Key components are a thermistor, transistor, diode, capacitor, resistors and a 6V buzzer. As temperature rises, the thermistor's resistance decreases, increasing the voltage across a resistor to turn on the transistor and activate the buzzer. The circuit aims to detect fires and prevent damage through a simple, low-cost design.
Inrush current
The document discusses inrush current in transformers. It defines inrush current as the maximum, instantaneous input current drawn by an electrical device when first turned on. When a transformer is energized, inrush current occurs as both a source-free response and a forced response to the applied AC voltage. The magnitude of inrush current depends on factors like the residual flux in the transformer core and the phase of the AC voltage wave when the switch is closed. Inrush current can be several times the normal full-load current and decays within 5-10 cycles but may exceed 25 times the full-load rating initially.

A temperature controller is a device that monitors the temperature of a system using a sensor and compares it to a set point. If the temperature deviates from the set point, the controller performs calculations to control a heater or other equipment to regulate the temperature. The document describes a temperature controller circuit that uses a thyristor, thermostat, diode bridge rectifier, and capacitor to allow current to flow through a heater when the temperature drops below the set point in order to heat the system back up. Temperature controllers are commonly used to control engine temperature, cooling systems, chemical processes, and more.

Intelligent Electric Power Management Using Zigbee with Advanced Metering Inf...
This project mainly focuses on reduction of power cut and power theft. The main reason for the power cut is shortage of power in the generation unit. We can rectify this problem through our project.
Whenever the generation falls behind a particular limit (it is set initially by EB) the power management system will automatically switched on. Power will be supplied to only the basic necessary equipment (as stated in the priority list) power to other load will be stopped so that huge amount of power can be saved without power cut.
In our project, this is achieved using NS2 software and using ZIGBEE. Whenever generation falls below the particular value, then the load will be automatically switched off based on priority. And it can also be done through an interrupt. Through ZIGBEE command the interrupt will be sent to microcontroller to cut the power to the particular load.
When microcontroller receiving the command, the relay will cut the power to the equipment. So the power will be saved.
In this project,the method to detect and to control the power theft is also stated. Other methods of power theft like damaging, by passing electrical power meter can also be detected and can be punished.
Man power can also be reduced. The power usage of the customer will be automatically updated in the EB station so there is no need of man power to take meter reading in the user side. After every two months the reading will be automatically resetted.

POWER QUALITY IMPROVEMENT IN ELECTRICAL RAILWAY POWER SYSTEM
This document discusses power quality improvement in electrical railway power systems. It describes a system that provides continuous power factor correction without manually loading capacitor banks. The system uses a piecewise-polynomial analog computer to compute transistor on-times based on power factor control and peak current limiting functions. It initiates conduction cycles when the inductor current reaches zero and terminates it after the computed on-time. This improves the power factor and reduces reactive power charges on electricity bills. The system aims to increase the power factor to over 0.95 in a cost-effective manner to improve efficiency and reduce costs.
major project ppt 27-4-16
This document discusses several techniques to reduce cogging torque in permanent magnet motors, which is an undesirable effect that prevents smooth rotor rotation. It describes classical and innovative techniques to minimize cogging torque through varying motor geometry while maintaining running torque. Some techniques discussed are skewing stator/magnets, fractional slots per pole, modulating drive current, and using optinet with magnets. Several industrial applications of cogging torque control are mentioned, like conveyor belts, CNC machines, and motorized vehicle braking. The document provides theoretical and practical justification for different cogging torque reduction techniques.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
