It provides details on the principles and workings of various force measurement devices: - Scales and balances measure force by balancing an unknown force against a known gravitational force using standard masses. Unequal arm beam balances relate the length of the beam to the measured force. - Elastic force meters measure the deflection of an elastic member like a spring when an unknown force is applied and relate it to the measured force. - Load cells translate an applied force into a fluid pressure that is then measured, allowing highly accurate force measurement. Hydraulic and pneumatic load cells work on

Comparators

GAURAVBHARDWAJ160

1) Comparators are used to quickly and consistently measure dimensional variations in mass produced parts by comparing parts to a master part. 2) A comparator works by first adjusting to zero using a gauge block, then placing the workpiece to determine the dimensional difference. 3) All comparators have a sensing device, magnifying system, and display scale to sense input, amplify signals, and provide readable output.

Angular measurement

GAURAVBHARDWAJ160

This document provides information on various tools used for angular measurement in engineering. It discusses simple protractors, vernier bevel protractors, sine bars, and angle gauges. The vernier bevel protractor allows measuring angles to the nearest minute using a vernier scale. It has a stock, dial, blade, and locking screws. A sine bar measures angles based on trigonometric relationships between the bar length and height of slip gauges. It requires accessories and is limited to angles above 45 degrees. Angle gauges can be combined in different configurations to measure angles from 0 to 90 degrees and minutes.

Linear measurement

GAURAVBHARDWAJ160

This document discusses various linear measurement instruments categorized as either non-precision or precision tools. Non-precision tools like steel rules and calipers provide measurements to the nearest line on the tool. Precision tools like vernier calipers, micrometers, and slip gauges provide highly accurate measurements. The document describes the parts and operating principles of vernier calipers, micrometers, height gauges, and slip gauges. It also provides formulas for calculating measurements and measurement errors using these precision tools.

Line and end standard

GAURAVBHARDWAJ160

Line standards and end standards are two categories of instruments used to directly measure linear dimensions. A line standard measures the distance between the centers of two engraved lines, such as a ruler. It allows for quick measurements over a wide range but lacks precision due to line thickness and susceptibility to parallax errors. An end standard measures the distance between two parallel flat surfaces, such as slip gauges or a micrometer anvil. It provides highly accurate measurements of close tolerances but is more time-consuming and the faces can wear over time. End standards have a built-in datum for alignment and are not subject to parallax.

This document describes how to use a Vernier caliper to take precise measurements and calculate percentage error. It explains the parts of a Vernier caliper including internal and external jaws, depth rod, and main and Vernier scales. It provides the formula for calculating least count and how to determine measurements based on main scale reading, Vernier scale reading, and least count. The document also discusses types of errors in Vernier calipers and the procedure for taking accurate measurements and calculating percentage error.

Errors in measurement

GAURAVBHARDWAJ160

This document discusses errors in measurement and different types of errors. It explains that there are five main elements that can cause errors: standards, work pieces, instruments, persons, and environment. There are three types of errors: systematic errors, which occur due to imperfections and are of fixed magnitude; random errors, which occur irregularly; and statistical analysis can be used to analyze random errors through calculations of mean, range, deviation, and standard deviation. Systematic errors include instrumental errors from faulty instruments, environmental errors from external conditions, and observational errors from human factors like parallax.

Characteristics of Measuring instruments

GAURAVBHARDWAJ160

This document discusses the characteristics of measuring instruments, dividing them into static and dynamic characteristics. Static characteristics describe instruments that measure non-fluctuating quantities, and include scale range, accuracy, precision, error, calibration, resolution, threshold, sensitivity, repeatability, reproducibility, readability, linearity, drift, and hysteresis. Dynamic characteristics apply to instruments that measure fluctuating quantities over time, and consist of speed of response, measuring lag, fidelity, and overshoot.

Introduction to measurement

GAURAVBHARDWAJ160

Embedded machine learning-based road conditions and driving behavior monitoring

IJECEIAES

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.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

gerogepatton

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%.
