Abstract: Engineering metrology is  the application of measurement science to manufacturing processes . It involves the use of measurement to assess the quality of manufactured components, calibrate measuring instruments, and ensure that products are made to metrological specifications.   Here are some key aspects of engineering metrology: Quality control Quality control engineers are responsible for ensuring that manufacturing meets metrological specifications. They must be familiar with measurement basics, standards, tolerances, and the limitations of measuring instruments.   Cost It can be expensive to comply with metrological specifications after a product has been manufactured.   Measurement accuracy Metrology is the science of high accuracy measurement. It involves establishing, reproducing, and conserving units of measurement and their standards.   Measurement processes Metrology covers a wide range of measurement processes, met...

A comprehensive book on Engineering Metrology and Measurements would typically include the following key content areas, progressing from foundational principles to advanced techniques and applications: Part 1: Fundamentals of Metrology Introduction to Engineering Metrology: Definition and scope of metrology Importance in manufacturing and quality control Basic measurement systems and their components (measurand, measuring instrument, scale, error) Units and Standards of Measurement: International System of Units (SI) Primary and secondary standards Traceability concept Measurement Errors and Uncertainties: Types of errors (random, systematic, gross) Error analysis and propagation Uncertainty calculation and expression Limits, Fits, and Tolerances: Basic concepts of limits, fits, and tolerances Tolerance zones and their application in design Geometric tolerances (straightness, flatness, parallelism) Part 2: Linear and Angular Measurements Linear Measurement Techniques: Verni...

Abstract: Ethical issues related to the Internet of Things (IoT) primarily center around data privacy, where personal information collected by connected devices could be misused, with examples like a smart home system collecting excessive data on residents' daily routines without their informed consent, potentially leading to privacy violations.  Key IoT ethical issues with examples: Data Privacy: A smart wearable device collecting health data without clear user consent on how that data is stored and used.  Informed Consent: A smart thermostat automatically adjusting temperature based on user presence without explicit permission to access location data.  Surveillance and Monitoring: Security cameras in public spaces potentially being used for excessive surveillance beyond their intended purpose.  Algorithmic Bias: A facial recognition system disproportionately identifying individuals from certain demographics due to biased training data.  Lack of Tra...
