Measurement systems analysis v1.1
Measurement systems analysis (MSA) is a scientific method used to analyze the validity and sources of variation in a measurement system. An MSA quantifies equipment variation, appraiser variation, and the total variation of a measurement system. It is used to validate measurement tools and processes, ensure consistent data collection, and identify areas for improvement like additional training or revised procedures.
Basic SPC Training
- Statistical process control (SPC) is a method for monitoring and controlling a process to ensure it operates at its full potential and produces conforming product. Variation exists in all processes and SPC helps distinguish between natural and uncontrolled variation.
- SPC was pioneered in the 1920s and applied during World War II to improve quality. Control charts are a key SPC tool used to monitor processes over time and identify factors causing non-random variation. The two main types are x-bar charts for variables and R charts for dispersion. Proper application of SPC can reduce waste and costs while improving customer satisfaction.

The document describes the DMAIC process for problem solving and process improvement. It consists of 5 phases: Define, Measure, Analyze, Improve, and Control. The Control phase involves implementing process controls, monitoring performance with tools like statistical process control (SPC) charts, and ensuring defects do not recur. The objective is to prevent problems and their root causes from reoccurring by documenting results, implementing controls, and selecting the appropriate control tools and activities based on the solution developed in prior phases.
Statistical Process Control & Control Chart
Statistical Process Control (SPC) uses control charts to monitor processes over time and identify sources of variation. Control charts graph key data metrics and establish control limits to determine whether the process is in a state of statistical control or if special causes are present. The benefits of SPC include early detection of quality issues, reduced waste, and improved process cycle times and customer satisfaction through a diminished likelihood of rework.
7 quality control tools
After World War II, Japan adopted quality as an economic strategy and selected seven statistical tools to analyze quality problems and drive continuous improvement. The seven tools - Pareto charts, cause-and-effect diagrams, histograms, control charts, scatter plots, check sheets, and flow charts - can identify up to 95% of issues. Each tool has a specific purpose, such as prioritizing problems with Pareto charts or identifying relationships between variables with scatter plots. Using these tools, Japanese companies were able to dramatically improve quality and economic performance.

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.

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.

A cause and effect diagram is “a fish-bone diagram that presents a systematic representation of the relationship between the effect (result) and affecting factors (causes).” Solving a problem in a scientific manner requires clarification of a cause and effect relationship, where the effect (e.g., the result of work) varies according to factors (e.g., facilities and machines used, method of work, workers, and materials and parts used). To obtain a good work result, we must identify the effects of various factors and develop measures to improve the result accordingly.
