Silent data corruption (SDC), sometimes called bit rot or silent data errors (SDEs), refers to errors in data that are not detected by standard error-checking mechanisms, leading to potentially significant data loss or incorrect calculations. SDCs can lead to inaccurate training, incorrect predictions, and unreliable performance. Detecting SDC requires specialized techniques and tools. SDCs can be transient or random.

Multi-sensor calibration of advanced driver assistance systems (ADAS) in autonomous vehicles ensures accurate data fusion by aligning various sensors (like cameras, LiDAR, and radar) into a unified coordinate system, enabling precise perception and localization. This article reviews the types and techniques of multi-sensor calibration of ADAS. ADAS sensor calibration uses a combination of intrinsic considerations for individual sensors and extrinsic system-level factors.

Rare earth elements (REEs) are important for society because they enhance the performance of a wide range of green energy, industrial, medical, aerospace, and consumer devices. They are rare because, while not uncommon, they are widely dispersed in the Earth’s crust and not generally found in high concentrations. That makes their extraction difficult and expensive.

Negative feedback can create a control system where the output of a process is used to counteract any deviations from a desired set point, effectively “correcting” the system, bringing it back to equilibrium, and maintaining stable operation. It’s used in a variety of applications, including voltage regulation, temperature controllers, audio amplifiers, and operational amplifiers.

Tools used for calibrating sensors range from basic multimeters and multi-product calibrators to application-specific tools, like pressure calibrators, calibration baths, and infrared blackbody calibrators, depending on the type of sensor and the measurement requirements. As sensors get more sophisticated and precise, so do the tools used to calibrate them. Sensors require calibration to deliver consistent accuracy.

Although improving a sensor’s actual performance is not usually possible, with proper selection, system design, and integration, improving sensor performance at the system level is very possible. Tools available for sensor performance optimization include selection, placement, operation, and signal conditioning/processing. It begins by selecting a sensor with the appropriate range, resolution, sensitivity, accuracy, response time, and other performance specifications.

Maxwell’s equations are fundamental tools for electric and magnetic fields, while Maxwell’s relations focus on thermodynamic quantities like temperature, pressure, volume, and entropy. For more on Maxwell’s equations, see “What are the fundamentals of Maxwell’s equations and how do they relate to TENGs?”Maxwell’s relations give designers a powerful tool for analyzing thermodynamic systems like internal combustion engines or data center cooling.

A vertical cavity surface-emitting laser (VCSEL) relies on a three-dimensional (3D) structure for light emission. A photonic crystal surface-emitting laser (PCSEL) incorporates a 2D photonic crystal (PhC) layer to manipulate light emission. Those structural differences lead to different performance and application possibilities. An obvious difference between the various types of semiconductor lasers is the beam patterns.
