Random errors are errors made by the person carrying out the measuring, and are usually down to timing incorrectly, or reading the instrument incorrectly. It is ...

Abstract: Nowadays, MEMS technologies have been widely developed in different areas of electronics. Many MEMS-devices such as inclinometers based on high-precision ...

Introduction Wearable sensor systems may be useful for measuring head-impact exposure. Here, we tested the validity of in-ear sensors developed to improve head coupling. Methods First, the sensor was ...

Abstract: During evaporation process for alumina production, various measuring instruments are inevitably affected by strongly alkaline and high-temperature ...
