- Course objectives
- The course will provide students with basic knowledge of the physical quantities determining the physical environment and methods of measurement and measurement principles applicable to the measurement. The course is divided into two parts. This part I includes physical theory, physical methods and measurement principles that are relevant to the issue of measurement noise, vibration, and vibration. Emphasis is placed on the physical nature of the problem and the application of physical theory to the measurement noise, vibration, and vibration and the harmful effects of exposure to mechanical systems and biological objects and physical protection principles.
