WaveHit: The First Smart Impulse Hammer for Fully Automatic Impact Testing,mers. The internal calculation of pulse describes parameters such as the pulse height, pulse width and frequency range of the excitation or if the single hit is reached for autonomous quality assurance. Single hits are possible with position changes of the structure or the hammer in impact mode. Inevanescent 发表于 2025-3-23 23:59:09

Application of Smartphones in Pavement Deterioration Identification Using Artificial Neural Networkeen different pavement deterioration types. ANN was then used for classification. The training techniques were Patternnet, Learning Vector Quantization 1 (LVQ1), and LVQ2 algorithms and their combination, i.e., being first trained using one of these techniques and being again trained using another t合群 发表于 2025-3-24 07:20:30

Basic Vibration Analysis in a Laboratory Classroom Using Virtual Instruments,ing options. In this manner, the students are exposed to how each of these parameters, as well as the impact type and location, influences the signal captured and the resulting natural frequencies observed. The oscilloscope is used to capture the accelerometer signal for a relatively short period of
