Frequency multipliers are used in electronic devices to generate spectrally pure sinusoidal signals in the frequency range from a few to tens of GHz.The multipliers are used to multiply the frequency of highly stable but more low-frequency devices with the subsequent extraction of the necessary harmonics from the frequency spectrum of the received
Long-term structural health monitoring (SHM) plays an important role in the safety of public transport infrastructure such as bridges or tunnels and warns in the event of any emerging problem.This article describes development and testing of system based on fiber Bragg grating (FBG) sensors that can Adaptive Kitchen Tools detect changes in strain a
Tunnel face stability has received increasing research interest over the past few decades.However, computing time-efficient and safe three-dimensional solutions under seismic loading is still an unsolved problem, while case studies indicate that seismic loading can be one critical destabilizing factor affecting tunnel stability.The primary objectiv
The first steps of the conducting technique mean-Conducting warm-ups Salt and Pepper which entail the preparation and shaping of the conducting apparatus.Consequently, there are several types of exercises, such as releasing the arms, relaxing the muscles, but also those that help shape and perfect the conducting gesture.This study comprises not onl
