The use of multifunctional structures (MFSs)—which integrate a wide array of functional capabilities such as load-bearing [1], electric [2], and thermal-conductivity [3] capacities in one structure—can prevent the need for most bolted mechanical interfaces and reduce the volume of the total system. Thus, MFSs offer … Witryna10 lut 2024 · Real-Time Facial Recognition with Python. Cameron R. Wolfe. in.
