In practical applications, an electronic compass composed of a three-axis magnetometer and a three-axis accelerometer is often due to the strong magnetic field interference of the copyright, which makes the magnetometer unable to accurately calculate the heading, and even causes the electronic compass to fail.This problem puts forward more stringen

The presented study summarizes the results concerning the effects of cultivation of Douglas-fir (Pseudotsuga menziesii (Mirbel) Franco) in the Czech Republic.It focuses on more recent results, published especially in the last decades, it includes also older relevant data.It describes the intensity of production as well as non-production forest func

The electrochemical micromanufacturing process, as a key micromanufacturing technology, plays an important role in diverse industries.In this Stationery paper, polydimethylsiloxane (PDMS) is employed as a mask in the electrochemical micromanufacture of microstructures because of its chemical resistance, low cost, flexibility, and high molding capab
