The position of the inertial sensors on the body, such as a user's hand [15], waist [16], pocket [17], and foot [18,19], has a significant influence on the accuracy, reliability, and usage of the PDRs. Moreover, due to advances in Micro Electro Mechanical Systems (MEMS) ...
In reflection mode, needed for materials deposited on top of surfaces or underneath them, a goniometer is required to align the sample surface with respect to the primary beam and to set the incidence angle. The incidence angle allows the penetration depth of the X-ray beam to be varied ...
AM, also known as 3-dimensional printing (3DP), creates the desired shape by adding material, preferably by layer- ing contoured layers on top of each other. The need for low cost, design flexibility and automated manufacturing processes in industry has triggered the development of FDM. ...
