Against the background of data explosion and cloud computing, this paper investigates a branch of the cloud computing technology which is known as VDI (virtual desktop infrastructure). Users can access data and information via cloud desktops with the endpoint devices. The paper studies OpenStack - a famous open-source cloud platform which has been widely used, and introduces a secure, optimized and...
Mismatch is an important quality evaluation standard in Tailor welded blanks. The control of mismatch, especially for thinner blanks, is a difficult technique in tailored blank laser welding process. In this paper, the production and control of mismatch is studied based on a tailored blank laser welding system. The origins of the mismatch are obtained after numbers of experiments: the deformation...
This paper introduces the research on error modeling of a five-axis laser processing robot which has three linear axes and two rotational axes. The error models are developed based on vector/matrix notion. Homogeneous coordinate transformations are employed to represent the ideal and real linear\rotation transformations of the five-axis laser processing robot by considering small angular approximation...
