Present contour measuring systems are reviewed and discussed in general, and capabilities of an over-all system are summarized. Problem areas are discussed and a best approach to future design of systems is offered.

Information Science and Electronic Engineering is a collection of contributions drawn from the International Conference of Electronic Engineering and Information Science (ICEEIS 2016) held January 4-5, 2016 in Harbin, China. The papers in this proceedings volume cover various topics, including: - Electronic Engineering - Information Science and Information Technologies - Computational Mathematics and Data Mining - Image Processing and Computer Vision - Communication and Signal Processing - Control and Automation of Mechatronics - Methods, Devices and Systems for Measurement and Monitoring - Engineering of Weapon Systems - Mechanical Engineering and Material Science - Technologies of Processing. The content of this proceedings volume will be of interest to professionals and academics in the fields of Electronic Engineering, Computer Science and Mechanical Engineering.

Meeting the needs of the manufacturing and service sectors of contemporary industry, this volume is concerned with the human factors, ergonomics, and safety issues related to the design of products, processes, and systems, as well as the operation and management of business enterprises. This book will be of special value to researchers and practitioners involved in the design of products, processes, systems, and services, which are marketed and utilized by a variety of organizations around the world.

The paper presents experimentally determined contours at initial buckling for an aluminum right circular cylindrical shell of 3.35 inches of diameter and 0.0025 inches wall thickness loaded in axial compression. It shows that when the buckle amplitude is only 2.8 times the wall thickness there is strong evidence of plastic deformations. (Author).
