From automation to Silicon Valley: the automation movement of the 1950s,Arnold Beckman,and William Shockley

Most studies mark the start of silicon electronics in Silicon Valley with William Shockley and Arnold Beckman’s creation of the Shockley Semiconductor Laboratory. This study details how the automation movement of the 1950s shaped the careers of both Shockley and Beckman, and formed an indispensible context for their creation of Shockley Semiconductor. Shockley was engaged in automation from the early 1950s, promoting his vision of an ‘automatic trainable robot’ to revolutionize manufacturing. Beckman was deeply involved in automation in the mid-1950s, orienting his company to key technologies for the ‘automatic factory:’ instrumentation and computers. Beckman and Shockley’s entrepreneurial involvements with electronics and automation led them to create Shockley Semiconductor to pursue silicon transistors in 1955.     

Mapping Submerged Archaeological Sites using Stereo‐Vision Photogrammetry

Creating photo‐mosaics and plans of submerged archaeological sites quickly, cost‐effectively and, most importantly, to a high level of geometric accuracy remains a huge challenge in underwater archaeology. This paper describes a system that takes geo‐referenced stereo imagery from a diver‐propelled platform and combines it with mapping techniques widely used in the field of robotic science to create high‐resolution 2D photo‐mosaics and detailed 3D textured models of submerged archaeological features. The system was field tested on the submerged Bronze Age town of Pavlopetri off the coast of Laconia, Greece, in 2010. This paper outlines the equipment used, data collection in the field, image processing and visualization methodology.
