Record drilling depth struck in Greenland

A Fast Inspection of Tool Electrode and Drilling Depth in EDM Drilling by Detection Line Algorithm

The purpose of this study was to develop a novel measurement method using a machine vision system. Besides using image processing techniques, the proposed system employs a detection line algorithm that detects the tool electrode length and drilling depth of a workpiece accurately and effectively. Different boundaries of areas on the tool electrode are defined: a baseline between base and normal...

David Aronson : STRUCK BY SCIENCE

technical analysis for 40 years and was a true believer. However, his faith in the effectiveness of technical analysis was shaken in the summer of 2000, just after the technology bubble burst. At the time, Aronson, 61, worked as a proprietary trader for Spear, Leeds, and Kellogg and had been profitable for four years. He used standard technical analysis techniques — interpreting classic chart p...

The role of albedo and accumulation in the 2010 melting record in Greenland

Analyses of remote sensing data, surface observations and output from a regional atmosphere model point to new records in 2010 for surface melt and albedo, runoff, the number of days when bare ice is exposed and surface mass balance of the Greenland ice sheet, especially over its west and southwest regions. Early melt onset in spring, triggered by above-normal near-surface air temperatures, con...
