Greenland melting due equally to global warming, natural variation

2014-05-08 01:17:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: The rapid melting of Greenland glaciers is captured in the documentary "Chasing Ice." The retreat of the ice edge from one year to the next sends more water into the sea. Now University of Washington atmospheric scientists have estimated that up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable...

SMD NTC Thermistors offer stability with low R25 value variation.

2014-01-30 14:33:45| Industrial Newsroom - All News for Today

Providing precise measurements, NTCS....E3...SMT series experiences ±0.5% max variation in initial electrical resistance values at +25°C (R25) after 10,000 hr of operation over the full -40 to +125°C range. Non-standard R25 values are adapted to resistivity of thermistors' stable ceramic material and case dimensions, preserving original electrical properties throughout lifetime. Supplied in 0402, 0603, and 0805 case sizes, RoHS-compliant thermistors offer R25 values from 100–210 kΩ.

Parametric 3D CAD Software features direct variation modeling.

2013-11-06 14:29:39| Industrial Newsroom - All News for Today

With KOMPAS-3D v14, users can directly edit models in variation mode using geometrical and dimensioning constraints. Direct variation modeling makes it possible to modify 3D models without construction history, including those imported from other CAD systems. Program displays linear and angular values of numeric parameters on screen as users create and edit elements. Also, KOMPAS-3D v14 stores all revisions in model and allows users to recalculate geometry of models using tolerance fields. This story is related to the following:Modeling Software |

Odd field patterns help identify yield variation at plant level

2013-11-05 16:47:00| Corn & Soybean Digest

Learn plant by plant | Engineer/farmer finds 10-20 bushel improvement possible. When Bob Recker sees odd patterns in cornfields from the air as he flies across farmland in northeastern Iowa, he cant wait to land and investigate up close. As owner of Cedar Valley Innovation, Waterloo, Iowa, he uses digital and GPS technologies, along with well honed engineering analytical skills to identify yield-loss problems. read more
