We propose a new DDQ testing signature, the graphical DDQ signature. We discovered that noise, in the entire set of current measurements for a chip, is a vastly superior feature for classifying chips as good or bad, compared to present methods. The measured DDQ current as a function of vectors is defined here as the signature. We examine the shape of the waveform defined by the total set of the...

Increasing concerns about the environmental impacts of herbicides, the development of herbicide-resistant weeds, and the need to carefully weigh costs and benefits have led to greater interest in developing rational, economical, and sustainable approaches to weed management (O'Donovan 1996). In addition, greater emphasis on post-emergence applied herbicides such as glyphosate has allowed for mo...

Yields of four soybean cultivars were measured for 4 years in a field infested with Heterodera glycines race 3 and in a field infested with H. glycines race 14. Cultivars included Hutcheson (susceptible to both races), Deltapine 415 (resistant to race 3 and susceptible to race 14), Asgrow 5979 (resistant to both races), and Harwig (resistant to both races as well as most other known races of H....

The measured IDDQ current as a function of vectors is defined here as the IDDQ signature of a chip. We examined the IDDQ signatures of a large number of SEMATECH chips that have been classified us good or bud by a combined decision from functional, delay and scan tests. We find that a single IDDQ threshold, whether absolute or differential, cannot separate good/bud chips with any desirable accu...

in order to study the effects of wild mustard density on grain yield and yield components of canola cv. hyola 401 under different rates of nitrogen fertilizer, a field experiment was conducted in 2011-2012. the layout was split-plot in a completely randomized block design and three replications. main-plots included four levels of nitrogen (0, 70, 140 and 210 kg ha-1) and sub-plots consisted of ...
