Production management aims to maximize profit by increasing salable output while reducing the cost related with inspection, where inspection is defined as the measurement and quality assessment of items produced. This study is based on a semiconductor production line with consecutive deteriorating machines. Each machine is inspected via the items it produces and an inspection result triggers a ...

Sorghum (Sorghum bicolor L. (Moench)) is the third major cereal crop in Ethiopia in terms of area and production next to tef (Eragrostis tef) and maize (Zea mays). It is the major crop in drought stressed lowland areas that cover 66% of the total arable land in the country. Yield stability is one of the setbacks facing plant breeders in developing widely adapted varieties with superior yield. T...

the adequacy of the swat model in the estimation of runoff, sediment yield and nitrate loss in the gorganrood watershed was tested, using the existing spatial database as the primary data. the model was then executed for a 31-years’ time period. in combination with the swat model, the sequential uncertainty fitting program (swat-cup and sufi-2) was added used to calibrate and validate a hydrolo...

in this study, ice-glazing process of frozen shrimp by chitosan was applied to protect the frozen shrimp from undesirable chemical and physical changes. the effects of 2% chitosan solution glazing on quality of whole, raw and cooked (without head, tail and shell) shrimps stored at -18±2ºc for 6 months were investigated and compared with water glazing, sodium metabisulfite treatment control. gla...

in order to evaluate the competitive ability (ca) of canola cultivars against wild mustard, two experiments were conducted at the gorgan institute in iran during the 2005-2007 cropping seasons. the experimental factors were canola cultivars (1st year: zarfam, option500, hayola330, hayola401, talayh, rgs003 and sarigol; 2nd year: zarfam, hayola330, rgs003 and option500) and weed density (1st yea...

Monitoring crop condition and production estimates at the state and county level is of great interest to the U.S. Department of Agriculture. The National Agricultural Statistical Service (NASS) of the U.S. Department of Agriculture conducts field interviews with sampled farm operators and obtains crop cuttings to make crop yield estimates at regional and state levels. NASS needs supplemental sp...
