Weed Infestation Identification Using Hierarchical Crowdsourcing
Weed infestation is a common problem in agriculture that adversely affects crop production. Given severe constraints on the budget of many landgrant universities due to the economic downturn, outreach services have taken a hit. To adapt to current economic climate without adversely affecting the quality of outreach program for weed management, we present a hierarchical system that uses image ca...
متن کاملEffect of tillage systems on weed infestation of durum wheat
Weed infestation of durum wheat was determined in the systems of conventional tillage(CT), reduced tillage (RT) and herbicide tillage (HT). Cultivations measures performed after theharvest of the previous crop included shallow ploughing (at a depth of 10-12 cm) and pre-winterploughing (25-30 cm) in the CT system; only field cultivation (10-15 cm) in the RT system; andspraying with glyphosate (R...
متن کاملStructure of weed communities occurring in crop rotation and monoculture of cereals
A strict field experiment with crops sown in crop rotation and monoculture wascarried out in the years 1988-2012 at the Experimental Station Uhrusk belonging tothe University of Life Sciences in Lublin, south-eastern Poland. The study wasaimed at evaluating the structure of weed communities occurring in crop rotationand monoculture of cereals. The highest weed density m-2 was determined inthe s...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولUsing Bayesian networks with rule extraction to infer the risk of weed infestation in a corn-crop
This paper describes the modeling of a weed infestation risk inference system that implements a collaborative inference scheme based on rules extracted from two Bayesian network classifiers. The first Bayesian classifier infers a categorical variable value for the weed–crop competitiveness using as input categorical variables for the total density of weeds and corresponding proportions of narro...
