Spraying pesticides using row alignment in the maize seedling stage can effectively improve pesticide utilization and protect ecological environment. Therefore, this study extracts a guidance line for crops machine vision develops an automatic row-oriented control system based on high-clearance sprayer. First, feature points of crop rows are extracted vertical projection method. Second, candida...

Measurements and numerical studies of the self-induced magnetic field effects of twodimensional niobium Josephson junction arrays have been performed. Experiments focus on the dc electrical properties of these arrays and can be classified into four regimes: the superconducting state, flow-flow regime, the row-switching state, and novel resonance steps. We find that self-field effects can be mod...

OBJECTIVE Comparative evaluation of ground-glass opacity using conventional high-resolution computed tomography technique and volumetric computed tomography by 64-row multi-slice scanner, verifying advantage of volumetric acquisition and post-processing technique allowed by 64-row CT scanner. METHODS Thirty-four patients, in which was assessed ground-glass opacity pattern by previous high-res...

In order to evaluate the effect of row and plant spacings on the yield and yield components of three cultivars of forge sorghum, a field experiment was conducted in Isfahan University of Technology, Lavark, during spring, 2001. Experimental design was a split-factorial with three replications. Main plots consisted of three row spacings (45, 60, 75 cm) and subplots were combinations of three cul...

Regular 2D arrays of multiple types of nanocomponents were constructed by self-assembly to DNA scaffolding with alternating rows of sequence-encoded hybridization sites. Different-sized Au particles coated with DNA complementary to one of the sites were bound to the scaffolding, producing alternating rows of the two nanocomponents with a 32-nm inter-row spacing. These results demonstrate the po...

The objective of the study was to evaluate performance a vacuum single-seed planter in field conditions optimize some operating parameters maize production. Three forward speed tractor (4.0, 5.4 and 7.9 km h-1) five target seed spacing (102, 147, 195, 247 309 mm) were evaluated by examining mean spacing, coefficient precision miss index, multiple quality feed sowing depth, deviation from row (i...

Rooftop buildings, mountain terrains, rivers, and lake beds may be oriented at different azimuths other than due south (in the northern hemisphere), on which photovoltaic (PV) systems installed. The present study presents a comprehensive point of view relation between inter-row spacing shading in multiple-row collectors PV fields; it analytically formulates associated losses for deployed any az...
