This research was designed and implemented to determine the effect of different irrigation regimes on the grain yield, dry matter, tiller number per unit area, degree of maturity, panicle harvest index, percentage of leaf rolling, day to 50% flowering, and the physiological maturity of rice genotypes, using a split plot randomized complete block design in two years (2014 and 2015). Four irrigat...

Yield forecasting is critical to a semiconductor manufacturing factory. To further enhance the effectiveness of semiconductor yield forecasting, a fuzzy-neural approach with collaboration mechanisms is proposed in this study. The proposed methodology is modified from Chen and Lin’s approach by incorporating two collaboration mechanisms: favoring mechanism and disfavoring mechanism. The former h...

To realize tomato growth period monitoring and yield prediction of cultivation, our study proposes a visual object tracking network called YOLO-deepsort to identify count tomatoes in different periods. Based on the YOLOv5s model, model uses shufflenetv2, combined with CBAM attention mechanism, compress size from algorithm level. In neck part network, BiFPN multi-scale fusion structure is used i...

the present paper compares full kinetics mechanisms in numerical modelling of porous radiant burners (prb), with their reduced forms. the two most frequently used mechanisms of methane combustion (gri3.0 and miller) were selected and their effects were examined on temperature, species concentration, burning speed, and pollutant emission. while the findings of numerical simulation of prb show fi...

The iron(IV) nitrido complex PhB(MesIm)3Fe≡N reacts with 1,3-cyclohexadiene to yield the iron(II) pyrrolide complex PhB(MesIm)3Fe(η(5)-C4H4N) in high yield. The mechanism of product formation is proposed to involve sequential [4 + 1] cycloaddition and retro Diels-Alder reactions. Surprisingly, reaction with 1,4-cyclohexadiene yields the same iron-containing product, albeit in substantially lowe...

Background: Iodine-123 (123I) is regarded as one of the best radionuclides for in vivo medical studies using single-photon emission computed tomography (SPECT) due to its suitable physical property. Materials and Methods: To design a new system in order to replace cryogenically solidified xenon target by the gas one, some necessary calculations are needed to be done such as finding the excitati...

Successful implementation of socio-economic projects depends on the degree of planners’ awareness of farmers’ risk coefficient. Because agriculture is a risky activity, knowledge about the farmers’ attitudes toward risk in each area is essential. This research investigated the farmers’ risk behavior in Homayjan district in Sepidan township. Cross-section and time series data were collected from...

stem reserve remobilization is very important to keep the grain yield in wheat under terminal drought but the importance of this mechanism is unclear under terminal salinity. in this research stem reserve remobilization under terminal salinity were studied in greenhouse on four genotypes no14 and no49, different in remobilization, and bam as salt-tolerant and ghods as salt-sensitive cultivars. ...

We describe a nearly explicit chemical mechanism for isoprene photooxidation guided by chamber studies that include time-resolved observation of an extensive suite of volatile compounds. We provide new constraints on the chemistry of the poorly-understood isoprene δ-hydroxy channels, which account for more than one third of the total isoprene carbon flux and a larger fraction of the nitrate yie...

Thin coal seam mining is a development direction to solve the problem of energy supply at this stage, which cannot be realized by small working space, low automation, and drilling deviation. In paper, nonlinear adaptive backstepping controller based on disturbance observer proposed used auger for position tracking control achieve directional drilling. Firstly, dynamic model deflection mechanism...
