This paper deals with a levelling machine for a seedling bed of a rice plant, which is a labor saving device in agricultural work.In order to make the seedling bed flat, the levelling machine vibrates by rotary motion of an eccentric rotor and presses the ground by the base plate of the machine.It is found that at a specific rotating speed, the mac
Road segmentation is an important task in the field of semantic segmentation, and the Deeplabv3+ algorithm, which is commonly used for road segmentation, has shortcomings, such as numerous parameters and a tendency to lose detailed information.Therefore, this paper proposes DCN-Deeplabv3+, an improved road segmentation algorithm with dual attention
An assortment of 10 winter wheat cultivars was tested for specific effects on weed suppression.Furthermore cultivar specific effects of weed infestation and weed control measures on the crop yield were investigated.Two trial series conducted from 2005 to 2010 demonstrated a wide cultivar specific range of shading capacity and weed suppression.Light
The effect of temperature, time and rotation speed of FT-GTL process water on the corrosion rate of API X-120 carbon steel was investigated.Electrochemical impedance spectroscopy and potentiodynamic polarization techniques were used to determine the Granola carbon steel corrosion rate under temperatures ranging from 293 to 323 K and rotation speed
The use of bleaching agent has increased as the result of increasing of paper consumption.The conventional bleaching agent that commonly used is material containing of chlorine.This material is not environmentally friendly and should be replaced by environmentally benign chemical, such as H2O2.About 40 gram of dry Akasia pulp was mixed with 600 ml
