1 Spatial Optimization of Fertilizer Application by a Centrifugal Spreader
Fertilization practice using centrifugal spreaders generally consists in the mass flow rate regulation thanks to the simple mathematical relation D=Q.L.V/600 where Q is the prescribed fertilization rate, L the working width and V the tractor speed. Modern machines equipped with DPAE device can thereby continuously control the mass flow rate with respect to the working width that is in most case...
متن کاملHigh Speed Stereovision Setup for Position and Motion Estimation of Fertilizer Particles Leaving a Centrifugal Spreader
A 3D imaging technique using a high speed binocular stereovision system was developed in combination with corresponding image processing algorithms for accurate determination of the parameters of particles leaving the spinning disks of centrifugal fertilizer spreaders. Validation of the stereo-matching algorithm using a virtual 3D stereovision simulator indicated an error of less than 2 pixels ...
متن کاملFeed Gate Adaptation of a Spinner Spreader for Uniformity Control
Variable rate application of fertilisers with traditional spinner-type spreaders is known to suffer from spread pattern uniformity variability as a function of application rate. To demonstrate this variability, simulations using models from the literature were carried out for two cases: (1) a dual disc spreader with segment-type feed gates; and (2) a single disc spreader with conical feed gates...
متن کاملCentrifugal control in mammalian hearing.
1. Centrifugal control of many sensory systems is well established, notably in the gamma motorneuron of skeletal muscle stretch receptors. 2. Efferent (olivocochlear) innervation of the mammalian cochlea was first established through anatomical studies. Histological studies confirmed synaptic terminals in contact with hair cells and afferent dendrites. 3. Electrophysiology has elucidated the ce...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
