Mapping of Cone Index for Precision Tillage [PDF]
Journal of Biosystems Engineering, 2005 Precision tillage is designed to till lands variably according to their firmness. Therefore, it is necessary to measure soil firmness in fields and present it in a form with which the variable tillage on be performed. Such forms may be classified into two categories: sensor-based and map-based forms.

Cone penetration index for soil behaviour type prediction
Scientific Reports, 2022 Several approaches have been proposed to classify soil types using both cone and piezocone penetration tests. The chart relating the normalized cone resistance (Q tn ) and the friction ratio (F r ) has proven to be the most reliable method.

Dirac-like cone-based electromagnetic zero-index metamaterials [PDF]
Light: Science & Applications, 2021 Metamaterials with a Dirac-like cone dispersion at the center of the Brillouin zone behave like an isotropic and impedance-matched zero refractive index material at the Dirac-point frequency.

An overview of methods to convert cone index to bevameter parameters
Journal of Terramechanics, 2020 Abstract This paper reviews experimental methods for the conversion of cone index measurements to bevameter parameters in support of vehicle soil/tire/track interactions for two general soil types, sand and lean clay. The accurate prediction of traction, motion resistance, and sinkage of tire/tracks off-road requires estimates of soil strength ...

The Effect of Tillage Methods on some Soil Properties and Water Productivity of Two Sugar Beet Cultivars [PDF]
مجله آب و خاک, 2021 Introduction: North of Khuzestan province is one of the major areas for autumn sugar beet planting. Conventional tillage (CT) is widely practiced by sugar beet growers in this region. CT in sugar beet consists of burning wheat residue, using deep plowing
