A remnant fertilizer monitoring system utilizing three-dimensional (3D) reconstruction is proposed to detect the amount of remaining fertilizer in the applicator’s tank. Bench tests are carried out to compare the performance of four algorithms to estimate the remnant fertilizer amount:...

In order to investigate the influence of minor Ru on electrochemical behavior and structural characteristics of passive film on the surface of Ti-6Al-4V alloy in various oil & gas exploration conditions, electrochemical techniques, XPS, SEM and corrosion simulation tests were carried out, and...

Permeability is a key parameter for gas recovery from marine hydrate reservoirs. In this study, two kinds of BZ02 and BZ04 glass beads provided skeleton structure for methane hydrate synthesis in pressure vessel. Based on the observation of Scanning Electron Microscopy (SEM), the glass beads in...

Porous CoAl 3 intermetallic is a candidate material in the field of catalytic and filtration due to its high porosity, good thermostability and quasicrystal structure. However, its rapid and reliable preparation are still a challenge, and the high-temperature antioxidant mechanism need to be...

This paper develops a dynamic general equilibrium model with heterogeneous firms that face search complementarities in the formation of vendor contracts. Search complementarities amplify small differences in productivity among firms. Market concentration fosters monopsony power in the labor...

When adjudicating multi-billion-dollar cases involving the licensing of patents covering industry standards such as Wi-Fi and 5G (standards-essential patents or SEPs), courts around the world have increasingly issued injunctions preventing one party from pursuing parallel litigation in another...
