Land leveling is one of the most important steps in soil preparation and cultivation. Although land leveling with machines requires considerable amount of energy, it delivers a suitable surface slope with minimal soil deterioration as well as damage to plants and other organisms in the soil. Notwithstanding, in recent years researchers have tried to reduce fossil fuel consumption and its delete...

Volatility is the primary measure of risk in modern finance and volatility estimation and inference has attracted substantial attention in the recent financial econometric literature, especially in high-frequency analyses. High-frequency prices carry a significant amount of noise. Therefore, there are two volatility components embedded in the returns constructed using high frequency prices: the...

This study was conducted to compare the methods of seed bedpreparation in rangelands of Khash region in Sistan and Baluchestan province inIran. A split plot design was conducted based on Randomized complete blockdesign with three replications in 1999. Five seed bed preparation methods wereused as main plot as: 1) Seed sown by passing livestock. 2) Seed sown machinery.3) Seeds sown as drilled in...

Novel and practical low-temperature 3D printing technology composed of a machine optimized parameters was successfully developed. Under environment 0–−20 °C, poly (vinyl alcohol) (PVA) matrix hydrogels including PVA-sodium lignosulphonate (PVA-LS) hydrogel carboxymethylcellulose (PVA-CMC) exhibited specific rheology properties, building theoretical printable bases. The self-made realized machin...

F orecasting the volatility of a financial asset has wide implications in finance. Conditional variance extracted from the GARCH framework could be a suitable proxy of financial asset volatility. Option pricing, portfolio optimization, and risk management are examples of implications of conditional variance forecasting. One of the most recent methods of volatility forecasting is Real...
