The working environment of construction machinery is harsh, and some operations are highly repetitive. realization intelligent helps to improve economic efficiency promote industrial development. Construction different from ordinary passenger vehicles. Aiming at the fact that existing environmental perception data set cannot be directly applied machinery, this paper establishes corresponding in...

I propose to consider the question, "Can machines think?" This should begin with definitions of the meaning of the terms "machine" and "think." The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words "machine" and "think" are to be found by examining how they are commonly used it is difficult to...

This article mainly studies automatic navigation control methods for agricultural machinery. The navigation system takes RTK-DGPS and inertial measurement unit as positioning sensors. The preview control mode was researched for curve path tracking. The preview control model is to determine the aiming point and calculate the lateral deviation. Automatic turning was realized by fuzzy control meth...

This study investigated the status of mechanized power and self-propelled rice cultivation machinery in Guilan Province in northern Iran. The raw data was obtained from 2013 statistics of the Agricultural Jihad Organization of Guilan province. Power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

Rotating machinery is the most common machinery in industry. The root of the faults in rotating machinery is often faulty rolling element bearings. This paper presents a technique using optimized artificial neural network by the Bees Algorithm for automated diagnosis of localized faults in rolling element bearings. The inputs of this technique are a number of features (maximum likelihood estima...

Gas foil bearing has been widely used in high-speed turbo machinery due to its oil-free, wide temperature range, low cost, high adaptability, stability and environmental friendliness. In this paper, state-of-the-art investigations of gas bearings are reviewed, mainly on the development China. After decades development, progress achieved field Small-scale applications have realized a variety mac...

We use an international dataset on 5-min interval intraday data covering nine leading markets and regions to construct measures of realized volatility, jumps, skewness, kurtosis returns Real Estate Investment Trusts (REITs) over the daily period September 2008 August 2020. study out-of-sample predictive value skewness for volatility above where we also differentiate between “good” “bad” volatil...
