This paper pertains to advanced automation of the load transfer process using overhead cranes. Overhead cranes are widely used in various areas of industry, including manufacturing, construction, shipping, etc. Load transfer operations using overhead cranes have to be performed fast and safely. As such, these operations are handled by expert operators however, the demand for an automatic consis...
We present simulations, without electrodynamical assumptions, of Bsx, y, Hstdd, MsHstdd, and JcsHstdd in hard superconductors for a variety of twin-boundary pinning potential parameters, and for a range of values of the density and strength of the pinning sites. We numerically solve the overdamped equations of motion of up to 10 flux-gradient-driven vortices which can be temporarily trapped at ...
A new layout of the U-shaped automated terminal is more convenient to connect between and railway. In this study, a sort cluster scheduling method for multiple equipment yard railway proposed. The innovation points are as follows: (1) Considering that rail gantry crane (RGC), intelligent guided vehicle (IGV), double cantilever (DCRC) usually work in groups, they grouped cluster-scheduled. (2) h...
The mobile crane simulator is a project sponsored by Employment and Vocational Training Administration, Council of Labor Affair, Executive Yuan, Taiwan, to build a safe device for training and licensing. This paper presents the principle and mechanism to build a high-fidelity interactive visual simulator on a cluster of PCs. The implemented mobile crane simulator uses the peer-to-peer architect...
In this paper, a new fuzzy anti-swing control scheme is proposed for a three-dimensional overhead crane. The proposed control consists of a position servo control and a fuzzy-logic control. The position servo control is used to control crane position and rope length, and the fuzzy-logic control is used to suppress load swing. The proposed control guarantees accurate control of crane position an...
Quay crane allocation is one of the most important scheduling plans in the container terminal. A large of production data is stored in the database of the terminal. This paper utilizes the method of data mining to analyze the problem of quay crane allocation by using these data. From the mining, valuable information has been gotten from the database. The paper chooses the fuzzy cmeans cluster a...
The complex, dynamic, and continually changing nature of construction work has been recognized as an important contributor to the high rates of injuries and fatalities in the industry. Cranes are a central component of many construction operations and are associated with a large fraction of construction deaths; in fact, estimates suggest that cranes are involved in up to one-third of all constr...
Crane Division, Naval Surface Warfare Center, Crane Crane's comprehensive pollution prevention program emphasizes planning, employee education, innovation and incentives. One of Crane's primary goals is to move the facility from a pollution control mindset to a pollution prevention ethic through its Corporate Environmental Policy Statement, environmental management system and educational tools ...
The Dynamics characteristic of Tower Crane is complicated under the wind excitation which complicates the wind-induced vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite element method and Virtual Excitation Method. The pulsating wind loads are changed into multiple-point correlation stationary excitation. This papers uses Davenpor...
Large-lot exurban landscapes could incorporate ecological design in order to contribute ecosystem services. In our study, we use a survey of 126 Southeast Michigan homeowners to examine respondents’ stated preferences for residential yard images, and compare those with reported current use and management of their actual yards. We found that stated preferences are not necessarily related to actu...
