Cranes are traditionally controlled by operators who present on-site. While this operation mode is still common nowadays, a significant amount of progress has been made to move away from their cranes, so that they would not be exposed hazardous situations may occur in workplace. Despite its apparent benefits, remote major challenge does exist on-site operation, i.e., the information could recei...

The research at University College London School of Medicine (UCLSM) is supported by the Wellcome Trust, Action Research, the Special Trustees of University College Hospital, and the Muscular Dystrophy Group of Great Britain. The studies have been carried out with the assistance of Dr. P. S. Tofts, Mr. D. Delpy and Mr. A. Chu of the Department of Medical Physics (UCLSM), and Mr. N.Taylor of Kin...

System-initiated digressive proposals may be used to introduce new and unexpected information into automated telephone services. These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller’s intended activity. In human–human conversation, interruptions are considered to be speech acts which intrinsi...

We examined the response of nesting greater sandhill cranes (Grus canadensis tabida) to research-related activities at Grays Lake, Idaho, during 1997–2000. Data were collected on >500 crane nests from 53 fields that were exposed to variable levels of research activity, from fields subjected to only periodic searches for and monitoring of crane nests (crane-only fields) to fields subjected to pe...

The Black-necked Crane Grus nigricollis is a globally vulnerable species whose food is the factor determining its long-term survival. Understanding dietary habits, food preferences, and related factors will facilitate the development of effective conservation plans for the protection of this vulnerable species. For this purpose, we used video recordings and sampling of food availability to exam...

In 1981, Paris and Wilkie [28] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that some specially formulated axiomizations for IΣ0 can evade the Herbrandized version of the Second Incompleteness Theorem.

We propose control methodology of two stacker cranes to avoid collisions in an automated storage/retrieval system including the constraint on trajectories caused by dynamics as shown in Fig. 1. In the automated storage/retrieval system environment, there are three problems: constraint on trajectories caused by dynamics (e.g., vibration control), safety in the case of an emergency stop, and prac...

We propose a new shipboard crane configuration for offloading cargo in open seas. We show that the “Maryland Rigging” crane of ship’s configuration, used in association with a friction control mechanism, provides a very effective method for reducing load pendulation caused by the motion of the crane in the roll direction. The effectiveness of the control technique is obtained by comparing the p...

Much of the previous research on anti-predation vigilance in groups has assumed independent scanning for threats among group members. Alternative patterns that are based on monitoring the vigilance levels of companions can also be adaptive. Coordination of vigilance, in which foragers avoid scanning at the same time as others, should decrease the odds that no group member is alert. Synchronisat...

A crane is the type of machine mainly used for handling heavy loads in different industry branches: metallurgy, paper and cement industry. By the construction, cranes are divided into the overhead and gantry cranes. An overhead crane, also known as a bridge crane, is a type of crane where the hook and line mechanism runs along a horizontal beam that itself travels on the two widely separated ra...
