Assessing the safety status of cranes is an important problem. To overcome the inaccuracies and misjudgments in such assessments, this work describes a safety assessment method for cranes that combines entropy and cumulative prospect theory. Firstly, the proposed method transforms the set of evaluation indices into an evaluation vector. Secondly, a decision matrix is then constructed from the e...

Precise manipulation of payloads is difficult with cranes. Oscillation can be induced into the lightly damped system by motion of the bridge or trolley, or from environmental disturbances. To address both sources of oscillation, a combined feedback and input shaping controller is developed. The controller is comprised of three distinct modules. A feedback module detects and compensates for posi...

The construction industry is suffering from aging workers and frequent accidents, as well low productivity. Automation robotics regarded a promising approach for enhancing the development of industry, automatic operation cranes, an important aspect construction, attracting increasing attention. However, due to complexity dynamics sites, it difficult cranes automatically recognize locate lifting...

CONDENSED statements of Association finances for the year 1952, prepared by the auditing firm of G. P. Graham & Company, are published herewith, in order that the entire membership may be fully informed regarding the financial operations, obligations, and resources of the AAAS. The first two statements summarize operating receipts and expenditures. Once again the annuity payments to the Cattell...

We expose a theorem of Pila and Wilkie on counting rational points in sets definable in o-minimal structures and some applications of this theorem to problems in diophantine geometry due to Masser, Peterzil, Pila, Starchenko, and Zannier.

William L. Wilkie is Nathe Professor of Marketing, University of Notre Dame (e-mail: [email protected]). How Did This Issue Come About? For much of my career, I have been intrigued with trying to comprehend what the field of marketing is actually about (and what it might be about, what it could be about, what it should be about, and so forth). In recent years, I have joined with my colleague Eliza...

In 1981, Paris and Wilkie [21] indicated it was an open question whether IΣ0 would satisfy the Second Incompleteness Theorem for Herbrand deduction. We will show that IΣ0 will both obey and defy the Herbrandized version of the Second Incompleteness Theorem, depending on which of several equivalent definitions of IΣ0 one examines.

This paper addresses the development of a novel antisway control approach for marine shipboard cranes, offering stability, safety, and efficiency during lifting, handling, transportation, and other manipulation. The proposed idea consists of the development of an integrated system with control strategies to both reduce the effect of three-dimensional payload pendulation and to minimize wave imp...

This paper deals with the problem of constructing the schedule for the operations of a group of quay cranes devoted to discharge/load a set of groups of containers from a vessel at a maritime container terminal. The schedule is constructed starting from the assignment of each individual group of containers to a quay crane under the goal of minimizing the overall vessel completion time, aka the ...
