Overhead cranes are broadly used in industry. However, undesirable load swing is often induced with transportation. Therefore, various researches about control of positioning and swing suppression of crane load have been made. On the other hand, a worker operates a crane skillfully by manual-operation in transportation. Hence, support system and automation of crane operation are expected from t...

At the research center IFOR (Intelligenta Fordon Off-Road), one long-term goal is the development of fully autonomous forest machines. Some of the driving objectives are to increase productivity and to improve the working environment for the operator. The development of teleoperated vehicles is one step in this direction, it is however still facing a number of challenges. This thesis examines h...

A letter e ∈ Σ is said to be neutral for a language L if it can be inserted and deleted at will in a word without affecting membership in L. The Crane-Beach Conjecture, which was recently disproved, stated that any language containing a neutral letter and definable in FO is in fact FO[<] definable and is thus a regular, star-free language. More generally, we say that a logic or a computational ...

The midcontinental population of sandhill crane (Grus canadensis) includes about 500,000 birds and provides valuable recreational crane-watching and hunting opportunities in Canada and the United States. It comprises three subspecies, one of which (G. c. rowani) was of uncertain taxonomic status and another of which (G. c. tabida) merited protection from excessive harvest due to its small popul...

This paper introduces a modular prototyping system architecture that allows for the modeling, simulation and control of different maritime cranes or robotic arms with different kinematic structures and degrees of freedom using the Bond Graph Method. The resulting models are simulated in a virtual environment and controlled using the same input haptic device, which also provides the user with a ...

We consider a container operator, who serves a number of shipping lines by discharging and loading their periodically arriving container vessels. Disruptions on vessels’ travel times lead to stochastic arrivals in the port. To cope with these disturbances, the operator and each vessel line agree on two types of arrivals: arrivals i) within, and ii) out of a so-called arrival window. If a vessel...

Problem statement: Most of the common gantry crane results in a sway motion when transporting the load as fast as possible. In addition, precise cart position control of gantry crane must required a zero or near zero residual sway. Approach: In this study, the development of hybrid control schemes for input tracking and anti-sway control of a gantry crane system was investigated. To study the e...

Techniques for measuring upper femoral torsion in children have been progressively developed by Dunn (1952), Ryder and Crane (1953), Dunlap, Shands, Hollister, Gaul and Streit (1953), Magilligan (1956) and Shands and Steele (1958). The projected neck-shaft angle of inclination and the projected angle of femoral torsion (Fig. 1) may be used to plot the true torsion on a table based on a mathemat...

8 The annual Sandhill crane (Grus canadensis) migration through Nebraska, which is 9 thought to be a major source of fecal pollution to the central Platte River, is of unknown 10 human health risk. To better understand potential risks, the presence of Campylobacter 11 species and three fecal indicator bacterial groups (Enterococcus spp., Escherichia coli 12 and Bacteroidetes) were assayed by PC...

This paper presents a practical method of adding problem-specific notation to an established computer language. Our idea is to use unrestricted operator overloading as a tool to map the problem domain notation directly into an existing programming language. Our method introduces new operator symbols and function names into a host language by overloading existing usage. We extend the host progra...
