A C++ programmer said to Rabbi Shammai: " I promise to try object technology if you can explain the secret of objects while standing on one foot. " Rabbi Shammai whacked him on the head with a 10-by-2 ruler. He went to Rabbi Hillel who, standing on one foot, answered: " No overloading. That is the secret of objects. All the rest is commentary. " Some commentary now. The beauty of object technol...

The paper talk over the proposal of use a combined vision system architecture for solved well known issue occurring in material handling devices (MHDs) exploitation, especially in the crane devices. The described in the presented paper stereovision system for work space mapping and non-contact sensor type for rope angle swinging measure were a part of solutions enabling a full autonomous naviga...

Tingginya waktu downtime mesin crane di salah satu perusahaan manufaktur produsen baja billet menyebabkan terganggunya kelancaran proses produksi. Untuk mengatasi hal ini serta untuk mencapai kestabilan performa crane, maka perlu adanya tindakan perawatan yang intensif pada setiap komponen crane. Metode Reliability Centered Maintenance (RCM), digunakan mengetahui interval dan dampak positif dil...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

Invasive plants continue to spread in riparian ecosystems, causing both ecological and economic damage. This research investigated the impacts of common reed, purple loosestrife, riparian shrubland, and riparian woodlands on the quality and quantity of sandhill crane roosting habitat in the central Platte River, Nebraska, using a discrete choice model. A more detailed investigation of the impac...

Requirements of modern cranes and another heavy-duty material handling systems result in demand for sophisticated crane control and automation systems capable of handling loads fast and reliable connection to the particular information systems. These systems continuously provide up-dated information about containers moves and crane status. The total function is built up of a number of distinct ...

The behavior of many mechanical systems, such as overhead cranes, can be predicted through intuitive observation of their motion under various forces. Mathematical modeling of an overhead crane shows that it is highly coupled. Nonetheless, it is surprisingly easy for an experienced crane operator to drive payloads to target positions with minimal cable swing. This observation naturally promotes...
