The quality of preparations carried out before building work commences has a significant impact on the smooth running and overall financial costs construction project. use machinery, which is crucial with regard to efficiency process, plays an important role. In construction, machines in question are mainly tower cranes. paper presents new method for assessing utilisation cranes over time durin...

The objective of this paper is to analyze the crane structures as a step to study their effects on the structures working integrally with them. The interaction between cranes and those structures has dominant effects on the global system behavior. Crane structures may have many forms of space structures. It is not logical or economical to perform experimental modal analysis to all of them to in...

Oyster culture is an aquaculture activity that mostly carried out in Japanese waters. While Indonesia, oyster shells are widely consumed, but they have not been produced through the process caught on high seas. This study aims to determine how application of technology and transportation sale Japan. Based literature studies activities at Kamashima-Japan company, important part farming activitie...

—Little information exists on breeding Greater Sandhill Cranes (Grus canadensis tabida) in riparian wetlands of the Intermountain West. We examined the nesting ecology of Sandhill Cranes associated with riparian and palustrine wetlands in the Henry’s Fork Watershed in eastern Idaho in 2003. We located 36 active crane nests, 19 in riparian wetlands and 17 in palustrine wetlands. Nesting sites we...

In recent years, high speed and automation have been promoted to provide higher efficiency for container handling in cranes handling containers such as container cranes and transfer cranes. To bring about automation in these cases, it is important to detect the positioning of hoisting loads accurately. In 1996, Mitsubishi Heavy Industries, Ltd.(MHI) developed a hoisting load position sensor usi...

As important equipment in offshore engineering and freight transportation, shipboard cranes, working non-inertial coordination systems, are complicated nonlinear systems with strong couplings typical underactuation. To tackle the challenges controller design for boom which is a representative type of comprehensive framework embedding moving horizon estimation (MHE) model predictive control (MPC...

Due to loss and degradation of natural wetlands, waterbirds increasingly rely on surrounding human-dominated habitats to obtain food. Quantifying vigilance patterns, investigating the trade-off among various activities, and examining the underlying mechanisms will help us understand how waterbirds adapt to human-caused disturbances. During two successive winters (November-February of 2012-13 an...
