Shipbuilding crane manipulator with closed-chain structure: structural design and kinematic performance analysis

Mechanics & Industry
Traditional shipbuilding crane manipulator is widely used in the process of block lifting and erection of ships, but there are generally problems, such as inflexible output trajectory, limited workspace and low working efficiency. In order to solve above

Consideration of dynamic loads in the design of metal structures of gantry cranes [PDF]

Научно-технический вестник Брянского государственного университета
The design calculation of crane metal structures is usually performed according to load combinations, for which the dynamic coefficients are strictly defined in the regulatory documentation.

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...

Use of balancing rope for damping of cargo sways moved by a loading crane [PDF]

Научно-технический вестник Брянского государственного университета, 2019
It has been proposed to add a load-lifting crane with a flexible cable suspension of cargo with an additional side balancing cable. The latter is located predominantly horizontally.

Straddle carrier routing optimization at container terminals utilizing telemetry‐based prediction

International Transactions in Operational Research, EarlyView.
Abstract Efficient vehicle routing and scheduling for horizontal transport means on container terminals can reduce lead times and travel distances, resulting in fuel savings and productivity gains. We apply machine learning to emulate operational processes, bridging the gap between theoretical optimization models and real‐world practices at container ...

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, EarlyView.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Carbon Populism and Representative Politics: On Why Fossil Fuel Firms Speaking for ‘The People’ Is a Bad Idea

Journal of Management Studies, EarlyView.
Abstract Despite growing recognition that countries around the world must transition to a low‐carbon economy, global greenhouse gas emissions continue to rise. One way that decarbonization has been obstructed, we argue, is by fossil fuel firms intentionally conflating their agenda with ‘the people’, evoking notions of national identity, security and ...

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...

Analysis of the influence on the hydraulic lifting circuit of the boom crane when the characteristics of the steel wire rope changes

, 2021
In the process of lifting and landing of large hydraulic crane fully loaded, the working condition conversion makes the stress of steel wire rope change frequently and generate additional dynamic load, which makes the movement of the crane unstable and ...

Muscle performance but not biomechanics associate with second knee injury in a matched cohort of athletes who passed functional return‐to‐sport criteria after ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 3, Page 1118-1130, March 2026.
Abstract Purpose Athletes remain at risk for a second knee injury after anterior cruciate ligament reconstruction (ACLR), even after passing return‐to‐sport (RTS) testing. While biomechanical asymmetries have been linked to reinjury, it is unclear whether deficits persist in athletes who meet RTS criteria.
