The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

open access: yesStructural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Swing-out rail system separates overhead crane rails [PDF]

open access: yes, 1966
Swing-out rail system separates and reconnects the overhead traveling crane rails of a building to provide for the passage of a thick concrete radiation shield sliding door through the rails. In the swing-out position, the rail cantilevered from an axial

Advancing Model‐Based Systems Engineering in the Development of Naval Vessel Systems Architecture

open access: yesSystems Engineering, EarlyView.
ABSTRACT The increasing complexity of modern naval vessels due to technological advancements poses challenges for early‐stage ship design (ESSD). Developing well‐defined system architectures and adopting systems engineering approaches are essential to address these challenges.

Dynamic Responses of an Overhead Crane’s Beam Subjected to a Moving Trolley with a Pendulum Payload

open access: yesShock and Vibration, 2019
An overhead crane with a flexible cable is an underactuated system; the vibration of the crane’s beam and the residual swinging of the payloads cause fatigue in the crane and affect the precise positioning of the payloads.

Optimal motion planning for overhead cranes [PDF]

open access: yesIET Control Theory & Applications, 2014
Overhead cranes are widely used in industrial applications for material displacing. Many linear or non‐linear control schemes have been proposed for overhead cranes and implemented on electronic systems, but energy efficiency of transportation has seldom been considered in motion planning.

Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

open access: yesWildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the
