Hoisting frame facilitates handling of large objects [PDF]

open access: yes, 1968
Hoisting frame can be used with a standard 5-ton forklift to handle the large spreader bars, or other bulky pieces of equipment, much faster and more efficiently than with a boom or gantry crane.

Multi‐neighborhood simulated annealing for the home healthcare routing and scheduling problem

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 1, Page 38-67, January 2026.
Abstract Over time, the focus on supportive and geriatric care has shifted from being predominantly provided in institutional settings like nursing or rest homes to be delivered within the homes of the patients. Trained caregivers now provide home healthcare services by visiting patients in their own homes and carrying out specific services based on ...

Development of a Model Order Reduced Arbitrary Lagrangian Eulerian (MORALE) Formulation for Structures Subjected to Dynamic Moving Loads

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT Fast and efficient simulation strategies are a basic requirement of technologies such as digital twins. Particularly for roadway infrastructure, recent developments have demonstrated that the arbitrary Lagrangian Eulerian (ALE) formulation can be utilized to improve computational efficiency, when simulating the response of such pavement ...

Integration of IoT and machine learning for enhancing physiological workload management of tunnel construction workers

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 25, Page 4378-4396, 20 October 2025.
Abstract Occupational accidents caused by heavy physical labor remain common among construction workers. Although recent studies have attempted to combine wearable devices with artificial intelligence technology for workload monitoring, several limitations remain: Devices are difficult to deploy on‐site, laboratory‐based studies lack on‐site ...
