Prevalence and Risk Factors of Work-Related Musculoskeletal Disorders Among Dockworkers: The Role of Psychosocial Stress and Physical Demands in an Iranian Port. [PDF]
Health Sci RepABSTRACT Background and Aim With the development of trade between countries, the transportation of goods has increased, and ports struggle to accommodate the demands of unloading and loading operations. Seaport workers may experience work‐related musculoskeletal disorders (WMSDs), which in many cases result in disabilities.

Discrete-time flatness-based control of a gantry crane [PDF]
Control Engineering Practice, 2022 This article addresses the design of a discrete-time flatness-based tracking control for a gantry crane and demonstrates the practical applicability of the approach by measurement results. The required sampled-data model is derived by an Euler-discretization with a prior state transformation in such a way that the flatness of the continuous-time system
