Business Strategy and the Environment, EarlyView.ABSTRACT Global imperatives, such as climate change, environmental concerns, and carbon emissions, make green transformation an inevitability in the logistics sector. Green logistics strategy formulation is an economic choice problem, but it also turns out to be a multicriteria decision‐making (MCDM) process that encompasses the triple bottom line (TBL)

Digital documentation of railway tunnel inspection in Austria
Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Rolling contact fatigue (RCF) defects of rails in Japanese railways and its mitigation strategies
Electronic Journal of Structural Engineering, 2013 Rail is the one of the most important materials to support and guide railway vehicles safely and smoothly. Since rail sufferes from various interacting forces and environmental atmosphere, wear and fatigue pose large problems with wheel and rail. Hence,
