Making lemonade out of lemons: port operators’ perceptions of their port security regulation compliance

open access: yesWMU Journal of Maritime Affairs (JoMA), 2015
Firms often complain about the implementation of new regulations. Many regulations are perceived as an additional cost for no business value. This paper reviews the perceptions by the US and EU port and terminal managers of the business value port ...

Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

open access: yesAdvanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping

open access: yesAdvanced Materials, EarlyView.
Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...

Automated Evaluation Method for Risk Behaviors of Quay Crane Operators at Ports Using Virtual Reality

open access: yesAlgorithms
Currently, the operational risk assessment of quay crane operators at ports relies on manual evaluations based on experience, but this method lacks objectivity and fairness. As port throughput continues to grow, the port accident rate has also increased,

Threats and New Protection Measures in Inland Navigation

open access: yesPromet (Zagreb), 2010
The density of navigation in the world waterways is considerable, especially because it is more profitable, when compared to other forms of transport. In this paper the authors propose new measures for security protection of inland waterways and of ships

Operation Limits of Integrated Photo‐Rechargeable Batteries

open access: yesAdvanced Materials, EarlyView.
This study elucidates the operational limitations of integrated photo‐rechargeable batteries. We demonstrate that the photo‐charging process is fundamentally restricted not only by material‐to‐material energy level alignment but also by transient capacitive charge accumulation within the cathode framework.

Model of decision for the management of technology and risk in a port community [PDF]

open access: yesDecision Science Letters, 2018
Strategic management in a port system is complex since the Port Community has to coordinate actions and generate synergy among all the private actors that integrate the export and import logistics chains, trade associations and trade unions. Based on the
