Exact Methods for the Cumulative Capacitated Vehicle Routing Problem With Time Windows

open access: yesNetworks, EarlyView.
ABSTRACT This article studies the cumulative capacitated vehicle routing problem with time windows (CCVRPTW). The CCVRPTW consists of deciding the routing schedules for a set of homogeneous capacitated vehicles such that the latency, that is, the sum of the service start times at the customers, is minimized and the time windows as well as the vehicle ...

Comparison of Calculation Models for Bucket Foundation in Sand

open access: yes, 2012
The possibility of fast and rather precise preliminary offshore foundation design is desirable. The ultimate limit state of bucket foundation is investigated using three different geotechnical calculation tools: [Ibsen 2001] an analytical method, LimitState:GEO and Plaxis 3D.

The place bonding potential of nature‐based citizen science with refugee children and youth

open access: yesPeople and Nature, EarlyView.
Abstract Nature‐based citizen science often involves close interaction with places. In addition to providing benefits, such as learning opportunities and contact with nature, it can facilitate and shape bonds between people and places. Research exploring the place bonding potential of such projects is still in its infancy. This paper addresses this gap

Disposition Model for Permafrost Degradation in Mountainous Regions

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Genomic architecture and breeding trade‐offs of coconut drought tolerance

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The coconut palm is an extremely popular and economically important crop, with around 65 million tonnes produced in 2023. Although Africa's coconut sector is growing rapidly, it—and the livelihoods that depend on it—is threatened by climate change, particularly increased drought.

Design of a Novel Gripping Mechanism and Dual Manipulator Robotic System for Apple Harvesting Using Tractor

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The architecture of apple orchards can be converted to easier operation by implementing the use of a low‐cost, tractor‐mounted, dual manipulator based on a robotic harvesting system with lower degrees of freedom (DoF). To accurately avoid injuries by detecting apples, an efferent, real‐time vision system that includes a new gripping mechanism ...

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

Too Hot, Too Cold, Just Right: Thermal Modulating Capacity of Different Sources of Groundwater Discharge to Salmon‐Bearing Streams

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Groundwater discharge plays a key role in maintaining habitat suitability for cold‐water fish by generating streamflow and modulating temperatures. However, the thermal influence depends on groundwater source depth and how far groundwater travels from the point of discharge to a receiving stream.
