Single Smooth Waveform Command‐Shaping Control of Overhead Crane Systems Utilizing Two‐Stage Acceleration–Deceleration Profile for Short‐Moving Point‐to‐Point Maneuver

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern industrial demand for efficient material handling in confined spaces has driven the need for overhead cranes capable of short‐distance point‐to‐point maneuvers without compromising payload stability. Conventional three‐stage shaper profiles, experiencing acceleration, cruising, and deceleration, become inefficient or infeasible for ...

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

PLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

A branch-and-price algorithm for a hierarchical crew scheduling problem. [PDF]

We describe a real-life problem arising at a crane rental company. This problem is a generalization of the basic crew scheduling problem given in Mingozzi et al. and Beasley and Cao.

Right tree, right place, right reason: Using knowledge exchange and research co‐design to explore current challenges and opportunities for sustainable urban forest management

PLANTS, PEOPLE, PLANET, EarlyView.
The urban forest provides important environmental and health and well‐being benefits to people living in cities. However, sustainable management of urban trees is challenging as they face interrelated pressures from the urban environment, pests and diseases and climate change.

Anti-Sway Control for Haptic Crane for Application of Material Handling by Using Active Force Control (AFC) [PDF]

, 2010
This paper focuses on anti-sway control system for haptic crane that uses accelerometer and weight sensor as sway sensor and mass calculation of payload. The control method proposed is AFC which is able to control more accurate and robust while transport

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, EarlyView.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Sandhill Crane Roost Selection, Human Disturbance, and Forage Resources [PDF]

, 2016
Sites used for roosting represent a key habitat requirement for many species of birds because availability and quality of roost sites can influence individual fitness. Birds select roost sites based on numerous factors, requirements, and motivations, and

From Green Strategy to Sustainable Development: Corporate Efforts Toward SDG 12 and SDG 13

Sustainable Development, EarlyView.
ABSTRACT Firms are increasingly integrating United Nations Development Goals 12 (Responsible consumption and production) and 13 (Climate action) as a part of their sustainability strategies. However, prior research has rarely examined how these SDGs interact as a unified capability rather than as isolated practices.
