Determination of alfalfa leaf area by non-destructive method [PDF]

Communications in Plant Sciences, 2011
The knowledge of plant leaf area is important to evaluate the vegetal growth. The objective of this research was to determine a mathematical equation to estimate successfully alfalfa (Medicago sativa) leaf area by measuring linear dimensions of the leaf ...

Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Linear measurements of the leaf blade in xaraes and massai grasses for estimation of the leaf area [PDF]

Biotemas, 2013
Knowledge on the leaf area of foraging grasses is essential, since it’s one of the most important variables in the evaluation of plant growth. Thus, one aimed at determining equations which allow, through simple measurements of leaf length, as well as ...

Data‐Driven Bulldozer Blade Control for Autonomous Terrain Leveling

Advanced Robotics Research, EarlyView.
A simulation‐driven framework for autonomous bulldozer leveling is presented, combining high‐fidelity terramechanics simulation with a neural‐network‐based reduced‐order model. Gradient‐based optimization enables efficient, low‐level blade control that balances leveling quality and operation time.

Origami‐Inspired Morphing Fuselage for Agile Fixed‐Wing Flight

Advanced Robotics Research, EarlyView.
Conventional aircraft steer with rigid control surfaces. SoAR instead replaces the fuselage itself with a cable‐driven origami continuum body that bends in 3D and compresses on demand. Whole‐fuselage morphing steers fixed‐wing flight: achieving sharp, near‐zero‐radius turns and rapid braking without ailerons, rudder, or elevator, while the same ...

Altitude-dependent Variations in Some Morphological and Anatomical Features of Anatolian Chestnut

BioResources
Morphological measurements of Anatolian chestnut (Castanea sativa Mill.) leaves were done within the borders of Abana district of Kastamonu province. The study was conducted using mixed (oak, beech, hornbeam, black pine, and yellow pine) medium (41% to ...

XeraBorg: Neural Control of Tail‐Flick Escape for Backward Propulsion in Cyborg Crayfish

Advanced Robotics Research, EarlyView.
This work presents the first controlled tail‐flick propulsion method for the cyborg Cherax quadricarinatus. Comprehensive experiments establish a foundational framework for using the crayfish's natural escape mechanism as a locomotion strategy, expanding its potential as an underwater and amphibious mobile robot.

Thermodynamics of Concomitant Charge‐Transfer, Antiferromagnetic, and Isostructural Phase Transitions in Barocaloric ACu3Fe4O12 Quadruple Perovskites

Advanced Science, EarlyView.
A copper‐iron charge transfer instability drives concomitant electronic, magnetic, and isostructural phase transitions in ACu3Fe4O12${\rm ACu}_3{\rm Fe}_4{\rm O}_{12}$, with an inverse barocaloric effect. A minimal Landau theory ties these thermodynamic signatures together, revealing a pressure‐independent transition entropy with comparable charge and ...

Investigation of the Static and Dynamic Performance of Leaf Springs under Different Shapes, Leaf Numbers, and Beam Widths

Journal of Engineering
This study is related to a new geometrical design of automotive leaf springs that involves substituting the common trapezoidal base and circular shape with a circular base plate and parabolic shape. The main aim is to explore how the shape of the base and the profile of curvature affect the performance of the leaf springs, both at rest and in dynamic ...
