Accelerating Musculoskeletal Robotics Through Parametric Design and 3D‐Printed Flexible Structures
Advanced Intelligent Systems, EarlyView.Parametric design and flexible 3D printing create muscle‐, tendon‐, ligament‐, and cushion‐like robotic elements from a single thermoplastic polyurethane material. Tuning lattice patterns adjusts regional mechanical properties and enables coordinated multijoint motions in a life‐sized musculoskeletal leg under external suspension, with partial body ...

Precession-Nutations and Tidal Potential [PDF]
International Astronomical Union Colloquium, 1971 We have previously established (Melchior and Georis, 1968) the equations connecting the development of precession-nutation with the tesseral part of the tidal potential. These equations are:whereωiAirespectively represent the frequencies and amplitudes of the tidal waves, ω the Earth’s rotation velocity,

On the diurnal nutation determination [PDF]
, 1889 The author explains his constant determination of the diurnal nutation which consists in the observation of pole’s nearby stars at six hours apart with use of a powerful meridian circle.L’auteur explique sa détermination des constantes de la nutation ...

An Integrated Fabric‐Pneumatic Soft Sensing System for Multi‐Site Muscle Activity Decoding
Advanced Intelligent Systems, EarlyView.Fabric‐pneumatic chambers convert muscle deformation into pressure signals without electronics at the body‐contact sensing interface. A unified processing pipeline enables static posture classification, continuous elbow‐angle estimation, forearm gesture recognition, and knee‐movement detection across three anatomical sites.

About the initial nutation [PDF]
, 1892 After determining the in initial nutation constants as well as its period, the author decides to check again the importance of this fact, which proves that we can’t study the Earth motion as if it was a solid spheroid.Après avoir déterminé les ...

Climate change and perennial crop production: Evidence of yield impact and adaptation in California
American Journal of Agricultural Economics, EarlyView.Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Nutation damping of dynamically tuned gyroscopes
MATEC Web of Conferences, 2017 The paper deals with the problem of nutation damping of dynamically tuned gyroscopes (DTG). Unlike the common two-axis gyroscopes, the DTG damping torques caused by dry and viscous frictions are absent in gimbal bearings, while those due to the rotor ...

Farm labor scarcity and its uneven impacts on crop producers in the United States
American Journal of Agricultural Economics, EarlyView.Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.
