Angular kinematics during top speed sprinting in male intercollegiate track and field and team sport athletes

open access: yesFrontiers in Sports and Active Living
In this investigation we examined lower extremity angular kinematics and top speed sprinting performance in 98 male intercollegiate athletes with backgrounds in either track and field (TF, n = 28) or team sports (TS, n = 70).

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

БЕЗДАВАЧЕВЕ КЕРУВАННЯ КУТОВОЮ ШВИДКІСТЮ ДВИГУНІВ ПОСТІЙНОГО СТРУМУ НА ОСНОВІ НАТУРАЛЬНИХ ВЛАСТИВОСТЕЙ СТІЙКОСТІ

open access: yesПраці Інституту електродинаміки Національної академії наук України
In this paper, a speed control system for permanent magnet DC motor is designed which does not require an angular speed sensor. It guarantees asymptotic tracking of the reference angular speed trajectories under the action of a constant unknown load ...
