Development of a Step Counting Algorithm Using the Ambulatory Tibia Load Analysis System for Tibia Fracture Patients [PDF]

open access: yes, 2018
Introduction: Ambulation can be used to monitor the healing of lower extremity fractures. However, the ambulatory behavior of tibia fracture patients remains unknown due to an inability to continuously quantify ambulation outside of the clinic.

Experimental study on equilibrium initiation and extension of multiple clusters of fractures based on true triaxial physical simulation

open access: yesJournal of Natural Gas Geoscience, 2023
In the context of tight sandstone reservoirs in the Ordos Basin characterized by compact and heterogeneous rock formations, conventional fracturing techniques yield monolithic fracture shapes, rendering 3D reservoir reconstruction unattainable.

Analysis of the asynchronous electrical drives for the industrial machines with a cyclic (intermittent) electrical shock load

open access: yesBakar, 2023
The analysis and proposed optimization technique of asynchronous electric drives of production machines with a cyclic impact load, under the condition of minimum energy consumption, was presented in this paper. The mean values of the electric motor torque in the working range of a slider, were adopted in calculation. The derived formulae can be used to

Physiology and prevention of heel ulcers: The state of science [PDF]

open access: yes, 2003
The prevalence of heel ulcers across settings is high and is increasing. Prevention of ulcers requires knowledge of their etiology and the scientific basis for preventive care. The interaction between external pressure and the heel vasculature is central
