BACKGROUND Care-needing older adults and disabled individuals often require handrails for assistance of movements, such as sit-to-stand movements. Handrails must be set at the appropriate position; however, the effects of handrail height on joint movement and center-of-gravity movements during sit-to-stand movement remain unclear. In the present study, we sought to clarify the effects of handra...

During a paleomagnetic reversal, Earth's geomagnetic field is about 10% of today's magnitude and its topology far more complex than dipolar. Revealing the solar wind energy transmission during reversal importance for understanding historic space environment. Using global magnetohydrodynamic model implemented with data-reconstructed time-dependent field, this study simulates wind-magnetosphere i...

The stability and repeatability of laser metal deposition is particularly important when processing multiple layers or depositing material on complex component surfaces, requires the use process parameter control including stand-off distance between head substrate. system proposed in this paper for correcting based a chromatic confocal sensor integrated into head. Then, spectral signal acquired...

High-temperature effects have a significant impact on the characteristics of aircraft moving at super- and hypersonic speeds. Due to complexity setting up physical experiment, methods mathematical modelling play an important role in finding aircraft. Numerical air flow around sphere is carried out taking into account high-temperature non-equilibrium chemical reactions. The model includes equati...

Abrasive water jet machining (AWJM) is one of the non conventional machining process for difficult to cut brittle, hard and thin materials. The process parameters which are mainly influence the quality of machining in AWJM are water pressure, stand-off distance, nozzle diameter, traverse speed, abrasive flow rate and abrasive size. This is an environment friendly and relatively inexpensive proc...

We demonstrate subcentimeter depth profiling at a stand off distance of 330 m using a time-of-flight approach based on time-correlated single-photon counting. For the first time to our knowledge, the photon-counting time-of-flight technique was demonstrated at a wavelength of 1550 nm using a superconducting nanowire single-photon detector. The performance achieved suggests that a system using s...

The histologic effects of a contact ultrasound applicator were compared with those of the immersion applicator that is currently used clinically for the treatment of glaucoma. The applicator coupling cone uses a distensible rubber membrane that can be inflated to control stand-off distance relative to the surface of the eye. This feature allows the focal point of the therapeutic beam to be plac...

A remote-sensing system that can determine the position of hidden objects has applications in many critical real-life scenarios, such as search and rescue missions and safe autonomous driving. Previous work has shown the ability to range and image objects hidden from the direct line of sight, employing advanced optical imaging technologies aimed at small objects at short range. In this work we ...

Numerical simulations of magnetohydrodynamic (MHD) hypersonic flow over a cylinder are presented for axial- and transverse-oriented dipoles with different strengths. ANSYS CFX is used to carry out calculations for steady, laminar flows at a Mach number of 6.1, with a model for electrical conductivity as a function of temperature and pressure. The low magnetic Reynolds number (<<1) calculated ba...
