An experimental study of low velocity impact (LVI) on fibre glass reinforced polymer (FGRP) [PDF]

open access: yes, 2014
This paper investigates the low velocity impact load and absorbed energy corresponding to the incident impact level of Type C-glass/Epoxy 600 g/m² and Type E-glass/Epoxy 800 g/m² composites.

Structure–Function Decoupling of the Sensorimotor and Default Mode Networks in Black Americans With MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Trajectory-capture cell instrumentation for measurement of dust particle mass, velocity and trajectory, and particle capture [PDF]

open access: yes
The development of the polyvinylidene fluoride (PVDF) dust detector for space missions--such as the Halley Comet Missions where the impact velocity was very high as well as for missions where the impact velocity is low was extended to include: (1) the ...

Investigation of experimental research on the low velocity impact damage behavior of ncf composite plates – COMPLAS XII [PDF]

open access: yes, 2013
In this study an experimental investigation is performed on the impact response of non-crimp fabric composite plates at room temperature. Chopped strand mat combi is used as reinforcing material and two kinds of matrix; epoxy and polyester, are also used

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles
