Multi-sensor Fusion Road Friction Coefficient Estimation During Steering with Lyapunov Method

open access: yesSensors, 2019
The road friction coefficient is a key parameter for autonomous vehicles and vehicle dynamic control. With the development of autonomous vehicles, increasingly, more environmental perception sensors are being installed on vehicles, which means that more ...

Digital Cognitive Phenotyping for Differential Diagnosis and Monitoring in Neurological Conditions

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To assess the utility, accessibility, and equivalence to supervised scales of online cognitive assessment in older individuals with cognitive impairment. Methods Patients with Alzheimer's disease (AD, n = 31), idiopathic normal pressure hydrocephalus (iNPH, n = 26), and traumatic brain injury (TBI, n = 23) completed online cognitive ...

Digital Cognitive Testing in Mitochondrial Disease: Validity and Challenges for Clinical Trial Use

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Primary mitochondrial disease is a group of genetic disorders caused by pathogenic variants in nuclear or mitochondrial DNA, often resulting in progressive neurodegeneration and cognitive decline. Current management is primarily supportive, though recent research offers hope for disease‐modifying treatments in the future.

A double interaction brush model for snow conditions

open access: yes, 2019
Commonly used tire models for vehicle handling simulations are derived on the assumption of a flat and solid surface. Snow surfaces are non-solid and may move under the tire.

A Brush‐Type Tire Model with Nonsmooth Representation [PDF]

open access: yesMathematical Problems in Engineering, 2019
This paper proposes a brush‐type tire model with a new mathematical representation. The presented model can be seen as a generic model that describes the distributed viscoelastic force and Coulomb‐like friction force, which are balancing each other at each point, in the contact patch. The model is described as a partial differential algebraic inclusion

Neurologic Manifestations of Long COVID Affect Adult Females More Severely Than Males

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To characterize differences in neurologic manifestations of postacute sequelae of SARS‐CoV‐2 infection (Neuro‐PASC) between females and males. Methods Cross‐sectional study of the first consecutive 261 posthospitalization Neuro‐PASC (PNP) and 2068 nonhospitalized Neuro‐PASC (NNP) patients evaluated at the Neuro‐COVID clinic between ...

Effect of Friction Model and Tire Maneuvering on Tire-Pavement Contact Stress

open access: yesAdvances in Materials Science and Engineering, 2015
This paper aims to simulate the effects of different friction models on tire braking. A truck radial tire (295/80R22.5) was modeled and the model was validated with tire deflection. An exponential decay friction model that considers the effect of sliding

Tire vibration analysis of radial direction on the restraint effect of contact condition

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Road noise is one of the main sound sources exciting passenger car interior noise. This noise is excited by road roughness. Vibration and noise characteristics in road noise have strong interaction with tire vibration characteristics.
