The Force Between Two Sliding Bodies When Observed from a Third Moving Body
Tribology Online, 2011 This paper pertains to the observations of the sliding friction force from different moving bodies. The paper derives the equations required to predict the forces on the free-body diagrams of two sliding bodies when observed from a third moving body. The

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective The Gold Coast criteria permit diagnosis of amyotrophic lateral sclerosis (ALS) even without upper motor neuron (UMN) signs. However, whether ALS patients with UMN signs (ALSwUMN) and those without (ALSwoUMN) share similar characteristics and prognoses remains unclear.

Grousers Effect in Tracked Vehicle Multibody Dynamics with Deformable Terrain Contact Model
Applied Sciences, 2020 In this work, a multibody model of a small size farming tracked vehicle is shown. Detailed models of each track were coupled with the rigid body model of the vehicle. To describe the interaction between the track and the ground in case of deformable soil,

Traumatic Microhemorrhages Are Not Synonymous With Axonal Injury
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Diffuse axonal injury (DAI) is caused by acceleration‐deceleration forces during trauma that shear white matter tracts. Susceptibility‐weighted MRI (SWI) identifies microbleeds that are considered the radiologic hallmark of DAI and are used in clinical prognostication.

Effect of Bed Forms on the Detachment of Benthic Algae by the Sediment Transportation
Journal of Water and Environment TechnologyA series of hydraulic experiments were conducted for quantitative evaluation on the detachment effect of benthic algae on uneven riverbeds caused by sediment loading. We focused on the shielding part created by the exposure height of gravel and the width

Driving Cycle Adaption and Design Based on Mean Tractive Force [PDF]
IFAC Proceedings Volumes, 2013 Abstract Driving cycles are used for certification, for comparison of vehicles, and to an increasing extent as an engineering tool in vehicle design. A situation with only a few fixed driving cycles to use would then lead to the risk that a test or design would be tailored to details in the driving cycle instead of being representative.
