Image-Based Analysis of Plate Separation and Clearance Distribution in Wet Clutches
Applied SciencesA fundamental understanding of wet clutches’ drag loss behavior is essential for designing efficient clutch systems. It has been widely recognized that the separation behavior immediately after disengaging the clutch and the resulting clearance ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Dynamic Capacity and Surface Fatigue Life for Spur and Helical Gears [PDF]
A mathematical model for surface fatigue life of gear, pinion, or entire meshing gear train is given. The theory is based on a previous statistical approach for rolling-element bearings. Equations are presented which give the dynamic capacity of the gear

Autism Research, EarlyView.ABSTRACT This study measured experiences of parenting stress and stressful life events in caregivers of families with a toddler who has either an autistic or non‐autistic older sibling(s). Caregivers of toddlers (12–18 months old) with older autistic siblings (Sibs‐autism; n = 58) and toddlers with older non‐autistic siblings (Sibs‐NA; n = 46 ...

A mathematical model of an active control landing gear for load control during impact and roll-out [PDF]
A mathematical model of an active control landing gear (ACOLAG) was developed and programmed for operation on a digital computer. The mathematical model includes theoretical subsonic aerodynamics; first-mode wing bending and torsional characteristics ...

British Educational Research Journal, EarlyView.Abstract The latest reform of initial teacher education (ITE) in France, introduced in 2021, aims to make teacher training less theoretical and therefore more ‘practical’. New elements, such as the replacement of the Écoles Supérieures pour le Professorat et l'Éducation (ÉSPÉs) by the Instituts Nationaux Supérieurs du Professorat et de l'Education ...

New generation methods for spur, helical, and spiral-bevel gears [PDF]
New methods for generating spur, helical, and spiral-bevel gears are proposed. These methods provide the gears with conjugate gear tooth surfaces, localized bearing contact, and reduced sensitivity to gear misalignment.
