This study presents an integrated proof‐of‐concept robotic platform for targeted delivery applications. A hybrid magnetic actuation system achieves single‐input (z) multistate stabilization (x, y, ϕ, and θ) for precise capsule transport with submillimeter positioning accuracy.

Large order Reynolds expansions for the Navier–Stokes equations
We consider the Cauchy problem for the incompressible homogeneous Navier-Stokes (NS) equations on a d-dimensional torus, in the C^infinity formulation described, e.g., in [25]. In [22][25] it was shown how to obtain quantitative estimates on the exact solution of the NS Cauchy problem via the "a posteriori" analysis of an approximate solution; such ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

Derivation of the Reynolds equation for lubrication of a rotating shaft [PDF]
In this paper, using the asymptotic expansion, we prove that the Reynolds lubrication equation is an approximation of the full Navier– Stokes equations in thin gap between two coaxial cylinders in relative motion. Boundary layer correctors are computed. The error estimate in terms of domain thickness for the asymptotic expansion is given. The corrector

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

‘Shelter is a Dignity’: Rental Racism, Stress and Housing (In)justice
ABSTRACT Australia's private rental sector is in crisis, and culturally and racially minoritised renters face compounded harms through both covert and everyday direct forms of rental racism. Drawing on five community‐based focus groups in Melbourne (n = 37), the paper explores how racism manifests across the rental pathway and how it structures the ...

THE STUDY ON THE PRIMARY SEALING WITH COAXIAL ROUND-SHAPED SURFACES [PDF]
The paperwork studies the way of calculation of the interstitial pressure with Reynolds equation for the particular case of the primary sealing with coaxial round-shaped surfaces, one fixed and the other one rotating around Oz axis.

Mass or heat transfer inside a spherical gas bubble at low to moderate Reynolds number [PDF]
Mass (or heat) transfer inside a spherical gas bubble rising through a stationary liquid is investigated by direct numerical simulation. Simulations were carried out for bubble Reynolds number ranging from 0.1 to 100 and for Péclet numbers ranging from 1

ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.
