The Role of 3D Printing Technologies in Soft Grippers

Advanced Materials, Volume 36, Issue 34, August 22, 2024.
This article examines the applications of 3D printing to soft grippers, including those with sensors and those made of both functional and nonfunctional materials. The various classes of soft grippers that can be manufactured using 3D printing are discussed. There is also a discussion of challenges and potential development paths.

Finite element approximation of the $p(\cdot)$-Laplacian

, 2014
We study a~priori estimates for the Dirichlet problem of the $p(\cdot)$-Laplacian, \[-\mathrm{div}(|\nabla v|^{p(\cdot)-2} \nabla v) = f. \] We show that the gradients of the finite element approximation with zero boundary data converges with rate $O(h ...

Novel technique of vibration minimization during hard machining

Engineering Reports, Volume 6, Issue 8, August 2024.
This research study examines the performance of electrorheological fluids, also referred to as smart fluids, which have gained popularity because they instantly alter when exposed to an external magnetic or electric field. When high voltage is applied, the ER fluid quickly changes from a viscous liquid to a semisolid state, which is reversible.

Ekeland Variational Principle in the Variable Exponent Sequence Spaces ℓ_p(·)

Mathematics, 2020
In this work , we investigate the modular version of the Ekeland variational principle (EVP) in the context of variable exponent sequence spaces ℓ p ( · ) . The core obstacle in the development of a modular version of the EVP is the failure

Investigation about Electrorheological Squeeze Film Damper Applied to Active Control of Rotor Dynamic

International Journal of Rotating Machinery, 1997
Electrorheological (ER) fluids, discovered in 1947 by W. WINSLOW, are concentrated suspensions of solid particles in an oily base liquid. Exposed to a strong electric field, their resistance to flow increases very greatly and this change is progressive ...

Reversed Currents in Charged Liquid Bridges

, 2017
The velocity profile in a water bridge is reanalyzed. Assuming hypothetically that the bulk charge has a radial distribution, a surface potential is formed that is analogous to the Zeta potential.

Electric field induced gelation in aqueous nanoclay suspensions

, 2018
Aqueous colloidal Laponite clay suspensions transform spontaneously to a soft solid-like arrested state as its aging or waiting time increases. This article reports the rapid transformation of aqueous Laponite suspensions into soft solids due to the ...

Existence for the steady problem of a mixture of two power-law fluids [PDF]

, 2012
The steady problem resulting from a mixture of two distinct fluids of power-law type is analyzed in this work. Mathematically, the problem results from the superposition of two power laws, one for a constant power-law index with other for a variable one.
