Privacy Preservation Authentication: Group Secret Handshake with Multiple Groups

open access: yesMathematics, 2023
The technique of group secret handshake (GSH) has been used to help the members affiliated with the same group in achieving private authentication. After executing GSH protocols, the participants affiliated with the group can compute a shared secret key,

An Artificial Vibrissa-Like Sensor for Detection of Flows

open access: yesSensors, 2019
In nature, there are several examples of sophisticated sensory systems to sense flows, e.g., the vibrissae of mammals. Seals can detect the flow of their prey, and rats are able to perceive the flow of surrounding air.

Minsight: A Fingertip‐Sized Vision‐Based Tactile Sensor for Robotic Manipulation

open access: yesAdvanced Intelligent Systems, 2023
Intelligent interaction with the physical world requires perceptual abilities beyond vision and hearing; vibrant tactile sensing is essential for autonomous robots to dexterously manipulate unfamiliar objects or safely contact humans.

Droplet Motion Driven by Liquid Dielectrophoresis in the Low-Frequency Range

open access: yesMicromachines
Electrohydrodynamic wetting manipulation plays a major role in modern microfluidic technologies such as lab-on-a-chip applications and digital microfluidics. Liquid dielectrophoresis (LDEP) is a common driving mechanism, which induces hydrodynamic motion

Rings and covered groups

open access: yesJournal of Algebra, 2008
Let \(G\) be an additive group (not necessarily Abelian) with identity \(0\). The set \(M_0(G)\) of all \(0\)-preserving functions from \(G\) to itself forms a near-ring under pointwise addition and composition of functions. If \(R\subseteq M_0(G)\) is a ring under these operations, then \(R\) is said to be a `subring' of \(M_0(G)\).

Finite Dimensional Group Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
A ring is right finite dimensional if it contains no infinite direct sum of right ideals. We prove that if a group G is finite, free abelian, or finitely generated abelian, then a ring R is right finite dimensional if and only if the group ring RG is right finite dimensional.

Randomized Modality Mixing with Patchwise RBF Networks for Robust Multimodal Pain Recognition

open access: yesComputers
Pain recognition based on multimodal physiological signals remains a challenge, not only because of the limited training data, but also due to the varying responses of individuals.

Idempotents in Group Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
In this note we offer an elementary entirely self-contained proof of a theorem of Kaplansky on idempotents in complex group rings.

Deep learning-driven active sheet positioning using linear actuators in laser beam butt welding of thin steel sheets

open access: yesJournal of Advanced Joining Processes
Welding thin steel sheets in industrial applications is difficult because joint gaps occur during the process, which can lead to weld interruptions. Such welds are considered a reject and in order to avoid the weld to interrupt it is crucial to hinder ...
