Probing Viscoelasticity of Polymeric Coatings Using Nonlinear Dynamic Atomic Force Microscopy

Small Methods, EarlyView.
For soft materials it is essential to characterize both the elastic and viscous material properties. Using an atomic force microscope, the hardening nonlinearity induced by a tip‐sample contact and bifurcation points can be used to separately estimate the visco‐ and elastic parts of the tip‐sample interaction force.

Enhancing SHM with the extension of the deformation area difference method into the strain area difference method

Structural Concrete, EarlyView.
Abstract This study contributes to the fields of nondestructive testing (NDT) and structural health monitoring (SHM), which are pivotal for extending the service life of infrastructure and aligning with sustainability goals in construction. The study emphasizes an advanced application of the deformation area difference (DAD) Method, focusing on the ...

Thermal prestressing of subsequently slotted reinforcement—Experimental and numerical development and optimization of an induction method

Structural Concrete, EarlyView.
Abstract Many infrastructure buildings show deficits in their load‐bearing capacity and need to be strengthened in the short or medium term. However, the available methods are usually not effective for the self‐weight without temporary raising or prestressing the structure.

Experimental study on the impact of traffic‐induced vibrations on early‐age concrete

Structural Concrete, EarlyView.
Abstract The COUNT (Concreting under Traffic) research project systematically examined the effects of traffic‐induced vibrations on early‐age, hardening concrete—a critical issue for bridge construction and renovation. Traffic closures are often imposed during such projects to mitigate potential damage from vibrations.

A Method of Exciting Vibrations in Plates, Membranes, etc., Based on the Bernoulli Principle [PDF]

Proceedings of the Physical Society of London, 1921
It is known that a plate placed close to a flanged orifice from which a stream of air or liquid is issuing is attracted towards the orifice. If the plate be mounted as a diaphragm it can be excited to strong vibration by a suitable blast, and a loud sound is produced with high efficiency.

Management of Vocal Fold Leukoplakia

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Vocal fold leukoplakia (VFL) is a descriptive term for a white plaque in the true vocal folds (TVF). It is estimated at 10.2 cases per 100,000 males and 2.1 per 100,000 females. The most critical aspect of managing a VLF is achieving an accurate pathological diagnosis, since a white plaque in the TVF can have numerous differential diagnoses ...

Graph neural network‐based attack prediction for communication‐based train control systems

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The Advanced Persistent Threats (APTs) have emerged as one of the key security challenges to industrial control systems. APTs are complex multi‐step attacks, and they are naturally diverse and complex. Therefore, it is important to comprehend the behaviour of APT attackers and anticipate the upcoming attack actions.

The Relations of Order and the Identity of the Indiscernible: Leibniz´s Solution to the Problem of the Indistinction between Repose and Uniform Movement [PDF]

The indistinction between repose and uniform movement exposed in the principle of inertia marks one of the most famous dissertations: the discussion between Newton and Leibniz. Through their respective conceptions of space, both seek to solve the problem
