SMA-Activated Double-Stage Yielding BRB: Experimental and FEM Insights

Buildings
To address the limitations of traditional buckling-restrained braces (BRB), which feature a single-stage yielding and inadequate energy dissipation under small earthquakes, this study proposes a novel double-stage yielding buckling-restrained brace (DSY ...

Probing viscoelastic surfaces with bimodal tapping-mode atomic force microscopy: Underlying physics and observables for a standard linear solid model

Beilstein Journal of Nanotechnology, 2014
This paper presents computational simulations of single-mode and bimodal atomic force microscopy (AFM) with particular focus on the viscoelastic interactions occurring during tip–sample impact.

Galactic Density and Evolution Based on the Virial Theorem, Energy Minimization, and Conservation of Angular Momentum

Galaxies, 2018
Spiral galaxies are spinning, internally densified objects. The Virial Theorem explains galactic rotation curves via its linkage of the rotation rate to the gravitational self-potential (Ug) and the moment of inertia of oblate spheroids.

Flow Field Analysis of Francis Turbine Draft Tube using POD at Design and Part Load Operating Conditions [PDF]

Journal of Applied Fluid Mechanics
The hydraulic turbines, especially Francis turbines, frequently run at part load (PL) conditions to meet the dynamic energy needs. The flow field at the runner exit changes significantly with a change in the operating point.

Cyclo-Dissipativity Revisited

IEEE Transactions on Automatic Control, 2021
Starting from a symmetrization and extension of the basic definitions and results of dissipativity theory we obtain new results on cyclo-dissipativity; in particular their external characterization and description of the set of storage functions.

Structural development and energy dissipation in simulated silicon apices

Beilstein Journal of Nanotechnology, 2013
In this paper we examine the stability of silicon tip apices by using density functional theory (DFT) calculations. We find that some tip structures - modelled as small, simple clusters - show variations in stability during manipulation dependent on ...

Rail hidden damage detection based on the modal curvature differences method

Advances in Mechanical Engineering
The rail hidden damage includes rail bottom and rail jaw cracks, which cannot be easily detected during the early development stage, and pose a significant danger and risk of rail-breaking accidents. This paper proposed an effective method to detect rail

Blood Coagulation Testing Smartphone Platform Using Quartz Crystal Microbalance Dissipation Method

Sensors, 2018
Blood coagulation function monitoring is important for people who are receiving anticoagulation treatment and a portable device is needed by these patients for blood coagulation self-testing. In this paper, a novel smartphone based blood coagulation test
