Influence Functions of a Point Force for Kirchhoff Plates with Rigid Inclusions

Journal of Mechanics, 2004
AbstractA semi-analytic method is proposed for two problem settings for a Kirchhoff plate containing an absolutely rigid circular inclusion and undergoing a transverse point force. The settings differ by the location (within and out of inclusion) of the force application point. In both cases, the plate's stress-strain state is simulated with a boundary

Neural network with signal parameters featuring for near‐surface velocity model building

Near Surface Geophysics, EarlyView.
Abstract This study presents a method that integrates spectral recomposition (SR) with a neural network to improve near‐surface seismic analysis. The approach incorporates SR‐derived wavelet‐timing attributes into a fully convolutional network (FCN) to enhance the characterization of shallow subsurface structures. Field evaluation was conducted using S‐

Global solvability for Kirchhoff equation in special classes of non-analytic functions

Journal of Differential Equations, 2006
This paper represents a generalization of \textit{R. Manfrin}'s results, see [J. Differ. Equations 211, No. 1, 38-60 (2005; Zbl 1079.35074)], devoted to solvability of the Cauchy problem for the Kirchhoff equation: \[ u_{tt}-a(t)\Delta u=0,\,(x,t)\in[0,T]\times \mathbb R^n; \] \[ u(0,x)=u_0(x),\,u_t(0,x)=u_1(x),\,x\in \mathbb R^n, \] where \[ a(t ...

Towards Artificial Intelligence Hardware With 3D Integrated Ferroelectric Transistors

Small, EarlyView.
Modern AI workloads demand hardware that mitigates the data‐movement bottleneck of von Neumann architectures. Here, we demonstrate a 4‐tier monolithic 3D (M3D) platform vertically integrating IGZO access transistors with Hf₀.5Zr₀.5O2 ferroelectric FETs.

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

Wildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

Mixed Super‐Circles

Computer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

‘Being an Outsider’ and ‘Being an Insider’: A Focused Ethnography of Family Members' Visitation Experiences in an Adult ICU

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims To explore how the restricted visitation policy impacts family members' visitation experiences and perceptions in an adult intensive care unit (ICU). Design Focused ethnography. Methods Data collection included 39 observation sessions (totalling 65.3 h), 19 semi‐structured interviews with family members, and document analysis of policies ...

General decay for the viscoelastic wave equation for Kirchhoff-type containing Balakrishnan-Taylor damping, nonlinear damping and logarithmic source term under acoustic boundary conditions

Boundary Value Problems
In this paper, we study the general decay result of the viscoelastic wave equation of Kirchhoff-type with Balakrishnan-Taylor damping, weakly nonlinear time-dependent damping, and a logarithmic source term under acoustic boundary conditions. Our analysis

Functional morphology of trabecular bone in the calcaneus of African apes

Journal of Anatomy, EarlyView.
Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

A note on nonlocal discrete problems involving sign-changing Kirchhoff functions

Opuscula Mathematica
<jats:p>In this note, we establish a multiplicity theorem for a nonlocal discrete problem of the type \[\begin{cases} -\left(a\sum_{m=1}^{n+1}|x_m-x_{m-1}|^2+b\right)(x_{k+1}-2x_k+x_{k-1})=h_k(x_k), &k=1,\ldots ,n, \\ x_0=x_{n+1}=0 \end{cases}\] assuming \(a\gt 0\) and (for the first time) \(b\gt 0\).</jats:p>
