The Synthesis, Structural Characterization and Superconductivity of $FeSe_x$ with $0.80 \leq x \leq 1.20$

open access: yesJournal of Atomic and Molecular Sciences, 2012
We have performed a detailed study on the synthesis, the characterization of structural phases and superconductivity of the binary FeSex system from the Fe-rich phase into the Se-rich phase with 0.80≤ x≤1.20. The results indicate that by long-time low- temperature annealing, single phase sample could be obtained near the composition of FeSe 0.95 with ...

Sound Level Measurement, Monitoring and Management in Small Music Venues: Leq Averaging Time Interval [PDF]

open access: yes
This paper considers different Leq averaging time intervals and their effect on the dynamic range of live music as presented to an audience. Data was collected in four small and mid-sized music venues in Perth, Australia in 2019, and combined with an ...

Maximum size of $C_{\leq k}$-free strong digraphs with out-degree at least two [PDF]

open access: yes, 2022
Let $\mathscr{H}$ be a family of digraphs. A digraph $D$ is \emph{$\mathscr{H}$-free} if it contains no isomorphic copy of any member of $\mathscr{H}$. For $k\geq2$, we set $C_{\leq k}=\{C_{2}, C_{3},\ldots,C_{k}\}$, where $C_{\ell}$ is a directed cycle ...

Bayesian Optimization–Reinforcement Learning Hybrid Framework for a‐IGZO Thin‐Film Transistor Compact Model Parameter Extraction in 2T0C Dynamic Random Access Memory Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
A training‐free two‐stage BO–RL framework extracts compact model parameters for a‐IGZO TFTs, reaching BO‐level fitting quality at a constant per‐simulation optimization cost. Bayesian optimization performs exploration and provides an optimized starting point.

Vision‐Based Tactile Finger Integrating Fingerpad and Nail Sensing for Robotic Manipulation

open access: yesAdvanced Intelligent Systems, EarlyView.
This vision‐based tactile finger captures nail force and fingerpad force, contact position, and in‐plane orientation with one internal camera. An external camera recognizes the target and presets finger inclination from object height. The compact dual‐sensing design supports tactile‐guided table contact and reliable grasping of objects ranging from ...

Ein Projekt zur Re-Analyse von Fluglärm-Belästigungsdaten: Leq+X

open access: yes, 2018
In der jüngeren Vergangenheit haben mehrere Veröffentlichungen gezeigt, dass die Belästigung der Bevölkerung durch den Lärm von Verkehrsflughäfen bei vergleichbaren Dauerschallpegeln über die Jahre gestiegen ist.

Crease‐Encoded Soft Origami Chambers: A Unified Design‐to‐Fabrication Framework for Low‐Pressure Pneumatic Joints

open access: yesAdvanced Intelligent Systems, EarlyView.
Origami turns a single silicone chamber into three different soft fluidic actuators. Crease angles alone decide whether it elongates, bends, or twists, and the fully folded chambers are cast monolithically in one day. Below 15 kPa, they reach 268% axial stretch, 72° bending, and 55° twist—no strain‐limiting layers, no rigid reinforcements, no vacuum ...

Positive solutions of a nonlinear higher order boundary-value problem

open access: yesElectronic Journal of Differential Equations, 2007
The authors consider the higher order boundary-value problem $$displaylines{ u^{(n)}(t)= q(t)f(u(t)), quad 0 leq t leq 1, cr u^{(i-1)}(0) = u^{(n-2)}(p) = u^{(n-1)}(1)=0, quad 1 leq i leq n-2, }$$ where $nge 4$ is an integer, and $pin(1/2,1)$ is a ...
