Application of land-use regression models to estimate sound pressure levels and frequency components of road traffic noise in Taichung, Taiwan

Environment International, 2019
Few studies have applied land-use regression to predict road traffic noise exposure, and there are few predictive models for different frequencies. This study aimed to measure 24-h average road traffic noise levels and to analyze the frequency components

Comparative Analysis of Model‐Agnostic Explanation Methods in Materials Science

Advanced Intelligent Systems, EarlyView.
To address the critical lack of explainable artificial intelligence (XAI) benchmarks in materials science, we present a quantitative and qualitative analysis of six XAI methods applied to molecular fingerprints. Our results reveal significant discrepancies in feature importance rankings, demonstrating that the chosen explanation approach introduces ...

Existence of three solutions for a two-point singular boundary-value problem with an unbounded weight

Electronic Journal of Differential Equations, 2016
We show the existence of three solution for the singular boundary-value problem $$\displaylines{ -z'' = h(t) \frac{f(z)}{z^\beta} \quad \text{in } (0,1) ,\cr z(t)> 0 \quad \text{in } (0,1),\cr z(0)= z(1)=0 , }$$ where $ 0 < \beta 0$ and ...

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

Journal 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 ...

Benchmarking Data‐Driven Control of Octopus‐Inspired Soft Arms in Underwater Environment

Advanced Intelligent Systems, EarlyView.
Underwater soft robots present safe, compliant interaction, yet reproducible control remains scarce. This work presents an open benchmark for octopus‐inspired arms: a smooth, velocity‐diverse data‐collection scheme produces a compact dataset to train a vanilla policy.

Exploiting Edge Semantics in Job Shop Scheduling Problem With Heterogeneous Graph Transformers

Advanced Intelligent Systems, EarlyView.
A heterogeneous graph transformer (HGT) is introduced for reinforcement learning‐based job shop scheduling by explicitly distinguishing precedence and machine‐contention relations through edge‐type‐specific attention. The proposed framework learns richer scheduling representations, improves decision quality over homogeneous graph models, and highlights

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

Advanced 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.

Positive solutions of a nonlinear higher order boundary-value problem

Electronic 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 ...

The $(\leq 6)$-half-reconstructibility of digraphs

, 2013
Let $G=(V,A)$ be a digraph. With every subset $X$ of $V$, we associate the subdigraph $G[X]=(X,A\cap (X\times X))$ of $G$ induced by $X$. Given a positive integer $k$, a digraph $G$ is $(\leq k)$-half-reconstructible if it is determined up to duality by its subdigraphs of cardinality $\leq k$. In 2003, J.

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

Advanced 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 ...
