A Methodology to Analyze Students' Comics Created in the Context of Science Inquiry in Secondary Education Reveals Their Modes of Reasoning

open access: yesJournal of Research in Science Teaching, EarlyView.
ABSTRACT This article introduces a methodology for analyzing comics drawn by students in the context of a science inquiry. Within a pragmatist situated semiotic approach, comics created by the students in the context of a science inquiry are semiotic representations reflecting learning viewed as a sense‐making inferential process via the building of a ...

Nonexistence of solutions to some inequalities and systems with singular coefficients on the boundary

open access: yesElectronic Journal of Differential Equations, 2017
We obtain sufficient conditions for the nonexistence of positive solutions to some elliptic inequalities and systems containing the p-Laplace operators and coefficients possessing singularities on the boundary.

Solutions to semilinear elliptic PDE's with biharmonic operator and singular potential

open access: yesElectronic Journal of Differential Equations, 2016
We study the existence and nonexistence of positive solution to the problem $$\displaylines{ \Delta^2u-\mu a(x)u=f(u)+\lambda b(x)\quad\text{in }\Omega,\cr u>0 \quad\text{in }\Omega,\cr u=0=\Delta u \quad\text{on }\partial\Omega, }$$ where $\Omega$

A Detailed and Comprehensive Account of Fractional Physics‐Informed Neural Networks: From Implementation to Efficiency

open access: yesArtificial Intelligence for Engineering, EarlyView.
Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.

Nonexistence of solutions to systems of higher-order semilinear inequalities in cone-like domains

open access: yesElectronic Journal of Differential Equations, 2002
In this paper, we obtain nonexistence results for global solutions to the system of higher-order semilinear partial differential inequalities $$displaylines{ frac{partial^k u_i}{partial t^k}-Delta (a_i (x,t) u_i (x,t)) geq t^{gamma_{i+1}}|x|^{sigma_{i+1}}

Exploration and Exploitation: A Study on Sample Efficiency in Reinforcement Learning With Multifaceted Curiosity Rewards and Adaptive Experience Replay Utilisation in Sparse Reward Environments

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT In recent years, the widespread application of deep reinforcement learning (DRL) in autonomous systems has highlighted the importance of achieving high sample efficiency under sparse reward conditions. To improve sample efficiency in sparse reward environments, this paper proposes a reinforcement learning framework built upon the Soft Actor ...

Task‐Aligned Haze Removal With Semantic‐Aware Fusion and Contrast Self‐Correction

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Adverse haze conditions introduce complex degradations that obscure scene details and distort structural cues critical for object detection, posing persistent challenges for vision‐based sensing systems. Although existing haze removal methods have achieved notable improvements in visual clarity, their optimisation objectives are often ...
