    Abstract In this study, thin films of titanium dioxide (TiO2) were deposited onto glass and indium tin oxide (ITO) substrates at room temperature, using plasma-assisted pulsed DC sputtering with a 99.9% pure stoichiometric TiO2 target. Our research aims to investigate the influence of film thickness on the optical, structural, and morphological properties of TiO2 nanostructured thin films, as well as its impact on the photovoltaic performance of heterojunctions where TiO2 serves as the emitter. Using advanced PRISA software, parameters such as refractive index, film thickness, and band gap energy were determined. Spectrophotometry analysis shows that TiO2 thin film samples More > Graphic Abstract

    Ye Tan1,2, Jing Ling3,4,5, Zewen Chen3,4,5, Runzhang Liang3,4,5, Shusheng Wen3,4,5, Yong Zhang3,4,5,*

    Structural and Congenital Heart Disease, Vol.21, No.3, 2026, DOI:10.32604/schd.2026.077197 - 31 July 2026

    Abstract Background: Congenital left ventricular diverticulum is an uncommon cardiac malformation that may present with chest pain, ventricular arrhythmia, thromboembolism, or rupture risk depending on lesion morphology and wall composition. Case description: We report an adolescent male with chest pain and frequent premature ventricular complexes who was found to have a giant apical left ventricular diverticulum with marked wall thinning and regional hypokinesia. Multimodality imaging, including transthoracic echocardiography, computed tomography, cardiac magnetic resonance, and myocardial perfusion/metabolic assessment, supported the diagnosis of a fibrous diverticulum and helped exclude ischemic myocardial injury. To refine operative planning, patient-specific dynamic three-dimensional (3D)… More >

    Coupled Modeling of CO2 Frosting, Fluid Flow, and Heat Transfer under Cryogenic Conditions Using a Nucleation-Based CFD Framework

    Xuewen Cao*, Zhe Chen, Gaoya Ding, Wei You

    FDMP-Fluid Dynamics & Materials Processing, Vol.22, No.7, 2026, DOI:10.32604/fdmp.2026.080209 - 31 July 2026

    Abstract A two-dimensional Computational Fluid Dynamics (CFD) model, grounded in classical nucleation theory, is developed to investigate CO2 frosting and the associated heat transfer under cryogenic conditions. The model integrates gas–solid phase-change kinetics with multiphysics transport equations to capture the coupled phenomena governing frost formation. The Peng–Robinson equation of state is employed to predict CO2 frost points in binary mixtures, with model predictions validated against experimental data, yielding errors in frost thickness and thermal conductivity below 15%. The results demonstrate that decreasing the cryogenic wall temperature from 160 K to 150 K increases the average frost thickness… More >

    Intra-Modal Feature Translation for Robust Kinematic Modeling in Wearable Health Applications

    Ashwin Sankaran*

    Journal on Artificial Intelligence, Vol.8, pp. 403-423, 2026, DOI:10.32604/jai.2026.080854 - 29 July 2026

    Abstract Human Motion Kinetics Recognition (HMKR) plays a pivotal role in advancing intelligent monitoring systems for public safety, machine interaction, and elderly-care technologies. Despite the increasing availability of affordable Inertial Measurement Units (IMUs), achieving accurate full-body motion analysis remains challenging due to sensor noise and variability across real-world environments. Addressing these limitations requires robust processing strategies capable of handling complex inertial time-series data. This research introduces an optimized HMKR system that leverages a comprehensive pipeline focusing on inertial sensor time-series data. In this research, we introduce an HMK-based recognition system that primarily focuses on six-degree-of-freedom (6-DoF) More >

    A New Hybrid Framework Based on Grey and Neuro-Fuzzy Inference System for Energy Demand Forecasting in Vietnam

    Xuan Kien Pham1, Van Dat Nguyen2,*, Van Thanh Phan3,*, Duc Trien Nguyen4,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.086196 - 27 July 2026

    Abstract Accurate energy consumption forecasting faces two major challenges: limited historical data and complex consumption patterns. To address these challenges, this study proposes a new hybrid framework named the Decomposition-based Grey-Neuro-Fuzzy Architecture (DeGNA). The model first uses the Denton method to convert limited annual records into high-frequency monthly data. Next, it applies STL decomposition to separate the data into trend, seasonal and residuals components. A rolling-window GM(1,1) model is then used to predict the main growth trend, while a GWO-optimized ANFIS model uses economic indicators (IIP and FDI) to forecast complex seasonal changes. This study evaluates… More >

    Modeling Time-Aware Mobile Robot Navigation by Learning Subjective Time Maps (STM)

    Adrián Bañuls-Arias, Cipriano Galindo, Ana Cruz-Martín, Manuel Castellano-Quero, Juan M. Gandarias, Juan-Antonio Fernández-Madrigal, Vicente Arévalo-Espejo*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.085976 - 27 July 2026

    Abstract The basic operation of a mobile robot is navigating to some target, avoiding collisions and possibly minimizing other criteria. A diversity of methods have been developed since the past century, and the research is still active, but there is one aspect that is often neglected: the duration of the steps in which computational devices divide the navigation process. Usually, it is set heuristically to a small, constant value for sampling observations frequently enough to ensure safety; however, each robot and environment has particularities that can make such a fixed timestep sub-optimal under some criteria.

    LLM-Driven Cross-Flow Modeling for Network Attack Traffic Detection

    Aoran Huang1,2,*, Sinuo Zhang1,2, Haoxiang Zhu1,2, Xiaojing Fan1,2, Huachun Zhou1,2,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.083972 - 27 July 2026

    Abstract In Future Mobile Internet and convergence application scenarios, existing network attack traffic detection methods are insufficient in characterizing cross-flow correlations and structural dependencies during the attack process, and therefore still have limited generalization ability in complex scenarios and unknown attack identification tasks. To address this issue, this paper proposes a cross-flow modeling large language model framework, which extends the traditional detection paradigm based on single-flow features to joint modeling oriented toward cross-flow context and relational structure. Specifically, this paper constructs cross-flow context through flow sorting, grouping, and cross-group sampling, and combines an inter-flow relation matrix… More >

    A Machine Learning Surrogate Framework for Bayesian Calibration of Nonlinear Concrete Damage Models

    Yi Chen, Xiaodan Ren*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.083966 - 27 July 2026

    Abstract Concrete exhibits significant stochasticity and nonlinearity, making the calibration of nonlinear damage models challenging for high-precision structural analysis. To address the high computational cost of finite element model calibration and the influence of model bias, this study proposes a machine learning surrogate framework for Bayesian calibration of nonlinear concrete damage models. The framework integrates a bi-scalar damage constitutive model, support vector regression based surrogate modeling, response-level finite element model bias representation, and adaptive Markov Chain Monte Carlo sampling within a unified probabilistic setting. The surrogate models are constructed to approximate the nonlinear mapping from constitutive… More >

    Analytical Modeling of Transcoding Artifacts for Detecting SIMBox-Routed Calls

    Hyunghoon Kim1, Wonsuk Choi2, Kyungho Joo3,*, Hyojin Jo1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.083948 - 27 July 2026

    Abstract As mobile networks evolve toward next-generation architectures in which cellular and IP-based voice services are increasingly converged, SIMBox-based call routing has emerged as an important issue in modern telecommunication networks. By converting Voice over IP (VoIP) traffic into local cellular calls, SIMBox appliances allow IP-originated calls to appear as domestic cellular calls. Although SIMBox usage is not inherently fraudulent, detecting SIMBox-routed calls is important for identifying abnormal call-routing behavior and supporting network-side and client-side security applications. In this paper, we propose a client-side framework for SIMBox-routed call detection. Calls routed through SIMBox infrastructure are identified… More > Graphic Abstract
