Deep bed filtration model for cake filtration and erosion

Many phenomena in nature and technology are associated with the filtration of suspensions and colloids in porous media. Two main types of particle deposition,namely, cake filtration at the inlet and deep bed filtration throughout the entire porous medium, are studied by different models. A unified approach for the transport and deposition of particles based on the deep bed filtration model is proposed. A variable suspension flow rate, proportional to the number of free pores at the inlet of the porous medium, is considered. To model cake filtration, this flow rate is introduced into the mass balance equation of deep bed filtration. For the cake filtration without deposit erosion,the suspension flow rate decreases to zero, and the suspension does not penetrate deep into the porous medium. In the case of the cake filtration with erosion, the suspension flow rate is nonzero, and the deposit is distributed throughout the entire porous medium. An exact solution is obtained for a constant filtration function. The method of characteristics is used to construct the asymptotics of the concentration front of suspended and retained particles for a filtration function in a general form. Explicit formulae are obtained for a linear filtration function. The properties of these solutions are studied in detail.

Foundation models(FMs) [1] have revolutionized software development and become the core components of large software systems. This paradigm shift, however, demands fundamental re-imagining of software engineering theories and methodologies [2]. Instead of replacing existing software modules implemented by symbolic logic, incorporating FMs' capabilities to build software systems requires entirely new modules that leverage the unique capabilities of ***, while FMs excel at handling uncertainty, recognizing patterns, and processing unstructured data, we need new engineering theories that support the paradigm shift from explicitly programming and maintaining user-defined symbolic logic to creating rich, expressive requirements that FMs can accurately perceive and implement.

Neutrosophic Fuzzy Power Management (NFPM): Tackling Uncertainty in Energy Harvesting for Sensor Networks

引用

Neutrosophic Sets and Systems 2025年 76卷 99-114页

This paper presents a novel approach known as Neutrosophic Fuzzy Power Management (NFPM) aimed at addressing the critical challenge of uncertain energy availability in Energy Harvesting Sensor Networks (EHWSNs). The main objective of this research is to enhance the management of energy resources within these networks, which traditional fuzzy logic methods often fail to do, leading to power failures and reduced reliability. NFPM utilizes neutrosophic logic to effectively model uncertainty by representing the degrees of truth, indeterminacy, and falsity of both harvested and residual energy levels. Through a fuzzy inference system, NFPM dynamically allocates energy budgets for each time slot based on these neutrosophic sets, resulting in more adaptive and conservative energy distribution. The results are validated through numerical examples and extensive simulations, demonstrating NFPM's superiority over traditional fuzzy logic, with significant improvements such as a 25% reduction in power failures, 95% enhanced network connectivity, a 15% increase in data transmission success rates, and overall improvements in energy efficiency and robustness to fluctuations and noise. This research establishes NFPM as a promising solution to the uncertainties inherent in EHWSNs. Future research directions include exploring the integration of NFPM with machine learning algorithms for predictive energy management, assessing its scalability in larger networks, and examining its applicability in other domains requiring energy management under uncertainty. © 2025, University of New Mexico.

Text Analysis Using Morphological Operations on a Neutrosophic Text Hypergraph

Neutrosophic Sets and Systems 2023年 61卷 337-364页

Due to the rise in the operation of platforms on social media, there is more opportunity for users to post content online, out of which some tend to be hate speech. Hate speech is found in almost all domains like sports, politics, religion, government affairs, and personal matters. Its detection and removal from platforms like Twitter, Facebook, etc. are tedious. Over the years, a lot of methods have evolved in this area most of which are more time-consuming machine learning methods. Our objective is to find a better method that considers indeterminacy at the word level and sentence level for the detection and removal of hate speech using fuzzy logic applied to Neutrosophic hypergraphs. A neutrosophic hypergraph is a kind of hypergraph where each node and hyperedge has three associated membership functions namely Indeterminacy, Truth and Falsity. Our work has successfully modeled Text documents into neutrosophic hypergraphs and morphological operators like dilation, erosion etc. are applied to it. Using these operations further operators like thinning, thickening, hit-or-miss, and skeletoning are applied. Finally hate speech is identified and removed. This a novel method in this area. The system is tested with Twitter tweets and the results are promising with an accuracy of 88%. © (2023), (University of New Mexico). All Rights Reserved.

Effective MLP and CNN based ensemble learning for speech emotion recognition

引用

Multimedia Tools and Applications 2024年第36期83卷 83963-83990页

Speech emotion recognition (SER) is one of the most important and active areas of. research in speech processing. Numerous approaches have been proposed to address various limitations in this field, but the sheer diversity of speech emotions, as well as their complexity, continue to make SER a tough nut to crack. This paper attempts to conduct a thorough investigation into speech emotion recognition in order to determine the most appropriate feature set and model for SER. A multi-layer perceptron (MLP) and convolutional neural network (CNN) based ensemble model for SER is proposed, which is a simple yet very powerful model for SER that can greatly improve classification accuracy. The model’s performance is evaluated based on four benchmark datasets, namely RAVDESS (Ryerson Audio-Visual Database of Emotional Speech and Song), EmoDB (Emotional Dat0abase), SAVEE (Surrey Audio-Visual Expressed Emotion), and TESS (Toronto Emotional Speech Set). The proposed model dominates over several baseline methods (decision tree (DT), random forest (RF), support vector machine (SVM), k-nearest neighbour (KNN), and the base learners, i.e., MLP and CNN) in terms of various performance metrics for all the datasets. Furthermore, the proposed model outperforms all previous works for RAVDESS (Acc=73.1%), SAVEE (Acc=83.8%), and TESS (Acc=99.9%) datasets. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.
