The continuous and exponential growth in scientific publications poses a challenge in manually sorting and searching for specific topics within a university's publications. Recent advancements in artificial intelligence, natural language processing, and clustering methods, particularly the K-Means, have shown satisfactory performance in handling large volumes of textual data. Furthermore, topic modeling methods, notably praised for their effectiveness in organizing textual documents. This study focuses on evaluating the performance of the K-Means and Latent Dirichlet Allocation in clustering Sebha University scientific publications. Different term weighting is employed namely term frequency inverse document frequency, and Word2Vec to represent the tokens. K-Means demonstrated notable performance when coupled with Word2vec, as indicated by metrics such as the Davies-Bouldin Index, Silhouette Score, Calinski-Harabasz Index, and Inertia. The best performance was observed when using term frequency inverse document frequency with the Entropy metric. The evaluation metrics for K-Means did not unanimously agree on the optimal number of clusters. In contrast, Latent Dirichlet Allocation consistently performed well, with all measurements agreeing on the best results with the smallest number of clusters. Among the various combinations tested, Latent Dirichlet Allocation paired with Word2vec produced the best results across metrics, demonstrating superior cohesion strength through the topic coherence metric and minimizing noise aggregates based on the entropy metric. © 2024 IEEE.

Cross-2D-to-3D (2D-3D) heterogeneous palmprint recognition aims to matching a 2D palmprint probe with the 3D palmprint galleries, which shows great potential for biometric applications due to rich information of 3D images and the low-cost of 2D image acquisition. However, the large structural discrepancy between 2D and 3D palmprint images makes it hard to directly conduct matching between 2D-3D heterogeneous palmprint images. In this paper, we propose a palmprint image generative adversarial network (PIGAN) to convert 2D palmprint images into 3D domain for 2D-3D heterogeneous palmprint recognition. We first calculate the mean curvature images (MCIs) to present the 3D palm surface measurements of 3D palmprint images. Then, we employ an image-to-image generation backbone to transform 2D palmprint images into 3D MCI representations. To make the fake MCIs realistic, we impose both adversarial and identity-aware learning losses to protect the discriminative information of MCIs, and further introduce a visual-recovery loss to restore the visual-specific texture characteristics of palmprints. By this way, high-quality 3D palmprint MCI can be synthesized with high similarity as the real ones at both feature and visual levels, such that the pixel-level gap between 2D and 3D palmprint images can be effectively reduced for 2D-3D heterogeneous palmprint recognition. Extensive experimental results on the widely-used PolyU 2D-3D palmprint database clearly show the effectiveness of the proposed PIGAN in improving the performance of 2D-3D heterogeneous palmprint recognition. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Preservation of the crops depends on early and accurate detection of pests on crops as they cause several diseases decreasing crop production and quality. Several deep-learning techniques have been applied to overcome the issue of pest detection on crops. We have developed the YOLOCSP-PEST model for Pest localization and classification. With the Cross Stage Partial Network (CSPNET) backbone, the proposed model is a modified version of You Only Look Once Version 7 (YOLOv7) that is intended primarily for pest localization and classification. Our proposed model gives exceptionally good results under conditions that are very challenging for any other comparable models especially conditions where we have issues with the luminance and the orientation of the images. It helps farmers working out on their crops in distant areas to determine any infestation quickly and accurately on their crops which helps in the quality and quantity of the production yield. The model has been trained and tested on 2 datasets namely the IP102 data set and a local crop data set on both of which it has shown exceptional results. It gave us a mean average precision (mAP) of 88.40% along with a precision of 85.55% and a recall of 84.25% on the IP102 dataset meanwhile giving a mAP of 97.18% on the local data set along with a recall of 94.88% and a precision of 97.50%. These findings demonstrate that the proposed model is very effective in detecting real-life scenarios and can help in the production of crops improving the yield quality and quantity at the same time.

Soldering irons are a hand tool that is indispensable in the process of making small series of electronic devices. Soldering irons have evolved from very simple devices without temperature control to devices with complex temperature control. The implementation of temperature control is based on the knowledge of the thermal models of the soldering iron. Thermal models of soldering irons are based either on the theory of thermal fields or on the theory of equivalent Kirchhoff thermal circuits. The theory of thermal fields is applied for very accurate modeling. In doing so, the finite element method (FEM) is used. For the above, it is necessary to use software packages based on FEM. Unlike FEM-based modeling, thermal circuit modeling does not require specialized software tools. It is also possible to derive analytical expressions that describe the thermal process of the soldering iron. In this paper, a thermal model of a soldering iron based on equivalent Kirchhoff thermal circuits is presented. Analytical expressions were derived to describe the thermal transient. The validity of the theoretical model is supported by measurement. Measurements were carried out on two soldering irons from different manufacturers. The measurement results were analyzed. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

The increasing global population and reliance on electrical devices for daily life resulted in sharply rising energy consumption. Also, this leads to higher household electricity bills. As a result, there is a growing demand for energy monitoring systems that can accurately estimate energy usage to help save power, especially for older home appliances that are difficult or expensive to update with monitoring sensors. However, current energy monitoring systems have some drawbacks, such as the inability to detect different types of appliances and the deployment complexity. Moreover, such systems are too costly to use in older power infrastructures. To address this issue, we proposed a centralized smart energy monitoring system designed for legacy home appliances, aiming to address the limitations of current energy monitoring systems by avoiding costly infrastructure upgrades to calculate the power consumption of legacy home appliances. The proposed system employs a two-layered architecture comprising hardware (Emontx device, Analog-to-Digital Converters (ADC), and Current Transformer (CT) sensors) and a software layer that includes Artificial Intelligence (AI) predictors using a pre-defined set of rules and K Nearest Neighbours (KNN) algorithms. We conducted three experiments on real home appliances to evaluate the proposed work. The accuracy of the proposed system showed positive results after several modifications and hard tuning of several parameters in devices, specifically for Jordanian power plants. © The Author(s) 2024.

The Internet of Things (IoT) is a form of Internet-based distributed computing that allows devices and their services to interact and execute tasks for each other. Consequently, the footprint of the IoT is increasing and becoming more complex to the highest degree. This has also given birth to new IoT-enabled applications and services. Efficient service interaction and management also call for understanding and analyzing the nature of IoT services. Further, IoT services must be characterized into various classes, and different service-related attributes must be considered for the classification. This article assesses the requirements of heterogeneous IoT services by examining their interactions. Principally, heterogeneous IoT and their service interactions are targeted. The research work performs classification of IoT services into various classes. Services are classified on the basis of various attributes. The attributes reflect different characteristics of the services. This research enables improved utilization of IoT services through efficient classification of available resources using machine learning methods. To demonstrate service classification applicability, the SVM, voting classifier, and decision tree have been applied in a service-oriented environment along with different types of services. All the services in the data set were analyzed and divided into five classes. Moreover, the decision tree performed well and achieved higher accuracy values in all classes. However, the overall prediction and classification of the decision tree model were observed to be good and satisfactorily high. © 2013 IEEE.

ChatGPT is a language model that has been developed by Open AI. It has the ability to answer any question raised by a participant in a form of conservation. ChatGPT takes advantages of the effective transformers architecture to generate text discussions that are relevant and perceptive. Although ChatGPT was initially trained on English text data, it has also been fine-tuned on other languages including Spanish, French, Chinese, German and Arabic. ChatGPT has been employed in different NLP domains for English language, but specifically it is still slightly limited in languages other than English. In this research, we assess ChatGPT in extracting active participle (ism al-fa’il) and passive participle (ism al-maf’uul) from Arabic verbs of base forms (alfilu alsahih) and verbs with vowels (alfilu almutal) to help the non-native speakers who find it difficult to extract these participles and try to use ChaTGPT as a learning tool and get inaccurate responses. We experiment ChatGPT’s performance in zero-shot learning then with a wide range of prompt templates as well as few-shot learning. The results show a greet enhancement in the ChatGPT performance when tuning the rule-based prompts with k-shot examples especially for passive participle extraction. ChatGPT performed well in extracting participles from verbs without vowels, but after training with k-shot samples, it improved by 6% for active participles and 25% for passive participles. Additionally, extracting passive participles for verbs with vowels significantly improves performance compared to extracting active participles, especially the case when the vowels exist at two positions, which results in a 100% improvement. The performance of ChatGPT improved in extracting active participle for verbs with no vowels by 6% and passive participles by 25%. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2024.

This paper proposes a novel approach that combines the YOLOv8 object detection model with the Dark Channel Prior (DCP) algorithm to improve car license plate detection in foggy weather conditions. The proposed approach consists of two stages: the first stage is data preprocessing with the DCP approach, and the second stage is image preprocessing. The DCP model is trained to detect the license plates in the enhanced images, providing the final output of the proposed method. The experimental findings show that the suggested strategy significantly boosts detection accuracy and improves license plate visibility compared to conventional methods. Moreover, the integration of DCP with Yolov8 resulted in robust performance against fog, achieving an average precision of 0.975. © 2024 IEEE.
