This algorithm is deeply rooted in the reproductive dynamics observed in slime molds, particularly the intricate balance these organisms strike between local and global spore dispersal. By replicating this balance, the SMR algorithm deftly navigates between exploration and exploitation phases, aiming to pinpoint optimal solutions across diverse problem domains. For the purpose of evaluation, the SMR algorithm was diligently tested on three engineering problems with inherent constraints: Gear train design, three-bar truss design, and welded beam design. A comprehensive comparative study indicated that the SMR algorithm outperformed esteemed optimization techniques such as Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC), Differential Evolution (DE), Grasshopper Optimization Algorithm (GOA), and Whale Optimization Algorithm (WOA) in these domains. While the exemplary performance of the SMR algorithm is worth noting, it is essential, in line with the No Free Lunch (NFL) theorem, to underscore that the performance of any optimization algorithm invariably depends on the particular problem it addresses. Nevertheless, the SMR algorithm's consistent triumph in benchmark tests underscores its potential as a formidable contender in the vast realm of optimization algorithms. The current exploration not only emphasizes the ever-expanding horizon of bio-inspired algorithms but also positions the SMR algorithm as a pivotal addition to the arsenal of optimization tools. Future implications and the potential scope of the SMR algorithm extend to various domains, from computational biology to intricate industrial designs. Envisioning its broader applicability, upcoming research avenues may delve into refining SMR's core procedures, borrowing insights from a broader range of biological behaviors for algorithmic ideation, and contemplating a binary version of the SMR algorithm, thereby amplifying its versatility in diverse optimization landscapes.","PeriodicalId":40005,"journal":{"name":"Journal of Computer Science","volume":"33 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interpretation and captioning of medical images can be a time-consuming and costly process, often requiring expert support. The growing volume of medical images makes it challenging for radiologists to handle their workload alone. However, addressing the issues of high cost and time can be achieved by automating the process of medical image captioning while assisting radiologists in improving the reliability and accuracy of the generated captions. It also provides an opportunity for new radiologists with less experience to benefit from automated support. Despite previous efforts in automating medical image captioning, there are still some unresolved issues, including generating overly detailed captions, difficulty in identifying abnormal regions in complex images, and low accuracy and reliability of some generated captions. To tackle these challenges, we suggest the new deep learning model specifically tailored for captioning medical images. Our model aims to extract features from images and generate meaningful sentences related to the identified defects with high accuracy. The approach we present utilizes a multi-model neural network that closely mimics the human visual system and automatically learns to describe the content of images. Our proposed method consists of two stages.

The usability of any mobile application is used to find out the user experience of the mobile application by analyzing the user's expectations and preferences. Fuzzy logic always be the optimal choice for quantification. Fuzzy logic-based quantification of usability expectation assesses the user experience of an m-commerce mobile application by taking into account the user's needs, preferences, and expectations. Usability expectation also takes into account the ability of the user to understand and interact with the application, the degree to which the application meets the user's expectations, and the overall satisfaction with the application. This process helps to identify areas of improvement, enabling the developers to make necessary changes for a better user experience. This study presents to design of a usability metric framework and then quantifies the overall usability quality of an m-commerce mobile application with the help of fuzzy logic. The proposed usability metric framework is based on the Goal-Question-Metric (GQM) approach and is intended to provide a comprehensive and systematic approach to design metrics to assess the qualitative aspect of mobile phone applications. The framework has been developed and tested in an m-commerce context and provides a set of measurable criteria to quantify m-commerce mobile applications as per standard. The results of the evaluation can then be used to improve m-commerce mobile applications and to ensure that the user experience is optimized","PeriodicalId":40005,"journal":{"name":"Journal of Computer Science","volume":"24 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alraddadi","doi":"10.3844/jcssp.2024.33.43","DOIUrl":"https://doi.org/10.3844/jcssp.2024.33.43","url":null,"abstract":": There have been increased levels of cybercrime in the database industry, which has hurt the confidentiality, integrity, and availability of these systems. Most organizations apply several security layers to detect and prevent database crimes. For this reason, Database Forensics (DBF) plays a very important role in capturing and discovering, who the criminal is, when the crime was committed, and which part of the database the crime occurred. Several forensic models have been proposed for the DBF field, which can be used to identify, collect, preserve, examine, analyze, and document database crimes. However, most of these models focused on specific database systems due to the variety of the database infrastructure and the multidimensional nature of the database systems. The most important part of the DBF field is the analysis process used to investigate the captured data and discover the attack. Thus, this study proposes an Integrated Reconstruction Investigation Model (IRIM) for database forensics using a metamodeling method. It consists of two main processes: The examining process and the discovering and reporting process. A real scenario has been used to validate the effectiveness of the proposed model. According to the results, the proposed model could detect database cybercrimes and allow domain forensic practitioners to capture and analyze database crimes efficiently.","PeriodicalId":40005,"journal":{"name":"Journal of Computer Science","volume":" 882","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139391774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our approach consists of bringing together several learning methods namely supervised learning, unsupervised learning and reinforcement learning within the same Canvas. The objective is to choose among them the most optimal for classifying and predicting attacks while minimizing the impact linked to the learning costs of these attacks. In our proposed model, we have used a modular design to facilitate the implementation of the intrusion detection engine. The first Meta-learning module is used to collect metadata related to existing algorithmic parameters and learning methods in ML. As for the second module, it allows the use of a cost-sensitive learning technique so that the model is informed of the cost of intrusion detection scenarios. Therefore, among the ML classification algorithms, we choose the one whose automatic learning of intrusions is the least expensive in terms of its speed and its quality in predicting reality. This will make it possible to control the level of acceptable risk in relation to the typology of cyber-attacks. We then simulated our solution using the Weka tool. This led to questionable results, which can be subject to the evaluation of model performance. These results show that the classification quality rate is 93.66% and the classification consistency rate is 0.882 (close to unit 1). This proves the accuracy and performance of the model.","PeriodicalId":40005,"journal":{"name":"Journal of Computer Science","volume":"99 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139128715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These networks host a name server that manages the Domain Name System (DNS) records of the websites on a network of compromised machines with frequently changing IP addresses. As a result, blacklisting the machines has less impact on stopping the services, lengthening their lifespan and that of the websites they support. High detection delays and the use of fewer, lesser varied detection features limit the proposed solutions for identifying the websites hosted in these networks, making them more susceptible to detection evasions. This study suggests a novel set of highly diverse features based on DNS, network, and host behaviors for fast and highly accurate detection of phishing websites hosted in NSIFNs using a Machine Learning (ML) approach. Using a variety of traditional and deep learning ML algorithms, the prediction performance of our features was assessed in the context of binary and multi-class classification tasks. Our approach achieved optimal accuracy rates of 98.59% and 90.41% for the binary and multi-class classification tasks, respectively. Our approach is a crucial step toward monitoring NSIFN components to mitigate phishing attacks efficiently.","PeriodicalId":40005,"journal":{"name":"Journal of Computer Science","volume":"85 23","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
