Recognizing the unique challenges this community faces—such as the scarcity of sign language interpreters, particularly in remote areas, and the lack of real-time translation tools. This paper proposes the development of a smartphone-runnable sign language recognition model to address the communication problems faced by deaf and hard-of-hearing persons. This proposed model combines Mediapipe hand tracking with particle filtering (PF) to accurately detect and track hand movements, and a convolutional neural network (CNN) and bidirectional long short-term memory based gesture recognition model to model the temporal dynamics of Sign Language gestures. These models use a small number of layers and filters, depthwise separable convolutions, and dropout layers to minimize the computational costs and prevent overfitting, making them suitable for smartphone implementation. This article discusses the existing challenges handled by the deaf and hard-of-hearing community and explains how the proposed model could help overcome these challenges. A MediaPipe + PF model performs feature extraction from the image and data preprocessing. During training, with fewer activation functions and parameters, this proposed model performed better to other CNN with RNN variant models (CNN + LSTM, CNN + GRU) used in the experiments of convergence speed and learning efficiency.</p>","PeriodicalId":14463,"journal":{"name":"International Journal of System Assurance Engineering and Management","volume":"130 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190403","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}

A SAST tool called SonarQube which can scan source code of an application and identify the vulnerabilities present in software. It can also find the RCA of the vulnerabilities found in software products. it helps in rehabilitating the securities flaws found in analysis of the software products. SAST tools analyses upside-down for an application. It does not need s system to be in running state to perform analysis. The scan provides instant feedback to developers in terms of reducing security risks for an application. It helps to resolve issues which was present during development and helps developers to increase their knowledge. As a result, developers become competent about knowledge of security for software product. The sonar analysis report provides on demand access to all recommendations. The user can navigate to line-of-code which have vulnerabilities and they can do faster discovery and auditing. And hence the developers can write more code which is less vulnerable. This way they have more secure and quality product delivered. To conduct static analysis, the Authors have used SonarQube as a tool, which compile and measure the code quality for the code kept in repositories. The Authors observed SAST is important step in conductingsecurity and vulnerabilities scan for software product, it was also observed that most of the organisationconduct this SAST at later stage in DevOps/DevSecOps Phase which actually increases pipeline execution time. This motivated Authors topropose a better Model to reduce the build pipeline execution time. As Devops/DevSecOps standards, SonarQube is used to do SASTin DevSecOps pipelines which normally increases the build pipeline execution time. This increases the effort and time to complete the build pipeline and hence it also impacts overall budget of the software product. In the proposed solution, the Authors tried to reduce build pipeline execution time by conducting static analysis early in DevSecOps phases using shift left. Proposed solution uses GitHub open-source project written in C#.NET language, Azure Devops, dotnet sonar scanner tool and SonarQube to conduct static analysis and testing. The authors(s) tried to enhance the software quality in early Devops phases which will be helpful in reducing the build time and cost. Proposed Model will be helpful in increasing reliability, efficiency, and performance of software product.</p>","PeriodicalId":14463,"journal":{"name":"International Journal of System Assurance Engineering and Management","volume":"50 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141190712","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}

This strategy is presented as an innovative way to handle the problem. Two key modifications are involved in the implementation of our method: firstly, the accurate tuning of the transform coding threshold in compressive sensing to achieve effective data compression, and secondly, the intelligent control of the number of parity checks in LDPC coding to reduce both energy consumption and latency. These adaptive techniques are tailored to meet the signal-to-noise ratio estimates and the dependability standards unique to the application. Our findings demonstrate a substantial accomplishment, with a remarkable 4.2% reduction in power consumption compared to other methods currently in use.

In addition, a case study on the reliability assessment of the emergency safety barriers of the LPG plant in Algeria based on the proposed methodology is provided and carried out to illustrate its effectiveness and feasibility. The results demonstrated the ability of intuitionistic fuzzy sets aggregation procedure and subjective safety analysis to provide highly reliable results and evaluate the reliability of emergency safety barriers.

Consequently, it only allows you to estimate the occurrence probability of accident scenarios.

Batteries run the sensor nodes those are used in WSN. The battery is impossible to charge or repair, so the most valuable resource for wireless sensor networks is power. Over the years, several strategies have been invented and used to preserve this precious WSN resource. One of the most successful approach for this purpose has turned out to be clustering. The aim of this paper is to suggest an effective technique for choosing cluster heads in WSNs to increase the lifetime of the network. To accomplish this task, Grey Wolf Optimizer (GWO) technique has been used. The general GWO was updated in this paper to meet the particular purpose of cluster head selection in WSNs. In this article, we have considered eleven attributes in the fitness function for the proposed algorithm. The simulation is carried out under different conditions.

Different types of brain tumors are known, so the choice of treatment depends directly on the type of tumor. The classification of brain tumors is very important as a complex and challenging problem in the field of image processing. Today, deep learning methods are used to classify brain tumors. In addition to being able to detect and automatically classify all types of brain tumors, these methods significantly reduce the diagnosis time and increase accuracy. In this paper, a deep learning-based model is proposed to classify brain tumors into three classes: glioma, meningioma, and pituitary tumor. In the first phase, the pre-trained network ResNet50 is used to extract features from MRI images. In the second phase, by proposing two attention mechanisms (depth-separable convolution-based channel attention mechanism and an innovative multi-head-attention mechanism), the most effective spatial and channel features are extracted and integrated. Finally, the classification phase is performed. Evaluations on the Figshare dataset showed an accuracy of 99.32%, which performs better than existing models.
