American Sign Language (ASL) recognition aims to recognize hand gestures, and it is a crucial solution to communicating between the deaf community and hearing people. However, existing sign language recognition algorithms still have some drawbacks, such as difficulty recognizing hand movements and low recognition accuracy for most sign language recognition. A Modified Convolutional Neural Network (MCNN) deep residual 101 classifier-based American Sign Language identification system has been developed to address this problem. There are three main parts presents in the method. The first part is pre-processing the images to remove the noise, enhance the contrast of the picture, adjust the contrast level and smoothen the picture using various filters. The second part is the segmentation, and it’s used to partition the image using a modified canny edge detection method by removing all weak edges present in the image. Finally, classification will be done using the Modified CNN deep residual 101 classifiers. By classifying the image, the American Sign Language is accurately identified. This process is conducted through images. The outcome shows that the suggested approach has a 0.97% accuracy and a 0.05% False Positive Rate. Other CNN architectures such as resNet 50 and resNet 18 reached 0.90% and 0.80% accuracy, respectively, which is lower than our proposed method. In addition, the resNet 101 classifier effectively recognizes the difficult hand gestures through the image data. It obtains high recognition accuracy for 36 signs is 0 to 9 numbers and a to z alphabets from American Sign Language. © The Author(s), under exclusive licence to Springer science+Business Media, LLC, part of Springer Nature 2025.

Background: Software vulnerabilities are flaws in application source code that can be exploited to cause harm, hence companies must devise strategies to manage ***: We want to understand how software vulnerabilities are managed in a big IT (Information Technology) service and consulting company like NTT ***: We conducted a focus group involving six software professionals working at NTT data and analyzed the gathered data through a thematic analysis ***: We found that application security standards are defined based on the needs of the clients (i.e., companies that commissioned NTT data the software to be developed) and the projects' nature (i.e., the development of greenfield projects vs. maintenance of existing ones). Also, to detect software vulnerabilities, SAST (Static Application Security Testing) tools are mainly used;among these, SonarLint and SonarQube appear to be the de-facto standards for NTT data. Finally, not all software vulnerabilities are fixed;for example, the presence of some software vulnerabilities is tolerated by the clients, who take on the responsibility of not removing these ***: It seems that developers and NTT data clients are not averse to securing their code. NTT data follows the application security standards established with their clients. To detect software vulnerabilities, SonarLint and SonarQube appear to be the de-facto standards, so explaining to some extent the increasing attention on these tools by the software engineering research community. © 2023 IEEE.

Nail denting or crumbling may result from nail psoriasis. A nail condition known as psoriatic onychodystrophy or psoriatic nails. Psoriasis sufferers frequently experience it;reported occurrences range from 10% to 78%. Psoriatic nails are more common in the elderly and in people with psoriatic arthritis. By examining the nails on a human hand, numerous illnesses can be found early in the diagnosing process. The nail color of an individual can help in the diagnosis of specific medical disorders. In this case, the recommended method results in the decision-making process for sickness diagnosis. The system is fed by human nail art. The technique recognizes nail features unique to a given condition by analyzing images of nails. The suggested technique makes advantage of the various distinctive characteristics of human nails to detect illness by changing the colour of the nails. The first training set data, which is derived from an image of a patient's nails with a particular ailment, is handled by the Weka tool. To get the desired results, the feature discoveries of the picture are compared to the training dataset. The distortion of the nail unit is known as nail disease. Nail units have their own disease class due to their own indications, symptoms, causes, and consequences, which may or may not be related to other medical disorders. Nail problems are still difficult and ambiguous to identify. A novel machine learning method for recognising and classifying nail problems from photographs is presented in this study. This framework combines CNN models with data mining techniques to extract characteristics. This research was also contrasted with certain other province algorithms (Support vector, ANN, K - nearest neighbors, and RF) evaluated on datasets and showed positive results. The accuracy numbers show how well the model can distinguish nail conditions. This ground-breaking discovery lays the groundwork for precise diagnosis in dermatology, medical image processing, an

PALCT: vehicle-to-vehicle communication based on pseudonym assignment and encryption scheme using delay minimisation cover tree algorithm

International Journal of Vehicle Information and Communication Systems 2025年第2期10卷 132-147页

作者： Tandon, Righa Gupta, P.K.

Vehicle-to-vehicle communication is one of the new paradigms of networking, which should be secure, fast, and efficient. In this paper, we propose a framework that implements the pseudonym-based authentication scheme in which communication among vehicles is encrypted by using a matrix array symmetric key (MASK), digital signature algorithm (DSA), and intelligent water drop (IWD). The proposed security scheme also ensures the handling of many security attacks like key-guessing, non-repudiation, replay, and modification. In the proposed scheme, to preserve the identity of the vehicle, we have provided the different pseudonyms for each vehicle in the network that ensure secure communication among vehicles. Furthermore, the proposed delay minimisation cover tree algorithm ensures the issue of timed delay during vehicle-to-vehicle communication. In this algorithm, we have used Dijkstra’s algorithm for finding the optimal shortest path during vehicular communication. The results obtained show that the proposed scheme is effective and efficient, as it reduces the time delay by 4% for 140 vehicle nodes and 28.4% for 1000 vehicle nodes.

GPT is a large language model (LLM) derived from natural language processing that can generate a human-like text using machine learning. However, these models raise questions about authenticity and reliability of material, particularly in fields such as journalism, social media, and academia, despite their usefulness for automating text-based tasks. Detecting machine-generated text is thus an important difficulty in ensuring content integrity. This study investigates the use of huge language models as a technique for recognizing machine-generated material. The author proposes a comprehensive detection model by evaluating the language patterns, syntactic structures, and stylistic traits that separate AI-generated literature from human writing. In addition, this research investigate the possibilities of fine-tuning models designed expressly for text identification tasks and evaluate their performance using LLM - Detect AI Generated Text datasets. In digital ecosystems, LLMs are effective at detecting AI-generated text, providing a novel approach for content moderation, academic integrity checks, and synthetic media detection. An increasingly AI-powered future will require a model that can discriminate between human and machine-generated writing in real-time. According to experimental findings, the CNN architecture's design combined with the use of DistilBERT embeddings allows for the effective and efficient classification of AI generated text data, achieving an exceptional 98% accuracy rate. © 2024 IEEE.

Sarcasm, a sort of sentiment characterized by a disparity between the apparent and intended meanings of the text, is a key component of sentiment analysis, opinion extraction, and social media analytics. However, sarcasm detection in Bangla has not received sufficient research attention yet. Moreover, there hasn't been a significant amount of study done comparing traditional and contextual word embeddings for the Bengali language. This study aims to address this gap by comparing traditional embedding by using the Bidirectional Gated Recurrent Unit - BiGRU model and contextual embedding by using Bidirectional Encoder Representations from Transformers - BERT for sarcasm detection in Bangla. The collection of the dataset of Bangla text was from social media platforms, containing labelled instances - whether it provides sarcasm or non-sarcasm. Pre-trained word embeddings i.e. GloVe and FastText are used as traditional embedding for this study. By using metrics like precision, recall and F1-score, the performances for both models have been obtained. When the two traditional word embedding approaches are compared, GloVe embedding with Bi-GRU has outperformed FastText embedding with a macro-averaged F1 score of 0.9395. On the other hand, contextual word embedding using BERT has outperformed both the traditional approaches having a better macro-averaged F1 score of 0.9572 and greater class-wise performance as compared with traditional embedding for both non-sarcastic (96%) and sarcastic (96%) text detection. In our findings, contextual word embedding i.e. BERT has performed better as compared with the two traditional word embeddings for this specific Bangla sarcasm detection binary classification task. © 2023 IEEE.

With the promotion of cloud medical diagnostic applications, the telemedicine system has become increasingly mature, which brings about much convenience to the people’s lives. Meanwhile, the diagnostic time was greatly reduced. Due to telemedicine system usually involves the sensitive information of users, the privacy issue is urgently to be solved. In order to solve the above problem, an attribute-based designated verifier proxy signature scheme, combined with message recovery, is proposed for the telemedicine system. A proxy delegation is designed to allow the proxy signer to obtain the same signing capacity as the original signer, the attribute-based fine-grained access control is also present to enable the valid verification of the signature and recovery of data. In addition, the scheme achieves unforgeability of signature and can resist the chosen message attack in Random Oracle Model. The comparisons of performance analysis demonstrates that the scheme is efficient in signing and verification phases. Therefore, it could be well appropriate for telemedicine system. © 2022, Taiwan Ubiquitous Information CO LTD. All rights reserved.

Virtual Reality (VR) technology is a computer simulation system that allows the creation and experience of virtual worlds. Because of its immersive, interactive, and realistic characteristics, VR is increasingly useful in educational contexts. However, due to the limitation of communication technology, problems such as high latency and vertigo of VR gradually appear in the teaching process, greatly affecting the learning experience of learners. 5G's technical advantages with high speed, low latency, and large capacity can provide the possibility for VR to better serve teaching practice activities. Thus, based on the unique advantages of 5G, this paper describes the virtual reality experiment (VRE) of the 5G service convergence course based on 5G+VR. Combined with our school's training plan for the communication major, this paper proposes the VRE teaching model. According to the results of the learning effect and learning process evaluation, the VRE teaching model can effectively improve students' enthusiasm and initiative in learning, thereby promoting the cultivation of communication professionals. © 2023 IEEE.
