International Journal of Online and Biomedical Engineering (iJOE), Год журнала: 2023, Номер 19(04), С. 155 - 173

Опубликована: Апрель 3, 2023

Watermarking is widely used in multimedia preservation and communication, which comprises, therefore not limited to, data security validation. Security, readability, imperceptibility, resilience are some of the key advantages this technology. However, there still certain issues that need to be addressed, such as ability withstand a variety assaults without substantially affecting quality value embedded data. Based on its operational domain, watermarking technology may divided into two groups: spatial frequency watermarking. An index mapping-based approach for copyright protection multi-media color videos presented paper. We offer hybrid discrete wavelet transform cosine (DCT) algorithm digital video watermark. Peak signal noise ratio (PSNR), similarity structure measure (SSIM), have been analyze distortion produced by It suggested proposed method provides greater imperceptibility conjunction with each other human visual system it offers higher robustness against different attacks.

Reliable Fuzzy-Based Multi-Path Routing Protocol Based on Whale Optimization Algorithm to Improve QOS in 5G Networks for IOMT Applications

International Journal of Interactive Mobile Technologies (iJIM), Год журнала: 2023, Номер 17(06), С. 139 - 155

Опубликована: Март 21, 2023

The Internet of Medical Things (IoMT) faces stiff competition from the 5th Generation (5G) communication standard, which includes attributes like short and long transmission ranges, Device to (D2D) connectivity, low latency, high node density. To function in linked ecosystem, IoMT based on 5G is anticipated have a diversity energy mobility. It currently difficult create an routing system that maximizes efficiency, lowers increases network lifespan. "Quality Services (QoS)" 5G-based improved by Reliable Fuzzy-based Multi-path shown this study. Whale Optimization Algorithm (WOA) enhances protocol performance. residual energy-based Cluster Head (CH) selection strategy rotates CH location among nodes with greater levels than others. method chooses following set CHs for suitable applications considering initial energy, ideal value CHs. According simulation results, our suggested technique QoS comparison current approaches.

The subject of sentiment analysis through social media sites has witnessed significant development due to the increasing reliance people on in advertising and marketing, especially after Corona pandemic. There is no doubt that prevalence Arabic language makes it considered one most important languages all over world. Through human comments, can know things if they are positive or negative. But fact, comments many, takes work evaluate place product a detailed reading each comment. Therefore, this study applied deep learning approaches issue provide final results could be utilized differentiate between dataset. Sentiment Analysis was used gave percentage for negative commentary. This eight methods techniques using Fast Text as embedding, except Ara BERT. These transformer (AraBERT), RNN (Long short-term memory (LSTM), Bidirectional long-short term (BI-LSTM), Gated recurrent units (GRUs), (BI-GRU)), CNN (like ALEXNET, proposed CNN), ensemble model (CNN with BI-GRU). Hotel Reviews Dataset test models. paper obtained following results. In BERT model, accuracy 96.442%. CNN, like Alex Net 93.78%. suggested 94.43%. LSTM 95%. BI-LSTM 95.11%. GRU 95.07%. BI-GRU 95.02%. 94.52% Ensemble been proposed. Consequently, AraBERT outperformed other terms accuracy. Because already trained some Wikipedia entries.
