The only way to prevent blindness from eye problems is by early detection and prompt treatment. Although colour fundus photography (CFP) is useful for fundus inspection, there is a need for computer-assisted automated diagnosis tools due to the similarities between the early symptoms of many eye disorders. The suggested approach uses cutting-edge deep learning model to categorize images into several disease categories by learning distinguishing features from the input images. The high-resolution fundus photos from individuals with diabetic retinopathy (DR), glaucoma, cataract, and healthy eyes make up most of the dataset used for this research. The experimental findings show that the suggested system achieve 97% accuracy with modified efficientNetB3 model and surpasses current approaches for categorizing eye diseases. This approach may help doctors diagnose and treat eye conditions earlier, leading to better patient outcomes.

Cardiovascular disease (CVD) results in malfunctioning of the heart and also the related blood vessels and regularly primes to death or corporal paralysis. Initial and automated discovery of CVD is crucial for saving many of the common humanoid lives. While several Investigations have been carried out to achieve this goal, and there is still room for development in terms of performance and reliability. This new work provides one more step in this area, since it utilizes two reliable ML algorithms, 'multi-layer perceptron (MLP)' and 'K-nearest neighbour (K-NN)'to detect CVD using publicly available data from the University of engineering California Irvine source. The models' concerts are enhanced optimally and by eradicating the possible outliers and common existing attributes with values that are treated as null. They performed general Experimental and effective findings show that the MLP model outperforms the KNN model in terms of reporting accuracy (82.47%) and area below the curve (86.41%). As a result, the proposed MLP model is recommended for automated CVD identification. Furthermore, this approach may be used to identify new illnesses, and the suggested model's routine can be tested against other standard datasets. © 2024 IEEE.

What the human visual system can perceive is strongly limited by the capacity of our working memory and attention. Such limitations result in the human observer’s inability to perceive large-scale changes in a stimulus, a phenomenon known as change blindness. In this paper, we started with the premise that this phenomenon can be exploited in video coding, especially HDR-video compression where the bitrate is high. We designed an HDR-video encoding approach that relies on spatially and temporally varying quantization parameters within the framework of HEVC video encoding. In the absence of a reliable change blindness prediction model, to extract compression candidate regions (CCR) we used an existing saliency prediction algorithm. We explored different configurations and carried out a subjective study to test our hypothesis. While our methodology did not lead to significantly superior performance in terms of the ratio between perceived quality and bitrate, we were able to determine potential flaws in our methodology, such as the employed saliency model for CCR prediction (chosen for computational efficiency, but eventually not sufficiently accurate), as well as a very strong subjective bias due to observers priming themselves early on in the experiment about the type of artifacts they should look for, thus creating a scenario with little ecological validity.

This paper proposes a new encoder-decoder frame-work based on Convolutional Neural Networks (CNN) for feature extraction and Long Short-Term Memory (LSTM) networks for image caption generation. Image captioning, the process of generating descriptive textual content for images, has diverse applications, including accessibility tools for the visually impaired, virtual assistants, social media automation, and satellite imagery analysis in critical domains like defense and disaster management. The proposed model will leverage the power of CNNs for extracting high-level image features and LSTMs for generating semantically coherent captions. Rigorously evaluated on the Flickr8k dataset, the model achieved competitive BLEU scores, showing its efficacy in generating accurate and meaningful descriptions. The methodology integrates advanced preprocessing techniques and efficient training strategies, ensuring robustness and scalability. This re-search focuses on the need to use state-of-the-art machine learning techniques in the solving of real challenges, and some of the potential routes to improving image captioning systems are suggested to include multilingual capabilities and integration with larger datasets. Contributions include a clear explanation of the encoder-decoder approach, detailed metrics for evaluation, and insights into correcting limitations including dataset size and complex scene representation. This work is a step toward further progress in automated image-to-text systems, integrating precision, relevance, and adaptability.

Solar Photovoltaic (SPV) based standalone water pumping systems especially without batteries are becoming more popular due to its feature. The SPV system output power is always varying and depends on solar irradiance which cannot be regulated and unpredictable. Hence, standalone water pumping system without integrating any storage device is a challenging task. Further, an appropriate control method must be required to regulate speed of the motor according to power available from SPV system. In this paper an induction motor is considered and developed a novel energy management algorithm to operate battery less standalone water pumping system powered by SPV system. To obtain higher efficiency and utilization, maximum power point tracking (MPPT) device is also developed. A single stage water pumping system is developed by integrating control of inverter to MPPT algorithm. The dc-link voltage is also regulated along with speed of the induction motor by proposed control methodology. A multi motor-pump sets are considered for the application of agriculture. In order to get an effective operation, deloading concept is also included in the proposed control method. Various results are demonstrated by performing OPAL-RT modules based hardware-in the-loop. © 2024 IEEE.

Trust is an important factor that contributes to citizens' willingness to continuance use of e-gov services. However, there is a lack of prior investigation about trust and continuance use of e-gov services in Pakistan - a developing country. We propose a model to investigate citizens' trust and e-gov services' continuous use intention to fill this research gap. Our study collected data from an online survey of 558 Pakistani citizens. Using partial least squares analysis, we found that disposition to trust positively correlates with both internet and government trust. Moreover, citizen satisfaction, trust, perceived usefulness, confirmation, and perceived risk all have significant impacts on the continuous use intention of e-gov services. This research extends and validates the Expectation-Confirmation Model by exploring key factors that influence e-gov continuance use intention. As such, our study offers valuable insights for policymakers and practitioners involved in e-gov service delivery in developing countries like Pakistan. The paper also discusses our findings' implications and identifies future research directions.

Relevant data technology advancements have led to a massive growth in classifications. Deep learning systems, however, need help handling such a massive volume of data. This work aims to use the Evaluation of different classification algorithms for big data, Comparison of accuracy, precision, recall, and F1 score among various algorithms, and Identification of algorithms suitable for handling large-scale datasets and conventional deep learning to analyze a large amount of data. Classifiers allowed researchers to examine how various random sampling strategies affected the model's performance. Two methods of feature selection were employed in the tests. The Bayesian Network likewise employs a single deep learning classifier. By lowering the dimensionality of the data, this study seeks to maximize model performance. A recording dataset larger than 60 GB was made less dimensional to conduct the trials. The findings demonstrate that, when employing both sampled and non-sample data, overall performance varies between 78% accuracy and 82% accuracy, a minor variation in performance while utilizing both sampled and non-sample (all the data) datasets. The random subset approach and the Bayesian network classifier were employed in the trials, and the overall findings show that the variety experiment had the best performance out of all the combinations of experiments. Test Cradle Experimentation: Variation length, delay variation, and packet loss are used to assess the predicted scheme's efficiency.

Recently, it has been shown that most automatic speaker verification systems (ASV) are vulnerable to various spoofing attacks. These spoofing attacks can be divided into three major categories: those deriving from text to speech (TTS), voice conversion (VC), and replay spoofing attacks. In the last couple of years, many researchers have proposed many algorithms to detect these spoofing attacks in ASV systems and have made considerable improvements. This paper presents a novel bonafide and spoofed audio detection approach using machine learning and deep learning classifier models with resampling and data augmentation techniques. This paper uses seven machine learning classifier models with different entropy features and three deep learning classifier models with various acoustic features. The performance of these classifier models is analyzed using metrics like precision, recall, accuracy, equal error rate, loss, and confusion metrics. State-of-the-art authors used equal error rate as their performance measure metric; our primary focus is on equal error rate in this paper. And we observed that in our proposed methodology, the deep learning classifier models showed considerable performance improvement. The training phase shows approximate 100% accuracy with a loss of 0.0090 and an equal error rate of 0.06%. In the evaluation phase, it offers approximate 98% accuracy with a loss of 0.0906 and an equal error rate of 1.72%.

For the past few years, there has been an increase in road accidents all over the world. The most common crucial reason is drowsiness. The presented work deals with this problem to reduce the number of accidents while keeping the methodologies simple and intact with the usage of computer vision applications like blink rate, eye closure, yawning. Detection of the driver's drowsiness is done by a single-camera attached behind the steering wheel and to identify yawning and for alerting the driver, a buzzer is triggered when the eyes are closed and also when the count of yawning is greater than the specific rate. The system will also work even the driver is wearing glasses and it can be implemented with the comfort of a pocket phone. © Published under licence by IOP Publishing Ltd.
