Organizations normally focus on delivering the product that could earn maximum profit for the client. They do not focus on time, cost and quality. So the resultant product is of poor quality, over budget, over time, poorly satisfies the client’s requirements, and is high in cost. In this research paper, we will use lean concepts in software project management. It will not only remove all the waste in project management but also improve the project’s quality, time, and cost. We will also compare the project management concept with the lean project management concept and how combining these two will give us a perfect idea to increase software quality, reduce time, and deliver faster delivery. The only drawback is that current standards of software project management are not mature enough to adopt lean management to its extent.

The software requirements specification (SRS) can become a problem & barrier to the successful completion of a project, this can become an obstacle to the successful delivery of a project through the software requirements specification (SRS). In some cases, this results in not addressing real needs. The SRS dataset can include duplicate data or disputed content which cause high costs and wastage of the time and the general effectiveness of the project will be reduced. Latest advancements in machine learning have led to active endeavors to formulate automated approaches for generating seamless software requirements specification [6]. We thus apply transformer models, such as BERT and RobERTa in this study, for classification. We examine multiclass text classification with RoBERTa and classification tasks involving the prediction of type, priority, and severity of user-specified requirements. Along with that, we compare its performance to other natural language processing (NLP) models like LSTM and BiLSTM. Our experiments on the DOORS dataset demonstrate higher accuracy using RoBERTa compared to existing approaches. Assessment parameters included accuracy, F1 score, recall, and precision.

This research presents a blockchain-based framework for secure and efficient medical image sharing, prioritizing data integrity and privacy. The framework involves two key phases: image compression with feature extraction and image encryption with storage on the InterPlanetary File System (IPFS). Medical images are compressed using the JPEG algorithm to reduce file size while maintaining diagnostic value. A deep neural network-based subject sensitive hashing (SSH) algorithm ensures feature map integrity by extracting consistent features from both original and compressed images. Encrypted images, along with SSH-generated hashes, are securely stored in the IPFS server. The encryption key and hash sequence are used for secure image retrieval, with smart contracts validating access requests based on the hash sequence. This multi-stage feature extraction approach demonstrates robust image integrity, security, and privacy, as verified by experimental results. Achieving an average correctness rate of 98% across multiple datasets, the framework significantly enhances healthcare data management by addressing the challenges of secure, scalable, and private medical image sharing. This research contributes to the development of more efficient, reliable, and privacy-conscious solutions for medical image handling in healthcare systems. © 2025 The Author(s).

With the rapid development of the internet of things and smart cities, the demand for effective spectrum collaboration has grown *** maps play a crucial role in understanding the spatial radio environment, which is essential for wireless applications such as cell planning and radio resource management. However, generating radio maps is a resource-intensive task, as the construction process is complex and the distribution process consumes substantial bandwidth. This article proposes a method that combines semantic communication (SemCom) and generative artificial intelligence (GAI) to optimize the construction and distribution processes of radio maps. By incorporating SemCom, our method transmits only key semantic information during the distribution process, significantly reducing bandwidth usage while ensuring accurate and efficient information transfer. While the diverse generative capabilities of GAI introduce some instability, which could be a limitation in radio map construction, this article achieves precise content decoding through prompts based on multi-modal semantic information, enabling accurate construction and restoration of radio maps. By utilizing SemCom and GAI technologies, the cost of applications of radio maps can be significantly reduced, which is beneficial for stimulating the pace of intelligence evolution in future mobile networks. © 1986-2012 IEEE.

In six ICDCM conferences, the value of future DC systems, and DC homes for reducing losses in our electrical systems was discussed indicating the need for a DC-based future. DC outputs from renewable sources contribute to reducing CO2 emissions and lowering electrical energy consumption. In modern white goods, internal circuits are based on DC power rails derived from AC mains followed by a rectifier. Powering AC households from renewable requires maximum power point tracking based on battery chargers and inverters. End-to-end efficiency is related to the number of individual converters inside an equipment. Here we describe a low-frequency supercapacitor-assisted converter system coupled with an "inverter-driven"refrigerator converted to DC operation by eliminating the rectifiers. With this modification, whiteware becomes more tolerant of variable DC sources, allowing continuous operation without battery buffers in solar or wind energy systems. A modified 230 V, 50 Hz refrigerator for DC operation was connected with a supercapacitor module rated at 110 V DC, allowing it to run directly from a renewable source and eliminating the need for battery buffering. This is another supercapacitor-assisted technique based on the relatively new supercapacitor-assisted loss management concept and it eliminates the requirement for electromagnetic compatibility filtering. © 2025 IEEE.

Robots are getting deployed at home and in industries, becoming an integral part of our daily lives. Sophisticated mechanisms are required to make the joints of the robots compact and simple. In this paper, we have developed a flexure joint for the fingers of the robotic hand. The flexure joint is arranged in series to make a three-DOF underactuated finger. Five fingers are arranged to make a robotic hand. Castigliano’s theorem is used to develop the deformation related to the applied loads, using the equation the flexure mechanism was designed. Pseudo-rigid model is developed to determine the stiffness of the flexure mechanism. A virtual model of the flexure mechanism is developed in a CAD environment. Finite Element (FE) simulation is conducted to the different loading conditions to evaluate the performance of the flexure mechanism. It was seen that the flexure mechanism is flexible about the rotational axis and stiff about the other axes. The stiffness model developed using the pseudo-rigid model has a good correlation with the FE simulation model. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Road accidents are a primary global concern for public safety, with India having a very high death toll. This study presents an intelligent machine learning approach to predict the severity of road accidents, contributing to the development of more effective and preventive measures. We utilized a comprehensive dataset of road accidents in India, employing advanced machine learning algorithms, including Histogram-based Gradient Boosting (HGB), Random Forest (RF), Support Vector Machines (SVM), and K-Nearest Neighbors (KNN). Our methodology involved extensive data pre-processing, feature engineering, and model optimization. The Random Forest algorithm demonstrated superior performance, achieving an accuracy of 94.7% and an F1-score of 0.947. This research provides a robust predictive model and information on the key factors influencing the accident's severity. The novelty of our approach lies in the comprehensive feature engineering tailored to the Indian context and the application of ensemble learning techniques to capture complex, nonlinear relationships in accident data. The findings of this study have significant implications for policymakers, urban planners, and law enforcement agencies in their efforts to improve road safety. © 2025 IEEE.

A strong foundation for a project is the first step to measuring or estimating the success parameters of a project. Requirement engineers gather and elicit the requirements of the project in detail after the feasibility study. A project’s success can be measured/estimated if and only if the initially collected requirements are clear, unambiguous, and well-understood. Similarly, ambiguous or not understandable requirements can lead to failure or closure of the project in disastrous form. An initial step in requirement elicitation is usually gathering requirements in natural language. This study analyzes different tools, techniques, and approaches in different research articles used for detecting ambiguities in requirements in the natural language. We identified 33 research articles, published during 2012-24 through a Systematic Literature Review. For automated ambiguities detection in requirements engineering, we identified 17 tools & techniques and 12 NLP approaches. We analyzed the better approach for cross-domain ambiguity detection. SGNS (Skipgram Negative Sampling) variant of Word2Vec for the cross-domain ambiguity detection in the review of the study, resulted to be the most efficient technique implemented with the usage view and easily scalable for multiple requirements and domains.

This paper presents a comparative study of key metrics for OCR engines in Bangla language processing. PyTesseract (a Python wrapper for Tesseract OCR) and EasyOCR were benchmarked on a novel dataset, "Bangla-CrossHair,"created for testing OCR engines. This dataset combines samples from "Bangla Text Detection and Recognition,""Bangla Handwritten Characters,"and "Bangla Handwritten Words"datasets and includes diverse image types, such as blurred, clear, torn, and tilted. Results show EasyOCR outperforms PyTesseract in several scenarios, while PyTesseract consistently demonstrated faster processing. Since many OCR engines provide pre-trained capabilities, traditional metrics like training and validation accuracy are challenging to measure for some models, including PyTesseract. Instead, Character Level Accuracy, Word Level Accuracy, Levenshtein Distance, Character Error Rate, Word Error Rate, Precision, Recall, F1-Score, and Inference time were measured for an unbiased evaluation. © 2025 IEEE.

Reconfigurable intelligent surfaces (RISs) have recently been employed to facilitate communication and improve performance by reflecting signals through configuring phase shifts toward the intended destination. This article examines the physical layer security of an underlay cognitive radio network aided by an RIS and in the presence of multiple eavesdroppers. The research is conducted under practical conditions, encompassing RIS hardware constraints and cascaded fading channels. An optimization problem is proposed with the objective of maximizing the secrecy rate of secondary users by optimizing the reflection angles of the RIS and the transmission power of the secondary user transmitter. A deep reinforcement learning method, specifically the soft actor-critic, is presented as a solution. The results section demonstrates the effect of altering the number of RIS elements on security. We also analyze the impact of hardware limitations and cascade levels on the secrecy rate. The effect of varying the number of eavesdroppers and the maximum permissible transmission power are also examined.
