Abstract: This study investigates the failure of a blanking die used to produce busbar connecting element parts on a mechanical press. During operation, the tool broke early than expected life. due to cracks. forming at the die center. This failure resulted in reduced production of the product. The analysis revealed high stress concentrations at the center of the die. These areas aim to identify the causes of the failure by studying the design closely and using finite element analysis with ANSYS software. A 3D model of the press tool was created by using NX software. The stress distribution is more where the cracks appeared in the failed tool. Poor clearance and design in the die increased these stress peaks. Recommendations are for improve press tool by adding same changes in design to reduce stress concentration, and improving material selection or heat treatment to improve toughness and fatigue resistance. That steps improve tool life, lower failure frequency, and enhance the reliability of busbar component element

Abstract: Efficient management of critical hospital resources such as intensive care unit (ICU) beds, oxygen supply, and medical staff has become a major challenge, particularly during large-scale healthcare emergencies. Conventional hospital management systems are largely reactive and often fail to anticipate sudden surges in patient demand, resulting in delayed responses and resource shortages. This paper presents MediCast, an AI-driven hospital resource forecasting and decision support system designed to predict ICU bed occupancy and oxygen demand in advance while supporting optimized resource allocation. The proposed framework employs Long Short-Term Memory (LSTM) networks for time-series forecasting of ICU admissions and oxygen consumption trends, and XGBoost models for learning complex patterns from structured hospital data. Based on the predicted demand, an optimization layer assists in efficient allocation of beds and staff resources to reduce overload and improve preparedness. The system also provides an interactive dashboard for real-time visualization of predictions, alerts, and analytical insights, enabling hospital administrators to take proactive decisions. By integrating predictive analytics and optimization within a unified platform, MediCast enhances operational efficiency, minimizes critical resource shortages, and supports data-driven healthcare management in high-demand scenarios.

Abstract: Gamification is changing how online learning works. When we add points, badges, levels and progress tracking, students feel more interested and complete topics on time. In this paper, we show NextGenHire, a simple system that mixes gamified learning with job recommendation.In this system, a student first logs in and creates a profile with their skills. After that, the student watches learning content like web development or app development. When the learning part is over, the student gives tests. In the test, the gamification part starts where the student gets points and results based on quiz accuracy, time taken and activity. After tests, the system checks the student’s skill performance and compares it with job requirements. Using this method, the system recommends suitable jobs for the student. We also use basic data and simple comparison to check if gamification helps students to stay active and learn better. From this, we observed that students show better engagement after adding gamification.Overall, NextGenHire helps students learn and also suggests jobs based on their skills and performance, reducing the gap between learning and hiring.

Abstract: Communicating with Deaf or hard-of- hearing people can be difficult at times and the chal- lenges are great in multilingual countries such as India. This study describes current work on this but offers a proposal for an animated ISL (Indian Sign Language) translation system from Marathi text and/or speech – based on the fact that there are many more English- MSL (Marathi Sign Language) resources available and, therefore, a ’significant access gap’ when considering Deaf users within our target country. The majority of currently available translation systems have been based upon machine learning; however, due to insuffi- cient parallel corpora/annotated sign data resources for Marathi-MSL, this method will not work. The proposed system adopts as an alternative a ’rule based’ method- ology which will map the Marathi language & grammar structures onto ISL using linguistic ’rules’ and dictio- nary and will develop this through web application using React.jsTailwindCSSFlask for the front end of the web application, while allowing use of ’browser based’ storage thus ensuring a very lightweight deployment. Given that ISL requires ’gestures’, ’facial expressions’ and ’spatial syntax’, it is not possible to translate word for word; rather, the system will also consider some important Marathi grammatical elements, e.g. inflection; location/post position, verb forms, sentence structure and will therefore generate an ISL output that more accurately represents the original Marathi and promotes communication and accessibility for Deaf individuals.

Abstract: This project addresses the challenge of robust audio content identification in noisy environments by developing an ML-based audio fingerprinting system.To overcome this limi-tation, our methodology leverages a deep learning approach, using a Convolutional Neural Network to automatically extract a compact, noise-invariant fingerprint from audio spectrograms. The system involves a multi-stage process: a diverse dataset of clean audio is first augmented with various types of noise which has different signal to noise ratios. The trained model then generates a unique fingerprint for each audio track in a database. Finally, these fingerprints are stored using a fast and efficient hashing mechanism, enabling quick retrieval and identification. Our evaluation will demonstrate that this ML-based system significantly outperforms Existing methods in terms of accuracy and robustness, particularly at low SNRs, thereby providing a more reliable solution for applications such as music recognition, broadcast monitoring, and copyright enforcement.It further introduces spectrogram normalization and data-driven feature learning that minimize the impact of background dis-tortions. A contrastive-learning objective enforces the noisy and clean versions of the same audio to have similar embeddings. To facilitate fast retrieval, the system uses an approximate nearest-neighbor search mechanism optimized for large-scale databases. The approach’s low cost computational for fingerprint generation and matching is also demonstrated by experimental results. In general, the proposed approach allows for a scalable, high-performance framework suitable for real-time audio identifi-cation in adverse acoustic environments.This paper proposes a machine learning-based audio fingerprinting system for accurate audio identification in noisy conditions. A Convolutional Neural Network (CNN) is employed to learn noise-robust and compact audio fingerprints from audio spectrograms. Noise is added to clean audio examples with varying signal-to-noise ratio (SNR) values to enhance robustness. Contrastive learning is employed to guarantee that embeddings of noisy and clean audio examples are similar. The produced audio fingerprints are stored through a hashing function, and an approximate nearest neighbor search is employed for efficient retrieval. Experimental results show enhanced audio identification accuracy with low computational complexity in low SNR conditions. The proposed system is appropriate for scalable and real-time audio identification tasks

Abstract: Ball valves are popular in factories for controlling liquids and gases because they are easy to make, last a long time, and shut off flow well. But regular ball valves are not always great at controlling how much liquid or gas flows through, especially when they are only partly open. V-port ball valves were created to fix this problem. The V-shaped cut in the ball helps to control the flow better. This research looks at how a V-port ball valve works using computer simulations. A 3D model of the valve was made, and simulations were run with different opening amounts and flow rates. The research looked at things like how fast the liquid or gas moves, how much the pressure drops, how much turbulence there is, and the valve's flow rate. The results show that the V-port design does a much better job of controlling flow than regular ball valves. It makes the flow smoother and reduces the chance of bubbles forming. The results also show that computer simulations are helpful for making better valve designs. The simu

Abstract: Cryptocurrencies have rapidly grown into a pop- ular medium of digital exchange, offering speed, security, and borderless transactions. While these benefits have driven global adoption, the pseudony- mous and decentralized nature of cryptocurrencies also makes them highly vulnerable to misuse in ille- gal activities such as money laundering, terrorism financing, and fraud. Recent reports highlight bil- lions of dollars being laundered annually through cryptocurrency channels, often using techniques like mixers, peel chains, and cross-chain transfers. Traditional Anti-Money Laundering (AML) sys- tems, designed mainly for conventional banking transactions, struggle to handle the complexities of blockchain-based transactions. They often func- tion as black boxes, providing risk scores without clear reasoning, and they are reactive rather than proactive in detecting suspicious activities. To address these challenges, the proposed sys- tem CryptoTrack: A Data-Driven System for De- tecting Cryptocurrency Laundering. The system leverages advanced analytics to identify suspicious accounts and transactions, while integrating Ex- plainable Artificial Intelligence (XAI) to provide transparent justifications for every detection. Un- like existing systems that only flag activities, Cryp- toTrack enables users and compliance officers to understand the exact reasons why a transaction is considered risky, thereby increasing trust and re- ducing false positives. A visualization dashboard further supports users by providing intuitive in- sights into detected suspicious activity. The proposed framework bridges the gap be- tween opaque detection models and the practical requirement for interpretability in financial mon- itoring. By combining data-driven detection, ex- plainability, and transparency, CryptoTrack offers a more reliable and effective approach to combating financial crimes in the rapidly evolving landscape of cryptocurrency.

Abstract: The present investigation was carried out to evaluate the effect of different agricultural substrates on the quality production of oyster mushroom (Pleurotus sajor-caju #392). The study was conducted using four agricultural waste substrates, namely wheat straw, rice straw, sugarcane bagasse, and maize straw for mushroom cultivation. The experiment focused on spawn running, pinhead appearance, maturity, flush-wise yield, biological efficiency, and nutritional composition of cultivated mushrooms. Results revealed that wheat straw showed the fastest spawn running and pinhead formation with maximum total yield and biological efficiency. Wheat straw recorded 1360 g total yield and 136% biological efficiency, while sugarcane bagasse showed the lowest yield performance. Nutritional analysis indicated that sugarcane bagasse had the highest protein content (8.75%), whereas maize straw recorded maximum crude fat content (10%). Wheat straw exhibited superior fiber and ash content. The findings conclude that wheat straw is the most suitable substrate for commercial cultivation of Pleurotus sajor-caju, whereas sugarcane bagasse can be used for improving mushroom nutritional quality. This study highlights the importance of selecting appropriate substrates for achieving better mushroom production and quality.

Abstract: Endophytic fungi are ubiquitous microorganisms that asymptomatically colonize the internal tissues of plants, representing an untapped reservoir of novel, biologically active secondary metabolites. This study investigates the endophytic fungal diversity associated with two ethnobotanically critical medicinal plants: Withania somnifera (Ashwagandha) and Amomum subulatum (Badi Elaichi), and evaluates their biomedical potential against clinically significant human pathogens. Healthy leaves, stems, and roots were subjected to a stringent multi-step surface sterilization protocol and inoculated onto Potato Dextrose Agar (PDA). A total of fifteen (15) distinct fungal endophytes were isolated and taxonomically characterized via macroscopic and microscopic morphotyping. The predominant genera identified included Aspergillus, Fusarium, Alternaria, Curvularia, Penicillium, and Phoma. The cell-free secondary metabolites were extracted using organic solvents and screened for antibacterial efficacy against Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli, Salmonella typhi, and Micrococcus spp. using the agar well diffusion assay. The bioprospecting profile revealed significant inter-species variability. Notably, Aspergillus flavus derived from W. somnifera exhibited a profound, broad-spectrum zone of inhibition against both Gram-positive and Gram-negative cohorts, with optimal metabolic yield quantified at a 7-day incubation kinetics threshold. These insights underscore the therapeutic relevance of plant-associated fractions as sustainable alternatives to combat escalating multi-drug resistance (MDR) phenotypes.
