 Abstract

With the aid of Long Short-Term Memory (LSTM) networks, this project seeks to explore and introduce a deep learning approach to sentiment analysis of film reviews. The proposed model utilizes an LSTM structure with embedding and dropout layers following a text preprocessing pipeline involving tokenization, sequencing, and padding. The IMDB dataset, comprising out of 50,000 movie reviews, is employed to train the model. The model classifies reviews as either negative or positive with a 0.8999% accuracy. Binary cross-entropy loss and Adam optimizer are employed to train the LSTM model, and hyperparameters are tuned for improved performance. Experimental results indicate the performance of the proposed method in addressing sequential dependencies in text data and captures intricate emotion patterns. The study demonstrates how deep learning methods can be applied to sentiment analysis, offering.

 Abstract

This project focuses on the design, simulation, and intelligent control of a 6-axis robotic arm developed for automated pick-and-place operations integrated with object detection and artificial intelligence (AI) capabilities. The mechanical structure of the arm was precisely modelled using CATIA, allowing for detailed configuration of joints, links and degrees of freedom required for complex spatial movements. The robotic system was then simulated in MATLAB and Simulink, where kinematic models were constructed using Denavit-Hartenberg parameters for accurate forward and inverse kinematics. AI was integrated through the use of MATLAB's Machine Learning and Image Processing toolboxes, enabling the robotic arm to detect and classify objects using vision-based techniques. Object detection was enhanced using AI-driven image recognition algorithms, which allowed the system to identify object shape, colour and type with improved accuracy and adaptability. A PID control algorithm and trajectory planning ensured smooth, responsive motion for pick-and-place tasks. Additionally, the implementation of AI allowed the robot to learn from its environment and improve task efficiency over time, demonstrating adaptive decision-making capabilities. Simulation results confirmed the robotic arm's ability to autonomously detect, grasp and place objects in varying conditions with high reliability. This project illustrates the synergy of mechanical design, control systems and artificial intelligence in creating smart robotic solutions suited for modern industrial automation, warehousing, and smart manufacturing environments.

 Abstract

Efficient water distribution is crucial for sustainable water management, particularly in urban and agricultural settings. Artificial Intelligence (AI) is transforming water distribution systems by optimizing resource allocation, minimizing wastage, and improving efficiency. AI-powered models leverage machine learning (ML), predictive analytics, and real-time data processing to monitor water demand, detect leaks, and adjust supply dynamically. This paper explores the integration of AI in water distribution networks, focusing on smart sensors, IoT devices, and AI-driven algorithms for predictive maintenance and demand forecasting. AI enables automated control of pumping stations, pipeline monitoring, and pressure regulation, ensuring optimal water supply while reducing operational costs. Additionally, AI enhances water quality management by detecting contamination risks and facilitating prompt corrective actions. By implementing AI-based water distribution systems, municipalities and industries can achieve sustainable water management, reduce losses, and improve service reliability. The research highlights case studies and future prospects of AI-driven solutions in water conservation and smart city planning.

 Abstract

ABSTRACT Storytelling is a powerful tool that allows brands to connect with audiences on a deeper, more emotional level. In today's competitive market, where consumers are bombarded with advertisements and content, a compelling narrative helps a brand stand out. Rather than simply promoting products or services, successful brands craft stories that evoke emotions, inspire trust, and build lasting relationships with their audience. Whether it's a tale of perseverance, a mission-driven initiative, or a relatable human experience, storytelling transforms a brand into something memorable and meaningful. By using authentic voices, real-life scenarios, and engaging narratives, companies create connections that go beyond transactions--turning customers into loyal brand advocates. Storytelling has become the heart of modern marketing, allowing brands to forge deep emotional connections with their audiences. A well-crafted narrative goes beyond selling products--it builds a brand's identity, evokes emotions, and fosters loyalty. Brands like Nike inspire resilience with stories of athletes overcoming adversity, while air bnb promotes a sense of belonging through authentic guest experiences. By using relatable characters, conflict, and resolution, brands create narratives that resonate. Whether through social media, video campaigns, or user-generated content, compelling storytelling transforms a brand into an experience that customers remember and cherish Key word: Brand advocates.

 Abstract

The construction sector in India is rapidly expanding, contributing significantly to urban development--but also emerging as a major consumer of groundwater, a resource already under severe stress. This literature-based review explores the complex relationship between construction activities and groundwater depletion across India. While agriculture has long been considered the primary driver of groundwater extraction, recent studies indicate that construction practices--such as concrete curing, material mixing, and site preparation--consume substantial amounts of water, often sourced directly from local aquifers through unregulated borewells. Evidence from national standards (IS: 456-2000) and empirical studies suggests that water demand during construction can reach up to 27 kiloliters per square meter of built-up area. Urbanization and land use changes have further exacerbated recharge loss, with impervious surfaces reducing infiltration by nearly 30%. This review consolidates findings from government reports, journal articles, and policy analyses to underscore the urgent need for water-efficient construction technologies, regulatory frameworks, and sustainable site management. Recommendations include rainwater harvesting, groundwater impact assessments, water audits, and integration of green building norms. The study concludes that recognizing and addressing the construction sector's groundwater footprint is essential for ensuring long-term water security and sustainable urban development in India

 Abstract

The biometric authentication is improved over the recent last years to enhance the security. Face Recognition and AI based authentication are regular models to validate the human presence. The attackers can hack the above mentioned biometrics so that there is a need to protect the users data with other biometrics like Finger Veins . In this work, we are proposing that Finger Veins as they are presented under the skin so there is less chance to hack and also economically viable. The feature extraction and registration process is carried out by the deep learning techniques like Convolution neural networks (CNN).
