Abstract This study explores how impulse buying is influenced by consumer psychology and the strategies used by e-commerce platforms during flash sales. These sales, often driven by limited-time offers, discounts, and countdown timers plays a significant role in encouraging spontaneous purchases. The research is employed by both the primary and secondary data. Data analysis was conducted using various methods including analysis, graphical representation, and categorical interpretation. The interpretation highlights how factors like countdown timers, promotional alerts, and limited availability prompt impulsive behavior. The findings highlight how important it is to understand the psychological factors that influence online shoppers during flash sales. The study also suggests that online businesses should follow ethical marketing methods to help customers make more thoughtful and informed buying decisions. This research adds useful knowledge to the areas of consumer behavior, online shopping strategies.

 Abstract

The increasing demand for sustainable and energy-efficient solutions has driven the development of innovative systems that harness renewable energy sources. This project, titled "Solar-BasedRotatingSignBoard," aims to design and implement an ecofriendly, self-sustaining rotating sign board powered by solar energy. The system utilizes a 12V 10W solar panel, a 12V battery, a solar charge controller, 12V LED strips, a 10 RPM DC gear motor, motor clamps, and a welded metal frame. The sign board is designed to display digital banner prints on both sides, making it suitable for advertising, informational displays, or public announcements. The primary objective of this project is to create a cost-effective, low-maintenance, and energy-efficient rotating sign board that operates independently of the grid. The 12V 10W solar panel captures sunlight and converts it into electrical energy, which is stored in a 12V battery via a solar charge controller. The charge controller ensures optimal charging and prevents overcharging or deep discharging of the battery, thereby enhancing its lifespan. The stored energy powers the 10 RPM DC gear motor, which rotates the sign board, and the 12V LED strips, which illuminate the display for enhanced visibility during low-light conditions. The mechanical assembly consists of a welded metal frame that provides structural stability and supports the rotating mechanism. The DC gear motor is securely mounted using motor clamps, and the sign board is attached to the motor shaft. The rotation speed of 10 RPM ensures smooth and consistent movement, making the display visually appealing. The digital banner prints are affixed to both sides of the sign board, allowing for dual-sided visibility. The entire system is controlled by an on/off switch, and the components are assembled using screws, nuts, and bolts for easy maintenance and durability. This project demonstrates the integration of solar energy with electromechanical systems to create a sustainable and functional solution. The use of renewable energy reduces operational costs and minimizes the carbon footprint, making it an environmentally friendly alternative to conventional sign boards. The system is designed to be portable and can be deployed in various locations, including remote areas with limited access to electricity. In conclusion, the Solar-BasedRotatingSignBoard project showcases the potential of solar energy in powering innovative and practical applications. It highlights the importance of renewable energy in addressing modern challenges and provides a scalable model for future developments in sustainable technology. This project not only serves as an effective advertising tool but also contributes to the global transition toward clean energy solutions.

 Abstract

The integration of voice control technology in assistive devices is a significant advancement for enhancing the independence and quality of life for individuals with mobility impairments. This paper presents the design and implementation of a voice-controlled wheelchair utilizing the ESP (Espressif Systems) microcontroller platform. The system leverages voice recognition capabilities to allow users to operate the wheelchair with spoken commands, thereby reducing the need for physical interaction with traditional controls. The proposed solution employs the ESP32 microcontroller, known for its versatility and connectivity options, as the central processing unit for the voice control system. A voice recognition module is interfaced with the ESP32 to process and interpret voice commands, which are then translated into control signals for the wheelchair's movement and functionality. The design incorporates safety features such as obstacle detection and emergency stop functions to ensure reliable and secure operation. This voice-controlled wheelchair system aims to provide a more intuitive and accessible means of navigation for users, particularly those with severe physical disabilities. The paper discusses the technical implementation, including the hardware integration, software algorithms for voice recognition, and the communication protocols between the ESP32 and the wheelchair's motor control units. Additionally, user testing and performance evaluation are presented to assess the effectiveness and user experience of the system. The results demonstrate that the voice-controlled wheelchair offers a viable alternative to conventional joystick-based controls, with improved ease of use and greater autonomy for the user.

 Abstract

This paper presents a Python-based investment model for multi-asset portfolio management using dynamic data visualization. The model integrates a wide range of financial instruments--such as stocks, mutual funds, and cryptocurrencies--and leverages Modern Portfolio Theory (MPT) to identify optimal asset allocations based on historical performance, volatility, and correlation. With the use of Python libraries like Plotly, Seaborne, and Matplotlib, the system visualizes risk-return trade-offs, asset correlation heat-maps, and portfolio diversification structures. These visuals not only aid investor comprehension but also support better decision-making in asset selection and re-balancing. The study demonstrates how visualization-driven insights can significantly enhance portfolio optimization, reduce risk exposure, and improve return consistency

 Abstract

Driver fatigue is a major cause of road accidents worldwide. Studies suggest that drowsy driving contributes to nearly 20% of serious road crashes. This project proposes a preventive approach: an Anti-Sleep Safety Alarm using Arduino Uno. The device monitors eye movements using an infrared (IR) sensor and activates an alarm when signs of drowsiness are detected. With increased urbanization, long working hours, and vehicular congestion, it becomes imperative to provide technological assistance to drivers to avoid fatigue-related mishaps. The primary motivation behind this system is affordability, ease of use, and effectiveness. As compared to high-end systems based on EEG, camerabased image processing, or AI-based facial analysis, our solution leverages basic electronic components to deliver a robust mechanism. This research details the system design, implementation, testing, and potential for real-world deployment.

 Abstract

A fingerprint is impression made by the frictional ridges of the fingers on various surface such as porous, nonporous and semi porous. Being one of the useful and robust forensic evidence fingerprints have been widely recognized as the primary human identification tool in forensic investigation. Latent or invisible prints are commonly found at the scenes of crime and thus require the use of visualization methods. The currently available fingerprint visualization powdered methods are chemical with toxic and potential health hazards are. This study proposes a cheap and relatively fingerprint powder from drumstick skins. The findings revealed that drumstick skin powder is capable of visualizing latent fingerprint on porous, non-porous and semi porous surfaces. The latent fingerprints enhanced by drumstick skin powder showed better visualization. It is a non-toxic, safe and easily available powder.
