Abstract

Anomaly detection in motor bearings is a critical task for preventing downtime and ensuring efficient operation. This paper proposes a novel approach for anomaly detection using Fast Fourier Transform (FFT) and Long Short-Term Memory (LSTM)-Autoencoder (AE). A data processing approach based on FFT was developed to pre-process the raw sensor data. This helped to reduce noise and improve the Signal-to-Noise Ratio (SNR). Additionally, an anomaly detection model based on LSTM-Autoencoder was developed and trained on the pre-processed data. The proposed approach was able to detect anomalies at a low threshold and achieved a high accuracy score.

Abstract

Navigation of empty parking slots has been proposed to solve the major problem of traffic congestion at parking places, such as malls and theatres. In other words, it can also reduce time consumption and costs. When there is no information about free parking slots, drivers face the issue of spending time to find a suitable parking spot. In multi-story buildings or malls, it is even more difficult to find an available parking. To solve this issue, the navigation of empty parking slots is used. In many parking areas, there is only an automated entrance to enter the vehicle into the parking area, but there is no software that can display live video to consumers to show whether there is an available space. Additionally, there is no website or application that can show live footage of the parking area, indicating whether it is empty or occupied. In this research live information is displayed before drivers enter the parking area. With the help of the display and website, drivers can save a significant amount of time finding an empty parking slot to park their vehicle. The system is based on camera sensors and software, where image processing is used to process the image.

Abstract

Finding missing people is a time-critical and labor-intensive task and the longer it takes to locate the person, the lower the likelihood of a successful outcome. To address this challenge, an integrated and centralized database of missing persons using Aadhar card details was developed. The approach incorporates facial recognition technology, specifically the deep face algorithm, which has shown high accuracy in identifying individuals. While facial recognition has been in use for several years, recent advancements have made it easier to identify individuals accurately. By leveraging Artificial Intelligence (AI) powered facial recognition technology, officials can enhance and streamline the process of finding, tracking, and retrieving missing persons. The system matches facial features with the data stored in Aadhar cards, providing a reliable means of identification. This research presents a system that centralizes data, improving the efficiency of locating missing individuals. By utilizing facial recognition and centralizing data, the system offers an efficient approach to find missing people. The integration of technology and data allows quick and more accurate identification, increasing the chances of locating missing persons promptly.

Abstract

Current digital radar systems have limitations at higher frequencies, and a new approach is needed to be able to operate in different environments and at higher frequencies. Photonics offers a solution to these limitations. It has UltraWide Bandwidth (UWB) and high precision, which allows for the flexible generation of highly consistent Radio Frequencies (RF) signals and the accurate direct digitization of signals without down-conversion. This research proposes a novel Wavelength-Division Multiplexing (WDM)-based photonics link for a radar demonstrator. The proposed system uses a single pulsed laser as a source to design a transceiver for high-speed data transmission and reception. The system can generate tunable radar signals and their echoes, avoiding the up/down conversion of radio frequency and ensuring both high resolution and simulation-based operation. The proposed system has the potential to revolutionize radar technology by enabling high resolution that can operate at higher frequencies. The system is also scalable and can be easily adapted to different radar applications.

Abstract

Facial expressions convey a lot of information about the emotional state of a person and even a small change in it can help to detect changes in an individual's mood. Researchers have conducted numerous studies in the fields of machine learning and computer vision, training ML models to detect various human emotions or moods based on captured facial features. In this research, a system was proposed which is capable of identifying the user's emotions and moods and suggesting a list of appropriate songs to improve their mood. Incorporating mood detection offers significant benefits to customers' mental health and personal satisfaction. The objective of this system is to capture the user's image, detect their mood and create a music player system that recommends music based on the user's real-time mood, utilizing a web camera and deep learning algorithms
