Integrating IoT and Novel Approaches to Enhance Electromagnetic Image Quality using Modern Anisotropic Diffusion and Speckle Noise Reduction Techniques

Electromagnetic imaging is becoming more important in many sectors, and this requires high-quality pictures for reliable analysis. This study makes use of the complementary relationship between IoT and current image processing methods to improve the quality of electromagnetic images. The research presents a new framework for connecting Internet of Things sensors to imaging equipment, allowing for instantaneous input and adjustment. At the same time, the suggested system makes use of sophisticated anisotropic diffusion algorithms to bring out key details and hide noise in electromagnetic pictures. In addition, a cutting-edge technique for reducing speckle noise is used to combat this persistent issue in electromagnetic imaging. The effectiveness of the suggested system was determined via a comparison to standard imaging techniques. There was a noticeable improvement in visual sharpness, contrast, and overall clarity without any loss of information, as shown by the results. Incorporating IoT sensors also facilitated faster calibration and real-time modifications, which opened up new possibilities for use in contexts with a high degree of variation. In fields where electromagnetic imaging plays a crucial role, such as medicine, remote sensing, and aerospace, the ramifications of this study are far-reaching. Our research demonstrates how the Internet of Things (IoT) and cutting-edge image processing have the potential to dramatically improve the functionality and versatility of electromagnetic imaging systems

High Speed Wireless Data Transmission Using Li-Fi for Android Mobile

Nowadays the audio video data transmission between two android phones takes time. This paper gives the design of system full-duplex wireless visible light communication (VLC) system based on Light fidelity (Li-Fi) which transmit data bidirectional simultaneously by using LED as transmitter and Si PIN (Hamamatsu S6968) photodiode as receiver between two android mobile. This system develops a prototype to demonstrate a bidirectional wireless communication system based on Android Mobile. In this system, two android mobiles phones can transmit local data stored in the memory of mobile to each other anyone mobile either act as a transmitter or receiver. The system consists of two parts mainly one is hardware and other software. The hardware design is based on the USB port integrated to Android Mobile. The development of software utilizes the protocol of AOA (Android Open Accessory) which is a new feature in Android 3.1 or more advanced version  by connecting external USB bridge which  allowing data transmission between Android devices over USB interfaces. Combing with a USB port on one board, it can achieve up to 3Mbps bit rates error free, which is mainly limited to the USB bridge circuit between two mobiles for data transmission such as text, audio and video. This paper also shows the experimental results and the relationship between system transmission eye diagram and bit rate. &nbsp

Automatic Ventilator Respirator for Patient with Variable BPM & Oximeter

The article describes the development of a cost effective, automated portable respirator that delivers breaths using a conventional ambu bag that eliminates the need of a human operator. It’s a portable mechanical ventilator that delivers breathing using a standard ambu bag. The paper shows that this design can be utilized for mass casualty cases such as covid-19 in recent scenario and other poor resource environments. This system firstly measures the oxygen levels of the patient and accordingly the user can set a particular value through breath per length and breath per minute nodes, these values are pre-set for a certain amount of oxygen levels and should be accordingly set while using hence to take the maximum benefit of the model. In addition, the system includes a pressure sensor to measure the overall pressure within the system so as to provide more vital information regarding a patient’s health. After all, values are set as per standard requirements for machine according to which the motor within the system gets activated through microcontroller making ambu bag press, and providing the necessary air to the patient

Raspberry-Pi base Advanced Safety Helmet for Mine Workers

Mining is world's most dangerous professions. In some nations, underground miners lack safety and social protection, be left to fend for themselves if injured. Additionally, there are adverse societal repercussions, including displacement and loss of livelihood. Mining has the greatest fatality rate of any industry. The most workplace fatalities poisoning, and electrocution. There are various case studies regarding underground mines; for example, a recent case study in China indicated that underground mining is the world's deadliest business. disasters, we developed a more advanced communication technology that must work in tandem with an intelligent sensing and warning system. The most critical component in every business is safety. are paramount in the mining business. To avoid mishaps, the mining sector takes critical safeguards

Treatment of gray water using anaerobic biofilms created on synthetic and natural fibers

Gray water treatment and reuse is an immediate option to counter the upcoming water shortages in various parts of world, especially urban areas. Anaerobic treatment of gray water in houses is an alternative low cost, low energy and low sludge generating option that can meet this challenge. Typical problems of fluctuating VFA, low pH and sludge washout at low loading rates with gray water feedstock was overcome in two chambered anaerobic biofilm reactors using natural fibers as the biofilm support. The long term performance of using natural fiber based biofilms at moderate and low organic loading rates (OLR) have been examined. Biofilms raised on natural fibers (coir, ridge-gourd) were similar to that of synthetic media (PVC, polyethylene) at lower OLR when operated in pulse fed mode without effluent recirculation and achieved 80-90% COD removal at HRT of 2 d showing a small variability during start-up. Confocal microscopy of the biofilms on natural fibers indicated thinner biofilms, dense cell architecture and low extra cellular polymeric substances (EPS) compared to synthetic supports and this is believed to be key factor in high performance at low OLR and low strength gray water. Natural fibers are thus shown to be an effective biofilm support that withstand fluctuating characteristic of domestic gray water. (C) 2013 The Institution of Chemical Engineers.
