  • Smart Mask using Arduino

      Authors: Sharmila ; Vanshika Sharma, Sristhi Chaudhar, Abhinav Rawal, Abhay Tyagi
      Abstract: COVID 19, mask becomes the integral part of our life. It plays the role of personal protective equipment against the virus. As per guidelines of WHO (World Health Organization) wearing appropriate mask and maintenance of social distance are the key factors to prevent the spread of virus. The prolonged use of surgical and N95 mask by people and healthcare professionals during COVID 19 which leads to adverse effects such as headaches, skin breakdown, rashes, difficult breathing etc., When the same mask is used for longer duration, it attracts pollutants, buildup of virus load and humidity which poses ill health. The proposed smart mask provides a solution for negating the effects of disposable/ reusable masks. The sensors fixed in the smart mask detectseveral parameters like humidity, temperatureand an alarm when the social distance is not maintained appropriately.

  • Enhancement of Proton Density Weighted Magnetic Resonance Images using
           Singular Value Decomposition in Wavelet Domain

    • Free pre-print version: Loading...

      Authors: K Kannan
      Abstract: Image enhancement techniques for low contrast medical images using Singular Value Decomposition (SVD) in Discrete Wavelet Transform domain (SVD-DWT) are proposed in the literature. However, shift sensitivity, poor directionality and a lack of phase information are the primary drawbacks of the discrete wavelet transform. This work introduces a novel method of image enhancement (SVD-SWT) using SVD in Stationary Wavelet Transform (SWT) to improve the contrast of Proton Density weighted Magnetic Resonance Images (PD weighted MRI) while preserving the brightness. The low frequency sub bands of PD weighted MRI and the low frequency sub bands of General Histogram Equalized PD weighted MRI are used in the proposed method as a weighted sum of singular value matrices to enhance the contrast of PD weighted MRI. The proposed method is compared with several histogram equalisation methods and improvement techniques employing Singular Value Decomposition and Discrete Wavelet Transform (SVD-DWT). Discrete Entropy (DE), Average Brightness (AB), Pixel Distance (PD), and Standard Deviation (SD) all showed that the proposed method is the best.

  • Audio Signal and Video Signal plotted w.r.to each other on a graph paper
           using X-Y Plotter and further Audio signal Listen at Tape Recorder and
           Video Signal Display at Color TV Monitor

    • Free pre-print version: Loading...

      Authors: Ganesh Adhikar; Anil Kumar Yadav
      Abstract: The article presents a concept of designing a Plotter circuit that becomes capable to plot two signals (Audio signal as well as Video signal) with respect to each other at a time on the single graph paper. Here two signals are; one is the audio signal from singer (Mr. Udit Narayan) song (Papa kehte hey) and another Video signal of CAR shape created using c-programming at computer Graphics, these two signals are plotted w.r.to each other on a single graph paper at the same time using the concept of X-Y Plotter; and further system is designed such that there becomes provision to Listen Audio signal at Tape Recorder and provision to display Video signal at color TV monitor. The basic concept behind this design process includes creating Audio signal at input and also creating Video signal of CAR shape at Computer Graphics. The Audio signal as well as Video signal so created at input are further plotted w.r.to each other on a single graph paper using the concept of X- Y Plotter and further facilitate with provision to listen audio signal at Tape Recorder and Display video signal at color TV. The basic purposes and assumptions regarding the design and development of this system as well as a description of its operation have been presented.
