    Our main purpose of this project is to help the people . Basically our project is health oriented and random people would be benefited using this web service named Blood Bank. Before implementing this idea we went through various types of research to check if there were any sort of web service available similar to our idea and we found some web service but we want to implement it in a different pattern so that general people can use it without facing any problem. Suppose, if there is any emergency and anyone needs a necessary group of blood then they can get the necessary information regarding the blood donor and according to their requirement’s they can contact each other through this web service. In the frontend part of our web service we are using html, css, javascript. In the backend part we are using Django. For the documentation and testing we are using Swagger. We are using sqlite for our database and for API’s we are implementing in Restful API. Through the building process of this website, we have to undergo different types of research to make our system even more helpful and easier to access for the general people. We faced several difficulties when we started to implement this because some things were not possible as we intended then tried different ways to solve those problems following comparatively easy procedures. And finally, we are able to make this web service as we desire.

    Reconstructing Better Audio by Using Spetial Microphone
    (North South University, 2019-08-31) Md Mantasarul Elahi; Dr. Mohammad Ashrafuzzaman Khan; 1512518042
    This article describes the design and implementation of a program that is capable of taking audio from multiple sources and using two filters, it will create the best possible version of the audio that is possible. Firstly, after taking in audio from multiple audio recording sources, it will firstly go through ’Unwanted Noise Reduction Filter’ and its product will be a noise reduced output. After going through the first filter, the audio files will be filtered once again using ‘Voice Enhancement Filter’ and will produce an enhanced output. Lastly, all the audio files will be combined using ‘Audio Merging Process’ to produce the final output of the best possible version of the audio that has been recorded
