    Real Time Sentiment Analysis of Twitter Data
    (Library Information Services, CUI Lahore, 2022) Maryam Ahmed; SP19-BCS-015; Hasan Jamal
    This project does live sentiment analysis of Twitter data to classify it into positive, negative, or neutral sentiments. It focuses on extracting tweets in real-time using Twitter APIs, pre-processing it, and then applying sentiment analysis to it. This data will help us apprehend people's perspectives and opinions about diverse topics. Different machine learning models such as, SVM, Naïve Bayes, Logistic Regression and Random Forest are trained on a relevant dataset to achieve the best possible accuracy. The results of the project are reported for the Random Forest classifier since it resulted in the highest accuracy on testing data. After prediction of the sentiments of real-time tweets the results have been visualized in the form of different types of charts. Nowadays, when everything is on social media, it is crucial to detect and limit negative exposure to keep the social media sites safe to use and positive for all age groups. Twitter is one of the most influential platforms today where a lot of data is generated daily making it the most appropriate platform for our project.

    Synthesis Study Of Fe2O3/CS Nanocomposite And Its
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2021) Maryam Ahmed; SP20-RPH-032; Dr. Akber Ali; LHR TP 7716
    Nano study and Nano system have risen in importance above the last three periods, with applications in practically every scientific field, including biological, chemical, computer, electrical/optical sensing, electronics, and mechanic. The capacity to create nanodevices of diverse materials with lower sizes and varied forms, for example globular particles, Nano organisms as well as effectively built difficult designs of these structures [1]. Faraday investigated a figure of ways to manufacture gold saturations in a historic lecture; nevertheless, the Turkevich (1951) approach is the most often used. The Lee-Meisel (1982) approach, on the other hand, is commonly used for the creation of silver particles. It is a variant of the Turk approach, however unlike the Turkevich method, it is very good in accumulating metallic particles in a wide range of sizes [2].
