(BRAC University, 4/4/2018) Maliha, Maisha; Tareque, Ahmed; Roy, Sourav Saha; Arif, Hossain
Diabetic Retinopathy (DR) is human eye disease among people with diabetics which causes damage to retina of eye and may eventually lead to complete blindness. Detection of diabetic retinopathy in early stage is essential to avoid complete blindness. Effective treatments for DR are available though it requires early diagnosis and the continuous monitoring of diabetic patients. Also many physical tests like visual acuity test, pupil dilation, and optical coherence tomography can be used to detect diabetic retinopathy but are time consuming. The objective of our thesis is to give decision about the presence of diabetic retinopathy by applying ensemble of machine learning classifying algorithms on features extracted from output of different retinal image. It will give us accuracy of which algorithm will be suitable and more accurate for prediction of the disease. Decision making for predicting the presence of diabetic retinopathy is performed using K-Nearest Neighbor, Random Forest, Support Vector Machine and Neural Networks.
Intelligent security system

Keeping our homes and office spaces safe and secure from intruders has always been a priority in our lives and like everything else, adding technology in this aspect can make our existing security measure better and more efficient. For our thesis project, we are aiming to create an intelligent security system that will incorporate Raspberry Pi (RPi), Camera Module and Android operating system to make a real-time, user friendly and reliable form of security and surveillance system. The RPi uses Haar Cascade algorithm to extract facial features in given images to detect faces. With a machine learning approach along with Eigen faces algorithm, the program is trained to recognize the features of a face from images already fed to the system. The RPi uses opencv application to compare the new image with the images already stored in the SD Card for cross-referencing purposes. The images for cross-referencing can be copied to the SD Card with a computer or can also be uploaded via the Android application. If the system finds that the image does not match any image in the directory it uploads that image to the server set up in the RPi given that internet connection is available. On the other hand, if it matches, the RPi does not do anything. Once uploaded, the image can be viewed from the Android Application. The app will offer the user multiple options on notifications, image receiving/storing and disabling/enabling the service. By using this system, the user will get real time alert when there's activity within a predetermined area, check whether it is an intrusion or not and store photos for further investigations if required.

Unraveling public relations’ facets at Forethought PR
(BRAC University, 2022-04) Maliha, Maisha; Saba, Anika
A public relation company has an ability to deal with that acts as an appraisal of the public’s attitude and finds an individual’s or an organization’s policies and procedures that are in the public’s interest. It is a structured and conducted program that necessitates action in order to gain the public’s understanding and consent. The public’s opinion of the firm is based on how it is depicted through marketing, public relations efforts, media, stakeholders, workers, trade unions, and consumer advocacy organizations. A PR company works for the company who wants to be connected with their consumers. This paper will provide a theoretical perspective, different aspects of public relations companies, and at the same time the learning experience of my internship journey. Every chapter has discussed different topics. Company history, internship journey, related theories etc.
