(BRAC University, 2017-07)To practice solving programming problems from online automated judge is very essential for competitive programmers since this helps develop critical thinking required for solving programming challenges in various programming ... -
Non-clinical Covid19 diagnosis on CT-scan, Chest X-ray, and respiratory patterns using deep-learning and signal processing
(Brac University, 2023-01)Despite various preventative measures and therapies, the COVID-19 pandemic has exposed a number of weaknesses and vulnerabilities in global health systems, particularly in low and middle-income countries that may have ... -
Non-local gravitational interactions and the black hole information paradox
(Brac University, 2019-12)This thesis looks into Non-local gravitational interactions that hawking radiated quanta’s from Black holes might possess. We shall first explain Hawking’s original calculation in [1], and how such a process would lead to ... -
Nonperturbative phenomena in field theory and gravity, and use of Borel summation to capture nonperturbative information
(BRAC University, 2017-12)This thesis addresses non-perturbative phenomena and techniques to analyze nonperturbative problems. First, we discuss the simplest non-perturbative example in quantum gravity: blackholes, and how they non-perturbatively ... -
A novel approach for detecting and recognizing mathematical symbols
(BRAC University, 2016)Extraction and recognition of mathematical characters and equations for documented images is important for many applications, artificially intelligent systems in particular to store or analyze mathematical data. It is vital ... -
A novel approach for digital image watermarking
(BRAC University, 2016-08)In this paper, a novel adaptive digital image watermarking model based on modified Fuzzy C-means clustering is proposed. For watermark embedding process, we used Discrete Wavelet Transform (DWT). A segmentation technique ... -
A novel approach for predicting the evolutionary origin of acquisition of foreign genes in bacteria: application of codon usage analyses
(BRAC University, 2009)Lysogenic bacteriophages, are considered as a major player for the introduction of foreign genes into bacterial strains. At the time of introduction foreign genes do not fit well into the translation system of the recipient ... -
Novel approach to detect hate speech and profanity on online platforms
(Brac University, 2021-09)Hate speech is becoming more prominent and dominant in the virtual world, with the popularity of social media increasing day by day. People nowadays have various online platforms where they can express their hatred and ... -
A novel approach to forecast traffic congestion using CMTF and machine learning
(BRAC University, 2018-04)Traffic congestion severely affects many cities around the world causing various problems like fuel wastage, increased stress levels, delayed deliveries and monetary losses. Therefore, it is urgent to make an accurate ... -
