    • Develop algorithms to determine the status of car drivers using built-in accelerometer and GBDT
    Authors: Thi Thu, Nguyen; Phuc Thinh, Doan; Anh-Ngoc Le;  Advisor: -;  Co-Author: - (2022)

    In this paper, we introduce a mobile application called CarSafe, in which data from the acceleration sensor integrated on smartphones is exploited to come up with an efficient classification algorithm. Two statuses, "Driving" or "Not driving," are monitored in the real-time manner. It enables automatic actions to help the driver safer. Also, from these data, our software can detect the crash situation. The software will then automatically send messages with the user's location to their emergency departments for timely assistance. The application will also issue the same alert if it detects a driver of a vehicle driving too long. The algorithm's quality is assessed through an average a...
    • Interpolated hybrid DBIM approach for enhanced imaging in ultrasound tomography
    Authors: Tran, Quang Huy; Khai Tuan, Nguyen; Phuc Thinh, Doan; Duc Tan, Tran;  Advisor: -;  Co-Author: - (2022)

    In ultrasound tomography (UT), Born iterative method (BIM) and distorted-Born iterative method (DBIM) based on Born approximation are considered efficacious. DBIM offers faster convergence compared to BIM; however, it is more susceptible to noise and vice versa. Combined or multi-model imaging is an indispensable trend of modern imaging to detect and accurately assess tissue states. The proposed method exploits the advantages, limiting the disadvantages and increasing the imaging speed of the merging of BIM and DBIM
