Introduction: This publication is the product of research developed within the research lines of the Smart Sensing, Signal Processing, and Applications (3SPA) research group throughout 2018, which supports the work of a doctor’s degree at VNU University of Engineering & Technology, Vietnam.
Problem: The limitations of diagnostic ultrasound techniques using echo information has motivated the study of new imaging models in order to create additional quantitative ultrasound information in multi-model imaging devices. A promising solution is to use image sound contrast because it is capable of detecting changes in diseased tissue structures. Ultrasound tomography shows speed-of-sound changes in the propagation medium of sound waves. This technique is primarily used for im... |
Compared to oceanic waterway transportation, inland waterway transportation has not received the deserved attention on technological support. In the development of Boat Safe, we offer a mean of inland-waterway-oriented navigation, crash detection and post-crash emergency aid through smartphone application, which can be easily accessed at any time. We also propose the use of complementary filter on compass, gyroscope data for heading estimation with miniscule uncertainties. |
