Application and Comparison of Deep Learning Methods to Detect Night-Time Road Surface Conditions for Autonomous Vehicles

, 2022
Currently, road surface conditions ahead of autonomous vehicles are not well detected by the existing sensors on those autonomous vehicles. However, driving safety should be ensured for the weather-induced road conditions for day and night.

Development of Road Surface Detection Algorithm Using CycleGAN-Augmented Dataset

Sensors, 2021
Road surface detection is important for safely driving autonomous vehicles. This is because the knowledge of road surface conditions, in particular, dry, wet, and snowy surfaces, should be considered for driving control of autonomous vehicles.

The use of computational fluid dynamics to assess the hull resistance of concept autonomous underwater vehicles [PDF]

, 2007
Autonomous Underwater Vehicles (AUV’s) provide an important tool for collecting detailed scientific information from the oceans depths. The hull resistance of an AUV is an important factor in determining the powering requirements and range of the vehicle.

Design and implementation of autonomous surface vehicle

2018 19th IEEE Mediterranean Electrotechnical Conference (MELECON), 2018
This paper explores the design and implementation of an autonomous surface vehicle (ASV) at Qatar University which includes mechanical design, image processing, control and navigation, and power management. A PID controller is designed for the heading control and waypoint control of the ASV and both simulation and experimental results are presented.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
