This study investigated the effect of assimilated meteorological fields on simulated PM2.5 concentrations in the Korean Peninsula. Two different CMAQ simulations were conducted using base WRF run (BASE) and grid-nudged WRF run (GNG) which included a simple data assimilation method for the time period of April, 2009. The simulated PM2.5 and PM10 concentrations were compared with corresponding observations...
Free space and on-road obstacle detection is one of the key functions for the implementation of the vision-based intelligent vehicle and robot navigation system. Stereo vision-based algorithm for this task is more realistic and precious compared with radar or lidar-based algorithms. In addition, accurate estimation results can indicate the current and approaching conditions in the complex traffic...
In recent years, many electronic/mechanical systems have acquired mobility due to rapid technological advances and market demands. Mobile robots are a typical example. When a robot moves around in an uncontrolled environment such as a building corridor, safety of the robot and humans around is of great importance. Although ultrasonic range finders have been popularly employed so as to sense obstacles...
When a mobile robot is employed in an unstructured space, safety during its motion should be considered first. In particular, if the robot shares a workspace with humans, detecting humans in front of the navigating robot is of great importance in order to avoid collision. Although low-cost sensors based on ultrasound or infrared are widely used to avoid the robot's collision, they have limitations...
