Abstract: Provided are a curcumin nanoparticle complex having a modified particle surface and a method for preparing same. A curcumin nanoparticle complex includes curcumin and phospholipids and has a particle size of less than 1000 nm. A first coating layer containing a cationic material and/or a second coating layer containing an anionic material can be further added.

Abstract: A road surface recognition method may include extracting first point cloud data in a front road surface region of a vehicle from point cloud data generated by LiDAR of the vehicle, generating a point cloud map by use of a local map and the first point cloud data, determining a predicted driving route of the vehicle based on motion-related data of the vehicle; and generating a road surface height profile of the predicted driving route based on the point cloud map and the predicted driving route.

Abstract: An apparatus and method for estimating a vehicle pitch relative to a road. The apparatus includes a wheel speed sensor part which obtains wheel speed data, an inertial measurement unit (IMU) sensor part which obtains IMU data, a preprocessing part which extracts a stop section and a moving section on the basis of the wheel speed data and the IMU data, and a slope estimation part which estimates a vehicle pitch in the stop section and a road slope in the moving section and estimates a vehicle pitch relative to a road on the basis of the vehicle pitch and the road slope.
