In these days, there is a paradigm shift from internal-combustion-engine vehicles to electric vehicles.Most electric vehicles developed include batteries mounted at the bottom, near the rear wheels.Hence, the robust design of underbody parts against the impact of external bodies or random stone chipping needs to be made.In this study, the mathemati

This paper proposes the design of a single radiator monopulse antenna with a substrate integrated waveguide (SIW) multi-mode feeding system to reduce the aperture size and simplify the feeding structure.The proposed antenna can effectively reduce the overall system size by using a single patch radiator, compared to conventional systems that require

In the era of big data, Internet-based geospatial information services such as various LBS apps are deployed everywhere, followed EYE BALM by an increasing number of queries against the massive spatial data.As a result, the traditional relational spatial database (e.g., PostgreSQL with PostGIS and Oracle Spatial) cannot adapt well to the needs of l

Recent years have witnessed rapid developments on computer vision, however, there are still challenges in detecting tiny objects in a large-scale background.The tiny objects knowledge become sparse and weak due to their tiny size, which makes the tiny objects difficult to be detected with the common approaches.In this paper, a new network named Spe
