Harmful marine spills, such as algae blooms and oil damage ecosystems threaten public health tremendously. Hence, an effective spill coverage removal strategy will play a significant role in environmental protection. In recent years, low-cost water surface robots have emerged solution, with their efficacy verified at small scale. However, practical limitations connectivity, scalability, sensing...

Facebook groups host user-created communities on Facebook’s global platform, and their administrative structure consists of members, volunteer moderators, governance mechanisms developed by the platform itself. This study presents viewpoints volunteers who moderate that are dedicated to political discussion. It sheds light how they enact day-to-day moderation work, from administration group mem...

<p style='text-indent:20px;'>This article deals with the dynamic stability of a flexible cable attached at its top end to cart and load mass bottom end. The model is governed by system one partial differential equation coupled two ordinary equations. Assuming that time-dependent delay occurs in boundary, main concern this paper stabilize dynamics as well dynamical terms related mass. To d...

The ability to control boundary behaviors is critical for the subdivision surface to become a useful representation in computer aided geometric design. Previous methods achieve boundary control by extending the boundary vertices of the control mesh, or by applying different subdivision rules to the boundary edges and vertices. This paper presents an open uniform quadratic subdivision scheme der...
