High-precision control problems for carrier-based UAVs are challenging due to the requirements safety, high-performance operation and uncertain ocean environments. To address such problems, this paper proposes a direct lift landing method that can ensure safe of using intelligent optimization performance indicators dynamic optimal allocation methods. The (DLC) scheme is adopted improve operabil...

Distribution Line Communications technology allows the usage of electrical power supply networks for communications purposes and, today, also broadband communication services. The main idea behind DLC is the reduction in operational costs and expenditure for realization of new telecommunications networks. Using electrical supply networks for telecommunications has also been known since the begi...

DLC coatings are of enormous interest for biotribological applications due to their biocompatibility, auto-lubricious, and non-stick properties. The most demanding implant is the hip joint. Alternative materials to metal alloys are being increasingly investigated aiming low wear debris volume, in any case innocuous wear particles. Silicon nitride (Si3N4) ceramics are light, tough, mechanical re...

Diamond and diamondlike carbon (DLC) films exhibit a wide range of sometimes contradictory tribological behavior. Experimentally, isolating the influences of factors such as film structure, testing conditions, and environmental effects has proven difficult. In this work, molecular dynamics simulations were used to examine the effects of film structure, passivation, adhesion, tribochemistry, and...

Osteoarthritis-oriented synovial fluid (OASF), i.e., that typical of a patient with osteoarthritis, has different physical and biological characteristics than bovine serum (BS), a lubricant widely used in biotribological investigations. Micro-dimpled and diamond-like carbon- (DLC) coated surfaces are key emerging interfaces for orthopedic implants. In this study, tribological performances of di...

Every year, billions of dollars are invested in research and development for space applications, including new systems, technologies, materials. DLC (Diamond-Like Carbon) is a promising material use these but its faces technological barrier, since it severely etched by atomic oxygen ozone. In this study, SiOx-DLC thin films were deposited as top layer diamond-like carbon (DLC) on Ti-6Al-4V subs...

The biological response of human microvascular endothelial cells (HMEC-1) seeded on Si-DLC films and on control surfaces was evaluated in terms of initial cell enhancement, growth, and cytotoxicity. The microstructure of the films was characterised by Raman spectroscopy and X-ray photoelectron spectroscopy. The effect of changes in microstructure, surface energy, surface electronic state, and e...
