Microwave technology plays a central role in current wireless communications, standing among them mobile communication and local area networks (LANs). The microwave range shows relevant advantages with respect to other frequencies open-air transmission, such as low absorption losses energy consumption, it is additionally the natural working frequency superconducting quantum technologies. Entang...

Abstract Thin copper films with thickness ∼28 nm deposited on SiO 2 substrate the vacuum electron beam evaporation method and treated by UV-ozone are studied. It was found that a treatment of film causes rapid formation thin ∼3-4 oxide film. XPS analysis showed CuO predominates in this The formed effectively protects against following oxidation. presented is simpler cheaper approach compared to...

The maximal rates that buses can discharge from bus stops are examined. Models were developed to estimate these capacities for curbside stops that are isolated from the effects of traffic signals. The estimates account for key features of the stops, including their target service levels assigned to them by a transit agency. Among other things, the models predict that adding bus berths to a stop...

Rising landfill costs have forced solid waste managers to consider waste streamreduction alternativessuch as household recycling. Explaining the factors which motivate households to recycle is important to regions where households must bear a large portion of the recycling cost because unit-based garbage disposal fees and curbside recycling are not feasible options. Empirical results indicate t...
