Abstract: The structure of bus network is very significant for bus system. To evaluate the performance of the structure of bus network, indicators basing on graph theory and complex network theory are proposed. Three forms of matrices comprising linestation matrix, weighted adjacency matrix and adjacency matrix under space P are used to represent the bus network. The paper proposes a shift powe...

Approximately one-fifth of Perth’s population is aged 60 or older. Projections suggest that this proportion will continue to increase as a result of the large number of children born after the World War II (1946– 1964). Access to and accessibility around train stations for the aging population is and will become a more important issue as the elderly population continues to grow. The aim of the ...

Buzz-net is a local network supported by a pair of unidirectional buses to which stations are connected via passive interfaces. The access protocol is a hybrid which combines random access and virtual token features. More precisely, the network operates in random access mode at light load and virtual token mode at heavy load. Because of the virtual token implementation, Buzz-net retains high ef...

The uniform-traac capacity of switchless, non-bus-oriented, ber-optic single-hop intercon-nections among N stations, each equipped with a small number of transmitters and receivers, can be as high as (log 2 N) concurrent transmissions on a single wavelength with round-robin scheduling in a time-slotted system. However, their capacity with the Slotted ALOHA access scheme does not increase with N...

Observed engineering challenges of developing water quality monitoring networks are presented in this paper and appropriate solution approaches are proposed. Water quality monitoring stations are important tools in the area of environmental water science that are used to collect measurement values. Because of missing plug-and-play support in prevalent field bus systems and lack of semantic info...
