The University of South Australia is a public university in the Australian state of South Australia. It was formed in 1991 with the merger of the South Australian Institute of Technology and Colleges of Advanced Education. The legislation to establish and name the new University of South Australia was introduced in 1990 by the Hon Mike Rann MP, Minister of Employment and Further Education. With more than 33,000 students, the university is South Australia's largest; more than 10,000 students are international, with almost half studying in Adelaide and the remainder offshore.Under the University's Act, its original mission was "to preserve, extend and disseminate knowledge through teaching, research, scholarship and consultancy, and to provide educational programs that will enhance the diverse cultural life of the wider community." In 2013 a new Vision, Mission and Values statement was released as part of a new strategic direction, "Crossing the Horizon".UniSA was the youngest Australian institution to be named in the top 50 of 2013 The Times Higher Education's Top 100 global universities aged under 50.The University is a founding member of the Australian Technology Network of universities. It has two Adelaide city centre campuses, two Adelaide metropolitan campuses, and two South Australian regional campuses. Wikipedia.

A multiple access slotted wireless communication system comprising a plurality of terminals and a multi-access receiver is described. The multi-access receiver can decode multiple transmissions in each slot of a frame from terminals in its field of view. Each terminal has an active state for transmitting and an inactive state. After receiving acknowledgement of a successful transmission by the terminal, the terminal enters the inactive state for at least a transmission delay time. This may be the remaining time that the terminal is in the field of view of the multi-access receiver. This may be achieved by the terminal using a probability of transmission to determine whether or not to transmit in the next frame. The terminal may also be configured to select the slot in a frame, and this may be based upon information such as which slots were acknowledged. The receiver may use compression to transmit acknowledgement messages.

A communication system is disclosed. In an embodiment, the communication system includes a user node for receiving data from a remote application program, the data including message data for communication to a central application program operatively associated with the remote application program; plurality of geographically distributed gateway nodes; one or more access nodes for receiving the message data from the user node via a first communications interface, and communicating the message data via a second communications interface to one or more of the plurality of geographically distributed gateway nodes; and a hub for communicating with the one or more of the plurality of geographically distributed gateway nodes to receive the message data for communication to the central application.

A least squares estimator of carrier phase and amplitude in a receiver in a communication system using a phase shift keying modulation scheme that uses both known pilot symbols and unknown data symbols is described. That is, the method exploits knowledge of pilot symbols in addition to the unknown data symbols to estimate carrier phase and amplitude. Further, an efficient recursion based estimation method is described that only requires O(L. log L) arithmetic operations where L is the number of received signals. This method uses the M-Ary rounded phase offsets to sort the data symbols and this sorted order is used to recursively calculate candidate values in an optimisation process. Simulation results show that the estimation methods Using data and pilot symbols outperform estimation methods using only data symbols (ie non-coherent detection methods). Further, the system can be used for systems using multiple M-ary phase shift keying digital modulation schemes.

A weed seed devitalization arrangement for use with a. combine harvester, attached to the combine harvester, towed behind, or standalone. The weed seed devitalization arrangement receives weed seeds entrained in a. portion of the air and material previously discharged from a combine harvester or other crop/lawn cutung apparatus. The weed seed devitalization arrangement includes a rotonstator arrangement including but not necessarily excluding other elements, one or more stationary substantially circular array of weed seed impact members, the members being arranged so as to impact weed seeds being provided into the substantially circular array; and one or more rotatable substantially circular array of weed seed impact members, the rotatable array movable with respect to a stationary substantially circular array of weed seed impact members, the impact members of the rotatable substantially circular array arranged to impact weed seeds being directed through the rotatable substantially circular array. Another element may be a driven rotating clement at or near the central portion of the rotor/stator arrangement for receiving the portion of air and material discharged from the combine harvester entrained with weed seeds and for providing a flow of air and entrained material including weed seed into the arrays of the arrangement.
