    Graeme Reade Anthony Ellis (universally known as ‘Bill') was a pioneer in the area of low-frequency radio observations. By exploiting Hobart's geomagnetic latitude and the lack of background radio noise there, he was able to make major discoveries at these low frequencies (principally in the frequency range 1–10 MHz). Among the questions he pursued were the propagation/dispersion/reflection of radio waves in the ionosphere and the detection of radio emissions from the Sun, the galactic disk and Jupiter. He built innovative radio receivers and de-dispersers to gain information about the radio sources, for example about the Sun via aurorae and about the influence of Io on the Jovian emissions. It is thanks to Ellis' practical research investigations and clever experimental methods that radio astronomy at the University of Tasmania is today firmly established and internationally recognized

    Hydraulic Model Study of the Blue River Dam Power Plant, Penstock, and Outlet Works

    The Stone and Webster Engineering Corporation (S&W) contracted with St. Anthony Falls Hydraulic Laboratory (SAFHL) to construct and test a physical hydraulic model of a modified stilling basin for the Blue River Dam Power Plant Project outlet works. This project was designed by Stone and Webster for the Eugene Water and Electric Board. Modification to the stilling basin was necessary to accommodate changes in the design of the outlet structure necessitated by the installation of hydroelectric power generating turbines. The basin is presently owned and operated as a flood control structure by the U.S. Army Corps of Engineers (COE). The facility is operated according to COE procedures within the general constraints of a reservoir water surface level of maximum 1357 ft MSL and minimum 1180 ft MSL, and between the minimum and maximum flows of 50 cis to 8400 cfs, respectively. Flow exiting the reservoir is controlled through gates located at the upstream end of a 2000 it long 18.5 diameter conduit. The downstream end of the conduit concludes in an open channel outfall into the existing stilling basin. The design scheme for the hydro facility involved modifying the outlet works to incorporate a multiple bay gated outlet structure and a bifurcation leading to the powerhouse. Modifications included pressurization of the penstock and outlet works necessitated by the combined usage of the flow conduit for both hydropower and flood discharge. The objective of the study was to perform comparative testing of the existing outlet works stilling basin and the proposed design. In this effort, the study evolved into five distinct phases of testing. The test results are summarized according to phases with the reason for and objectives of the next phase outlined in the conclusion of each existing phase. A summary of the various phases is as follows:Stone & Webster Engineering Corporation; Eugene Water and Electric BoardVoigt, Richard L.; Erickson, Benjamin; Ellis, Christopher R.. (1994).

    Wind Energy Feasibility and Energy Education Project Lower Sioux Community

    The results of wind speed and direction measurements carried out in the Lower Sioux Community during the twelve~month period from November 1, 1995, to October 31, 1996, are reported. The measurement were performed using six wind anemometers and six wind direction vanes installed at four sites in the community. The data presented include the monthly averages of the semi~hour1y wind speeds and of their cubes, monthly wind roses, the probability distributions of the wind speeds and the parameters of Wei bull distributions fitted to them, turbulence intensity data, and total energy roses for each month. The data are presented so as to streamline a comparison with wind energy data at other area sites where comparable records may be available. Possible sites and methodology for such a comparison and errors which may arise in a potential extrapolation of the twelve-month record to longer time periods are discussed.Office of the Environment Lower Sioux CommunityFarell, Cesar; Ellis, Christopher R..
