Air detrainment in high-speed chute flows
(2002)Hydraulic Measurements and Experimental Methods 2002Air added to high-speed chute flows is known to reduce the potential of cavitation damage at the chute floor. Therefore hydraulic model experiments using advanced fiber optical instrumentation were conducted to investigate two-phase flows with regard to air detrainment. Two different set-ups for air addition to water flow were studied, namely: (1) Pre-aerated discharge supply, and (2) Chute aerator. Differences between the two set-ups are ...Conference Paper -

Pier and abutment scour - New laboratory data
(2002)Proceedings of First International Conference on Scour of FoundationsThe purpose of this paper is threefold: (1) Presentation of a scour installation used over the past 6 years; (2) Summary of results pertaining to the Shields entrainment criterion that was expanded for bridge pier and bridge abutment; and (3) Discussion of new results. Based on a long term investigation of scour, the experimental method was improved to result presently in an installation that might be of general interest. Accordingly, ...Conference Paper -

Characterizing the statistical properties of mutual information in MIMO channels: insights into diversity-multiplexing tradeoff
(2002)Conference Record of the Thirty-Sixth Asilomar Conference on Signals, Systems and Computers, 2002We consider Gaussian multiple-input multiple-output (MIMO) fading channels assuming that the channel is unknown at the transmitter and perfectly known at the receiver. Taking into account spatial fading correlation both at the transmitter and the receiver, a tight closed-form lower-bounds is provided for ergodic capacity and an accurate closed-form approximations of the variance of mutual information are derived over such channels. Based ...Conference Paper -

Hydraulic design of stepped spillways for RCC dams
(2002)Proceedings of the 2002 International Conference on Roller Compacted Concrete Dam Construction in Middle East (RCC 2002)Few definite design guidelines for stepped spillways are available to date. To fill in this gap, experimental model studies on the characteristic two-phase skimming flow down a stepped chute were conducted at the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) of the Swiss Federal Institute of Technology (ETH), Zurich. The paper focuses on significant findings of the research program and the development of design guidance to ...Conference Paper
