An improved model for predicting the efficiency of hydraulic propeller turbines
(2005-10-31)
Field performance testing of hydraulic turbines is undertaken to define the head-power-discharge relationship that identifies the peak operating point of the turbine. This relationship is essential for the efficient operation ...
On finite-state vector quantization for noisy channels
(2004-12-31)
Finite-state vector quantization (FSVQ) over a noisy channel is studied. A major drawback of a finite-state decoder is its inability to track the encoder in the presence of channel noise. In order to overcome this problem, ...
Genetic elucidation of host use by individual sympatric bronzed cowbirds (Molothrus aeneus) and brown-headed cowbirds (M-ater)
(2006-09-30)
Species of avian brood parasites that use one or several species of hosts are called host specialists and generalists, respectively. To determine host use of individual bronzed cowbirds, Molothrus aeneus (Wagler, 1829), ...
A queuing-theoretic and optimization-based model for radio resource management in IEEE 802.16 broadband wireless networks
(2006-11-30)
We present a queuing-theoretic and optimization-based model for radio resource management in IEEE 802.16-based multiservice broadband wireless access (BWA) networks considering both packet-level and connection-level ...
Consolidation modelling of soils under the test embankment at Chek Lap Kok International Airport in Hong Kong using a simplified finite element method
(2001-04-09)
This paper models consolidation of the foundation soils under a test embankment at the new Chek Lap Kok International Airport in Hong Kong. The modelling used a simplified finite element method and material parameters ...
TLM-based modal-extraction approach for the investigation of discontinuities in the rectangular waveguide and the NRD
(2002-10-31)
This paper describes the development of a rigorous transmission-line matrix-based modal-extraction approach to analyze discontinuities in guided-wave structures in general, with particular attention to the nonradiative ...
Analysis of NRD waveguide-based components and transitions using the TLM-based modal extraction approach
(2006-12-31)
This paper presents a full-wave modal analysis of several typical components based on a nonradiative dielectric (NRD) waveguide technology using the transmission line matrix (TLM)-based modal extraction approach (TMEA) for ...
Limit states and reliability-based design for a non-codified problem of aqueduct buoyancy
(2006-08-04)
Limit states design methods and engineering judgement have been used to assess buoyancy issues for remediation of the 85 year old Shoal Lake Aqueduct in Manitoba. The study demonstrates how these methods can be applied to ...
On the recovery of a function on a circular domain
(2002-10-31)
We consider the problem of estimating a function f (x, y) on the unit disk {(x, y): x(2) -l- y(2) less than or equal to 1}, given a discrete and noisy data recorded on a regular square grid. An estimate of f (x, y) based ...
Modified Cam-Clay modelling of temperature effects in clays
(2001-06-30)
The Cam-Clay model for isothermal mechanical behaviour of clays has been extended to take account of the effects of temperature on stress-strain behaviour. The assumptions used in constructing the new model are based on ...
