The 2003 R.M. Hardy lecture: Soil parameters for numerical analysis in clay
(2006-02-01)Engineers in geotechnical practice work on increasingly complex problems with increasingly powerful numerical tools. Effective solutions to design problems need good information about the site and parameters (or functions) ... -
Ab initio analysis of C-H and C-C stretching intensities in Raman spectra of hydrocarbons
(2005-03-31)Molecular polarizability and changes in the polarizability associated with the stretch of C-C and C-H bonds have been calculated for thirty-four saturated hydrocarbons, including the series of n-alkanes to C15, as well as ... -
Acoustic discharge measurements for the performance testing of low-head hydroelectric turbines under disturbed flow conditions
(2000-02-29)The detection, measurement, and characterization of frazil ice particles is a necessary first step in advancing our understanding of frazil ice processes as well as improving models. The detection of frazil ice has been ... -
Adaptive fair subcarrier/rate allocation in multirate OFDMA networks: Radio link level queuing performance analysis
(2006-11-30)This paper presents a semi-analytical methodology for radio link level performance analysis in a multirate "orthogonal frequency-division multiple-access" (OFDMA) network with adaptive fair rate allocation. Multirate ... -
Analysis of finite-micro strip structures using surface equivalence principle and multiple network theory (SEMN)
(2002-08-31)Two techniques based on electric and magnetic field integral equation (EFIE and MFIE) formulations of surface equilalent principle and multiple network theory (SEMN) method are developed for the analysis of finite microstrip ... -
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 ... -
Analysis of restriction fragment length polymorphisms in the ribosomal DNA of a selection of anaerobic chytrids
(2000-07-31)Anaerobic chytrid strains (representing four genera and seven species based on morphological characters), obtained from a variety of hosts, were analysed for variability within the 5' terminal segment of the ribosomal large ... -
Analysis of TCP performance under joint rate and power adaptation in cellular WCDMA networks
(2004-05-31)To improve the spectral efficiency while meeting the radio link level quality of service requirements such as the bit-error-rate (BER) requirements for the different wireless services, transmission rate and power corresponding ... -
An analytical approach to providing controllable differentiated quality of service in Web servers
(2005-11-30)Provisioning quality of service (QoS) in Web servers has gained immense importance because Web servers are a major part of the Internet. To deliver the pledged QoS, Web service providers need control over the allocation ... -
Antiviral activity of arylnaphthalene and aryldihydronaphthalene lignans
(2003-03-31)A practical method for large scale synthesis of 1-arylnaphthalene and 1-aryl-1,2-dihydronaphthalene lignans is described. The method makes use of the classic Stobbe condensation followed by regioselective reactions that ... -
Artificial inoculation with Armillaria ostoyae in established conifers stressed by defoliation, planting, and thinning in Newfoundland
(2000-11-30)Armillaria ostoyae (Romagnesi) Herink causes root disease in conifers of the northern hemisphere. Pathogenicity tests of established conifer trees with A. ostoyae, has never been done in the boreal forest. Seven forest ... -
The association of caveolae, actin, and the dystrophin-glycoprotein complex: a role in smooth muscle phenotype and function?
(2005-10-31)Smooth muscle cells exhibit phenotypic and mechanical plasticity. During maturation, signalling pathways controlling actin dynamics modulate contractile apparatus-associated gene transcription and contractile apparatus ... -
Attenuation of the serotonin-induced increase in intracellular calcium in rat aortic smooth muscle cells by sarpogrelate
(2003-11-30)Although serotonin (5-HT) induced proliferation of vascular smooth muscle cells is considered to involve changes in intracellular Ca2+ ([Ca2+](i)), the mechanism of Ca2+ mobilization by 5-HT is not well defined. In this ... -
Bandwidth enhancement and size reduction of microstrip slot antennas
(2005-03-31)Reduced size microstrip monopole slot antennas with different slot shapes-straight, L and inverted T, and placed on a small ground plane, are investigated. The ground plane size is 50 mm x 80 mm, which is about the size ... -
Beam focusing properties of circular monopole array antenna on a finite ground plane
(2005-10-31)This paper presents the investigation results on the beam focusing properties of a wire circular monopole array (CMA) antenna consisting of six-elements on a finite ground plane, by exciting more than one monopole at a ... -
