Distributed Generation For Minimization Of Power Losses In Distribution Systems, Kashem M. Muttaqi, An D. T Le, Michael Negnevitsky, Gerard Ledwich

Faculty of Engineering and Information Sciences - Papers: Part A

Appropriate size and location of distributed generation (DG) play a significant role in minimizing power losses in distribution systems. This paper represents techniques to minimize power losses in a distribution feeder by optimizing DG model in terms of size, location and operating point of DG. Sensitivity analysis for power losses in terms of DG size and DG operating point has been performed. The proposed sensitivity indices can indicate the changes in power losses with respect to DG current injection. The proposed techniques have been developed with considering load characteristics and representing loads with constant impedance and constant current models, separately. …

Infants' Discrimination Of Faces By Using Biological Motion Cues, Janine Spencer, Justin O'Brien, Alan Johnston, Harold C. Hill

Faculty of Health and Behavioural Sciences - Papers (Archive)

We report two experiments in which we used animated averaged faces to examine infants' ability to perceive and discriminate facial motion. The faces were generated by using the motion recorded from the faces of volunteers while they spoke. We tested infants aged 4 ^ 8 months to assess their ability to discriminate facial motion sequences (condition 1) and discrim- inate the faces of individuals (condition 2). Infants were habituated to one sequence with the motion of one actor speaking one phrase. Following habituation, infants were presented with the same sequence together with motion from a different actor (condition 1), or …

Visual Correlates Of Prosodic Contrastive Focus In French: Description And Inter-Speaker Variability, Marion Dohen, Helene Loevenbruck, Harold C. Hill

Faculty of Health and Behavioural Sciences - Papers (Archive)

This study is a follow-up of previous studies we conducted on the visible articulatory correlates of French prosodic contrastive focus. A two speaker analysis using an automatic lip-tracking device had shown that these correlates existed and were used in visual perception. However the articulatory strategies depended on the speaker. The purpose of this study was thus to extend the analysis to other speakers, examine the similarities and variabilities and try to identify global tendencies. We recorded five speakers of French with a 3D optical tracker using a 13 sentence (subject-verb-object) corpus and four focus conditions (S, V, O or neutral). …

Effect Of Decorrelation On 3-D Grating Detection With Static And Dynamic Random-Dot Stereograms, Stephen A. Palmisano, Robert S. Allison, Ian P. Howard

Faculty of Health and Behavioural Sciences - Papers (Archive)

Three experiments examined the effects of image decorrelation on the stereoscopic detection of sinusoidal depth gratings in static anddynamic random-dot stereograms (RDS). Detection was found to tolerate greater levels of image decorrelation as: (i) density increasedfrom 23 to 676 dots/deg2; (ii) spatial frequency decreased from 0.88 to 0.22 cpd; (iii) amplitude increased above 0.5 arcmin; and (iv) dotlifetime decreased from 1.6 s (static RDS) to 80 ms (dynamic RDS). In each case, the specific pattern of tolerance to decorrelation couldbe explained by its consequences for image sampling, filtering, and the influence of depth noise.

These principles and methods are combined to illustrate how one may evaluate the risk of …

Scaling Of Na+, K+-Atpase Molecular Activity And Membrane Fatty Acid Composition In Mammalian And Avian Hearts, Anthony J. Hulbert, Paul Else, Kurt Haga, Nigel Turner

Faculty of Health and Behavioural Sciences - Papers (Archive)

We have examined Na⁺,K⁺‐ATPase molecular activity and membrane fatty acid composition in the heart of six mammalian and eight avian species ranging in size from 30 g in mice to 280 kg in cattle and 13 g in zebra finches to 35 kg in emus, respectively. Na⁺,K⁺‐ATPase activity scaled negatively with body mass in both mammals and birds. In small mammals, the elevated enzyme activity was related to allometric changes in both the concentration and molecular activity (turnover rate) of Na⁺,K⁺‐ATPase enzymes, while in small birds, higher Na …

Illusory Scene Distortion Occurs During Perceived Self-Rotation In Roll, Stephen A. Palmisano, Ian P. Howard, Robert S. Allison

Faculty of Health and Behavioural Sciences - Papers (Archive)

We report a novel illusory distortion of the visual scene, which became apparent during both: (i) observer rotation inside a furnishedstationary room; and (ii) room rotation about the stationary observer. While this distortion had several manifestations, the most commonexperience was that scenery near Wxation appeared to sometimes lead and other times lag more peripheral scenery. Across a series ofexperiments, we eliminated explanations based on eye-movements, distance misperception, peripheral aliasing, diVerential motion sensitivityand adaptation. We found that these illusory scene distortions occurred only when the observer perceived (real or illusory) changesin self-tilt and maintained a stable Wxation.

Cambodian Journalism 'Flying Blind', Eric Loo

Faculty of Creative Arts - Papers (Archive)

With freedom comes great responsibility, says a famous movie script. Not so with the Cambodian press. The many publications owned by as many factions are unrestrained in slandering their adversaries. Everyone’s fair media prey – except for the King. Unbridled reporting with no clear ethical guidelines often sees public decency being violated, which has caused near zero public faith in the media.

Stereoscopic Visualization And Editing Of Automatic Abdominal Aortic Aneurysms (Aaa) Measurements For Stent Graft Planning, Luping Zhou, Yaping Wang, Lin-Chia Goh, Ralf A. Kockro, Luis Serra

Faculty of Engineering and Information Sciences - Papers: Part A

For stent graft selection in the treatment of abdominal aortic aneurysms (AAA) anatomic considerations are important. They determine GO/NO-GO of the treatment and help customize the stent. Current systems for AAA stent insertion planning based on pre-operative CT and MR of the patient do not provide an intuitive interface to view the resulting measurements against the pre-operative CT/MR. Subsequent modifications of the measurements are frequent when automatic algorithms are inaccurate. However, 3D editing is difficult to achieve because of the limitations of monoscopic displays and 2D interface. In this paper, we present a system for automatic AAA measurement and interactive …

Unadulterated Spectral Function Of Low-Energy Quasiparticles In Bi2sr2cacu2o8+Delta, D V. Evtushinsky, A A. Kordyuk, S V. Borisenko, V B. Zabolotnyy, M Knupfer, J Fink, B Büchner, A. V. Pan, A Erb, C T. Lin, H Berger

Faculty of Engineering and Information Sciences - Papers: Part A

Fitting the momentum distribution photoemission spectra to the Voigt profile appears to be a robust procedure to purify the interaction effects from the experimental resolution. In application to Bi2Sr2CaCu2O8+delta high-Tc cuprates, the procedure reveals the true scattering rate at low binding energies and temperatures, and consequently, the true value of the elastic scattering. Reaching the minimal value ~16 meV, the elastic scattering does not reveal a systematic dependence on doping level, but is rather sensitive to impurity concentration and can be explained by the forward scattering on out-of-plane impurities. The inelastic scattering is found to form well-defined quasiparticles with the …

For an arbitrary real number with convergents p0 q0 , p1 q1 , p2 q2 , . . ., b(n+qi)c−bnc is equal to pi, and so is independent of n, except at a small specified number of values of n. For fixed n, this relation holds for all or for all except a finite number of values of i.

Spatial Prediction For Massive Datasets, Noel A. Cressie, Gardar Johannesson

Faculty of Engineering and Information Sciences - Papers: Part A

Remotely sensed spatio-temporal datasets on the order of megabytes to terrabytes are becoming more common. For example, polar-orbiting satellites observe Earth from space, monitoring the Earth's atmospheric, oceanic, and terrestrial processes, and generate massive amounts of environmental data. The current generation of satellites, such as the National Aeronautic and Space Administration's (NASA) Earth Observing System (EOS) Terra and Aqua satellites, generate about 1.5 terrabytes of data per day. In the USA, there are remote-sensing projects in preparation that will dwarf even these datasets. NASA, the National Oceanic and Atmospheric Administration (NOAA), and the Department of Defense (DoD) have created the …

Gait Analysis Of Low-Cost Flexible-Shank Transtibial Prostheses, Winson Lee, Ming Zhang, Peggy Chan, David A. Boone

Faculty of Engineering and Information Sciences - Papers: Part A

The latest lower-limb prosthetic designs have been incorporated with dynamic elastic response (DER) components to enhance prosthesis flexibility, which are suggested to be beneficial to gait. Although DER prosthetic. feet are preferred by most transtibial amputees and their benefits to gait are supported by some biomechanical studies, many are still utilizing the simple conventional solid ankle cushioned heel (SACH) designs because of the lower cost. The monolimb, a transtibial prosthesis with the socket and the shank molded from a single piece of thermoplastic material, perhaps is an alternative to DER feet for providing flexibility at the shank. In addition to …
