Social Carpooling-Based Road Congestion Mitigation: A Three-Level Analysis, Peng Chen, Da Hye Lee, Wei Li, Thang Nguyen, Luca Quadrifoglio, Philip Winters, Xiankui Yang

Research Reports

Different from Transportation Network Companies and shared-car providers, social carpooling is personalized incentives-based and smartphone-enabled peer-to-peer ridesharing. Social carpooling emerges as a community-based strategy to reduce car ownership and mitigate congestion. It facilitates the transition from solo driving to effective carpooling by matching individuals’ travel demand in space and time. Personalized incentives, such as real-time information, travel feedback, and monetary incentives, are leveraged to spur the change. This project investigates the impact of social carpooling on users’ travel behavior and the system’s performance. The empirical data are supported by Metropia, which is a social carpooling platform enabling ride-match. Three research …

Fuzzy Mathematics Under Non-Minimal "And"-Operations (T-Norms): Equivalence Leads To Metric, Order Leads To Kinematic Metric, Topology Leads To Area Or Volume, Purbita Jana, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Most formulas analyzed in fuzzy mathematics assume -- explicitly or implicitly -- that the corresponding "and"-operation (t-norm) is the simplest minimum operation. In this paper, we analyze what happens if instead, we use other "and"-operations. It turns out that for such operations, a fuzzification of a mathematical theory naturally leads to a more complex mathematical setting: fuzzification of equivalence relation leads to metric, fuzzification of order leads to kinematic metric, and fuzzification of topology leads to area or volume.

Predation In Many Dimensions: Spatial Context Is Important For Meaningful Functional Response Experiments, Steven A. Juliano, Jonah A. Goughnour, Geoffrey D. Ower

Faculty Publications – Biological Sciences

For simplicity and to minimize variation, functional response experiments frequently use environments of simple physical structure and small size. Less attention is paid to similarity of the experimental environment to the natural environment where predation occurs. Assumptions about predator and prey use of space are often implied in the choice of experimental environment. We illustrate how these assumptions may affect conclusions with an experiment testing how arena size affects a functional response. Toxorhynchites rutilus preyed upon larval Culex restuans in containers differing in volume by 15x, but spanning a similar range of prey/liter. The most plausible Type II model included …

Common Visual Representations As A Source For Misconceptions Of Preservice Teachers In A Geometry Connection Course, Mile Krajcevski, Ruthmae Sears

Teaching and Learning Faculty Publications

In this paper, we demonstrate how atypical visual representations of a triangle, square or a parallelogram may hinder students’ understanding of a median and altitude. We analyze responses and reasoning given by 16 preservice middle school teachers in a Geometry Connection class. Particularly, the data were garnered from three specific questions posed on a cumulative final exam, which focused on computing and comparing areas of parallelograms, and triangles represented by atypical images. We use the notions of concept image and concept definition as our theoretical framework for an analysis of the students’ responses. Our findings have implication on how typical …

International Environmental Law Principles Relevant To Exploitation Activity In The Area, Robin M. Warner

Faculty of Law, Humanities and the Arts - Papers (Archive)

The International Seabed Authority is responsible for providing effective protection for the marine environment from the harmful effects of activities in the Area under Article 145 of UNCLOS. To meet this challenge, it must determine the relevant environmental governance principles applicable to each stage of an exploration and exploitation activity and how they can be operationalized in practical terms. This article discusses some key principles of international environmental law and management which are potentially relevant to the exploitation process and in particular the approval of a plan of work for exploitation activities. It also examines the potential legal thresholds for …

The findings of the study demonstrated that to a certain extent the Minecraft activity supported the transfer of knowledge from preservice teachers’ mathematics content knowledge to their mathematics pedagogical and instructional practice knowledge. Preservice teachers appreciated the usefulness and effectiveness of the Minecraft activity …

Channel Autocorrelation-Based Dynamic Slot Scheduling For Body Area Networks, Hongyun Zhang, Farzad Safaei, Le Chung Tran

Faculty of Engineering and Information Sciences - Papers: Part B

As a promising technology in the context of m-health and e-medical, wireless body area networks (WBANs) have a stringent requirement in terms of transmission reliability. Meanwhile, the wireless channel in WBANs is prone to deep fading due to multiple reasons, such as shadowing by the body, reflection, diffraction, and interference. To meet the challenge in transmission reliability, the dynamic slot scheduling (DSS) methods have attracted considerable interest in recent years. DSS method does not require extra hardware or software overhead on the sensor side. Instead, the hub optimizes the time-division multiple access slots by selecting the best permutation at the …

Unraveling The Blue Paradox: Incomplete Analysis Yields Incorrect Conclusions About Phoenix Islands Protected Area Closure, Quentin A. Hanich, Randi Rotjan, Transform Aqorau, Megan Bailey, Brooke M. Campbell, Noella Gray, Rebecca Gruby, John Hampton, Yoshitaka Ota, Hannah Parris, Chris Reid, Rashid Sumaila, Wilf Swartz

Faculty of Law, Humanities and the Arts - Papers (Archive)

In PNAS, McDermott et al. (1) analyze a 2014-2016 central Pacific fishing surge, focusing on the Phoenix Islands Protected Area (PIPA) inside the Kiribati exclusive economic zone (EEZ). The authors incorrectly attribute the surge to the anticipated industrial fishing closure of PIPA and describe the phenomenon as a blue paradox (i.e., an unintended negative consequence of a conservation policy). However, a broader analysis demonstrates that this surge was unrelated to the closure of PIPA and was due to a strong El Ni~no event that created a fishing surge across multiple EEZs and high seas, not just PIPA (2).

Personality Disorder: A Mental Health Priority Area, Brin F. S Grenyer, Fiona Y. Ng, Michelle L. Townsend, Sathya Rao

Effects Of Climate Oscillations On Wildland Fire Potential In The Continental United States, Shelby A. Mason, Peter E. Hamlington, Benjamin D. Hamlington, W. Matt Jolly, Chad M. Hoffman

OES Faculty Publications

The effects of climate oscillations on spatial and temporal variations in wildland fire potential in the continental U.S. are examined from 1979 to 2015 using cyclostationary empirical orthogonal functions (CSEOFs). The CSEOF analysis isolates effects associated with the modulated annual cycle and the El Nino-Southern Oscillation (ENSO). The results show that, in early summer, wildland fire potential is reduced in the southwest during El Nino but is increased in the northwest, with opposite trends for La Nina. In late summer, El Nino is associated with increased wildland fire potential in the southwest. Relative to the mean, the largest impacts of …

Outlier Robust Small-Area Estimation Under Spatial Correlation, Timo Schmid, Nikos Tzavidis, Ralf Munnich, Raymond L. Chambers

Faculty of Engineering and Information Sciences - Papers: Part A

Modern systems of official statistics require the estimation and publication of business statistics for disaggregated domains, for example, industry domains and geographical regions. Outlier robust methods have proven to be useful for small-area estimation. Recently proposed outlier robust model-based small-area methods assume, however, uncorrelated random effects. Spatial dependencies, resulting from similar industry domains or geographic regions, often occur. In this paper, we propose an outlier robust small-area methodology that allows for the presence of spatial correlation in the data. In particular, we present a robust predictive methodology that incorporates the potential spatial impact from other areas (domains) on the small …

Correlation Of Impedance And Effective Electrode Area Of Dextran Sulfate Doped Pedot Modified Electrodes, Alexander R. Harris, Robyn C. Hutchinson, Paul J. Molino, Robert M. I Kapsa, Graeme M. Clark, Antonio G. Paolini, Gordon G. Wallace

Australian Institute for Innovative Materials - Papers

The impedance of electrodes at 1 kHz is typically reported to assess the signal-to-noise ratio of neural recording electrodes. The impedance response of platinum electrodes modified by poly-3,4-ethylenedioxythiophene doped with dextran sulfate has been examined. The modified electrodes have lower impedance at low and intermediate frequencies compared to unmodified electrodes. The impedance and phase angle at low frequencies is strongly correlated with the electrode area. The geometric and linear diffusion charge densities of the modified electrodes are also dependent on the electrode area and impedance at low frequencies. A 3 time constant equivalent circuit provided a better fit to the …

Effective Area And Charge Density Of Chondroitin Sulphate Doped Pedot Modified Electrodes, Alexander R. Harris, Paul J. Molino, Antonio G. Paolini, Gordon G. Wallace

Australian Institute for Innovative Materials - Papers

Neural electrodes have been coated with electrodeposited poly-3,4-ethylenedioxythiophene doped with chondroitin sulphate. Optical and electrochemical methods were used to determine the effective electrode area, charge injection capacity and charge density of the modified electrodes. Deposition times of 15 to 60 s slightly increased the geometric and steady state diffusion electroactive areas while the linear diffusion electroactive area grew significantly, indicating an increase in electrode roughness. The effective electrode area and charge injection capacity were significantly smaller than PEDOT doped with previously tested dopants. In contrast to other dopant ions, the charge density determined from the geometric and steady state diffusion …

Probe Current Determination In Analytical Tem/Stem And Its Application To The Characterization Of Large Area Eds Detectors, David R. G Mitchell, Mitchell John Bromley Nancarrow

Australian Institute for Innovative Materials - Papers

A simple procedure, which enables accurate measurement of transmission electron microscopy (TEM)/STEM probe currents using an energy loss spectrometer drift tube is described. The currents obtained are compared with those measured on the fluorescent screen to enable the losses due to secondary and backscattered electrons to be determined. The current values obtained from the drift tube allow the correction of fluorescent screen current densities to yield true current. They also enable CCD conversion efficiencies to be obtained, which in turn allows images to be calibrated in terms of electron fluence. Using probes of known current in conjunction with a NiO …

Enhanced Frequency Response Strategy For Pmsg Based Wind Energy Conversion System Using Ultracapacitor In Remote Area Power Supply Systems, Yingjie Tan, Kashem M. Muttaqi

Faculty of Engineering and Information Sciences - Papers: Part A

The high penetration level of wind energy, and non-responsive nature of power electronic interfaced wind energy conversion system (WECS) during frequency variations may create significant stress on conventional generators in a wind-diesel hybrid remote area power supply (RAPS) system. Hence, it is a necessity for WECS to provide frequency support. However, conventional frequency control strategies being used for WECS may impose a severe stress to wind turbines. In this paper, an enhanced frequency response strategy is proposed for the permanent magnet synchronous generator (PMSG) based WECS to regulate RAPS system frequency jointly with its integrated ultracapacitors. The proposed frequency response …

Adaptive Space-Time-Frequency-Coded Uwb System For Wireless Body Area Network, Miftadi Sudjai, Le Chung Tran, Farzad Safaei

Faculty of Engineering and Information Sciences - Papers: Part A

Wireless body area networks (WBAN) emerge as one of the main research streams for future wireless communications. One of the candidates for the WBAN physical layer is multiband orthogonal frequency division multiplexing ultra-wideband (MB-OFDM UWB) technology. However, despite its high data rate feature, it performs poorly in the very dispersive WBAN channel. To improve its performance, this paper proposes two novel mechanisms. First, the space-time-frequency coding (STFC) is introduced into MB-OFDM UWB system in order to enhance the diversity order, resulting in a substantial improvement in the average error performance compared to the conventional MB-OFDM UWB system. Nevertheless, the performance …

Optical And Electrochemical Methods For Determining The Effective Area And Charge Density Of Conducting Polymer Modified Electrodes For Neural Stimulation, Alexander R. Harris, Paul Molino, Robert M. I Kapsa, Graeme M. Clarke, Antonio Paolini, Gordon G. Wallace

Australian Institute for Innovative Materials - Papers

Neural stimulation is used in the cochlear implant, bionic eye, and deep brain stimulation, which involves implantation of an array of electrodes into a patient's brain. The current passed through the electrodes is used to provide sensory queues or reduce symptoms associated with movement disorders and increasingly for psychological and pain therapies. Poor control of electrode properties can lead to suboptimal performance; however, there are currently no standard methods to assess them, including the electrode area and charge density. Here we demonstrate optical and electrochemical methods for measuring these electrode properties and show the charge density is dependent on electrode …
