Faculty of Engineering and Information Sciences - Papers: Part B
© 2020 Elsevier Inc. The consensus tracking of singular multi-agent systems (MASs) with Lipschitz-type nonlinearities and exogenous disturbances is researched in this paper. Governed by a Markov chain, the network interaction randomly switches in a directed graph set, where the directed spanning tree is not contained in each graph while exists in the union rooting at the leader node. By utilizing a collection of in-neighbors’ information that involves communication delay, the intention is to design a protocol such that the resultant consensus error system is stochastic admissible with an H∞ disturbance attenuation level. Based on algebraic graph theory, stochastic admissibility …
Tracking The 10be-26al Source-Area Signal In Sediment-Routing Systems Of Arid Central Australia, Martin Struck, John D. Jansen, Toshiyuki Fujioka, Alexandru Tiberiu Codilean, David Fink, Reka H. Fulop, Klaus M. Wilcken, David M. Price, Steven Kotevski, L Keith Fifield, John Chappell

Sediment-routing systems continuously transfer information and mass from eroding source areas to depositional sinks. Understanding how these systems alter environmental signals is critical when it comes to inferring source-area properties from the sedimentary record. We measure cosmogenic 10Be and 26Al along three large sediment-routing systems ( ∼ 100 000 km2) in central Australia with the aim of tracking downstream variations in 10Be-26Al inventories and identifying the factors responsible for these variations. By comparing 56 new cosmogenic 10Be and 26Al measurements in stream sediments with matching data (n = 55) from source areas, we show that 10Be-26Al inventories in hillslope bedrock …

Tracking Eye Movements To Gain Insights Into An Older Reader's Reading Practices, Jessica Mantei, Lisa K. Kervin
Faculty of Social Sciences - Papers (Archive)
Perhaps you've met Patrick? Patrick (pseudonym) is in Year 5. He is a reader who struggles to cope with the reading demands of the Year 5 classroom. His teacher reports he is reluctant to read any genre of text, refuses to read aloud with the teacher or with another support person and becomes quite agitated when he encounters something he does not know in his reading. The reading challenges Patrick faces are more common in an emergent reader, but perhaps more difficult to address with an older reader where ineffective practices have become learned. In this paper, we share the …

Target Tracking Algorithm Using Angular Point Matching Combined With Compressive Tracking, Jing Luo, Tingting Dong, Chunyuan Zi, Chunbo Xiu, Huixin Tian, Jiangtao Xi
Faculty of Engineering and Information Sciences - Papers: Part A
To solve the problems of tracking errors such as target missing that emerged in compressive tracking (CT) algorithm due to factors such as pose variation, illumination change, and occlusion, a novel tracking algorithm combined angular point matching with compressive tracking (APMCCT) was proposed. A sparse measurement matrix was adopted to extract the Haar-like features. The offset of the predicted target position was integrated into the angular point matching, and the new target position was calculated. Furthermore, the updating mechanism of the template was optimized. Experiments on different video sequences have shown that the proposed APMCCT performs better than CT algorithm …

In Australia, large organisations are required to report their direct, Scope 1, and indirect, Scope 2, Green-House Gas (GHG) emissions annually through the National Government Emissions Reporting Scheme (NGERS). These organisations must therefore find the resources and means to measure these aspects of their Environmental Footprint. SMEs are not yet required to report to NGERS and most do not have the knowledge and resources to do it. Many, however, would like to know more about their environmental impact and how they can reduce it in simple, cost-effective ways.

Translocating birds to a new area of habitat to restore or supplement depleted populations may pose a significant threat to the translocated individuals. While for many species, translocated individuals appear to move larger distances than resident animals, species with poor dispersal capacity may be restricted in movements and translocation methods may need to accommodate differences in movements to ensure success. In this study, designed to provide insights to inform our broader programme of translocations in New South Wales, Australia, we investigated post-release movements in the endangered, semi-flightless Eastern Bristlebird (Dasyornis brachypterus). We predicted that movements would be minimal, with few …

Faculty of Informatics - Papers (Archive)
Time delays are often encountered by practical control systems while they are acquiring, processing, communicating, and sending signals. Time delays may affect the system stability and degrade the control system performance if they are not properly dealt with. Taking the classical robot control problem as an example, the significant effect of time delay on the closed-loop system stability has been highlighted in the bilateral teleoperation, where the communication delay transmitted through a network medium has been received widespread attention and different approaches have been proposed to address this problem (Hokayem and Spong, 2006). In addition, examples like processing delays in …
A Singularity Free Trajectory Tracking Method For The Cooperative Working Of Multi-Arm Robots Using Screw Theory, Emre Sariyildiz, Hakan Temeltas
A Singularity Free Trajectory Tracking Method For The Cooperative Working Of Multi-Arm Robots Using Screw Theory, Emre Sariyildiz, Hakan Temeltas
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper we present a singularity free trajectory tracking method for the cooperative working of multi-arm robot manipulators. It is based on an inverse kinematic transformation which determines the manipulator's joint angles corresponding to the end-effector trajectory given in the task space. The kinematic problem of multi-arm robot system is solved by using screw theory and quaternion algebra. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. Dual-quaternion is the most compact and efficient dual operator to express screw displacement. Inverse kinematic solutions …

Differential kinematic is one of the most important solution methods in robot kinematics. The main advantage of the differential kinematic method is that it can be easily implemented any kind of mechanisms. Also, an accurate and efficient kinematic based trajectory tracking application can be easily implemented by using this method. In differential kinematic method, we use Jacobian as a mapping operator in the velocity space. Inversion of Jacobian matrix transforms the desired trajectory velocities, which are the linear and angular velocities of the end effector, into the joint velocities. The joint velocities are required to be integrated to obtain the …

Differential kinematic has a wide range application area in robot kinematics. The main advantage of the differential kinematic is that it can be easily implemented any kind of mechanisms. In differential kinematic method, Jacobian is used as a mapping operator in the velocity space. The joint velocities are required to be integrated to obtain the pose of the robot manipulator. This integration can be evaluated by using numerical integration methods, since the inverse kinematic equations are highly complex and nonlinear. Thus, the performances of the numerical integration methods affect the trajectory tracking application. This paper compares the performances of numerical …

Compressive Evaluation In Human Motion Tracking, Yifan Lu, Lei Wang, Richard Hartley, Hongdong Li, Dan Xu
Faculty of Engineering and Information Sciences - Papers: Part A
The powerful theory of compressive sensing enables an efficient way to recover sparse or compressible signals from non-adaptive, sub-Nyquist-rate linear measurements. In particular, it has been shown that random projections can well approximate an isometry, provided that the number of linear measurements is no less than twice of the sparsity level of the signal. Inspired by these, we propose a compressive anneal particle filter to exploit sparsity existing in image-based human motion tracking. Instead of performing full signal recovery, we evaluate the observation likelihood directly in the compressive domain of the observed images. Moreover, we introduce a progressive multilevel wavelet …

This article introduces a new particle filtering approach for object tracking in video sequences. The projective particle filter uses a linear fractional transformation, which projects the trajectory of an object from the real world onto the camera plane, thus providing a better estimate of the object position. In the proposed particle filter, samples are drawn from an importance density integrating the linear fractional transformation. This provides a better coverage of the feature space and yields a finer estimate of the posterior density. Experiments conducted on traffic video surveillance sequences show that the variance of the estimated trajectory is reduced, resulting …

Simple, Robust And Accurate Head-Pose Tracking Using A Single Camera, Simon Meers, Koren Ward, Ian Piper
Faculty of Informatics - Papers (Archive)
This paper describes an inexpensive, robust method for tracking the head position and orientation of the user by using a single low-cost USB camera and infrared light emitting diodes concealed within spectacle frames worn by the user. Unlike gaze and head-pose tracking systems which rely on high-resolution stereo cameras and complex image processing hardware and software to find and track facial features on the user, the proposed system is able to efficiently locate and track the head's orientation and distance relative to the camera with little processing. Due to the infrared light emitting diodes having fixed geometry, the system does …

The Global Positioning System (GPS) is increasingly being adopted by private and public enterprise to track and monitor humans for location-based services (LBS). Some of these applications include personal locators for children, the elderly or those suffering from Alzheimer’s or memory loss, and the monitoring of parolees for law enforcement, security or personal protection purposes. The continual miniaturization of the GPS chipset means that receivers can take the form of wristwatches, mini mobiles and bracelets, with the ability to pinpoint the longitude and latitude of a subject 24/7/365. This paper employs usability context analyses to draw out the emerging ethical …

This paper proposes a robust control methodology for piezoelectric actuation systems to track specified motion trajectories. This is motivated by the search for an effective control strategy to deal with the problem of nonlinear behaviour in the piezoelectric actuation systems. The basic concept associated with this approach lies in the specification of a target performance and the formulation of a robust control scheme for the system to ensure the convergence of the position tracking error to zero in the presence of parametric uncertainties and hysteresis effect inclusive of other un-modelled disturbances. Stability of the control system is proven theoretically and …

Faculty of Engineering and Information Sciences - Papers: Part A
The tracking of the time-varying channel is crucial for MIMO-OFDM wireless communication systems. Aiming at doubly-selective fading MIMO channels, we present a novel pilot pattern and the corresponding adaptive channel tracking algorithm. Compared with the traditional pilot patterns, the new pattern has higher frequency efficiency and is more suitable for large transmit arrays. The computational complexity, frequency efficiency and BER performance of the system assisted by the proposed channel tracking scheme are analyzed. Simulation results demonstrate that the proposed scheme can track the timevarying channel effectively

Comparing Particle Swarms For Tracking Extrema In Dynamic Environments, Xiaodong Li, Hoa K. Dam
Faculty of Engineering and Information Sciences - Papers: Part A
This work presents a comparative study of particle swarm models on their abilities to track extrema in dynamic environments. A standard PSO, two randomized PSOs, and a fine-grained PSO are evaluated in non-trivial multimodal dynamic environments involving small constant step changes, different large step changes, and chaotic step changes of the extrema. DF1 proposed by Morrison and De Jong is used to generate these three types of dynamics (1999). Our results indicate that PSO and its variants are able to perform reasonably well in a 2-dimensional variable space, whereas perform well to a less extent in a 10-dimensional variable space. …
