Ideals Of Steinberg Algebras Of Strongly Effective Groupoids, With Applications To Leavitt Path Algebras, Lisa Orloff Clark, Cain Edie-Mitchell, Astrid An Huef, Aidan Sims
Ideals Of Steinberg Algebras Of Strongly Effective Groupoids, With Applications To Leavitt Path Algebras, Lisa Orloff Clark, Cain Edie-Mitchell, Astrid An Huef, Aidan Sims
Faculty of Engineering and Information Sciences - Papers: Part B
We consider the ideal structure of Steinberg algebras over a commutative ring with identity. We focus on Hausdorff groupoids that are strongly effective in the sense that their reductions to closed subspaces of their unit spaces are all effective. For such a groupoid, we completely describe the ideal lattice of the associated Steinberg algebra over any commutative ring with identity. Our results are new even for the special case of Leavitt path algebras; so we describe explicitly what they say in this context, and give two concrete examples.

Improved Performance Of Ballasted Tracks Under Impact Loading By Recycled Rubber Mats, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn
Faculty of Engineering and Information Sciences - Papers: Part B
Ballasted tracks at transition locations such as approaches to bridges and road crossings experience increasing degradation and deformation due to dynamic and high impact forces, a key factor that decreases the stability and longevity of railroads. One solution to minimise ballast degradation at the transition zones is using rubber energy absorbing drainage sheets (READS) manufactured from recycled tyres. When placed beneath the ballast layer, READS distributes the load over wider area and attenuate of the load over a longer duration thus decreasing maximum stress, apart from reducing the energy transferred to the ballast and other substructure components. Subsequently, the track …
Assessment Of Radio-Induced Damage In Endothelial Cells Irradiated With 40 Kvp, 220 Kvp, And 4 Mv X-Rays By Means Of Micro And Nanodosimetric Calculations, Nicolas Tang, Marta Bueno, Sylvain Meylan, Yann Perrot, Hoang Tran, Amelie Freneau, Morgane Dos Santos, Aurelie Vaurijoux, Gaetan Gruel, Mario Bernal, Marie Bordage, Dimitris Emfietzoglou, Ziad Francis, Susanna Guatelli, Vladimir Ivanchenko, Mathieu Karamitros, Ioanna Kyriakou, Wook Shin, Sebastien Incerti, Carmen Villagrasa

2019 by the authors. Licensee MDPI, Basel, Switzerland. The objective of this work was to study the differences in terms of early biological effects that might exist between different X-rays energies by using a mechanistic approach. To this end, radiobiological experiments exposing cell monolayers to three X-ray energies were performed in order to assess the yields of early DNA damage, in particular of double-strand breaks (DSBs). The simulation of these irradiations was set in order to understand the differences in the obtained experimental results. Hence, simulated results in terms of microdosimetric spectra and early DSB induction were analyzed and compared …

An In-Situ Synchrotron Study Of The B2→B19′ Phase Transformation In A Ni-Ti Alloy Subjected To Uniaxial Monotonic Tension, Xiaohui Bian, Ahmed A. Saleh, Peter Lynch, Christopher H. J Davies, Elena V. Pereloma, Azdiar Adil Gazder
Faculty of Engineering and Information Sciences - Papers: Part B
A cold-drawn and annealed 56Ni-44Ti wt% alloy was subjected to in-situ uniaxial monotonic tension in a synchrotron. Spatially resolved diffraction data was acquired along the gauge length by pausing the loading at five select macroscopic strains within the stress plateau region. This enables tracking localised transformation phenomena by sub-dividing the gauge length into transformation band, untransformed and apparently transformed regions. Within the macroscopic stress plateau region: (i) the highly strained B2 phase within the propagating transformation band and apparently transformed regions produces a relaxation of the B2 phase within the untransformed region. (ii) The newly formed B19′ grain families exhibit …

Railway tracks are conventionally built on compacted ballast and structural fill layers placed above the natural (subgrade) foundation. However, during train operations, track deteriorations occur progressively due to ballast degradation. The associated track deformation is usually accompanied by a reduction in both load bearing capacity and drainage, apart from imposing frequent track maintenance. Suitable ground improvement techniques involving plastic inclusions (e.g., geogrids) and energy absorbing materials (e.g., rubber products) to enhance the stability and longevity of tracks have become increasingly popular. This paper presents the outcomes from innovative research and development measures into the use of plastic and rubber elements …

Faculty of Engineering and Information Sciences - Papers: Part B
Critical wastewater events such as sewer main blockages or overflows are often not detected until after the fact. These events can be costly, from both an environmental impact and monetary standpoint. A standalone, portable radar device allowing non-invasive benchmarking of sewer pumping station (SPS) pumps is presented. Further, by configuring and deploying a complete Low Power Wide Area Network (LPWAN), Shoalhaven Water (SW) now has the opportunity to create "Internet of Things" (IoT)-capable devices that offer freedom from the reliance on mobile network providers, whilst avoiding congestion on the existing Supervisory Control and Data Acquisition (SCADA) telemetry backbone. This network …

A Data Dependency And Access Threshold Based Replication Strategy For Multi-Cloud Workflow Applications, Fei Xie, Jun Yan, Jun Shen
A Data Dependency And Access Threshold Based Replication Strategy For Multi-Cloud Workflow Applications, Fei Xie, Jun Yan, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part B
Data replication is one of the significant sub-areas of data management in cloud based workflows. Data-intensive workflow applications can gain great benefits from cloud environments and usually need data management strategies to manage large amounts of data. At the same time, multi-cloud environments become more and more popular. We propose a cost-effective and threshold-based data replication strategy with the consideration of both data dependency and data access times for data-intensive workflows in the multi-cloud environment. Finally, the simulation results show that our approach can greatly reduce total cost of data-intensive workflow applications by considering both of data dependency and data …

An Alternative Form To Calibrate The Correlated Stein-Stein Option Pricing Model, Xinjiang He, Song-Ping Zhu
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, we present an alternative form of the correlated Stein-Stein option pricing model, which preserves the analytic tractability of the original form and also demonstrates certain advantage for model implementation in practice. We shall show, through an empirical study, that this alternative form generally outperforms the original Stein-Stein form for the selected set of data, demonstrating that it can serve as a good competitor to the original Stein-Stein form in real markets.

Latest researches predict the cosmic rays exposure during long space missions outside the Earth's geomagnetic sphere, as to the Moon and Mars, can double the cancer risk. The minimization of risk associated with radiation exposure in the Low Earth Orbit (LEO) is of great interest for astronauts of the International Space Station (ISS). This risk is due to radiation hazard and can be predicted by measurement of the dose equivalent produced by the radiation environment inside of the spacecraft. Since more than 15 years ago, the Centre For Medical Radiation Physics (CMRP), University of Wollongong, is developing silicon based microdosimeters …

Metamorphic Relations For Data Validation: A Case Study Of Translated Text Messages, Boyang Yan, Brian Yecies, Zhi Q. Zhou
Faculty of Engineering and Information Sciences - Papers: Part B
In conventional metamorphic testing, metamorphic relations (MRs) are identified as necessary properties of a computer program's intended functionality, whereby violations of MRs reveal faults in the program - under the assumption that the source and follow-up inputs (test cases used in metamorphic testing) are valid. In the present study, the authors argue that MRs can also be used to validate and assess the quality of the program's input data - under the assumption that the source or follow-up inputs can be inappropriately generated. Using this new perspective, a case study in the natural language processing domain is used to explore …

Fibre Optic Dosimetry In Synchrotron Microbeam Radiation Therapy, James Archer, Enbang Li, Anatoly B. Rosenfeld, Michael L. F Lerch
Faculty of Engineering and Information Sciences - Papers: Part B
Synchrotron microbeam radiation therapy is a novel pre-clinical therapy method that uses high brilliance, spatially fractionated, low energy x-rays to deliver a very high dose rate. A conventional spatial fractionation for these beams is 50 μm microbeam width at 400 μm peak-to-peak separation. To perform dosimetry on these beams, a dosimeter with a high spatial resolution is required. We present a plastic scintillator fibre optic dosimeter that has been demonstrated to be able to resolve the microbeam structure. The advantages of such a dosimeter is the water equivalence, passive components exposed to the radiation field, relatively inexpensive components and simple …

Leveraging Smote In A Two-Layer Model For Prediction Of Protein-Protein Interactions, Huaming Chen, Lei Wang, Chi-Hung Chi, Jun Shen
Faculty of Engineering and Information Sciences - Papers: Part B
The research of the mechanisms of infectious diseases between host and pathogens remains a hot topic. It takes stock of the interactions data between host and pathogens, including proteins and genomes, to facilitate the discoveries and prediction of underlying mechanisms. However, the incomplete protein-protein interactions data impediment the advances in this exploration and solicit the wet-lab experiments to examine and verify the latent interactions. Although there have been numerous studies trying to leverage the computational models, especially machine learning models, the performances of these models were not good enough to produce high-fidelity candidates of interactions data due to the nature …

In China, one or several ultrathin soft coal sublayers are widely developed in the coal seam. Therefore, a method of using hydraulic flushing in soft sublayer to enhance the gas extraction in these particular coal seams is developed in this work. We first established a new fully coupled gas extraction model by combing gas diffusion, gas flow, and a permeability model that considers the effect of stress change and plastic failure. By adopting this model, the gas extraction enhancement mechanism and its main influence factors were studied using the numerical simulation method based on the engineering and geological background in …

Effects Of Foot Orthoses On Dynamic Balance And Basketball Free-Throw Accuracy Before And After Physical Fatigue, Wing-Kai Lam, Winson Lee, Siu-On Ng, Yi Zheng
Faculty of Engineering and Information Sciences - Papers: Part B
While it is not uncommon for athletes to use foot orthoses to relieve pain and improve sports performance, little has been known about their effects on basketball performance. Free-throw basketball shooting is very important. However, fatigue deteriorates postural balance which might decrease free-throw shooting performance. This study investigated the effects of foot orthoses on dynamic balance and accuracy performance during free-throw shooting before and after physical fatigue was induced. Thirteen male recreational basketball players were tested with two foot orthoses (medial-arch support versus flat control) and fatigue conditions (before and after fatigue), when they performed standard free-throw shooting on a …

Faculty of Engineering and Information Sciences - Papers: Part B
Energy efficiency is providing the same services consuming less energy. Less energy means less energy bill and less greenhouse emissions. Bhutan presents a unique scenario in promoting the use of energy efficiency equipment and investments. Bhutan enjoys availability of adequate low cost hydropower energy resource that is green and clean and enjoys cheap electrical energy. To aggravate the situation, the domestic tariffs are subsidized and even free up to 100 units in rural parts of the country. Export tariffs are determined independently according to entirely different principles. However for cooking, Bhutan imports LPG (Liquefied Petroleum Gas) from India. With increasing …
A Derivative-Free Vu-Algorithm For Convex Finite-Max Problems, Warren L. Hare, Chayne Planiden, Claudia Sagastizabal
A Derivative-Free Vu-Algorithm For Convex Finite-Max Problems, Warren L. Hare, Chayne Planiden, Claudia Sagastizabal
Faculty of Engineering and Information Sciences - Papers: Part B
The VU-algorithm is a superlinearly convergent method for minimizing nonsmooth, convex functions. At each iteration, the algorithm works with a certain V-space and its orthogonal u-space, such that the nonsmoothness of the objective function is concentrated on its projection onto the V-space, and on the U-space the projection is smooth. This structure allows for an alternation between a Newton-like step where the function is smooth, and a proximal-point step that is used to find iterates with promising VU-decompositions. We establish a derivative-free variant of the VU-algorithm for convex finite-max objective functions. We show global …
Thermionic Enhanced Heat Transfer In Electronic Devices Based On 3d Dirac Materials, Sunchao Huang, R A. Lewis, C Zhang
Thermionic Enhanced Heat Transfer In Electronic Devices Based On 3d Dirac Materials, Sunchao Huang, R A. Lewis, C Zhang
Faculty of Engineering and Information Sciences - Papers: Part B
We calculate the heat transfer from electronic devices based on three-dimensional Dirac materials without and with thermionic cooling. Without thermionic cooling, the internal temperature of the devices is at best equal to and usually higher than the temperature of the surrounding environment. However, when thermionic cooling is employed to transport heat, the internal temperature can be considerably lower than the environmental temperature. In the proposed thermionic cooling process, the energy efficiency can be as high as 75% of the Carnot efficiency.

Purpose:We introduce a technique that employs a 2D detector in transmission mode (TM) to verify dose maps at a depth of dmaxin Solid Water. TM measurements, when taken at a different surface‐to‐detector distance (SDD), allow for the area at dmax(in which the dose map is calculated) to be adjusted.Methods:We considered the detector prototype"MP512"(an array of 512 diode‐sensitive volumes, 2 mm spatial resolution). Measurements in transmission mode were taken at SDDs in the range from 0.3 to 24 cm. Dose mode (DM) measurements were made at dmaxin Solid Water. We considered radiation fields in the range from 2x2cm2to 10x10 cm2, produced …

A Semianalytical Formula For European Options Under A Hybrid Heston-Cox-Ingersoll-Ross Model With Regime Switching, Xinjiang He, Wenting Chen
Faculty of Engineering and Information Sciences - Papers: Part B
In this paper, we consider the pricing of European options under a regime-switching Heston-Cox-Ingersoll-Ross (CIR) hybrid model, where the mean-reversion levels of both the stochastic volatility and interest rate are assumed to change among different states. Albeit difficult, we have still managed to derive an semianalytical pricing formula for European options after the generalized moment generating function of this particular model is worked out. Numerical experiments are also carried out to demonstrate the accuracy of the newly derived formula as well as the influence of the introduction of the regime-switching mechanics on option prices. Finally, through a preliminary empirical study, …
