Static And Dynamic Behaviours Of Railway Prestressed Concrete Sleepers With Longitudinal Through Hole, C Ngamkhanong, Sakdirat Kaewunruen, Alex M. Remennikov Jan 2017

Static And Dynamic Behaviours Of Railway Prestressed Concrete Sleepers With Longitudinal Through Hole, C Ngamkhanong, Sakdirat Kaewunruen, Alex M. Remennikov

Faculty of Engineering and Information Sciences - Papers: Part B

As the crosstie beam in railway track systems, the prestressed concrete sleepers (or railroad ties) are principally designed in order to carry wheel loads from the rails to the ground. Their design takes into account static and dynamic loading conditions. It is evident that prestressed concrete has played a significant role as to maintain the high endurance of the sleepers under low to moderate repeated impact loads. In spite of the most common use of the prestressed concrete sleepers in railway tracks, there have always been many demands from rail engineers to improve serviceability and functionality of concrete sleepers. For …

Designing And Using Self-Paced Tutorials: Lessons From The Pilot, Sasha Nikolic, Raad Raad

Faculty of Engineering and Information Sciences - Papers: Part B

CONTEXT The literature has shown the importance of students developing threshold concepts and undertaking formative assessment. There are also suggestions within the literature that many students will not undertake beneficial activities that display no direct reward in terms of grades. A new electrical engineering common first year subject with 450 students resulted in bottle necks for providing effective feedback. An online self-paced tutorial resource was created that advanced students through core threshold concepts, supplemented with non-assessed activities that guided students through the process of solving problems and understanding class material

On Performance Of Analog Least Mean Square Loop For Self-Interference Cancellation In In-Band Full-Duplex Ofdm Systems, Anh Tuyen Le, Le Chung Tran, Xiaojing Huang Jan 2017

On Performance Of Analog Least Mean Square Loop For Self-Interference Cancellation In In-Band Full-Duplex Ofdm Systems, Anh Tuyen Le, Le Chung Tran, Xiaojing Huang

Faculty of Engineering and Information Sciences - Papers: Part B

This paper evaluates the performance of an analog least mean square (ALMS) loop employed to cancel self-interference in in-band full-duplex (IBFD) orthogonal frequency division multiplexing (OFDM) systems. Cyclostationary analysis is applied to investigate the behavior of the ALMS filter. It is revealed that the performance of the ALMS filter for OFDM systems primarily depends on windowing function rather than pulse shaping as in single carrier systems. It is also noticed that the ALMS loop in OFDM systems provides a much higher level of sel-interference (SI) suppression because OFDM signals lead to reduced the error of the interference channel modelling with …

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper we examine a technique for developing prognostic image characteristics, termed radiomics, for non-small cell lung cancer based on a tumour edge region-based analysis. Texture features were extracted from the rind of the tumour in a publicly available 3D CT data set to predict two-year survival. The derived models were compared against the previous methods of training radiomic signatures that are descriptive of the whole tumour volume. Radiomic features derived solely from regions external, but neighbouring, the tumour were shown to also have prognostic value. By using additional texture features an increase in accuracy, of 3%, is shown …

A New Integral Equation Formulation For American Put Options, Song-Ping Zhu, Xin-Jiang He, Xiaoping Lu Jan 2017

A New Integral Equation Formulation For American Put Options, Song-Ping Zhu, Xin-Jiang He, Xiaoping Lu

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, a completely new integral equation for the price of an American put option as well as its optimal exercise price is successfully derived. Compared to existing integral equations for pricing American options, the new integral formulation has two distinguishable advantages: (i) it is in a form of one-dimensional integral, and (ii) it is in a form that is free from any discontinuity and singularities associated with the optimal exercise boundary at the expiry time. These rather unique features have led to a significant enhancement of the computational accuracy and efficiency as shown in the examples.

A Review Of Phosphorus Partition Relations For Use In Basic Oxygen Steelmaking, Phillip Drain, Brian J. Monaghan, Guangqing Zhang, Raymond Longbottom, Michael W. Chapman, Sheng Chew

Faculty of Engineering and Information Sciences - Papers: Part B

Phosphorus removal in basic oxygen steelmaking is a significant problem for integrated steelmakers. Phosphorus removal is required due to its deleterious effect on the mechanical properties of steel. However, this is progressively becoming more difficult due to the increasing phosphorus content of many iron ores. Many studies have investigated dephosphorisation and published empirical phosphorus partition (LP) equations for a range of conditions. The structure of these equations has been used to develop a new partition relation that allows the effect of minor slag constituents such as TiO2, Al2O3 and V2O5 …

Automated Approach For The Surface Profile Measurement Of Moving Objects Based On Psp, Lei Lu, Yi Ding, Yinsen Luan, Yongkai Yin, Qiong Liu, Jiangtao Xi

Faculty of Engineering and Information Sciences - Papers: Part B

Phase shifting profilometry can achieve high accuracy for the 3D shape measurement of static object. Errors will be introduced when the object is moved during the movement. The fundamental reason causing the above issue is: PSP requires multiple fringe patterns but the reconstruction model does not include the object movement information. This paper proposes a new method to automatically measure the 3D shape of the rigid object with arbitrary 2D movement. Firstly, the object movement is tracked by the SIFT algorithm and the rotation matrix and translation vector describing the movement are estimated. Then, with the reconstruction model including movement …

Micro-Displacement Reconstruction Using A Laser Self-Mixing Grating Interferometer With Multiple-Diffraction, Dongmei Guo, Liheng Shi, Yanguang Yu, Wei Xia, Ming Wang

Faculty of Engineering and Information Sciences - Papers: Part B

In this paper, we demonstrated an improved laser self-mixing grating interferometer (SMGI) with auto-collimation design which can avoid the disturbance from the light feedback of the zero-order diffraction beam. In order to obtain higher optical subdivision, SMGI with multiple-diffraction is implemented. Both theoretical analysis and experimental work show that the proposed system for displacement measurement can achieve high sensitivity and low measurement uncertainty. Using the proposed system, different forms of micro-displacement signals applied on the target (grating) have been reconstructed with accuracy of a few nanometers. The work presented in this paper provides a good way to achieve robust and …

Faculty of Engineering and Information Sciences - Papers: Part B

In the capillary venules, blood cells auto-separate with red blood cells aggregating near the centre of vessel and the nucleated cells marginating toward the wall of vessel. In this experiment, we used cell margination to help enrich the Jurkat cells via a groove-based channel which provides a vertical expansion-contraction structure, wherein the red blood cells invade the grooves and push the Jurkat cells to the bottom of the channel. The secondary flows induced by the anisotropic grooves bring the Jurkat cells to the right sidewall. Rigid, 13-µm diameter polystyrene particles were spiked into the whole blood to verify the operating …

Something Wonderful In My Back Yard: The Social Impetus For Group Self- Building, Emma Elizabeth Heffernan, Pieter De Wilde

Faculty of Engineering and Information Sciences - Papers: Part B

The housing crisis in the United Kingdom, as Barker (2004) identifies, has become shorthand for a chronic lack of suitable and affordable housing - in both the home ownership and rental sectors - and the undersupply and diminishment of social housing stock (Barker, 2004; Jefferys et al., 2014). What has also become clear is that the mainstream housebuilding sector - speculative housing development - has not risen to the task of ameliorating this crisis. Consequently, there is increasing marginalisation within the housing and land economy, with many people finding that their housing needs cannot be met by the sector. This …

Bigl: Biochemically Intuitive Generalized Loewe Null Model For Prediction Of The Expected Combined Effect Compatible With Partial Agonism And Antagonism, Koen Van Der Borght, Annelies Tourny, Rytis Bagdziunas, Olivier Thas, Maxim Nazarov, Heather Turner, Bie M. P Verbist, Hugo Ceulemans Jan 2017

Bigl: Biochemically Intuitive Generalized Loewe Null Model For Prediction Of The Expected Combined Effect Compatible With Partial Agonism And Antagonism, Koen Van Der Borght, Annelies Tourny, Rytis Bagdziunas, Olivier Thas, Maxim Nazarov, Heather Turner, Bie M. P Verbist, Hugo Ceulemans

Faculty of Engineering and Information Sciences - Papers: Part B

Clinical efficacy regularly requires the combination of drugs. For an early estimation of the clinical value of (potentially many) combinations of pharmacologic compounds during discovery, the observed combination effect is typically compared to that expected under a null model. Mechanistic accuracy of that null model is not aspired to; to the contrary, combinations that deviate favorably from the model (and thereby disprove its accuracy) are prioritized. Arguably the most popular null model is the Loewe Additivity model, which conceptually maps any assay under study to a (virtual) single-step enzymatic reaction. It is easy-to-interpret and requires no other information than the …

Curvature Contraction Flows In The Sphere, James A. Mccoy Jan 2017

Curvature Contraction Flows In The Sphere, James A. Mccoy

Faculty of Engineering and Information Sciences - Papers: Part B

We show that convex surfaces in an ambient three-sphere contract to round points in finite time under fully nonlinear, degree one homogeneous curvature flows, with no concavity condition on the speed. The result extends to convex axially symmetric hypersurfaces of the (n+1)-dimensional sphere. Using a different pinching function we also obtain the analogous results for contraction by Gauss curvature.

In this paper, we propose a two-round k-out-of-n oblivious transfer scheme with the minimum communication cost. In our proposed scheme, the messages sent by the receiver R to the sender S consist of only three elements, which is independent of n and k, while the messages from S to R are (n+1) elements when the sender holds n secrets. Our scheme features a nice property of universal parameter, where the system parameter can be used by all senders and receivers. The proposed k-out-of-n oblivious transfer scheme is the most efficient two-round scheme in terms of the number of messages transferred …

An Osmotic Membrane Bioreactor-Membrane Distillation System For Simultaneous Wastewater Reuse And Seawater Desalination: Performance And Implications, Wenhai Luo, Hop V. Phan, Guoxue Li, Faisal I. Hai, William E. Price, Menachem Elimelech, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part B

In this study, we demonstrate the potential of an osmotic membrane bioreactor (OMBR)-membrane distillation (MD) hybrid system for simultaneous wastewater reuse and seawater desalination. A stable OMBR water flux of approximately 6 L m-2 h-1 was achieved when using MD to regenerate the seawater draw solution. Water production by the MD process was higher than that from OMBR to desalinate additional seawater and thus account for draw solute loss due to the reverse salt flux. Amplicon sequencing on the Miseq Illumina platform evidenced bacterial acclimatization to salinity build-up in the bioreactor, though there was a reduction in the …
