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 …

Tourism is growing rapidly throughout the world, including nature‐based tourism, but natural habitats are shrinking. How do we avoid damaging what is left as an increasing number of visitors wish to experience nature or enjoy adventure or relaxation in natural surroundings? This issue explores various environmental impact factors, from the physical effects of trampling through the disturbance of wildlife to the attitudes of visitors and how well‐run tourism ventures might modify their behavior.


Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge Jan 2019

Metamorphic Robustness Testing: Exposing Hidden Defects In Citation Statistics And Journal Impact Factors, Zhi Q. Zhou, T.H. Tse, Matt Witheridge

Faculty of Engineering and Information Sciences - Papers: Part B

We propose a robustness testing approach for software systems that process large amounts of data. Our method usesmetamorphic relations to check software output for erroneous input in the absence of a tangible test oracle. We use this technique to testtwo major citation database systems: Scopus and the Web of Science. We report a surprising finding that the inclusion of hyphensin paper titles impedes citation counts, and that this is a result of the lack of robustness of the citation database systems in handlinghyphenated paper titles. Our results are valid for the entire literature as well as for individual fields such …
