Animating Geographies Of Making: Embodied Slow Scholarship For Participant-Researchers Of Maker Cultures And Material Work, Chontel A. Carr, Christopher R. Gibson Jan 2017

Animating Geographies Of Making: Embodied Slow Scholarship For Participant-Researchers Of Maker Cultures And Material Work, Chontel A. Carr, Christopher R. Gibson

Faculty of Social Sciences - Papers (Archive)

Accounts of making as a social and economic practice, and as a process of material transformation, are accumulating both within and beyond geography. In this article, we turn our attention to how geographers have engaged viscerally with the labour process of making, by putting their own bodies to work, as makers themselves, or alongside those of research participants. Such embodied interventions extend academic understandings of the everyday, embodied accumulation of skill and tacit knowledge, as well as offering an alternative, methodologically transparent approach to nonrepresentational modes of writing. We review how geographers interested in making have found ways in which …

Now we are Four gives us a comprehensive look at how kiwi kids from the Growing Up in New Zealand study are faring. In particular, we can see how the situation of mothers changes when children pass from infancy to early childhood. The biggest shift for most children is that they now attend early childhood education, and most are reported to be generally happy and healthy and spending time getting to know their peers. This means that we also see greater employment of mothers, leading to improved economic circumstances for these households. Nearly half of this generation of mothers live …

Perceived Public Transport Infrastructure Modifies The Association Between Public Transport Use And Mental Health: Multilevel Analyses From The United Kingdom, Xiaoqi Feng, Zhiqiang Feng, Thomas E. Astell-Burt

Faculty of Social Sciences - Papers (Archive)

Aims Investments to promote public transport utilisation are being championed to achieve sustainable development, but the potential co-benefits for mental health are comparatively under-researched. We hypothesised that frequent users of public transport would be more likely to have better mental health (possibly due to increased levels of physical activity), but among the more frequent users, less favourable perceptions of public transport infrastructure (PPTI) could have a negative influence on mental health. Methods Multilevel linear and logistic regressions were fitted on 30,214 participants in the UK Household Longitudinal Study with lagged PPTI and confounder measures at baseline and indicators of active …

Further Examining The Relationship Between Mental Toughness And Dispositional Flow In Sport: A Mediation Analysis, Patricia C. Jackman, Lee Crust, Christian F. Swann

Faculty of Social Sciences - Papers (Archive)

The purpose of the study was to further examine the relationship between mental toughness (MT) and dispositional flow in sport. A sample of 256 athletes (M age = 23.65 years, SD = 5.43), competing at international (n = 59), national (n = 77), and club/university (n = 120) levels completed questionnaires assessing MT and dispositional flow. A significant and positive correlation was found between MT and dispositional flow (r = 0.50, p < 0.001). Mediation analysis revealed that MT had a significant direct effect on the flow dimensions of challenge-skills balance, clear goals, unambiguous feedback, sense of control and concentration on the task at hand, and significant indirect effects on concentration on the task at hand, sense of control, loss of self-consciousness, action-awareness merging and autotelic experience. Findings suggest that MT has direct and indirect effects on the characteristics of flow, offering new insights regarding optimal human functioning

Low Voltage Ride-Through Enhancement Of Dfig-Based Wind Turbine Using Dc Link Switchable Resistive Type Fault Current Limiter, Seyed Behzad Naderi, Michael Negnevitsky, Amin Jalilian, Mehrdad Tarafdar Hagh, Kashem M. Muttaqi Jan 2017

Low Voltage Ride-Through Enhancement Of Dfig-Based Wind Turbine Using Dc Link Switchable Resistive Type Fault Current Limiter, Seyed Behzad Naderi, Michael Negnevitsky, Amin Jalilian, Mehrdad Tarafdar Hagh, Kashem M. Muttaqi

Faculty of Engineering and Information Sciences - Papers: Part A

Doubly-fed induction generator (DFIG)-based wind turbines utilise small-scale voltage sourced converters with a limited overcurrent withstand capability, which makes the DFIG-based wind turbines very vulnerable to grid faults. Often, modern DFIG systems employ a crowbar protection at the rotor circuit to protect the rotor side converter (RSC) during grid faults. This method converts the DFIG to a squirrel cage induction generator, which does not comply with the new grid codes. The recent grid codes need wind turbines to stay connected to the utility grid during and after power system faults, especially in high penetration level of wind power. Furthermore, the …

Micromechanics-Based Investigation Of Fouled Ballast Using Large-Scale Triaxial Tests And Discrete Element Modeling, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers: Part A

Railway ballast comprises unbounded discrete grains that are often used to form a load-bearing platform for tracks. Ballast degradation as trains pass over the tracks and infiltration of external fines including slurried (pumped) fine subgrade soils are two of the main reasons for ballast fouling. Fouling causes tracks to settle and also reduces the load-bearing capacity, which is associated with a reduction in internal friction and increased lateral spreading of the ballast layer. This paper presents a study of mobilized friction angle, volumetric behavior, and associated evolutions of contact and fabric anisotropy of fouled ballast subjected to monotonic triaxial loading …

Displaced Hardness Peak Phenomenon In Heat-Affected Zone Of Welded Quenched And Tempered Em812 Steel, Druce P. Dunne, W Pang

Faculty of Engineering and Information Sciences - Papers: Part A

Investigations of microstructural and hardness gradients in the heat-affected zone (HAZ) of quenched and tempered (Q&T) steels have indicated that peak hardness does not occur in the grain-coarsened heat-affected zone (GCHAZ) adjacent to the fusion boundary, which is typical of ferritic steels, but corresponds more closely to the grain-refined region (GRHAZ). This phenomenon, the displaced hardness peak (DHP) effect, is considered to arise when the hardenability of the steel is high enough to result in the same microstructure in the GC and GR heat-affected zones, except for significant refinement of the microstructure of the GRHAZ, which increases the hardness and …

A Decomposition Approach Via Fourier Sine Transform For Valuing American Knock-Out Options With Rebates, Nhat Tan Le, Duy-Minh Dang, Tran Vu Khanh

Faculty of Engineering and Information Sciences - Papers: Part A

We present an innovative decomposition approach for computing the price and the hedging parameters of American knock-out options with a time-dependent rebate. Our approach is built upon: (i) the Fourier sine transform applied to the partial differential equation with a finite time-dependent spatial domain that governs the option price, and (ii) the decomposition technique that partitions the price of the option into that of the European counterpart and an early exercise premium. Our analytic representations can generalize a number of existing decomposition formulas for some European-style and American-style options. A complexity analysis of the method, together with numerical results, show …

Direct Immobilization Of Laccase On Titania Nanoparticles From Crude Enzyme Extracts Of P. Ostreatus Culture For Micro-Pollutant Degradation, Chao Ji, Ngoc Luong Nguyen, Jingwei Hou, Faisal I. Hai, Vicki Chen

Faculty of Engineering and Information Sciences - Papers: Part A

Enzymatic treatment can effectively degrade recalcitrant micro-pollutants in wastewater. However, its industrial application is constrained by the high cost of the purified enzyme preparations. This work introduces a novel technique to directly immobilize the in-house crude enzyme extracts (from P. ostreatus) onto the functionalized TiO2 nanoparticle surface. Comprehensive investigations were carried out to understand the interactions between complex crude enzyme extracts and the immobilization support. By simple dilution of the crude enzyme extract, the immobilization efficiency can be significantly improved. The resultant biocatalytic nanoparticles had comparable performance to the immobilized purified commercial enzymes. Finally, the micropollutant degradation capability …

Pulsed lasers operating in the mid-infrared (3–20 μm) are important for a wide range of applications in sensing, spectroscopy, imaging and communications. Despite recent advances with mid-infrared gain platforms, the lack of a capable pulse generation mechanism remains a significant technological challenge. Here we show that bulk Dirac fermions in molecular beam epitaxy grown crystalline Cd3As2, a three-dimensional topological Dirac semimetal, constitutes an exceptional ultrafast optical switching mechanism for the mid-infrared. Significantly, we show robust and effective tuning of the scattering channels of Dirac fermions via an element doping approach, where photocarrier relaxation times are found …

The new era of intra-fraction dose tracking in radiation therapy delivery demands new dosimetry methods, whereby a moving frame of reference as a function of time may be required. This introduces a new paradigm into radiation therapy dose verification. The term we propose to describe this is dynamic dosimaging, which by our definition is tracking the location of a dosimeter array in real time during on-line radiation dose acquisition.

Use Of Rubber Mats To Improve The Deformation And Degradation Behavior Of Rail Ballast Under Cyclic Loading, Sinniah Navaratnarajah, Buddhima Indraratna

Faculty of Engineering and Information Sciences - Papers: Part B

The deterioration of a rail track due to large dynamic wheel loads is inevitable over the years and leads to frequent, high-cost maintenance. This problem is more critical in isolated rail track locations such as bridges and tunnels, where the substructure is much stiffer than the surface track assembly. One measure used to minimize track deterioration is geosynthetic inclusions such as rubber mats under the layer of ballast. In this study, cyclic loads from fast and heavy-haul trains were simulated on stiffer track foundation conditions using a largescale process simulation triaxial (prismoidal) apparatus (PSPTA) to investigate the performance of ballast …
