Designing 21st Century Standard Ware: The Cultural Heritage of Leach and the Potential Applications of Digital Technologies

This practice-based research investigates the potential applications of digital manufacturing technologies in the design and production of hand-made tableware at the Leach Pottery. The methodology for the research establishes an approach grounded in my previous experience as a maker that is informed by an open, experimental, emergent, and responsive framework based on Naturalistic Inquiry. A critical contextual review describes the cultural heritage of Leach which, for the purposes of the research, is developed through the Leach Pottery as a significant site, the historical production of the iconic Leach Standard Ware and the contemporary production of Leach Tableware. This is followed by an examination of Potter’s Tools in the Leach production environment, and a review of makers’ digital ceramic practice. The contextual review is followed by an explication of ‘standards’ presented through visual lineages of Standard Ware and Leach Tableware to define ‘standard’ at a design (macro) level, followed by an examination of how ‘standard’ operates at a making (micro level) level. This chapter presents new knowledge in relation to defining the visual field of Leach Pottery tableware production and its standards of design. A chapter focussed on practice presents the outcomes and analysis of my engagement with digital manufacturing technologies which resulted in the development of new tools to support Leach Tableware production and the interrogation of Leach forms, in different mediums, which led to the creation of Digital-Analogue Leach forms. The practice culminated in the design and development of new 21st century Standard Ware: a range of 9 forms, called Echo of Leach, that were developed by myself using digital and analogue methods: the designs were realised by myself, the Leach Studio, and a further four makers. The outcomes of the research were presented in a three month exhibition at the Leach Pottery in 2013. The conclusions of the research draw on the key points raised in the analysis of the practice and relate these to the approaches to making pottery that are highlighted in the cultural heritage of Leach in the contextual review. These are also discussed in relation to ways in which these findings could be taken forward into development of knowledge about Standard Ware, especially in a broader studio pottery context

Potensi Mamalia Besar sebagai Mangsa Komodo (Varanus Komodoensis Ouwens 1912) di Pulau Rinca Taman Nasional Komodo Nusa Tenggara Timur

This study aimed to reveal the potential of big mammals as komodo's preys in Rinca Island, Komodo National Park. Population density, sex ratio, age structure and distribution of the komodo's preys were collected using line transect method, and the vegetation were analyzed using line square method. A total of five species of big mammals were recorded as preys of komodo on the island, and among them were Timor deer and water buffalo which were the most important food sources for komodo. Long tailed macaque, wild horse, and wild boar were the alternative food sources for komodo. Komodo ate whenever there was the opportunity, and it usually attack animals in the savanna or water sources, since these areas were important for big mammals

Adaptive solution of truss layout optimization problems with global stability constraints

Truss layout optimization problems with global stability constraints are nonlinear and nonconvex and hence very challenging to solve, particularly when problems become large. In this paper, a relaxation of the nonlinear problem is modelled as a (linear) semidefinite programming problem for which we describe an efficient primal-dual interior point method capable of solving problems of a scale that would be prohibitively expensive to solve using standard methods. The proposed method exploits the sparse structure and low-rank property of the stiffness matrices involved, greatly reducing the computational effort required to process the associated linear systems. Moreover, an adaptive ‘member adding’ technique is employed which involves solving a sequence of much smaller problems, with the process ultimately converging on the solution for the original problem. Finally, a warm-start strategy is used when successive problems display sufficient similarity, leading to fewer interior point iterations being required. We perform several numerical experiments to show the efficiency of the method and discuss the status of the solutions obtained

Nanostructure and paramagnetic centres in diamond-like carbon: Effect of Ar dilution in PECVD process

Diamond-like carbon (DLC) films were deposited utilising plasma enhanced chemical vapour deposition (PECVD) with acetylene precursor, diluted with 0 – 45% argon. Electron paramagnetic resonance (EPR) measurements show the presence of one paramagnetic centre with no change in spin population over the range of film deposition conditions. However, the EPR linewidth decreases with increasing argon content of the precursor mix, suggesting an enhancement of motional narrowing due to an increase in electron delocalization, related to an increase in the sp2 cluster size. Atomic force microscopy (AFM) measurements indicate the surface of the DLC is formed of nanoscale asperities of material. With radii of tens of nanometres for films deposited with zero argon, the size of the features increases with the argon dilution of the acetylene. Energy dispersive x-ray analysis and electrical measurements further elucidate the changes in film structure

Effects of strain rate and moisture content on the behaviour of sand under one-dimensional compression

The influence of strain rate and moisture content on the behaviour of a quartz sand was assessed using high-pressure quasi-static (0.001 /s) and high-strain-rate (1000 /s) experiments under uniaxial strain. Quasi-static compression to axial stresses of 800 MPa was carried out alongside split Hopkinson pressure bar (SHPB) experiments to 400 MPa, where in each case lateral deformation of the specimen was prevented using a steel test box or ring, and lateral stresses were recorded. A significant increase in constrained modulus was observed between strain rates of 0.001 /s and 1000 /s, however a consistently lower Poisson's ratio in the dynamic tests minimised changes in bulk modulus. The reduction in Poisson’s ratio suggests that the stiffening of the sand in the SHPB tests is due to additional inertial confinement rather than an inherent strain-rate dependence. In the quasi-static tests the specimens behaved less stiffly with increasing moisture content, while in the dynamic tests the addition of water had little effect on the overall stiffness, causing the quasi-static and dynamic series to diverge with increasing moisture content

Experimentation and modelling of near field explosions

Repeatable experimental results and numerical work has shown that using the Jones-Wilkins-Lee (JWL) equation of state (EOS) will give very accurate results of peak pressures and impulse delivered to a rigid target at large scaled distances. However, recent experiments/numerical modelling at small scaled distances show that the JWL will overpredict peak pressures and impulse due to the assumption of (near) instantaneous energy release from detonation. The results of this experimental/numerical study are presented herein. In the experimental work PE4 spheres at two different scaled distances have been tested using an array of Hopkinson Pressure Bars (HPB) at specific points on a rigid target to measure the local pressure-time histories. From the HPB measurements, it appears that below certain scaled distances there are chemical-physical mechanisms that do not have sufficient time to contribute to the energy driving the loading mechanisms, explaining the over-prediction of the JWL. Importantly though, the experimental results show that at very small scaled distances (0.172 m/kg1/3) the test to test percentage variation is very low (5.1%); whilst at larger scaled distances (0.819 m/kg1/3) it is much higher (23.1%). This paper presents a model which describes the process by which experimental results move from repeatable to variable to repeatable as scaled distance increases from the extreme near field to far field

Repeatability of buried charge testing

The relationship between the geotechnical parameters and the impulse delivered by a charge buried shallowly (<100 mm) within a soil mass has received much attention in recent times. It has previously been demonstrated that for uniform soils a high degree of repeatability in the delivered impulse can be achieved when carefully controlling the geotechnical conditions. In this paper the authors explore the recommendations given in AEP55 regarding the testing of surrogate mine blasts using both minepots and the STANAG standard sandy gravel. With moisture content and bulk density being intrinsically coupled, using bulk density as a measure of geotechnical control and hence repeatability is questionable. A methodology for the careful preparation of the Stanag sandy gravel soil is presented along with comparative results from minepots demonstrating the comparative repeatability of both methodologies. These results are then compared with a number of other soils to allow gen-eral conclusions about the repeatability of specific soil characteristics to be drawn

Design of a split Hopkinson pressure bar with partial lateral confinement

This paper presents the design of a modified split Hopkinson pressure bar (SHPB) where partial lateral con- finement of the specimen is provided by the inertia of a fluid annulus contained in a long steel reservoir. In contrast to unconfined testing, or a constant cell pressure applied before axial loading, lateral restraint is permitted to develop throughout the axial loading: this enables the high-strain-rate shear behaviour of soils to be characterised under conditions which are more representative of buried explosive events. A pressure transducer located in the wall of the reservoir allows lateral stresses to be quantified, and a dispersion-correction technique is used to provide accurate measurements of axial stress and strain. Preliminary numerical modelling is utilised to inform the experimental design, and the capability of the apparatus is demonstrated with specimen results for a dry quartz sand
