The addition of a calender machine to a pyrolytic graphite sheet production plant
… of adding a new calender machine to AvCarb Material Solutions' pyrolytic graphite production plant. Before the machine could be used for mass production, several experiments needed to be conducted to better understand the capabilities of the machine. A process control procedure was designed …

Physical Performance of Geomembranes Used in Heap Leach Pad Applications
… arising from indentations caused from the material placed both below and above the geomembrane are quantified, and the potential for puncturing is investigated. Experiments were conducted on 1.5 mm high-density (HDPE) and liner low density polyethylene (LLDPE) geomembranes for applied …

Simultaneous Lot sizing and Lead-time Setting (SLLS)Via Queuing Theory and Heuristic search
Materials requirements planning (MRP) is a widely used method for production planning and scheduling. Planned lead-time (PLT) and lot size are two of the input parameters for MRP systems, which determine planned order release dates. Presently, planned lead-time and lot size are estimated using …

Characterization of Delamination in 2099-T861 Aluminum-Lithium
… cyclic deformation of both uniaxial and torsion experiments. Many of the experimental observations, such as rate insensitivity and crystallographic orientation, were incorporated into a cyclically stable crystal plasticity framework with rate independent kinematic hardening. It was hypothesized …

What the Earth Remembers: Landscape and Materiality in the work of Sally Mann, Mark Bradford, and Tacita Dean
… triangulates the complex relationships among materiality, place, and history in works of contemporary landscape. I analyze three case studies: Sally Mann’s photographs of the American South, Mark Bradford’s iconoclastic paintings after the Gettysburg Cyclorama, and Tacita Dean’s film of the …

'The emotional wardrobe': a fashion perspective on the integration of technology and clothing
… integration of electronic technology and smart materials on the body. However, it is not fashion designers who are exploiting this emerging area but interaction design, performance art and electronic and computing technologists. 'The Emotional Wardrobe' is a practice-based research project that …

Nanoindentation of Gold Single Crystals
… mechanical properties of very small volumes of material. Gold single crystals were chosen as a model system for surface modification studies, because of the electrochemical advantages and the simple structure of the material. Experiments on these samples displayed a spectrum of residual …

Defect tolerance assessment of silicon nitride in rolling contact.
… nitride balls – ‘star’ type defects and ‘missing material’. The main objective of this research is to determine failure modes and the critical or tolerable defect sizes for rolling bearing applications. This is achieved by means of both experimental and numerical techniques (for finding crack …

Machine Learning Potentials for Perovskite Science - Applications and Development
… is an essential tool in modern chemistry and materials science. The main limitation of ab initio methods, however, has always been their high computational cost. Electronic structure methods such as density functional theory or coupled cluster are simply too slow to directly simulate the …

Evaluation of anaerobic membrane bioreactors and hydrothermal catalytic gasification for enhanced conversion of organic wastes to renewable fuels
… by eliminating the need to store a pyrophoric material. Experiments showed that the activity of in-situ synthesized Ra-Ni catalyst was equivalent to or higher than that synthesized ex-situ. This could possibly be explained by the beneficial presence of bayerite during in-situ synthesis. Based …
