Towards a framework for university-wide postgraduate programmes in sustainability

The role of Higher Education Institutions in addressing social, environmental, and economic challenges and opportunities in today's world is immense, complex, and vital (GUNI, 2008). Traditionally responses to sustainable development (SD) have been concentrated within specific subjects, however there has been a gradual penetration of sustainability issues into a wide spectrum of disciplines (HEA, February 2009. The definition and priorities of SD are complex and multi-layered and the challenges presented, being inherently holistic, require equal responses from all disciplines. This requires the development of a framework for University-wide, cross disciplinary teaching. The University of Strathclyde has been ranked first in the Engineering Education for Sustainable Development (ESD) Observatory Report 2008. Building on this success, work is underway to develop a university-wide, interdisciplinary Strathclyde Masters programme in Sustainability (SMS, aimed at articulating a framework for integrating flagship postgraduate courses & classes, sustainability literacy & skills training workshops. This paper summarises the theories of sustainability and its inherent interdisciplinary nature by examining current thinking in ESD. This has highlighted the need to review the current curriculum, identifying current interdisciplinary provision aligned with ESD, and implement a multistakeholder consultation process. The paper describes how these theories might be put into practice, detailing the conclusions drawn from the initial consultation process involving external organisations, students, academic staff and the university's professional services. In addition, a model 'Sustainability Map' is presented offering an overview of postgraduate provision of ESD within the institution as a whole, alongside details of the courses offered and contributing departments. The outcome of the multistakeholder consultation process, in conjunction with the 'Sustainability Map', will help inform future consultation focusing on structural refinement and the academic content of the interdisciplinary programme

Maximum Entropy/Optimal Projection (MEOP) control design synthesis: Optimal quantification of the major design tradeoffs

The underlying philosophy and motivation of the optimal projection/maximum entropy (OP/ME) stochastic modeling and reduced control design methodology for high order systems with parameter uncertainties are discussed. The OP/ME design equations for reduced-order dynamic compensation including the effect of parameter uncertainties are reviewed. The application of the methodology to several Large Space Structures (LSS) problems of representative complexity is illustrated

Creep of web ribbons

Results are reported for work in high-temperature deformatin of dendritic web ribbons, and oxygen measurement in the material

MAST flight system dynamic performance

The MAST Flight System as a test bed for large space structure control algorithms is discussed. An overview is given of the control system architecture. The actuators, the sensors, the control computer, and the baseline damping algorithm are discussed

Distributed parameter modelling of flexible spacecraft: Where's the beef?

This presentation discusses various misgivings concerning the directions and productivity of Distributed Parameter System (DPS) theory as applied to spacecraft vibration control. We try to show the need for greater cross-fertilization between DPS theorists and spacecraft control designers. We recommend a shift in research directions toward exploration of asymptotic frequency response characteristics of critical importance to control designers

Recycled Printer Filament

The purpose of this research is to examine the effects of recycling PLA filament for 3D printing on its material properties. After examining these effects, PLA and carbon fiber additives were mixed with recycled PLA pellets in different ratios to attempt to regain material properties lost in the recycling process. To complete these findings, an experiment was design and executed. The research found that tensile strength during multiple iterations of recycling remained mostly unaffected, however, the strain degraded exponentially. In the PLA additive study, high ratios of PLA additive were able to increase the strength and strain properties of the material. In the carbon fiber study, the strength and strain properties could not be restored

Electrical, structural, and chemical characterization of silicon sheet materials

Progress on the electrical, structural, and chemical characterization of silicon sheet material is reported. In the study on high temperature deformation of dendritic web ribbon, experimental creep tests were performed in four point bending under constant load conditions, and unusual behavior was observed. Also, measurements of oxygen content in web ribbon were made. Two conclusions reached are creep behavior of web which is very different from any seen for single crystal silicon and oxygen level in web silicon which is near the saturation level at the melting point of silicon

Self-Paced Endurance Performance and Cerebral Hemodynamics of the Prefrontal Cortex: A Scoping Review of Methodology and Findings.

Recent research has suggested that top-down executive function associated with the prefrontal cortex is key to the decision-making processes and pacing of endurance performance. A small but growing body of literature has investigated the neurological underpinnings of these processes by subjecting the prefrontal cortex to functional near-infrared spectroscopy (fNIRS) measurement during self-paced endurance task performance. Given that fNIRS measurement for these purposes is a relatively recent development, the principal aim of this review was to assess the methodological rigor and findings of this body of research. We performed a systematic literature search to collate research assessing prefrontal cortex oxygenation via fNIRS during self-paced endurance performance. A total of 17 studies met the criteria for inclusion. We then extracted information concerning the methodology and findings from the studies reviewed. Promisingly, most of the reviewed studies reported having adopted commonplace and feasible best practice guidelines. However, a lack of adherence to these guidelines was evident in some areas. For instance, there was little evidence of measures to tackle and remove artifacts from data. Lastly, the reviewed studies provide insight into the significance of cerebral oxygenation to endurance performance and the role of the prefrontal cortex in pacing behavior. Therefore, future research that better follows the guidelines presented will help advance our understanding of the role of the brain in endurance performance and aid in the development of techniques to improve or maintain prefrontal cortex (PFC) oxygenation to help bolster endurance performance
