Woodside Energy Ltd. Cossack Pioneer Facility Engineering Team
No full textCossack Pioneer is a floating production storage and offloading vessel located 112 km North West of Karratha. This report details the work performed during a 16 week internship with Woodside Energy Ltd working in the Cossack Pioneer Facility Engineering Team. This Perth based team provides engineering support to the production facility. The report incorporates a description of the facility and topsides process and discusses the systems used for process control.
The earlier work performed during the internship focussed on small engineering design and control system modifications for the instrumentation and control group within the facility engineering team. Partway through the internship focus changed and the challenging role of Facility Control Engineer for Cossack Pioneer was assumed during the absence of the facility Senior Control Engineer. The report provides discussion of learning outcomes acheived and experience gained during the internship
PLASMA SHAPE AND FUELING DEPENDENCE ON THE SMALL ELMS REGIME IN TCV AND AUG
No full textA series of experiments has been conducted at AUG and TCV to disentangle the role of fueling, plasma triangularity and closeness to a double null (DN) configuration for the onset of the small ELM regime. At AUG, the role of the SOL density has been revisited. Indeed, it turns out that a large density SOL is not a sufficient condition to achieve the type-II (small) ELM regime. This has been demonstrated with a constant gas fueled plasma close to DN which has been progressively shifted down, relaxing therefore the closeness to DN at constant. As the plasma is moved down, Type-I ELMs are progressively restored, finally being the unique ELM regime. It is observed that not only the pedestal top profiles are unchanged, but also the SOL profiles remained unaffected by transition from Type-II to Type-I ELMs. We conclude that the separatrix density is not the unique key parameter and it is hypothesized that the local magnetic shear, modified by the closeness to DN, could play an important role. A small ELM regime with good confinement has been achieved at TCV, a full carbon machine featuring an open divertor. A systematic scan in the fueling rate has been done for both medium and high triangularity shapes. For the latter case, a configuration close to a DN configuration, the stored energy and the pedestal top pressure increase by 5% and 30% respectively compared to the medium triangularity case. For both shapes, as the D2 fueling is increased, the Type-I ELM frequency decreases and small ELMs are observed in between large ones. Finally for the high triangularity, at the maximum fueling rate, the large ELMs are fully suppressed and only the small ELMs remain. As observed in JET and AUG, the pedestal pressure degrades with increasing fueling, up to 40% for the high triangularity scenario, although the stored energy remains almost unchanged. It is also observed that, for both shapes, the density at the separatrix increases with the fueling rate, reaching ne,sep/nG ~0.3 at ne,av/nG~0.75. The small ELM regime at TCV is associated with a coherent mode at about 30 kHz seen by the magnetic probes located at the outboard midplane. The outer target heat loads from IR tomography are reduced by more than a factor of 5 when transiting towards the small ELM regime.SP
Team perfectionism and team performance: A prospective study
No full textPerfectionism is a personality characteristic that has been found to predict sports performance in athletes. To date, however, research has exclusively examined this relationship at an individual level (i.e., athletes’ perfectionism predicting their personal performance). The current study extends this research to team sports by examining whether, when manifested at team level, perfectionism predicts team performance. A sample of 231 competitive rowers from 36 boats completed measures of self-oriented, team-oriented, and team-prescribed perfectionism prior to competing against one another in a 4-day rowing competition. Strong within-boat similarities in the levels of team members’ team-oriented perfectionism supported the existence of collective team-oriented perfectionism at the boat level. Two-level latent growth curve modeling of day-by-day boat performance showed that team-oriented perfectionism positively predicted the position of the boat in mid-competition and the linear improvement in position. The findings suggest that imposing perfectionistic standards on team members may drive teams to greater levels of performance
Report of an independent peer review of A forest management strategy for the proposed Coquille Forest submitted to the Coquille Indian Tribe by the Independent Scientific Advisory Team (ISAT)
No full text"[T]he [Coquille Indian] Tribe requested that the State of Oregon assemble a team of independent scientists to peer review the forest management strategy proposed by the ISAT. The purpose of the independent peer review would be to: 1) assess the degree to which the two major goals assigned by the Tribe are met by the proposed ISAT forest management strategy, 2) validate the scientific soundness of the proposed strategy, 3) identify any gaps in the strategy or components not adequately addressed, and 4) make recommendations to correct deficiencies or to make improvements in the strategy. In response to the Tribe's request, the Governor's Office of Natural Resources assembled a team of independent peer reviewers and structured the process by which the review would be accomplished. The results of the IPR were presented to the ISAT in a conference open to the public which was held on November 21, 1995 at the LaSells Stewart Center, Oregon State University. Following is a consolidated report of major conclusions and recommendations presented by the independent reviewers to the ISAT at the November 21 public forum.

Predictive transport analysis of JET and AUG hybrid scenarios
No full textHybrid scenarios in present machines are characterized by improved confinement compared to the IPB98(y,2) empirical scaling law expectations. A number of possibilities explaining this improvement have been proposed: reduction in deleterious MHD, pedestal confinement improvement, rotational shear turbulence suppression, increased turbulent thresholds due to qprofile shaping, and stiffness reduction at low magnetic shear [1, 2, 3]. This work concentrates on isolating the impact of increased s/q at outer radii (where s is the magnetic shear) on core confinement in low-triangularity JET and ASDEX Upgrade (AUG) experiments. This is carried out by predictive heat and particle transport modelling using the integrated modelling code CRONOS [4] coupled to the GLF23 turbulent transport model [5]. This work aims to validate recent predictions of the ITER hybrid scenario also employing CRONOS/GLF23, where a high level of confinement and resultant fusion power sensitivity to the s/q profile was found [6]

Complete Suppression of Neoclassical Tearing Modes with Current Drive at the Electron Cyclotron Resonance Frequency in ASDEX Upgrade Tokamak
No full textOn learning latent dynamics of the AUG plasma state
No full textIn this work, we demonstrate the utility of state representation learning applied to modeling the time evolution of electron density and temperature profiles at ASDEX-Upgrade (AUG). The proposed model is a deep neural network, which learns to map the high dimensional profile observations to a lower dimensional state. The mapped states, alongside the original profile's corresponding machine parameters, are used to learn a forward model to propagate the state in time. We show that this approach is able to predict AUG discharges using only a selected set of machine parameters. The state is then further conditioned to encode information about the confinement regime, which yields a simple baseline linear classifier, while still retaining the information needed to predict the evolution of profiles. We, then, discuss the potential use cases and limitations of state representation learning algorithms applied to fusion devices.Peer reviewe
