Exploration vs. exploitation : reducing uncertainty in operational problems
… tradeoff between performing work under uncertainty (exploitation) and investing resources to reduce the uncertainty in the decision making (exploration/testing). Unlike existing models, in which the exploration-exploitation tradeoffs typically relate to learning the underlying …

Approaches to quantifying and reducing uncertainty in GCMs over Southern Africa
… systematic error. Along with other sources of uncertainty regarding our understanding of the climate system and given the quasi-chaotic nature of the climate, climate projections differ between models whose climate simulation skill is poorly quantified. A new methodology is presented to assess …

Conservation by Consensus: Reducing Uncertainty from Methodological Choices in Conservation-based Models
… or threatened), remains an activity filled with uncertainty. Species that are of conservation concern often are found infrequently, in small sample sizes and spatially fragmented distributions, thereby making accurate enumeration difficult and traditional statistical approaches often invalid. For …

Reducing uncertainty: an exploratory study of people's treatment decisions after transient ischaemic attack or minor stroke
… is the person's use of strategies to reduce uncertainty relating to their risk of stroke. I propose that people's primary aim in seeking health care, accessing information, and making treatment choices after TIA or minor stroke, is to reduce their perception of uncertainty about the threat of …

Financial reporting quality and uncertainty about credit risk among the ratings agencies
… whether financial reporting quality resolves uncertainty about credit risk by examining how it affects disagreement between rating agencies. I find better reporting quality is associated with less uncertainty about credit risk as captured by disagreement about ratings between the agencies. …

Probablistic risk analysis of financial investment decisions. A probabilistic analysis of the financial performance of'selected Colombian companies and banks for the period 1973-1977 with application to the investment decision process.
… procedure developed for assessing risk and reducing uncertainty inherent in the investment decision making process. It is proposed that the two most important profitability financial ratios in relation to investment decisions are the return on equity and the return on assets respectively. In …

A literature review into Parents' experiences of raising a child with a disability, and research exploring mothers' experiences of receiving a diagnosis of Monosomy 1P36 deletion syndrome for their child
… Syndrome. An overarching theme of facing uncertainty / reducing uncertainty emerged from the data, and this was connected with five themes: gaining information, being supported / not being supported, being powerless, jumping to the future / living in the here-and-now, and diagnosis making …

Deliberation in Practice: Deliberative Theory, News Media, and Political Conversation
… the common interest, and the accommodation of uncertainty. Results show that American democracy is deliberative in some ways but not in others. Political conversation is disproportionately the pastime of the elite, and discussion across lines of difference, an essential element of deliberation, …

Development of inexpensive hands-on mechanics laboratory exercises for the web and around the world
… sets of hands-on activities, including reducing uncertainty, graphing techniques for clear representation of the functional form of the data, experimental design to minimize systematic errors and comparing different ways of measuring the same physical properties.

Active Multi-View Object Pose Estimation Using a Mobile Ground Robot
… the efficacy of active multi-view collection for reducing uncertainty and lay the foundation for future extensions with automated key point detection and You Only Look Once (YOLO) supported multi object detection.

Organisational ventriloquism in a project centered organization : a qualitative inquiry into the effects of ritualized mimeticisomorphism within a project centered organization
… illuminated that the desire for control, reducing uncertainty and the need for competitiveness serve as social forces towards the adoption of mainstream project and programme management standards and structures. Furthermore, the research explored the consequences of this phenomenon, within …

Integral Quadratic Constraints and Safety Certificates for Uncertainty Characterization and Control Safety-Aware Filtering of Proximity Operations Between Satellites
… capture of unmodeled dynamics to reduce system uncertainty of proximity operations among the Servicer, client satellite (Client), and unsafe regions (e.g., obstacle). The same controller is implemented with a finite time horizon (i.e., model predictive controller) to filter out unsafe control …

Efficient computer experiment designs for Gaussian process surrogates
… experiments for their predictive accuracy and uncertainty quantification. This dissertation addresses GP modeling when data abounds as well as GP adaptive design when simulator expense severely limits the amount of collected data. For data-rich problems, I introduce a localized sparse …

LOST IN INTERPRETATION: THE LIVED EXPERIENCE OF NURSE INTERPRETERS IN THE CLINICAL SETTING
… four main categories: protection of patient, uncertainty, challenges, and RN interpreter effect. The following descriptive summary emerged from this qualitative descriptive study: nurse interpreters may harm the patient-provider interaction by increasing noise, but they protect the patient by …

Modeling the Early Identification and Intervention of Alzheimer’s Disease
… evidence by estimating the societal value of reducing uncertainty surrounding the decision model through further research. Economic evidence about the relative costs and outcomes of health and social care can assist decision makers in determining the best use of scarce healthcare resources.

Probabilistic and Statistical Learning Models for Error Modeling and Uncertainty Quantification
… nature can be attributed to different sources of uncertainty including the parameters of the model, input data, or some missing physics that is not included in the model due to a lack of knowledge or high computational costs. Uncertainty reduction approaches seek to improve the model accuracy by …

Minimizing uncertainty in cure modeling for composites manufacturing
… goals of this work are to identify sources of uncertainty in the decision-making process from cure measurement by differential scanning calorimeter (DSC) to cure kinetics modeling, and to recommend practices for reducing uncertainty. Variability of cure kinetics model predictions based on DSC …

Parameter and topology uncertainty for optimal experimental design
… algorithms for simulation, quantification of uncertainty, and optimal experimental design for reducing uncertainty. We applied a previously described algorithm for choosing optimal experiments for reducing parameter uncertainty as estimated by the Fisher information matrix. We found, using a …
