HYDROGEOLOGICAL CHARACTERIZATION OF A LEGACY WASTE STORAGE SITE AND THE CHALLENGE OF COMMUNICATING UNCERTAINTY
… the rate and distance contaminants travel. The inherent uncertainty of modelling results prompted research into how people interpret and respond to scientific uncertainty. There is a need for the ongoing research into the communication of scientific estimations and depoliticizing scientific …

What causes an organisation to be what it is and to become what it could be: A philosophical expedition
… how a thesis actually happens, with all the inherent uncertainty and messiness. The life experiences of the author are brought to bear in this autoethnographic study of the business world.

classCleaner: A Quantitative Method for Validating Peptide Identification in LC-MS/MS Workflows
… peptide sequence of each measurement, there is inherent uncertainty in the identity of each peptide and its originating protein. Removing misidentified peptides can improve the accuracy and power of downstream analyses when differences between proteins are of primary interest. In this …

Lifted First-Order Probabilistic Inference
… While probabilistic models can deal well with inherent uncertainty in many real-world domains, they operate on a mostly propositional level. Logic systems, on the other hand, can deal with much richer representations, especially first-order ones. In the last two decades, many probabilistic …

Photon Arrival Time Quantum Random Number Generation
… physical process, extracting randomness from the inherent uncertainty in quantum mechanics. This is to be contrasted with current pseudo-random number generators (PRNG), which although useful, are in fact deterministic: they always yield the same output sequence given the same input seed. This is …

Uncertainty and Risk Analysis in Fire Safety Engineering
… has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. The standard QRA does not consider the uncertainties in the variables and must be complemented by a sensitivity analysis or an uncertainty analysis. Both methods provide risk measures, such as …

Development of a Multicriteria Spatial Decision Support System with Application to the Economic Optimization of Aircraft Based Weather Data Collection
… decision support design problems such as inherent uncertainty, required subject-matter knowledge, geo-spatial data dimension, resolution of conflicting goals, reduction of complexity and, qualitative judgment. The developed model has wide application to other weather information and data …

Actor based behavioural simulation as an aid for organisational decision making
… processes, environment where it operates, and inherent characteristics of the change drivers that may impact the organisation. The size of a modern organisation, its socio-technical characteristics, inherent uncertainty, volatile operating environment, and prohibitively high cost of the …

Segmental multi-point linearization for topology optimization and reliability analysis
… be impractical as this formulation ignores the inherent uncertainty and randomness in structural design problems. The objective of RBTO considered in this research is to identify the optimal topology of truss structures with minimum weight which also satisfy certain requirements on the …

Monte Carlo Methods for Motion Planning and Goal Inference
… therefore, be capable of: (1) acknowledging the inherent uncertainty in various obstacle avoidance strategies; and (2) predicting motion plans in a way that recognizes the different possibilities in a given goal-driven navigation scenario. To address these needs, we introduce a framework that …

Leveraging Uncertainty: A Framework for Argumentation in Socioscientific Ill-Structured Problem Solving
… 'fuzzy'. Novice learners struggle with the inherent uncertainty embedded at all stages of the problem-solving process. Students need opportunities to grapple with the challenges of real-world problems, including the inherent uncertainties associated with them. In problem-solving situations …

Sustainable design of complex industrial and energy systems under uncertainty
… various types of industries.</p> <p>Owing to inherent complexity and uncertainty, however, sustainability problems of industrial and energy systems are always very difficult to deal with, which has made industrial practice mostly experience based. For existing research efforts on the study of …

A triage approach to streamline environmental footprinting : a case study for liquid crystal displays
… and lacks harmonized guidance for incorporating uncertainty. Current methods to streamline LCA may amplify uncertainty, undermining robustness. Despite high uncertainty, effective and efficient streamlining approaches may be possible. A methodology is proposed to identify high-impact activities …

Asteroid deflection campaign design integrating epistemic uncertainty
… requires extreme care for decision makers due to inherent uncertainty. The forms of uncertainty can be epistemic or aleatoric. Epistemic uncertainty can be reduced by replenishing incomplete information with better observations, whereas stochastic uncertainty cannot be reduced owing to its …

Balancing exploration and exploitation: task-targeted exploration for scientific decision-making
… and exploitation when making decisions under uncertainty. This thesis argues that efficient decision-making in real-world, scientific domains requires task-targeted exploration—exploration strategies that are tuned to a specific task. By quantifying the change in task performance due to …

From Shipyard to Sea: A Flexible System Design Approach to the Transition from Shipbuilding to Operations A Case Study Using the United States Coast Guard Offshore Patrol Cutter Program
… are driven by three primary factors: the inherent uncertainty in ship construction, sociotechnical system dynamics associated with organizational management of pre-commissioning crews, and the ongoing evolution of technology. To address these challenges, this analysis employs an integrated …

An evaluation of short innovation contest implementation in the federal context
… procurement methods. For this reason, there is inherent uncertainty in the organizational implications contest implementation will have in government agencies which has made program managers hesitant to employ this strategy in their programs. This thesis sheds light on the cost structure, …

On the Ethical Implications of Personal Health Monitoring
… in England is carried out. Recognising that the inherent uncertainty of the future undermines the validity of empirical research, a novel epistemological framework based in Habermas’ discourse ethics is created to justify the empirical study. By developing Habermas’ concept of translation into a …

PetroVis & FractVis: Interactive Visual Exploration of High-dimensional Oil and Gas Data
… data sets due to their high dimensionality, the inherent uncertainty of the data, and the lack of effective visual analytic interactive tools. In this thesis, we attempt to look for new ways to support domain experts in interpreting high dimensional oil and gas data. For the exploration we …
