Data-adaptive reduction of process-based models
Process-based models of environmental systems typically are very complex structures. This complexity arises from the attempt to describe the manifold natural processes and intricate biological interactions of environmental systems in mathematical terms. Because of their high number of state …

Large-scale Process-based Urban Hydrological Modeling Framework
… challenges by introducing a novel, physically-based urban modeling framework designed to simulate urban runoff generation and routing across natural and urban surface areas and through BUSNs. Our framework's innovative design ensures a balanced representation of natural and urban components and …

From Representative Period Selection to Process‐Based Sediment Dynamics
… understood. This thesis develops an integrated, process-based modelling framework to address these gaps. A high-resolution Delft3D-4 model of the NFWS was developed and validated to resolve coupled hydrodynamics and sediment transport. To reduce computational cost, a wind-based method was …

Process-based diagnosis: An approach to understanding novel failures
… systems. Previous approaches in model-based diagnosis have traditionally suffered from either a dependence on explicit fault models or a tendency to produce unintuitive results. This research aims at achieving the explanatory power of explicit fault models, without sacrificing the …

Evaluating a Process-Based Mitigation Wetland Water Budget Model
… and FAO-56 Penman-Monteith (IPM-FAO). A second process-based model, utilizing MODFLOW-2005, was constructed to better predict water levels in mitigation wetlands. Modeled processes included groundwater movement and vegetative resistance to flow, which can be a significant factor in wetland water …

A framework for improving the implementation of process based change
… with implementation of business proves-based change. There is much evidence, both theoretical and empirical, to suggest that there are a high percentage of Information Systems and Business Process implementation failures (Meredith 1981, Lucas 1981, Walsham 1993, Land et al 1989). The aim …

Point process based high frequency volatility estimation : theory and applications
… three main studies with the common theme: point process based high-frequency volatility estimation. The first chapter introduces a new class of high-frequency volatility estimators and examines its asymptotic properties. The second chapter studies the relative importance of market microstructure …

Developing teleonics as a process-based systems method for psychological practice
… 1991). Teleonics is a developing ecology of process-based systems ideas, where process is foregrounded relative to structure. From a teleonics perspective, structure and process are viewed as inextricably linked, while the foregrounding of process is viewed as having significant implications …

Statistical and process-based models for understanding species distributions in changing environments
… species (biotic factors), migratory or dispersal processes (site accessibility) as well as the continuing effects of past events, e.g. disturbances (site legacy). Existing approaches to predict species distributions either (i) correlate observed species occurrences with environmental variables …

Personalized Gaussian process-based machine learning models for forecasting Alzheimer's Disease progression
… of AD diagnosis. To do this, we employ Gaussian Process (GP) Regression as a modeling framework. Using this framework, we design and implement two novel methods for personalized prediction of key cognitive metrics associated with the AD progression (e.g., ADAS-Cog13). Our experimental evaluations …

Process based cost modeling of emerging optoelectronic interconnects : implications for material platform choice
Continuously increasing demand for processing power, storage capacity, and I/O capacity in personal computing, data network, and display interface suggests that optical interconnects may soon supplant copper not only for long distance telecommunication but also for short reach connection needs. In …

Managing Development Organisations: A Process-Based Assessment of Australian Based Non Governmental Development Organisations
This study focused on Australian-based non-governmental development organisations (NGDOs) (also referred to as non-governmental aid agencies). The study used a telephone survey of eleven agencies and a mail survey of forty-five agencies to make inferences about organisational processes of …

A Process-Based Nutrient Model for the Bedded Manure Pack of Confined Beef Systems
… objective of this research was to develop a process-based model that predicts concentration and gaseous emission from the bedded manure pack of a confined beef cattle system, with respect to different bedding material, manure storage time, and ambient temperature. The model incorporated the …

Compartmental Process-based Model for Estimating Ammonia Emission from Stored Scraped Liquid Dairy Manure
The biogeochemical processes responsible for production and emission of ammonia from stored liquid dairy manure are governed by environmental factors (e.g. manure temperature, moisture) and manure characteristics (e.g. total ammoniacal nitrogen concentration, pH). These environmental factors and …

Predicting Sediment Detachment and Channel Scour in the Process-Based Planning Model ANSWERS-2000
… watersheds. The new detachment equations are based on process-oriented equations developed for the WEPP model and they can be applied to ungaged watersheds with a wide variety of soils and land use conditions. The new model (ANSWERS-2000) was evaluated on three watersheds and its predictions …

Towards a process-based understanding of resilience: an investigation into post-trauma resilience in Eritrean refugees
… resilience as an interactional and transactional process or adopts a culturally-sensitive perspective. This study therefore sets out to consider some of these gaps by qualitatively investigating the processes underlying resilience from an ecological, developmental and culturally-sensitive …
