Distance based heterogeneous volume modelling.
… several approaches to modelling attributes, but distance functions have gained popularity for heterogeneous object modelling because, in addition to their usefulness, they lead to predictability and intuitiveness. In this thesis, we consider a unified framework for heterogeneous volume modelling, …

Distance based vehicle insurance : actuarial and planning issues
Distance based vehicle insurance (sometimes know as “Pay as you drive,” “Pay by the mile” or “Pay per-km” insurance) has long been advocated by transportation planners as a transportation demand management (TDM) strategy. In addition to reducing congestion and greenhouse gas emissions, it also has …

Low dimensional visualization and modelling of data using distance-based models
… in machine learning, namely, the choice of a distance function to describe the similarity of two data points. Often, implicit choices are made, e.g., a spatial scale is chosen to compare images, or features are weighted in a certain way. Unfortunately, different distance functions can yield …

Exploratory Study of Fuzzy Clustering and Set-Distance Based Validation Indexes
… cluster validation is examined and new set distance based cluster validation indexes(CVI) are proposed which are the ratio of separation between clusters to compactness within acluster. To this end, a new measure of compactness, compactness of a fuzzy partition is presentedand fuzzy …

Three-Dimensional Distance Based Geostatistical Models to Adjust Radar Rainfall Data
… on the development of three-dimensional (3D) distances based geostatistical models, such as Regression Kriging (RK) and Merging methods, to perform the adjustments of radar rainfall data to the targeted gauge measurements. These models are tested at the Chenyulan River watershed using the …

Non-Metric Multi-Dimensional Scaling for Distance-Based Privacy-Preserving Data Mining
… method for data perturbation in the context of distance-based data mining. We propose the use of non-metric multi-dimensional scaling (MDS) as a suitable technique to perturb data that are intended for distance-based data mining. The basic premise of this approach is to transform the original …

Efficient facial animation integrating Euclidean and geodesic distance-based algorithms into radial basis function interpolation.
… covering a review of Euclidean and geodesic distance-based algorithms, and proposing a hybrid approach that tries to take the advantages of the two previous methods aided by pre-processed distance data to fasten the computations. Using motion capture performance based on the Facial Action …

Assessment and Strategic Planning to Determine the Growth Feasibility of a Distance-Based Rural Baccalaureate Nursing Program
… between a rural regional campus and a university based college of nursing has extended access to baccalaureate education to those based in that rural area. The purpose of this work sought to assess the feasibility of expanding the current distance-based rural BSN program from a systems level. </p> …

Comparing Distance-Based Vs. Time-Based Exercise Prescriptions Of Walking And Running For Improvement Of Cardiovascular Disease Risk Factors
… Some research has suggested that walking for distance as opposed to walking for time may be a stronger predictor of overall amount of accumulated exercise or physical activity (Williams, 2012a). To our knowledge, research has not been conducted directly comparing a distance-based versus …

A Distance-Based Clustering Framework for Categorical Time Series: A Case Study in Episodes of Care Healthcare Delivery System
… k-medoids clustering as it accommodates string-based distance measures commonly used by categorical sequences while meeting the expectations of physicians that the method returns an existing pathway as the central point and produces clusters of pathways that are edge-connected. Additionally, the …

Some Model-Based and Distance-Based Clustering Methods for Characterization of Regional Ecological Stressor-Response Patterns and Regional Environmental Quality Trends
… in regression relationships, we use model-based clustering procedures with class-specific regression models. Units for clustering are taken to be basins, or combinations of basins and ecoregions. We rely on a Bayesian formulation and sample the posterior distribution using a Markov chain …

Design and Evaluation of Urban Congestion Pricing Policies with Microsimulation of Passenger and Freight
… operations. Finally, we design and evaluate distance-based, cordon-based, and area-based congestion pricing policies for an auto-innovative prototype city. All policies improve total social welfare. The improvement is the greatest under the distance-based policy and the area-based one follows …

Rationality or irrationality of preferences? A quantitative test of intransitive decision heuristics
… I use two types of probabilistic specifications: distance-based models (which assume deterministic preferences and probabilistic response processes), and mixture models (which assume probabilistic preferences and deterministic response processes). I test 26 such probabilistic models on datasets …

Mahalanobis kernel-based support vector data description for detection of large shifts in mean vector
… that SPC offers. Creation of the K chart is based on Support Vector Data Description (SVDD), a popular data classifier method inspired by Support Vector Machine (SVM). As any methods associated with SVM, SVDD benefits from a wide variety of choices of kernel, which determines the …

Node localization in underwater sensor networks (UWSN)
… two localization methods: rotation matrix (RM)-based method and the distance-based method. Both methods require only two anchor nodes with arbitrarily oriented tri-directional coils to locate one sensor node in the 3-D space, thus having advantages in a sparse network. Simulation studies show …
