A Provenance Tracking Model for Data Updates [PDF]
, 2012 For data-centric systems, provenance tracking is particularly important when the system is open and decentralised, such as the Web of Linked Data. In this paper, a concise but expressive calculus which models data updates is presented.

Modeling and Querying Multi-dimensional Moving Objects
Journal of Harbin University of Science and Technology, 2022 Motivated by the problem that the existing spatio-temporal data models do not fully represent moving objects, we design a multi-dimensional data model supporting multiple attributes, static and dynamic attributes.

Data‐adaptive additive modeling
Statistics in Medicine, 2018 In this paper, we consider fitting a flexible and interpretable additive regression model in a data‐rich setting. We wish to avoid pre‐specifying the functional form of the conditional association between each covariate and the response, while still retaining interpretability of the fitted functions.

Comparative model accuracy of a data-fitted generalized Aw-Rascle-Zhang model [PDF]
, 2014 The Aw-Rascle-Zhang (ARZ) model can be interpreted as a generalization of the Lighthill-Whitham-Richards (LWR) model, possessing a family of fundamental diagram curves, each of which represents a class of drivers with a different empty road velocity.

Data model for the cartographic representation of toponyms on topographic maps published by the MGI [PDF]
Glasnik Srpskog Geografskog DruštvaAn essential aspect of creating topographic maps involves standardization and data modelling for properly visualised toponyms. The significance of this aspect arises from the fact that maps, aside from representing a graphical depiction of ...
