Data curation with ontology functional dependences
… complexity and size of modern datasets. Functional dependencies have been used in existing cleaning solutions to model syntactic equivalence. They are not able to model semantic equivelence, however. We advance the state of data quality constraints by defining, discovering, and cleaning …

A two-dimensional transfer model
… of military truck transport supply and the functional dependencies of the terms in the transfer equations are evaluated. For this interpretation the density equations are given and the study state and time dependent solutions of the density equations are discussed in polar coordinates. This …

Causal structure of networks of stochastic processes
… media sites. We study the statistical and functional dependencies in network of processes. Statistical dependencies can be encoded by directed information graphs (DIGs) and functional relationships using functional dependency graphs (FDGs), both of which are graphical models where nodes …

Design Foundations of Graph Databases
… this end, we introduce redundancy-causing graph functional dependencies that are transformed into graph uniqueness constraints that avoid redundancy. These dependencies strike a great balance between expressiveness and tractability as required for a normalisation framework. Despite the major …

New Approaches to Synthetic Tabular Data Generation
… numerous variables, diverse attribute types, functional dependencies across columns, and temporal dependencies across rows. We aim to explore how to generate higher-quality synthetic tabular data through the following subproblems: (1) auto-regressive DNNs for synthetic table generation (STG), …

Data profiling - efficient discovery of dependencies
… more complex structures, in particular inclusion dependencies (INDs), unique column combinations (UCCs), and functional dependencies (FDs). If present, these statistics and structures serve to efficiently store, query, change, and understand the data. Most datasets, however, do not provide their …

A Design Methodology for A Universal Relation Scheme Implementation via Codasyl
… in the network database (thereby enforcing all functional dependencies embodied in the relational schema). The resulting network schema handles incomplete information, since we use only the modified foreign-key constraint and not the universal instance assumption. The representative instance, a …

Width functions for hypertree decompositions
… invariant directly for structures and exploiting functional dependencies.

Fundamentals and applications of order dependencies
… efficiently when the query optimizer uses order dependencies. They can be run even faster when the optimizer can also reason over known ODs to infer new ones. Order dependencies can be declared as integrity constraints, and they can be detected automatically for many types of SQL functions and …

Transcriptional and Multi-Omic Heterogeneity in Glioblastoma Stem Cells
… have to target this population. Evidence of functional heterogeneity of GSCs at the level of the transcriptome and drug response motivates a full characterization of GSCs’ biological variation. In this project, I use multiple -omic data types from both bulk and single cell resolution to …

Approaches to analyse and interpret biological profile data
… a molecular network model. Since it includes functional dependencies it is termed functional network. Applied to the cold stress data, it is shown that functional networks are appropriate to visualise biological processes and thereby reveals molecular dynamics.

Applications of nonlinear dynamics to information processing
… of the network and what are the potential functional dependencies between the parameters. The class of one-dimensional cellular automata whose state is a function of both the previous state and a time-dependant input is described. As inputs we considered the sequences of binary strings that …

An interdisciplinary study of cathodic debonding in elastomer/metal adhesive bonds
… the empirical model which draws heavily on the functional dependencies of debond rates on the accelerating parameters, i.e., temperature, stress, and applied voltage. An Arrhenius relationship is shown to model the effect of temperature very well. Also, voltage effect is correlated with the …
