Screening 0D Materials for 2D Nanoelectronics Applications
As nanoelectronic devices based on 2D materials are moving toward maturity, optimization of the properties of the active 2D material must be accompanied by equal attention to optimizing the properties of and the interfaces to the other materials around ...

Integrating Fuzzy Decisioning Models With Relational Database Constructs [PDF]
Human learning and classification is a nebulous area in computer science. Classic decisioning problems can be solved given enough time and computational power, but discrete algorithms cannot easily solve fuzzy problems. Fuzzy decisioning can resolve more

A Data Integrity Verification Scheme for Centralized Database Using Smart Contract and Game Theory
Currently, many companies and institutions use centralized or distributed databases to store massive amounts of data. However, the use of untrusted centralized third-party auditors can result in security issues because these auditors may be malicious and

Equational theories and database constraints [PDF]
We present a novel way to formulate database dependencies as sentences of first-order logic, using equational statements instead of Horn clauses. Dependency implication is directly reduced to equational implication. Our approach is powerful enough to express functional and inclusion dependencies, which are the most common database constraints.

Theory of sketches for database mappings [PDF]
This paper presents two basic operations, separation and data federation, for database schemas that are used in database mapping systems and explains why functorial semantics for database mappings need a new base category instead of usual Set category.

Foundations of data-aware process analysis: A database theory perspective [PDF]
In this work we survey the research on foundations of data-aware (business) processes that has been carried out in the database theory community. We show that this community has indeed developed over the years a multi-faceted culture of merging data and ...
