We report our research activities on density functional theory-based alloy thermodynamics, including method/software developments, the integration of first-principles calculations, CALPHAD modeling, and the automation of phase diagram calculations. Examples to be discussed include phonon dispersions of rhombohedral BiFeO3, the solution to the long-outstanding problem of imaginary phonon frequen...

Focused on the problem that the data query of Marxist theory database requires to be optimized, this paper proposes a database query optimization strategy based on improved ID3 algorithm. It firstly changes the measure of property selection in data set so as to decrease the computational expense and generation time, then adjusts the calculation of information gain to the calculation of residual...

Functional dependencies (FDs) are an integral part of database theory since they are used in integrity enforcement and in database design. Recently, functional dependencies satisfied by XML data (XFDs) have been introduced. In this work approximate functional dependencies that are XFDs approximately satisfied by a considerable part of the XML database are defined and the problem of inferring su...

The DNA promoter sequences domain theory and database have become popular for testing systems that integrate empirical and analytical learning. This note reports a simple change and reinterpretation of the domain theory in terms ofM-of-N concepts, involving no learning, that results in an accuracy of 93.4% on the 106 items of the database. Moreover, an exhaustive search of the space of M-of-N d...

This paper represents the study of various theory based on database model. In this paper a study of various papers is done, and in the reviewed paper graph database and SQL is done. This huge repository of unstructured data has resulted in making the data search and knowledge extraction, a very cumbersome task if one continues using the legacy relational database.

In this paper, we present a database-supported corpus study where we combine automatically obtained linguistic information from a statistical dependency parser, namely the occurrence of a dative argument, with predictions from a theory on the argument structure of German particle verbs with nach. The theory predicts five readings of nach which behave differently with respect to dative licensing...

The paper proposes both a general framework and specific techniques for file and database reverse engineering, i.e. recovering its conceptual schema. The framework relies on a process/product model that matches formal as well as empirical design procedures. Based on the analysis of database design processes, two major phases are defined, namely Data structure extraction and Data structure conce...

In this paper we demonstrate that, ignoring computational constraints, it is possible to release synthetic databases that are useful for accurately answering large classes of queries while preserving differential privacy. Specifically, we give a mechanism that privately releases synthetic data useful for answering a class of queries over a discrete domain with error that grows as a function of ...

L.A Zadeh introduced fuzzy set theory in 1965. Many researchers took interest in the theory and evolved many generalizations of the concept. One of them was the Intuitionistic fuzzy set introduced by K.T.Atanassov in 1986. Since its inception, the literature on IFS Theory and its application has been rapidly amounting by now to several thousands of papers. In this paper, IF approach is being ap...

A physical design methodology for network model databases is dcvclopcd using the theory of separability. In particular, a large subset of practically important access structures provided by network model database systems is shown to have tic property of separability under the usage specification schcmc proposed. The theory of separability was introduced in an carlicr work, in the context of rel...
