This project has three goals. First, we support interoperable query processing among multiple heterogeneous sources. Heterogeneity arises due to the existence of diierent data models, schema and query languages. For an initial query posed w.r.t. a schema and query language, we produce mediated (transformed) queries w.r.t. other schema/query languages. The second goal is to modify traditional qu...

The aim of this paper is to investigate the controversial issue of the nature of the representation constructed by individuals to solve arithmetic word problems. More precisely, we consider the relevance of two different theories: the situation or mental model theory (Johnson-Laird, 1983; Reusser, 1989) and the schema theory (Kintsch & Greeno, 1985; Riley, Greeno, & Heller, 1983). Fourth-grader...

The thesis will study behaviour and uses of fragment schemas in tree-based Genetic Programming (GP). Key contributions will include: new tools for efficient analysis of the propagation of fragment schemas in GP evolution, empirically based conclusions of the validity of the GP Building Block Hypothesis (GP-BBH) with fragment schemas and the accuracy of selected results from GP schema theory, an...

According to cognitive theory, an important factor in borderline personality disorder (BPD) is hypervigilance. The aim of the present study was to test whether BPD patients show schema-related biases, and to explore relations with childhood trauma, schemas, and BPD symptoms. Sixteen BPD patients were compared with 18 patients with a cluster C personality disorder, 16 patients with an axis I dis...

In this paper we present a simple database definition language: that of categories and functors. A database schema is a category and a state is a set-valued functor. We show that morphisms of schemas induce three “data migration functors” that translate states from one schema to the other in canonical ways. Database states form a topos of which the classical “relational algebra” is a fragment. ...

Two main weaknesses of GA and GP schema theorems are that they provide only information on the expected value of the number of instances of a given schema at the next generation Em(H; t + 1)], and they can only give a lower bound for such a quantity. This paper presents new theoretical results on GP and GA schemata which largely overcome these weaknesses. Firstly, unlike previous results which ...

Schema of reductionism on which traditional cost accounting frame relies is not suitable for measuring product cost in the disequilibrium manufacturing process, where “actual time” fluctuates almost beyond control according to parameters. A new schema that is dependable even under such volatile environment could be built by reverting to cash flow and standard value. As there has not appeared a ...

In this paper, the author first analyzed the model and structure of the native XML database (NXD) and studied the application schema and structure of the GML 3.x implementation. Based on these, the author proposed the schema cluster storage and the numerical index technology to store and index GML spatial data, and adopted JavaBean technology to extent the inner module of the eXist-db to prove ...
