This paper describes an intelligent exploratory learning environment based on an architecture that allows students to analyze examples by exploring the reasoning of an expert system that embodies the domain topic knowledge. The domain is that of entity relation diagramming (ERD), a database modeling technique. The system presents the student with a series of English descriptions of database sit...

This paper deals with studies of fixed design, where comparability is feasible either for culture or for time and culture. For the time dimension, studies are divided into cross-sectional and longitudinal, and for the cultural dimension they are divided into monocultural and cross-cultural. Since modern societies are mainly organised into nation-states, cross-cultural studies are carried out mo...

This paper provides a relationship between a geometric structure of a suspended tree and the number of link components of the associated link diagram.

A self-consistent density-functional approach is presented for describing the phase behaviour and interfacial tensions of van der Waals fluids represented by the hard-core Yukawa (HCY), Lennard-Jones (LJ) and square-well (SW) potentials. The excess Helmholtz energy functional is formulated in terms of a modified fundamental measure theory (MFMT) for the shortranged repulsion and a density-gradi...

The entity relationship approach is a widely accepted method for conceptual database design. However, some problems arise if ER modelling is applied to the design of really large databases concerning whole enterprises. There is, e.g., no way to obtain a general view nor to perceive the global context of a detailed enterprise scheme with hundreds of entity and relationship types. Different appro...

background: lower limbs antigravity muscles weakness and decreased functional ability have significant role in falling. the aim of this study was to find the effects of aging on muscle strength and functional ability, determining the range of decreasing strength and functional ability and relationship between them in healthy women. methods: across-section study was performed on 101 healthy wome...

This paper presents a two-dimensional investigation of the phase diagram for global minimizers to a Cahn–Hilliard functional with long-range interactions. Based upon the H−1 gradient flow, we introduce a hybrid numerical method to navigate through the complex energy landscape and access an accurate depiction of the ground state of the functional. We use this method to numerically compute the ph...

When using the conventional segmental superposition method to make bending moment diagram, it is not only complicated calculate, but also easy mistakes. In this paper, discussed how flexibly segment and simplify calculation with examples. At same time, according differential relationship, integral relationship static equilibrium conditions between load shear force, fast accurate pithy formula f...
