This study examines the feasibility of designing high-speed ships with hull-form geometry suitable for planked construction, with the aim of reducing the hull construction cost. An algorithm is developed for placing prismatic planks on to a three-dimensional hull form to represent a planked construction. A number of well-known hull forms are examined using the algorithm developed in order to as...

A new approach, to measure normalization completeness for conceptual model, is introduced using quantitative fuzzy functionality in this paper. We measure the normalization completeness of the conceptual model in two steps. In the first step, different normalization techniques are analyzed up to Boyce Codd Normal Form (BCNF) to find the current normal form of the relation. In the second step, f...

Understanding conceptual change is an important problem in modeling human cognition and in making integrated AI systems that can learn autonomously. This paper describes a model of explanation-based conceptual change, integrating sketch understanding, analogical processing, qualitative models, truth-maintenance, and heuristic-based reasoning within the Companions cognitive architecture. Sketch ...

The issue in conceptual design theory is to understand the processes which lead to innovation and to create tools which generate step changes in function in an orderly and repetitious manner. Detailed form-function synthesis methods which generally follow the conceptual phase of the design process require input specifications. An extension of function logic is proposed as a means to systematica...

A 3-level schema architecture is proposed to address some inadequacies in recent object-oriented data models. The conceptual schema is based on a normal form object-oriented entityrelationship IOOER) diagram. A set of mapping rules is defined that allows 00 externalschemas, based on the 02 data model, to be generated from the conceptual schema. Similar mapping rules can be defined to generate e...

Although it is generally accepted that patients with amnestic mild cognitive impairment (aMCI) and patients with Alzheimer's disease (AD) have significantly impaired recollection, recent evidence has been mixed as to whether these patients demonstrate impaired memorial familiarity. Recent work suggests that familiarity may remain intact for pictures, but not for words. Further, a recent event-r...

Human thought and language rely on the brain's ability to combine conceptual information. This fundamental process supports the construction of complex concepts from basic constituents. For example, both "jacket" and "plaid" can be represented as individual concepts, but they can also be integrated to form the more complex representation "plaid jacket." Although this process is central to the e...

All the specialists have agreed that the possibility of adding to multimedia WWW objects some sort of ‘conceptual’ annotations describing their information content would greatly contribute to solve the problem of their ‘intelligent’ indexing and retrieval. We propose to associate with the Web objects not the final conceptual annotation, but a simple natural language (NL) caption, in the form of...

For succesful information systems development, conceptual data modelling is essential. Nowadays many techniques for conceptual data modelling exist, examples are NIAM, FORM, PSM, many (E)ER variants, IFO, and FDM. In-depth comparisons of concepts of these techniques is very diicult as the mathematical formalisations of these techniques, if existing at all, are very diierent. As such there is a ...
