Contrary to the conventional view of infancy as a sensorimotor period without conceptual thought, research over the past 20 years has shown that preverbal infants are capable of at least 3 conceptual functions: forming concepts with which to interpret the world, recall of the past, and engaging in conceptual generalization. Research is described indicating that the 1st concepts tend to be globa...

In previous papers we presented a robot cognitive architecture organized in three computational areas. The subconceptual area is concerned with the processing of data coming from the sensors. In the linguistic area representation and processing are based on a logic-oriented formalism. The conceptual area is intermediate between the subconceptual and the linguistic areas and it is based on the n...

A theoretical framework is presented that distinguishes among three knowledge sources thot form the basis for generative performance. The three knowledge sources, termed conceptual, procedural, and utilizational competence, were implemented as o computational model that derives plans for counting procedures. In a previous analysis, Greeno, Riley, and Gelman (1984) developed a characterization o...

IS literature provides a variety of Data Warehouse development methodologies focussing on technical issues, for instance the automatical generation of Data Warehouse or OLAP schemata from conceptual graphical models or the materialization of views. On the other hand, we can observe a growing influence of conceptual modelling in the move of general IS development which is specifically addressing...

The last decades a large amount of research has been done in the genomics domain which has and is generating terabytes, if not exabytes, of information stored globally in a very fragmented way. Different databases use different ways of storing the same data, resulting in undesired redundancy and restrained information transfer. Adding to this, keeping the existing databases consistent and data ...

Recent e orts in the Conceptual Modelling community have been devoted to properly capturing time-varying information. Various temporally enhanced Entity-Relationship (ER) models have been proposed that are intended to model the temporal aspects of database conceptual schemas. This work gives a logical formalisation of the various properties that characterise and extend di erent temporal ER mode...

The CollageMachine interactive artifact and the interface ecology theoretical framework are being codeveloped, through back and forth loops of reference on multiple levels. The open conceptual space of interface ecology enables the formation of cross-disciplinary connections that range beyond the confines of individual disciplines. CollageMachine has been created in this conceptual framework. I...

Application interoperability and data exchange are desirable goals, but conventional system design practices make these goals difficult to achieve, since they create heterogeneous, incompatible conceptual structures. This conceptual incompatibility increases system development, maintenance and integration workloads unacceptably. Conceptual data independence (CDI) is proposed as a way of overcom...

security as one of the basic human needs has a special place in relaxation, comfort and spiritual needs provision. for this reason, security is always of managers, planners, architects and urban designers' interest. solutions and strategies of security provision have been fundamentally changed following prevailing change of housing architecture patterns from homes to residential complexes ...
