Extending the current “2.5D” terrain model is a necessary development in GIS. Existing 2D surface information must be extended to 3D, while trying to preserve the topological integrity. Computer-Aided Design (CAD) on the other hand is often fully 3D, which may be excessive for our “extended 2D” mapping needs. We have used the “boundary representation” (brep) design from CAD systems, based on ma...

The generation of regular and irregular past tense verbs has been an important issue in cognitive science and has been used to advance different models of the organization of language in the brain. The dual-system view holds that the regular past tense forms are generated by a rule while irregular forms are retrieved from memory. The single-system view, on the other hand, holds that both forms ...

We propose a novel approach to self-regenerating systems which require continuous operation, such as security surveillance. For that aim we introduce HADES, a self-regenerating cooperative multi-agent system with local monitoring. When agents of HADES find local failures they repair them. However, in extreme cases repair may not be possible and irregular aggressive agents will multiply. These i...

Neuropsychological dissociations between regular and irregular English past-tense morphology have been reported using a lexical decision task in which past-tense primes immediately precede present-tense targets. We present N400 event-related potential data from healthy participants using the same design. Both regular and irregular past-tense forms primed corresponding present-tense forms, but w...

A connected graph G is said to be neighbourly irregular graph if no two adjacent vertices of G have same degree. In this paper we obtain neighbourly irregular derived graphs such as semitotal-point graph, k^{tℎ} semitotal-point graph, semitotal-line graph, paraline graph, quasi-total graph and quasivertex-total graph and also neighbourly irregular of some graph products.

Point-of-Interest (POI) data are location enriched word data, which consist of personal names, place names including administrative districts, and names of business and recreational locations. They are essential to the development of applications such as Telematics, wireless location-based services (LBS), and tourism and other business applications. Being a major component of Text-to-Speech (TT...
