The appearance of Square in Northwest Iran, as a traditional element of the city, did not have a certain definition in the urban planning due to its structural disruption in the spatial fabric as well as its chaotic present in the manifestation of its identity. On the other hand, since the concept of the square in this area does not match to the similar models existing in the central plateau of...

The main issues of spatial databases and Geographic Information System (GIS), concern the representation, the management and the manipulation of a large and complex number of spatial objects and spatial relationships. In these systems many concepts are spatial and, therefore they are intrinsically related with a visual representation, which makes also easier to formulate queries by non-expert u...

It is unknown whether lifestyle, including mental stimulation, and appropriate training interventions, may directly improve spatial navigation performance and its underlying neural substrates. Here we report that healthy younger and older men performing a cognitively demanding spatial navigation task every other day over 4 months display navigation-related gains in performance and stable hippoc...

We examined the functional role of white matter growth in cognitive development. Specifically, we used hierarchical regression analyses to test the unique contributions of age versus white matter integrity in accounting for the development of information processing speed. Diffusion tensor imaging was acquired for 17 children and adolescents (age range 6-17 years), with apparent diffusion coeffi...

In the geographical database context, the UML profile called GeoProfile is used in the conceptual modeling of geographical data with welldefined metamodel topology constraints through the use of Object Constraint Language (OCL). This paper describes the process of automatic transformation of GeoProfile constructors and its spatial constraints along the different levels of the MDA architecture. ...

Welcome to the Signal Integrity and Power Column!

Traditional methods of assessing the geometric integrity of any nely engineered product requires the use of xtures. The t is then tested with a feeler gauge. Fixtures are expensive to construct and transport and the degree of accuracy obtained may be insu cient, depending on the tolerance speci ed by the procurer of the part. In this paper, we discuss an alternative scienti c approach to assess...

Geo-ontologies have a key role to play in the development of the geospatial-semantic web, with regard to facilitating the search for geographical information and resources. They normally hold large amounts of geographic information and undergo a continuous process of revision and update. Hence, means of ensuring their integrity are crucial and needed to allow them to serve their purpose. This p...
