s – Data warehouse contains vast amount of data to support complex queries of various Decision Support Systems(DSSs). It needs to store materialized views of data, which must be available consistently and instantaneously. Using a frame metadata model, this paper presents an architecture of a universal data warehousing with different data models. The frame metadata model represents the metadata ...

Preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. If the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. Regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have b...

Energy consumption by distribution warehouses has become an essential component of green warehousing and research on reducing the carbon footprint supply chains. in is a complex multilayered problem, which generally considered literature relation to its detailed components, not as part comparative studies. In this article, authors consider six cross-sectional variants warehouse technology, from...

this paper identifies effective criteria in locating urban parks land use in district 9 of mashhad. this recognition is in three scale of neighborhood, local and regional with emphasis on the principles of minimum distance.finally, surveying the potential of district 9 to build these kind of parks is the main purpose. therefore, by using document anf field research method ,first we survey the l...

Introduction There are many heterogeneities among preexisting informations sources, such as DataBases (DBs), particularly semantic heterogeneities (see our chapter “Semantic Heterogeneity” in [1]). Any secure Federated Information Systems (FIS) must solve them, and deal with a): how schema levels are related to security, and b): operations on schemas to convert from level to level. We present t...

This paper presents architecture for health care data warehouse specific to cancer diseases which could be used by executive managers, doctors, physicians and other health professionals to support the healthcare process. The data today existing in multi sources with different formats makes it necessary to have some techniques for data integration. Executive managers need access to Information s...

We study geodesically complete and locally compact Hadamard spaces X whose Tits boundary is a connected irreducible spherical building. We show that X is symmetric iff complete geodesics in X do not branch and a Euclidean building otherwise. Furthermore, every boundary equivalence (cone topology homeomorphism preserving the Tits metric) between two such spaces is induced by a homothety. As an a...
