Cities as the most complex man-made structures have been always exposed to natural and man-made hazards; these unpredictable risks have imposed seriousimpacts on urban areas. Meanwhile Urban Resiliency is the ability of cities to respond quickly to inappropriate and unpredictable conditions, which continiues stronger than before, consistent to the new conditions. Karaj as one of the metropolise...

A crucial component of performing sufficient dimension reduction is to determine the structural dimension of the reduction model. We propose a novel information criterion-based method for this purpose, a special feature of which is that when examining the goodness-of-fit of the current model, one needs to perform model evaluation by using an enlarged candidate model. Although the procedure does...

As opposed to trees that use a single type of decision node, an omnivariate decision tree contains nodes of different types. We propose to use Structural Risk Minimization (SRM) to choose between node types in omnivariate decision tree construction to match the complexity of a node to the complexity of the data reaching that node. In order to apply SRM for model selection, one needs the VC-dime...

The purpose of this paper is to examine the relationship between export barriers and the export performance of Greek firms targeting the Iranian market. Reviewing the literature and using expert opinions, 18 variables were identified. A structured questionnaire was applied to 141 Greek firms and exploratory and confirmatory factor analyses were used to categorize variables in 6 dimensions. Then...

ions that are not shown include:  The multiple dimension systems of the Person object frame class; these typically include: o A special “component holder” dimension system. o A 4D dimension system (a Cartesian coordinate + time system).  Transforms between the above two dimension systems. Some of the descriptions of definitions in the following sections will refer to this diagram. Structural ...

In a multidimensional (MD) database, dimensions may be subject to semantic conditions that are not enforced by MD DBMSs or data warehouse applications. Strictness and homogeneity are possibly two of them; and are crucial for the efficiency and correctness of answering MD aggregate queries and updating materialized aggregate views. Dimensions may become inconsistent, i.e. non-strict or heterogen...
