In this work we use of an optimized homotropic transformation structural element in order to improve the preprocessing stage for handwriting and hand printed document analysis. The homotropic transformation is use to improve the sequential thinning procedure. In that case we produce less coarse skeleton lines with a reduced number of thinning cycles. If the documents are not good enough, an ada...

Results from bi-directional tests are not the same as those obtained from top loading tests and although bi-directional test data often contain more geotechnical information, it is the characteristic behaviour of the head of the pile which is of interest. In order to provide an equivalent top loading characteristic, methods have been developed to enable the addition of the individual components...

In the last few years, the graphics processor units (GPUs) have moved away from the traditional fixed-function 3D graphics pipeline toward a flexible general-purpose computational engine. Moreover they are getting cheaper and more powerful [1]. The GPU is especially well-suited to address problems that can be expressed as data-parallel computations i.e. the same program is executed on many data...

We calculate elastic moduli and viscosities for media containing strongly interacting in-plane shear cracks. The cracks are randomly oriented or aligned, with equal length or a logarithmic size distribution. Our results from both a boundary element and a finite-element method suggest that the average moduli are best approximated by a differential, self-consistent model (DEM). Thus crack-tocrack...

The impetus behind this s‌tudy is to discover the aes‌thetic and semantic patterns of the cypress tree and show how this element has been employed by Iranian artis‌ts. The ques‌tion of this research is how a cons‌tant element (the cypress tree) has been transfigured in different Iranian arts. Four categories of miniature, carpet, textile and architecture decoration. The present research is qual...

Data Quality has many dimensions one of which is accuracy. Accuracy is usually compromised by errors accidentally or intensionally introduced in a database system. These errors result in inconsistent, incomplete, or erroneous data elements. For example, a small variation in the representation of a data object, produces a unique instantiation of the object being represented. In order to improve ...

As data sources and data size proliferate, knowledge discovery from ‘Big Data’ is starting to pose several challenges. In this paper, we address a specific challenge in the practice of enterprise knowledge management while extracting actionable nuggets from diverse data sources of seemingly related information. In particular, we address the challenge of archiving knowledge gained through collab...
