We present a new approach lo learn from relational data based on re-representation of the examples. This approach, called propertybased re-representation is based on a new analysis of the structure of refinement graphs used in ILP and relational learning in general. This analysis allows the characterization of relational examples by a set of multi-relational patterns called properties. Using th...

in this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. distributions of absorption coefficients across the spectrum  are obtained from the hitran2008 database. the full-spectrum k-distribution method is used to deal with the non-gray part of the problem, while the gray radiation calculations are performed using the planck ...

The quality of life can be improved and risk of fractures would be effectively reduced, by the proper initial diagnosis of the osteoporotic abnormality. The identification of low bone mineral density (BMD) or the onset of osteoporosis can be performed by means of detecting the extracted trabecular features from digital hip radiographs. The objective of our study was to apply a gradient based im...

in era of service economy, organizations' success depends significantly on providing quality services. therefore, organizations are in the idea of employing tools such as knowledge management to survive. human activities such as knowledge sharing among organizational members are the foundation of knowledge management in organizations. recent studies have shown that the relational psychological ...

objective(s): as heat, pain is one of the most common clinical symptoms. generally, calcitonin (ct) is prescribed as an analgesic agent for the treatment of pain, especially for the pain caused by osteoporosis or primary and metastatic bone tumor. however, the detailed mechanism remains unknown.materials and methods: in this study, chronic constriction injury (cci) rat model was created, and ho...

Abstract The delineation of ecological red lines (ERLs) is great significance to ensure security and improve the quality environment. However, most current ERL only focuses on natural environment, lacks consideration spatial pattern landscape, there no scientific standard for delineation. From perspective patterns (ESPs), this study proposed an method based gray relational analysis (GRA) minimu...

the main purpose of this study was to investigate factors influencing knowledge sharing among the personnel of agricultural extension and education organization in the iranian ministry of jihad-e agriculture. a survey method was employed for the study, and 110 personnel randomly selected as a sample out of 140 who were busy working in the organization. data was collected through a questionn...

Symbolic execution is a classical program analysis technique, widely used for program testing and bug finding. In this work we generalize symbolic execution to support program analysis for relational properties, namely properties about two programs, or about two executions of a single program on different inputs. We design a relational symbolic execution engine, named RelSym, which supports tes...
