anchusa )boraginaceae( includes weedy species in different habitats and cultivations and is composed of four species in iran. species delimitation is mainly based on features as zygomorphic or actinomorphic flowers, straight corolla tube and nutlet shape. in this project, morphological features of different accessions of anchusa species were evaluated. totally, 33 qualitative and quantitative m...

this study contains the identification of modal dynamic properties of a 3-story large-scale steel test frame structure through shaking table measurements. shaking table test is carried out to estimate the modal properties of the test frame such as natural frequencies, damping ratios and mode shapes. among many different model structures, arx (auto recursive exogenous) model structure is used fo...

In this article we present a new method for automatic landmark extraction from the contours of biological specimens. Our ultimate goal is to enable automatic identification of biological specimens in photographs and drawings held in a database. We propose to use Active Appearance Models for visual indexing of both photographs and drawings. Automatic landmark extraction will assist us in buildin...

This paper introduces the smooth operators for arithmetic expressions as an approach to smoothening the search space in Genetic Programming (GP). Smooth operator GP interpolates between arithmetic operators such as ∗ and /, thereby allowing a gradual adaptation to the problem. The suggested approach is compared to traditional GP on a system identification problem.

background: forensic odontology plays important role in identification of human remains in mass disasters such as air crash, tsunami, and accidents. palatal rugae act as an ideal requisite for human identification as they are present in all victims and are resistant to changes such as aging and trauma. the study aimed to analyze differences in shape and number of palatal rugae in population fro...
