in this paper, a crack localization method for euler-bernoulli beams via an efficient static data based indicator is proposed. the crack in beams is simulated here using a triangular variation in the stiffness. static responses of a beam are obtained by the finite element modeling. in order to reduce the computational cost of damage detection method, the beam deflection is fitted through a poly...

this survey is conducted with the purpose of studying factors effective in vitality of residential complexes. this is an important subject because through recognition of the reciprocal relation between human being and environment -as far as vitality is concerned- various attitudes and approaches can be recognized and on the other hand, for the purpose of explaining the concept of vitality in th...

background: an obvious gradient in health outcomes has been implicated in many evidences relating to social and economic factors. proper data are requested to convince policy-makers calling for intersectoral action for health. recently, i.r. of iran has come up with 52 health equity indicators to monitor health equity through the country. conducting regular surveys on 14 out of 52 national heal...

biogeochemistry is a useful tool for assessing geochemical dispersion patterns. sari gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern iran. in this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized vein. a sample from each dominant plant ...

Sequential Gaussian simulation (sgsim) and sequential indicator simulation (sisim) have emerged as powerful tools for stochastic imaging of Earth Science phenomena and are currently widely accepted fast simulation algorithms. In this paper, we will expand the sequential simulation toolbox by relying on a recent development in geostatistical theory (Journel, 1994) denoted as direct sequential si...

We present a method for calculating the boundary of objects from Discrete Indicator Functions that store 2material volume fractions with a high degree of accuracy. Although Marching Cubes and its derivatives are effective methods for calculating contours of functions sampled over discrete grids, these methods perform poorly when contouring non-smooth functions such as Discrete Indicator Functio...

We read with interest the paper in the May issue on the theme of performance indicator scoring by Houghton and Rouse.1 We were surprised that they did not refer to a conceptually similar attempt we made to develop a composite performance indicator — the National Health Service Practice Performance Index (NHSPPI) — in three areas of England (including their own) and one in Scotland.2 As Houghton...
