Bandar Abbas (center of Hormozgan province) is the most important port city in the south of Iran because of its historical places, cultural, economic, social and political importance. High risk of earthquake occurrence in this city and its province indicates the necessity of surveying the seismic vulnerability of buildings. The object of this paper is collected from existing Buildings, compiled...

this study was carried out to investigate the possibility of prediction the occurrence of heat stress in dairy cows and determination of climate critical periods. the most common indexes for estimation the degree of thermal stress istemperature humidity index (thi). in this study yousef’s thi index (1985)was used to analyze the yearly and monthly effects of temperature and humidity. meteorologi...

The determination of the time at which an event may take place in future is a well-studied problem number science and engineering disciplines. Indeed, for more than fifty years, researchers have tried to establish adequate methods characterize behaviour dynamic systems implement predictive decision-making policies. Most these efforts intend model evolution nonlinear terms stochastic processes; ...

To investigate the effects of certain factors on the rate of retained placenta, 2844 calving records from 1288 Holstein cows in a herd were used. These cows calved during year period of 2001 to 2007. A generalized statistical linear model was applied to analyze the data. Logistic regression model was applied as the statistical model. In the model, fixed effects of year, season (warm or cold) an...

Fault Tree Analysis (FTA) as a Probabilistic Risk Assessment (PRA) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. To conduct a quantitative FTA, one needs a fault tree along with failure data of the Basic Events (BEs). Someti...

this study predicts corporate bankruptcy five years before its occurrence using financial ratios introduced in altman’s z-score model and current ratio. three estimation methods namely; liner probability, logit and probit models have chosen for model estimation. the sample contains 134 companies in tehran stock exchange during 2003. the precision of prediction of the estimated models for the ma...
