The field and laboratory evidence of nonlinear soil behaviour, even at small strains, emphasizes the importance employing methods in seismic ground response analysis. Additionally, determination dynamic characteristics layers always includes some degree uncertainty. Most previous stochastic studies analysis have focused only on variability parameters, effect sample location has been mostly igno...

drug therapy is a complex and important process and because of the importance of drug interactions, especially in in-patients, accompanying problems and obstacles would exist as a result of concomitant use of drugs in these patients. for this purpose 3130 prescription order forms from bou-ali hospital were collected and all potential drug interactions presentwere extracted and evaluated in term...

A new retrofit targeting procedure, based on pinch technology has been developed. The new procedure considers existing structure of a given network and finds the most compatible configuration with the network. To achieve this aim, the procedure uses a linear programming technique that maximize the compatibility. Good compatibility between old and new networks helps to make the best use of c...

The buildings are usually divided into two categories in light of whether obstacles exist: the large space with no obstacles (C-type buildings) and the complex buildings with lots of obstacles (L-type buildings). In this paper, considering the aisle region attraction factor, we proposed a revised model which is suitable to simulate the evacuation process in the L-type buildings (such as classro...

This paper describes a mobile robot navigation method in dynamic environments. The method uses a real-time omnidirectional stereo which can obtainpanoramic range information of 360 degrees. From this panoramic range information, the robotfirst estimates its ego-motion b.v comparing the current and the previous observations in order to integrate observations obtained at different positions. The ...
