The deformation of arch dam during impoundment is critical to evaluate the safety dam, which influenced by many factors that have different action mechanisms. After monitoring data at stages were comprehensively analyzed, a finite element simulation analysis model can consider real temperature, stress and was set up with help method based on whole process effectively separate single caused wate...

background: preterm birth (ptb) is responsible for 70% of neonatal mortalities. various factors influence the risk of neonatal mortality in different populations. objective: our objective was to evaluate neonatal survival rate of preterm infants, and to define its predictors in iranian population. materials and methods: this retrospective cohort study included all preterm (26-37 weeks) infants ...

In this paper, a new methodology is presented for developing a diagnostic system using waveform signals with limited or with no prior fault information. The key issues studied in this paper are automatic fault detection, optimal feature extraction, optimal feature subset selection, and diagnostic performance assessment. By using this methodology, a diagnostic system can be developed and its per...

Broken rails can cause train delays, trains cancelations and, unfortunately, they are common causes of accidents. This aff ects planning of a resources, budget and organization of railway track maintenance. Planning of railway track maintenance cannot be done without an estimation of number of rails that will be replaced due to the broken rail incidents. There are many factors that infl uence b...

But most of us don’t realize that despite a 36 percent drop in total DOD energy use during 1990–99, chiefly due to force reduction, around $5+ billion of the military budget buys energy. Most of DOD’s five billion gallons of annual petroleum use fuels weapons platforms—land, sea, and air— that are manifestly inefficient. To add a little irony, much of the fuel used by the military is exhausted ...

This paper presents an iterative learning controller using neural network (NN) for the robot trajectory tracking control. Basic control configuration is briefly presented and a new weight-tuning algorithm of NN is proposed with a dead-zone technique. Theoretical proof is given which shows that our modified algorithm guarantees the convergence of NN estimation error in the presence of disturbanc...
