Wheel numeric and different versions of mobility numbers are important models for predicting the rolling resistance. In this study, data related to the rolling resistance of cross ply and radial ply tires were compared with the resultant values from several models. Also, the preciseness of models in rolling resistance prediction was evaluated. For this purpose F test and 1-1 line method (p≥ 0.0...

analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. this slender is free to move in both in-line and cross flow directions and immersed completely in water. three different types of shear currents pass on it and cause to vibrate slender in different forms. nowadays, these vibrations are very important for de...

with the growth in customers’ demand diversification, mixed-model u-lines (mmul) have acquired increasing importance in the area of assembly systems. there are generally two different approaches in the literature for balancing such systems. some researchers believe that since the types of models can be very diverse, a balancing approach without simultaneously sequencing of models will not yield...

pishgam was selected from the progeny of a cross between barakat iranian bread wheat cultivar and chinese 90-zhong 87 winter-habit ( bkt/90-zhong 87) in 1995. the f1 generation seeds were planted in karaj station in 1995-96 cropping season. selected-bulk method was applied to segregating generations from f2 to f5 generations for characters such as winter hardiness, plant height, straw strength,...
