Statefinder diagnostic is a useful method which can differ one dark energy model from the others. The Statefinder pair {r, s} is algebraically related to the equation of state of dark energy and its first time derivative. We apply in this paper this method to the dilaton dark energy model based on Weyl-Scaled induced gravitational theory. We investigate the effect of the coupling between matter...

Existing turnover models have been developed and tested almost exclusively in Anglo cultures. Thus, there is reason to question whether these models apply to workers elsewhere. We addressed this question using as participants 47 Mexican maquiladora workers. Through interview responses analyzed using a variation of grounded theory-building, we inductively created a model of voluntary turnover wi...

Stephen B Maurer ([email protected]) received his Ph.D. from Princeton in 1972, under A. W. Tucker. He is a mathematics professor at Swarthmore College, where he was also an undergraduate. He is coauthor of Discrete Algorithmic Mathematics, with Anthony Ralston. At one time he chaired the MAA high school contests, and he has written guides for undergraduates on writing mathematics. At par...

car body lightening and crashworthiness are two important objectives of car design. due to their excellent performance, composite materials are extensively used in the car industries. in addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. hat shape energy absorber is used in car’s doors for side impact protection. the aim of these numerical models and exper...
