In the present paper the behavior of an elastically mounted cylinder in low and high mass-damping ratio is investigated. For high mass-damping ratio, a classical wake oscillator model is used. At the first, by neglecting all damping and nonlinear terms of this model, the possibility of using a linear model for determination of the lock-in range and the dominant mode is investigated. Then, w...

In the present study, a model of a large Lithium Polymer (Li-Po) battery for use in the simulation of Hybrid Electric Vehicles (HEVs) is developed. To attain this goal, an Equivalent Circuit (EC) consisting of a series resistor and two RC parallel networks is considered. The accuracy and the response time of the model for use in an HEV simulator are studied. The battery parameters identifica...

heretofore, a vast spectrum of pattern recognition methods has been considered by researchers to design credit scoring models. but what has not been considered enough in these studies is the lack of consideration of the needs of this subject which differentiate it from a simple classification. it is necessary to observe the costs of a wrong classification, because practically the cost of improp...

the role of teachers in the educational context could go beyond simply teaching the subject matter. it is not uncommon for some students to be greatly influenced by certain teachers and even consider them as their role models. an interesting and novel way of inferring the impact a teacher has on the students is through revealing the status of the teacher as perceived by the students. the presen...

During the recent decades, the design and construction of underground spaces into rock salt have been particularly regarded for storing petroleum fluids, natural gas, and compressed air energy, and also for disposing nuclear and chemical wastes. The rock salt hosting such spaces will be subjected to various types of monotonic/cyclic, short-term/long-term stresses during the construction and/or ...

introdouction: oral and dental health is viewed as one of the most important domains of public health, which is of over riding importance among mothers who, with regard to their role in maintaining their health and their children’s health, are considered one of the vulnerable groups. materials and methods: this is a cross-sectional study in which 110 pregnant mothers referring to 15 health trea...
