this study aims to design the management model and planning of career promotion path in the employees of tehran bank mellat branches. the research method is descriptive and survey that was conducted by correlational and structural equations modeling. the statistical population (n=200) of the study included all employees of twenty branches in tehran's bank mellat who were selected as the sa...

We present the application of computer algebra systems (CAS) to symbolic construction of algebraic equations describing different ordered as well as stochastic magnetic structures. We start with formal and exact, however non-tractable from the numerical point of view, Callen equations. Then, we apply the integral operator method (based on the integral representation of Dirac delta function) and...

A new method for the dynamic analysis of the vertical vehicle-structure interaction is presented. The vehicle and structure systems can be discretized with various types of finite elements and may have any degree of complexity. The equations of both systems are complemented with additional compatibility equations to ensure contact between the vehicles and the structure. The equations of motion ...

A group of parallel algorithms, and their implementation for solving a special class of nonlinear equations, are discussed. The type of sparsity occurring in these problems, which arise in VLSI design, structural engineering, and many other areas, is called a block bordered structure. The explicit method and several implicit methods are described, and the new corrected implicit method for solvi...

iran’s unique attractions and destinations make it of great potentiality for utilising tourism industry. according to statistics of the international and national organization tourism, the situation of tourism in iran is not suitable, which is a sign of an undesired situation in the industry and failing to make use of the existing capabilities and potentials of the country. therefore, this rese...

this paper presents new sensitivity-based methods for detection of structural damage using incomplete noisy modal data. these methods are based on the first-order derivative of modal parameters. changes of natural frequency do not usually provide spatial information on the structural damage. they are also not sensitive to the local damage. in this paper, a new sensitivity function is proposed u...

this paper presents an overview of model updating and particularly its application for updating of frame model. in this article a mathematical model of the frame was produced with finite element method. the frame was subjected to hammer modal testing. then the results of the modal testing were compared with those predicted with the model. this comparison revealed discrepancies between these two...

Hybrid systems, i.e., dynamical systems combining discrete and continuous dynamics, have a complete axiomatization in differential dynamic logic relative to differential equations. Differential invariants are a natural induction principle for proving properties of the remaining differential equations. We study the equational case of differential invariants using a differential operator view. We...
