abstract in the third millennium, knowledge management was introduced as a strategic need for educational institutions and higher education systeme. in fact, relying on human capital, ideas and information, will ensure long term excellence of the organizations and communities. nowadays, it has been possible to enhance higher education and research capabilities and skills through wise utilizati...

In this paper, condition monitoring of a geared rotor system using finite element (FE) model updating and particle swarm optimization (PSO) method is onsidered. For this purpose, employing experimental data from the geared rotor system, an updated FE model is obtained. The geared rotor system under study consists of two shafts, four bearings, and two gears. To get the experimental data,  iezoel...

Background: Health technology assessment (HTA) is a tool utilized for efficient dissemination of technology. For the purpose of encouraging decision-makers to utilize this tool, at first, we need to identify the obstacles in the processes of preparation, utilization, and implementation of HTAs. This study aims to define these barriers and offer solutions for effective utilization of HTA reports...

Possibility theory is applied to the updating problem in a knowledge base that describes the state of an evolving system. The system evolution is described by a possibilistic Markov chain whose agreement with the axioms of updating is examined. Then it is explained how to recover a possibilistic Markov chain from a set of transition constraints, on the basis of a specificity ordering.

BACKGROUND AND AIM: Poor oral health is known as a risk factor for adverse pregnancy outcomes such as low birth weight (LBW) and preterm birth. Few studies have evaluated the knowledge and behaviors of healthcare professionals about oral health during pregnancy and the possible role of periodontal diseases in adverse pregnancy outcomes. The present study aimed ...

In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...
