Measurement the effects of temperature and fiber orientation on vibration of functionally graded beam

This paper concerned with analytical approach to study the thermal vibration of fiber orientation functionally graded (FOFG) beam, that fibers`oriented angles are variable and graded in the thickness direction of the beam. Uniform thermal distribution considered in the entire beam and properties of fiber orientation functionally graded (FOFG) beam considered as the temperature-dependent element. Symmetrical, asymmetrical, and classical distribution types for the mode of fiber angle presented in the thickness direction of the beam continuously. Equilibrium Equations derived from first- order shear deformation theory and Hamilton principle. Simply supported boundary condition is considered for both edges of the beam.Eneralized differential quadrature method usedto solve the system of coupled differential Equations. To study accuracy of the present analysis, a compression carried out with a known data. The results shows that different parameters such as thickness to radius ratio, effect of temperature variations, model of fibers angle variations and power-law index affected on the natural frequencies

Evaluation of Effectiveness of Implementing Quality Management System (ISO9001:2000) Using BSC Approach in NIGC

The purpose of this research is to evaluate the effectiveness of implementation Quality Management System (ISO 9001:2000) in gas processing plants of National Iranian Gas Company using balanced scorecard approach. More specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in National Iranian Gas Company from four different perspectives in order to provide a more comprehensive view of organizational performance after the registration of ISO 9001. The methodology used in this research comprised administering a questionnaire to 360 respondents in the company in order to find out the results of using ISO 9001:2000 on the firms under study based on four BSC aspects and. The results indicated that: First, the BSC could be used successfully to measure the performance of quality systems in the gas processing plants of NIGC. Second, the findings indicated ranking of five plants based on the BSC perspective. However, the customer and learning perspectives are neglected in the target companies
