The data were collected by means of questionnaire. 2400 residents of Tehran were selected by stratified sampling who were over 15 years old. The theories of scholars such as Pierre Bourdieu, James Coleman, and Robert Putnam in definition of social capital are applied. Social capital has been studied in five aspects including associ...

One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...

  Background: Recently, quality is a serious concern in development of organizations. There are various indicators to assess quality and the purpose of this study was to identify the main indicators for quality measurement of Iranian health centers.   Methods : This qualitative study was conducted in three stages: first, review of the literature was performed to identify different indicators fo...

It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. These indices have been widely used in the manufacturing industry for measuring process reproduction capability according to manufacturing specifications. In the past few years, univariate capability indices have been introduced and used to characte...

In this paper satellite wave propagation at Ku and Ka band is considered. The design and simulation of a typical satellite beacon receiver at Ka band is designed and simulated for the future works. Also rain attenuation prediction at Ku band using satellite signal beacon measurement and simulations for Iran Telecommunication Research Center (ITRC) are presented. The measurement setup consists o...
