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...

Background: The publicchr('39')s understanding of radiation and protection of radiation harm is not high. Therefore, it is meaningful to know the radiation safety literacy level in terms of health care. This study developed a measurement tool that can help to identify the actual condition of radiation safety literacy and conducted the statistical assessment of the developed tool. Materials and ...

We have developed a new system for measuring dental, gnathic, and facial areas with cephalogram-equivalent images created from computed tomographic imaging data. An advantage of this collaborative is that measurement template automated processing are used. First, experienced orthodontists were provided the templates; they then moved markers to specified landmarks on cephalogram in template. Sub...

hyperbilirubinemia is a common problem during neonatal period especially in preterm neonates. transcutaneous bilirubin measurement (tcb) by special devices had been documented as an effective tool for predicting neonatal jaundice in full term neonate, but for preterm infants the present evidences are controversial. we carried out a prospective study in shariati hospital nicu. 126 paired tcb/tot...

this article deals with some social aspects of scientometry. although scientometry and isi -one of the scientometry evaluative standards- are something necessary for scientific measurement, they are not without defects. in this regard, the author argues that there are two significant points among criticism. these points are supposed to be external and internal. the external point is highly affe...
