introduction: until now, many models have been presented for optical study of the human eye. in recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. material and methods: in this article, some of these models are considered. they incl...

One of the most important Limitation General Circulation Models , Large scale are being simulation of climatic variables. So should With Various method are downscaled, The ability to have identified a study area. Choose a suitable GCM model for the study area Very important role In the simulation  parameter (precipitation) is intended for future. In this research of CMIP5 Models Contains BCC-CS...

introduction: today, medical software are used in different aspects of healthcare varying from simple data processing to collection and interpretation of physiological information and education of nurses and physicians. to ensure use of medical software, they must be constantly evaluated based on specific criteria. since there is no organized evaluation system and comprehensive criteria for eva...

Background and objective:Medicine is a combination of health and healingthat includes diagnosis, treatment and prevention of disease and many other aspects of health. Despite the fact that many improvements have been made in medical education, medical schools continue to face many problems in facing the community, patients, doctors And students who are not compatible with the s...

forest ecosystems that have spent a long time to mature, offer important goods and services to humanity. hence, utilization and exploitation of these resources should be based on careful assessment of their ecological value and potential. ecological land evaluation is an approach based on land quality, vulnerability and potential assessment for different acceptable uses drawing upon related mod...

introduction: gallium-67 citrate has been known as a good infection agent in nuclear medicine for decades. in this work the value of 67ga-citrate has been investigated in infected animal models using spect imaging at optimized/standardized conditions. methods: the bacterial (staphylococcus aureus; s.a. and escherichia coli; e.c.) and fungal (candidae albicans; c.a.) species from standard sourc...

One of the problems of the data envelopment analysis traditional models in the multiple form that is the weights corresponding to certain inputs and outputs are considered zero in the calculation of efficiency and this means that not all input and output components are utilized for the evaluation of efficiency, as some are ignored. The above issue causes the efficiency score of the under evalua...
