Background & Aim: Unified Medical Language System (UMLS) is an extensive ontology of biomedical knowledge developed and maintained by U.S. National Library of Medicine (NLM). Traditional Iranian Medicine (TIM) does not have any position in the structure of metathesaurus of UMLS. The main aim of this study was designing a scheme of TIM cluster's crotch mapping in the structure of metathesaurus o...
a filtering power divider/power combiner based on half mode substrate integrated waveguide technology for high power applications is proposed. this design includes one half mode substrate integrated waveguide cavity, one matched load, and four sections of quarter-wavelength transmission lines. the high isolation between output ports is obtained by combining the half mode substrate integrated wa...
This letter presents an eigenfilter approach to obtain the optimal weights of a diversity receiver using maximum ratio combining (MRC). It is shown that the optimal weights correspond to a matched filter solution for stochastic signals and that the optimal weights are the same regardless of the signal branch correlation.
the purpose of this study is identifying effective factors which make customers shop online in iran and investigating the importance of discovered factors in online customers’ decision. in the identifying phase, to discover the factors affecting online shopping behavior of customers in iran, the derived reference model summarizing antecedents of online shopping proposed by change et al. was us...
Heterogeneity between urban structure and the requirements of the population has given way to cultural and social problems which are sometimes insurmountable in a way that the range of social, economic, and cultural changes has extended to political domains. The absence of a management and planning system and of a democratic supervision, in a centralized one-way approach, affects planning and s...
in this paper, we present a multi-formalism modeling framework (abbreviated by mfmf) for modeling and simulation. the proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. the framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...
