The purpose of the present work is to introduce the concept of bifuzzy core of a fuzzy automaton, which induces a bifuzzy topology on the state-set of this fuzzy automaton. This is shown that this bifuzzy topology can be used to characterize the concepts such as bifuzzy family of submachines, bifuzzy separable family and bifuzzy retrievable family of a fuzzy automaton.

Core-shell nanostructures are emerging as more important materials than alloy nanostructures and have much more interesting potential applications in various fields. In this work, we demonstrated the fast and facile synthesis of core-shell nanoparticles consisting of Pt thin layer as the shell and Ni nanoparticles as the cores. The described method herein is suitable for large-scale and low-cos...

as an international legal instrument, the international health regulations (ihr) is internationally binding in 196 countries, especially in all the member states of the world health organization (who). the ihr aims to prevent, protect against, control, and respond to the international spread of disease and aims to cut out unnecessary interruptions to traffic and trade. to meet ihr requirements,...

aluminum foams are a novel branch of advanced materials with superior properties. sandwich structures with aluminum foam core are good energy absorbers. in this paper, mechanical properties and energy absorption of aluminum foam sandwich panels subjected to quasi-static perforation tests with conical-nosed indenter were investigated experimentally. for this purpose sandwich panels consisting of...

introduction: ski is a fast sport with a high risk of falling. the purpose of this study is to investigate the relationship of core strength with static and dynamic balance in snowboarders. materials and methods: forty male athletes participated in this study with a history activity of at least 6 seasons in snowboard skiing sport (mean age 26.85±3.30yr, height 180.45±6.08cm, weight 79.86±6.14kg...

background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...
