statement of problem: the connector area is the weakest zone of an all-ceramic fixed partial denture (fpd), where most catastrophic failures of the prostheses tend to occur. purpose: the aim of the present study was to assess the effect of the convergence angle of abutments on the fracture resistance of three-unit fixed partial dentures made of ips-empress2. materials and methods: forty extract...

Fuzzy set theory has entered into a large variety of disciplines of sciences,technology and humanities having established itself as an extremely versatileinterdisciplinary research area. Accordingly different notions of fuzzystructure have been developed such as fuzzy normed linear space, fuzzytopological vector space, fuzzy sequence space etc. While reviewing theliterature in fuzzy sequence sp...

Abstract—The least mean square (LMS) algorithm is one of the most well-known algorithms for mobile communication systems due to its implementation simplicity. However, the main limitation is its relatively slow convergence rate. In this paper, a booster using the concept of Markov chains is proposed to speed up the convergence rate of LMS algorithms. The nature of Markov chains makes it possibl...

in present study, role of agricultural on eco countries regional convergence was assessed in dynamic panel data model. at first, eco countries convergence and agricultural sector effect in convergence acceleration was surveyed by generalized method of moments (gmm) over the period 1996-2005. results showed that, this is convergence between eco countries. in spite of increasing regional growth, ...
