the reciprocal degree distance (rdd)‎, ‎defined for a connected graph $g$ as vertex-degree-weighted sum of the reciprocal distances‎, ‎that is‎, ‎$rdd(g) =sumlimits_{u,vin v(g)}frac{d_g(u)‎ + ‎d_g(v)}{d_g(u,v)}.$ the reciprocal degree distance is a weight version of the harary index‎, ‎just as the degree distance is a weight version of the wiener index‎. ‎in this paper‎, ‎we present exact formu...

application of appropriate agricultural operations is a strategy to reduce energy consumption and greenhouse gas emissions from agricultural productions process. in this study, fuel consumption and greenhouse gases emissions values for each farm operation was evaluated in gorgan and ali-abad katol to soybean product. all activities and production processes about operations were monitored and re...

in competitive markets, the operations strategies of companies are normally formulated based on their competitive advantages. an effective operations strategy should maintain and improve competitive advantages based on the capabilities of the corporate operations resources. considering the market requirements and the operational performance of the rivals is the key for success and survival of a...

Fuller, in 1989, described probiotic microorganisms as “a live microbial feed supplement,which beneficially affects the host animal, by improving its intestinal microbial balance”.Saccharomyces cerevisiae var. boulardii (S.boulardii) is an accurate probiotic yeast idol.The detection and budding of S.boulardiiis firmly related to the impression of healthinessto promote microorganisms from foodst...

In this paper, some elementary operations on triangular fuzzynumbers (TFNs) are defined. We also define some operations on triangularfuzzy matrices (TFMs) such as trace and triangular fuzzy determinant(TFD). Using elementary operations, some important properties of TFMs arepresented. The concept of adjoints on TFM is discussed and some of theirproperties are. Some special types of TFMs (e.g. pu...
