The objective of this paper is to propose a simple tool to estimate the absorption vs. transmission loss contributions of a multilayered blanket unbounded in a double panel structure and thus guide its optimization. The normal incidence airborne sound transmission loss of the double panel structure, without structure-borne connections, is written in terms of three main contributions; (i) sound ...

Using a detailed database of managerial job descriptions, reporting relationships, and compensation structures in over 300 large U.S. firms we find that the number of positions reporting directly to the CEO has gone up significantly over time. We also find that the number of levels between the lowest managers with profit center responsibility (division heads) and the CEO has decreased and more ...

The goal of this paper is to introduce the notions of , -double fuzzy ideals and , -double fuzzy ideal bases where and are strictly two-sided, commutative quanta and also investigate the relationships between these two structures. Then, we construct a functor from the category of , -double fuzzy ideal spaces to the category of , -double fuzzy cotopological spaces. Furthermore, we show the exist...
