A balanced part ternary design (BPTD) is a balanced ternary design (BTD) with a specified number of blocks, say b2, each having repeated elements. We prove some necessary conditions on b2 and show the existence of some particular BPTDs. We also give constructions of infinite families of BPTDs with b1 = 0, including families of ternary t-designs with t ≥ 3.

An-balanced pair in a partially ordered set P = (X; <) is a pair (x; y) of elements of X such that the proportion of linear extensions of P with x below y lies between and 1 ?. The 1=3 ? 2=3 Conjecture states that, in every nite partial order P , not a chain, there is a 1 3-balanced pair. This was rst conjectured in a 1968 paper of Kislitsyn, and remains unsolved. We survey progress towards a r...

In this paper, we are going to investigate the growth of the Iranian maritime transport with a focus mainly on the North - South transit Corridor, review of dry ports in order to support the Iranian container terminals at the south ports in order to increase the volume of container storages at the terminals. For the purpose of assessing the outcome of port operational management, the Balanced ...

this article wants to propose this theory that farm corporations are agropolitan development models in iran. as over-concentrating investments to the urban areas did not lead to a trickledown effect to the rural areas. to the extreme, there are ideas to minimize linkages with the urban economy, and to make the rural areas pursue self-sufficiency by maximizing its potentials. however, against th...

need to progress is the factors contributing to development and trying to meet these requirements cause which organization will lead to the development. organizations performance evaluating, is one of the most powerful management tools that we can by that, obtained required information of organization status .in this study, a performance evaluation model based on balanced scorecard (bsc), which...

Universities have a magnificent role in the sustainable development of their country and international scientific production of their country. Purpose of this paper is expansion of using balance scorecard in universities In order to improve performance of universities in learning and educating. The Balanced Scorecard (BSC) is an extensively adopted performance management framework in a lot of o...
