Hybrids as various resources have valuable importance in tree breeding. Today, improvement programs by using poplar and willows and their hybrids play basic role in supplying wood and decreasing pressure on natural forests. This research was carried out in order to study inter-generic hybridization possibility between Salix aegyptica and Populus caspica species from Salicaceae to achieve new hy...

In this paper, the stability analysis and control design of heterogeneous traffic flow is considered. It is assumed that the traffic flow consists of infinite number of cooperative non-identical vehicular platoons. Two different networks are investigated in stability analysis of heterogeneous traffic flow: 1) inter-platoon network which deals with the communication topology of lead vehicles and...

institutional synergy in urban management, as a collective feature is the byproduct of inter and intra institutional activities of urban organizations. it is consider gregarious action and as managerial phenomenon with feature of trust, participation. cooperation engagement, facilitation, mutual recognition and the network. this article scrutiny the capacity of inters intuitional synergy in urb...

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...
