Considering the vulnerability of double-layer grid space structures to progressive collapse phenomenon, it is necessary to pay special attention to this phenomenon in the design process. Alternate path method is one of the most appropriate and accepted methods for progressive collapse resistant design of structures. Alternate Path Method permits local failure to occur but provides alternate pat...

Alternate paths may significantly improve reliability of routing protocols. We develop a fast alternate path-finding algorithm for our proposed Reliable OSPF (ROSPF) routing protocol. This algorithm is based on the Dijkstra’s shortest path algorithm and a logarithmic edge-increment procedure. Three partially disjoint paths can be calculated in time complexity O(N*logN*logW0), where N and W0 rep...

Explicit routing and the pre-allocation of network resources are essential to achieve absolute end-to-end QoS guarantees in networks. MPLS (MultProtocol Label Switching) provides a good platform to implement explicit routing and also supports pre-establishment of multiple explicit routes for a source-destination pair. We show that MPLS can achieve reliable explicit routing, by deploying maximal...

Extensive research has been focused on the progressive collapse analysis of buildings and most of them are based on the alternative path method (APM) with sudden removal of one or several columns. However, in this method the damage of adjacent elements of removed columns under blast conditions was ignored and this issue can lead to an incorrect prediction of progressive collapse. Therefore, in ...

The effect of antimycin A on the respiration of fresh potato (Solanum tuberosum var. Russet Burbank) slices has been determined in the presence and absence of m-chlorobenzhydroxamic acid (CLAM). Two antimycin-binding sites are indicated. At low concentrations antimycin alone inhibits respiration only slightly. When CLAM and low antimycin are added together, respiration is sharply inhibited, as ...

In this study, the progressive collapse potential of seismically designed steel plate shear wall (SPSW) systems is investigated using the alternate path method, and their performances are compared with those of the conventional special moment frame (SMF) systems. Nonlinear static and dynamic analyses are conducted to follow the progressive collapse of the structures, and their ability of absorb...
