Progressive collapse assessment of a reinforced concrete (RC) building designed only for gravity loads and lacking dedicated lateral load resisting system was carried out using the alternate path (ALP) method finite element (FEM) numerical model created in software SAP2000. Plastic hinge capacity members evaluated considering flexure (M), axial force (N) shear (V) interaction validated procedur...

This paper focuses in the selection of an optimal path pair for cooperative diversity based on cross-layer optimization in multihop wireless ad hoc networks. Cross-layer performance indicators, including power consumption, signal-to-noise ratio, and load variance are optimized using multi-objective optimization (MOO) with Pareto method. Consequently, optimization can be performed simultaneously...

AMUact--No single optimization method exists that is best suited to solve all path generation problems effectively [Erdman 1991]. Graphical illustrations of the mechanism design space, given in this paper, attest to the difficulties encountered in the optimization of path generation tasks. An example has also been provided to illustrate the importance of a good initial guess in achieving proper...

This paper analytically examines two vibration paths rank ordering methods and critically investigates several path identification issues. One method is the indirect interfacial path force estimation procedure that is employed in the well known experimental transfer path analysis. The other method is path disconnect scheme that has been historically utilized in industry to empirically find a do...

Routing algorithm is a challenge for a mobile ad hoc network (MANET), but current routing protocols for MANET consider the path with minimum number of hops as the optimal path to a given destination. This strategy does not balance the traffic load over a MANET, and may result in some disadvantages such as creating congested area, depleting power faster and enlarging time delay in the nodes with...

Recent studies have demonstrated the utility of alternate paths in improving connectivity of two end hosts. However studies that comprehensively evaluate the tradeoff between its effectiveness and overhead are lacking. In this paper we carefully characterize and evaluate the trade-off between (1) the efficacies of alternate path routing in improving end-to-end delay and loss, and (2) the overhe...

In this study, an extended stress-based forming limit diagram (FLD) for prediction of necking based on the Marciniak and Kucznski (M-K) model is represented and applied in tube hydroforming. The bulge forming of a straight tube is simulated by finite element method and verified with published experimental data. This adaptive simulation technique is based on the ability to detect the onset an...

Routing in wavelength-routed all-optical WDM networks has received much attention in the past decade for which fixed and dynamic routing methods have been proposed. Taking into account the observation that wavelength-routed all-optical WDM networks are similar to circuit-switched voice networks, except with regard to wavelength conversion, we propose an adaptive alternate routing (AAR) scheme f...

In nonhierarchical circuit-switched networks, calls can be routed to alternate paths if the direct path is blocked. In this paper, we analyze two alternate-path routing rules called the Madmum Free Circuit routing and the Madmum Free Circuit with Minimm Occupied channel routing. For convenience, we shall call them the M and M2 routings respectively. In the use ofMrouting, acall isrouted toanalt...
