A new adaptive RWA (Routing and Wavelength Assignment) algorithm is proposed, which may be used in photonic networks with no wavelength conversion. The problem we address is how to increase the utilization of WDM network resources by taking account of future demand efficiently. In the proposed method, blocking probability is minimized by taking account of future path establishment, using a meth...

In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...

This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...

Statnamic load testing has been used extensively all over the world on bridges, high rise condominium structures, office towers, military facilities, Corps of Engineers flood control structures, water and wastewater facilities and various other commercial structures. Statnamic Load Testing is a recognized test method by the American Society for Testing and Materials designation number ASTM D738...

Thermal expansion of a member can affect structural bearing capacity when one or more members are subjected to fire. To explore the developmental rule internal force in latticed shell structure, computation method sensitivity is presented based on alternate path method. Taking K8 single-layer structure as analysis object, finite element models established by ANSYS, applying temperature loads ra...

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...
