This paper presents a scheme for size optimization of statically loaded truss structures under stress and deformation constraints. The method employs maximum stress values of design parameters as initial design and a two level multipoint approximations for constraint approximation along with interior point algorithm for optimization. Interior point algorithm is imposed, instead of dual method, for...
Using the high fidelity model in the multidisciplinary design optimization (MDO) application is becoming more and more popular, but it brings complex coupling relationship and huge computing intensity, which need efforts to be well organized to reduce the computation time. In this paper, a parallel computing environment distributed in local area network (LAN) was established based on the collaborative...
An IA-RWA computation with QoT compensation based on double Cooperating PCEs is presented and extended AMSON testbed is verified. Two kinds of IA-RWA computation with QoT compensation strategies including Cooperating PCEs based and RSVP based strategies are demonstrated and compared.
Localization is an important application in wireless sensor network for mobile computing. Range-based and range-free localization technologies are discussed in this paper. As one of most famous range-free location technologies, DV-Hop algorithm is introduced in detail and is simulated in AlgoSenSim. The simulation results show the influence of distribution of sensor nodes on network connectivity in...
