The maximum principal stress, von Mises equivalent stress, equivalent creep strain in dissimilar welded joints between martensitic heat-resistant steel (T91) and bainitic heat-resistant steel (G102) are simulated by FEM under the conditions of 833K and inner pressure of 28MPa. The results show that the maximum principal stress and von Mises equivalent stress are quit high in the vicinity of weld/G102...
Due to the dynamic topology, limited resources and unpredictable channel conditions, the strict layered design is not flexible enough to cope with the wireless ad hoc and sensor network environment. This paper presents an in-depth analysis of difficulties in cross-layer design and the latest cross-layering approaches for wireless ad hoc and sensor networks. According to the number of layers involved...
