Research ArticleOpen accessPhrase in the titleDynamic Propagation Problems of Mode III Semi-Infinite CrackLu Nian-Chun, Li Xin-Gang, Cheng Yun-Hong, Cheng JinBy means of the theory of complex functions, dynamic propagation problems of mode III semi- infinite crack were researched. The problems studied can be facilely transformed into riemann-hilbert problems and the universal expression of analytical solutions of stress, displacement and dynamic stress intensity factor under the conditions of moving increasing loads Px/t and Pt2/x, respectively, are very facilely obtained using … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 7,281 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImpact of the Smart City Architecture, Speed and Traffic Density of Vehicles on the Performances of VanetsAbdallah Rhattoy, Mohamed Lahmer, Idriss ChanaVehicular Ad-hoc Networks (VANET) is one of the emerging and actual research fields in automotive companies and Intelligent Transportation Systems (ITS) designers. In the Smart City the presence of such networks opens the way for a wide range of applications such as safety applications, mobility and connectivity for both driver and passengers to exploit the transport systems in a smoothly … …Journal of Computer Science, Vol. 13, Issue 11 · 15 Nov 2017 · 7,538 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDynamic Analysis of Structures Using Neural NetworksN. Ahmadi, R. Kamyab Moghadas, A. LavaeiIn the recent years, neural networks are considered as the best candidate for fast approximation with arbitrary accuracy in the time consuming problems. Dynamic analysis of structures against earthquake has the time consuming process. We employed two kinds of neural networks: Generalized Regression neural network (GR) and Back-Propagation Wavenet neural network (BPW), for approximating of dynamic time history response of … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,154 accessesView PDF Cite
