-The determination of mechanical properties of materials at elevated temperatu~; presents difficulties, particularly when the material to be tested is subject to oxidation. Various methods have been employed to permit the evaluation of high temperature creep properties. The method described in this paper was developed on the basis of modifications of a technique developed for the protection of ...

Large-scale distributed denial of service (DoS) attacks are an unfortunate everyday reality on the Internet. They are simple to execute and with the growing prevalence and size of botnets more effective than ever. Although much progress has been made in developing techniques to address DoS attacks, no existing solution is unilaterally deployable, works with the Internet model of open access and...

The Great Recession was characterized by two related phenomena: (i) a jobless recovery and (ii) a permanent drop in aggregate output. Data show that the United States, Europe, and even countries with lesser ties to the international …nancial system have su¤ered large permanent losses in aggregate output and employment since the …nancial crisis, despite unprecedented monetary injections. However...

Geopolymers are known as high strength and durable construction materials but have a brittle fracture. In practice, this results in a sudden collapse at ultimate load, without any chance of preventing the breakdown of parts or of withstanding the stress for some time. Glass fiber usage as a total anisotropic shape acting as a compact structure component should hinder the fracture mechanism. The...
