CASPA constitutes a push-button tool for automatically proving secrecy and authenticity properties of cryptographic protocols. The tool is grounded on a novel technique for causality-based abstraction of protocol executions that allows establishing proofs of security for an unbounded number of concurrent protocol executions in an automated manner. We demonstrate the expressiveness and efficienc...

Response modification factor (R-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. Relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. The present paper tries to evaluate the R-factors of conventional concentric braced frames (CBFs) and special moment frames (MRFs) in ...

The success of the World Wide Web has led to a steep increase in the user population and the amount of traffic on the Internet. Popular Web pages create “hot spots” of network load due to their great demand for bandwidth and increase the response time because of the overload on the Web servers. We propose the distribution of very popular and frequently changing Web documents using continuous mu...

Consider a fully connected network of nodes, some of which have a piece of data to be disseminated to the whole network. We analyze the following push-type epidemic algorithm: in each push round, every node that has the data, i.e., every infected node, randomly chooses c other nodes in the network and transmits, i.e., pushes, the data to them. We write this round dynamically as a random walk wh...

BACKGROUND Although the recently developed Pressure Ulcer Scale for Healing (PUSH) was created to monitor healing over time, prospective evidence of its validity in measuring healing is lacking. The purpose of this study was to assess the validity of PUSH (version 3.0) when used to assess pressure ulcers in clinical practice. METHODS The authors chose a prospective research design using a con...
