Why do stabilized images fade? How can X cells in the retina respond linearly to a broad range of spatiotemporal stimulation functions in spite of possible nonlinear preprocessing? Why have models of spatial vision that utilize static images and assume linearity of preprocessing led to reasonable results in spite of the two questions above? This chapter introduces the push-pull shunting network...

Writing concurrent programs with shared memory is often not trivial. Correctly synchronising the threads and handling the non-determinism of executions require a good understanding of the interleaving semantics. Yet, interleavings are not sufficient to model correctly the executions of modern, multicore processors. These executions follow rules that are weaker than those observed by the interle...

The dynamic fiber/matrix interface strength for a silicon-carbide-fiber-reinforced, titanium-alloy metal-matrix composite was measured by impacting the end of a fiber extending through a thin specimen with a diamond-tipped projectile at ~2 m/s. The matrix surrounding the distal end of the fiber was supported on the end of a Hopkinson bar fabricated from hypodermic needle tubing, and an interfer...

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...

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...

The PoC (Push-to-talk over Cellular) application allows point-to-point, or point-to-multipoint voice communication between mobile network users. The related work over PoC focuses on the performance analysis only and is completely ignorant about dimensioning PoC controller to optimize revenue for service providers. In this paper, we dimension a PoC controller with the assumption that the network...

In this paper, the mean-centered first-order second-moment FOSM method is employed to perform probabilistic push-over analysis POA of structural and/or soil-structure systems. Approximations of first and second statistical moments FSSMs of engineering demand parameters EDPs of structural and/or geotechnical systems with random material parameters are computed based on finiteelement FE response ...
