We present a new approach to display High Dynamic Range (HDR) video using gradient based high dynamic range compression. To obtain HDR video, we utilize the split aperture camera. We apply a spatio-temporal gradient based video integration algorithm for fast and accurate integration of the three input HDR videos into a low dynamic range video, which is suitable for display. The spatiotemporal v...

The in-plane seismic performance of old unreinforced brick masonry walls strengthened with stainless-steel twisted bars and conventional steel (usually used in concrete reinforcing) was investigated the present study. For this purpose, a total seventeen wallettes reproducing traditional Lisbon buildings from 1930s–1950s (known as “placa” buildings) were constructed. specimens assembled using or...

The rapid growth of multimedia applications has increased interest in the compression of video data. This paper presents a new method for improving the compression ratio of video data, which can be easily used in a multilayer environment for error resilience applications as well. Data of four luminance blocks in a macroblock are processed and arranged in such a way that important macroblock dat...

‎A universal schema for diagonalization was popularized by N.S‎. ‎Yanofsky (2003)‎, ‎based on a pioneering work of F.W‎. ‎Lawvere (1969)‎, ‎in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function‎. ‎It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema‎. ‎Here‎, ‎we fi...

The article justifies the existence an imbalance in provision of video information services using infocommunication networks. It is shown that such due to destructive actions opposing side. Many these attacks relate disabling energy and telecommunications infrastructure. This leads a significant drop bandwidth network. Accordingly, it necessary localize between load network its face crisis fact...

Systems of linear differential equations with constant coefficients, as well as Lotka–Volterra equations, with delays in the off–diagonal terms are considered. Such systems are shown to be asymptotically stable for any choice of delays if and only if the matrix has a negative weakly dominant diagonal.

buildings with wall or frame-wall systems are more effective against earthquake forces and sustain less damage than buildings which their lateral resistance is solely depends on frames. four reinforced concrete (rc) structural wall specimens were subjected to cyclic loading using finite elements method with abaqus software in order to study influence of diagonal web reinforcement. the research ...
