In this paper, an experimental investigation of the integration PCM capsules as insulation material into outer or inner rows hollow brick to find out optimum location that give best thermal performance a wall. A test model consists two identical cubical rooms was designed and fabricated wall with without in natural outdoor condition Diwaniyah city Iraq during summer. The results show will reduc...

In a utopian world, our communication technology would have “brick wall” filters, nodistortion amplifiers and mixers, and well-coordinated spectrum operations. In the real world, communications are prone to various types of unintentional and intentional interference of technogenic (man-made) origin that can disrupt critical defense communication systems, with the impacts ranging from slight red...

By using Hawking’s treatment as well as Zaslavskii’s treatment respectively and the brick wall model, two different values of classical entropy and quantum entropy of scalar fields in the two-dimensional extreme charged dilaton black hole backgrounds have been obtained. A new divergent term emerges in the quantum entropy under the extreme limit for Zaslavskii’s treatment and its connection with...

We review the way the BTZ black hole relaxes back to thermal equilibrium after a small perturbation and how it is seen in the boundary (finite volume) CFT. The unitarity requires the relaxation to be quasi-periodic. It is preserved in the CFT but is not obvious in the case of the semiclassical black hole the relaxation of which is driven by complex quasi-normal modes. We discuss two ways of mod...

west coast stations in South Kanara district. The water from this well was found to be of very fair quality for either purpose at the time of its construction and for some time thereafter. During the last twelve months, however, there has been a progressive deterioration in the aesthetic qualities of the water, although the chemical features had not appreciably changed since 1931. The water ass...

In computer graphics, Wang tiles are used as a tool to generate non periodic textures and patterns. We develop a framework and a method for the tiling problem which is suitable for applications. In particular, we apply our methodology to a special kind of Wang tiles, called Brick Wang tiles, introduced by Derouet-Jourdan et al. in 2015 to model wall patterns. We generalise their result by provi...

We discuss massive scalar perturbations of a Schwarzschild black hole. We argue that quantum effects alter the effective potential near the horizon resulting in Poincaré recurrences in Green functions. Results at the semi-classical level are independent of the details of the modification of the potential provided its minimum near the horizon is inversely proportional to the square of the Poinca...

As the dominating CMOS technology is fast approaching a “brick wall,” new opportunities arise for competing solutions. Nanoelectronics has achieved several breakthroughs lately and promises to overcome many of the limitations intrinsic to current semiconductor approaches. Most of the results in this area reported until now focus on devices and interconnect; this work goes several steps further ...

Records on recovery after cholecystectomy of patients in a suburban Pennsylvania hospital between 1972 and 1981 were examined to determine whether assignment to a room with a window view of a natural setting might have restorative influences. Twenty-three surgical patients assigned to rooms with windows looking out on a natural scene had shorter postoperative hospital stays, received fewer nega...

built of brick. At its base will be two hydrocarbon burners. Upper and lower triangular flues extend across the middle of the shaft, and also an upper and lower set of baffles or side wings, which are connected by means of wall passages or flues. Underneath these is a shelf, forming a retort in which air may mix with the flames from the burners. Flues are provided for the return of the gases ar...
