So far, there have been introduced many front-end studies, but most of them fail to present, in a consistent way, how the signals are transformed throughout the front-end itself. In this paper, it is intended to introduce a unique presentation of spectrum and signal transformation within RF front-ends. This approach should help researches to have better insight into the high-level modeling and ...

The effects of low molecular weight phenol formaldehyde resin on weathering durability property sweetgum (Liquidambar styraciflua) and southern pine (Pinus taeda) specimens were studied using six wet-dry cycles with ultraviolet light accelerated test following ASTM via evaluating the water repellent efficiency, dimensional stability, crack formation wood. results showed that 1) efficiency treat...

Modern vehicles are equipped with many systems that monitor the security of driving. An example is tyre pressure monitoring system shows a fault if lowered. Low or no at all (0 kPa) means continuing driving may lead to dangerous situation. Prolonged vehicle 0 kPa in ends burst, rim damage, even loss stability. Therefore, on automotive market, manufacturers offer Run Flat tyres adapted emergency...

A bstract We compute the quasi-normal frequencies of scalars in asymptotically-flat microstate geometries that have same charge as a D1-D5-P black hole, but whose long BTZ-like throat ends smooth cap. In general wave equation is not separable, we find class which non-separable term negligible and can using WKB methods. argue our results are universal property all with deeply-capped BTZ throats....

In this article we verify an orbifold version of a conjecture of Nimershiem from 1998. Namely, for every flat n–manifold M, we show that the set of similarity classes of flat metrics on M which occur as a cusp cross-section of a hyperbolic (n+1)–orbifold is dense in the space of similarity classes of flat metrics on M. The set used for density is precisely the set of those classes which arise i...

among 880 studied feet of 7-14 years old children 6.9% suffered mild and severe flat foot. 53.8% of the affected children were symptomatic. as 40.1% of the general population experiences symptoms, in a small proportion of affected persons, symptoms are due to flat foot. the prevalence of symptoms rises with increasing severity of the disorder. in this article, reviewing general aspects of flat ...
