A set of experiments on widely different web sites examined the technical accuracy and practicalities of different approaches to using an emulated dial-up link instead of true 56kbps (V.90) dial-up to measure end-user web site experience. The experiments showed that attempts to emulate V.90 dial-up connections by using simple calculations, bandwidth-restricted routers, or sophisticated network ...

As cases of the novel coronavirus disease (COVID-19) continue to rise, so are concerns effects this pandemic could have on people living with HIV. In response pandemic, measures been put in place by African governments limit spread virus. We examine impact these ensuring progress towards HIV advocacy '90-90-90' 2020, i.e., 90% all will know their status, diagnosed receive sustained antiretrovir...

With the growth of Internet, demand for high bit rate Internet access is growing. Even though DSL offers the possibility of very high rate Internet access, the V.90 modems are still the most used method to access Internet from homes. In this paper, we provide a brief review of the voice-band modem technology. We discuss the Internet access model that made V.90 possible. We also provide ways how...

Radiation pneumonitis (RP) is a common complication for radiotherapy of esophageal cancer and is associated with the low dose irradiated lung volume. This study aims to reduce the mean lung dose (MLD) and the relative lung volume at 20 Gy (V 20) and at low dose region using various designs of the fan-shaped complete block (FSCB) in helical tomotherapy. Hypothetical esophageal tumor was delineat...

understanding the development of gully volumes requires the empirical relations between gully volume (v) and length (l) to be established in the field. so far, such v–l relations have been proposed for a limited number of gullies/environments and were especially developed for ephemeral gullies.in this study, v–l relations were established for ephemeral gullies in southern ilam. in order to take...
