JavaScript is nowadays the lingua franca of web browsers. This programming language is not only the main tool that developers have to implement the client side of web applications, but it is also the target of frameworks such as Google Web Toolkit. Given this importance, it is fundamental that JavaScript programs can be executed efficiently. Just-in-time (JIT) compilation is one of the keys to ...

In this paper, the downlink sector capacity of a cigar-shaped microcells using wideband code-division multiple-access (WCDMA) with soft hand-over (SHO) mode is analyzed. The two-slope propagation loss with log-normal shadowing is used in the analysis where a model of eight cigar-shaped microcells is utilized to calculate the downlink sector capacity. The performance of the downlink is studied f...

In this paper we investigate a susceptible-infected-susceptible (SIS) epidemic model describing data dissemination in opportunistic networks with heterogeneous setting of transmission parameters. We obtained the estimation of the final epidemic size assuming that amount of data transferred between network nodes possesses a Pareto distribution, implying scale-free properties. In this context, mo...

The problem of inverse scattering of a plane acoustic wave by a penetrable scatterer with the transmission boundary condition is studied. It is proved that, if the constant exterior wavenumber is known, then the shape of the obstacle and the constant transmission parameter and the constant interior wavenumber are uniquely determined by the scattering amplitude known at the constant exterior wav...

The clumping parameter related to the distribution of schistosome parasites is obtained by fitting a negative binomial distribution to data collected from patients in a village in Brazil; the natural uninfected and parasite-induced snail host mortality rates are obtained from laboratory data. These values are used in a schistosomiasis model proposed earlier by the authors, and a disease transmi...

We investigate the dynamics of the extended simple point charge (SPC/E) model of water in the supercooled region. The dynamics at negative pressures show a minimum in the diffusion constant D when the density is decreased at constant temperature, complementary to the known maximum of D at higher pressures. A similar trend in the rotational diffusion is also observed.

plane and is composed of "large" corrugations or bumps—large in the sense that the radius of curvature at any point of S is much larger than a wavelength. Above S there is a field (x, y, z)e~""1 which varies harmonically in time with the radial frequency to and which satisfies the wave equation W + k2ip = — 4ttt, (1) k being the propagation constant co/c and r the distribution of sources.
