It is used widely in practice, for example, for power allocation to sub-carriers in multi-user OFDM systems such as WiMax. The classic water-filling algorithm is deterministic and requires perfect knowledge of the channel gain to noise ratios. In this paper we consider how to do power ...
DNC Tse,SV Hanly - 《IEEE Transactions on Information Theory》 被引量: 1867发表: 1998年 An efficient waterfilling algorithm for multiple access OFDM In this paper we present a novel and computationally efficient waterfilling algorithm for multiuser OFDM. This algorithm is based on the multiuser wa...
The transport of water in nanoconfined geometries is different from bulk phase and has tremendous implications in nanotechnology and biotechnology. Here molecular dynamics is used to compute the self-diffusion coefficient D of water within nanopores, aro
In addition to its mathematical beauty, the explicit solution allows one to study limiting cases when the crosstalk coefficient is either small or large. We provide an alternative simple proof of the convergence of the iterative water filling algorithm. Furthermore, it turns out that the ...
Kim et al. (2015) developed a new approach (i.e., a modified-micro-genetic algorithm) that can quantify model parameters and structural uncertainties. This approach has been validated for three soil-water models (i.e., Noah LSM, SWAP, and CLM models) under specific hydroclimatic conditions....
Irrigation greening effect over the North China Plain is quantified using a window-searching algorithm with leaf area index (LAI) as a vegetation index Irrigation-induced change in LAI contributes about 34.5% and 14.0% of irrigation cooling effects in March-May and June-September Irrigation effect ...
This algorithm in more detail is described in1. Despite the weak optical contrast between the refractive indices of water and ice (nc = 1.334/1.301 = 1.025), even with a flat interface between these two media, a photonic hook is formed in the shadow part of the spherical drop ...

We first compute the self free energy of a viral particle approaching an air-water interface (κ2 = 0, ϵ2/ϵ1 = 1/80), by using a relaxation algorithm to solve Eq. (1) (see SI, Supplementary Note 1). Typically we take κ1R = 20, δ/R = 0.125 and σ*...
