Underwater wireless optical communications are knowing a high interest in recent years, with many military and civil applications. The design of efficient systems relies on powerful simulation tools. most used algorithms based paper from 1989, written by Prahl designed for light propagation through human tissue. This method Monte Carlo Simulation, following the path photon participating media. ...

The results showed that parents gave messages (decoding) to adolescents related character education: religious, hard work, creative, independent, democratic, curiosity, love of the motherland, mutual respect, communicative, peace-loving, honest , diligent, care for environment, responsible and social spirit. Parents convey education teenagers when they are relaxed, children happy, there is toge...

Informetric/bibliometric analyses have to a large extent been relying on an assumption that research is essentially cumulative in its nature, which is not the least visible in the rational for using citation analyses to assess quality of research. However, when reviewing both the theoretical literature on how research is organized and studies analyzing the structures of research fields through ...

In this paper, we introduce a deterministic fluid model and two stochastic traffic models for wireless networks. The setting is a highway with multiple entrances and exits. Vehicles are classified as calling or non-calling, depending on whether they have calls in progress. The deterministic model ignores the behavior of individual vehicles and treats them as a continuous fluid, whereas the stoc...

In this paper, we investigate the performance of statistical language models on Instant Messaging (IM) data. Language Models (LM) are quite useful for modeling text data, and hence they are helpful in different contexts like spelling correction, speech recognition, part-ofspeech tagging etc. Construction of LM on a users past messaging data would be a strategy to model her writing style, and th...

Cellular systems have hitherto been modeled mostly by graphs for the purpose of channel assignment. However, hypergraph modeling of cellular systems offers a significant advantage over graph modeling in terms of the total traffic carried by the system. For example, we show that a 37-cell system when modeled by a hypergraph carries around 30% more traffic than when modeled by a graph. We study t...

We consider a variant of so called power-law random graph. A sequence of expected degrees corresponds to a power-law degree distribution with finite mean and infinite variance. In previous works the asymptotic picture with number of nodes limiting to infinity has been considered. It was found that an interesting structure appears. It has resemblance with such graphs like the Internet graph. Som...
