To solve customer complaints better for some telecommunication enterprises, a new method through combined rasterization of Geography Information System (GIS) is presented in this paper. By the combined rasterization of surface features and landforms, the historical customer complaints and the realtime state of network will be utilized to handle new complaints simultaneously. Also, an innovative...

The crossover operator is the most innovative and relevant operator in realcoded genetic algorithms. In this work we propose a new strategy to improve the performance of this operator by the creation of virtual parents obtained from the population parameters of localisation and dispersion of the best individuals. The idea consists of mating these virtual parents with individuals of the populati...

This paper presents a novel method for the secure management of digital images formulated within the mathematical theory of polynomial interpolation. As main innovative features, our approach is based on a hierarchical joint ownership of the image by a trusted layered authority and on a deterministic watermarking procedure, embedding a short meaningful or random signature into the image. Experi...

Today, telecom operators face a threefold challenge: a social challenge dealing with the evolution of the consumer lifestyle, a technological challenge dealing with ever changing ICT trends and a business challenge dealing with the need for innovative business models. This paper introduces an idea of group-oriented services, a special type of personalized telecom services, as a possible solutio...

Behavior composition is a means to achieve modularity and adaptability. Unlike process algebra, SDL does not explicitly define composition operators. In this paper, we propose design patterns and rules for expressing elementary behaviors called roles and their composition in SDL. The composite state concept newly introduced in SDL-2000 is used in an original and innovative way to model roles an...

This project leverages on the new PAR in Norman, Oklahoma to exploit phased array technology and its applications to improve NWP through EnKF data assimilation with the goal of improving environmental characterization and forecast to optimize naval operation. This project will further enhance the existing collaboration among ONR, National Serve Storms Laboratory (NSSL), and the University of Ok...

This paper examines the first 16 months of competition in the German market for long-distance voice telephony on the fixed network. It concentrates on price level and price structure. Competition induced by the entry of both network operators and switch-based service providers decreased the price level substantially. Furthermore, after initial attempts to design innovative price structures, mos...

Behaviour composition is a means to achieve modularity and adaptability. Differently from process algebra, SDL does not explicitly define composition operators. In this paper, we propose design patterns and rules for expressing elementary behaviours called roles and their composition in SDL. The composite state concept newly introduced in SDL-2000 is used in an original and innovative way to mo...

In this paper, we introduce subspace-frequently hypercyclic operators. We show that these operators are subspace-hypercyclic and there are subspace-hypercyclic  operators that are not subspace-frequently hypercyclic. There is a criterion like to subspace-hypercyclicity criterion that implies subspace-frequent hypercyclicity and if an operator $T$ satisfies this criterion, then $Toplus T$ is sub...

The presence of outliers in time series can seriously affect the model specification and parameter estimation. To avoid these adverse effects, it is essential to detect these outliers and remove them from time series. By the Bayesian statistical theory, this article proposes a method for simultaneously detecting the additive outlier (AO) and innovative outlier (IO) in an autoregressive moving-a...
