In this paper a system for the recognition of printed Tifinagh characters is presented. It is divided into three main steps: preprocessing, feature extraction, and classification. Image quality is enhanced through preprocessing which are: binarization, normalization and thinning. Then the image...

The nature of the dynamics of opinion formation or zero-temperature Ising models modeled as a decision-by-majority process in complex networks is investigated using eigenmode analysis. The Hamiltonian of the system is defined and estimated by eigenvectors of the adjacency matrix constructed from...

В статье рассматриваются стохастические системы управления с импульсными воздействиями, которые образуют гиперэрланговские потоки событий и приводят к...

We document evolving patterns in the inflation-unemployment relationship in Australia in the frequency domain under different monetary policy regimes and labor market regulations. The RBA adopted monetary targeting in 1976 and inflation targeting in 1993. There were important changes in the...

<Para ID="Par1">In this paper, we investigate the optimal control problems governed by elliptic equations with integral constraint for state variable in one dimension by Legendre–Galerkin spectral methods. We deduce optimal conditions of the optimal control problems. Meanwhile, we obtain an a priori error...</para>

Many networks of interest in the science, including social networks, computer networks and the World Wide Web, are found to be divided naturally into communities or groups. The problem of detecting communities is one of the outstanding issues in the study of network systems. Based on the...

Functional integrals constitute a powerful tool in the investigation of financial models. In the recent econophysics literature, this technique was successfully used for the pricing of a number of derivative securities. In the present contribution, we introduce this approach to the field of...

In this paper, we are concerned with centered Markov Additive Processes {(Xt,Yt)}t∈T where the driving Markov process {Xt}t∈T has a finite state space. Under suitable conditions, we provide a local limit theorem for the density of the absolutely continuous part of the probability...

We present the Phillips curve in Australia in the frequency domain and document an evolving pattern in its slope at low frequencies under different monetary policy regimes and labor market regulations. The RBA adopted monetary targeting in 1976 and inflation targeting in 1993. There were...
