AN EXTENDED RESONATOR CONCEPT AND ITS APPLICATION IN SWITCHED-CAPACITOR DFT PROCESSORS

An extension of the method based on the Goertzel-algorithm is given applying general two-output second-order lossless discrete resonators. In the proposed structure of resonators simple SC integrators are used avoiding the problems of circuit complexity of SC delay elements. The different resonators of the bank are of the same topology and differ only by one capacitor value. The solution is, therefore, very suitable for integration

SIS epidemic propagation on hypergraphs

Mathematical modeling of epidemic propagation on networks is extended to hypergraphs in order to account for both the community structure and the nonlinear dependence of the infection pressure on the number of infected neighbours. The exact master equations of the propagation process are derived for an arbitrary hypergraph given by its incidence matrix. Based on these, moment closure approximation and mean-field models are introduced and compared to individual-based stochastic simulations. The simulation algorithm, developed for networks, is extended to hypergraphs. The effects of hypergraph structure and the model parameters are investigated via individual-based simulation results

Measuring the Macroeconomic Performance of Public Finance Management

In international practice, the performance of public finance management is usually assessed on the basis of quality indicators of the subsystems of the public finance system. The experts of the State Audit Office of Hungary have developed an evaluation system capable of measuring the performance of public finance management on the basis of quantitative indicators and quantifying the contribution of the factors that determine performance most. This article describes this system. It also shows how the assessment system was used to analyse the risks to the ongoing reduction of Hungarian public debt

Optimal Multi-TDMA Scheduling in Ring Topology Networks

A scheduling algorithm will be proposed for wireless ring topology networks, utilizing time division multiple access (TDMA) with possible simultaneous operation of nodes. The proposed algorithm finds the optimal schedule to minimize the turnaround time for messages in the network. The properties of the algorithm are mathematically analyzed and proven, and practical test results are also provided

Ügyfélkapcsolat menedzsment rendszerek nyílt forráskódú szoftverekkel

The object of this study is a comprehensive review of the open source customer relationship management (CRM) systems. The open source softwares have become one of the most important trends in the software industry recently. Similarly, the CRM systems are applied more increasingly in several fields of economy. The CRM is not merely a subsequent software technology and application in the field of Business Intelligence, but rather a novel, comprehensive customercentric approach to an organization’s philosophy in dealing with its customer for the sake of realization of short- and long-range business target contrary to the traditionally widespread productcentric approach. Following a short synopsis of the theoretical and practical aspects of the CRM systems we analyse the scope of CRM-supported business activities and processes, then the actual market forecasts and the range of the effective and potential users of the proprietary and open source CRM solutions. We make an attempt to give a general overview of the advantages and disadvantages of applying open source CRM software solutions including the discussion of user benefits and costs and the applied software technologies
