Historical development and theoretical basics of workforce management systems are presented in the paper. Fundamental of paper is the issue of modelling and simulation of Workforce management systems. The output is simulation model. Results of simulations and their compliance with the real data are discussed in conclusion. The paper is based on extensive real data that the authors obtained from the most important Czech power distribution and telecommunications operators.

  • Annotation:
    This paper aims to describe a benchmarking methodology for testing the performance of IP protocols in industrial and control networks with regard to the deployment of Smart Grids. Based on the ITU recommendation and definitions, the paper summarizes the general communication requirements for ICT networks and confronts them with the requirements set out in the standards for specific types of industrial and control network implementations such as electrical power industry, water industry, transport industry, etc. The paper provides qualitative parameters, which aim to characterize the transmission characteristics of IP protocol based on confrontation of the communication requirements. It is necessary to define general data streams that are typical for industrial and control networks and measurement scenarios for measuring these transmission characteristics. Finally, the paper defines the minimum topology of test network and minimal configuration of network elements where the methodology for testing IP protocols is demonstrated.

  • Annotation:
    Smart Grids are current stage in power grids evolution. This trend brings increased demands on network management and it results in the need for greater involvement of ICT technologies to power grids. In telecommunications, managing large ICT networks is traditionally handled at high level and has been described by standardized process frameworks. One of the most important process frameworks is Frameworx by TM Forum. It is generally assumed that the processes from the telecommunications can be adapted to the Smart Grids. This paper addresses the use of existing techniques from the field of telecommunications, especially the Frameworx in the power grid sector. This aim is achieved through modeling and simulation of processes in the power grid using the processes described for telecommunications networks. The output of the paper is to assess the suitability of the usage of formalized process frameworks in the field of power grids.

    The market for fixed and mobile services is nearly saturated. Growth is flat to negative, seriously impacting service provider profits. Tough economic times only amplify this situation. To maneuver in this business climate, service provider´s must reinvent their business models by offering new, profitable, next-generation managed services, such as web-based video conferencing and collaboration, and other unified communications solutions. For this reason, is necessary to transform current OSS/BSS (Operations Support Systems / Business Support Systems) to new models based on the best practices, or new growing technology approaches, which bears potential of new revenues to service providers. Next generation managed services also offer the potential for rapid returns on investments.

  • Annotation:
    This paper deals with speech signal spoken by speaker under psychological stress. The investigation of speaker's stress is based on specific changes in short-time spectrum of vowel phonemes. For each selected signal segment, the spectrum was computed by means of two different approaches: Fourier transform and chirp transform. Comparative results between both spectra served for speaker's stress identification. In case of speech under stress, the obtained spectra differ towards the higher frequencies due to enhanced pitch modulation observed in the envelope of the chirp spectrum. For use in our experiments, a new database of speech under stress consisting of data collected during oral examinations at our university was created.

Statistical Analysis of Glottal Pulses in Speech Under Psychological Stress

  • Annotation:
    In this paper, the problem of speech signal under psychological stress is addressed. The investigation into the speaker's stress is based on statistical analysis of glottal pulse derivative extracted from the vowel signals. A pitch synchronous selection of segments from the glottal pulse waveform is used. Selected segments are fixed in their maxima and overlaid. The generated distribution matrix is analysed using special cuts. A new database of speech under stress is created for use in our experiments consisting of data collected during oral final examinations at our university. The database contains read and conversational speech of 31 male speakers, both in neutral and in stressed state. The stress recognition rate in the speaker dependent binomial classification (stress/no stress) reaches 88%.
