This paper concerns a Wizard of Oz (WoZ) method applied to a PDA applications domain speech interface design. Below, we define rules for selecting common PDA relevant functions, design them using SUEDE tool, and conduct WoZ experiments. Preliminary results show approximately 80 percent of user satisfaction in average.

Nowadays, electric power systems have been often operated close to their limits due to increased electric power consumptions, vast installments of renewable power sources and deliberated power market policies. This poses a serious threat to stable network operation and control. Therefore, voltage stability is currently one of key topics worldwide for preventing related black-out and islanding scenarios. In this paper, modelling and simulations of steady-state voltage stability problems in MATLAB environment are performed using author-developed computational tool implementing both conventional and more advanced numerical approaches. Their performance is compared with Simulink-based library Power System Analysis Toolbox (PSAT) in terms of solution accuracy, CPU time, and possible limitations. Their use for both real-time and off-line monitoring and assessment of system's voltage stability are also discussed.

This paper concerns development towards a method for measuring values of radiant norm around humans' head. This norm is important for radiant heating and thermal comfort in the sense of avoiding headaches and overheating as a result of a long-term heat exposure
