Bureaucrats in the government sector have a double role since they are both suppliers and demanders of public employment; they are publicly employed (supply labor) and they have an important say in deciding the size of the municipal employment (demand labor). In this paper we present and...

This paper discusses first results of a comparative study of different environmental policy instruments. In a model with pollution as a side effect of consumption different environmental policies are studied. In simulations we observe the dynamic behavior of models with utility functions of the...

During the operation of proton exchange membrane (PEM) fuel cell, water is easy to accumulate in the anode side, particularly if the fuel cell system is being controlled in ‘dead ended’ mode. The hydrogen purge operation prevents the anode being jammed by excessive water. It is observed that...

Microgrids are LV or MV electric networks which utilize various distributed generators (DG) to serve local loads. In this paper, dynamic models of the main distributed generators including photovoltaic (PV) cell, wind turbine, hydro turbine as well as the equivalent power electronic interfaces,...

The industrial waste heat parameters, like flow rate and temperature, usually fluctuate in a certain range due to the variation of upstream industrial process. However, the heat recovery systems are usually designed not under the fluctuation range but under a specific point, therefore, the most...
