We present a model for scheduling power generation at a wind farm, and introduce a particle swarm optimization algorithm with a small world network structure to solve the model. The solution generated by the algorithm defines the operational status of wind turbines for a scheduling horizon selected by a decision maker. Different operational scenarios are constructed based on time series data of...

Introducing object-oriented programming to old-style programmers is a rather hard task. This paper shows how this job was done at BMD Steyr, Austrians leading producer of accountancy software. A special course for former Cobol programmers was offered. This course is based on the principle that one should first learn data abstraction before one starts with object-oriented programming. Its struct...

This paper examines the cost efficiency of dairy farms in 2 important regions of commercial milk production in Poland (i.e., Wielkopolskie and Podlaskie). Both regions gained importance following the market-driven resource allocation mechanism adopted after Poland's transition to the market economy in 1989 and accession to the European Union (EU) in 2004. The elimination of the dairy quota syst...
