We present the development of the UTP-Calculator: a tool, written in Haskell, that supports rapid prototyping of new theories in the Unifying Theories of Programming paradigm, by supporting an easy way to very quickly perform test calculations. The emphasis during the calculator development was keeping it simple but effective, and relying on the user to have the expertise to check its output. I...

Traffic noise pollution is a growing problem that highly affects the health of people. To cope with this problem one has to regulate traffic or construct noise barriers. In order to implement effective measures against traffic noise the information about its distribution – noise maps is imperative. This paper presents our work in creating a noise calculator software package implementation that ...

In two experiments, we studied how people's strategy choices emerge through an initial and then a more considered evaluation of available strategies. The experiments employed a computer-based paradigm where participants solved multiplication problems using mental and calculator solutions. In addition to recording responses and solution times, we gathered data on mouse cursor movements. Particip...
