Behavioural and physiological changes during diapause, an important strategy of insects for surviving harsh seasonal conditions, have been intensively studied. The genetic and molecular mechanisms underpinning diapause development are less well known. We took a candidate gene approach to study prediapause gene expression patterns in the Colorado potato(More)
As the use of dynamic process simulation in industry has increased, a need has emerged for an easy way to configure reliable and powerful data exchange between simulation applications and distributed control systems (DCS's). A system where the control applications and man-machine interfaces of the real DCS are connected to a simulation model of the process,(More)
The use of simulation aids in the automation of industrial processes is not a new idea. Simulation facilitates the realization of engineering activities related with the installation and the optimization of those control systems in real plants. Nowadays the use of simulation aids is a simpler issue because of the characteristics of current process control(More)

This master's thesis is related to a research and development project that develops methods and tools for simulation assisted automation testing. The idea of simulation assisted automation testing is to connect the automation system to process simulator that produces a reliable process response. With this arrangement the automation system operates in a(More)
