We present a model for plant dispersal in agricultural landscapes to evaluate the gene dispersal from genetically modified (GM) plants. Dispersal from seed and pollen is modeled with partial differential equations. In scenarios, we investigated the effect of roadside application of non-selective herbicides on dispersal of herbicide tolerant oilseed rape (HT OSR). We showed that OSR growing on ...

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research several different reactor constructions and impeller configurations were modelled to achieve a better ...

Several undergraduate programs include the “Heat transfer” subject and, in our experience, it is hard for the students to grasp the concepts that are presented in the course. With this in mind, we designed and constructed an apparatus for the experimentation of heat transfer in a short bar. It was observed, that the time required to perform the experiment was so long, that the didactic aim ...

The paper presents the development of a method that determines building material and surface properties using relative simple and low-budget experiments, The method comprehends an optimal design of an experimental set up for smart determination of heat and moisture properties using both normal and inverse modeling techniques. It is concluded that the suggested methodology of the inverse ...

Kontinuierliche populationsdynamische Modelle lassen sich durch Systeme von gewöhnlichen Differentialgleichungen darstellen. Die räumliche Ausbreitung wird durch parabolische partielle Differentialgleichungen beschrieben, im einfachsten Fall durch eine Konvektions-Dispersionsgleichung. Für gekoppelte Populationen erhält man damit ein System von Reaktions-Diffusionsgleichungen mit erheblichen ...

FEMLAB has standard facilities to export models to Simulink. Normally, the standard export works well if the solvers, available in Simulink, can handle the problem. However, if a model in FEMLAB needs special solvers, for example airflow or other non-linear problems, the standard export to Simulink is often not suitable, because the standard solvers of Simulink cannot handle such a problem ...

As biologists uncover the structural and functional complexity of living organisms, it is increasingly clear that mathematical models are needed to synthesize experimental data and predict biological responses to external stimuli. Bioengineers are well-suited to develop such models and to add mechanics, fluid flow and other physical cues to the understanding of biological structure and ...

Acoustic vibrations are studied for several objects through the application of computational and optical diagnostic techniques. Computational studies are carried out using the eigenfrequency analysis option in the COMSOL structural mechanics application mode, whereas experimental optical studies utilize real-time stroboscopic holography. The two approaches provide complementary descriptions ...
