Process mining techniques are able to extract knowledge from event logs commonly available in today’s information systems. These techniques provide new means to discover, monitor, and improve processes in a variety of application domains. There are two main drivers for the growing interest in process mining. On the one hand, more and more events are being(More)
In this paper, we investigate the applicability of experimental model ecosystems (microcosms and mesocosms) for the ecological risk assessment of veterinary medicinal products (VMPs). VMPs are used in large quantities, but the assessment of associated risks to the environment is limited, although they are continually infused into the environment via a(More)
Many species produce alarm calls that vary according to situation. Theoretically, alarm call structure could covary with predator type and could communicate potentially “referential” information, or calls could covary with the degree of risk a caller experienced when it emitted a call. Using similar methods, I studied the ways in which Olympic (Marmota(More)
A quality cost analysis was performed with the cooperation of six full-time African catfish, Clorias gariepinus, farmers in The Netherlands. The relative distribution of the quality costs does not fit a common quality cost model. Possible explanations for this observation are the absence of (1) feedback from customers and (2) well-defined quality criteria.(More)
