The authors present a new concept of digital gastronomy—Cornucopia, a futuristic cooking methodology based on digital technologies. They discuss how they have merged kitchen tools with science fiction and actual technologies to create this new design space for gastronomy. The Virtuoso Mixer, the Digital Fabricator and the Robotic Chef were conceptualized to enable more flexibility and control over each of the most important elements of cooking: mixing ingredients, modeling food shapes and transforming edible matter from one state to another. The authors discuss related work and ideas, present their designs and propose their vision for the emerging design space of digital gastronomy.

The water resources quality continuous monitoring is a complex activity. It generates extensive databases with time series of many variables and monitoring points that require the application of statistical methods for the information extraction. The application of statistical methods for frequency analysis of time series is linked to attending of the basic assumptions of randomness, homogeneity, independence, and stationarity. However, despite its importance, the verification of these assumptions in water quality literature is unusual. Therefore, the present study tests the Upper Iguaçu basin water quality time series against the mentioned hypotheses. Rejection was observed in 15%, 26%, 51% e 31% for randomness, homogeneity, independence, and stationarity, respectively. The results evidenced the strong relation between monitoring strategy, data assessment and meeting of basic statistical assumptions for the analysis of water quality time series. Even with the existence of possible solutions for addressing those issues, the standard monitoring strategies, with irregular frequencies and lack of representativeness in relation to other periods, beyond commercial, act as an obstacle to their implementation.
