Acoustic emission detection of macro-cracks on engraving tool steel inserts during the injection molding cycle using PZT sensors

This paper presents an improved monitoring system for the failure detection ofen graving tool steel inserts during the injection molding cycle. This system uses acoustic emission PZT sensors mounted through acoustic waveguides on the engraving insert. We were thus able to clearly distinguish the defect through measured AE signals. Two engraving tool steel inserts were tested during the production of standard test specimens, each under the same processing conditions. By closely comparing the captured AE signals on both engraving inserts during the filling and packing stages, we were able to detect the presence of macro-cracks on one engraving insert. Gabor wavelet analysis was used for closer examination of the captured AE signalsć peak amplitudes during the filling and packing stages. The obtained results revealed that such a system could be used successfully as an improved tool for monitoring the integrity of an injection molding process

The discursive construction of class and lifestyle: Celebrity chef cookbooks in post-socialist Slovenia

This book discusses transformations in the construction of culinary taste, lifestyle and class through cookbook language style in post-socialist Slovenia. Using a critical discourse studies approach it demonstrates how the representation of culinary advice in standard and celebrity cookbooks has changed in recent decades as a result of general social transformations such as postmodernity and globalization. It argues that compared to the standard cookbooks, where nutritionist ideology is at the forefront, the celebrity cookbooks reflect the conversational, hybrid nature of the genre, through which they promote global foodie discourse, while at the same time localizing the global trends to the Slovene context. The book lays at the intersection of discourse analysis, sociology, food, cultural, communication and media studies and (post-) socialism and should be of interest to those interested in celebrities, food media, socialism and post-socialism, cookbooks, globalization and discourse change.https://benjamins.com/catalog/dapsac.75div_BaMpub4810pu
