Corrigendum to ‘An urban climate assessment and management tool for combined heat and air quality judgements at neighbourhood scale’
No full textThe authors regret that erroneously Sytse Koopmans MSc, was not listed as co-author in the original paper. Sytse Koopmans has introduced the LCZ-control in Figure 1, and performed the WRF runs presented in Fig 3. These model runs are also the basis for the analysis of Fig. 5 and the further development of the urban climate assessment and management tool. Therefore we would like to add him as co-author to this paper. The authors would like to apologise for any inconvenience caused
Automatische Emotionserkennung – Technologien, Deutung und Anwendungen
No full textMenschen kommunizieren nicht nur durch Sprache miteinander, sondern geben unbewusst auch eine Menge Informationen durch Emotionen preis. Da die herkömmliche Kommunikation zwischen Mensch und Computer oft nicht sehr intuitiv ist, soll sie durch die Entwicklungen im Forschungsbereich Affective Computing verbessert werden. Hierfür muss der Computer in der Lage sein, die Gefühle seines Gegenübers richtig zu deuten.In diesem Artikel werden die Technologien und Verfahren zur Erkennung menschlicher Emotionen von Computersystemen vorgestellt, die Deutung der Daten zu Emotionen beschrieben und Anwendungsbeispiele gezeigt. Der Schwerpunkt liegt bei den technischen Komponenten der Emotionserkennung. Hierbei steht die Deutung von Gesichtszügen, Aussprache und Vitaldaten (Puls, Blutdruck etc.) im Vordergrund. Andere Hinweise wie Gestik und Körperhaltung sind sehr schwer durch Sensorik zu messen bzw. kaum zu interpretieren. Die zuverlässigsten Ergebnisse liefern stets multimodale Verfahren, bei denen mehrere Sensoren als Quellen verwendet werden, um eine besser Zuordnung zu einem emotionalen Zustand zu ermöglichen. Dies spiegelt auch die menschliche Wahrnehmung wider, da wir Emotionen über eine Vielzahl von Sinnesorganen wahrnehmen

No full textOf the various media vehicles available for advertising, the internet is the latest and the most rapidly growing, emerging as the ideal medium to promote products and services in the global market. In this article, the authors propose an internet media planning model whose main objective is to help advertisers determine the return they obtain from spending on internet advertising. Using available data such as internet page view and advertising performance data, the model contributes to attempts not only to optimize the internet advertising schedule but also to fix the right price for internet advertisements on the basis of the characteristics of the exposure distribution of sites. The authors test the model with data provided by KoreanClick, a Korean market research company that specializes in internet audience measurement. The optimal durations for the subject sites provide some useful insights. The findings contrast with current web media planning practices, and the authors demonstrate the potential savings that could be achieved if their approach were applied.media planning; optimization; advertising repeat exposure; probability distribution; internet

Tissue engineering for total meniscal substitution : Animal study in sheep model
No full textObjective: The aim of the study was to investigate the use of a novel hyaluronic acid/polycaprolactone material for meniscal tissue engineering and to evaluate the tissue regeneration after the augmentation of the implant with expanded autologous chondrocytes. Two different surgical implantation techniques in a sheep model were evaluated. Methods: Twenty-four skeletally mature sheep were treated with total medial meniscus replacements, while two meniscectomies served as empty controls. The animals were divided into two groups: cell-free scaffold and scaffold seeded with autologous chondrocytes. Two different surgical techniques were compared: in 12 animals, the implant was sutured to the capsule and to the meniscal ligament; in the other 12 animals, also a transtibial fixation of the horns was used. The animals were euthanized after 4 months. The specimens were assessed by gross inspection and histology. Results: All implants showed excellent capsular ingrowth at the periphery. Macroscopically, no difference was observed between cell-seeded and cell-free groups. Better implant appearance and integrity was observed in the group without transosseous horns fixation. Using the latter implantation technique, lower joint degeneration was observed in the cell-seeded group with respect to cell-free implants. The histological analysis indicated cellular infiltration and vascularization throughout the implanted constructs. Cartilaginous tissue formation was significantly more frequent in the cell-seeded constructs. Conclusion: The current study supports the potential of a novel HYAFF/polycaprolactone scaffold for total meniscal substitution. Seeding of the scaffolds with autologous chondrocytes provides some benefit in the extent of fibrocartilaginous tissue repair
