Scalable video algorithms (SVAs) using the novel principle of priority processing guarantee real-time performance on programmable platforms, even with limited resources. Dynamic resource allocation is required to maximize the overall output quality of independent, competing priority processing algorithms that are executed on a shared platform. In this paper we describe the mapping of a priority processing application on the Cell/B.E. platform. We compare the performance of different implementations for dynamic-resource-allocation mechanisms, and show that priority processing achieves real-time performance.

If insects are detected they are compared with morphological data in store to decide if the detected individual is a target pest. In case a target pest is determined with high probability, a laser beam is directed to the target to eliminate the insect by heat. The concept is to develop a system that is able to learn and identify more and more different species over time. First aims of the project are to improve reliability of species detection and identification in contrast to the grain with different light spectra and camera parameters. Reaction tests under different light conditions of the two exemplary insects grain weevil Sitophilus granarius (Col., Curculionidae) and Indianmeal moth Plodia interpunctella (Lepid., Pyralidae) will be carried out. Further the project will investigate laser beam wavelengths and intensities not damaging surfaces and items beneath or next to targets. The system could be utilized to support IPM in well-sealed structures for storage or processing of food and feed stuffs.

Proceedings of the 8th Changeable, Agile, Reconfigurable and Virtual Production Conference (CARV2021) and the 10th World Mass Customization & Personalization Conference (MCPC2021), Aalborg, Denmark, October/November 2021 N2 - In the industry, connecting machines and tools - also known as the industrial Internet of things (IIoT) - is an essential part of the digital transformation of a company. The aim is to increase the efficiency and predictability of complex processes. In manual and semi-automatic processes, imaging sensors can help to monitor conditions, gives automated feedbacks to a central system, and e.g. provide current information for a digital twin. However, when imaging sensors are integrated into established IIoT platforms, they quickly reach their system limits due to the multidimensionality and high update and data rates. This paper presents a software platform that enables decoupled automated image processing through the abstraction and contextualization of the sensor technology and its data as well as a plugin architecture. Analogous to edge computing, partial processing can already be performed close to the sensor node to condensate data and reduce network loads and latencies. Thereby, all these approaches increase the longevity, flexibility and scalability of multi-sensor systems and associated processing algorithms. Based on the generic structure of the sensor network, the user is provided with an intuitive user interface that is based on IIoT platforms and enables the integration of their processing pipelines even for non-experts, despite the high complexity of the data.

However, the frequently application-oriented development of concepts and initial implementations make it difficult to adapt them to other applications. Especially when production deviates from the usual highly automated processes and requires high flexibility, e.g. to allow batch size one. In such a case, the Digital Twin must support modular shopfloors with flexible areas in which different production times and various tools and machines are used. It should also be possible to react promptly to problems in production. Design errors that only become apparent during production must be reported directly. In order to deal with this problem, the paper presents a concept for an abstract representation of a Digital Shadow (DS). The DS combines the disciplines of production planning and control, product lifecycle and layout planning which creates new links and enables further application scenarios. Based on this Digital Shadow, different applications can be realized that provide user-related solutions. For this purpose, a tree structure is used that links information about the product and the production environment which in this case is variable.

Zunächst wird ein Überblick über die Terminologie und Definitionen bezüglich der Sprechgeschwindigkeit gegeben. Ausgehend vom allgemeinen Kommunikationsbegriff werden neben der Sprachkommunikation insbesondere die temporalen Limitierungen der Sprachproduktion und Sprachperzeption erörtert. Die Grenzen der Wahrnehmbarkeit beschleunigter akustischer Sprache hängen unter anderem auch von der Sehfähigkeit des Hörers ab. Aus diesem Grund werden insbesondere bereits veröffentlichte und eigene Versuchsergebnisse mit sehbehinderten, blinden und sehenden Menschen präsentiert. Der Kernpunkt dieser Arbeit ist die instrumentelle Skalierung von Sprache. Neben dem historischen Rückblick werden aktuelle Skalierungsmethoden und -algorithmen betrachtet und eine mögliche Strategie zur Verbesserung der Verstehbarkeit und Verständlichkeit entwickelt. Hierbei wird Analyse, Segmentierung und Dezimierung des Sprachsignales zur Erhaltung der Echtzeitfähigkeit ausschließlich in der zeitlichen Domäne durchgeführt. Die neue Sprachskalierungsstrategie beinhaltet außerdem die Erhaltung aller Lautübergänge und führt zur ausschließlichen Reduktion der Phon-nukleus. Die relative Menge der eliminierten Signalanteile hängt von der Detektion einer stimmhaften, stimmlosen oder fehlenden Anregung ab. Mit den auditiven Experimenten werden zunächst die Wahrnehmungsfähigkeiten von sehenden, sehbehinderten und blinden Probanden bezüglich Verstehbarkeit und Verständlichkeit mit einem bereits bekannten linearen Skalierungsverfahren untersucht. Weitere instrumentelle und auditive Analysen dienen der Parameterevaluierung des in dieser Arbeit entwickelten Skalierungsverfahrens. Abschließend erfolgt die auditive Evaluierung des phonsegmentierenden, nichtlinearen Sprachskalierers mit aktuellen Skalierungsverfahren. Abschließend wird neben der zeitlichen Skalierung die Grundfrequenz in ihrer Dynamik bis zur Monotonie eingeschränkt. Hiermit soll untersucht werden, ob die Verringerung der Grundfrequenzdynamik eines beschleunigten Sprachsignals dessen Verstehbarkeit und Verständlichkeit erhöht.
