A Tool for Predicting the Dynamic Response of Biotrickling Filters for VOC Removal

2016

This article presents the development of a MATLAB® computer program to simulate the performance of biotrickling filters. Since these filters behave differently during spraying and nonspraying cycles, the presented simulation tool is built on top of a mathematical description of each situation. The resulting variable-structure model is then used as the basis for simulation experiments. The model presented herein represents the first attempt to take into account the variable spraying pattern usually found in industrial installations. Overall, the software is flexible and easy to use, allowing the user to specify the emission concentration pattern, the gas concentration pattern, as well as the…

Mündliche Kompetenz und Bewusstsein beim unterrichtlichen Fremdsprachenlernen

2014

Das Buch befasst sich mit dem Zusammenspiel von kognitiven, emotionalen und motivationalen Faktoren beim Aufbau von mündlicher Kompetenz in Deutsch als Tertiärsprache bei erwachsenen Italienern. Es stützt sich dabei auf ein interdisziplinäres Vorgehen, das theoretisch erörtert und in seiner Methodenwahl ausführlich dargelegt wird, insbesondere die Videografie sowie intro-/retrospektive Verfahren. Die Ergebnisse der Studie veranschaulichen die Lernprozesse einmal klassenübergreifend, zum anderen erfolgt eine detaillierte Analyse der einzelnen Lernenden. Das Literaturverzeichnis liefert Lehrenden, Studierenden und Forschern eine erschöpfende bibliographische Quelle zu den behandelten Themen.

The Studio: Reflections and Issues Arising

1999

An advanced Telematic Studio was built at the University of Jyvaskyla to combine the latest technologies for local and distributed work and/or meetings. The objectives were to combine leading edge technologies with ethnographic design principles derived from CSCW and HCI to support a broad range of activities. We informed the design by studies of similar facilities on other sites. The Studio is popular, and it is easy to give glowing accounts of its use. Nevertheless, over three years a significant number of problems have arisen with both technologies and uses. Some of these are local. Others may be generalisable to any ‘cooperative building’. For example: problems with videoconferencing; i…

Autobiografia(e) in forma d’archivio. Giovanna Brogna/Sonnino tra iconotestualit  e libri d’artista

2021

Il contributo prende in esame l’attivit  poliedrica di Giovanna Brogna/Sonnino proponendo un confronto tra le differenti aree di ricerca (fotografia, cinema, arti visive) esplorate dall’artista che ama sconfinare tra tecniche e linguaggi spesso incrociati tra loro. L’analisi del libro d’artista Lettere al Dott. B. 1979-1987 (2019), raccolta di lettere battute a macchina indirizzate allo psicanalista di Brogna Sonnino e accompagnate da materiale eterogeneo (cartoline, fotografie, collage, fotocopie), offre l’occasione per ripercorrerne gli esordi da cineasta e l’approdo alle arti visive e di individuare alcune consonanze importanti fra i suoi diversi campi di ricerca: l’archivio come pratica…

<title>Real-time face tracking and recognition for video conferencing</title>

2001

This paper describes a system of vision in real time, allowing to detect automatically the faces presence, to localize and to follow them in video sequences. We verify also the faces identities. These processes are based by combining technique of image processing and methods of neural networks. The tracking is realized with a strategy of prediction-verification using the dynamic information of the detection. The system has been evaluated quantitatively on 8 video sequences. The robustness of the method has been tested on various lightings images. We present also the analysis of complexity of this algorithm in order to realize an implementation in real time on a FPGA based architecture.

A vision system for symbolic interpretation of dynamic scenes using arsom

2001

We describe an artificial high-level vision system for the symbolic interpretation of data coming from a video camera that acquires the image sequences of moving scenes. The system is based on ARSOM neural networks that learn to generate the perception-grounded predicates obtained by image sequences. The ARSOM neural networks also provide a three-dimensional estimation of the movements of the relevant objects in the scene. The vision system has been employed in two scenarios: the monitoring of a robotic arm suitable for space operations, and the surveillance of an electronic data processing (EDP) center.

A Review of Kernel Methods in Remote Sensing Data Analysis

2011

Kernel methods have proven effective in the analysis of images of the Earth acquired by airborne and satellite sensors. Kernel methods provide a consistent and well-founded theoretical framework for developing nonlinear techniques and have useful properties when dealing with low number of (potentially high dimensional) training samples, the presence of heterogenous multimodalities, and different noise sources in the data. These properties are particularly appropriate for remote sensing data analysis. In fact, kernel methods have improved results of parametric linear methods and neural networks in applications such as natural resource control, detection and monitoring of anthropic infrastruc…
