Population dynamics and ecology of subdominant phytoplankton species in a shallow hypertrophic lake (Albufera of Valencia, Spain)

1994

Long-term population dynamics and ecology of the abundant but non-dominant phytoplankton species of the shallow hypertrophic lake the Albufera of Valencia (Spain) are described for the period 1980–1988. The lake is used as a reservoir for the surrounding ricefield cultivation. It is continuously dominated by three filamentous blue-green algae, Planktothrix agardhii, Pseudanabaena galeata and Geitlerinema sp. Horizontal differences of the phytoplankton were less important than annual and seasonal variations. An annual increasing trend was observed for Planktolyngbya subtilis, Planktolyngbya contorta, Cylindrospermopsis raciborskii, Microcystis incerta, Nitzschia palea var. tenuirostris and R…

Scene giudiziarie nelle tragedie e nelle commedie latine del XII e XIII secolo. Il «De Affra et Flavio», il «De Paulino et Polla» di Riccardo da Veno…

2021

La commedia elegiaca e la tragedia latina del XII e XIII secolo mostrano una larga e varia ricchezza di caratteristiche, temi, soggetti e tipologie letterarie: uso del distico elegiaco, "imitatio" ovidiana, preponderanza della tematica amorosa, compresenza di narrazione e dialogo, e così via. Un elemento caratterizzante di alcune di queste commedie e tragedie medievali è rappresentato dalle scene giudiziarie. In questo saggio, dopo una breve introduzione sul genere letterario, viene svolta una puntuale analisi delle scene di giudizio che ricorrono in tre testi latini del XII e XIII secolo, una tragedia (l’anonimo «De Affra et Flavio»), una commedia elegiaca (il «De Paulino et Polla» di Ricc…

An evaluation of recent local image descriptors for real-world applications of image matching

2019

This paper discusses and compares the best and most recent local descriptors, evaluating them on increasingly complex image matching tasks, encompassing planar and non-planar scenarios under severe viewpoint changes. This evaluation, aimed at assessing descriptor suitability for real-world applications, leverages the concept of approximated overlap error as a means to naturally extend to non-planar scenes the standard metric used for planar scenes. According to the evaluation results, most descriptors exhibit a gradual performance degradation in the transition from planar to non-planar scenes. The best descriptors are those capable of capturing well not only the local image context, but als…

Midground Object Detection in Real World Video Scenes,

2007

Traditional video scene analysis depends on accurate background modeling to identify salient foreground objects. However, in many important surveillance applications, saliency is defined by the appearance of a new non-ephemeral object that is between the foreground and background. This midground realm is defined by a temporal window following the object's appearance; but it also depends on adaptive background modeling to allow detection with scene variations (e.g., occlusion, small illumination changes). The human visual system is ill-suited for midground detection. For example, when surveying a busy airline terminal, it is difficult (but important) to detect an unattended bag which appears…

Il presepe di Andrea Tipa nel Monastero de las Salesas Reales di Madrid

2022

The essay studies the nativity scene in coral, ivory and precious materials in the Monasterio de las Salesas Reales in Madrid, made by Andrea Tipa in 1749, the only work known to date to bear the signature of the master from Trapani. The Madrid nativity scene is contextualised with the production so far attributed to Andrea and the Tipa family and its exhibition history and restoration are reconstructed.

L’intermezzo, Napoli e l’Europa

2018

The essay is an attempt to summarize the most up-to-date knowledge related to the history of the comic intermezzo. Some crucial examples of the Neapolitan scenic tradition are analyzed in order to highlight the progressive emancipation of comic scenes. An examination of the main dramatic and musical characteristics of the genre follows. The last part of the article concerns the European circulation of the Italian creations, with special attention to the famous "querelle des bouffons", which broke out in the mid-eighteenth century Paris following the performance of Giovambattista Pergolesi's "La serva padrona".

Implementing Immersive Clustering with VR Juggler

2005

Continuous, rapid improvements in commodity hardware have allowed users of immersive visualization to employ high-quality graphics hardware, high-speed processors, and significant amounts of memory for much lower costs than would be possible with high-end, shared memory computers traditionally used for such purposes. Mimicking the features of a single shared memory computer requires that the commodity computers act in concert—namely, as a tightly synchronized cluster. In this paper, we describe the clustering infrastructure of VR Juggler that enables the use of distributed and clustered computers for the display of immersive virtual environments. We discuss each of the potential ways to syn…

The CSI-education effect: Do potential criminals benefit from forensic TV series?

2018

Abstract Forensic series have become popular over the last two decades. They have raised the importance of forensic evidence in the eyes of the public (CSI effect). However, it has not been investigated to what extent criminals may learn about forensic evidence through these shows. We used multiple approaches to tackle this potential CSI-education effect. First, we analyzed crime statistics for crime and detection rate. Second, we asked convicted criminals about their impressions about the usefulness of crime shows for covering up a crime. Third, we asked fans of crime series and a control group of non-watchers to slip into the role of a criminal by enacting the cleaning up a murder crime s…
