Control of a PTZ camera in a hybrid vision system
2014
In this paper, we propose a new approach to steer a PTZ camera in the direction of a detected object visible from another fixed camera equipped with a fisheye lens. This heterogeneous association of two cameras having different characteristics is called a hybrid stereo-vision system. The presented method employs epipolar geometry in a smart way in order to reduce the range of search of the desired region of interest. Furthermore, we proposed a target recognition method designed to cope with the illumination problems, the distortion of the omnidirectional image and the inherent dissimilarity of resolution and color responses between both cameras. Experimental results with synthetic and real …

Anti-inflammatory Effects of South American Tanacetum vulgare
1998
Abstract In recent years the role of phenolic compounds and sesquiterpene lactones, particularly parthenolide, in the anti-migraine and anti-inflammatory effects of Tanacetum parthenium (Asteraceae) has attracted much attention. However, the closely-related cosmopolitan species T. vulgare has remained outside the mainstream of research in this field. After treating the aerial parts of T. vulgare with dichloromethane and methanol, and applying conventional column and thin-layer chromatographic techniques, it was possible to isolate from the moderately lipophilic fractions the principles responsible for the anti-inflammatory activity of this plant against the mouse-ear oedema induced by 12-O-…
Smart camera design for intensive embedded computing
2005
Computer-assisted vision plays an important role in our society, in various fields such as personal and goods safety, industrial production, telecommunications, robotics, etc. However, technical developments are still rare and slowed down by various factors linked to sensor cost, lack of system flexibility, difficulty of rapidly developing complex and robust applications, and lack of interaction among these systems themselves, or with their environment. This paper describes our proposal for a smart camera with real-time video processing capabilities. A CMOS sensor, processor and, reconfigurable unit associated in the same chip will allow scalability, flexibility, and high performance.
Investigating Limits in Exploiting Assembled Landslide Inventories for Calibrating Regional Susceptibility Models: A Test in Volcanic Areas of El Sal…
2022
This research is focused on the evaluation of the reliability of regional landslide susceptibility models obtained by exploiting inhomogeneous (for quality, resolution and/or triggering related type and intensity) collected inventories for calibration. At a large-scale glance, merging more inventories can result in well-performing models hiding potential strong predictive deficiencies. An example of the limits that such kinds of models can display is given by a landslide susceptibility study, which was carried out for a large sector of the coastal area of El Salvador, where an apparently well-performing regional model (AUC = 0.87) was obtained by regressing a dataset through multivariate ad…

New York City, la più grande città del cibo italiano
2021
This work offers an analysis of Italian restaurants in New York City. Historical literature and anthropological has repeatedly highlighted the role that Italian emigration to the east coast plays of the United States and the spread of gastronomic clothes marked as Italian in foreign territory they had in the construction of a tricolor gastronomic effigy (in part. Montanari 2010; Cinotto 2001; Cecla 1998). This interdependence strengthens the relationship from a semiotic perspective with otherness as an indispensable condition for building an indigenous food identity and food stereotypies recognized as "typical". Tricolor food symbols such as pasta and pizza owe their nationalization, for th…
Frank W. Taussig and Carl S. Joslyn on the Social Origins of American Business Leaders: A Chapter in the History of Social Science at Harvard
2019
In their 1932 volume "American Business Leaders: A Study in Social Origins and Social Stratification," Frank W. Taussig and Carl S Joslyn, then a young Harvard graduate, argued that success in business depended more on innate superiority than on other environmental factors such as financial aid, influential connections, and formal education. The aim of this paper is to analyze the main contentions of Taussig and Joslyn, as well the intellectual genesis of, and the general reactions to, this controversial volume. Although our main focus is on Taussig and Joslyn, other figures, all directly affiliated with Harvard, will play a decisive role in our narrative—the economist Thomas Nixon Carver, …
Chromatographically separable rotamers of an unhindered amide
2014
Surprisingly stable formamide rotamers were encountered in the tetrahydroisoquinoline and morphinan series of alkaloids. We investigated the hindered rotation around the amide bond by dynamic high-performance liquid chromatography (DHPLC) and kinetic measurements of the interconversion of the rotamers which can readily be separated by HPLC as well as TLC. The experimental results of the different methods were compared to each other as well as to results obtained by DFT calculations.
Agreement on the Choice of Non-applicable Law or Law not in Accordance with Article 22(1) of the Twin Regulations: what Consequences for the Couple’s…
2021
Los Reglamentos (UE) 2016/1103 y 2016/1104 del Consejo autorizan a las parejas transfronterizas a elegir la ley aplicable a sus relaciones patrimoniales sobre la base de uno de los criterios enumerados en el artículo 22.1. Sin embargo, el acuerdo de elección de la ley puede tener un contenido diferente al señalado en la redacción del artículo 22 de los ?Reglamentos Gemelos?. El objetivo del análisis es ilustrar que sería incorrecto sostener que tales acuerdos son, a priori, inválidos o no permiten la autonomía de la voluntad. Esta cuestión requiere una evaluación de la finalidad concreta del acuerdo de las partes y debería, al menos, estar abierta al examen del tribunal competente.
