The language of gestures in some of El Greco's altarpieces
No full textThis study explores El Greco's language of gestures. The first part will explain the
preconditions for the general development towards rhetorical gestures and draw
parallels with El Greco's artistic development in the sphere of gestures. In addition,
handbooks on gestures are introduced. The second part will analyse how El Greco
applied gestures, using examples of his paintings .. It will reveal how El Greco
developed some gestures over more than thirty years, and how he creates with their
help an intense concentrated mood in his paintings. It will also demonstrate how he
worked by means of hyperbole to evoke an inspiring atmosphere, how he created
space with the help of gestures and gaze, and how he transformed the meaning of
some 'model' gestures he took over from famous Italian painters. Finally, this work
seeks to renew and intensify the analysis of gestures in painting as a way of
approaching the paintings and revealing layers of meaning that can not be found by an
analysis solely focused on iconographic topics. In this study the body is taken as a
mediator of signs, difficult to read, but decipherable. This study is intended to be a
step forward in approaching a deeper understanding of the codified language of
gesture. It should open the way to an intensified concern with the language of
gestures, with the reading of bodily signs in paintings
Chapter 7 - Compound-Gaussian Models and Target Detection: A Unified View
No full textAs a radar operates, it generally receives clutter returns from the environment that must
be distinguished from targets of interest. If one assumes that the clutter returns obey complex
multivariate Gaussian statistics, then a straightforward application of statistical detection theory
leads to an optimal detector in the form of the well-known matched filter (Chap. 2 of this book).
The occurrence of Gaussian statistics is often justified on the basis of the Central Limit Theorem
(CLT) applied to a phenomenological scattering picture that models the radar return as arising
from contributions of a large number of scatterers in the radar resolution cell. In this case, the
univariate intensity tail distribution is exponential. For early, low resolution radars, this model
was adequate
Analysis and Modeling of Echolocation Signals Emitted by Mediterranean Bottlenose Dolphins
No full text We analyzed the echolocation sounds emitted by Mediterranean bottlenose dolphins. We extracted the click trains by visual inspection of the data files recorded along the coast of the Tuscany with the collaboration of the CETUS Research Center. We modeled the extracted sonar clicks as Gaussian or exponential multicomponent signals, we estimated the characteristic parameters and compared the data with the reconstructed signals based on the estimates. Results about the estimation and the data fitting are largely shown in the paper.</p
