Probabilistic analysis of truss structures with uncertain parameters (virtual distortion method approach)

2004

A new approach for probabilistic characterization of linear elastic redundant trusses with uncertainty on the various members subjected to deterministic loads acting on the nodes of the structure is presented. The method is based on the simple observation that variations of structural parameters are equivalent to superimposed strains on a reference structure depending on the axial forces on the elastic modulus of the original structure as well as on the uncertainty (virtual distortion method approach). Superposition principle may be applied to separate contribution to mechanical response due to external loads and parameter variations. Statically determinate trusses dealt with the proposed m…

Agro-food markets’ functional efficiency, products’ quality and information’s role

2018

Nowadays agro-food productions’ quality and markets’ economic efficiency are strictly connected and related to the increasing information’s role that is no doubt simplify by the global presence of the World Wide Web system. It is possible to assert that this kind of situation does not always safeguard information’s safety and propriety and at the same time consumers’ aware and complete choice capability. From a production markets’ economic efficiency point of view these elements contribute to create some kind of functional distortions able to prevent their proper working system under the economic theory profile and supply misunderstandings and informational asymmetries. These specific condi…

Dielectric and Elastic Parameters of LixNa1-xTa0.1Nb0.9O3 Ferroelectric Solid Solution Ceramics

2011

Results of the studies of electric and elastic parameters as functions of concentration in ferroelectric LiхNa1-хTa0.1Nb0.9O3 (x = 0–0.16) solid solutions and comparative studies of the elastic properties by acoustic and contact probe techniques are reported. The electric and elastic properties of LiхNa1-хTa0.1Nb0.9O3 solid solutions are shown to be rather sensitive to structural distortion at concentration-induced structural phase transitions. The values of elastic modules obtained from acoustic measurements are found to be in good agreement with those obtained by contact probe techniques.

ANALYSIS OF SUNSPOT NUMBER FLUCTUATIONS

2004

Monthly averages of the sunspot number visible on the sun, observed from 1749, Zurich Observatory, and from 1848 other observatories, have been analyzed. This time signal presents a frequency power spectra with a clear 1/fα behavior with α≃0.8±0.2. The well-known cycle of approximately 11 years, clearly present in the spectrum, does not produce a sensible distortion of that behavior. The eventual characterization of the sunspot time series as a fractal is analyzed by means of the detrended fluctuation analysis (DFA). The jump-size distribution of the signal is also studied.

Extraction of objects from structured backgrounds in the cat superior colliculus. Part II

1980

Specific changes occur in the cells of the uppers layers of the cat's superior colliculus when a two dimensional noise (background) is superimposed onto a deterministic signal (spot of light). Some of the measurements can be interpreted as meaning that some cells only react to certain relative movements of object (spot) and background (noise). The movement of the visual background is interpreted as environmental movement occurring due to the animal's own movement. The results of the measurements provide all the necessary presuppositions for a distinction between the animal's own velocity and that of the object (Part I). The experimental results can be interpreted with a model. The essential…

Evaluation of the orientation distribution of fibers from reflection images of fibrous samples

2014

We consider illumination systems and mathematical algorithms for determination of the anisotropy and topographical features of an illuminated surface from its reflection images. As a particular example we study determination of the fiber orientation of paper surface. We also consider illumination systems with multiple light sources, and introduce optimization algorithms that exploit different spectral bands of these light sources. We show that a system of three light sources, e.g., a blue, green and red LED placed in a regular triangular form, efficiently prevents distortion of the above features. It is also easy to implement in applications, e.g., of the paper industry. We furthermore show…

Tra Sicilia e America: gli “scappati” di Cosa Nostra,

2009

Territorial control is one of the most important elements for the survival of the mafia. It is an obligated path to be able to obtain and control economic activities and to penetrate into all profitable sectors. Without territorial control it is impossible to control voters and without it all relationships with politics wither and die. It is within the territory where the imposition of "pizzo" (protection money) and extortion are planned against businesses and firms. This impending presence is also the cause in which citizens and families find themselves submitted to violence, the abuse of power and, if not only, to a limitation to their sphere of action. Telling the story about the scappat…

A reexamination of voltage distortion for classical carrier-based vs B-Spline modulation of three-phase Voltage Sources Inverters

2015

Voltage waveform improvement has been the object of several investigations for many years and a manifold of different solutions have been proposed to reduce the harmonic content in Voltage Source Inverters (VSI) power application. In many cases this improvements have been obtained by modifying the reference voltage modulating signal. The recent introduction of cardinal B-spline functions, used as carrier signals, has given rise to a new modulation technique whose main characteristic is a lower value of the Total Harmonic Distortion (THD). After the discussion on the B-Spline modulation principle and on its computational effort, a performance comparisons is carried out by means of Total Harm…

El centro de producción de tapices de Tortosa (ca. 1425-1493/1513)

2007

[spa] Este artículo da noticia de la actividad del centro de producción de tapices de Tortosa entre 1425 y 1513; se documentan los maestros Pere Alfonso, Berenguer Baldrich, Joan Falsison, Jaume Sastre, Pere Marquès, Loor Batur, mestre Rubert y Joan Marroquí. Además, se proponen dos hipótesis principales: que en Tortosa se intentó poner en marcha una importante manufactura de tapices ("draps de Ras") hacia 1450, y que el citado Joan Falsison es el autor del tapiz de la Santa Cena de la catedral de Tortosa.
