Surface Reversal Method Algorithm Development

The reversal method introduced by previous research focuses in finding reference datum of topography data of cylinder end surface but somehow ignores the existence of error. This problem leads to the purpose in introducing an understanding of how this method can be improvised. Thus, in this paper, a primitive approach was done by introducing the algorithm of the surface reversal method and simulating the reversal method on a selected surface to test how it works. This paper used MATLAB software for the majority of data processing. It started by preparing two simulated surfaces which were surface A and surface B (180o rotation). Then, it continued with the preparation of surface by converting the surface data into an image file type which made surface A and surface B aligned in the same direction before conducting surface correlation and finally finding the best match point between both surfaces. These basic steps play an important role to ensure the whole procedure for the next future studies is accurate. The peak result at position (540 x 409) from surface correlation was able to ease the next procedure by having a proper position before doing surface subtraction. The algorithm developed through MATLAB has successfully demonstrated the primary steps of surface reversal method.

Amanti di vita, amanti di morte: la violenza relazionale che non finisce sui giornali

L'articolo analizza il fenomeno della violenza relazionale "sottile" nel rapporto uomo-donna, e gli irretimenti derivanti dalla violenza simbolica, sedimentati storicamente nella psiche femminile; tali irretimenti forniscono l'elemento inconscio di collusione che espone la donna a numerose violazioni dell'alterità nel rapporto con l'uomo. A tal fine, l'autrice propone l'interpretazione in chiave simbolica di un noto film del regista W. Allen, Match Point (2005), in cui è rappresentata una situazione di violenza estrema nei confronti di una figura femminile da parte del partner maschile che, a causa del reciproco coinvolgimento sentimentale, sente minacciato il proprio equilibrio narcisistico e la sua scalata sociale. Si prospetta, dunque, un tradimento dell'anima che, come afferma il filosofo francese Lévinas, si manifesta attraverso "il volto dell'altro". Queste storie che sembrano riguardare l'ambito esclusivamente privato dei rapporti tra uomini e donne, in realtà hanno una corrispondenza nell'ambito della vita pubblica degli esseri umani, nella polis, perché ciò che accadenella psiche degli individui, nelle loro relazioni personali, è sempre anche una questione politica.

Reducing Shadow Effects on the Co-Registration of Aerial Image Pairs

Image registration is an important preprocessing step prior to detecting changes using multi-temporal image data, which is increasingly accomplished using automated methods. In high spatial resolution imagery, shadows represent a major source of illumination variation, which can reduce the performance of automated registration routines. This study evaluates the statistical relationship between shadow presence and image registration accuracy, and whether masking and normalizing shadows leads to improved automatic registration results. Eighty-eight bitemporal aerial image pairs were co-registered using software called Scale Invariant Features Transform (<small>SIFT</small>) and Random Sample Consensus (<small>RANSAC</small>) Alignment (<small>SARA</small>). Co-registration accuracy was assessed at different levels of shadow coverage and shadow movement within the images. The primary outcomes of this study are (1) the amount of shadow in a multi-temporal image pair is correlated with the accuracy/success of automatic co-registration; (2) masking out shadows prior to match point select does not improve the success of image-to-image co-registration; and (3) normalizing or brightening shadows can help match point routines find more match points and therefore improve performance of automatic co-registration. Normalizing shadows via a standard linear correction provided the most reliable co-registration results in image pairs containing substantial amounts of relative shadow movement, but had minimal effect for pairs with stationary shadows.

Match point (Allen, 2005): a propósito del Tom Ripley de Patricia Highsmith

Reconocido como uno de los directores más prolíficos en los últimos 30 años, Woody Allen presentó en 2005 su película Match Point. La característica principal que la define es el comportamiento de su protagonista, Chris Wilton, un tenista retirado del circuito profesional que llega a Londres con grandes aspiraciones. Este personaje arribista y amoral parece surgido de las novelas de Patricia Highsmith, más en concreto de su más famoso personaje, Tom Ripley. Ambos protagonistas comparten nexos comunes: ambición, asesinatos, crímenes sin castigo, facilidad para adaptarse al medio, falta de moralidad... El objetivo del presente artículo es abordar los paralelismos y conexiones entre Match Point y El talento de Mr. Ripley (The talented Mr. Ripley, Highsmith, 1955), tanto en la novela como en sus adaptaciones cinematográficas, centrándonos principalmente en la película que Anthony Minghella presentó en 1999 bajo el título homónimo de la novela de Patricia Highsmith, destacando el uso de la música como recurso narrativo fundamental.
