Investigation of modern oil paints through a physico-chemical integrated approach. Emblematic cases from Valencia, Spain
2020
Abstract The study and the characterisation of modern and contemporary oil paintings is still a challenging issue, in particular considering the significant changes in paint production across the 19th and 20th centuries. This paper presents the results of the first physico-chemical integrated study of the artistic materials used in six paintings from the School of Art and Higher Design of Valencia (Escola d'Art i Superior de Disseny, EASD-Valencia), artworks created between 1871 and 1943 by four famous Valencian artists: Salustiano Asenso Arozarena, Salvador Abril I Blasco, Enrique Navas Escuriet and Jose Bellver Delmas. A wide range of inorganic and organic compounds was identified through…
Performance Analysis of M-DPSK Modulation over Fast-Hoyt Fading Channels under Non-Isotropic Scattering Conditions
2021
In this paper, we analyze the symbol error probability (SEP) performance of M-ary differential phase shift keying (M-DPSK) modulation schemes over frequency-flat fast-varying Hoyt multipath fading channels. Assuming general non-isotropic scattering conditions, we first derive a finite-range integral expression for the probability density function (PDF) of the phase difference between two non-isotropic Hoyt vectors perturbed by additive white Gaussian noise (AWGN). Based upon the theory of M-DPSK modulation and the obtained PDF formula, the SEP of M-DPSK and its corresponding asymptotic behavior in non-isotropic fast-Hoyt fading channels are derived. Specifically, a double semi-finite range …
Important varieties of Sicily
2012
Sicily is an island to the south and west of Italy that is close to the “toe of the boot”, in the Mediterranean Sea. Its physical characteristics are representative of the Mediterranean region with its mountainous terrain and volcanoes, rugged coast, numerous beaches and blue water, scenic villages, and a diverse agriculture including wine grapes, citrus, olives, herbs, grains and seasonal vegetables. The climate is warm to hot, and the growing season is long. Located at the 36-38 degree latitude, Sicily is only about 160 kilometers (100 miles) from the north coast of Africa near Tunisia. It is also the midpoint east and west in the Mediterranean Sea. Through history the region was controll…
Development and application of a new Edible Coating on fruits and fresh-cut fruits.
2014
Il progetto di ricerca ha come scopo il miglioramento della gestione post-raccolta dei frutti (interi e di IV gamma), intervenendo sull’estensione della shelf-life; valutando l’utilizzo di composti provenienti da materiali di scarto delle filiere produttive agroalimentari o risorse alternative da utilizzare come nuovi rivestimenti commestibili (edible coating: EC). La novità riguarda lo sviluppo di un edible coating a partire da residui vegetali di Posidonia oceanica, pianta acquatica mediterranea ampiamente diffusa sulle coste siciliane, responsabile di accumulo di biomassa sulle spiagge. Per soddisfare, in maniera efficace, l’obiettivo iniziale si vorrebbe creare una interazione tra 1-MCP…
A strategy for the identification of building structures under base excitations
2008
In this paper the evolution of a time domain dynamic identification technique based on a statistical moment approach is presented. This technique is usable in the case of structures under base random excitations in the linear state and in the non linear one. By applying Itoˆ stochastic calculus special algebraic equations can be obtained depending on the statistical moments of the response of the system to be identified. Such equations can be used for the dynamic identification of the mechanical parameters and of the input. The above equations, differently from many techniques in the literature, show the possibility to obtain the identification of the dissipation characteristics independent…

AG FRONZONI,一個字母片段包含整個世界 / AG FRONZONI, a fragment of letter contains the whole world
2009
AG Fronzoni總是從牛群中走出來，作為一個巨大的鯨類，他獨自穿越海洋，就像一個想要測試自己能力的孤獨探險家，他知道首先他可以依靠自己的勇氣，除了必要的設備。同樣，他經歷了無盡而冰冷的冰川，在那裡，他已經學會瞭如何認識如此多的白色色調，並以不同的方式命名每一個，或者包含所有顏色的黑色。整個黑色作為夜晚的落下，無法吞噬每一個元素，包括那個向上彎曲的白色擴散溶解每一個突破，與極地天空變得一模一樣，白色像同樣的冰凍表面，漂白黑夜，深褐色至淺灰色，暫時取消其記憶。從來沒有看到絕對勝利者的驚人決鬥再次以這種方式形成，黑色和白色像古代的對手一樣彼此面對，意識到他們可以互相傷害死亡，但他們不能沒有另外，在反對派中很好地描述了與光明和黑暗交替有關的一個主要謎團。 A G Fronzoni has always swum away from the herd, as an enormous cetacean he has crossed alone the oceans, like a solitary explorer who wants to put his capabilities to test , and he knows that first of all he can count on his own courage, in addition to the essential equipment. The same he has gone through the endless and livid glaciers, where like the esquimese peo…
MARINA DEL CINQUE，花邊和字母刺繡 / MARINA DEL CINQUE, lacework and embroidery of letters
2009
平面設計師Marina del Cinque的名片呈現了一個大拳擊M，如果舉起來，它會成為一個小門戶，我們被邀請去探索她的世界。一個世界的圖形統治無可爭議，並在所有事物上留下了它的標誌，不僅顯然在她的作品上，而且在她的私人空間，她的日常激情以及她的生活方式和看待生活。從學習年代到自由職業的兩位大師長期陪伴她的教誨都存在於她身上。第一個是Germano Facetti，她在她的故鄉Genova遇見，當時她正在Istituto Politecnico di Design學習，這是一個由優秀教師組成的小型圖形學校，現在已經不存在了。他傳遞給了她，或者更好的是，當她強調對圖形和字母的熱愛時，他安裝在她身上。第二位大師是Italo Lupi，這位圖形建築師與她建立了一種基於高度尊重和選擇性親和力的關係。她與他合作了十年，只是在短時間內打斷她搬到倫敦為Pentagram工作室工作。 Lupi傳達了她對這些信件的熱愛，這些信件是人們所擁有的，並讓她發現美麗和色彩感，對於那些忠於反對者和完全清晰的黑白分明的她來說。 The visiting card of the graphic designer Marina del Cinque, presents a big punched M, which if lifted up becomes a little portal beyond which we are invited to go to discover her world. A world over wich graphics reigns undisputed and leaves…
Pensare in bianco. Progettare in bianco
2018
A partire da tre esempi di architetture bianche contemporanee, il contributo ne propone una lettura di continuità con la tradizione mediterranea e con la più recente eredità dell’architettura moderna. Emergono alcuni elementi comuni tra le opere, sintomatici di una più ampia tendenza contemporanea che mira al recupero dei caratteri della mediterraneità.
Warm white LED light by frequency down- conversion of mixed perylene-based dyes
2013
The growing demand of the solid-state lighting market for the development of sources for illumination has led to the fabrication of the first white LED in 1997, which employed a blue LED coated by a Ce:YAG phosphor to mix the down-converted yellow light with the blue one. The white light appears cold due to the weakness of red components in the emission spectrum. In order to obtain a warmer white, one possible solution is to add a red phosphor to the yellow one to move the chromatic coordinates properly, though the luminous efficiency drastically decreases due to the increased light absorption of the coating layer. It is generally believed that the low efficacy of warm white LEDs is the mai…
