Past forward. Chongqing, Shanghai and other italian urban stories
No full textThis book is born from the will to undertake a joint research path on the general theme of transformation and renewal of urban contexts, deepening the case of historical Chinese and Italian cities. The research collected case studies and theoretical elaborations, focusing on the Chinese city of Shanghai and Chongqing and other Italian urban realities, filtering contents around thematic nodes such as memory, narration and reflection on new urban models. In particular, the initial idea emerged from shared reflections between Chinese and Italian scientific professors responsible for international agreements established between the Department of Architecture and the Design of Sapienza University of Rome and Chinese remarkable institutions. Indeed, the present research, promoted and directed by Dina Nencini, was joined by Anna Irene Del Monaco of Sapienza and Shaoming Lu of Shanghai Jiaotong University.
The book directly and indirectly draws on a series of questions about the “memory work” walking a theoretical path which has a relevant milestone in Lieu de memorie (Pierre Nora 1984) and the 1996 Trienniale di Milano entitled “Identità, differenze: Triennale di Milano, XIX Esposizione internazionale: integrazione e pluralità nelle forme del nostro tempo : le culture tra effimero e duraturo” (Identity, Differences: Triennale of Milan, XIX International Exposition: Integration and plurality in the forms of our time: cultures between ephemeral and enduring)
Chinese and Italian cities “at work” on memory and imagination
No full textThis book is born from the will to undertake a joint research path on the general theme of transformation and renewal of urban contexts, deepening the case of historical Chinese and Italian cities. The research collected case studies and theoretical elaborations, focusing on the Chinese city of Shanghai and Chongqing and other Italian urban realities, filtering contents around thematic nodes such as memory, narration and reflection on new urban models. In particular, the initial idea emerged from shared reflections between Chinese and Italian scientific professors responsible for international agreements established between the Department of Architecture and the Design of Sapienza University of Rome and Chinese remarkable institutions. Indeed, the present research, promoted and directed by Dina Nencini, was joined by Anna Irene Del Monaco of Sapienza and Shaoming Lu of Shanghai Jiaotong University. All they, in turn, have involved other scholars already engaged in their previous and current studies on akin research issues and active in teaching and researching at University of Shanghai Jiao Tong University, Tsinghua University in Beijing, University of Chongqing, University of Naples Federico II, IUAV University of Venice and Polytechnic of Milan.
The book directly and indirectly draws on a series of questions about the “memory work” walking a theoretical path which has a relevant milestone in Lieu de memorie (Pierre Nora 1984) and the 1996 Trienniale
di Milano entitled “Identità, differenze: Triennale di Milano, XIX Esposizione internazionale: integrazione e pluralità nelle forme del nostro tempo: le culture tra effimero e duraturo” (Identity, Differences: Triennale of Milan, XIX International Exposition: Integration and plurality in the forms of our time: cultures between ephemeral and enduring). Particularly, the exhibition was conceived within the framework of a conceptual pendulum, the postmodernism of Jean-François Lyotard’s wishing to leave universal values and the Paul Ricoeur’s hermeneutic narrative, in bringing towards the mimesis the three following categories: prefiguration, configuration, reflection.1 And observing that “The inhabitant, like the reader, welcomes the building with its expectations, resistances and controversies”. Ricoeur’s interests are concentrated also on the concepts of architecture and narratives supporting also the idea that “to design architecture is like to work with memory since a built space is a condensed time.”2 Then, along the almost twenty-years-long conceptual path, the “memory work” in architecture has developed from removing modernity to absorbing modernity. The latest one, absorbing modernity, was the conceptual approach proposed by Cino Zucchi in the Italian Pavilion of the Venice Biennale of 2014 entitled “Innesti/Grafting”. Therefore, within a kaleidoscopic framework, the book highlights differences and analogies on seven emerging issues grounded on the research work of
Italian and Chinese scholars combined in pairs. Providing evidence of the comparative methodological approach is the most original purpose this volume intends to pursue. Also because it reveals the different challenges and possible overlapping areas of interests within two different architectural and urban cultural domain. Hence, the book collects essays by Chinese and Italian scholars in pair, as it is evident in the index structure, endowing analogies and complementarities, and bringing together theoretical studies and on-field case studies

No full textKhat consumption: a pharmacological review.
No full textThe present review deals with the considerable body of evidence gathered in the last ten years on the clinical and experimental pharmacology of Khat. Khat effects are generally agreed to be of amphetamine-like type. In particular, Khat ingestion, like amphetamine ingestion, produces sympathetic activation, anorexia, euphoria, increased intellectual efficiency and alertness. These effects are mainly mediated by phenylalkylamines, such as cathinone and cathine, because the pharmacological actions of these agents and those produced by amphetamine almost overlap. In infra-human species cathinone is an effective positive reinforcer (i.e., it maintains self-administration). However, it would be inappropriate to infer from cathinone and cathine effects assessed in animals a high potential of abuse for Khat in humans; apart from other reasons the bulk volume of Khat leaves, limits the ingestion of high quantities of the active principles. Accordingly, in habitual consumers Khat dependence is probably mild, because craving and tolerance to the sympathomimetic and neuroendocrine effects of Khat are present, but there is no definite abstinence syndrome. Therefore, in our opinion, policies restricting the use of Khat should be adopted with caution, lest they simply change the pattern of drug abuse and increase the spread of more dangerous drugs
Hypercomplex Quality Assessment of Multi/Hyperspectral Images
No full textThis letter presents a novel image quality index which extends the Universal Image Quality Index for monochrome images to multispectral and hyperspectral images through hypercomplex numbers. The proposed index is based on the computation of the hypercomplex correlation coefficient between the reference and tested images, which jointly measures spectral and spatial distortions. Experimental results, both from true and simulated images, are presented on spaceborne and airborne visible/infrared images. The results prove accurate measurements of inter- and intraband distortions even when anomalous pixel values are concentrated on few bands
Fusion of Panchromatic and Multispectral Images by Genetic Algorithms
No full textPan-sharpened MS is a fusion product in which the multispectral (MS) bands are spatially enhanced by the higher-resolution panchromatic (Pan) image. Most effective algorithms for pan-sharpening are based on multiresolution analysis (MRA), e.g., wavelets, Laplacian pyramids, wavelet frames, or curvelets. MRA approaches present one main critical point: filtering operations may produce ringing artifacts when high frequency details are extracted from the panchromatic image. In this paper, a pan-sharpening algorithm for 4-band MS data is proposed, which is not based on MRA, but it applies a Generalized Intensity-Hue-Saturation (GIHS) transformation to the MS bands. A genetic algorithm is adopted to define the injection model which establishes how the missing highpass information is extracted from the Pan image. The fitness function of the genetic algorithm which provides the algorithm parameters driving the fusion process is based on a quality index specifically designed for quality assessment of,4-band MS images. Both visual and objective comparisons with advanced fusion methods are presented on QuickBird image data
