Directionlets: Anisotropic Multidirectional representation with separable filtering
2006
In spite of the success of the standard wavelet transform (WT) in image processing in recent years, the efficiency of its representation is limited by the spatial isotropy of its basis functions built in the horizontal and vertical directions. One-dimensional (1-D) discontinuities in images (edges and contours) that are very important elements in visual perception, intersect too many wavelet basis functions and lead to a nonsparse representation. To efficiently capture these anisotropic geometrical structures characterized by many more than the horizontal and vertical directions, a more complex multidirectional (M-DIR) and anisotropic transform is required. We present a new lattice-based pe…
G-CLASS: geosynchronous radar for water cycle science – orbit selection and system design
2019
The mission geosynchronous – continental land atmosphere sensing system (G-CLASS) is designed to study thediurnal water cycle, using geosynchronous radar. Although the water cycle is vital to human society, processes on timescalesless than a day are very poorly observed from space. G-CLASS, using C-band geosynchronous radar, could transform this. Itsscience objectives address intense storms and high resolution weather prediction, and significant diurnal processes such assnow melt and soil moisture change, with societal impacts including agriculture, water resource management, flooding, andlandslides. Secondary objectives relate to ground motion observations for earthquake, volcano, and subs…

Graphic analysis of geometric tiles patterns. The complex of Shaykh ‘Abd Al-Samad At Natanz
2020
The complex of ‘Abd al-Samid at Natanz, (end of the first decade of the 14th century) includes several buildings: a four-iwan mosque, an octagonal sanctuary, a minaret, and a mosque from the 1930s fronted by a fourteenth-century portal (pīshṭāq). The portal, the only remains of a khanqah, occupies the western end of the southern façade. It takes the form of an iwan, covered in a rich variety of patterns of colourful glazed tile and unglazed carved terracotta. It is adorned by a majestic muqarnas vault of six rows ending at the top with a starry motif. Each element that constitutes the muqarnas is also covered with tiles of different patterns that alternate, both in the main and in the conne…
Ode al libro
2011
La nascita di un libro, è sempre un momento felice, tale e tanta la fatica che richiede la costruzione di un oggetto tanto complesso, perfettamente a proprio agio nella dimensione bidimensionale e in quella tridimensionale, in entrambe delle quali vive la grafica editoriale. Il libro è figlio di un processo progettuale duplice perché volto alla costruzione del contenitore ma anche, come accade in questo caso, del suo prezioso contenuto. Il primo fatto di struttura, di materiali, di carte, di inchiostri, di formati, di piegature, di rilegature, di sedicesimi o di suoi multipli. Il secondo composto da quei materiali “semilavorati”, come i caratteri tipografici, le immagini, i disegni, i color…
Helicoid and Architectural application
2012
Questo articolo è un risultato parziale di una ricerca riguardante la rappresentazione di superfici complesse in geometria descrittiva. La padronanza e l’abilità nell’uso delle diverse tecniche di rappresentazione, consente di raggiungere risultati che altrimenti non sarebbero perseguibili. La Scuola di Disegno di Ingegneria, dell’Università di Palermo si è da sempre fatta promotrice della scienza della rappresentazione attraverso la sperimentazione di tecniche semplificative ed innovative della geometria descrittiva applicata all’architettura e all’ingegneria. In particolar modo, in questo lavoro, si riporta lo studio di una superficie complessa quale è l’elicoide che trova larga applicazi…
An Empirical Investigation of Green Product Design and Development Strategies for Eco Industries Using Kano Model and Fuzzy AHP
2022
Collaboration in green product design and development is becoming more significant to ensure a brighter future for eco industries, and research into such innovation has increased in recent years. So, it has been emphasized by practitioners that green thinking should be adopted from the design stage through the development stage and into the disposal stage of a product. However, it is challenging to identify the severity of strategies that mainly hampers the growth of green product design and development (GPDD). The current research aimed to identify and rank various strategies based on their significant impact on the development of green product design. The study contains three segments: (1…
Mining Customer Requirement from Helpful Online Reviews
2014
Today there are a huge quantity of online reviews available across different categories of products. The key question is how to select helpful online reviews and what can we learn from the abundant reviews. In this paper, we first conclude five categories of features to predict reviews' helpfulness from the perspective of a product designer and then present an approach based on conjoint analysis to measure customer requirement. The suggested approach are demonstrated using product data from a popular Chinese mobile phone market.
Una rigenerazione smart per i centri storici: da Smart Cities a Smart Heritage
2013
What is the relationship between contemporary cities of virtual networks and stakeholders with the historical centers, places of cultural and social heritage? The transformation of global cities make you thing on the contemporary relationship between man and historic center. The European proposal of the Smart Cities responds to the human need of identification in the living spaces, focusing on the six smart parameters involving people in making cities. The article lays the foundation to recognize the historic city as factor of urban regeneration starting from the analysis of some Smart historic centers in Italy and of the world most successful. The aim is to propose new smart models for the…
Multivariate optimization of the hollow fibre liquid phasemicroextraction of muscimol in human urine samples
2016
A liquid phase microextraction based on hollow fibre followed by liquid chromatographic determinationwas developed for the extraction and quantitation of the hallucinogenic muscimol from urine samples.Method applicability on polar hallucinogens was also tested on two alkaloids, a psychedelic hallucinogen,tryptamine and a polar amino acid, tryptophan which exists in its charged state in the entire pH range. Amultivariate design of experiments was used in which a half fractional factorial approach was applied toscreen six factors (donor phase pH, acceptor phase HCl concentration, carrier composition, stirring rate,extraction time and salt content) for their extent of vitality in carrier media…
