Re-Inscription of Female Images and Subjectivities in Margaret Atwood’s The Robber Bride
2012
In exploring the complex female identity models that are articulated in Margaret Atwood’s The Robber Bride, this essay foregrounds Atwood’s sensitiveness to one of the major feminist issues of the early nineties: the debate over whether it is/was possible to postulate a distinctive “female specialness”. The essay's specific contention is that, in outlining the complex experiences of three Canadian friends – Tony, Roz and Charis – and of their demonic antagonist, Zenia, across three decades (from the sixties to the early nineties), Atwood questions notions of biological reductionism and, more importantly, the feminist creed of universal sisterhood4.
Le metamorfosi del corale "Vom Himmel hoch da komm ich her" fra Lutero, Bach e Stravinsky
2020
Il corale matalizio "Vom Himmel hoch da komm ich her" (Dall'alto dei cieli io giungo) è stato realizzato da Martin Lutero sulla base della melodia popolare "Ich komm aus fremden Landen her" e fu pubblicato per la prima volta a Wittenberg nel 1535. Assai diffuso in tutta l'area culturale tedesca, questo brano è stato ripreso, tra gli altri, anche da J.S. Bach, sia nel "Weinachts-Oratorium" BWV 248 che nelle "Canonische Veraenderungen" per organo BWV 796 e 796a. Il saggio ricostruisce il contesto in cui vide la luce la versione originale del canto natalizio e si sofferma sull'interesse di Bach per la numerologia e sulle "citazioni nascoste" in molte sue opere, incluse le "Veraenderungen" sul …
Robot passes the mirror test by inner speech
2021
Abstract The mirror test is a well-known task in Robotics. The existing strategies are based on kinesthetic-visual matching techniques and manipulate perceptual and motion data. The proposed work attempts to demonstrate that it is possible to implement a robust robotic self-recognition method by the inner speech, i.e. the self-dialogue that enables reasoning on symbolic information. The robot self-talks and conceptually reasons on the symbolic forms of signals, and infers if the robot it sees in the mirror is itself or not. The idea is supported by the existing literature in psychology, where the importance of inner speech in self-reflection and self-concept emergence for solving the mirror…

Lessons Learned on the Tensile and Bond Behavior of Fabric Reinforced Cementitious Matrix (FRCM) Composites
2020
Fabric Reinforced Cementitious Matrix (FRCM) composites represent an effective, compatible and cost-efficient solution for strengthening and retrofitting existing structures. A strong research effort was done to investigate the tensile and bond properties of these materials, as well as the overall behaviour of strengthened members. A Round Robin Test was organized by Rilem TC 250-CSM on 28 FRCM composites comprising basalt, carbon, glass, PBO, aramid and steel textiles, embedded in either cement, lime or geopolymer mortars, to collect an experimental dataset and define test protocols. This paper collects the outcomes of this study to highlight fundamental properties of FRCM and to investiga…
Switchable surface structured hydrogel coatings
2017
Switchable surface structures based on hydrogels are an emerging field in material science, microfluidics, soft robotics and anti-fouling. Here, we describe a novel method that uses a photo-cross-linkable terpolymer to create a hydrogel coating with a switchable surface structure. The terpolymer is based on poly(N-isopropylacrylamide) (PNIPAm) and it is shown that simple coating technologies like slit die coating can be used under ambient conditions. It is also shown that the swelling ratio of the coating is controlled by the energy dose of ultraviolet (UV) light. Simple and complex surface structures were created using respectively single or multiple UV illumination steps through masks and…
Wavelength-Gated Adaptation of Hydrogel Properties via Photo-Dynamic Multivalency in Associative Star Polymers.
2020
Abstract Responsive materials, such as switchable hydrogels, have been largely engineered for maximum changes between two states. In contrast, adaptive systems target distinct functional plateaus between these maxima. Here, we demonstrate how the photostationary state (PSS) of an E/Z‐arylazopyrazole photoswitch can be tuned by the incident wavelength across a wide color spectrum, and how this behavior can be exploited to engineer the photo‐dynamic mechanical properties of hydrogels based on multivalent photoswitchable interactions. We show that these hydrogels adapt to the wavelength‐dependent PSS and the number of arylazopyrazole units by programmable relationships. Hence, our material des…
A Simple Indicator Based Evolutionary Algorithm for Set-Based Minmax Robustness
2018
For multiobjective optimization problems with uncertain parameters in the objective functions, different variants of minmax robustness concepts have been defined in the literature. The idea of minmax robustness is to optimize in the worst case such that the solutions have the best objective function values even when the worst case happens. However, the computation of the minmax robust Pareto optimal solutions remains challenging. This paper proposes a simple indicator based evolutionary algorithm for robustness (SIBEA-R) to address this challenge by computing a set of non-dominated set-based minmax robust solutions. In SIBEA-R, we consider the set of objective function values in the worst c…
The facility layout problem approached using a fuzzy model and a genetic search
2005
The problem of facility layout design is discussed, taking into account the uncertainty of production scenarios and the finite production capacity of the departments. The uncertain production demand is modelled by a fuzzy number, and constrained arithmetic operators are used in order to calculate the fuzzy material handling costs. By using a ranking criterion, the layout that represents the minimum fuzzy cost is selected. A flexible bay structure is adopted as a physical model of the system while an effective genetic algorithm is implemented to search for a near optimal solution in a fuzzy contest. Constraints on the aspect ratio of the departments are taken into account using a penalty fun…
