Common Spaces in Nomadic Housing: Two Types of Intended Use in Turin City Centre
No full textNew nomadism is a movement of global intensification that configures ways of living, inhabiting, and being in the world. The case studies of the temporary residences in Turin, in areas characterized by problems of urban decay and social tensions with a high rate of immigration, are both a technical and social experimental intervention aiming, through the recovery of the existing degraded property, to transform it into a new living model of social housing, from which it will benefit not only the residents but also the entire urban area. The concept of the spaces has profoundly changed. It is no longer tied to the domestic and work sphere only, it now includes all places of associated and collective life
Correlating creep properties of bituminous binders with anti-rutting performance of corresponding mixtures
No full textIn the experimental study described in this paper, rutting properties of different bituminous binders and those of corresponding mixtures characterized by common composition and volumetrics were investigated and compared. Single shear creep-recovery (SSCR) tests were carried out on binders for the determination of their creep compliance rate (CCR), whereas bituminous mixtures were evaluated by referring to their Flow Number (FN), derived from repeated compressive loading tests. Analysis of experimental data revealed the existence of a strong correlation between rutting parameter of binders and permanent deformation response of mixtures. This confirmed the potential of the proposed testing procedure of being adopted for the evaluation of rutting properties of bituminous binders and for their consequent perfomance-related ranking

Photoanode/Electrolyte Interface Stability in Aqueous Dye-Sensitized Solar Cells
No full textO'Regan and Grätzel conceived a dye-sensitized solar cell (DSSC), which operates as an artificial photosynthetic system converting solar light into electricity. Nevertheless, it is only recently that the scientific community is focusing on truly aqueous DSSCs that use water as electrolyte, thus avoiding any flammable and toxic organic solvents. The most critical aspect of these devices is the photoanode/electrolyte interface. Indeed, it is necessary to select dyes that chemisorb onto the semiconductor layer while allowing the aqueous electrolyte to thoroughly impregnate the mesostructure of the electrode; at the same time, it is necessary to avoid the anchoring unit of the dye to be hydrolyzed by water, thus causing the detachment of the sensitizer from the active material particles. This requires a thorough analysis of the structure-property relationships, in particular the evaluation of the chemical formula, stability, and performances of the dyes on the electrode surface in truly aqueous environment. Herein, we investigate nine different sensitizers, selected based on their different properties in terms of light absorption, chemical structure, and hydrophobic/hydrophilic nature. Wettability, resistance to dye desorption, and spectral variations of sensitized photoanodes, along with the photovoltaic performance of the resulting devices, are systematically investigated to identify some useful guidelines to choose and design suitable dyes of different colors for truly aqueous DSSCs
Social housing evaluation procedures: literature review and steps forward
No full textThe purpose of this research is to contribute to the lack of evaluation procedures (identified in the academic literature) able to tackle the complexity of Social Housing (SH) sector. We analysed the evaluation procedures currently suggested in the literature on SH, in order to understand what methodologies are proposed/applied and we checked if the evaluation procedures identified are able to tackle the current trends occurring in the SH provision in Europe. Operatively, we apply a review framework structured into keywords derived from the official SH definitions provided by CECODHAS Housing Europe. First, the keywords are linked to the bibliographic references of scientific journals and to the country of each study analysed over the past fifteen years, from 2000 to 2015. Second, the papers identified are reviewed by checking whether or not they present evaluation procedures. Third, a geographical distribution of the papers is provided. The results of this review show that, even if several evaluation procedures are clearly identified and applied in SH, none of the papers analysed deals with all the SH keywords in an integrated perspective. To contribute filling this gap, we finally propose a conceptual decision framework based on the integration between Multicriteria Decision Analyses (MCDA) and Information and Communication Technologies (ICT), able to balance the different SH issues seen not as trade off but complementary. This shift is not intended simply as a shift in the method/tool used to acquire information but also as an improvement in the quality and quantity of the information themselves
TMsim: An Algorithmic Tool for the Parametric and Worst-Case Simulation of Systems with Uncertainties
No full textThis paper presents a general purpose, algebraic tool—named TMsim—for the combined parametric and worst-case analysis of systems with bounded uncertain parameters.The tool is based on the theory of Taylor models and represents uncertain variables on a bounded domain in terms of a Taylor polynomial plus an interval remainder accounting for truncation and round-off errors.This representation is propagated from inputs to outputs by means of a suitable redefinition of the involved calculations, in both scalar and matrix form. The polynomial provides a parametric approximation of the variable, while the remainder gives a conservative bound of the associated error. The combination between the bound of the polynomial and the interval remainder provides an estimation of the overall (worst-case) bound of the variable. After a preliminary theoretical background, the tool (freely available online) is introduced step by step along with the necessary theoretical notions. As a validation, it is applied to illustrative examples as well as to real-life problems of relevance in electrical engineering applications, specifically a quarter-car model and a continuous time linear equalizer
Academy transaction note characterization of FRAM microcontrollers to radiations
No full textThis work is focused on the development of a payload tile for the AraMIS structure called 1B521 Radiation characterization Payload to test new FRAM microcontrollers. These components are very appealing for space applications because of low power consumption compared with standard FLASH based ones
Design and Development of One-Switch Video Games for Children with Severe Motor Disabilities
No full textVideo games are not just played for fun; they have become a handy instrument for the cognitive, emotional, and social development of children. However, several barriers prevent many children with disabilities from playing action-oriented video games, alone or with their peers. In particular, children with severe motor disabilities, who rely on one-switch interaction for accessing electronic devices, find fast-paced games that require rapid decision-making and timely responses, completely unplayable. This article contributes to lowering such barriers by presenting GNomon (Gaming NOMON), a software framework based on the NOMON mode of interaction that allows the creation of action-oriented single-switch video games. The article reports the results of two studies that evaluate the playability and rehabilitation suitability of GNomon-based video games. The playability of GNomon-based games is evaluated by assessing their learnability, effectiveness, errors, satisfaction, memorability, and enjoyability with a group of eight children with severe motor disabilities. The suitability for pediatric rehabilitation is determined by means of a focus group with a team of speech therapists, physiotherapists, and psychologists from a Local Health Agency in Turin, Italy. The results of the playability study are positive: All children had fun playing GNomon-based video games, and seven of eight were able to interact and play autonomously. The results of the rehabilitation-suitability study also entail that GNomon-based games can be exploited in training hand-eye coordination and maintenance of selective attention over time. The article finally offers critical hindsight and reflections and shows possible new future game concepts
