Using human-values as a guide for understanding worthy design directions in augmented reality

2016

Augmented reality is a fast developing field, which will no doubt gain strong footing in the area of social media in the near future. Recently, Google Glass placed AR towards the top of the technological hype curve in regards to interaction possibilities, information overlay, information search and recording. Questions still remain however, regarding the added-value that AR offers to already existing interaction modes and technologies. In this study four concepts were designed and tested via video scenarios. The concepts related to three main product categories: educational tools; information presentation; and x-ray vision. The results positively reflected on the application of AR for educa…

Uncertainty and sensitivity analysis for reducing greenhouse gas emissions from wastewater treatment plants.

2020

Abstract This paper presents the sensitivity and uncertainty analysis of a plant-wide mathematical model for wastewater treatment plants (WWTPs). The mathematical model assesses direct and indirect (due to the energy consumption) greenhouse gases (GHG) emissions from a WWTP employing a whole-plant approach. The model includes: i) the kinetic/mass-balance based model regarding nitrogen; ii) two-step nitrification process; iii) N2O formation both during nitrification and denitrification (as dissolved and off-gas concentration). Important model factors have been selected by using the Extended-Fourier Amplitude Sensitivity Testing (FAST) global sensitivity analysis method. A scenario analysis h…

Disposal of green roofs: A contribution to identifying an “Allowed by legislation” end–of–life scenario and facilitating their environmental analysis

2022

The rapid and widespread deployment of green roofs requires the need to address their disposal and to assess the environmental impact of this phase of their life cycle to understand whether their current large-scale application may pose a problem. A review of the literature on green roofs environmental performance (particularly Life Cycle Assessment studies) has highlighted the lack of a standardized, commonly adopted, procedure for determining the treatments, recovery and/or disposal, to be assigned to waste from the removal of green roofs. In this regard, it should be mentioned that there is a lack of ad hoc legislation on the disposal of this technology (to the best of the authors’ knowl…

Exploring relationships between drought and epidemic cholera in Africa using generalised linear models

2021

Abstract Background Temperature and precipitation are known to affect Vibrio cholerae outbreaks. Despite this, the impact of drought on outbreaks has been largely understudied. Africa is both drought and cholera prone and more research is needed in Africa to understand cholera dynamics in relation to drought. Methods Here, we analyse a range of environmental and socioeconomic covariates and fit generalised linear models to publicly available national data, to test for associations with several indices of drought and make cholera outbreak projections to 2070 under three scenarios of global change, reflecting varying trajectories of CO2 emissions, socio-economic development, and population gr…

Convivere con le emergenze. Design e nuovi scenari domestici

2023

The contribution leads a reflection around the physical-relational processes that have always characterized the domestic interior and that the recent state of health emergency Covid-19 (and the even more recent Russian-Ukrainian war conflict) has catalysed and accentuated, if not exasperated, offering new complex and sometimes contradictory visions. The contribution points to focus on new meanings and new projections, in terms of interactions and relationships, assumed by the consolidated physical-cultural criteria of proximity/remoteness, familiarity/foreignness, inside/outside. Within these profound transformations, an opportunity and a new role are looming for the disciplines of design. …

Hard Cap Espresso Machines in Analytical Chemistry: What Else?

2016

A hard cap espresso machine has been used in combination with liquid chromatography with molecular fluorescence detection for the determination of polycyclic aromatic hydrocarbons (PAHs) from contaminated soils and sediments providing appropriate extraction efficiencies and quantitative results. Naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benz[a]anthracene, chrysene, benz[b]fluoranthene, benz[k]fluoranthene, benz[a]pyrene, dibenz[a,h]anthracene, benz[ghi]perylene, and indeno[1,2,3-cd]pyrene were used as target compounds. It should be mentioned that the pairs benz[a]anthracene-chrysene and dibenz[a,h]anthracene-benz[ghi]perylene peaks coelute under th…

Sensitive determination of polycyclic aromatic hydrocarbons in water samples using monolithic capillary solid-phase extraction and on-line thermal de…

2011

A methacrylate-based monolithic capillary column has been evaluated for the preconcentration of polycyclic aromatic hydrocarbons (PAHs) from environmental water samples. For this purpose, the monolyte was in situ synthesized in a 6cm×0.32mm id fused-silica capillary. The microextraction unit was fitted to a micro-HPLC pump to pass 10mL of sample. The isolated pollutants were eluted by means of 10μL of methanol, the organic phase being directly collected in a specific interface that can be fitted to the injection port of the gas chromatograph without modification. The interface allows the on-line thermal desorption of the PAHs, avoiding the dilution and providing enough sensitivity to reach …

FUTURE IS BACK

2017

«Trent'anni fa, un piano per il futuro di New York sarebbe apparso futile» Michael R. Bloomberg, sindaco di New York, che ha introdotto nel 2007 la relazione sul futuro della città per il 2030, PlaNYC, oppose la città degli anni 1970, «interamente concentrata sulla risoluzione di crisi immediate», alla città di quegli anni, «più forte che mai»: consapevole di aver ritrovato il desiderio del futuro. La data dell'11 settembre non è percepita come un presagio della fine della supremazia americana, è un evento superato - Future is back ! Questo ritorno nel futuro è immaginato da tutte le metropoli preoccupate di inserirsi nel mercato dell'attrattività3. Trent'anni dopo la fine del progresso, l'…
