A Low-Power, Short Dead-Time ASIC for SiPMs Readout with 200 MS/s Sampling Rate

The design of a low-power, 64-channels front-end ASIC for Silicon Photomultipliers is presented. The chip is being developed in a 65 nm CMOS technology and it is optimised for space applications. In each channel, the current pulse delivered by the sensor is amplified, converted into a voltage and sampled at 200 MS/s by an array of 256 cells, each containing a storage capacitor and a single-slope ADC. If a trigger signal is received, the analog samples are digitised in parallel and sent off-chip, otherwise the memory cells are overwritten. The ADC resolution can be programmed in the 7-12 bit range, trading-off dead time with amplitude resolution. The target power consumption is 5 mW/channel. The chip can thus take snapshots of relatively rare events at high sampling rate with low power. The analog memory can be partitioned in shorter slots that work in a time-interleaved configuration. In this way, the input data stream, which usually follows a Poisson distribution, can be derandomized. The chip is scheduled to be submitted for fabrication in the second quarter of 2022. In the paper, the design concept is presented and the ongoing verifications are discussed

From textile waste to resource: a methodological approach of research and experimentation

The transition to a circular economy shifts the focus onto reusing, renewing and recycling existing materials and products, considering waste as a resource. In this context, the article aims to describe the life cycle approach's potential for the development of new building products from textile waste, one of the most environmentally impacting activities at global level, both in relation to the processes that characterise the supply chain and in relation to pre and post-consumption waste. The article outlines the research methodology adopted by the Cluster "From textile waste to resource" of the Department of Architecture and Design, Politecnico di Torino, through the description of research projects carried out in partnership with Small and Medium Enterprises (SMEs). In particular, it highlights the methodological approach adopted, in a "grave to cradle" logic, in which the waste from one process becomes a new resource for another. The article highlights some open issues related to limits and potential of the use of life cycle approach as a “tool” to compare different options in a preliminary experimental research phase, to verify the environmental impacts of new materials and products made from recycled materials, to compare new options with similar solutions available on the market

Building the fashion’s future. How turn textiles’ wastes into ecological building products

The textile system is one of the most influential production activities at a global level from an environmental point of view, both in relation to the processes that characterize the supply chain and in relation to pre and post-consumer waste. It produces million tons of global greenhouse gas emissions per year and it consumes millions of litres of water; it uses million tons of chemical products. Furthermore, millions of tones of special textile wastes are yearly landfilled in upstream process as well as in downstream process. Less of 1% of materials used to produce clothes becomes part of a closed-loop recycling and less of 2% are recycled in other industrial activities. Changing the textile industrial linear model in a circular one according to Systemic Design principles is advisable, starting from wastes and by-products. As proved in the working paper wastes, due to their properties, can assumed as inputs of new production systems. Particularly the scientific contribution deals with some research activities carried out within a project titled EDILTEX - Innovation for reusing in textile companies. The achievements are described, showing that construction and fashion are fields only apparently far from each other. They can - on the contrary - developing powerful synergies and products with interesting technological and physical performances

As práticas do dizer e os processos de subjetivação

Seguindo ponto de vista transdisciplinar na clínica, o trabalho analisa a aliança entre os estudos da subjetividade e algumas propostas de Foucault e de Deleuze. A proposta é redefinir a clínica a partir da crítica à concepção de subjetividade como substância, naturalizada por leis universais estritamente psíquicas, responsáveis por sua regularidade e contornos conceituais bem delimitados e imutáveis. A relação entre subjetividade e práticas discursivas é explorada como processo de produção recíproca, onde modos de dizer e modos de existir emergem dos jogos de forças. Duas modalidades de movimento das forças são sublinhadas, deixando ver os dois pólos do processo de subjetivação: produções subjetivas homogeneizantes e invenção de novos modos de funcionamento. A tarefa clínica, neste contexto, se cumpriria no zelo pelo duplo movimento, pelo qual a subjetividade preservaria seu caráter processual, distante de uma constituição substantiva. Palavras-chave: subjetividade; clínica; literatura.Assuming a transdisciplinary point of view in the clinical work, this paper investigates the alliance bet ween the studies of subjectivity and the thought of Foucault and Deleuze. Our purpose is to redefine clinical practice in accordance with their critique of the conception of subjectivity as a substance, naturalized by strictly psychological universal laws, responsible for their regularity and well established and unchangeable conceptual contours. The relationship between subjectivity and discursive practices is explored as a process of mutual production, in which speech modalities and modalities of existence emerge from the interplay of forces. Two modalities of the forces in movement are emphasized, so that the two poles of the process of subjectivation can be seen: subjective productions that lead to homogenization and the invention of new modes of existence. In such context, the clinical task would be carried out by carefully maintaining the double movement, by which subjectivity could preserve its processing nature as opposed to a substantial constitution.

How to measure the green façade sustainability? A proposal of a technical standard.

Different guidelines drive EU countries to use greening systems – green roofs and green façades - as a sustainable strategy to maximize environmental buildings performance. While technical standards concerning green roofs are available, standards concerning green façades and particularly Living Wall Systems (LWSs) still missing. The paper deals with a research carried out in order to develop a proposal of a technical standard to be adopted as method and tool to measure the performances of green façades and LWSs according to a sustainable approach. The proposal was implemented in consistency to an Italian standard (UNI 11235:2015). The UNI 11235 contains the instructions for designing, building up, monitoring and maintaining the green roofs. Although the standard is not international some basic information may be applied at global scale and most importantly at green façades. The study was focused to setting-up a proper number of requirements to be met in: designing a LWS; defining guidelines for construction stage; monitoring the performance. Requirements and guidelines were set up according to a wide study on international references and thanks to an industrial research project where the authors were involved. Monitoring carried out on chamber tests and on-site was enabled to getting comprehensive data helpful for assessing environmental properties of LWSs and on the whole to characterizing some requirements to be used in the standard

Designing Circularity. The circular economy for landscape and territory

A farm, a biomedical company and a building materials company, an area with a high landscape val- ue, some agricultural and food waste to be optimised, a team of researchers and a class of design and architecture students. These are the ingredients of the Designing Circularity experience. The article illustrates a field research activity and an educational experiment focused on identifying circularity scenarios for the territory and the development of a project based on the principles of the circular economy, with an appropriate technology approach. The result is that grape marc becomes bricks and hazelnut shells become insulating panels. The experience generated results for all the players in- volved: the companies strengthened their industrial symbiosis strategies; the university took respon- sibility for co-processing circularity scenarios and territorial development; the students developed a critical sense and the ability to design in close contact with real ‘challenges’
