An adequate explication of miscomputation should do justice to relevant practices in the computational sciences. While philosophers of computation have neglected scientific practices outside computer science, here I focus on computational psychiatry. I argue that computational psychiatrists use a concept of miscomputation in their explanations, and that this concept should be explicated as interest-relative and perspectival, although non-arbitrary, relatively clear-cut, experimentally evaluable, and instrumentally useful. To the extent my argument is convincing, we should reconsider the general adequacy of the mechanistic view of computation for illuminating relevant methodological and explanatory practices in the computational sciences.

This paper reports the design and the realization of the energetic renovation of a residential building owned by ALER and located in Cinisello Balsamo (MI), by mean of the installation on the existing facades of an innovative insulating prefabricated sandwich panel, for a total of about 520 m2 covered. The energetic renovation process has been organized in the following steps: survey campaign of the existing building’s envelope by means of laser scanning technologies and thermographic survey for the identification of non-homogeneous parts of the building structure, to support the technological design as well as the installation of the prefabricated panels; use of Building Information Modeling (BIM) aimed at supporting the design of both the prefabricated panels and the anchoring systems, towards the automation in the installation of the elements as well as the energy performance evaluation over time; architectural and executive design of the energetic renovation and manufacturing of 186 insulating prefabricated panels, for a total of 28 different typologies, having different sizes, colors and finishing (with and without specific textures); panels’ installation to the existing building facades by means of steel profiles and realization of the finishing works.

Fibre reinforced concrete is a concrete with a diffused reinforcement based on fibre pull-out resistance and its toughness in tension is strongly affected by fibre distribution. The material response of a representative volume is significantly affected by the uncertainties related to fibre location and number: only a homogeneous distribution of fibres can guarantee an isotropic behaviour, but in any case its mechanical behaviour dominated by mode I failure, identified by means of a bent notched beam, shows a large standard deviation. By the way, a structure characterized by a significant capability to redistribute stresses and large fracture volume at the onset of collapse can reduce the sensitivity to the high standard deviation and exhibits a bearing capacity aligned to the average mechanical properties of the composite. In the paper several approaches to compute the coefficient that quantifies this structure ability, K Rd , are proposed, taking as a reference cases a slab on ground and an elevated slab.

Fabric-Reinforced Cementitious Matrix (FRCM) composites are an effective mean to retrofit damaged structures. Their action depends not only on the behavior in tension of the introduced materials, but also on the bond of the composite with the original substrate. A new Italian standard will be soon introduced, thought to allow the designer to compute the effectiveness of cement-based Externally Bonded Reinforcements (EBR) by combining simple uniaxial tensile tests with shear bond tests. An experimental investigation of FRCMs made of an Alkali-Resistant (AR) glass fabric combined with different matrices and dispersed Polyvinyl Alcohol (PVA) or high-carbon steel microfibers is presented. In this regard, relevant design parameters are matrix toughness and mortar thixotropy. Following the characterization at the material and at the interface scales, the design procedures introduced by the standard are discussed and critically evaluated with reference to an alternative basic test based on Double Edge Wedge Splitting (DEWS) principles. Preliminary conclusions concerning the reliability of the proposed approach are finally drawn.
