The Time is Out of Joint ovvero come è stata riallestita la Galleria Nazionale nel tempo del senza tempo.
No full textNella complessa trama del tempo presente s’inscrive il lavoro di riallestimento della collezione della
Galleria Nazionale d’Arte Moderna e Contemporanea di Roma operato dalla direttrice Cristiana Collu.
The time is out of joint - questo lo shakespeariano titolo del progetto - è l’abbandono definitivo di
qualsiasi linearità storica, per una rilettura delle collezioni che dispiega su un piano cronologico
orizzontale le opere come sedimenti della lunga vita del museo. Il saggio riflette sui nodi centrali di
quest’itinerario, segnalando le tappe che l’hanno scandito – come l’esposizione temporanea The
Lasting. L’intervallo e la durata prologo alla riscrittura della collezione -, evidenziando la discontinuità
con i precedenti allestimenti della galleria e leggendo l’operazione nella traiettoria di trasformazione che
investe le pratiche espositive dei musei
Development of an electrical current stimulator for activating muscle tissues in biohybrid machines
No full textSoft and flexible robots are being developed as an alternative to traditional robotics. While they offer significant adaptability to the external environment, the integration of biological tissues as actuators presents several challenges. One of the critical challenges is the activation of the biological tissues to contract and move the robotic system's joints. In this paper, we discuss the development of an electrical current stimulator that can activate muscle tissues in soft robotic systems. The stimulator, realized with commercial components and designed using a stacked approach, combines a power supply board and an electrical stimulation front-end. A stacked-design approach allows to keep the device compact, with a total size of 59 mm x 28 mm x 25 mm (lxwxh). The stimulator, which has a power consumption of 1.3 W, can deliver up to 18 mA of stimulation current, and it has been verified to activate muscle tissues, demonstrating the ability to trigger muscle contraction by inducing up to 178 μN of contraction force
EFFECT OF THE BEAM FORMING NETWORK ON THE BEHAVIOR OF BROADBAND PLANAR WAVEGUIDE SLOT ARRAYS

No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
