Balancing Flexibility and Coherence: Information Exchange in a Paper Machinery Project

1999

The problem of balancing coherence and flexibility in collaborative information system design is approached here with two pairs of concepts. Boundary objects can support communication for perspective taking between communities of practice. Conscripting devices can support communication for perspective making within a community of practice. These theoretical lenses are used to study the uses of the technical specification in paper machine projects. Our study showed that as a boundary object it provided enough flexibility to allow negotiations, and sufficient local structure, for carrying out work in both communities of practice, the customer and the manufacturer. As a conscription device in …

Hardware-efficient matrix inversion algorithm for complex adaptive systems

2012

This work shows an FPGA implementation for the matrix inversion algebra operation. Usually, large matrix dimension is required for real-time signal processing applications, especially in case of complex adaptive systems. A hardware efficient matrix inversion procedure is described using QR decomposition of the original matrix and modified Gram-Schmidt method. This works attempts a direct VHDL description using few predefined packages and fixed point arithmetic for better optimization. New proposals for intermediate calculations are described, leading to efficient logic occupation together with better performance and accuracy in the vector space algebra. Results show that, for a relatively s…

On Human–Computer Interaction in Brain–Computer Interfaces

2014

In this chapter, theoretical reflections on human–computer interaction in brain–computer interfaces (BCIs) are combined with the results of an empirical investigation concerning non-invasive EEG-based BCI users’ experiences with this technology. After a short overview of transhumanist visions in the field of neurotechnology this text discusses some anthropological positions concerning interaction between man and technical devices. The focus will be on the concept of “transparency”. Then some empirical results of a pilot study which investigated BCI users’ experiences concerning human–computer interaction in BCI use are presented and discussed against the anthropological background.

Tissue Sparing Posterior Cervical Indirect Decompression and Fusion in Foraminal Stenosis

2016

Treatment for patients with cervical foraminal stenosis that present with cervical radiculopathy has experienced rapid progress. Cervical spine surgical options have improved through advances in imaging, instrumentation, implant innovations and novel surgical techniques. While historical treatments are largely safe, comorbidities associated with procedures such as ACDF, TDR, and posterior foraminotomy beg the question if these procedures are too much surgery for select patients that could benefit from a tissue sparing approach. This chapter will introduce a novel, less disruptive surgical technique for achieving indirect decompression and fusion utilizing an intervertebral cervical implant.…

Human Surfaces

2020

Human Surfaces è un diario visivo interpretativo che mette in luce, in modo originale, un’iconografia di varie e potenziali diversità individuali (l’alter ego, l’attore, il visionario) protagoniste di scene immaginarie ma non per questo meno obiettive. Di Donato si muove in un territorio non solo di osservazione ma di costruzione dell’immagine, a sancire che la fotografia, come tutte le forme visuali autoriali, è un’emanazione che contiene il suo arte fice. Tessendo le fila delle sue visioni l’autore crea intersezioni, riconoscimenti, trasforma zioni, vere e proprie descrizioni dense di ciò che immagina e ritrae, svelando le relazioni di senso affidate alle immagini e all’immaginario. Le su…

Foucault, pastoral power, and optics

2015

The article shows that in Foucault’s late 1970s and early 1980s analyses of pastoral, conductive power—most essentially in early and medieval Christianity—the issue of sight and visual perception recurs and occupies a crucial status. In Foucault’s discussion, these Christian relations of power, knowledge, and truth are attached with a surveying gaze that is both totalizing as well as individualizing, one that is mobilized by the thrust towards perfect visibility, transparency, and illumination of the subject turned into an object. The intention is also to develop Foucault’s analysis further, by demonstrating how Christian, providential government can be and actually has been detached from …

Il paesaggio della Grecia nei Taccuini

2016

D’Annunzio does not dream, but really sees, leading an impressionistic and syncopated storytelling in which he portrays scenes of true reality. Léon Bakst (author of the theatrical productions of the Martyre de Saint Sébastien, La Pisanelle and Phaedra) similarly proceeds, drawing in some works, Narcisse (1911), L'Après-midi d'un Faune (1912), Daphnis et Chloé (1912), Helene de Sparte (1912), those figurative motifs that the poet notes in his travels, such as the intense green of nature, the austere red rocks, the arid and wild lands.
