Lone Star Stack: Architecture of a Disk-Based Archival System
2014
The need for huge storage systems rises with the ever growing creation of data. With growing capacities and shrinking prices, "write once read sometimes" workloads become more common. New data is constantly added, rarely updated or deleted, and every stored byte might be read at any time - a common pattern for digital archives or big data scenarios. We present the Lone Star Stack, a disk based archival storage system building block that is optimized for high reliability and energy efficiency. It provides a POSIX file system interface that uses flash based storage for write-offloading and metadata and the disk-based Lone Star RAID for user data storage. The RAID attempts to spin down disks a…
Social mirrors. Tove Jansson’sInvisibleChildand the importance of being seen
2016
ABSTRACTThis article examines the experience of being seen and analyzes its central role in the formation of a coherent sense of self. Tove Jansson’s short story from 1962, ‘The Invisible Child’, serves as the red thread of the article, and the story is analyzed in the light of Donald Winnicott’s work on social mirroring. The analysis is enriched by the psychoanalytic insights of Veikko Tahka and Heinz Kohut, and complemented by Axel Honneth’s philosophical elaborations as well as by recent developmental findings as presented by Vasudevi Reddy. The article is divided into an introduction and three sections. After summarizing Jansson’s story in the introduction, the first section elaborates …
A spiking network for spatial memory formation: Towards a fly-inspired ellipsoid body model
2013
Neural centers devoted to spatial memory and path integration were largely studied in rats and in different insect species like ants and bees. In this paper a neural-based model for the formation of a spatial working memory is proposed mirroring some peculiarities of the Drosophila central brain and in particular the ellipsoid body. Simulation results are reported opening the way to applications on roving platforms.
Joan Roís de Corella, La Istòria de Leànder y Hero: edizione critica con studio introduttivo
2018
This contribution is a further partial anticipation of the critical edition of the mythological faules of Joan Roís de Corella (15th century) for Barcino (ENC), after that appeared in Magnificat, vol.3, 2016. It focuses on one of the author's most mature and significant faules, as well as one of the most prestigious testimonies both of the presence of the myth of Ero and Leandro in the Iberian 15th century, and of the peninsular reception of the Heroides. The paper consists of two parts. In the first part, Introduction, the current situation of the studies related to the Istòria is first summarized. Next, the analysis of the literary memory that supports the discursive construction of the f…
Is that me in the mirror? Depersonalisation modulates tactile mirroring mechanisms
2016
Our sense of self is thought to develop through sensory-motor contingencies provided, not only by observing one's own body, but also by mirroring interactions with others. This suggests that there is a strong link between mirroring mechanisms and the bodily self. The present study tested whether this link is expressed at early, implicit stages of the mirroring process or at later, more cognitive stages. We also provide, to the best of our knowledge, the first demonstration of how inter-individual differences in our sense of bodily self may affect mirroring mechanisms. We used somatosensory event-related potentials (SEPs) to investigate the temporal dynamics of mirroring highly self-related …
LoneStar RAID
2016
The need for huge storage archives rises with the ever growing creation of data. With today’s big data and data analytics applications, some of these huge archives become active in the sense that all stored data can be accessed at any time. Running and evolving these archives is a constant tradeoff between performance, capacity, and price. We present the LoneStar RAID, a disk-based storage architecture, which focuses on high reliability, low energy consumption, and cheap reads. It is designed for MAID systems with up to hundreds of disk drives per server and is optimized for “write once, read sometimes” workloads. We use dedicated data and parity disks, and export the data disks as individu…
The analysis of urban travellers’ latent preferences to explain their mode choice behaviour
2012
Our research aims to explore the impact of latent variables, mirroring urban travellers’ attitudes and perceptions, on the individual decision making process regarding the mode of transport. The paper describes the first results of an ongoing research activity, which derive from a pilot study conducted in Palermo, the capital of the Sicilian Region (in the south of Italy), and demonstrate that policy makers, in designing a socially desirable and environmentally sustainable urban mobility system, should take into account how travellers perceive the qualitative dimensions of transport.
