Designing the Hybrid and the Fragmentary. Four participatory planning projects at the fringe of Italian cities
No full textFringe areas and their restrictions are different from the inner city. Often they require an entirely new approach toward urban planning. Our author reports on four different planning projects in Italy. What connects them is their location at the fringe of metropolitan cities, the relevance of indeterminacy, the attention to the continuity of ecological and public networks and the attempt to build new scenarios with the materials found at the project site, following very short supply chains
PAMELA recent results on galactic proton and helium
No full textPAMELA is a satellite borne experiment designed to study with great accuracy cosmic rays of galactic, solar, and trapped nature in a wide energy range (protons: 80 MeV–1200 GeV, electrons 50 MeV–600 GeV). Main objective is the study of the antimatter component: antiprotons (80 MeV–190 GeV), positrons (50 MeV–270 GeV) and search for antinuclei (with a precision of the order of 10−8). The experiment, housed on board the Russian Resurs-DK1 satellite, was launched on June, 15th 2006 in a 350 × 600 km orbit with an inclination of 70°. In this work we report on the recent results on proton and helium of galactic origin, their solar modulation and the helium isotopic component

Circular planning and adaptive design strategies to recycle wasted landscapes: The per-urban territories of campania plain as a case study
No full textThe Campania Region, in the South of Italy, is a territory where numerous Wasted Landscapes (WL) are recognisable, as the result of serious socialand governmental problems.Through the last decades, many factors have been overlapping in this complex palimpsest: illegal developments and the measures to legitimizethem can be paradoxically understood as real cornerstones for the local planning system; the traces of the post-Fordist abandoned landscapes aremixed with the historical remains, showing the deep sense of identity that still persists in the territory. On the other hand, the Campania Plainis a porous territory characterised by an adaptive resilience. This is interwoven with the presence of areas of outstanding natural beauty, with aresilient interstitial agriculture, and with a fragmented but resistant economy.In this paper, two emblematic case-studies are discussed (Casaluce and Est-Naples), understanding WL as an additional category of waste withthe urgent need to be recycled, in order to: reactivate urban metabolism; to improve the quality of life, the spatial quality of the territory, and theregional economy.Environmental Technology and Desig

Measurements of He isotopic ratio in cosmic rays in the 100 MeV - 1 GeV range with the PAMELA experiment
No full textThe PAMELA satellite-borne experiment was launched on 15 June 2006 from the Baikonur cosmodrome and it has been collecting data since then. The apparatus comprises a time-of-flight system, a silicon-microstrip magnetic spectrometer, a silicon-tungsten electromagnetic calorimeter, an anticoincidence system, a shower tail counter scintillator and a neutron detector. The combination of these devices allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (100 MeV - 1 TeV) with high statistics, with particular focus on the antiparticle component. In this work we present 3He/4He isotopic ratio in the energy range from 100 MeV nucleon-1 to ~1 GeV nucleon-1. The measured abundances are compared with different interstellar/heliospheric propagation calculations which are tuned on previous proton and helium measurements
Modulation of Galactic Protons in the Heliosphere During the Unusual Solar Minimum of 2006 to 2009
No full textThe last solar minimum activity period, and the consequent minimum modulation conditions for cosmic rays, was unusual. The highest levels of galactic protons were recorded at Earth in late 2009 in contrast to expectations. Proton spectra observed for 2006 to 2009 from the PAMELA cosmic ray detector on-board the Resurs-DK1 satellite are presented together with the solutions of a comprehensive numerical model for the solar modulation of cosmic rays. The model is used to determine what mechanisms were mainly responsible for the modulation of protons during this period, and why the observed spectrum for 2009 was the highest ever recorded. From mid-2006 until December 2009 we find that the spectra became significantly softer because increasingly more low energy protons had reached Earth. To simulate this effect, the rigidity dependence of the diffusion coefficients had to decrease significantly below ̃ 3 GeV. The modulation minimum period of 2009 can thus be described as relatively more `diffusion dominated' than previous solar minima. However, we illustrate that drifts still had played a significant role but that the observable modulation effects were not as well correlated with the waviness of the heliospheric current sheet as before. Protons still experienced global gradient and curvature drifts as the heliospheric magnetic field had decreased significantly until the end of 2009, in contrast to the moderate decreases observed during previous minimum periods. We conclude that all modulation processes contributed to the observed increases in the proton spectra for this period, exhibiting an intriguing interplay of these major mechanisms
A plugin-based approach to data analysis for the AMS experiment on the ISS
No full textIn many HEP experiments a typical data analysis workflow requires each user to read the experiment data in order to extract meaningful information and produce relevant plots for the considered analysis. Multiple users accessing the same data result in a redundant access to the data itself, which could be factorized effectively improving the CPU efficiency of the analysis jobs and relieving stress from the storage infrastructure. To address this issue we present a modular and lightweight solution where the users code is embedded in different "analysis plugins" which are then collected and loaded at runtime for execution, where the data is read only once and shared between all the different plugins. This solution was developed for one of the data analysis groups within the AMS collaboration but is easily extendable to all kinds of analyses and workloads that need I/O access on AMS data or custom data formats and can even adapted with little effort to another HEP experiment data. This framework could then be easily embedded into a "analysis train" and we will discuss a possible implementation and different ways to optimise CPU efficiency and execution time
