Il contenimento del consumo di suolo a scala europea: il Programma ESPON

La pianificazione e lo sviluppo territoriale hanno informato l’agenda europea negli ultimi 10 anni soprattutto attraverso l’European Spatial Planning and Development Perspective (ESDP) formalizzatosi attraverso gli studi dell’European Spatial Planning Observatory Network (ESPON) e le Guidelines for the Sustainable Development of the European Continent del Council of Ministers of the Wider Europe with responsibility for Regional Planning (CEMAT)). Pur inizialmente lontani da quella concezione pienamente territoriale propria del pensiero geografico ed urbanistico italiano, che si è manifestata solo nel 2007, questi contributi rappresentano un forte incentivo a rinnovare l’atteggiamento politico, economico, culturale nei confronti del valore che il territorio, la sua utilizzazione e la sua identità hanno per lo sviluppo. Di fronte a queste sollecitazioni, nell’ultimo quinquennio il Programma ESPON si è aperto alla revisione dei paradigmi e dei contenuti operativi disciplinari, affrontando e sviluppando temi quali: i cambiamenti strutturali e le grandi tendenze del territorio europeo tra il 1998 e il 2007 (la coesione, sostenibilità e il cambiamento climatico, il policentrismo, l’urbano-rurale, la dimensione competitiva delle città anche medio-piccole, la governance, il cambiamento demografico, ecc.); l’integrazione tra i principi della ricerca geoeconomica e della pianificazione attraverso la creazione di modelli multidisciplinari applicabili a differenti scale - NUTs 2, 3, 4 - per l’individuazione delle capacità competitive endogene entro i limiti di sostenibilità; le procedure e gli strumenti di valutazione comuni per la scelta di politiche e piani/programmi in applicazione delle direttive europee (Territorial Impact Assessment – TIA); lo sviluppo di GIS e database dedicati alla conoscenza e alla gestione di processi cooperativi comparabili trasparenti, sussidiari, integrati; la definizione e l’applicazione di un protocollo di indicatori statistico-economico-geografici condivisi e certificati a sostegno dei processi decisionali; lo sviluppo di case study transnazionali sui temi principali della politica UE. In Italia, molti di questi cambiamenti sono stati introdotti e sperimentati attraverso i progetti speciali, tematici, strategici ESPON, confermando il valore di nuovi orientamenti geografici e della pianificazione, che coinvolgono direttamente i policy makers. I risultati dei progetti di ricerca transnazionale ESPON promossi tra il 2000-2006 e il 2007-2010 , ed in particolare quelli più legati alla dimensione territoriale ed urbana delle strategie europee in applicazione della Territorial Agenda 2007, hanno consentito di misurare e sperimentare anche in Italia indicatori, metodi, criteri di ricerca comuni, rivelatisi utili alla discussione internazionale e nazionale che accompagnano la revisione di molti temi, tra cui l’uso del suolo, la città e il suo rapporto con con l’area vasta di più stretta pertinenza, la provincia come luogo centrale della sussidiarietà europea (Prezioso, 2009)

Performance of the CMS Cathode Strip Chambers with Cosmic Rays

The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns

Commissioning of the CMS high-level trigger with cosmic rays

This is the Pre-print version of the Article. The official published version of the paper can be accessed from the link below - Copyright @ 2010 IOPThe CMS High-Level Trigger (HLT) is responsible for ensuring that data samples with potentially interesting events are recorded with high efficiency and good quality. This paper gives an overview of the HLT and focuses on its commissioning using cosmic rays. The selection of triggers that were deployed is presented and the online grouping of triggered events into streams and primary datasets is discussed. Tools for online and offline data quality monitoring for the HLT are described, and the operational performance of the muon HLT algorithms is reviewed. The average time taken for the HLT selection and its dependence on detector and operating conditions are presented. The HLT performed reliably and helped provide a large dataset. This dataset has proven to be invaluable for understanding the performance of the trigger and the CMS experiment as a whole.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Precise mapping of the magnetic field in the CMS barrel yoke using cosmic rays

This is the Pre-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 IOPThe CMS detector is designed around a large 4 T superconducting solenoid, enclosed in a 12 000-tonne steel return yoke. A detailed map of the magnetic field is required for the accurate simulation and reconstruction of physics events in the CMS detector, not only in the inner tracking region inside the solenoid but also in the large and complex structure of the steel yoke, which is instrumented with muon chambers. Using a large sample of cosmic muon events collected by CMS in 2008, the field in the steel of the barrel yoke has been determined with a precision of 3 to 8% depending on the location.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)

Performance of the CMS drift tube chambers with cosmic rays

This is the Pre-print version of the Article. The official published version of the paper can be accessed from the link below - Copyright @ 2010 IOPStudies of the performance of the CMS drift tube barrel muon system are described, with results based on data collected during the CMS Cosmic Run at Four Tesla. For most of these data, the solenoidal magnet was operated with a central field of 3.8 T. The analysis of data from 246 out of a total of 250 chambers indicates a very good muon reconstruction capability, with a coordinate resolution for a single hit of about 260 μm, and a nearly 100% efficiency for the drift tube cells. The resolution of the track direction measured in the bending plane is about 1.8 mrad, and the efficiency to reconstruct a segment in a single chamber is higher than 99%. The CMS simulation of cosmic rays reproduces well the performance of the barrel muon detector.This work is supported by FMSR (Austria); FNRS and FWO (Belgium); CNPq, CAPES, FAPERJ, and FAPESP (Brazil); MES (Bulgaria); CERN; CAS, MoST, and NSFC (China); COLCIENCIAS (Colombia); MSES (Croatia); RPF (Cyprus); Academy of Sciences and NICPB (Estonia); Academy of Finland, ME, and HIP (Finland); CEA and CNRS/IN2P3 (France); BMBF, DFG, and HGF (Germany); GSRT (Greece); OTKA and NKTH (Hungary); DAE and DST (India); IPM (Iran); SFI (Ireland); INFN (Italy); NRF (Korea); LAS (Lithuania); CINVESTAV, CONACYT, SEP, and UASLP-FAI (Mexico); PAEC (Pakistan); SCSR (Poland); FCT (Portugal); JINR (Armenia, Belarus, Georgia, Ukraine, Uzbekistan); MST and MAE (Russia); MSTDS (Serbia); MICINN and CPAN (Spain); Swiss Funding Agencies (Switzerland); NSC (Taipei); TUBITAK and TAEK (Turkey); STFC (United Kingdom); DOE and NSF (USA)
