  • Recommended Design Strategies for a Sustainable Library Retrofit

    Cowling, Ethan; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05)
    Using the third floor of the University of Arizona Main Library as a model, this project aimed to identify energy efficiency measures, design strategies to improve occupant comfort, and modernizing library spaces for current functionality. The project identified eight Energy Conservation Recommendations (ECR's) and fourteen Architectural Improvement Recommendations (AIR's). More strategies are identified over the course of this project; however, the following implementations were determined to be the most pertinent for future designers to consider in a library retrofit.
  • Analysis of the Built Environment of Manufactured Housing Communities in Tucson, Arizona

    Sandoval, Myriam; College of Architecture, Planning and Landscape Architecture; Iuliano, Joey (The University of Arizona., 2021-05-14)
    This study will analyze the built environments of three large, manufactured housing communities in Tucson, Arizona. The three communities were chosen using existing research of manufactured housing density in Pima County. With the implementation of a rating system incorporating aspects of the United Nations’ Sustainable Development Goals and the SITES Rating system, the three communities were assessed on several criteria, each on a scale of one to five. The essential problem that the built environment of manufactured communities face is an abundance of asphalt and a lacking green open space and shading. The research question being posed will determine which of the three manufactured communities suffers the most from an abundance of concrete and asphalt. From the analysis, it was determined that two of the manufactured communities, Plaza del Sol and Country Club Manufactured Housing Community, were given the same assessment from the rating system that was utilized to answer the research question. Given the limited rights residents in these communities have over land ownership, it is often challenging to achieve green infrastructure practices in these communities to promote more shading and green open space.
  • Operation and performance of the ATLAS Tile Calorimeter in Run 1

    Aaboud, M.; Aad, G.; Abbott, B.; Abdallah, J.; Abdinov, O.; Abeloos, B.; Abhayasinghe, D. K.; Abidi, S. H.; AbouZeid, O. S.; Abraham, N. L.; et al. (SPRINGER, 2018)
    The Tile Calorimeter is the hadron calorimeter covering the central region of the ATLAS experiment at the Large Hadron Collider. Approximately 10,000 photomultipliers collect light from scintillating tiles acting as the active material sandwiched between slabs of steel absorber. This paper gives an overview of the calorimeter's performance during the years 2008-2012 using cosmic-ray muon events and proton-proton collision data at centre-of-mass energies of 7 and 8 TeV with a total integrated luminosity of nearly 30 fb(-1). The signal reconstruction methods, calibration systems as well as the detector operation status are presented. The energy and time calibration methods performed excellently, resulting in good stability of the calorimeter response under varying conditions during the LHC Run 1. Finally, the Tile Calorimeter response to isolated muons and hadrons as well as to jets from proton-proton collisions is presented. The results demonstrate excellent performance in accord with specifications mentioned in the Technical Design Report.
  • In situ calibration of large-radius jet energy and mass in 13TeVproton-proton collisions with the ATLAS detector

    Aaboud, M.; Aad, G.; Abbott, B.; Abdinov, O.; Abeloos, B.; Abidi, S. H.; Abou Zeid, O. S.; Abraham, N. L.; Abramowicz, H.; Abreu, H.; et al. (SPRINGER, 2019)
    The response of the ATLAS detector to large-radius jets is measured in situ using 36.2 fb(-1) of root s = 13TeV proton-proton collisions provided by the LHC and recorded by the ATLAS experiment during 2015 and 2016. The jet energy scale is measured in events where the jet recoils against a reference object, which can be either a calibrated photon, a reconstructed Z boson, or a system of well-measured small-radius jets. The jet energy resolution and a calibration of forward jets are derived using dijet balance measurements. The jet mass response is measured with two methods: using mass peaks formed by W bosons and top quarks with large transverse momenta and by comparing the jet mass measured using the energy deposited in the calorimeter with that using the momenta of charged-particle tracks. The transverse momentum and mass responses in simulations are found to be about 2-3% higher than in data. This difference is adjusted for with a correction factor. The results of the different methods are combined to yield a calibration over a large range of transverse momenta (p(T)). The precision of the relative jet energy scale is 1-2% for 200 GeV < p(T) < TeV, while that of the mass scale is 2-10%. The ratio of the energy resolutions in data and simulation is measured to a precision of 10-15% over the same p(T) range.
  • Measurements of W and Z boson production in pp collisions at root s=5.02 TeV with the ATLAS detector

    Aaboud, M.; Aad, G.; Abbott, B.; Abdinov, O.; Abeloos, B.; Abhayasinghe, D. K.; Abidi, S. H.; AbouZeid, O. S.; Abraham, N. L.; Abramowicz, H.; et al. (SPRINGER, 2019)
    Measurements of fiducial integrated and differential cross sections for inclusive W +, W -and Z boson production are reported. They are based on 25.0 +/- 0.5 pb -1 of pp collision data at v s = 5.02 TeV collected with the ATLAS detector at the CERN Large Hadron Collider. Electron and muon decay channels are analysed, and the combined W +, W -and Z integrated cross sections are found to be sW+ = 2266 +/- 9 (stat) +/- 29 (syst) +/- 43 (lumi) pb, sW-= 1401 +/- 7 (stat) +/- 18 (syst) +/- 27 (lumi) pb, and sZ = 374.5 +/- 3.4 (stat)+/- 3.6 (syst)+/- 7.0 (lumi) pb, in good agreement with next-to-next-to-leading-order QCD crosssection calculations. Thesemeasurements serve as references for Pb+ Pb interactions at the LHC at v sNN = 5.02 TeV.
