Measurement of the electron anti-neutrino cross-section on carbon at the T2K near detector
No full textThe intrinsic electron anti-neutrino component in the muon anti-neutrino Tokai to Kamiokande (T2K) beam represents the largest irreducible background for the muon anti-neutrino to the electron anti-neutrino appearance measurement at Super-Kamiokande.
In this thesis, the electron anti-neutrino charged-current inclusive cross-section on carbon is measured using the T2K near detector (ND280).
The measurement is performed in two steps: the selection of the electron anti-neutrino events, and the correction of the detector inefficiency and mis-reconstruction (unfolding).
In the selection step, a new particle identification based on the Boosted Decision Tree (BDT) was developed. The Particle IDentifications (PIDs) from the Fine-Grained Detectors (FGDs), Time Projection Chambers (TPCs) and Electromagnetic Calorimeters (ECALs) are used as input for the BDT to select the positron track; a characteristic feature of the charged-current interaction of the electron anti-neutrino.
The BDT parameters were tuned to maximize the selection efficiency, purity and Kolmogorov-Smirnov (KS) test. The uncertainty on the BDT output test statistic was calculated by propagating the input variables systematics using Monte Carlo (MC) simulation.
Moreover, we have developed an improved unfolding algorithm based on the D'Agostini 2010 method as well as a framework to test the unfolding performance.
In order to to constrain the gamma background, we have also constructed a control sample to select the gamma events and to use it in the simultaneous unfolding framework.
Finally, we measured the electron anti-neutrino charged-current inclusive cross-section on carbon with and without using the control sample.February 201
Place of Unpretentiousness: Non-commercial architecture
No full textThe public condenser tends to stress the importance of non-commercial architecture within the context of Copenhagen as an opposition to the concept of consumerism. According to Leslie Sklair (2010): “Consumerism - or more accurately, the culture-ideology of consumerism - refers to a set of beliefs and values, integral but not exclusive to the system of capitalist globalization, intended to make people believe that human worth is best ensured and happiness is best achieved in terms of our consumption and possessions.”In addition to that, according to ‘The Harvard Guide to Shopping’ by Rem Koolhaas, “Shopping is arguably the last remaining form of public activity”, and “perhaps the beginning of the 21st century will be remembered as the point where the urban could no longer be understood without shopping.” Nowadays shopping is taking over every program imaginable. As a parasite it attaches itself to different programs, finding ways to survive and dominate, invading almost all human activity (Leong, 2001). Through psychoanalysis and psychogramming, people are being manipulatively forced to consume even more for the sake of making economic profit (Hosoya & Schaefer, 2001).The fact that one of nowadays most common public activity in gathering people is been led by manipulative strategies is shocking and urges to consider a place for the public that does not intend to manipulate for the sake of making economic profit. Therefore the public condenser in Copenhagen provides a place in which multiple activities can take place for different target audiences, not for the sake of making profit, but for the sake of providing valuable and unique experiences to the public in complete honesty, trustworthiness and transparency. Here, value refers to the immaterial profit as a counter reaction on consumerism while uniqueness refers to the extraordinary activities that can be achieved without the need of extravagancy. Honesty and trustworthiness refer to the anti-manipulative character of the building, while transparency refers to its straightforwardness and (visual) permeability.The Public CondenserArchitecture, Urbanism and Building Science
The Politics of Passing: Disabled and Mad Students’ Experiences of Disclosure in Higher Education
No full textThis dissertation explores disabled and mad students experiences of disclosure in higher education from a Deleuzian new materialist perspective. This theoretical orientation conceptualized students’ movements through the university as rhizomatic, and included passing, moving into the middle, and coming out. The author argues that these movements create an affective politics within the university that can change and rearrange the university in meaningful ways for individuals with embodied differences.
The author organizes the relationship between students and the university using la paperson’s (2017) idea that there are two competing machinic-desires operating within higher education. In this thesis, these desires are defined as eugenic and crip. Eugenic desires operate within the university and construct assemblages with eugenic ends and are operationalized by the disclosure process. Crip desires, on the other hand are a passional understanding of disability and madness as multiplicity (rather than a binary) that can build the university anew. Crip desires are constituted by disabled and mad students and create assemblages that deterritorialize the university.
The impact of disclosure was made clear by the 17 disabled and mad participants who shared stories of disclosure’s affective violence (when registering as a “student with a disability,” or disclosing to faculty or staff, and petitioning a grade or a course). The author argues that disclosure produces violence in higher education because it reduces embodied differences to biomedical and psychiatric explanations – often limiting disability/madness from becoming anything other. However, there are other ways that students speak about disability and move in-between identities that allow for a different understanding of disability and madness to emerge. When students come out-crip, they story difference rather than disclose disability, and therefore, create new conditions for how access might be arranged. The author argues that a more complex understanding of students’ movements and actions as rhizomatic reveals that they are engaged in micropolitical work with identity that can create small and slow cracks in the university. In asking participants to imagine a different university, this project engages in a thinking-resistance that works towards actualizing different conditions for learning in higher education.Ph.D.2021-10-30 00:00:0

University of Cincinnati, Department of Civil and Architectural Engineering and Construction Management"--Technical report documentation page.; "Author(s) ... Mohamed M. Ahmed, Fady Reyad, Ahmed Mohamed, Jacob Wroten"--Technical report documentation page.; "Prepared in cooperation with the Ohio Department of Transportation and the U.S. Department of Transportation, Federal Highway Administration"--Page iii.; Additional information provided in email: Sate job number 136675.;Final report (vii, 19 pages) -- [Fact sheet] (2 unnumbered pages)This study investigated practices, systems, and tools utilized in the US to assess the congestion impact of multiple construction projects occurring simultaneously on the same route or parallel corridors. The project conducted a national scan of the literature, and an online survey followed by agency outreach via phone interviews. The primary objectives of the project were to: (1) identify the practices employed by state DOTs to quantify congestion resulting from multiple construction projects, (2) determine the conditions that trigger congestion assessments, and the associated Measures of Effectiveness (MOEs) used, and (3) identify strategies to optimize resource utilization while minimizing the impact of construction-related congestion. The project results revealed that a limited number of state DOTs systematically assess the congestion impact of multiple construction projects. Identified state DOTs use a continuum of traffic analysis tools, from basic ones such as the Highway Capacity Manual (HCM) and sketch-planning, travel demand models, to more resource-intensive complex ones such as macro-, meso-, and microsimulation software. Among those state DOTs, impact of individual projects is assessed, and Engineering Judgment is used to compound the effect of multiple projects. Multiple states are currently exploring data-driven approaches utilizing Smart Work Zone (SWZ), Work Zone Data Exchange (WZDx), INRIX, Streetlight, and BlueTOAD to assess congestion impact of construction projects. Further studies should be conducted to investigate when complex tools should be utilized, and to assess the costs and savings of developing and deploying systematic processes identified in this report
Ascended Jesus and Cultic Atonement: Reading Luke-Acts within Second Temple Judaism
No full textIn this dissertation, I examine the role of the Jerusalem temple in Luke-Acts, arguing for its positive depiction and centrality in cultic worship. While Lukan scholarship has recognized the temple's significance, its implications for worship practices have not been fully explored. This study demonstrates that the temple remains vital in Luke-Acts, in the ministries of Jesus, the twelve disciples, and Paul. A major focus is on sacrificial practices within the temple, where Luke presents the Jerusalem temple as the rightful place for these rituals. The dissertation dissects the Levitical sacrificial system, emphasizing the roles of specific offerings in achieving atonement. The purification process described involves both the temple and the worshipper, highlighting the restoration of their relationship with God. Using Umberto Eco's semiotic theory, especially concerning the cultural encyclopedia of texts, I explore the concept of the heavenly temple in Second Temple Judaism. I show that while Luke does not explicitly mention the heavenly temple, his language reflects a shared conceptual and cultural vocabulary with other early Jewish authors. Ultimately, the dissertation posits that Jesus's ascension represents a sacrificial act that facilitates the purification of both Jews and Gentiles, fulfilling prophetic traditions. Luke's subtle sacrificial language suggests an expectation that his audience would recognize these connections, situating Jesus within a broader sacrificial framework and underscoring the text's deep roots in early Jewish context.DissertationDoctor of Philosophy (PhD)In this dissertation, I explore how the author of Luke-Acts sees Jesus as an atoning sacrifice that enables repentance and brings forgiveness of sins, similar to ideas found in other early Jewish writings from the time. By viewing atonement as a way to purify the temple and recognizing the early Jewish concept of a heavenly temple, I aim to clarify the role of atonement in Luke-Acts

The long-term performance of a bituminous geomembrane (BGM) under single-sided exposure conditions
No full textA custom-designed apparatus (referred to as the Ageing Column) is used to age a 4.8-mm thick elastomeric bituminous geomembrane (BGM) under single-sided exposure to a synthetic municipal solid waste (MSW) leachate and a synthetic high pH mining solution (pH 11.5) at 55, 70, and 85°C. This apparatus involves a closer simulation of the BGM’s chemical exposure conditions in the field than the double-sided immersion tests in which the BGM is exposed to the solution from both surfaces. The mechanical, rheological, and chemical properties of the BGM are examined to assess the degradation in the BGM components relative to double-sided immersion experiments. While the single-sided ageing of the BGM reduces the degradation rates in the BGM mechanical properties, it does not affect the degradation rate of the bitumen coat relative to the double-sided exposure. Additionally, the exposure of the BGM to the MSW leachate resulted in faster degradation in its mechanical properties but slower degradation in the bitumen coat than that obtained in the exposure to the mining solution. However, predictions of the time to nominal failure of the BGM established using Arrhenius modelling at different temperatures show that the temperature effect is more significant on the BGM durability than the chemistry of the considered solutions.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Direct numerical simulations of separated and separated-reattaching flows on massively parallel processing computers
No full textDirect numerical simulations of separated-reattaching and separated flows have been performed on massively parallel processing computers. Two basic geometrical configurations have been studied: the separated-reattaching flow past a normal flat plate with an attached downstream splitter plate and the separated flow past a flat plate held normal to a uniform stream. A high-order finite-difference formulation on collocated grids has been developed to perform unsteady fluid flow simulations in rectangular geometries. The numerical procedure is based on a fifth-order upwind-biased scheme for the convective terms and a fourth-order accurate stencil for the diffusive terms. A direct solver based on eigenvalue decomposition has been developed for the pressure-Poisson equation. A mixed Fourier-spectral/finite-difference formulation is used for the spanwise discretization, and a data-parallel algorithm has been developed for the CM-5. The performance of the algorithm has been evaluated on various grid sizes in model flow problems and for different partition sizes.The characteristics of the separated-reattaching flow have been investigated through two-dimensional simulations in the steady and unsteady regimes. The shedding mechanism is characterized by two major modes at Re = 250 and a single mode at Re = 375 and 500. Further, the instability of the separated shear layer is found to be consistent with inviscid theory. For the two-dimensional study of the separated flow past a normal flat plate, the time-mean flow quantities are observed to be over-estimated compared to the experiments. The time-mean drag coefficient is also over-predicted by a factor of up to 2. This is attributed to the high coherence of the vortices predicted by the two-dimensional simulations. Two interaction regions have been identified in the far wake for Re = 500 and 1000 and are observed to occur pseudo-periodically.Large-scale computations of the three-dimensional separated flow have also been carried out. The flow is seen to break down into small-scale structures and the spanwise development of these structures has been studied. Streamwise ribs and spanwise rolls are identified in the near wake through visualization techniques. The presence of these coherent structures corroborates the experimental observations and numerical calculations for mixing layers and wakes of circular cylinders. The time-mean velocities and Reynolds stresses are found to agree well with the experiments conducted at higher Reynolds numbers.Made available in DSpace on 2011-05-07T13:15:33Z (GMT).

Longevity of Multi-layered Textured HDPE Geomembranes in Low-level Waste Applications
No full textThe degradation behaviour of five multilayered textured white geomembranes (GMBs) is investigated when immersed in two synthetic low-level waste (LLW) leachates with pH 7 and 9 at a range of temperatures (40-85oC) for 48-55 months. Results are compared to the performance of the GMBs in synthetic municipal solid waste (MSW) leachate. Increasing pH from 7 to 9 gives slightly faster antioxidant depletion in LLW leachate. The estimated time to nominal failure for the GMBs is at least 20% longer in LLW leachate than in MSW leachate containing surfactant that accelerates both antioxidant depletion and stress cracking. Thus, MSW leachate can be used as a conservative proxy to estimate the service-life of a GMB in contact with LLW leachate. Two GMBs are considered very highly likely to meet the required 550-year design life of the near surface disposal facilities even based on the most conservative prediction of the time to nominal failure for the GMBs.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.
