Status of the Level-0 ATLAS barrel muon trigger for High-Luminosity LHC
No full textThe Muon Spectrometer of the ATLAS detector will be substantially modified during the Phase-II Upgrade to cope with the higher particle rates and radiation levels of the High-Luminosity LHC. The entire trigger and readout electronics of the Resistive Plates Chambers will be replaced. The Resistive Plate Chambers hit data will be collected by on-detector Data Transmitter and Collector boards and will be sent off-detector to the Sector Logic boards, which will perform the Level-0 barrel muon trigger algorithm and the readout logic. This contribution presents the design of the Phase-II barrel muon trigger and data acquisition system and the developement of the barrel Sector Logic board firmware and its challenges

No full textVariations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Toward 2050: Critical Analysis of Energy and Economic Requirements of Carbon Capture and Storage in Post Combustion Capture
No full textAccording to the International Energy Agency (IEA) Net Zero report of 2023, Carbon Capture and Storage (CCS) is projected to achieve an 8% reduction in cumulative emissions, with an estimated capacity of 6 billion tons per year by 2050. The purpose of this work is to estimate the magnitude of effort required to meet this projection, both from an economic and an energy point of view. Based on the post-combustion process of a combined cycle gas turbine (CCGT) power plant and using Shell-Cansolv proprietary DC-103 solvent as a reference capture agent, an analysis of the energy requirements and economic costs associated with this technology has been conducted. This analysis includes parameters such as the energy surplus required for CO2 capture, Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) of the plant. Costs related to CO2 transport and storage have not been considered. The values obtained, applied to the IEA's climate neutrality goals, are essential for understanding the operational and economic challenges of post-combustion capture. In particular, considering the important role of CCS in the IEA report and considering the calculation made with the reference data, about 5000 plants would need to be built by 2050, equivalent to an average of nearly 200 plants annually. This would require an investment of $1.24 trillion according by the current available technologies. Moreover, an additional energy cost of about 25% for the CCGT plant would be required to capture the CO2 that has been emitted for the power production. This could also result in additional CO2 emissions, thereby reducing the net capture capacity of the system. These data illustrate the scale of commitment required to achieve the ambitious climate-neutrality goals, in which significant amount of economic efforts and energy resources will have to be drawn upon. It also highlights the urgency of investing in more efficient and sustainable CO2 capture technologies and strategies. This study provides quantitative data that can be useful in making informed decisions regarding the adoption and implementation of CCS technologie
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Development of the Barrel Sector Logic firmware of the ATLAS Muon Spectrometer for the High-Luminosity LHC
No full textThe Muon Spectrometer of the ATLAS detector at the Large Hadron Collider will undergo a substantial improvement during the Long Shutdown 3 to cope with the instantaneous luminosity and radiation levels foreseen for the High
Luminosity LHC. The entire trigger and readout electronics of the Resistive Plates Chambers will be replaced. All data coming from these detectors will be collected by the on-detector Data Collector and Transmitter boards and then sent to the off detector Sector Logic boards, which will execute the muon Level-0 trigger algorithm and perform the readout logic. This contribution describes the development of the
barrel Sector Logic firmware and the related challenges
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
