Diseño de un edificio de concreto armado de 7 niveles

En este trabajo se realizó el análisis y diseño estructural de un edificio multifamiliar de siete pisos y un semisótano, ubicado en el distrito de San Borja, sobre un terreno con una capacidad portante de 30 tonm2. Como tema complementario se estudió la respuesta del edificio a dos acelerogramas peruanos de sismos recientes. El sistema de techado utilizado es de losas aligeradas con viguetas prefabricadas tipo Firth y losas macizas. El sistema estructural consiste en muros de corte, combinados con pórticos de columnas y vigas de concreto armado, En el semisótano se cuenta con muros de concreto armado en todo el perímetro para resistir los empujes de tierras. Los muros fueron predimensionados de tal manera que el 80 de la fuerza cortante sísmica de diseño del análisis estático, sea resistida únicamente por el concreto, mientras que para predimensionar las columnas solo se considero la carga axial.Tesi

Proyecto condominio El Olivar – 2da y 3ra etapa

La presente tesis tiene como objetivo desarrollar un proyecto de vivienda social en el distrito de Carabayllo, que signifique un cambio al producto ofrecido en la 1era Etapa. La 1era etapa, consistió en 60 departamentos de 60.89 m2 y 26 casas de 111.86 m2, sala de usos múltiples, cancha de fulbito y juego para niños; sin embargo, la alta competencia que se desarrolló en el distrito durante la ejecución del proyecto 2014-2015, así como un producto que no se ajustó a las necesidades del público objetivo hicieron que las ventas no fueran las previstas, por lo que a la fecha aún se tienen disponibles 12 departamentos y 7 casas, siendo la 1era etapa inviable económicamente. De esa manera, surge el proyecto Condominio El Olivar 2da y 3ra Etapa renovado, en el que se decide cambiar el producto inicialmente ofrecido y dirigirlo hacia viviendas de interés social subvencionadas por el Estado, que consiste en un mix de viviendas del programa “Techo Propio” y el “Fondo Mivivienda”, considerando un igual porcentaje de viviendas por cada tipo, asegurando así un mayor velocidad de venta para el programa Mi Vivienda y una mayor rentabilidad con las viviendas del Fondo Mi Vivienda. Para lograr dicho objetivo, como primer punto de partida, se realizará el análisis de situación y su proyección temporal del macroentorno, analizando variables como situación de los mercados internacionales, el ciclo económico mundial y la situación política, económica, empresarial en el Perú. Asimismo, se analizará el microentorno donde se evalúa la investigación de mercado realizada, la influencia de las autoridades municipales en el proyecto, la competencia, los actores relevantes para la empresa y la situación actual del plan de marketing. También se definirán los objetivos del plan estratégico de marketing que están relacionados con el aumento de la velocidad de ventas y la rentabilidad del proyecto. En segundo lugar, se detallará el plan de marketing del proyecto y se definirá la segmentación y target del proyecto que comprende; familias jóvenes que vivan el Cono Norte, en una vivienda alquilada o familiar no propia, cuyos jefes de familia pueden ser profesionales o no profesionales en el rango de 25 a 40 años de edad, con uno o dos hijos pequeños, pertenecientes al nivel socioeconómico C y D, con ingresos familiares promedio de S/3,500.00 y que sean potencialmente elegibles por el sistema financiero para acceder a un crédito hipotecario. Además, Natturale Inmobiliaria, con este proyecto, se pretende posicionar en la mente del consumidor como una empresa socialmente responsable que brinde a sus clientes productos de buena calidad a precios accesibles, con una arquitectura moderna, distribución funcional y buenos acabados en la zona de Carabayllo, sacando provecho al potencial crecimiento de dicho distrito. También, se desarrollará el marketing mix del proyecto analizando las diferentes variables de producto, precio, plaza y promoción. Finalmente, la inversión total del proyecto será de S/. 29,311,486 que incluyen todos los gastos directos e indirectos hasta la finalización y comercialización de este. Este monto estará compuesto por aportes de capital de los accionistas de las preventas, así como de la línea de crédito proporcionada por el Banco BBVA, dentro del Convenio Marco, dado que es la entidad financiera que promueve el proyecto inmobiliario. El proyecto tendrá una duración de 46 meses desde la firma del contrato con las partes involucradas hasta la entrega de los departamentos. El proyecto tendrá una utilidad proyectada después de impuestos S/. 4,063,514. El margen neto sobre ventas sobre las ventas (ROS) será de 12.2% y un VAN de S/. 2,613,843.Tesi

The DUNE Far Detector Vertical Drift Technology, Technical Design Report

International audienceDUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase. It will also stand ready to observe supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector implements liquid argon time-projection chamber (LArTPC) technology, and combines the many tens-of-kiloton fiducial mass necessary for rare event searches with the sub-centimeter spatial resolution required to image those events with high precision. The addition of a photon detection system enhances physics capabilities for all DUNE physics drivers and opens prospects for further physics explorations. Given its size, the far detector will be implemented as a set of modules, with LArTPC designs that differ from one another as newer technologies arise. In the vertical drift LArTPC design, a horizontal cathode bisects the detector, creating two stacked drift volumes in which ionization charges drift towards anodes at either the top or bottom. The anodes are composed of perforated PCB layers with conductive strips, enabling reconstruction in 3D. Light-trap-style photon detection modules are placed both on the cryostat's side walls and on the central cathode where they are optically powered. This Technical Design Report describes in detail the technical implementations of each subsystem of this LArTPC that, together with the other far detector modules and the near detector, will enable DUNE to achieve its physics goals

Impact of cross-section uncertainties on supernova neutrino spectral parameter fitting in the Deep Underground Neutrino Experiment

International audienceA primary goal of the upcoming Deep Underground Neutrino Experiment (DUNE) is to measure the O(10)  MeV neutrinos produced by a Galactic core-collapse supernova if one should occur during the lifetime of the experiment. The liquid-argon-based detectors planned for DUNE are expected to be uniquely sensitive to the νe component of the supernova flux, enabling a wide variety of physics and astrophysics measurements. A key requirement for a correct interpretation of these measurements is a good understanding of the energy-dependent total cross section σ(Eν) for charged-current νe absorption on argon. In the context of a simulated extraction of supernova νe spectral parameters from a toy analysis, we investigate the impact of σ(Eν) modeling uncertainties on DUNE’s supernova neutrino physics sensitivity for the first time. We find that the currently large theoretical uncertainties on σ(Eν) must be substantially reduced before the νe flux parameters can be extracted reliably; in the absence of external constraints, a measurement of the integrated neutrino luminosity with less than 10% bias with DUNE requires σ(Eν) to be known to about 5%. The neutrino spectral shape parameters can be known to better than 10% for a 20% uncertainty on the cross-section scale, although they will be sensitive to uncertainties on the shape of σ(Eν). A direct measurement of low-energy νe-argon scattering would be invaluable for improving the theoretical precision to the needed level

First Measurement of the Total Inelastic Cross-Section of Positively-Charged Kaons on Argon at Energies Between 5.0 and 7.5 GeV

International audienceProtoDUNE Single-Phase (ProtoDUNE-SP) is a 770-ton liquid argon time projection chamber that operated in a hadron test beam at the CERN Neutrino Platform in 2018. We present a measurement of the total inelastic cross section of charged kaons on argon as a function of kaon energy using 6 and 7 GeV/$c$ beam momentum settings. The flux-weighted average of the extracted inelastic cross section at each beam momentum setting was measured to be 380$\pm$26 mbarns for the 6 GeV/$c$ setting and 379$\pm$35 mbarns for the 7 GeV/$c$ setting
