Casa vertical
Trabajo de gradoEl proyecto CASA VERTICAL está ubicado en Bogotá D. C., en la localidad No. 4 San Cristóbal en el barrio Calvo Sur, Presenta diversas problemáticas socioeconómico espacial y déficit cuantitativo habitacional; el medio normativo como solución es la renovación urbana por redensificación en altura, implementando actividad residencial, tarea que implica la recuperación integral del sector, el mejoramiento de la seguridad, el tráfico, los estacionamientos, el espacio público, la imagen urbana, la dinamización, que contribuyen al mejoramiento de la calidad de vida de los residentes actuales y potenciales. En la presente tesis se quiere mitigar el problema de alta densidad del sector especialmente en áreas residenciales, construyendo viviendas en altura para optimizar el territorio, de estas forma se plantea nuevos espacios públicos para la población, que den solución a la Invasión del espacio público actual y su movilidad tanto peatonal como vehicular. Se pretende generar espacios adecuados para reubicar a los vendedores de ambulantes de la zona que invaden el espacio público especialmente alrededor de los equipamientos de salud, y diseñar nuevos tipos de vivienda económica, que sea innovadora en nuevas técnicas de construcción y tecnologías siendo amables con el medio ambiente.PregradoArquitect
La cabaña vertical. Un proyecto inacabado para una casa en Oropesa, España. Sáenz de Oíza, c. 1967-1977
Si la casa, como es lógico, se encuentra en el centro de cualquier discusión sobre el habitar, la casa del arquitecto tendrá, sin duda, un especial interés en este ámbito. Francisco Javier Sáenz de Oíza tuvo la fortuna de poder vivir gran parte de su vida en casas proyectadas por él mismo. No ocurrió así, sin embargo, en el caso de su tantas veces dibujada casa en Oropesa, que nunca llegó a construir. Cuando en 1992, ya profesor emérito, Oíza tuvo que dar una conferencia acerca de la casa en la Escuela de Arquitectura de Madrid, no enseñó ninguna de aquellas que había podido construir para él, ni siquiera alguna de las que había realizado para sus clientes, sino que rescató del olvido este pequeño refugio desconocido para casi todos. Se trataba de una pequeña cabaña en mitad del bosque. El programa, mínimo, se encontraba verdaderamente ajustado en sus dimensiones y las técnicas constructivas que se proponían incidían en este carácter austero de la vivienda. Sin embargo, la cabaña tenía una particularidad evidente que destacaba por encima de las demás: al contrario de lo que podía esperarse, ésta era una cabaña vertical. Con la reconstrucción gráfica y el análisis de esta pequeña obra intentaremos arrojar algo de luz, de buscar una particular construcción de sentido, a la intensa y poliédrica arquitectura de un hombre tachado en ocasiones de ?navegar a la deriva?, pero sin duda complejo y fascinante
Sources of variations in total column carbon dioxide
Observations of gradients in the total CO_2 column,
(CO2), are expected to provide improved constraints
on surface fluxes of CO_2. Here we use a general circulation
model with a variety of prescribed carbon fluxes to investigate how variations in (CO_2) arise. On diurnal scales, variations are small and are forced by both local fluxes and advection. On seasonal scales, gradients are set by the north-south flux distribution. On synoptic scales, variations arise due to large-scale eddy-driven disturbances of the meridional gradient. In this case, because variations in (CO_2) are tied to synoptic
activity, significant correlations exist between (CO_2)
and dynamical tracers. We illustrate how such correlations
can be used to describe the north-south gradients of (CO_2)
and the underlying fluxes on continental scales. These simulations suggest a novel analysis framework for using column observations in carbon cycle science
A prototype system for detecting the radio-frequency pulse associated with cosmic ray air showers
The development of a system to detect the radio-frequency (RF) pulse
associated with extensive air showers of cosmic rays is described. This work
was performed at the CASA/MIA array in Utah, with the intention of designing
equipment that can be used in conjunction with the Auger Giant Array. A small
subset of data (less than 40 out of a total of 600 hours of running time),
taken under low-noise conditions, permitted upper limits to be placed on the
rate for pulses accompanying showers of energies around eV.Comment: 53 pages, LaTeX, 19 figures, published in Nuclear Instruments and

Thermal analysis and energy-efficient solutions to preserve listed building façades. The INA-Casa building heritage
Energy efficiency of building heritage derived from pre-regulation period is one of the most debated topics in Europe. Building facades, through opaque walls and thermal bridges, are a major source of transmission heat losses and require sustainable and consistent solutions. Aiming to achieve an energy demand reduction, thermal features of building facades were evaluated by field measurements and simulations for one INA-Casa listed apartment building built in the 1950s. Non-destructive insulating solutions have been proposed and a comparison between transmission heat loss coefficient in the current situation and the designed intervention was made. Results show that before the renovation, opaque walls and thermal bridges respectively contributed to 25% and 44% of total transmission heat loss in the case-study building facade. After the renovation, total impact was reduced up to 70% depending on whether high performance windows were replaced; in particular, the impact of opaque walls and thermal bridges were reduced by 66% and 82%, respectively. Interventions performed primarily on the internal layer of the facade with insulation elements, when appropriately designed, strengthen the negative effects of thermal bridges in junctions. Findings show that an accurate insulation design allows for both more efficient conditions and the preservation of the heritage-listed building

Extensive Air Shower Radio Detection: Recent Results and Outlook
A prototype system for detecting radio pulses associated with extensive
cosmic ray air showers is described. Sensitivity is compared with that in
previous experiments, and lessons are noted for future studies.Comment: 17 pages, LaTeX, 7 figures, invited talk presented by J. Rosner at

A New Measurement of Cosmic Ray Composition at the Knee
The Dual Imaging Cerenkov Experiment (DICE) was designed and operated for
making elemental composition measurements of cosmic rays near the knee of the
spectrum at several PeV. Here we present the first results using this
experiment from the measurement of the average location of the depth of shower
maximum, , in the atmosphere as a function of particle energy. The value
of near the instrument threshold of ~0.1 PeV is consistent with
expectations from previous direct measurements. At higher energies there is
little change in composition up to ~5 PeV. Above this energy is deeper
than expected for a constant elemental composition implying the overall
elemental composition is becoming lighter above the knee region. These results
disagree with the idea that cosmic rays should become on average heavier above
the knee. Instead they suggest a transition to a qualitatively different
population of particles above 5 PeV.Comment: 7 pages, LaTeX, two eps figures, aas2pp4.sty and epsf.sty included,

Materials and techniques of Art Nouveau architecture in Italy and Portugal: a first insight for an European route to consistent restoration
The results of the investigations on building materials and techniques of Casa Major Pessoa, a typical Art
Nouveau construction in Aveiro (Portugal), and two coeval Art Nouveau buildings in Bologna (Italy) are presented
as a methodological contribution to the restoration of this kind of buildings. This is the first step to
ascertain the existence of a common thread between local materials, technologies and architecture in European
countries at the same period. A holistic approach was adopted: materials were investigated along with
architectural, structural and technological features, in order to achieve a first insight into the Art Nouveau
architecture in Europe in particular for its consistent restoration without loss of historical memory
