Relación dialógica emergente para la gestión y ordenamiento del territorio. Exploración de eco-proyectos en el borde oeste de la ciudad de Córdoba en su interfase urbana-metropolitana

Ponencia presentada en la 53º IFLA World Congress International Federation of Landascape Architects. Tasting the Landscape. Torino, Italia. 2016El estudio hace énfasis en los Paisajes del Borde, particularizando en el Borde Oeste de la Ciudad de Córdoba, República Argentina, en su interfase con el área metropolitana y su relación con las Infraestructuras en una escala urbano-territorial como medio de reconciliación entre la arquitectura, la ciudad y el territorio. Se reconoce la interacción dialógica Paisaje e Infraestructura y en particular a las Infraestructuras Verdes constituida por una red interconectada de paisajes de valor ambiental, cultural y visual que conforman una estructura ecológica, básica y compleja, que estructuran el territorio y traspasan las áreas de fronteras entre el campo, la ciudad, y los límites jurisdiccionales constituyendo un sistema de ordenadores en el paisaje y una herramienta posible para la gestión y el ordenamiento del territorio. El proyecto en ese marco, contempla la redefinición de las infraestructuras urbanas como una hibridación de infraestructuras verdes y la valoración de los paisajes que las contienen, a través de un estudio que permita la elaboración de catálogos de paisaje con sus variantes e invariantes y la realización de ensayos donde dialoguen el paisaje y la infraestructuras con exploraciones de hibridación redefiniendo las infraestructuras urbanas como soportes de Eco-proyectos y como medio de reconciliación entre la naturaleza y el artificio.Fil: Álvarez, Teresita.

Interlaboratory proficiency testing of tensile and flexural testing for cellulose based transformed board material

Optimum safety and reliability can be achieved by coordinating an interlaboratory proficiency testing among different laboratories. Testing laboratories need to verify their test procedures and testing capability for reliable results. In this study, equivalent samples are prepared by cellulose based transformed board material used in transformers as electrical isolation material. Randomly selected test samples having specified dimensions are sent to the participant laboratories. Then they are tested and results are analyzed according to previously defined parameters. Each laboratory applied tensile and flexural tests on the samples according to procedures given in IEC 60641-2, 2004 and IEC 60763-2, 2007 standards respectively. Test results are evaluated according to same procedures explained in related standards by the participant laboratories. TUBITAK UME Material Testing Laboratory being the pilot laboratory collected to the all evaluated results including associated measurement uncertainties. Then the collected results evaluated according to ISO 17043, 2010 are reported by each laboratory as a part of the proficiency test report. Z-scores of the participant laboratories are presented

Calculation of measurement uncertainty for cellulose based transformed board material in tensile testing

Today’s global economy obliges manufacturers to produce their products in high quality with cheaper cost. Thus, manufacturers must develop their products applying tests to get better performance and higher quality before distributing them to the competitive market. In order to produce long working life of transformer reactors without losing their performance, different tests including axial and flexural testing are applied on the cellulose based laminated board material used in production. During development of laminated board material, test results should be known very well and the measurement uncertainty of tensile tests should be calculated taking into account all parameters. In this study, effective parameters on the quality of tensile testing causing an increase on the measurement uncertainty are investigated. Tensile strength and elongation test of laminated board material were carried out according to IEC 60641-2 and the uncertainty contributions based on experimental results were calculated. The results and impact of the uncertainty parameters are presented in detail

Calculation of measurement uncertainty for plastic (ABS) material in flexural testing

In order to determine mechanical properties of materials various kind of tests can be applied by means of using their tensile strength, lower yield stress, proof stress, impact strength, Brinell, Rockwell and surface hardness, elongation after fracture properties. Among these tests, three point flexural testing method has some advantages such as easy preparation (production) of samples and no gripping problems comparing to tension test. Flexural tests results should be obtained accurately to provide expected testing performance. The measurement uncertainty of flexural tests should be calculated by conducting all effective uncertainty parameters during the test procedure. In this study, the measurement uncertainty of the flexural test of ABS (Acrylonitrile Butadiene Styrene) material was investigated, which is widely used as industrial plastic material in many applications

A comprehensive filtering scheme for high-resolution estimation of the water balance components from high-precision lysimeters

Large weighing lysimeters are currently the most precise method to directly measure all components of the terrestrial water balance in parallel via the built-in weighing system. As lysimeters are exposed to several external forces such as management practices or wind influencing the weighing data, the calculated fluxes of precipitation and evapotranspiration can be altered considerably without having applied appropriate corrections to the raw data. Therefore, adequate filtering schemes for obtaining most accurate estimates of the water balance components are required. In this study, we use data from the TERENO (TERrestrial ENvironmental Observatories) SoilCan research site in Bad Lauchstädt to develop a comprehensive filtering procedure for high-precision lysimeter data, which is designed to deal with various kinds of possible errors starting from the elimination of large disturbances in the raw data resulting e.g., from management practices all the way to the reduction of noise caused e.g., by moderate wind. Furthermore, we analyze the influence of averaging times and thresholds required by some of the filtering steps on the calculated water balance and investigate the ability of two adaptive filtering methods (the adaptive window and adaptive threshold filter (AWAT filter; Peters et al., 2014), and a new synchro filter applicable to the data from a set of several lysimeters) to further reduce the filtering error. Finally, we take advantage of the data sets of all 18 lysimeters running in parallel at the Bad Lauchstädt site to evaluate the performance and accuracy of the proposed filtering scheme. For the tested time interval of 2 months, we show that the estimation of the water balance with high temporal resolution and good accuracy is possible. The filtering code can be downloaded from the journal website as Supplement to this publication

High-resolution estimation of the water balance components from high-precision lysimeters

Lysimeters offer the opportunity to determine precipitation, evapotranspiration and groundwater-recharge with high accuracy. In contrast to other techniques, like Eddy-flux systems or evaporation pans, lysimeters provide a direct measurement of evapotranspiration from a clearly defined surface area at the scale of a soil profile via the built-in weighing system. In particular the estimation of precipitation can benefit from the much higher surface area compared to typical raingauge systems. Nevertheless, lysimeters are exposed to several external influences that could falsify the calculated fluxes. Therefore, the estimation of the relevant fluxes requires an appropriate data processing with respect to various error sources. Most lysimeter studies account for noise in the data by averaging. However, the effects of smoothing by averaging on the accuracy of the estimated water balance is rarely investigated. In this study, we present a filtering scheme, which is designed to deal with the various kinds of possible errors. We analyze the influence of averaging times and thresholds on the calculated water balance. We further investigate the ability of two adaptive filtering methods (the Adaptive Window and Adaptive Threshold filter (AWAT-filter) (Peters et al., 2014) and the consecutively described synchro-filter) in further reducing the filtering error. On the basis of the data sets of 18 simultanously running lysimeters of the TERENO SoilCan research site in Bad Lauchstädt, we show that the estimation of the water balance with high temporal resolution and good accuracy is possible
