Universal Experimental Measurement System «Sun-Walker» : Automotive measurement system for the evaluation of the solar irradiation distribution for the tests of the solar concentrated systems.

This Thesis project is a part of the research conducted in Solar industry. ABSOLICON Solar Concentrator AB has invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate distribution of density of solar radiation in the focal line of the concentrated parabolic reflectors and to measure radiation from the artificial source of light being a calibration-testing tool.On the basis of the requirements of the company’s administration and needs of designing the concentrated reflectors the operation conditions for the Sun-Walker were formulated. As the first step, the complex design of the whole system was made and division on the parts was specified. After the preliminary conducted simulation of the functions and operation conditions of the all parts were formulated.As the next steps, the detailed design of all the parts was made. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Sun-Walker were assembled and tested. The software part, which controls the Sun-Walker work and conducts measurements of solar irradiation, was created on the LabVIEW basis. To tune and test the software part, the special simulator was designed and assembled.When all parts were assembled in the complete system, the Sun-Walker was tested, calibrated and tuned.

¡Solo vos! : Un estudio sociolingüístico sobre las actitudes hacia el voseo argentino

Resumen En este estudio se analizan las actitudes lingüísticas de un grupo de mujeres argentinas, venezolanas y mexicanas residentes en Qatar, Argentina y Suecia en relación con el voseo argentino. Metodológicamente se utilizan tres técnicas: la primera consiste en grabar dos versiones de un texto leído por una persona de Argentina; en la segunda un grupo de informantes escucha el texto grabado y contestan simultáneamente una encuesta que evalúa su postura con respecto al uso del pronombre vos, así como de sus usuarios; la tercera está dedicada a la entrevista, en la cual se pregunta a las informantes argentinas cuál es su opinión acerca del voseo como sinónimo de identidad lingüística. El análisis de los resultados indica que existe una diferencia significativa entre cómo se juzgan las dimensiones de estatus y solidaridad, ya que las entrevistadas dieron un menor valor a los atributos relacionados con la dimensión de estatus que a los de solidaridad. Resumiendo los resultados, se advierte que las argentinas evalúan más positivamente el uso del vos que el tú, confirmando que tienen una posición positiva sobre su identidad lingüística.
