An Analysis of the Influence of Students´ Technological Culture on Their Technology

decade has raised the interest among the research community on the acceptance and use of these systems by both teachers and students. At first, the implementation of LMS was based on their technical design and the adaptation of the learning processes to the virtual environment, neglecting students’ characteristics when the systems were deployed, which led to expensive and failing implementations. The Unified Theory of Acceptance and Use of Technology (UTAUT) proposes a framework which allows the study of the acceptance and use of technology that takes into consideration the students’ characteristics and how they affect the acceptance and the degree of use of educational technology. This study questions the role of the user’s attitude towards use of LMS and uses the UTAUT to examine the moderating effect of technological culture in the adoption of LMS in Spain. The results from the comparison and analysis of three different models confirm the relevance of attitude towards use as an antecedent of intention to use the system, as well as the important moderating effect of gender and technological culture. The discussion of results suggests the need for a more in-depth analysis and interrelations of cultural dimensions in the adoption of educational technologies and learning management systems

The lexical needs of ESP students in a professional field

This paper examines two kinds of questions relating to the lexical needs of professional ESP students: (1) what range of terms and words do they need help with? (2) what types of dictionary, bilingual and/or monolingual, can they make use of in solving lexical problems?

Finite Element Analysis Model of a Contactless Transformer for Battery Chargers in Electric Vehicles

A contactless transformer model is proposed in this paper using Finite Element Analysis (FEA). This model can be used to simulate Inductive Coupling Power Transfer (ICPT) systems with good accuracy of the transformer and reduce the fabrication time of these systems. The model not only takes into account the geometry of the windings but also the frequency effects in them. As the transformer does not have a magnetic core, it is complicated to model because the flux is expanded in the area around the windings. In order to obtain a very accurate model, it is necessary to use a 2D/3D field solver.

FocusDET, a new toolbox for SISCOM analysis. Evaluation of the registration accuracy using monte carlo simulation

Subtraction of Ictal SPECT Co-registered to MRI (SISCOM) is an imaging technique used to localize the epileptogenic focus in patients with intractable partial epilepsy. The aim of this study was to determine the accuracy of registration algorithms involved in SISCOM analysis using FocusDET, a new user-friendly application. To this end, Monte Carlo simulation was employed to generate realistic SPECT studies. Simulated sinograms were reconstructed by using the Filtered BackProjection (FBP) algorithm and an Ordered Subsets Expectation Maximization (OSEM) reconstruction method that included compensation for all degradations. Registration errors in SPECT-SPECT and SPECT-MRI registration were evaluated by comparing the theoretical and actual transforms. Patient studies with well-localized epilepsy were also included in the registration assessment. Global registration errors including SPECT-SPECT and SPECT-MRI registration errors were less than 1.2 mm on average, exceeding the voxel size (3.32 mm) of SPECT studies in no case. Although images reconstructed using OSEM led to lower registration errors than images reconstructed with FBP, differences after using OSEM or FBP in reconstruction were less than 0.2 mm on average. This indicates that correction for degradations does not play a major role in the SISCOM process, thereby facilitating the application of the methodology in centers where OSEM is not implemented with correction of all degradations. These findings together with those obtained by clinicians from patients via MRI, interictal and ictal SPECT and video-EEG, show that FocusDET is a robust application for performing SISCOM analysis in clinical practice.

Development of a model of cross-curricular competencies of students at the Technical University of Madrid

It is known that cross-curricular competences are required for main companies all over the world to be part of our university graduates as technical knowledge does. That is the reason which has led the university structure to include these competences in the every degree curriculo validated since the European Higher Education Area (EHEA)was introduced in the Spanish university context. But the way used for incorporating them has been developed without the necessary guidelines to generate a qualified model.

Climatic analysis methodology of vernacular architecture

Vernacular architecture has demonstrated its perfect environmental adaptation through its empirical development and improvement by generations of user-builders. Nowadays, the sustainability of vernacular architecture is the aim of some research projects in which the same method should be applied in order to be comparable. Hence, we propose a research method putting together various steps. Through the analysis of geographical, lithology, economic, cultural and social influence as well as materials and constructive systems, vernacular architecture is analyzed. But, all this information is put together with the natural landscape (topography and vegetation) and the climatic data (temperature, winds, rain and sun exposure). In addition, the use of bioclimatic charts, such as Olgyay or Givoni’s, revealed the necessities and strategies in urban and building design. They are satisfied in the vernacular architecture by the application of different energy conservation mechanisms, some of them are shown by different examples in this paper.

Geometrical characterization of undisturbed soil samples using X-ray computed tomography image analysis. Effect of soil management on soil structure

El estudio de la estructura del suelo es de vital importancia en diferentes campos de la ciencia y la tecnología. La estructura del suelo controla procesos físicos y biológicos importantes en los sistemas suelo-planta-microorganismos. Estos procesos están dominados por la geometría de la estructura del suelo, y una caracterización cuantitativa de la heterogeneidad de la geometría del espacio poroso es beneficiosa para la predicción de propiedades físicas del suelo. La tecnología de la tomografía computerizada de rayos-X (CT) nos permite obtener imágenes digitales tridimensionales del interior de una muestra de suelo, proporcionando información de la geometría de los poros del suelo y permitiendo el estudio de los poros sin destruir las muestras. Las técnicas de la geometría fractal y de la morfología matemática se han propuesto como una poderosa herramienta para analizar y cuantificar características geométricas. Las dimensiones fractales del espacio poroso, de la interfaz poro-sólido y de la distribución de tamaños de poros son indicadores de la complejidad de la estructura del suelo. Los funcionales de Minkowski y las funciones morfológicas proporcionan medios para medir características geométricas fundamentales de los objetos geométricos tridimensionales. Esto es, volumen, superficie, curvatura media de la superficie y conectividad. Las características del suelo como la distribución de tamaños de poros, el volumen del espacio poroso o la superficie poro-solido pueden ser alteradas por diferentes practicas de manejo de suelo. En este trabajo analizamos imágenes tomográficas de muestras de suelo de dos zonas cercanas con practicas de manejo diferentes. Obtenemos un conjunto de medidas geométricas, para evaluar y cuantificar posibles diferencias que el laboreo pueda haber causado en el suelo. ABSTRACT The study of soil structure is of vital importance in different fields of science and technology. Soil structure controls important physical and biological processes in soil-plant-microbial systems. Those processes are dominated by the geometry of soil pore structure, and a quantitative characterization of the spatial heterogeneity of the pore space geometry is beneficial for prediction of soil physical properties. The technology of X-ray computed tomography (CT) allows us to obtain three-dimensional digital images of the inside of a soil sample providing information on soil pore geometry and enabling the study of the pores without disturbing the samples. Fractal geometry and mathematical morphological techniques have been proposed as powerful tools to analyze and quantify geometrical features. Fractal dimensions of pore space, pore-solid interface and pore size distribution are indicators of soil structure complexity. Minkowski functionals and morphological functions provide means to measure fundamental geometrical features of three-dimensional geometrical objects, that is, volume, boundary surface, mean boundary surface curvature, and connectivity. Soil features such as pore-size distribution, pore space volume or pore-solid surface can be altered by different soil management practices. In this work we analyze CT images of soil samples from two nearby areas with contrasting management practices. We performed a set of geometrical measures, some of them from mathematical morphology, to assess and quantify any possible difference that tillage may have caused on the soil.

Selection, training and validation process of a sensory panel for bread analysis: Influence of cultivar on the quality of breads made from common wheat and spelta wheat

A protocol of selection, training and validation of the members of the panel for bread sensory analysis is proposed to assess the influence of wheat cultivar on the sensory quality of bread. Three cultivars of bread wheat and two cultivars of spelt wheat organically-grown under the same edaphoclimatic conditions were milled and baked using the same milling and baking procedure. Through the use of triangle tests, differences were identified between the five breads. Significant differences were found between the spelt breads and those made with bread wheat for the attributes ?crumb cell homogeneity? and ?crumb elasticity?. Significant differences were also found for the odor and flavor attributes, with the bread made with ?Espelta Navarra? being the most complex, from a sensory point of view. Based on the results of this study, we propose that sensory properties should be considered as breeding criteria for future work on genetic improvement.

Evaluación de la pertinencia de maestrías en ingeniería : aplicación en la Universidad de Piura, Perú

La formación de postgrado en ingeniería es muy importante para mejorar la competitividad y lograr el desarrollo en los países. Para ello es necesaria una fuerte vinculación de la universidad con su entorno socio económico de modo que los objetivos que se plantea en sus programas formativos sean coherentes con las necesidades reales de los beneficiarios: los estudiantes, la universidad y la comunidad. Es decir, los programas deben ser pertinentes. Y en los países en vías de desarrollo este tema es aún más importante. Se necesita modelos de evaluación que midan este grado de adecuación entre los objetivos de los programas con las necesidades de los estudiantes y las partes interesadas. Sin embargo, los modelos de evaluación existentes tienen principalmente fines de acreditación y están diseñados para evaluar la eficacia, es decir si los resultados obtenidos están de acuerdo con la misión y los objetivos planteados. Su objetivo no es medir la pertinencia. Esta investigación tiene como objetivo diseñar un modelo de evaluación de la pertinencia de maestrías en ingeniería y aplicarlo a un caso concreto. Se trata de maestrías que ya están en funcionamiento y son dictadas en una universidad en un país en desarrollo. Para diseñar el modelo se define primero el concepto de pertinencia de una maestría en ingeniería haciendo una revisión bibliográfica y consultando a expertos en los temas de pertinencia de la educación superior y formación en postgrado en ingeniería. Se utiliza una definición operativa que facilita luego la identificación de factores e indicadores de evaluación. Se identifica dos tipos de pertinencia: local y global. La pertinencia global está relacionada con la inserción de la maestría en el sistema global de producción de conocimiento. La pertinencia local tiene tres dimensiones: la personal, relacionada con la satisfacción de necesidades de los estudiantes, la institucional, relacionada con las necesidades e intereses de la universidad que acoge a la maestría y la pertinencia social, ligada a la satisfacción de necesidades y demandas de la comunidad local y nacional. El modelo diseñado es aplicado en la maestría en Ingeniería Civil con mención en Ingeniería Vial de la Universidad de Piura, Perú lo que permite obtener conclusiones para su aplicación en otras maestrías. ABSTRACT Graduate engineering education is very important to improve competitiveness and achieve development in countries. It is necessary a strong linkage between university and its socio economic environment, so that programs objectives are consistent with the real needs of the students, university and community. That is to say programs must be relevant. And in developing countries this issue is very important. Evaluation models to measure the degree of adequacy between the programs objectives with the needs of students and stakeholders is needed. However, existing evaluation models have mainly the purpose of accreditation and are designed to evaluate the efficacy. They evaluate if the results are consistent with the mission and objectives. Their goal is not to measure the relevance. This work aimed to design a model for evaluating the relevance of master's degrees in engineering and applied to a specific case. They must be masters already in operation and are taught at a university in a developing country. In order to build the model, first concept of relevance of a master's degree in engineering was defined. Literature was reviewed and we consulted experts on issues of relevance of higher education and graduate engineering education. An operational definition is used to facilitate the identification of factors and evaluation indicators. Local and global: two types of relevance were identified. The global relevance is related to the inclusion of Master in the global system of knowledge production. The local relevance has three dimensions: personal, related to meeting students' needs, institutional, related to the needs and interests of university that houses the Master and social relevance, linked to the satisfaction of needs and demands of local and national community. The designed model is applied to the Master degree in Civil Engineering with a major in Traffic Engineering of Universidad de Piura, Peru which allowed to obtain conclusions for application in other masters.
