A characterization of conserved quantities in non-equilibrium thermodynamics

The well-known Noether theorem in Lagrangian and Hamiltonian mechanics associates symmetries in the evolution equations of a mechanical system with conserved quantities. In this work, we extend this classical idea to problems of non-equilibrium thermodynamics formulated within the GENERIC (General Equations for Non-Equilibrium Reversible-Irreversible Coupling) framework. The geometric meaning of symmetry is reviewed in this formal setting and then utilized to identify possible conserved quantities and the conditions that guarantee their strict conservation. Examples are provided that demonstrate the validity of the proposed definition in the context of finite and infinite dimensional thermoelastic problems.

The city as a learning gamified platform

The area of mobile city guides has grown really fast in the last years based on new mobile capabilities. This growth has been fostered by the evolution of ubiquitous systems and the great penetration of smartphones in the society. In this paper we propose a generic model to support a new way of visiting the city: instead of as a place for tourism, we see it as a place for learning in which located educational resources are available for end users. The model has been conceived as a way to encourage them to create their own educational tours, in which Learning Points Of Interest are set up to be discovered. Two main use cases are supported by the model: formal (conducted by a teacher) and informal (no educator is related to the learning experience) outdoor mobile learning. Details about the impact of the conjunction of tourism, learning and gamification dimensions in the model design, as well as about the model itself are provided. Finally, a mobile application prototype developed in the context of the FI-CONTENT European project is presented as a proof of concept of the model.

Teaching automatic control in non-specialist engineering schools

Automatic Control Teaching in the new degree syllabus has reduced both, its contents and its implementation course, with regard to traditional engineering careers. On the other hand, where the qualification is not considered as automatic control specialist, it is required an adapted methodology to provide the minimum contents that the student needs to assimilate, even in the case that students do not perceive these contents as the most important in their future career. In this paper we present the contents of a small automatic course taught Naval Architecture and Marine Engineering Degrees at the School of Naval Engineering of the Polytechnic University of Madrid. We have included the contents covered using the proposed methodology which is based on practical work after lectures. Firstly, the students performed exercises by hand. Secondly, they solve the exercises using informatics support tools, and finally, they validate their previous results and their knowledge in the laboratory platforms.

Blended learning in the design of collective protections in building works

The design of collective protections of construction works is a topic that is integrated within one of the MBTI subjects. This paper presents an experience for teaching the design of collective protection in building works. Teaching has been done in a bended way. This subject is taught as part of the content of a wider subject included in the Master "Building Technological Innovation" (MBTI) of the Universidad Politécnica de Madrid (UPM). This Master's degree is a postgraduate of research nature. Graduating in MBTI implies that students are in a position to begin their PhD thesis. At this stage, often students are not able to follow the rigour established by the schedule of classes. For this reason it is interesting that part of the teaching is developed in a non-classroom based way.

On-line learning of a fuzzy controller for a precise vehicle cruise control system

Usually, vehicle applications require the use of artificial intelligent techniques to implement control methods, due to noise provided by sensors or the impossibility of full knowledge about dynamics of the vehicle (engine state, wheel pressure or occupiers weight). This work presents a method to on-line evolve a fuzzy controller for commanding vehicles? pedals at low speeds; in this scenario, the slightest alteration in the vehicle or road conditions can vary controller?s behavior in a non predictable way. The proposal adapts singletons positions in real time, and trapezoids used to codify the input variables are modified according with historical data. Experimentation in both simulated and real vehicles are provided to show how fast and precise the method is, even compared with a human driver or using different vehicles.

A machine learning approach to identify clinical trials involving nanodrugs and nanodevices from ClinicalTrials.gov

BACKGROUND: Clinical Trials (CTs) are essential for bridging the gap between experimental research on new drugs and their clinical application. Just like CTs for traditional drugs and biologics have helped accelerate the translation of biomedical findings into medical practice, CTs for nanodrugs and nanodevices could advance novel nanomaterials as agents for diagnosis and therapy. Although there is publicly available information about nanomedicine-related CTs, the online archiving of this information is carried out without adhering to criteria that discriminate between studies involving nanomaterials or nanotechnology-based processes (nano), and CTs that do not involve nanotechnology (non-nano). Finding out whether nanodrugs and nanodevices were involved in a study from CT summaries alone is a challenging task. At the time of writing, CTs archived in the well-known online registry ClinicalTrials.gov are not easily told apart as to whether they are nano or non-nano CTs-even when performed by domain experts, due to the lack of both a common definition for nanotechnology and of standards for reporting nanomedical experiments and results. METHODS: We propose a supervised learning approach for classifying CT summaries from ClinicalTrials.gov according to whether they fall into the nano or the non-nano categories. Our method involves several stages: i) extraction and manual annotation of CTs as nano vs. non-nano, ii) pre-processing and automatic classification, and iii) performance evaluation using several state-of-the-art classifiers under different transformations of the original dataset. RESULTS AND CONCLUSIONS: The performance of the best automated classifier closely matches that of experts (AUC over 0.95), suggesting that it is feasible to automatically detect the presence of nanotechnology products in CT summaries with a high degree of accuracy. This can significantly speed up the process of finding whether reports on ClinicalTrials.gov might be relevant to a particular nanoparticle or nanodevice, which is essential to discover any precedents for nanotoxicity events or advantages for targeted drug therapy.

iCarer Project: Intelligent Care Guidance and Learning Services Platform for Informal Carers of the Elderly

The increasing ageing population is demanding new care approaches to maintain the quality of life of elderly people. Informal carers are becoming crucial agents in the care and support of elderly people, which can lead to those carers suffering from additional stress due to competing priorities with employment or due to lack of knowledge about elderly people?s care needs. Thus, support and stress relief in carers should be a key issue in the home-care process of these older adults. Considering this context, this work presents the iCarer project aimed at developing a personalized and adaptive platform to offer informal carers support by means of monitoring their activities of daily care and psychological state, as well as providing an orientation to help them improve the care provided. Additionally, iCarer will provide e-Learning services and an informal carers learning network. As a result, carers will be able to expand their knowledge, supported by the experience provided by expert counsellors and fellow carers. Additionally, the coordination between formal and informal carers will be improved, offering the informal carers flexibility to organize and combine their assistance and social activities.

Método para el análisis independiente de problemas

habilidades de comprensión y resolución de problemas. Tanto es así que se puede afirmar con rotundidad que no existe el método perfecto para cada una de las etapas de desarrollo y tampoco existe el modelo de ciclo de vida perfecto: cada nuevo problema que se plantea es diferente a los anteriores en algún aspecto y esto hace que técnicas que funcionaron en proyectos anteriores fracasen en los proyectos nuevos. Por ello actualmente se realiza un planteamiento integrador que pretende utilizar en cada caso las técnicas, métodos y herramientas más acordes con las características del problema planteado al ingeniero. Bajo este punto de vista se plantean nuevos problemas. En primer lugar está la selección de enfoques de desarrollo. Si no existe el mejor enfoque, ¿cómo se hace para elegir el más adecuado de entre el conjunto de los existentes? Un segundo problema estriba en la relación entre las etapas de análisis y diseño. En este sentido existen dos grandes riesgos. Por un lado, se puede hacer un análisis del problema demasiado superficial, con lo que se produce una excesiva distancia entre el análisis y el diseño que muchas veces imposibilita el paso de uno a otro. Por otro lado, se puede optar por un análisis en términos del diseño que provoca que no cumpla su objetivo de centrarse en el problema, sino que se convierte en una primera versión de la solución, lo que se conoce como diseño preliminar. Como consecuencia de lo anterior surge el dilema del análisis, que puede plantearse como sigue: para cada problema planteado hay que elegir las técnicas más adecuadas, lo que requiere que se conozcan las características del problema. Para ello, a su vez, se debe analizar el problema, eligiendo una técnica antes de conocerlo. Si la técnica utiliza términos de diseño entonces se ha precondicionado el paradigma de solución y es posible que no sea el más adecuado para resolver el problema. En último lugar están las barreras pragmáticas que frenan la expansión del uso de métodos con base formal, dificultando su aplicación en la práctica cotidiana. Teniendo en cuenta todos los problemas planteados, se requieren métodos de análisis del problema que cumplan una serie de objetivos, el primero de los cuales es la necesidad de una base formal, con el fin de evitar la ambigüedad y permitir verificar la corrección de los modelos generados. Un segundo objetivo es la independencia de diseño: se deben utilizar términos que no tengan reflejo directo en el diseño, para que permitan centrarse en las características del problema. Además los métodos deben permitir analizar problemas de cualquier tipo: algorítmicos, de soporte a la decisión o basados en el conocimiento, entre otros. En siguiente lugar están los objetivos relacionados con aspectos pragmáticos. Por un lado deben incorporar una notación textual formal pero no matemática, de forma que se facilite su validación y comprensión por personas sin conocimientos matemáticos profundos pero al mismo tiempo sea lo suficientemente rigurosa para facilitar su verificación. Por otro lado, se requiere una notación gráfica complementaria para representar los modelos, de forma que puedan ser comprendidos y validados cómodamente por parte de los clientes y usuarios. Esta tesis doctoral presenta SETCM, un método de análisis que cumple estos objetivos. Para ello se han definido todos los elementos que forman los modelos de análisis usando una terminología independiente de paradigmas de diseño y se han formalizado dichas definiciones usando los elementos fundamentales de la teoría de conjuntos: elementos, conjuntos y relaciones entre conjuntos. Por otro lado se ha definido un lenguaje formal para representar los elementos de los modelos de análisis – evitando en lo posible el uso de notaciones matemáticas – complementado con una notación gráfica que permite representar de forma visual las partes más relevantes de los modelos. El método propuesto ha sido sometido a una intensa fase de experimentación, durante la que fue aplicado a 13 casos de estudio, todos ellos proyectos reales que han concluido en productos transferidos a entidades públicas o privadas. Durante la experimentación se ha evaluado la adecuación de SETCM para el análisis de problemas de distinto tamaño y en sistemas cuyo diseño final usaba paradigmas diferentes e incluso paradigmas mixtos. También se ha evaluado su uso por analistas con distinto nivel de experiencia – noveles, intermedios o expertos – analizando en todos los casos la curva de aprendizaje, con el fin de averiguar si es fácil de aprender su uso, independientemente de si se conoce o no alguna otra técnica de análisis. Por otro lado se ha estudiado la capacidad de ampliación de modelos generados con SETCM, para comprobar si permite abordar proyectos realizados en varias fases, en los que el análisis de una fase consista en ampliar el análisis de la fase anterior. En resumidas cuentas, se ha tratado de evaluar la capacidad de integración de SETCM en una organización como la técnica de análisis preferida para el desarrollo de software. Los resultados obtenidos tras esta experimentación han sido muy positivos, habiéndose alcanzado un alto grado de cumplimiento de todos los objetivos planteados al definir el método.---ABSTRACT---Software development is an inherently complex activity, which requires specific abilities of problem comprehension and solving. It is so difficult that it can even be said that there is no perfect method for each of the development stages and that there is no perfect life cycle model: each new problem is different to the precedent ones in some respect and the techniques that worked in other problems can fail in the new ones. Given that situation, the current trend is to integrate different methods, tools and techniques, using the best suited for each situation. This trend, however, raises some new problems. The first one is the selection of development approaches. If there is no a manifestly single best approach, how does one go about choosing an approach from the array of available options? The second problem has to do with the relationship between the analysis and design phases. This relation can lead to two major risks. On one hand, the analysis could be too shallow and far away from the design, making it very difficult to perform the transition between them. On the other hand, the analysis could be expressed using design terminology, thus becoming more a kind of preliminary design than a model of the problem to be solved. In third place there is the analysis dilemma, which can be expressed as follows. The developer has to choose the most adequate techniques for each problem, and to make this decision it is necessary to know the most relevant properties of the problem. This implies that the developer has to analyse the problem, choosing an analysis method before really knowing the problem. If the chosen technique uses design terminology then the solution paradigm has been preconditioned and it is possible that, once the problem is well known, that paradigm wouldn’t be the chosen one. The last problem consists of some pragmatic barriers that limit the applicability of formal based methods, making it difficult to use them in current practice. In order to solve these problems there is a need for analysis methods that fulfil several goals. The first one is the need of a formal base, which prevents ambiguity and allows the verification of the analysis models. The second goal is design-independence: the analysis should use a terminology different from the design, to facilitate a real comprehension of the problem under study. In third place the analysis method should allow the developer to study different kinds of problems: algorithmic, decision-support, knowledge based, etc. Next there are two goals related to pragmatic aspects. Firstly, the methods should have a non mathematical but formal textual notation. This notation will allow people without deep mathematical knowledge to understand and validate the resulting models, without losing the needed rigour for verification. Secondly, the methods should have a complementary graphical notation to make more natural the understanding and validation of the relevant parts of the analysis. This Thesis proposes such a method, called SETCM. The elements conforming the analysis models have been defined using a terminology that is independent from design paradigms. Those terms have been then formalised using the main concepts of the set theory: elements, sets and correspondences between sets. In addition, a formal language has been created, which avoids the use of mathematical notations. Finally, a graphical notation has been defined, which can visually represent the most relevant elements of the models. The proposed method has been thoroughly tested during the experimentation phase. It has been used to perform the analysis of 13 actual projects, all of them resulting in transferred products. This experimentation allowed evaluating the adequacy of SETCM for the analysis of problems of varying size, whose final design used different paradigms and even mixed ones. The use of the method by people with different levels of expertise was also evaluated, along with the corresponding learning curve, in order to assess if the method is easy to learn, independently of previous knowledge on other analysis techniques. In addition, the expandability of the analysis models was evaluated, assessing if the technique was adequate for projects organised in incremental steps, in which the analysis of one step grows from the precedent models. The final goal was to assess if SETCM can be used inside an organisation as the preferred analysis method for software development. The obtained results have been very positive, as SETCM has obtained a high degree of fulfilment of the goals stated for the method.

Improving engineering students' communication competence: designing innovative learning strategies

This research presents an innovative and formal educational initiative that is aimed at enhancing the development of engineering students’ specific competencies when studying Engineering Project Management subject. The framework of the experience combines theoretical concepts, the development of a real-case project carried out by multidisciplinary groups of three different universities, the use of software web 2.0 tools, and group and individual assignments of students that play different roles (project managers and team members). Under this scenario, this paper focuses on monitoring the communication competence in the ever growing Project Management virtual environment. Factors such as corporal language, technical means, stage, and management specific vocabulary among others have been considered in order to assess the students’ performance on this issue. As a main contribution, the paper introduces an ad-hoc rubric that, based on previous investigations, has been adapted and tested to this specific context. Additionally, the research conducted has provided some interesting findings that suggest further actions to improve and better define future rubrics, oriented to communication or even other competencies. As specific Project Management subject concerns, it has been detected that students playing the role of Project Managers strengthen their competencies more than those ones that play the role of Team Members. It has also been detected that students have more difficulty assimilating concepts related to risk and quality management. However those concepts related with areas of knowledge like scope, time or cost have been better assimilated by the students.

Facilitating the creation of interactive multi-device Learning Objects using an online authoring tool

Learning Objects facilitate reuse leading to cost and time savings as well as to the enhancement of the quality of educational resources. However, teachers find it difficult to create or to find high quality Learning Objects, and the ones they find need to be customized. Teachers can overcome this problem using suitable authoring systems that enable them to create high quality Learning Objects with little effort. This paper presents an open source online e-Learning authoring tool called ViSH Editor together with four novel interactive Learning Objects that can be created with it: Flashcards, Virtual Tours, Enriched Videos and Interactive Presentations. All these Learning Objects are created as web applications, which can be accessed via mobile devices. Besides, they can be exported to SCORM including their metadata in IEEE LOM format. All of them are described in the paper including an example of each. This approach for creating Learning Objects was validated through two evaluations: a survey among authors and a formal quality evaluation of 209 Learning Objects created with the tool. The results show that ViSH Editor facilitates educators the creation of high quality Learning Objects.

Some reflections on the impact of globalization in the teaching and learning of English in socalled “expanding circle” countries

This article deals with the ongoing debate on the complex role of English as an International Language, be it understood as a homogeneous entity (one language with an international role [EIL]) or a heterogeneous one (different varieties (WE or ELF) grouped under one label, «English») as well as on the implications of this «globalising» status for its teaching in non-native settings. Given the complexity of this phenomenon, whose study is still in its infancy, we attempt neither to provide definitive answers nor adopt a prescriptive attitude, but simply contribute to the discussion and clarification of this, to some extent, emergent, controversial situation.

The curricular value of mathematics in non-mathematics degree

Higher education should provide the acquisition of skills and abilities that allow the student to play a full and active role in society. The educational experience should offer a series of conceptual, procedural and attitudinal contents that encourage “learning to know, learning to do, learning to be and learning to live together”. It is important to consider the curricular value of mathematics in the education of university undergraduates who do not intend to study mathematics but for whom the discipline will serve as an instrumental. This work discusses factors that form part of the debate on the curricular value of mathematics in non-mathematics degrees.

Academic Achievement in Early Adolescence: The Influence of Cognitive and Non-Cognitive Variables

The present study examined the predictive effects of intellectual ability, self-concept, goal orientations, learning strategies, popularity and parent involvement on academic achievement. Hierarchical regression analysis and path analysis were performed among a sample of 1398 high school students (mean age = 12.5; SD =.67) from eight education centers from the province of Alicante (Spain). Cognitive and non-cognitive variables were measured using validated questionnaires, whereas academic achievement was assessed using end-of-term grades obtained by students in nine subjects. The results revealed significant predictive effects of all of the variables. The model proposed had a satisfactory fit, and all of the hypothesized relationships were significant. These findings support the importance of including non-cognitive variables along with cognitive variables when predicting a model of academic achievement.

An Architecture by means of Anthropology. Beyond learning the tools of social science

Los arquitectos y urbanistas tienen una larga tradición en el aprendizaje de las herramientas de las ciencias sociales, especialmente las que les permiten analizar y describir mejor los entornos y las personas para las que trabajan. Esto ha llevado a los arquitectos a desarrollar mejores herramientas de observación y descripción del ámbito social y no sólo el material. Sin embargo, la mayoría de las veces este acercamiento interdisciplinar ha identificado las ciencias sociales, especialmente la antropología, con la etnografía. Este artículo parte de la crítica a esta identificación hecha por el antropólogo Tim Ingold y se centra en lo que él propone como el método central de la antropología, la observación participante. Para después revisar varias propuestas actuales de científicos sociales que tratan de desarrollar una disciplina no representacional y orientada al futuro, un objetivo más cercano al de la arquitectura. El artículo intenta imaginar cómo esta práctica transdisciplinar podría desarrollarse.

BEYOND WORDS: HOW LEARNING TO READ AND MENTAL HEALTH ARE RELATED FOR STRUGGLING READERS

The overarching purpose of this research program was to describe how intervening for academic deficits may be accompanied by changes in mental health. This multi-dimensional, multi-perspective, and iterative research program was developed to report on two distinct but related studies that addressed the same issue: in what ways does the mental health of students change as they transition from being struggling readers to more able readers? To describe the changes, these studies used a number of qualitative research methodologies—focus groups, individual interviews, and ethnographic case studies. Themes that emerged from the focus group and interview data in the first study were used to create a model that guided observations and interview questions in the second study. The first study described what parents, classroom teachers, and two reading instructors of nine previously struggling readers reported as the outcomes of becoming a more proficient reader. Data from this study indicated three broad domains in which change, as perceived by participants, occurred―cognitive/learning, behavioural/social, and psychological/emotional. Within these three domains, six dimensions were identified as having changed as reading improved: (a) academic achievement, (b) attitude, (c) attention, (d) behaviour, (e) mental health, and (f) empowerment. These domains, dimensions, and 15 constituent elements were used to create the model to guide the subsequent study. The purpose of the second study was to validate and refine this model by using an ethnographic case study approach to explore the ways in which the model accounted for the changes in reading and mental health seen in three boys over the months they participated in the intervention. By investigating the relationship between learning to read and mental health, this research aimed to enhance our understanding of how gains in reading may also improve the mental health of struggling readers. The model was found to be robust and a convenient conceptual framework to further our understanding of this relationship. Importantly, gains made in the cognitive/learning domain through an effective reading intervention, offered in a supportive learning environment, were shown to be accompanied by concomitant gains in both the behavioural/social and psychological/emotional domains—all of which enhance student thriving.
