Emotions and the Engineering of Adaptiveness in Complex Systems

A major challenge in the engineering of complex and critical systems is the management of change, both in the system and in its operational environment. Due to the growing of complexity in systems, new approaches on autonomy must be able to detect critical changes and avoid their progress towards undesirable states. We are searching for methods to build systems that can tune the adaptability protocols. New mechanisms that use system-wellness requirements to reduce the influence of the outer domain and transfer the control of uncertainly to the inner one. Under the view of cognitive systems, biological emotions suggests a strategy to configure value-based systems to use semantic self-representations of the state. A method inspired by emotion theories to causally connect to the inner domain of the system and its objectives of wellness, focusing on dynamically adapting the system to avoid the progress of critical states. This method shall endow the system with a transversal mechanism to monitor its inner processes, detecting critical states and managing its adaptivity in order to maintain the wellness goals. The paper describes the current vision produced by this work-in-progress.

Creating and modelling personal socio-economic networks in on-line banking

The banking industry is observing how new competitors threaten its millennial business model by targeting unbanked people, offering new financial services to their customer base, and even enabling new channels for existing services and customers. The knowledge on users, their behaviour, and expectations become a key asset in this new context. Well aware of this situation, the Center for Open Middleware, a joint technology center created by Santander Bank and Universidad Politécnica de Madrid, has launched a set of initiatives to allow the experimental analysis and management of socio-economic information. PosdataP2P service is one of them, which seeks to model the economic ties between the holders of university smart cards, leveraging on the social networks the holders are subscribed to. In this paper we describe the design principles guiding the development of the system, its architecture and some implementation details.

Cuadro de mando, plataforma de gestión para el modelo EFQM

La propuesta del trabajo de fin de grado escogida por el autor del proyecto se basa en la continuación del proyecto comenzado durante la asignatura de Prácticum del pasado semestre. El nacimiento del mismo se gestó en una pequeña empresa de consultoría llamada ‘Grupo Develop’ (en la sección ‘Entidad colaboradora y ubicación’ se describe más detalladamente la organización) situada al este de Madrid, una organización con carácter de fundación y dedicada, esencialmente, al sector de la consultoría en el sector de la calidad. Grupo Develop necesitaba aprovechar la utilidad de las nuevas tecnologías para ofrecer un nuevo y mejor servicio para sus clientes mediante un proyecto que fuera dirigido y llevado a cabo por un ingeniero informático. Partiendo de este contexto se vislumbró un proyecto consistente en diseñar, desplegar, programar y mantener una plataforma-sistema informático capaz de ayudar a las organizaciones (en este caso particular la mayoría son organizaciones sin ánimo de lucro) a gestionarse mejor de acuerdo a distintos modelos de calidad como pueden ser el EFQM1 o ISO. Además, la certificación en ambos modelos son cada vez más demandados como garantía de calidad por organismos públicos y privados e incluso por los clientes. Por lo tanto, este programa debe llegar a ser una herramienta que realmente apoye a cada entidad a elaborar un diagnóstico de su gestión y, por supuesto, debe conseguir acercar a estas empresas a los certificados más prestigiosos. Desde el punto de vista de un profesional del sector de la informática, el proyecto se estructura de una forma clara en una arquitectura cliente-servidor clásica donde todas las entidades (de momento 15) han participado de forma activa y paralela al desarrollo del proyecto. Si bien es cierto que esto ha ralentizado notablemente el desarrollo del proyecto y ha requerido una sincronización entre dos proyectos paralelos (uno para el despliegue y otro para el desarrollo).---ABSTRACT---The proposal of my graduation work is a continuation of the project that I already started in the Practicum subject the first part of the academic year. The birth of that project arose in a small consulting firm (Grupo Develop) in the east of Madrid, an organization that at the same time is incorporated as a Foundation. This organization works with different NGO´s and their work covers the Quality Consulting Sector. Grupo Develop needed to use new technologies to give a new and best service to our customers through a project managed by a person trained in the computer science area. Starting from this context, Grupo Develop saw a new opportunity to create a project to design, deploy and maintain a platform-system that can help our customers (in this case the organizations are often organizations from the Third Sector) to get a best management in some Norms or Models like ISO or EFQM. Also in some cases the Certifications of any of these models are increasingly demanded as quality assurance by public entities, privates and even by clients. Therefore, this program should be a tool that helps to any organization to make a diagnosis of their management and, of course, should close to these companies to the most prestigious Certificates. From a point of view of a computer science student, the software project has a defined structure in a classic client-server model where all the organizations (15) have actively participated in parallel mode to the development of the project. It is true that the involvement of the organizations has slowed the development of the project so I had to create two projects (one for the different organizations and the other one to develop the major improvements).

Desarrollo de frameworks con .NET

La expansión experimentada por la informática, las nuevas tecnologías e internet en los últimos años, no solo viene dada por la evolución del hardware subyacente, sino por la evolución del desarrollo de software y del crecimiento del número de desarrolladores. Este incremento ha hecho evolucionar el software de unos sistemas de gestión basados en ficheros, prácticamente sin interfaz gráfico y de unos pocos miles de líneas a grandes sistemas distribuidos multiplataforma. El desarrollo de estos grandes sistemas, requiere gran cantidad de personas involucradas en el desarrollo, y que las herramientas de desarrollo hayan crecido también para facilitar su análisis, diseño, codificación, pruebas, implantación y mantenimiento. La base de estas herramientas software las proveen las propias plataformas de desarrollo, pero la experiencia de los desarrolladores puede aportar un sinfín de utilidades y de técnicas que agilicen los desarrollos y cumplan los requisitos del software en base a la reutilización de soluciones lo suficientemente probadas y optimizadas. Dichas herramientas se agrupan ordenadamente, creando así frameworks personalizados, con herramientas de todo tipo, clases, controles, interfaces, patrones de diseño, de tal manera que se dan soluciones personalizadas a un amplio número de problemas para emplearlas cuantas veces se quiera, bien marcando directrices de desarrollo mediante el uso de patrones, bien con la encapsulación de complejidades de tal modo que los desarrolladores ya dispongan de componentes que asuman cierta lógica o cierta complejidad aliviando así la fase de construcción. En este trabajo se abordan temas sobre las tecnologías base y plataformas de desarrollo para poder acometer la creación de un framework personalizado, necesidades a evaluar antes de acometerlo, y técnicas a emplear para la consecución del mismo, orientadas a la documentación, mantenimiento y extensión del framework. La exposición teórica consiste en mostrar y evaluar los requisitos para crear un framework, requisitos de la plataforma de desarrollo, y explicar cómo funcionan las grandes plataformas de desarrollo actuales, que elementos los componen y su funcionamiento, así como marcar ciertas pautas de estructuración y nomenclatura que el desarrollo de un framework debe contemplar para su mantenimiento y extensión. En la parte metodológica se ha usado un subconjunto de Métrica V3, ya que para el desarrollo de controles no aplica dicha metodología en su totalidad, pero contempla el catálogo de requisitos, los casos de uso, diagramas de clase, diagramas de secuencia, etc… Aparte de los conceptos teóricos, se presenta un caso práctico con fines didácticos de cómo parametrizar y configurar el desarrollo bajo la plataforma .NET. Dicho caso práctico consiste en la extensión de un control de usuario genérico de la plataforma .NET, de tal modo que se aplican conceptos más allá del hecho de crear funciones como las funcionalidades que puede brindar un API. Conceptos sobre como extender y modificar controles ya existentes, que interactúan por medio de eventos con otros controles, con vistas a que ese nuevo control forme parte de una biblioteca de controles de usuario personalizados ampliamente divulgada. Los controles de usuario son algo que no solo tienen una parte funcional, sino que también tienen una parte visual, y definiciones funcionales distintas de las típicas del software de gestión, puesto que han de controlar eventos, visualizaciones mientras se dan estos eventos y requisitos no funcionales de optimización de rendimiento, etc… Para el caso práctico se toma como herramienta la plataforma de desarrollo .Net Framework, en todas sus versiones, ya que el control a extender es el control ListView y hacerlo editable. Este control está presente en todas las versiones de .NET framework y con un alto grado de reutilización. Esta extensión muestra además como se puede migrar fácilmente este tipo de extensiones sobre todos los frameworks. Los entornos de desarrollo usados son varias versiones de Visual Studio para el mostrar dicha compatibilidad, aunque el desarrollo que acompaña este documento esté realizado sobre Visual Studio 2013. ABSTRACT The expansion in computer science, new technologies and the Internet in recent years, not only is given by the evolution of the underlying hardware, but for the evolution of software development and the growing number of developers. This increase has evolved software from management systems based on files almost without graphical interface and a few thousand of code lines, to large multiplatform distributed systems. The development of these large systems, require lots of people involved in development, and development tools have also grown to facilitate analysis, design, coding, testing, deployment and maintenance. The basis of these software tools are providing by their own development platforms, but the experience of the developers can bring a lot of utilities and techniques to speed up developments and meet the requirements of software reuse based on sufficiently proven solutions and optimized. These tools are grouped neatly, creating in this way custom frameworks, with tools of all types, classes, controls, interfaces, design patterns,… in such a way that they provide customized solutions to a wide range of problems to use them many times as you want to occur, either by dialing development guidelines by using patterns or along with the encapsulation of complexities, so that developers already have components that take some logic or some complexity relieving the construction phase. This paper cover matters based on technologies and development platforms to undertake the creation of a custom framework, needs to evaluate before rush it and techniques to use in order to achieve it, a part from techniques oriented to documentation, maintenance and framework extension. The theoretical explanation consists in to demonstrate and to evaluate the requirements for creating a framework, development platform requirements, and explain how large current development platforms work, which elements compose them and their operation work, as well as mark certain patterns of structure and nomenclature that the development of a framework should include for its maintenance and extension. In the methodological part, a subset of Métrica V3 has been used, because of, for the development of custom controls this methodology does not apply in its entirety, but provides a catalogue of requirements, use cases, class diagrams, sequence diagrams, etc ... Apart from the theoretical concepts, a study case for teaching purposes about how to parameterize and configure the development under the .NET platform is presented. This study case involves the extension of a generic user control of the .NET platform, so that concepts apply beyond the fact of creating functions as the functionalities that can provide an API. Concepts on how to extend and modify existing controls that interact through events with other controls, overlooking that new control as a part of a custom user controls library widely publicized. User controls are something that not only have a functional part, but also have a visual part, and various functional definitions of typical management software, since that they have to control events, visualizations while these events are given and not functional of performance optimization requirements, etc ... For the study case the development platform .Net Framework is taken as tool, in all its versions, considering that control to extend is the ListView control and make it editable. This control is present in all versions of .NET framework and with a high degree of reuse. This extension also shows how you can easily migrate these extensions on all frameworks. The used development environments are several versions of Visual Studio to show that compatibility, although the development that accompanies this document is done on Visual Studio 2013.

GESTÃO DO CONHECIMENTO: UM ESTUDO SOBRE A RELAÇÃO ENTRE A LIDERANÇA TRANSFORMACIONAL, A CONVERSÃO DO CONHECIMENTO E A EFICÁCIA ORGANIZACIONAL

Este estudo teve como objetivo principal analisar a relação entre a Liderança Transformacional, a Conversão do Conhecimento e a Eficácia Organizacional. Foram considerados como pressupostos teóricos conceitos consolidados sobre os temas desta relação, além de recentes pesquisas já realizadas em outros países e contextos organizacionais. Com base nisto identificou-se potencial estudo de um modelo que relacionasse estes três conceitos. Para tal considera-se que as organizações que buscam atingir Vantagem Competitiva e incorporam a Knowledge-Based View possam conquistar diferenciação frente a seus concorrentes. Nesse contexto o conhecimento ganha maior destaque e papel protagonista nestas organizações. Dessa forma criar conhecimento através de seus colaboradores, passa a ser um dos desafios dessas organizações ao passo que sugere melhoria de seus indicadores Econômicos, Sociais, Sistêmicos e Políticos, o que se define por Eficácia Organizacional. Portanto os modos de conversão do conhecimento nas organizações, demonstram relevância, uma vez que se cria e se converte conhecimentos através da interação entre o conhecimento existente de seus colaboradores. Essa conversão do conhecimento ou modelo SECI possui quatro modos que são a Socialização, Externalização, Combinação e Internalização. Nessa perspectiva a liderança nas organizações apresenta-se como um elemento capaz de influenciar seus colaboradores, propiciando maior dinâmica ao modelo SECI de conversão do conhecimento. Se identifica então na liderança do tipo Transformacional, características que possam influenciar colaboradores e entende-se que esta relação entre a Liderança Transformacional e a Conversão do Conhecimento possa ter influência positiva nos indicadores da Eficácia Organizacional. Dessa forma esta pesquisa buscou analisar um modelo que explorasse essa relação entre a liderança do tipo Transformacional, a Conversão do Conhecimento (SECI) e a Eficácia Organizacional. Esta pesquisa teve o caráter quantitativo com coleta de dados através do método survey, obtendo um total de 230 respondentes válidos de diferentes organizações. O instrumento de coleta de dados foi composto por afirmativas relativas ao modelo de relação pesquisado com um total de 44 itens. O perfil de respondentes concentrou-se entre 30 e 39 anos de idade, com a predominância de organizações privadas e de departamentos de TI/Telecom, Docência e Recursos Humanos respectivamente. O tratamento dos dados foi através da Análise Fatorial Exploratória e Modelagem de Equações Estruturais via Partial Least Square Path Modeling (PLS-PM). Como resultado da análise desta pesquisa, as hipóteses puderam ser confirmadas, concluindo que a Liderança Transformacional apresenta influência positiva nos modos de Conversão do Conhecimento e que; a Conversão do Conhecimento influencia positivamente na Eficácia Organizacional. Ainda, concluiu-se que a percepção entre os respondentes não apresenta resultado diferente sobre o modelo desta pesquisa entre quem possui ou não função de liderança.

Data normalization and integration in robotic systems using web services technologies

The robotics is one of the most active areas. We also need to join a large number of disciplines to create robots. With these premises, one problem is the management of information from multiple heterogeneous sources. Each component, hardware or software, produces data with different nature: temporal frequencies, processing needs, size, type, etc. Nowadays, technologies and software engineering paradigms such as service-oriented architectures are applied to solve this problem in other areas. This paper proposes the use of these technologies to implement a robotic control system based on services. This type of system will allow integration and collaborative work of different elements that make up a robotic system.

Web-based OERs in Computer Networks

Learning and teaching processes are continually changing. Therefore, design of learning technologies has gained interest in educators and educational institutions from secondary school to higher education. This paper describes the successfully use in education of social learning technologies and virtual laboratories designed by the authors, as well as videos developed by the students. These tools, combined with other open educational resources based on a blended-learning methodology, have been employed to teach the subject of Computer Networks. We have verified not only that the application of OERs into the learning process leads to a significantly improvement of the assessments, but also that the combination of several OERs enhances their effectiveness. These results are supported by, firstly, a study of both students’ opinion and students’ behaviour over five academic years, and, secondly, a correlation analysis between the use of OERs and the grades obtained by students.

Computer Networks Virtualization with GNS3: Evaluating a solution to optimize resources and achieve a distance learning

Designing educational resources allow students to modify their learning process. In particular, on-line and downloadable educational resources have been successfully used in engineering education the last years [1]. Usually, these resources are free and accessible from web. In addition, they are designed and developed by lecturers and used by their students. But, they are rarely developed by students in order to be used by other students. In this work-in-progress, lecturers and students are working together to implement educational resources, which can be used by students to improve the learning process of computer networks subject in engineering studies. In particular, network topologies to model LAN (Local Area Network) and MAN (Metropolitan Area Network) are virtualized in order to simulate the behavior of the links and nodes when they are interconnected with different physical and logical design.

Experiences Using an Open Source Sofware Library to Teach Computer Vision Subjects

Machine vision is an important subject in computer science and engineering degrees. For laboratory experimentation, it is desirable to have a complete and easy-to-use tool. In this work we present a Java library, oriented to teaching computer vision. We have designed and built the library from the scratch with enfasis on readability and understanding rather than on efficiency. However, the library can also be used for research purposes. JavaVis is an open source Java library, oriented to the teaching of Computer Vision. It consists of a framework with several features that meet its demands. It has been designed to be easy to use: the user does not have to deal with internal structures or graphical interface, and should the student need to add a new algorithm it can be done simply enough. Once we sketch the library, we focus on the experience the student gets using this library in several computer vision courses. Our main goal is to find out whether the students understand what they are doing, that is, find out how much the library helps the student in grasping the basic concepts of computer vision. In the last four years we have conducted surveys to assess how much the students have improved their skills by using this library.

Granular computing as a basis of human–data interaction: a cognitive cities use case

The article proposes granular computing as a theoretical, formal and methodological basis for the newly emerging research field of human–data interaction (HDI). We argue that the ability to represent and reason with information granules is a prerequisite for data legibility. As such, it allows for extending the research agenda of HDI to encompass the topic of collective intelligence amplification, which is seen as an opportunity of today’s increasingly pervasive computing environments. As an example of collective intelligence amplification in HDI, we introduce a collaborative urban planning use case in a cognitive city environment and show how an iterative process of user input and human-oriented automated data processing can support collective decision making. As a basis for automated human-oriented data processing, we use the spatial granular calculus of granular geometry.
