Este Proyecto Fin de Grado (PFG) tiene como objetivo diseñar e implementar un sistema que genere un fichero de texto que contenga la configuración básica de un encaminador. De esta manera se desea mejorar la eficiencia del personal del departamento donde se va a implantar dicho sistema, liberando a los miembros del mismo de un trabajo repetitivo que se hace varias veces al día. Hasta ahora, esta configuración la realiza cada instalador. Para ello, una vez que se ha cargado y probado la configuración en distintos equipos de manera satisfactoria, se generan un conjunto de plantillas que sirven de modelo para las siguientes configuraciones. Aunque el instalador toma estas plantillas como punto de partida, tiene que modificar manualmente todas las variables que dependen de cada configuración particular. Por tanto, aunque no ha de ejecutar todos los comandos paso a paso, sí debe hacer una revisión total de cada plantilla para generar la configuración adecuada y después cargarla en el encaminador. Para cada configuración se consultan un total de entre tres y siete plantillas. Si a esto se añade que en el departamento se configuran encaminadores de la marca Cisco y Teldat, que de cada marca se utilizan distintos modelos y que la empresa ofrece cuatro tipos de servicio, cada uno con sus particularidades, la tarea de configurar un equipo es costosa. El sistema estará constituido por un servidor web que alojará una base de datos y un programa que permite realizar operaciones de consulta sobre la misma, un sitio web sencillo que hará las funciones de interfaz de usuario y una aplicación que permite generar el fichero de texto que contiene la configuración del encaminador en base a una serie de condicionantes. La base de datos desarrollada es una representación de la utilizada en el entorno real que tiene como objetivo realizar simulaciones del funcionamiento que tendrá el sistema. Por su parte, la funcionalidad del sitio web debe ser la de ofrecer al usuario una interfaz sencilla de utilizar y de interpretar, a través de la cual se puedan realizar consultas a la base de datos así como presentar los resultados de dichas consultas de forma ordenada. La aplicación se encargará de validar los datos a partir de los que se va a generar la configuración, determinar qué plantillas se deben consultar en función a aspectos como el servicio a configurar o la marca del encaminador y finalmente generar el fichero de texto resultado. De este modo, el instalador simplemente tendrá que volcar la información de dicho fichero sobre el encaminador. El sistema se ha diseñado de manera que sea lo más flexible a cambios, puesto que la idea de los miembros del departamento es ampliar la funcionalidad de esta herramienta. ABSTRACT. This Final Degree Project is focused on the design and implementation of a system which is able to generate a text file that contains the basic configuration of a router. With this system we want to improve the efficiency of the department members where this system is going to be introduced, releasing them from repetitive work which is done several times per day. Up to now, each installer has to configure the router manually. After checking the configuration of several devices successfully, they create a set of templates which work as models. Although the installers use those templates, they have to modify the variables that depend on the specific features of each kind of configuration. Thus, even though they don´t have to execute the commands step by step, they have to do a review of each used template in order to generate the right configuration. For each configuration, three to seven templates have to be checked. In addition, if the configured routers are both Cisco and Teldat, there are several models per brand and the company offers four types of services to be installed, so the configuration becomes a hard task to do. The system is comprised of a web server in which both the database and the program responsible for doing queries are hosted, a simple web site that will be the graphic user interface, and an application focused on generating the text file which contains the router configuration based on a set of conditions. The developed database is the representation of the real one and its aim is to simulate the way the system will work. The function of the web site is to offer an easy interface whereby you can submit a query or you can see the obtained results as a data table. Furthermore, the application has to validate the data in which the text file with the router configuration is based on. Then, it has to decide which templates it is going to use according to different aspects, such as the brand of the router or the type of service we want to configure. Finally, the application generates a text file with the necessary commands. As a result of this, the user of the system only has to copy the contents of this file to the router. The system has been designed to be flexible to changes because the members of the department want to increase the utility of this tool in the future.

El objetivo del presente trabajo es el estudio, diseño e implementación de una herramienta software, con interfaz gráfica de usuario, que permita aplicar diversas técnicas de análisis de textos de forma simple. Las técnicas de análisis, que serán implementadas en la herramienta, extraerán información de textos escritos en un lenguaje humano, es decir un lenguaje no artificial, y se le presentará al usuario. La herramienta permite la obtención de tres tipos de información: categorías a las que pertenece un texto, dentro de un conjunto de categorías predeterminadas; grupos de textos que son similares entre sí; y la polaridad de opinión expresada en un texto hacia el tema u objeto del que trata, que puede ser neutra, positiva o negativa.---ABSTRACT---The aim of this work is to study, design and implement a software tool, with graphical user interface, which will enable a user to easily apply various text analysis techniques. The techniques implemented in the tool will extract information from texts written in natural language, i.e. a non artificial language, and will present it to the user. The tool will extract three different types of information about a given set of texts: their categories (from a predefined set of categories), groups of similar texts, the polarity of the attitude expressed in the texts towards their topic.

En el año 2014 se publicó, bajo mandato de la Comisión Europea, la Norma Europea EN 301 549, titulada “Requisitos de accesibilidad de productos y servicios TIC aplicables a la contratación pública en Europa”. El objetivo de dicha norma es que los productos o servicios TIC (Tecnologías de la Información y la Comunicación) adquiridos por cualquier administración pública europea puedan ser utilizados por personas con diversas características y capacidades, incluyendo a personas con discapacidad. La norma EN 301 549 es compleja, ya que contiene más de 200 requisitos y recomendaciones, que se aplican o no a un producto o servicio TIC en función de las características de dicho producto o servicio. Por ello se ha planteado, desde el Grupo de Investigación en Tecnología Informática y de las Comunicaciones (CETTICO), el desarrollo de una herramienta de soporte a la evaluación del cumplimiento de la norma. La herramienta permitirá a grupos de trabajo anotar los resultados de la evaluación de accesibilidad de un producto o servicio TIC siguiendo los requisitos de la norma Europea EN 301 549. Este trabajo de Fin de Grado se centra en el diseño y codificación del cliente web de la herramienta. Se parte de los resultados de un TFG y un practicum anteriores. En el TFG realizado por Laura Elorrieta [Elorrieta, 2014], se diseñó la interacción del sistema y se evaluó su grado de usabilidad. En el practicum [Montero, 2015], posterior al TFG de Laura Elorrieta, se eligieron las tecnologías web que se iban a utilizar y se realizó el diseño y la implementación mediante prototipos iterativos de la gestión de proyectos de evaluación. El trabajo que se ha realizado en el TFG ha consistido en el diseño de la interfaz de usuario analizando los cambios a realizar en el diseño, debido a los errores de usabilidad conocidos, y la implementación del prototipo funcional de la herramienta. Junto con la parte servidor del TFG de mi compañero Rubén Ortiz Burgos y la interfaz de usuario de este TFG se ha obtenido una aplicación web para realizar evaluaciones de accesibilidad de productos o servicios TIC siguiendo los requisitos de la norma EN 301 549. El prototipo funcional contiene diez páginas web que recogen las diferentes acciones y tareas que pueden realizar los usuarios en función del rol que desempeñen. EL diseño y la implementación se han llevado a cabo empleando las tecnologías web HTML5, CSS3, JavaScript, jQuery y las librerías de Foundation frontend framework.---ABSTRACT---In 2014, under the European Commission mandate, the European standard EN 301 549 has been published under the title “Accessibility requirements applicable to ICT products and procurement services in Europe”. The goal of this standard is that the products or services ICT (Information Communication Technology) acquires by every European public administration can be used by every person with different characteristics and capacities, including those with disability. The rule EN 301549 is very complex, since it has more than 200 requirements and recommendations that can be or not applied to an ICT product or service based on its characteristics of the given product or service. That’s why a development of a support tool has been proposed to the rating of the compliance of the rule, by the Research Group of Informatics Technology and Communication. This tool will allow working groups to record the results of the compliance of accessibility of a product or service following the requirements of the European Standard EN 301549. This Final Degree Work focuses in the design and the coding of the web customer of this tool. The results of a TFG and previous practicums have been used for this. The TFG performed by Laura Elorrieta [Elorrieta, 2014], the interaction of the system was designed and degree of usability was evaluated. In the practicum [Montero, 2015], after the TFG Laura Elorrieta, web technologies used were chosen and the design and implementation were performed using iterative prototyping project management evaluation. The work done on the TFG was to design the users interface to perform analyzing changes in design due to errors known usability and working prototype implementation of the tool. Together with the server part of the TFG my partner Rubén Ortiz Burgos and the user interface done of this TFG it has obtained a web application for the conduct of evaluations accessibility of products or services ICT following the requirements of the EN 301 549. The functional prototype contains ten web sites that collect the various activities and tasks that users can perform based on the role they perform. The design and implementation have been carried out using the technologies web HTML5, CSS3, Java Script, jQuery and the libraries of Foundation fronted framework.

RegulonDB (version 3.2): transcriptional regulation and operon organization in Escherichia coli K-12
Resumo:
RegulonDB is a database on mechanisms of transcription regulation and operon organization in Escherichia coli K-12. The current version has considerably increased numbers of regulatory elements such as promoters, binding sites and terminators. The complete repertoire of known and predicted DNA-binding transcriptional regulators can be considered to be included in this version. The database now distinguishes different allosteric conformations of regulatory proteins indicating the one active in binding and regulating the different promoters. A new set of operon predictions has been incorporated. The relational design has been modified accordingly. Furthermore, a major improvement is a graphic display enabling browsing of the database with a Java-based graphic user interface with three zoom-levels connected to properties of each chromosomal element. The purpose of these modifications is to make RegulonDB a useful tool and control set for transcriptome experiments. RegulonDB can be accessed on the web at the URL: http://www.cifn.unam.mx/Computational_Biology/regulondb/

Interfaces designed according to ecological interface design (EID) display higher-order relations and properties of a work domain so that adaptive operator problem solving can be better supported under unanticipated system conditions. Previous empirical studies of EID have assumed that the raw data required to derive and communicate higher-order information would be available and reliable. The present research examines the relative advantages of an EID interface over a conventional piping-and-instrumentation diagram (PID) when instrumentation is maximally or only minimally adequate. Results show an interaction between interface and the adequacy of the instrumentation. Failure diagnosis performance with the EID interface with maximally adequate instrumentation is best overall. Performance with the EID interface drops more drastically from maximally to minimally adequate instrumentation than does performance with the PID interface, to the point where the EID interface with minimally adequate instrumentation supports nonsignificantly worse performance than does the equivalent PID interface. Actual or potential applications of this research include design of instrumentation and displays for complex industrial processes.

The Internet of Things (IoT) consists of a worldwide “network of networks,” composed by billions of interconnected heterogeneous devices denoted as things or “Smart Objects” (SOs). Significant research efforts have been dedicated to port the experience gained in the design of the Internet to the IoT, with the goal of maximizing interoperability, using the Internet Protocol (IP) and designing specific protocols like the Constrained Application Protocol (CoAP), which have been widely accepted as drivers for the effective evolution of the IoT. This first wave of standardization can be considered successfully concluded and we can assume that communication with and between SOs is no longer an issue. At this time, to favor the widespread adoption of the IoT, it is crucial to provide mechanisms that facilitate IoT data management and the development of services enabling a real interaction with things. Several reference IoT scenarios have real-time or predictable latency requirements, dealing with billions of device collecting and sending an enormous quantity of data. These features create a new need for architectures specifically designed to handle this scenario, hear denoted as “Big Stream”. In this thesis a new Big Stream Listener-based Graph architecture is proposed. Another important step, is to build more applications around the Web model, bringing about the Web of Things (WoT). As several IoT testbeds have been focused on evaluating lower-layer communication aspects, this thesis proposes a new WoT Testbed aiming at allowing developers to work with a high level of abstraction, without worrying about low-level details. Finally, an innovative SOs-driven User Interface (UI) generation paradigm for mobile applications in heterogeneous IoT networks is proposed, to simplify interactions between users and things.

When constructing and using environmental models, it is typical that many of the inputs to the models will not be known perfectly. In some cases, it will be possible to make observations, or occasionally physics-based uncertainty propagation, to ascertain the uncertainty on these inputs. However, such observations are often either not available or even possible, and another approach to characterising the uncertainty on the inputs must be sought. Even when observations are available, if the analysis is being carried out within a Bayesian framework then prior distributions will have to be specified. One option for gathering or at least estimating this information is to employ expert elicitation. Expert elicitation is well studied within statistics and psychology and involves the assessment of the beliefs of a group of experts about an uncertain quantity, (for example an input / parameter within a model), typically in terms of obtaining a probability distribution. One of the challenges in expert elicitation is to minimise the biases that might enter into the judgements made by the individual experts, and then to come to a consensus decision within the group of experts. Effort is made in the elicitation exercise to prevent biases clouding the judgements through well-devised questioning schemes. It is also important that, when reaching a consensus, the experts are exposed to the knowledge of the others in the group. Within the FP7 UncertWeb project (http://www.uncertweb.org/), there is a requirement to build a Webbased tool for expert elicitation. In this paper, we discuss some of the issues of building a Web-based elicitation system - both the technological aspects and the statistical and scientific issues. In particular, we demonstrate two tools: a Web-based system for the elicitation of continuous random variables and a system designed to elicit uncertainty about categorical random variables in the setting of landcover classification uncertainty. The first of these examples is a generic tool developed to elicit uncertainty about univariate continuous random variables. It is designed to be used within an application context and extends the existing SHELF method, adding a web interface and access to metadata. The tool is developed so that it can be readily integrated with environmental models exposed as web services. The second example was developed for the TREES-3 initiative which monitors tropical landcover change through ground-truthing at confluence points. It allows experts to validate the accuracy of automated landcover classifications using site-specific imagery and local knowledge. Experts may provide uncertainty information at various levels: from a general rating of their confidence in a site validation to a numerical ranking of the possible landcover types within a segment. A key challenge in the web based setting is the design of the user interface and the method of interacting between the problem owner and the problem experts. We show the workflow of the elicitation tool, and show how we can represent the final elicited distributions and confusion matrices using UncertML, ready for integration into uncertainty enabled workflows.We also show how the metadata associated with the elicitation exercise is captured and can be referenced from the elicited result, providing crucial lineage information and thus traceability in the decision making process.

Mobile technology has been one of the major growth areas in computing over recent years (Urbaczewski, Valacich, & Jessup, 2003). Mobile devices are becoming increasingly diverse and are continuing to shrink in size and weight. Although this increases the portability of such devices, their usability tends to suffer. Fuelled almost entirely by lack of usability, users report high levels of frustration regarding interaction with mobile technologies (Venkatesh, Ramesh, & Massey, 2003). This will only worsen if interaction design for mobile technologies does not continue to receive increasing research attention. For the commercial benefit of mobility and mobile commerce (m-commerce) to be fully realized, users’ interaction experiences with mobile technology cannot be negative. To ensure this, it is imperative that we design the right types of mobile interaction (m-interaction); an important prerequisite for this is ensuring that users’ experience meets both their sensory and functional needs (Venkatesh, Ramesh, & Massey, 2003). Given the resource disparity between mobile and desktop technologies, successful electronic commerce (e-commerce) interface design and evaluation does not necessarily equate to successful m-commerce design and evaluation. It is, therefore, imperative that the specific needs of m-commerce are addressed–both in terms of design and evaluation. This chapter begins by exploring the complexities of designing interaction for mobile technology, highlighting the effect of context on the use of such technology. It then goes on to discuss how interaction design for mobile devices might evolve, introducing alternative interaction modalities that are likely to affect that future evolution. It is impossible, within a single chapter, to consider each and every potential mechanism for interacting with mobile technologies; to provide a forward-looking flavor of what might be possible, this chapter focuses on some more novel methods of interaction and does not, therefore, look at the typical keyboard and visual display-based interaction which, in essence, stem from the desktop interaction design paradigm. Finally, this chapter touches on issues associated with effective evaluation of m-interaction and mobile application designs. By highlighting some of the issues and possibilities for novel m-interaction design and evaluation, we hope that future designers will be encouraged to “think out of the box” in terms of their designs and evaluation strategies.

Design of casting entails the knowledge of various interacting factors that are unique to casting process, and, quite often, product designers do not have the required foundry-specific knowledge. Casting designers normally have to liaise with casting experts in order to ensure the product designed is castable and the optimum casting method is selected. This two-way communication results in long design lead times, and lack of it can easily lead to incorrect casting design. A computer-based system at the discretion of a design engineer can, however, alleviate this problem and enhance the prospect of casting design for manufacture. This paper proposes a knowledge-based expert system approach to assist casting product designers in selecting the most suitable casting process for specified casting design requirements, during the design phase of product manufacture. A prototype expert system has been developed, based on production rules knowledge representation technique. The proposed system consists of a number of autonomous but interconnected levels, each dealing with a specific group of factors, namely, casting alloy, shape and complexity parameters, accuracy requirements and comparative costs, based on production quantity. The user interface has been so designed to allow the user to have a clear view of how casting design parameters affect the selection of various casting processes at each level; if necessary, the appropriate design changes can be made to facilitate the castability of the product being designed, or to suit the design to a preferred casting method.

A Case-Based Reasoning (CBR) tool is software that can be used to develop several applications that require cased-based reasoning methodology. CBR shells are kind of application generators with graphical user interface. They can be used by non-programmer users but the extension or integration of new components in these tools is not possible. In this paper we analyzed three CBR object-oriented framework development environments CBR*Tools, CAT-CBR, and JColibri. These frameworks work as open software development environment and facilitate the reuse of their design as well as implementations.

This paper deals with communicational breakdowns and misunderstandings in computer mediated communication (CMC) and ways to recover from them or to prevent them. The paper describes a case study of CMC conducted in a company named Artigiani. We observed communication and conducted content analysis of e-mail messages, focusing on message exchanges between customer service representatives (CSRs) and their contacts. In addition to task management difficulties, we identified communication breakdowns that result from differences between perspectives, and from the lack of contextual information, mainly technical background and professional jargon at the customers’ side. We examined possible ways to enhance CMC and accordingly designed a prototype for an e-mail user interface that emphasizes a communicational strategy called contextualization as a central component for obtaining effective communication and for supporting effective management and control of organizational activities, especially handling orders, price quoting, and monitoring the supply and installation of products.

This paper describes a PC-based mainframe computer emulator called VisibleZ and its use in teaching mainframe Computer Organization and Assembly Programming classes. VisibleZ models IBM’s z/Architecture and allows direct interpretation of mainframe assembly language object code in a graphical user interface environment that was developed in Java. The VisibleZ emulator acts as an interactive visualization tool to simulate enterprise computer architecture. The provided architectural components include main storage, CPU, registers, Program Status Word (PSW), and I/O Channels. Particular attention is given to providing visual clues to the user by color-coding screen components, machine instruction execution, and animation of the machine architecture components. Students interact with VisibleZ by executing machine instructions in a step-by-step mode, simultaneously observing the contents of memory, registers, and changes in the PSW during the fetch-decode-execute machine instruction cycle. The object-oriented design and implementation of VisibleZ allows students to develop their own instruction semantics by coding Java for existing specific z/Architecture machine instructions or design and implement new machine instructions. The use of VisibleZ in lectures, labs, and assignments is described in the paper and supported by a website that hosts an extensive collection of related materials. VisibleZ has been proven a useful tool in mainframe Assembly Language Programming and Computer Organization classes. Using VisibleZ, students develop a better understanding of mainframe concepts, components, and how the mainframe computer works. ACM Computing Classification System (1998): C.0, K.3.2.
