The Innovation Sources in Software Engineering: A Systematic Literature Review

During the last century many researches on the business, marketing and technology fields have developed the innovation research line and large amount of knowledge can be found in the literature. Currently, the importance of systematic and openness approaches to manage the available innovation sources is well established in many knowledge fields. Also in the software engineering sector, where the organizations need to absorb and to exploit as much innovative ideas as possible to get success in the current competitive environment. This Master Thesis presents an study related with the innovation sources in the software engineering eld. The main research goals of this work are the identication and the relevance assessment of the available innovation sources and the understanding of the trends on the innovation sources usage. Firstly, a general review of the literature have been conducted in order to define the research area and to identify research gaps. Secondly, the Systematic Literature Review (SLR) has been proposed as the research method in this work to report reliable conclusions collecting systematically quality evidences about the innovation sources in software engineering field. This contribution provides resources, built-on empirical studies included in the SLR, to support a systematic identication and an adequate exploitation of the innovation sources most suitable in the software engineering field.

Guidance for the development of accessibility evaluation tools following the Unified Software Development Process

Automated and semi-automated accessibility evaluation tools are key to streamline the process of accessibility assessment, and ultimately ensure that software products, contents, and services meet accessibility requirements. Different evaluation tools may better fit different needs and concerns, accounting for a variety of corporate and external policies, content types, invocation methods, deployment contexts, exploitation models, intended audiences and goals; and the specific overall process where they are introduced. This has led to the proliferation of many evaluation tools tailored to specific contexts. However, tool creators, who may be not familiar with the realm of accessibility and may be part of a larger project, lack any systematic guidance when facing the implementation of accessibility evaluation functionalities. Herein we present a systematic approach to the development of accessibility evaluation tools, leveraging the different artifacts and activities of a standardized development process model (the Unified Software Development Process), and providing templates of these artifacts tailored to accessibility evaluation tools. The work presented specially considers the work in progress in this area by the W3C/WAI Evaluation and Report Working Group (ERT WG)

Mandate M 376: new software accessibility requirements

Software needs to be accessible for persons with disabilities and there are several guidelines to assist developers in building more accessible software. Regulation activities are beginning to make the accessibility of software a mandatory requirement in some countries. One such activity is the European Mandate M 376, which will result in a European standard (EN 301 549) defining functional accessibility requirements for information and communication technology products and services. This paper provides an overview of Mandate M 376 and EN 301 549, and describes the requirements for software accessibility defined in EN 301 549, according to a feature-based approach

Mixed-criticality design of a satellite software system

The continuous increment of processors computational power and the requirements on additional functionality and services are motivating a change in the way embedded systems are built. Components with different criticality level are allocated in the same processor, which give rise to mixed-criticality systems. The use of partitioned systems is a way of preventing undesirable interferences between components with different criticality level. An hypervisor provides these partitions or virtual machines, ensuring spatial, temporal and fault isolation between them. The purpose of this paper is to illustrate the development of a mixed-critical system. The attitude control subsystem is used for showing the different steps, which are supported by a toolset developed in the context of the MultiPARTES research project.

Software architecture implementation based on OpenSim

One of the objectives of the European Higher Education Area is the promotion of collaborative and informal learning through the implementation of educational practices. 3D virtual environments become an ideal space for such activities. On the other hand, the problem of financing in Spanish universities has led to the search for new ways to optimize available resources. The Technical University of Madrid requires the use of laboratories which due to their dangerousness, duration or control of the developed processes are difficult to perform in real life. For this reason, we have developed several 3D laboratories in virtual environment. The laboratories are built on open source platform OpenSim. In this paper it is exposed the use of the OpenSim platform for these new teaching experiences and the new design of the software architecture. This architecture requires the adaptation of the platform to the needs of the users and the different laboratories of our University. We will explain the structure of the implemented architecture and the process of creating and configuring it. The proposed architecture is decentralized, each laboratory is housed in different an educational center. The architecture adds several services, among others, the creation and management of users automated, communication between external services and platforms in different program languages. Therefore, we achieve improving the user experience and rising the functionalities of laboratories.

Accessible interaction solution based on confidence for the deployment of pervasive sensitive services in intelligent environments

Los servicios basados en las Tecnologías de la Información y las Comunicaciones (TIC) están cada vez más presentes en la vida de las personas. El avance de las TIC en términos técnicos y de aceptación social ha dado lugar la creación de nuevos modelos de provisión de servicios. Estos modelos de servicio implican una mayor integración con las actividades de las personas de forma que ya no solo están presentes en su ámbito profesional o de espacio ciudadano sino también en un ámbito más íntimo relacionado con su propia identidad. Así en la actualidad es común encontrar servicios conocedores del estado de salud de las personas, sus hábitos domésticos, su ideología, etc. Por tanto el análisis de los servicios actuales no puede limitarse a una componente técnica sino que es más necesario que nunca la inclusión de aspectos más relacionados con la forma de ser y sentir de sus usuarios. De esta forma no solo se garantizará la corrección técnica de sus funcionalidades sino que también se fomentará la generación de soluciones cívicamente seguras y respetuosas tanto con los derechos como con la forma de ser y sentir de sus usuarios. Desde el punto de vista de ingeniería, la perspectiva del usuario se ha englobado históricamente bajo el concepto de aceptación tecnológica. Dentro de este ámbito se puede interpretar que soluciones respetuosas y adaptadas a los usuarios fomentarán la aceptación por parte de éstos. La aceptación de una solución es algo deseable si bien es difícil de asegurar. Esta dificultad es debida al desconocimiento del número de variables que afectan a la aceptación de soluciones tecnológicas y a la dificultad de optimización de las variables conocidas. En esta tesis doctoral se estudia y caracteriza una de las variables que afecta a la aceptación de los servicios actuales: la confianza. Se define la confianza en términos psicológicos caracterizándola para permitir su uso en los métodos propios de la ingeniería. Además se proponen distintas herramientas que facilitan la optimización de la confianza en servicios cuya complejidad convierte a esta variable en una cuestión básica para mejorar la aceptación. Como contexto de trabajo para la tesis se ha escogido un servicio de salud desplegado en un hogar. Este escenario presenta una serie de restricciones de aceptación relativas a la tecnología utilizada para la creación de los servicios y la forma en que éstos gestionan la información adquirida del usuario. Se trata de servicios altamente sensibles y deslocalizados que pueden afectar a la percepción del usuario sobre el entorno, el hogar, y generar temores o rechazos que impidan su adopción final como solución válida. Una vez definido el marco genérico de trabajo, el objetivo principal de esta tesis doctoral se concreta en contribuir al fomento de la aceptación de nuevos servicios de salud pervasivos y personalizados y su despliegue en entornos inteligentes domésticos mediante un marco de diseño que promueva un estado psicológico de confianza en los usuarios. Para lograr abordar correctamente este objetivo se han proporcionado una serie de resultados tanto a nivel conceptual como tecnológico y experimental. En concreto se ha ofrecido una caracterización completa del sentimiento de confianza desde un punto de vista de ingeniería y una definición del concepto de servicio sensible deslocalizado o pervasivo. Además se ofrece un método para la inclusión del Diseño de Interacción, herramienta muy relacionada con la mejora de las variables de aceptación de tecnología, en los procesos de ingeniería de este tipo de servicios mediante un conjunto de patrones de interacción Persona – Entorno Inteligente. Finalmente se ha proporcionado el desarrollo de una arquitectura software para garantizar el correcto despliegue de estos servicios sensibles pervasivos en espacios inteligentes de una forma confiable. La discusión de los resultados obtenidos sugiere la extensión del modelo a diferentes servicios de la Sociedad de la Información que manejen datos sensibles tanto en el contexto del Hogar Digital como otros contextos donde el usuario realice actividades cotidianas, como los espacios de trabajo o los centros educativos. Las líneas de trabajo futuras contemplan la necesidad inminente de aplicar los resultados a desarrollos en curso, dentro de proyectos de investigación en los que participa el autor así como el desarrollo de nuevas líneas de investigación orientadas a la generación de nuevos espacios y tecnologías de interacción como el Colegio Digital, juguetes del futuro, sistemas de visualización confiables o sistemas de seguridad basados en el estado de las personas.

Configuración de un entorno de trabajo para el desarrollo de software ágil con integración continua

Hoy en día, existen numerosos sistemas (financieros, fabricación industrial, infraestructura de servicios básicos, etc.) que son dependientes del software. Según la definición de Ingeniería del Software realizada por I. Sommerville, “la Ingeniería del Software es una disciplina de la ingeniería que comprende todos los aspectos de la producción de software desde las etapas iniciales de la especificación del sistema, hasta el mantenimiento de éste después de que se utiliza.” “La ingeniería del software no sólo comprende los procesos técnicos del desarrollo de software, sino también actividades tales como la gestión de proyectos de software y el desarrollo de herramientas, métodos y teorías de apoyo a la producción de software.” Los modelos de proceso de desarrollo software determinan una serie de pautas para poder desarrollar con éxito un proyecto de desarrollo software. Desde que surgieran estos modelos de proceso, se investigado en nuevas maneras de poder gestionar un proyecto y producir software de calidad. En primer lugar surgieron las metodologías pesadas o tradicionales, pero con el avance del tiempo y la tecnología, surgieron unas nuevas llamadas metodologías ágiles. En el marco de las metodologías ágiles cabe destacar una determinada práctica, la integración continua. Esta práctica surgió de la mano de Martin Fowler, con el objetivo de facilitar el trabajo en grupo y automatizar las tareas de integración. La integración continua se basa en la construcción automática de proyectos con una frecuencia alta, promoviendo la detección de errores en un momento temprano para poder dar prioridad a corregir dichos errores. Sin embargo, una de las claves del éxito en el desarrollo de cualquier proyecto software consiste en utilizar un entorno de trabajo que facilite, sistematice y ayude a aplicar un proceso de desarrollo de una forma eficiente. Este Proyecto Fin de Grado (PFG) tiene por objetivo el análisis de distintas herramientas para configurar un entorno de trabajo que permita desarrollar proyectos aplicando metodologías ágiles e integración continua de una forma fácil y eficiente. Una vez analizadas dichas herramientas, se ha propuesto y configurado un entorno de trabajo para su puesta en marcha y uso. Una característica a destacar de este PFG es que las herramientas analizadas comparten una cualidad común y de alto valor, son herramientas open-source. El entorno de trabajo propuesto en este PFG presenta una arquitectura cliente-servidor, dado que la mayoría de proyectos software se desarrollan en equipo, de tal forma que el servidor proporciona a los distintos clientes/desarrolladores acceso al conjunto de herramientas que constituyen el entorno de trabajo. La parte servidora del entorno propuesto proporciona soporte a la integración continua mediante herramientas de control de versiones, de gestión de historias de usuario, de análisis de métricas de software, y de automatización de la construcción de software. La configuración del cliente únicamente requiere de un entorno de desarrollo integrado (IDE) que soporte el lenguaje de programación Java y conexión con el servidor. ABSTRACT Nowadays, numerous systems (financial, industrial production, basic services infrastructure, etc.) depend on software. According to the Software Engineering definition made by I.Sommerville, “Software engineering is an engineering discipline that is concerned with all aspects of software production from the early stages of system specification through to maintaining the system after it has gone into use.” “Software engineering is not just concerned with the technical processes of software development. It also includes activities such as software project management and the development of tools, methods, and theories to support software production.” Software development process models determine a set of guidelines to successfully develop a software development project. Since these process models emerged, new ways of managing a project and producing software with quality have been investigated. First, the so-called heavy or traditional methodologies appeared, but with the time and the technological improvements, new methodologies emerged: the so-called agile methodologies. Agile methodologies promote, among other practices, continuous integration. This practice was coined by Martin Fowler and aims to make teamwork easier as well as automate integration tasks. Nevertheless, one of the keys to success in software projects is to use a framework that facilitates, systematize, and help to deploy a development process in an efficient way. This Final Degree Project (FDP) aims to analyze different tools to configure a framework that enables to develop projects by applying agile methodologies and continuous integration in an easy and efficient way. Once tools are analyzed, a framework has been proposed and configured. One of the main features of this FDP is that the tools under analysis share a common and high-valued characteristic: they are open-source. The proposed framework presents a client-server architecture, as most of the projects are developed by a team. In this way, the server provides access the clients/developers to the tools that comprise the framework. The server provides continuous integration through a set of tools for control management, user stories management, software quality management, and software construction automatization. The client configuration only requires a Java integrated development environment and network connection to the server.

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.

Economic crisis, immigrant women and changing availability of intimate partner violence services: a qualitative study of professionals' perceptions in Spain

Introduction: Since 2008, Spain has been in the throes of an economic crisis. This recession particularly affects the living conditions of vulnerable populations, and has also led to a reversal in social policies and a reduction in resources. In this context, the aim of this study was to explore intimate partner violence (IPV) service providers’ perceptions of the impact of the current economic crisis on these resources in Spain and on their capacity to respond to immigrant women’s needs experiencing IPV. Methods: A qualitative study was performed based on 43 semi-structured in-depth interviews to social workers, psychologists, intercultural mediators, judges, lawyers, police officers and health professionals from different services dealing with IPV (both, public and NGO’s) and cities in Spain (Barcelona, Madrid, Valencia and Alicante) in 2011. Transcripts were imported into qualitative analysis software (Atlas.ti), and analysed using qualitative content analysis. Results: We identified four categories related to the perceived impact of the current economic crisis: a) “Immigrant women have it harder now”, b) “IPV and immigration resources are the first in line for cuts”, c) “ Fewer staff means a less effective service” and d) “Equality and IPV policies are no longer a government priority”. A cross-cutting theme emerged from these categories: immigrant women are triply affected; by IPV, by the crisis, and by structural violence. Conclusion: The professionals interviewed felt that present resources in Spain are insufficient to meet the needs of immigrant women, and that the situation might worsen in the future.

SubCM: A tool for improved visibility of software change in an industrial setting

Software Configuration Management is the discipline of managing large collections of software development artefacts from which software products are built. Software configuration management tools typically deal with artefacts at fine levels of granularity - such as individual source code files - and assist with coordination of changes to such artefacts. This paper describes a lightweight tool, designed to be used on top of a traditional file-based configuration management system. The add-on tool support enables users to flexibly define new hierarchical views of product structure, independent of the underlying artefact-repository structure. The tool extracts configuration and change data with respect to the user-defined hierarchy, leading to improved visibility of how individual subsystems have changed. The approach yields a range of new capabilities for build managers, and verification and validation teams. The paper includes a description of our experience using the tool in an organization that builds large embedded software systems.
