    This project consists on the sensitivity study of mission parameters on the feasibility of the implementation an specific propulsion system, ABEP, in small satellites, specifically Cubesats in order of increasing the orbit they can be on orbit. Also materials will betaken into account to increase the lifetime they remain usable on orbit until they completely degraded. DISCOVEX, a cost model value tool used for the project is briefly explained.The feasibility study results will consist on a comparison of the benefits for different cases, with the reference case simulating the Planet constellation mission. After de comparison of various scenarios, the feasibility of developing and implementing the technologies is discussed

    Reporting experiments to satisfy professionals information needs

    Although the aim of empirical software engineering is to provide evidence for selecting the appropriate technology, it appears that there is a lack of recognition of this work in industry. Results from empirical research only rarely seem to find their way to company decision makers. If information relevant for software managers is provided in reports on experiments, such reports can be considered as a source of information for them when they are faced with making decisions about the selection of software engineering technologies. To bridge this communication gap between researchers and professionals, we propose characterizing the information needs of software managers in order to show empirical software engineering researchers which information is relevant for decision-making and thus enable them to make this information available. We empirically investigated decision makers? information needs to identify which information they need to judge the appropriateness and impact of a software technology. We empirically developed a model that characterizes these needs. To ensure that researchers provide relevant information when reporting results from experiments, we extended existing reporting guidelines accordingly.We performed an experiment to evaluate our model with regard to its effectiveness. Software managers who read an experiment report according to the proposed model judged the technology?s appropriateness significantly better than those reading a report about the same experiment that did not explicitly address their information needs. Our research shows that information regarding a technology, the context in which it is supposed to work, and most importantly, the impact of this technology on development costs and schedule as well as on product quality is crucial for decision makers

    Design Patterns in Software Maintenance: An Experiment Replication at UPM - Experiences with the RESER'11 Joint Replication Project

    Get PDF
    Replication of software engineering experiments is crucial for dealing with validity threats to experiments in this area. Even though the empirical software engineering community is aware of the importance of replication, the replication rate is still very low. The RESER'11 Joint Replication Project aims to tackle this problem by simultaneously running a series of several replications of the same experiment. In this article, we report the results of the replication run at the Universidad Politécnica de Madrid. Our results are inconsistent with the original experiment. However, we have identified possible causes for them. We also discuss our experiences (in terms of pros and cons) during the replication

    A systematic mapping study on testing technique experiments: has the situation changed since 2000?

    Context: Empirical Software Engineering (ESE) replication researchers need to store and manipulate experimental data for several purposes, in particular analysis and reporting. Current research needs call for sharing and preservation of experimental data as well. In a previous work, we analyzed Replication Data Management (RDM) needs. A novel concept, called Experimental Ecosystem, was proposed to solve current deficiencies in RDM approaches. The empirical ecosystem provides replication researchers with a common framework that integrates transparently local heterogeneous data sources. A typical situation where the Empirical Ecosystem is applicable, is when several members of a research group, or several research groups collaborating together, need to share and access each other experimental results. However, to be able to apply the Empirical Ecosystem concept and deliver all promised benefits, it is necessary to analyze the software architectures and tools that can properly support it

    Enriching Requirements Analysis with the Personas Technique

    Get PDF
    A thorough understanding of the users that interact with the system is necessary to develop usable systems. The Personas technique developed by the human-computer interaction (HCI) discipline gathers data about users, gains an understanding of their characteristics, defines fictitious personas based on this understanding and focuses on these personas throughout the software development process. The aim of our research is to build Personas into systems development following software engineering (SE) guidelines. The benefits to be gained are an understanding of the user which is not traditionally taken into account in SE. To do this, we had to undertake two types of tasks. First, we modified the Personas technique to conform to the levels of systematization common in SE. We have called the modified technique PersonaSE. Second, we incorporated the proposed technique into the software requirements analysis proces

    El ámbito en el que se encuentra este Trabajo de Fin de Grado es la disciplina de la electrónica de potencia. Dicha disciplina es la parte de la electrónica encargada de procesar, controlar y convertir las diferentes características de la energía eléctrica mediante dispositivos electrónicos, normalmente semiconductores. Su principal objetivo es la transformación de la energía de una forma eficiente, es decir, dar prioridad al rendimiento y no a la ganancia. Todo esto lo conseguimos principalmente con bobinas y condensadores.Ingeniería Electrónica Industrial y Automátic
