Definición e implementación de un sistema de información para un proceso de desarrollo de software
En un entorno donde las exigencias del cliente son cada vez mayores, donde los cambios
en los negocios son cada vez más rápidos, las empresas tienden a tener una mayor
dependencia de las Tecnologías de la Información (TI).
Los departamentos de TI de las empresas, y las actividades en ellos desarrolladas, han
sido tradicionalmente vistos como procesos de soporte al negocio, descuidando muchas
veces el uso de criterios racionales para medir su rentabilidad, eficacia y la calidad del
servicio ofrecidos.
Durante años, muchos departamentos de TI han intentado hacer frente al crecimiento de la
carga de gestión introduciendo más empleados y tecnología, cuando lo más indicado es
acometer una profunda transformación de sus procesos, que generalmente conservan una
naturaleza estrictamente reactiva. Esta mejora contínua requiere, por parte de los
responsables de la toma de decisiones, tener un conocimiento cercano y preciso de lo que
sucede en la organización por lo que es necesario dotar a estas personas de información
estructurada acerca del funcionamiento de los procesos. Información cuantitativa y
cualitativa que debe extraerse automáticamente de los sistemas corporativos.
Se trata generar orden, lenguaje y procesos comunes, optimizar beneficios y garantizar la
integración de los servicios en la cadena de valor de las unidades de negocio. Para
lograrlo, no basta con desarrollar un modelo de gestión basado en procesos de negocio,
también conocido cómo modelo BPM (del inglés, Business Process Management) sinó que
es fundamental contar con personas que tengan el conocimiento necesario e implementar
Sistemas de gestión de la Información.
Para ello, en este proyecto trataremos de definir e implantar un modelo de gestión basado
en el Proceso de Desarrollo de Software de un departamento de TI. Para ello, definiremos
los procedimientos a implantar, la estructura organizativa, los protocolos de comunicación,
etc…
Una vez definido el modelo de gestión, pasaremos a definir un sistema de indicadores que
estructure la información generada por los sistemas corporativos y herramientas de apoyo
en un panel de mando que facilite a los responsables la toma de decisiones a través de
planes de acción predefinidos en función de las situaciones.
Finalmente, realizaremos una prueba piloto mediante un panel de mando de la gestión de

Observation of a valence transition in (Pr,Ca)CoO3 cobaltites: charge migration at the metal-insulator transition
X-ray absorption spectroscopy measurements in Pr0.5Ca0.5CoO3 and
(Pr,Y)0.55Ca0.45CoO3 compositions reveal that the valence of praseodymium ions
is stable and essentially +3 (Pr [4f 2]) in the metallic state, but abruptly
changes when carriers localize approaching the oxidation state +4 (Pr [4f 1]).
This mechanism appears to be the driving force of the metal-insulator
transition. The ground insulating state of Pr0.5Ca0.5CoO3 is an homogeneous
Co3.5-d state stabilized by a charge transfer from Pr to Co sites: 1/2Pr3+ +
Co3.5 \to 1/2Pr3+2d + Co3.5-d, with 2d \approx 0.26 e-.Comment: Submitted. 14 pages, 4 Figure
Enhancing controller's tuning reliability with multi-objective optimisation: From Model in the loop to Hardware in the loop
[EN] In general, the starting point for the complex task of designing a robust and efficient control system is the use of nominal models that allow to establish a first set of parameters for the selected control scheme. Once the initial stage of design is achieved, control engineers face the difficult task of Fine-Tuning for a more realistic environment, where the environment conditions are as similar as possible to the real system. For this reason, in the last decades the use of Hardware-in-The-Loop (HiL) systems has been introduced. This simulation technique guarantees realistic simulation environments to test the designs but without danger of damaging the equipment. Also, in this iterative process of Fine-Tuning, it is usual to use different (generally conflicting/opposed) criteria that take into account the sensitivities that always appear in every project, such as economic, security, robustness, performance, for example. In this framework, the use of multi-objective techniques are especially useful since they allow to study the different design alternatives based on the multiple existing criteria. Unfortunately, the combination of multi-objective techniques and verification schemes based on Hardware-In-The-Loop presents a high incompatibility. Since obtaining the optimal set of solutions requires a high computational cost that is greatly increased when using Hardware- In-the-Loop. For this reason, it is often necessary to use less realistic but more computationally efficient verification schemes such as Model in the Loop (MiL), Software in the Loop (SiL) and Processor in the Loop (PiL). In this paper, a combined methodology is presented, where multi-objective optimisation and multi-criteria decision making steps are sequentially performed to achieve a final control solution. The authors claim that while going towards the optimisation sequence over MiL -> SiL -> PiL -> HiL platforms, the complexity of the problem is unveiled to the designer, allowing to state meaningful design objectives. In addition, safety in the step between simulation and reality is significantly increased.The authors would like to acknowledge the Spanish Ministry of Economy and Competitiveness for providing funding through the project DPI2015-71443-R and the grant BES-2012-056210.

Zn-biofortification enhanced nitrogen metabolism and photorespiration process in green leafy vegetable Lactuca sativa L
Abstract
BACKGROUND: Excessive rates of nitrogen (N) fertilizers may result in elevated concentrations of nitrate (NO3
−) in plants.
Considering thatmany programs of biofortification with trace elements are being performed, it has become important to study
how the application of these elements affects plant physiology and, particularly, N utilization in leaf crops. The main objective
of the present study was to determine whether the NO3
− accumulation and the nitrogen use efficiency was affected by the
application of different doses of Zn in Lactuca sativa plants.
RESULTS: Zn doses in the range 80–100 mol L−1 produced an increase in Zn concentration provoking a decrease of NO3
−
concentration and increase of the nitrate reductase, glutamine synthetase and aspartate aminotransferase activities, as well
as the photorespiration processes. As result, we observed an increase in reduced N, total N concentration and N utilization
efficiency. Consequently, at a dose of 80 mol L−1 of Zn, the amino acid concentration increased significantly.
CONCLUSION: Adequate Zn fertilization is an important critical player in lettuce, especially at a dose of 80 mol L−1 of Zn,
because it could result in an increase in the Zn concentration, a reduction of NO3
− levels and an increase the concentration of
essential amino acids, with all of them having beneficial properties for the human diet
Controller tuning by means of multi-objective optimization algorithms: a global tuning framework

This approach gives control engineers greater flexibility to select a controller that matches their specifications. Furthermore, for a given controller it is simple to analyze the tradeoff achieved between conflicting objectives. By using the multi-objective design technique it is also possible to perform a global comparison between different control strategies in a simple and robust way. This approach thereby enables an analysis to be made of whether a preference for a certain control technique is justified. This proposal is evaluated and validated in a nonlinear multiple-input multiple-output system using two control strategies: a classical proportional- integral-derivative control scheme and a feedback state controller.This work was supported in part by the FPI-2010/19 Grant and the Project PAID-06-11 from the Universitat Politecnica de Valencia and in part by the Projects DPI2008-02133, TIN2011-28082, and ENE2011-25900 from the Spanish Ministry of Science and Innovation.Reynoso Meza, G.; García-Nieto Rodríguez, S.; Sanchís Saez, J.; Blasco, X.

Xf-Rovim. A Field Robot to Detect Olive Trees Infected by Xylella Fastidiosa Using Proximal Sensing
[EN] The use of remote sensing to map the distribution of plant diseases has evolved considerably
over the last three decades and can be performed at different scales, depending on the area to
be monitored, as well as the spatial and spectral resolution required. This work describes the
development of a small low-cost field robot (Remotely Operated Vehicle for Infection Monitoring in
orchards, XF-ROVIM), which is intended to be a flexible solution for early detection of Xylella fastidiosa
(X. fastidiosa) in olive groves at plant to leaf level. The robot is remotely driven and fitted with different
sensing equipment to capture thermal, spectral and structural information about the plants. Taking
into account the height of the olive trees inspected, the design includes a platform that can raise the
cameras to adapt the height of the sensors to a maximum of 200 cm. The robot was tested in an olive
grove (4 ha) potentially infected by X. fastidiosa in the region of Apulia, southern Italy. The tests were
focused on investigating the reliability of the mechanical and electronic solutions developed as well
as the capability of the sensors to obtain accurate data. The four sides of all trees in the crop were
inspected by travelling along the rows in both directions, showing that it could be easily adaptable to
other crops. XF-ROVIM was capable of inspecting the whole field continuously, capturing geolocated
spectral information and the structure of the trees for later comparison with the in situ observations.This work was partially supported by funding from the European Union's Horizon 2020 research and innovation programme under grant agreement 727987 Xylella Fastidiosa Active Containment Through a multidisciplinary-Oriented Research Strategy (XF-ACTORS).Rey, B.; Aleixos Borrás, MN.; Cubero-García, S.; Blasco Ivars, J.
