Técnicas de diseño de pruebas en sistemas embebidos

El software es, cada vez más, una parte muy importante de cualquier circuito electrónico moderno, por ejemplo, un circuito realizado con algún tipo de microprocesador debe incorporar un programa de control por pequeño que sea. Al utilizarse programas informáticos en los circuitos electrónicos modernos, es muy aconsejable, por no decir imprescindible, realizar una serie de pruebas de calidad del diseño realizado. Estas pruebas son cada vez más complicadas de realizar debido al gran tamaño del software empleado en los sistemas actuales, por este motivo, es necesario estructurar una serie de pruebas con el fin de realizar un sistema de calidad, y en algunos casos, un sistema que no presente ningún peligro para el ser humano o el medio ambiente. Esta propuesta consta de la explicación de las técnicas de diseño de pruebas que existen actualmente (por lo menos las más básicas ya que es un tema muy extenso) para realizar el control de calidad del software que puede contener un sistema embebido. Además, muchos circuitos electrónicos, debido a su control o exigencia hardware, es imprescindible que sean manipulados por algún programa que requiera más que un simple microprocesador, me refiero a que se deban controlar por medio de un pequeño programa manipulado por un sistema operativo, ya sea Linux, AIX, Unix, Windows, etc., en este caso el control de calidad se debería llevar a cabo con otras técnicas de diseño. También se puede dar el caso que el circuito electrónico a controlar se deba hacer por medio de una página web. El objetivo es realizar un estudio de las actuales técnicas de diseño de pruebas que están orientadas al desarrollo de sistemas embebidos. ABSTRACT. Software is increasingly a very important part of any modern electronic circuit, for example, a circuit made with some type of microprocessor must incorporate a control program no matter the small it is. When computer programs are used in modern electronic circuits, it is quite advisable if not indispensable to perform a series of quality tests of the design. These tests are becoming more and more difficult to be performed due to the large size of the software used in current systems, which is why it is necessary to structure a series of tests in order to perform a quality system, and in some cases, a system with no danger to humans or to the environment. This proposal consists of an explanation of the techniques used in the tests (at least the most basic ones since it is a very large topic) for quality control of software which may contain an embedded system. In addition, a lot of electronic circuits, due to its control or required hardware, it is essential to be manipulated by a program that requires more than a simple microprocessor, I mean that they must be controlled by means of a small program handled by an operating system, being Linux, AIX, Unix, Windows, etc., in this case the quality control should be carried out with other design techniques. The objective is to study the current test design techniques that are geared to the development of embedded systems. It can also occur that the electronic circuit should be controlled by means of a web page.

Desarrollo e implementación de un sistema robótico aéreo con programación tridimensional orientado al recorrido de rutas

En la actualidad se estudia en numerosos campos cómo automatizar distintas tareas ejecutadas por aeronaves con tripulación humana. Estas tareas son en todos los casos muy costosos, debido al gran consumo de combustible, gran coste de adquisición y mantenimiento de la propia aeronave, todo ello sin contar el riesgo para los mismos tripulantes. Como ejemplo de estas tareas se puede incluir la vigilancia policial y fronteriza, revisiones de tendidos de alta tensión, la alerta temprana de incendios forestales y la medición de parámetros contaminantes. El objetivo de este proyecto es el diseño y la construcción de un prototipo electrónico empotrado basado en microcontrolador con núcleo C8051 de Silicon labs, que sea capaz de gobernar una aeronave de radiocontrol de forma transparente, de manera que en un futuro se pueda sustituir el propio aeromodelo, con la modificación de algunos parámetros, para poder incorporar sistemas de video o distintos medios de detección de variables. El prototipo seguirá una ruta confeccionada y transferida como un archivo de texto con un formato determinado que contendrá los datos necesarios para poder navegar mediante GPS. El trabajo con los modelos de motorización térmica (motores de combustión interna tipo glow, en este caso) resulta peligroso debido a la gran energía que son capaces de alcanzar. A fin de mantener la máxima seguridad durante la evolución del proyecto, se ha diseñado un proceso de tres partes independientes que permitan la correcta familiarización de los distintos componentes que se emplearán. Las fases son las siguientes: 1. Test y modelado de todos los componentes mediante pequeños montajes con protoboard de inserción y programas individuales. Se realizará mediante una tarjeta multipropósito que contendrá un microcontrolador similar en características, aunque de menor complejidad, al del prototipo final. 2. Integración de todos los componentes mediante una tarjeta especialmente diseñada que servirá de interfaz entre la tarjeta multipropósito y todo el hardware necesario para el control de un vehículo terrestre de iguales características (actuadores y motorización) al aeromodelo. 3. Diseño de un sistema embebido que concentre todos los subsistemas desarrollados en las fases anteriores y que integre todos los componentes necesarios para el gobierno de una aeronave de ala fija. ABSTRACT. Nowadays, the way of automating different tasks done by manned vehicles is studied. These tasks are any case very expensive, due to large fuel consumption, costs of aircraft buying, without taking into account the risk for human crew. As an example of these tasks, we can include policing or border surveillance, maintenance of high voltage lines, early warning of forest fire and measuring of pollution parameters. The target of this project is the design and construction of an embedded electronic prototype, based on a microcontroller with C8051 core from Silicon labs, and it will be able to controlling an aircraft transparently, in order that in the future the flying model could be changed with the modification of some parameters, and video or any variables detection systems could be added. The prototype will follow a designed and transferred path as an plain text file with a given format, that will contain all the necessary data for GPS navigation. Working with heat engine models (internal combustion engine, glow type, in this case) becomes dangerous due to the large energy that can be able to acquire. In order to keep the maximum safety level during the project evolution a three independent stages process have been designed, this allows familiarizing properly with the parts that will be used. The stages are as follows: 1. Test and modeling of all of the parts by little assemblies with through-hole protoboard and stand alone programs. It will be done with a multipurpose card which contains a microcontroller of similar characteristics, although less complex, of the final prototype. 2. Integrating of all of parts through a dedicated design card that will serve as interface between multipurpose card and all the necessary hardware for controlling a ground vehicle with the same characteristics (actuators and engine) of the flying model. 3. Embedded system designing that contains all the developed subsystems in the previous stages and integrates all the necessary parts for controlling a fixed-wing aircraft.

SMART Protocols: seMAntic represenTation for experimental protocols

Two important characteristics of science are the ?reproducibility? and ?clarity?. By rigorous practices, scientists explore aspects of the world that they can reproduce under carefully controlled experimental conditions. The clarity, complementing reproducibility, provides unambiguous descriptions of results in a mechanical or mathematical form. Both pillars depend on well-structured and accurate descriptions of scientific practices, which are normally recorded in experimental protocols, scientific workflows, etc. Here we present SMART Protocols (SP), our ontology-based approach for representing experimental protocols and our contribution to clarity and reproducibility. SP delivers an unambiguous description of processes by means of which data is produced; by doing so, we argue, it facilitates reproducibility. Moreover, SP is thought to be part of e-science infrastructures. SP results from the analysis of 175 protocols; from this dataset, we extracted common elements. From our analysis, we identified document, workflow and domain-specific aspects in the representation of experimental protocols. The ontology is available at http://purl.org/net/SMARTprotocol

PCCMuTe v2.2: una herramienta para medir el consumo de energía en sistemas empotrados

Este Proyecto Fin de Grado (PFG) recoge el trabajo de depuración realizado sobre el prototipo PCCMuTe v2.2, un sistema empotrado que dispone de la instrumentación necesaria para medir el consumo de potencia/energía en cada uno de sus dominios de tensión, y posteriormente digitalizar y enviar los resultados al procesador que se encuentra en su interior. Su uso permite la obtención de información en tiempo real sobre el consumo del hardware de la placa, en especial del procesador, pudiendo relacionar la potencia consumida con el software ejecutado. El proyecto está orientado a medir el consumo de energía derivado de la decodificación de vídeo. El software utilizado para controlar el hardware se basa en Linux. En este proyecto se distinguen principalmente dos actividades, depuración hardware y depuración software. Los resultados muestran avances en la depuración hardware hasta obtener un prototipo en completo funcionamiento. Los avances en el apartado del software habilitan las comunicaciones SPI, necesarias para la transmisión de los resultados de consumo al procesador. En la fase final de este PFG se hace uso de una aplicación previamente desarrollada por miembros del GDEM con la que se obtienen los primeros datos de consumo, pero por falta de tiempo estos resultados no pueden ser verificados. Por la misma razón no ha sido posible diseñar y codificar una nueva aplicación que mejore la forma en la que se obtienen esos datos. ABSTRACT. This bachelor final project includes the debugging work done on the prototype PCCMuTe v2.2, an embedded system with the necessary instrumentation to measure the power/ energy consumption in each of its voltage domains, scan and send the results to its processor. The purpose of this device is to obtain real-time information about the hardware power consumption, especially from the processor, being able to relate the power consumed with the software executed. The project aims to measure the energy consumption of video decoding. The software used to control the hardware is based on Linux. In this project there are two main activities: hardware and software debugging. The results show advances in hardware debugging, and finally a fully functioning prototype is obtained. Advances in software debugging enable SPI communications, used to transmit the consumption data to the processor. In the last part of this final bachelor project an application previously coded by other members of the GDEM is used to obtain the first data. The results can not finally be verified because of the lack of time. For the same reason it is not possible to design and code a new application that improves the way the data is obtained.

Methodology for developing a Speech into Sign Language Translation System in a New Semantic Domain

This paper proposes a methodology for developing a speech into sign language translation system considering a user-centered strategy. This method-ology consists of four main steps: analysis of technical and user requirements, data collection, technology adaptation to the new domain, and finally, evalua-tion of the system. The two most demanding tasks are the sign generation and the translation rules generation. Many other aspects can be updated automatical-ly from a parallel corpus that includes sentences (in Spanish and LSE: Lengua de Signos Española) related to the application domain. In this paper, we explain how to apply this methodology in order to develop two translation systems in two specific domains: bus transport information and hotel reception.

Factored Translation Models for improving a Speech into Sign Language Translation System

This paper proposes the use of Factored Translation Models (FTMs) for improving a Speech into Sign Language Translation System. These FTMs allow incorporating syntactic-semantic information during the translation process. This new information permits to reduce significantly the translation error rate. This paper also analyses different alternatives for dealing with the non-relevant words. The speech into sign language translation system has been developed and evaluated in a specific application domain: the renewal of Identity Documents and Driver’s License. The translation system uses a phrase-based translation system (Moses). The evaluation results reveal that the BLEU (BiLingual Evaluation Understudy) has improved from 69.1% to 73.9% and the mSER (multiple references Sign Error Rate) has been reduced from 30.6% to 24.8%.

Adapting a speech into sign language translation system to a new domain

This paper presents a methodology for adapting an advanced communication system for deaf people in a new domain. This methodology is a user-centered design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. In this paper, the new considered domain has been the dialogues in a hotel reception. With this methodology, it was possible to develop the system in a few months, obtaining very good performance: good speech recognition and translation rates (around 90%) with small processing times.

Automatic Categorization for Improving Spanish into Spanish Sign Language Machine Translation

This paper describes a preprocessing module for improving the performance of a Spanish into Spanish Sign Language (Lengua de Signos Espanola: LSE) translation system when dealing with sparse training data. This preprocessing module replaces Spanish words with associated tags. The list with Spanish words (vocabulary) and associated tags used by this module is computed automatically considering those signs that show the highest probability of being the translation of every Spanish word. This automatic tag extraction has been compared to a manual strategy achieving almost the same improvement. In this analysis, several alternatives for dealing with non-relevant words have been studied. Non-relevant words are Spanish words not assigned to any sign. The preprocessing module has been incorporated into two well-known statistical translation architectures: a phrase-based system and a Statistical Finite State Transducer (SFST). This system has been developed for a specific application domain: the renewal of Identity Documents and Driver's License. In order to evaluate the system a parallel corpus made up of 4080 Spanish sentences and their LSE translation has been used. The evaluation results revealed a significant performance improvement when including this preprocessing module. In the phrase-based system, the proposed module has given rise to an increase in BLEU (Bilingual Evaluation Understudy) from 73.8% to 81.0% and an increase in the human evaluation score from 0.64 to 0.83. In the case of SFST, BLEU increased from 70.6% to 78.4% and the human evaluation score from 0.65 to 0.82.

Energy and power aware scheduling algorithm modeling for battery powered embedded systems

Energy management has always been recognized as a challenge in mobile systems, especially in modern OS-based mobile systems where multi-functioning are widely supported. Nowadays, it is common for a mobile system user to run multiple applications simultaneously while having a target battery lifetime in mind for a specific application. Traditional OS-level power management (PM) policies make their best effort to save energy under performance constraint, but fail to guarantee a target lifetime, leaving the painful trading off between the total performance of applications and the target lifetime to the user itself. This thesis provides a new way to deal with the problem. It is advocated that a strong energy-aware PM scheme should first guarantee a user-specified battery lifetime to a target application by restricting the average power of those less important applications, and in addition to that, maximize the total performance of applications without harming the lifetime guarantee. As a support, energy, instead of CPU or transmission bandwidth, should be globally managed as the first-class resource by the OS. As the first-stage work of a complete PM scheme, this thesis presents the energy-based fair queuing scheduling, a novel class of energy-aware scheduling algorithms which, in combination with a mechanism of battery discharge rate restricting, systematically manage energy as the first-class resource with the objective of guaranteeing a user-specified battery lifetime for a target application in OS-based mobile systems. Energy-based fair queuing is a cross-application of the traditional fair queuing in the energy management domain. It assigns a power share to each task, and manages energy by proportionally serving energy to tasks according to their assigned power shares. The proportional energy use establishes proportional share of the system power among tasks, which guarantees a minimum power for each task and thus, avoids energy starvation on any task. Energy-based fair queuing treats all tasks equally as one type and supports periodical time-sensitive tasks by allocating each of them a share of system power that is adequate to meet the highest energy demand in all periods. However, an overly conservative power share is usually required to guarantee the meeting of all time constraints. To provide more effective and flexible support for various types of time-sensitive tasks in general purpose operating systems, an extra real-time friendly mechanism is introduced to combine priority-based scheduling into the energy-based fair queuing. Since a method is available to control the maximum time one time-sensitive task can run with priority, the power control and time-constraint meeting can be flexibly traded off. A SystemC-based test-bench is designed to assess the algorithms. Simulation results show the success of the energy-based fair queuing in achieving proportional energy use, time-constraint meeting, and a proper trading off between them. La gestión de energía en los sistema móviles está considerada hoy en día como un reto fundamental, notándose, especialmente, en aquellos terminales que utilizando un sistema operativo implementan múltiples funciones. Es común en los sistemas móviles actuales ejecutar simultaneamente diferentes aplicaciones y tener, para una de ellas, un objetivo de tiempo de uso de la batería. Tradicionalmente, las políticas de gestión de consumo de potencia de los sistemas operativos hacen lo que está en sus manos para ahorrar energía y satisfacer sus requisitos de prestaciones, pero no son capaces de proporcionar un objetivo de tiempo de utilización del sistema, dejando al usuario la difícil tarea de buscar un compromiso entre prestaciones y tiempo de utilización del sistema. Esta tesis, como contribución, proporciona una nueva manera de afrontar el problema. En ella se establece que un esquema de gestión de consumo de energía debería, en primer lugar, garantizar, para una aplicación dada, un tiempo mínimo de utilización de la batería que estuviera especificado por el usuario, restringiendo la potencia media consumida por las aplicaciones que se puedan considerar menos importantes y, en segundo lugar, maximizar las prestaciones globales sin comprometer la garantía de utilización de la batería. Como soporte de lo anterior, la energía, en lugar del tiempo de CPU o el ancho de banda, debería gestionarse globalmente por el sistema operativo como recurso de primera clase. Como primera fase en el desarrollo completo de un esquema de gestión de consumo, esta tesis presenta un algoritmo de planificación de encolado equitativo (fair queueing) basado en el consumo de energía, es decir, una nueva clase de algoritmos de planificación que, en combinación con mecanismos que restrinjan la tasa de descarga de una batería, gestionen de forma sistemática la energía como recurso de primera clase, con el objetivo de garantizar, para una aplicación dada, un tiempo de uso de la batería, definido por el usuario, en sistemas móviles empotrados. El encolado equitativo de energía es una extensión al dominio de la energía del encolado equitativo tradicional. Esta clase de algoritmos asigna una reserva de potencia a cada tarea y gestiona la energía sirviéndola de manera proporcional a su reserva. Este uso proporcional de la energía garantiza que cada tarea reciba una porción de potencia y evita que haya tareas que se vean privadas de recibir energía por otras con un comportamiento más ambicioso. Esta clase de algoritmos trata a todas las tareas por igual y puede planificar tareas periódicas en tiempo real asignando a cada una de ellas una reserva de potencia que es adecuada para proporcionar la mayor de las cantidades de energía demandadas por período. Sin embargo, es posible demostrar que sólo se consigue cumplir con los requisitos impuestos por todos los plazos temporales con reservas de potencia extremadamente conservadoras. En esta tesis, para proporcionar un soporte más flexible y eficiente para diferentes tipos de tareas de tiempo real junto con el resto de tareas, se combina un mecanismo de planificación basado en prioridades con el encolado equitativo basado en energía. En esta clase de algoritmos, gracias al método introducido, que controla el tiempo que se ejecuta con prioridad una tarea de tiempo real, se puede establecer un compromiso entre el cumplimiento de los requisitos de tiempo real y el consumo de potencia. Para evaluar los algoritmos, se ha diseñado en SystemC un banco de pruebas. Los resultados muestran que el algoritmo de encolado equitativo basado en el consumo de energía consigue el balance entre el uso proporcional a la energía reservada y el cumplimiento de los requisitos de tiempo real.

Design, development and field evaluation of a Spanish into sign language translation system

This paper describes the design, development and field evaluation of a machine translation system from Spanish to Spanish Sign Language (LSE: Lengua de Signos Española). The developed system focuses on helping Deaf people when they want to renew their Driver’s License. The system is made up of a speech recognizer (for decoding the spoken utterance into a word sequence), a natural language translator (for converting a word sequence into a sequence of signs belonging to the sign language), and a 3D avatar animation module (for playing back the signs). For the natural language translator, three technological approaches have been implemented and evaluated: an example-based strategy, a rule-based translation method and a statistical translator. For the final version, the implemented language translator combines all the alternatives into a hierarchical structure. This paper includes a detailed description of the field evaluation. This evaluation was carried out in the Local Traffic Office in Toledo involving real government employees and Deaf people. The evaluation includes objective measurements from the system and subjective information from questionnaires. The paper details the main problems found and a discussion on how to solve them (some of them specific for LSE).

Deployment and validation of a smart system for screening of language disorders in primary care

Neuro-evolutive development from birth until the age of six years is a decisive factor in a child?s quality of life. Early detection of development disorders in early childhood can facilitate necessary diagnosis and/or treatment. Primary-care pediatricians play a key role in its detection as they can undertake the preventive and therapeutic actions requested to promote a child?s optimal development. However, the lack of time and little specific knowledge at primary-care avoid to applying continuous early-detection anomalies procedures. This research paper focuses on the deployment and evaluation of a smart system that enhances the screening of language disorders in primary care. Pediatricians get support to proceed with early referral of language disorders. The proposed model provides them with a decision-support tool for referral actions to trigger essential diagnostic and/or therapeutic actions for a comprehensive individual development. The research was conducted by starting from a sample of 60 cases of children with language disorders. Validation was carried out through two complementary steps: first, by including a team of seven experts from the fields of neonatology, pediatrics, neurology and language therapy, and, second, through the evaluation of 21 more previously diagnosed cases. The results obtained show that therapist positively accepted the system proposal in 18 cases (86%) and suggested system redesign for single referral to a speech therapist in three remaining cases.

Desarrollo de aplicaciones basadas en Linux Embedded en una arquitectura basada en Cyclone V SoC (System on Chip) de Altera

We attempt to integrate and start up the set of necessary tools to deploy the design cycle of embedded systems based on Embedded Linux on a "Cyclone V SoC" made by Altera. First, we will analyze the available tools for designing the hardware system of the SoCkit development kit, made by Arrow, which has a "Cyclone V SoC" system (based on a "ARM Cortex-A9 MP Core" architecture). When designing the SoCkit board hardware, we will create a new peripheral to integrate it into the hardware system, so it can be used as any other existent resource of the SoCkit board previously configured. Next, we will analyze the tools to generate an Embedded Linux distribution adapted to the SoCkit board. In order to generate the Linux distribution we will use, on the one hand, a software package from Yocto recommended by Altera; on the other hand, the programs and tools of Altera, Embedded Development Suite. We will integrate all the components needed to build the Embedded Linux distribution, creating a complete and functional system which can be used for developing software applications. Finally, we will study the programs for developing and debugging applications in C or C++ language that will be executed in this hardware platform, then we will program a Linux application as an example to illustrate the use of SoCkit board resources.

Methodology for developing an advanced communications system for the Deaf in a new domain

A methodology for developing an advanced communications system for the Deaf in a new domain is presented in this paper. This methodology is a user-centred design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. During the requirement analysis, both the user and technical requirements are evaluated and defined. For generating the parallel corpus, it is necessary to collect Spanish sentences in the new domain and translate them into LSE (Lengua de Signos Española: Spanish Sign Language). LSE is represented by glosses and using video recordings. This corpus is used for training the two main modules of the advanced communications system to the new domain: the spoken Spanish into the LSE translation module and the Spanish generation from the LSE module. The main aspects to be generated are the vocabularies for both languages (Spanish words and signs), and the knowledge for translating in both directions. Finally, the field evaluation is carried out with deaf people using the advanced communications system to interact with hearing people in several scenarios. In this evaluation, the paper proposes several objective and subjective measurements for evaluating the performance. In this paper, the new considered domain is about dialogues in a hotel reception. Using this methodology, the system was developed in several months, obtaining very good performance: good translation rates (10% Sign Error Rate) with small processing times, allowing face-to-face dialogues.

Desing and Validation of a Light Inference System to Support Embedded Context Reasoning

Embedded context management in resource-constrained devices (e.g. mobile phones, autonomous sensors or smart objects) imposes special requirements in terms of lightness for data modelling and reasoning. In this paper, we explore the state-of-the-art on data representation and reasoning tools for embedded mobile reasoning and propose a light inference system (LIS) aiming at simplifying embedded inference processes offering a set of functionalities to avoid redundancy in context management operations. The system is part of a service-oriented mobile software framework, conceived to facilitate the creation of context-aware applications—it decouples sensor data acquisition and context processing from the application logic. LIS, composed of several modules, encapsulates existing lightweight tools for ontology data management and rule-based reasoning, and it is ready to run on Java-enabled handheld devices. Data management and reasoning processes are designed to handle a general ontology that enables communication among framework components. Both the applications running on top of the framework and the framework components themselves can configure the rule and query sets in order to retrieve the information they need from LIS. In order to test LIS features in a real application scenario, an ‘Activity Monitor’ has been designed and implemented: a personal health-persuasive application that provides feedback on the user’s lifestyle, combining data from physical and virtual sensors. In this case of use, LIS is used to timely evaluate the user’s activity level, to decide on the convenience of triggering notifications and to determine the best interface or channel to deliver these context-aware alerts.d

A new way of teaching different subjects in a foreign language in the Building Engineering Degree at the Universidad Politécnica.

The European Union has been promoting linguistic diversity for many years as one of its main educational goals. This is an element that facilitates student mobility and student exchanges between different universities and countries and enriches the education of young undergraduates. In particular, a higher degree of competence in the English language is becoming essential for engineers, architects and researchers in general, as English has become the lingua franca that opens up horizons to internationalisation and the transfer of knowledge in today’s world. Many experts point to the Integrated Approach to Contents and Foreign Languages System as being an option that has certain benefits over the traditional method of teaching a second language that is exclusively based on specific subjects. This system advocates teaching the different subjects in the syllabus in a language other than one’s mother tongue, without prioritising knowledge of the language over the subject. This was the idea that in the 2009/10 academic year gave rise to the Second Language Integration Programme (SLI Programme) at the Escuela Arquitectura Técnica in the Universidad Politécnica Madrid (EUATM-UPM), just at the beginning of the tuition of the new Building Engineering Degree, which had been adapted to the European Higher Education Area (EHEA) model. This programme is an interdisciplinary initiative for the set of subjects taught during the semester and is coordinated through the Assistant Director Office for Educational Innovation. The SLI Programme has a dual goal; to familiarise students with the specific English terminology of the subject being taught, and at the same time improve their communication skills in English. A total of thirty lecturers are taking part in the teaching of eleven first year subjects and twelve in the second year, with around 120 students who have voluntarily enrolled in a special group in each semester. During the 2010/2011 academic year the degree of acceptance and the results of the SLI Programme have been monitored. Tools have been designed to aid interdisciplinary coordination and to analyse satisfaction, such as coordination records and surveys. The results currently available refer to the first and second year and are divided into specific aspects of the different subjects involved and into general aspects of the ongoing experience.
