RESUMEN: Este proyecto consiste en el análisis, diseño y desarrollo de una herramienta de apoyo para la autoevaluación de tareas de Moodle mediante el uso de los WebServices que proporciona la propia plataforma. El objetivo es conseguir facilitar el proceso de autoevaluación de prácticas de programación para dos casos de uso concretos, tanto para prácticas de evaluación única (exámenes) como para prácticas de evaluación interactiva (prácticas de aula). Mediante el uso de una librería previamente estudiada llamada moodleteacher, la cual hace uso de los WebServices, se va a construir una librería de utilidades que recoge diferentes funcionalidades específicas en cuanto al proceso general de autoevaluar tareas de Moodle. Esta serie de funcionalidades que abarca la librería que se va a implementar, servirá de apoyo para la construcción de las dos herramientas principales que se van a construir, para cubrir los dos casos de uso de evaluación (única o interactiva). ABSTRACT: This project consists of the analysis, design and development of a support tool for the self-assessment of Moodle tasks through the use of WebServices provided by the platform itself. The objective is to facilitate the self-assessment process of programming practices for two specific use cases, both for single assessment practices (exams) and for interactive assessment practices (classroom practices). Through the use of a previously studied library called moodleteacher, which makes use of WebServices, a library of utilities will be built and it includes different specific functionalities regarding the general process of self-assessing Moodle tasks. This series of functionalities that includes the library that is going to be implemented, will support the construction of the two main tools that are going to be built, to cover the two evaluation use cases (single or interactive).

Several initiatives aim to map the diversity of Natural History (NH) collections and standardise their descriptions. The Global Registry of Biodiversity Repositories (GRBio) is the most recent global registry. Unfortunately the server has been down since mid-2018 but the Global Biodiversity Information Facility (GBIF) recently "rescued" this data. In addition to this, the One World Collection exercise is a set of high-level collection descriptors (size, group coverage and geographic distribution) supporting a common strategy between the largest world institutions. Despite these efforts, a large part of the NH collections remains digitally unavailable and digitisation at the specimen level will take several decades. A new NH collections dashboard is needed in order to harmonise the efforts of the institutions. The Consortium of European Taxonomic Facilities (CETAF) is a good place to introduce this excercise. CETAF’s members hold over half of the world’s NH collections, representing 80% of the world's bio- and geo-diversity. Most of these collections are now engaged in the preparation for the common process of the Distributed System of Scientific Collections (DiSSCo, European Strategy Forum on Research Infrastructure). Additionally in Belgium, the Royal Belgian Institute of Natural Sciences (RBINS), Royal Museum of Central Africa (RMCA), Meise Botanic Garden (MBG) and CETAF have joined efforts to set up a common research portal (Natural Heritage, BRAIN-be project). The goal is to link together several collection management systems (CMS) and to (re)create links between isolated collection items. The CETAF collections dashboard splits the information into small metadata units related to topics relevant to the collections (taxonomy, geographic distribution, digitisation strategy and coverage, stratigraphy, etc.). The model allows for the creation of new units without a complete modification of the database structure. All units are defined by the Dublin Core and by fields derived from the Innovation and consolidation for large scale digitisation of natural heritage (ICEDIG) d2.3 deliverable (van Egmond et al. 2019). The object hierarchy allows for the creation of sub-collections and preserves the unity of the information. The CMS has an internal object database with a full index and a faceted search interface. It also has web services and XLS (Microsoft® Excel®) import/export functionalities. The collection dashboard also includes a complete workflow and access rights management at the object level. This is important for the information that is protected by the EU General Data Protection Regulation (GDPR). The dashboard is now being evaluated with the collections hosted by the partners of Natural Heritage. The system will be proposed to CETAF members and connections will be established with the international portals such as the GBIF or the future DiSSCo portal.

The Internet of Things (IoT) is the recent way to join low-cost hardware and cloud computing, in order to manage a network of physical devices and their data collection. During the last years the number of devices connected to IoT is dramatically increased, as well as, the number of webservices which allow to collect and manage the data. Most of these services are free for personal use, and low-cost for commercial purposes. In this work, the IoT technology was employed to monitor the health status of maritime signals, such as buoys, seamarks, beacons, etc. The developed system allows to react swiftly and efficiently if a problem occurs, in order to preserve both the safety of navigation and the signals integrity. Furthermore, the developed hardware equipment is low-cost as well as the webservices employed to notify possible problems. The system was, initially, developed to follow the position of a buoy using a GNSS device for this reason, even now, the system name is "Buoy Monitoring System" (BMS). Specifically, the paper describes the system design, its realization and the results obtained in terms of reliability; the case study regards all light maritime signals that operate in the Taranto harbor.

Industrial systems are composed of several sub systems and architectures that are provided by different manufacturers. System integration aims at enabling a developer to combine these unit systems with limited functionality into one system that can accomplish the execution of required process. Modern integrated systems are developed on top of service-oriented architecture and use webservices for information exchange. Such systems are swiftly deployable and ensure platform interoperability, system adaptability and service reusability. Meanwhile, system integration tests help to reduce the complexity during the integration phase thus ensuring process uniformity. This thesis focuses on deploying a robotic manipulator in an industrial cell. The robot is in-stalled in the assembly line as service provider while services are invoked by using RESTful web services. Second objective of the thesis is to implement a free shape path planning algorithm for the deployed autonomous manipulator to follow the desired curve. The last component of this thesis is focused on developing integration tests to examine and verify the designed system. The robot was commissioned at the FASTory assembly line, installed at FAST lab of Tampere University. The free shape paths were implemented by interpolating Bezier curves using De Casteljau algorithm. System was successfully integrated and verified using Top-down depth first and bottom-up breadth first integration testing approaches.

DaRWIN (Data Research Warehouse Information Network) is an in-house solution developed by the Royal Belgian Institute of Natural Sciences (RBINS), as a Natural History collections management system for biological and geological samples in collections. In 2014, the Royal Museum for Central Africa (RMCA) adopted this system for its collections and started to take part in new developments. The DaRWIN database currently manages information on more than 600,000 records (about 4 million specimens) housed at the RBINS and more than 650,000 records (more than 1 million specimens) at the RMCA. DaRWIN is an open source system, consisting of a PostgreSQL database and a customizable web-interface based on the Symfony framework (https://symfony.com). DaRWIN is divided into 2 parts: one public section that gives a “read-only” access to digitised specimens, one section for registered users, with different levels of access rights (user, encoder, conservator and administrator), customizable for each collection and allowing update of specimens and collections, daily management of collections, and the potential for dealing with sensitive information. one public section that gives a “read-only” access to digitised specimens, one section for registered users, with different levels of access rights (user, encoder, conservator and administrator), customizable for each collection and allowing update of specimens and collections, daily management of collections, and the potential for dealing with sensitive information. DaRWIN stores sample data and related information such as place and date of collection, missions and collectors, identifiers, technicians involved, taxonomy, identification information (type, stage, state, etc.), bibliography, related files, storage, etc. Other features that deal with day-to-day curation operations are available: loans, printing of labels for storage, statistics and reporting. DaRWIN features its own JSON (JavaScript Object Notation) webservice for specimens and scientific names and can export data in tab-delimited, Excel, PDF and GeoJSON formats. More recently, a procedure for importing batches of data has been developed, based on tab-delimited files, making integration of data from (old/historical) databases faster and more controlled. Additional improvements of the user interface and database model have been made. For example, parallel taxonomical hierarchies can be created, allowing users to work with temporary taxonomies, old scientific names (basionyms and synonyms) and document the history of type specimens. Finally, quality control and data cleaning on several tables have been implemented, e.g. mapping of locality names with vocabularies like Geonames, adding ISO 3166 two-letter country codes (https://www.iso.org/iso-3166-country-codes.html), cleaning duplicates from people/institutions and taxonomy catalogues. A tool for checking taxonomical names on GBIF (Global Biodiversity Information Facility), WoRMS (World Register of Marine Species) and DaRWIN itself, based on webservices and tab-delimited files, has been developed. Last year, RBINS, RMCA and Meise Botanic Garden (MBG) defined a new framework of collaboration in the NaturalHeritage project (http://www.naturalheritage.be), in order to foster interoperability among their collection data sources. This new framework presents itself as one common research portal for data on natural history collections (from DaRWIN and other existing collection databases) of the three partnered institutions and makes data compliant to a standard agreed by the partners. See Poster "NaturalHeritage: Bridging Belgian Natural History Collections" for more information. DaRWIN is accessible online (http://darwin.naturalsciences.be). A Github repository is also available (https://github.com/naturalsciences/natural_heritage_darwin).

There are devices performing various function s and providing services to other devices. These devices provide output in various formats like xml,html,csv,pdf etc. It becomes difficult to parse this data into required format as it requires extra overhead.To send th is data we are considering two options namely SOAP services or RESTful Services. RESTful services are replacing SOAP services because of their various advantages described further in this paper,So to provide the interoperability between devices we sugges t to use RESTful webservices s using json as output . REST is an architectural style to develop webservices which represent each device with an unique URI.We will discuss as to how we can use OAuth as a security mechanism for these webservices and how effectiv e it is to use with Io T devices.We provide general guidel ines on how to design a REST API (Application programming interface) device description for machine - to - mac hine interactions. We will be discussing about the pull approach where only client can initiate communication and a push approach where a server can also start an interaction with client based on the triggers defined which in our case is a voice command and how s all these fit in to define a complete communi cation approach. https://www.ijiert.org/paper-details?paper_id=141293

Service-oriented architectures are more popular than ever, and increasingly companies and organizations depend on services offered through Web APIs. The capabilities and complexity of Web APIs differ from service to service, and therefore the impact of API errors varies. API problem cases related to Adyen's payment service were found to have direct considerable impact on API consumer applications. With more than 60,000 daily API errors, the potential impact is enormous. In an effort to reduce the impact of API related problems, we analyze 2.43 million API error responses to identify the underlying faults. We quantify the occurrence of faults in terms of the frequency and impacted API consumers. We also challenge our quantitative results by means of a survey with 40 API consumers. Our results show that 1) faults in API integration can be grouped into 11 general causes: invalid user input, missing user input, expired request data, invalid request data, missing request data, insufficient permissions, double processing, configuration, missing server data, internal and third party, 2) most faults can be attributed to the invalid or missing request data, and most API consumers seem to be impacted by faults caused by invalid request data and third party integration; and 3) insufficient guidance on certain aspects of the integration and on how to recover from errors is an important challenge to developers.

‘But I don’t know how to work with [name of tool or resource]’ is something one often hears when researchers in Human and Social Sciences (HSS) are confronted with language technology, be it written or spoken, tools or resources. The TTNWW project shows that these researchers do not need to be experts in language or speech technology, or to know all kinds of details about the tools involved. In principle they only need to make clear what they want to achieve. In this chapter we describe a series of tools that are already available as a webservice. Details are not presented — interested readers are referred to the papers mentioned in the References and to the TTNWW website.

Mit steigendem Grad der Technisierung und voranschreitenden Entwicklungen im Gebiet der Industrie 4.0 wird das Erfassen und Verwalten von Daten ein immer gr����e-rer Aufgabenbereich. Ein Teilgebiet davon ist das Management von Daten, die zum Testen und ��berwachen von Maschinen n��tig sind. F��r deren Einf��hrung wird meist gro��es Fachwissen im Bereich der Informationstech-nik ben��tigt. Wenn in einem Betrieb kein Informatiker vorhanden ist, muss entweder einer von au��en hinzugezogen werden oder jemand aus einem anderen Fachbereich muss sich, eventuell von Grund auf, mit diesem Thema auseinandersetzen. In dieser Arbeit soll ein System geschaffen werden, das hilft dieses Problem besser zu bew��ltigen. Auch Nutzer mit geringem Informationstechnikwissen sollen die M��glich-keit haben, ein individuelles Datenerfassungssystem zu implementieren. Ein wichtiger Punkt ist dabei die einfache und ��bersichtliche Gestaltung. Dazu wird in dieser Arbeit ein Webservice, genauer ein Representational State Trans-fer (REST) Application Programming Interface (API), geschaffen. Diese API ist gut ska-lierbar. Auch nachdem sie beispielsweise f��r Testzwecke implementiert wurde, kann sie in ein laufendes System eines Betriebs eingef��gt werden. Neben dem Speichern und Verwalten von Daten in einer MySQL-Datenbank erm��glicht sie die Steuerung von Sensorsystemen. Die API kann die gewonnenen Daten in einem Netzwerk bereit-stellen und verf��gt ��ber einen Authentifikationsmechanismus sowie Rollen- und Rechtevergabe, um diese Daten anschlie��end zu sch��tzen. Im ersten Teil der Arbeit geht es um die grundlegende Theorie und die Prozesse der Entscheidungsfindung zugunsten bestimmter Komponenten. Im zweiten Teil wird zu-n��chst der Aufbau der API erkl��rt. Danach wird die Handhabe der Anwendung erl��u-tert. Es folgt die Beschreibung einer konkreten Verwendungsm��glichkeit: Das Kon-zept beinhaltet die Installation der API auf einem g��nstigen Einplatinencomputer (Raspberry Pi), mit dessen Hilfe gezeigt wird, wie die API Sensoren steuern und die ausgelesenen Daten verwalten kann. Ergebnis ist ein Leitfaden zur schnellen, g��nstigen und einfachen Anwendung der API. Das vorgestellte System erm��glicht die rasche Erfassung und Verwaltung von Daten in Testf��llen, hohe Skalierbarkeit, dauerhaften Betrieb und Anbindung an be-stehende Systeme. Die Implementierung ist so gestaltet, dass sie auch ein unerfahre-ner Nutzer durchf��hren kann., With the increasing degree of technization and the development in sectors like Indus-try 4.0, the collection and maintenance of data is becoming an increasingly important task. Part of this is the management of data that is needed to test and monitor ma-chines. The implantation of such a data management system requires a great deal of knowledge in the field of information technology. In mechanical engineering opera-tions, however, there is often no one with the appropriate knowledge. Then a com-puter scientist has to be drawn from the outside or someone from another field has to acquire the abilities needed for this work, which can take quite some time. In this thesis, a system will be created that helps to accomplish this task by allowing the user to implement an individual data acquisition system with little information technology knowledge. An important point is the simple and clear design. A web service, more precisely a Representational State Transfer (REST) Application Programming Interface (API), is created to deal with this problem. This API is not only scalable, but also easy to be implemented into an existing system after using it for test purposes. In addition to storing and managing data in a database, it enables also the control of sensor systems used for data collection. The API can provide the data in a network and has an authentication mechanism as well as roles for users to secure data. The first part of the work deals with the basic theory and the processes of decision-making in favor of using certain components over others. The second part explains the structure of the API. Then the handling of the application itself is shown. A de-scription of a specific usage of the API follows: The concept involves installing the API on a low-cost single-board computer (Raspberry Pi), showing how the API can control sensors and manage the so gathered data. Thus a concept for a fast, inexpensive and simple application can be presented. It enables to quickly capture and manage data in test cases, supports high scalability, permanent operation and connection to existing systems. The implementation is de-signed in such a way that it can also be carried out by an inexperienced user.

La investigación desarrollada en el presente trabajo de grado presenta una propuesta de arquitectura para la identificación personal por medio de un token de seguridad, a través de dispositivos móviles y haciendo uso de sistemas de gobernanza y sensores de proximidad para generar la firma digital o token correspondiente, con el fin de acceder a los servicios web de instituciones (públicas o privadas) de una manera transparente y segura. La propuesta de arquitectura presentada consta de diversos elementos físicos que se encuentran separados geográficamente. La arquitectura, hace uso de varios sistemas que interactúan entre sí a través de servicios web y sistemas NFC, permitiendo de esta manera que cualquier Entidad (pública o privada) pueda registrarse y registrar los servicios que desea ofrecer a sus usuarios con la tranquilidad de que ellos podrán hacer uso de toda una infraestructura (aplicaciones, sistemas de gobernanza) que les permitirá de una manera casi automática y por su puesto segura, identificarse en el consumo de los servicios ofrecidos. Es importante aclarar que para que la arquitectura se pueda aplicar es necesario que las Entidades subscritas habiliten un adaptador en donde expondrán sus servicios de identificación e implementaran las funcionalidades de recibir las firmas generadas, validarlas utilizando un servicio web propio del sistema e identificarlas para conectar de una manera transparente al usuario con los servicios ofrecidos. Las características de este adaptador y los subprocesos que debe tener en cuenta son descritos y explicados en las memorias del presente trabajo de grado. Para validar la arquitectura propuesta, se diseñó y desarrolló una aplicación para Dispositivos Android que implementa el token de seguridad generado para consumir servicios de una Entidad Educativa y un servicio Web utilizado por la Entidad Educativa con la funcionalidad de validar los tokens y capacidad de identificar el dispositivo y los usuarios que están consumiendo sus servicios, el proceso de validación se describe ampliamente en las memorias del presente trabajo de grado Contenido iii 1 INTRODUCCIÓN 1 2 REVISION BIBLIOGRÁFICA 2 2.1 Plataforma para el acceso a servicios desde dispositivos móviles utilizando parámetros de autenticación basados en SIM Card 2 2.2 Ecosistema para la Creación de Firma Digital Avanzada en Movilidad y Autenticación Mediante Elemento Seguro 3 2.3 Análisis De Un Servicio Bancario Móvil Seguro Utilizando Una Aplicación Instalada En La Tarjeta Sim 3 3 MARCO TEÓRICO 5 3.1 Arquitectura orientada a servicios 5 3.2 Web Services 6 3.3 SOAP 6 3.4 Firma digital 7 3.5 Android 7 3.6 NFC 9 3.7 POO 9 3.8 Php 10 3.9 HTML 11 3.10 Apache 11 3.11 Patrón de diseño Modelo-Vista-Controlador (MVC) 12 3.12 UML 13 3.13 Frameworks 14 3.13.1 Zend Framework 14 3.14 IDE's 15 3.14.1 Netbeans 15 3.15 PostgreSQL 16 3.16 Ajax 16 3.17 Jquery 17 3.18 MD5 18 3.19 JSON 18 4 OBJETIVOS 20 4.1 Objetivo general 20 4.2 Objetivos específicos 20 5 METODOLOGÍA 21 5.1 ACTIVIDADES 21 5.1.1 Ambientación del espacio problema 21 5.1.2 Realización del estudio de Caracterización de Componentes de la Arquitectura 21 5.1.3 Diseño del modelo de arquitectura 22 5.1.4 Formalización y Especificación de Casos de Uso 22 5.1.5 Análisis de requisitos de los Sistemas 22 5.1.6 Análisis y requisitos de Software 22 5.1.7 Diseño detallado 22 5.1.8 Desarrollo de Aplicaciones 23 5.1.9 Verificación del modelo 23 5.1.10 Generación de Documento de Tesis 23 6 RESULTADOS DE LA INVESTIGACIÓN 24 6.1 DEFINICIÓN DEL PROCESO 24 6.1.1 Registro de la Entidad 24 6.1.2 Generación del token en el dispositivo del usuario 27 6.1.3 Consumo de los servicios a través del dispositivo 28 6.2 ARQUITECTURA PROPUESTA 31 6.2.1 Características de la solución 31 6.2.2 Diagrama 32 6.2.3 Elementos 33 6.3 SISTEMA DE INFORMACIÓN PARA GOBIERNO EN LINEA – SIGEL 37 6.3.1 SIGEL BD 37 6.3.2 SIGEL WEB 40 6.3.3 Servicios Web 46 6.3.4 SIGEL APP – Android 51 6.3.5 ADMSIGEL NFC 59 6.4 VALIDACIÓN ARQUITECTURA 64 6.4.1 Registro en el SIGEL WEB 65 6.4.2 Generación del Token 72 6.4.3 Consumo Servicio de Logueo 78 7 CONCLUSIONES 83 8 RECOMENDACIONES Y TRABAJOS FUTUROS 84 9 BIBLIOGRAFÍA Y REFERENCIAS 85 Maestría The research developed in this paper has a proposed architecture for personal identification through a security token, through mobile devices and using governance systems and proximity sensors to generate the digital signature or corresponding token in order to access the web services (public or private) institutions in a transparent and secure manner. The proposed architecture has various physical elements that are separated geographically. The architecture uses multiple systems interacting through web services and NFC systems, allowing any entity (public or private) register and register the services you want to provide users, with the assurance that they can use an infrastructure (applications, systems of governance) that it will allow an almost automatic and safe way, identify them in consumption of services offered It is important to clarify that the architecture only can be applied if the entities subscribed, enable an adapter where exposes their identification services and implements the functionalities of receiving the generated signatures and validate it using a proprietary web service system to connect and identify transparently the user with the services offered. The characteristics of this adapter and the sub process that should be considered are described and explained in the memories of this degree work. To validate the proposed architecture, was designed and developed an application for Android devices that implements the security token generated for consume services of an educational institution and a Web service used by the educational institution with the functionality to validate the tokens and ability to identify the device and users who are consuming services, the validation process is widely described in the memoirs of this paper

A presente dissertação descreve o desenvolvimento de um sistema de pagamentos eletrónicos direcionado para serviços municipais. Este sistema está dividido em três áreas principais: a administração ou backoffice, os portais web ou frontend e as integrações com plataformas de terceiros. Relativamente à administração do sistema foram desenvolvidas funcionalidades em PowerBuilder, com o objetivo de monitorizar, configurar e gerir todos os pagamentos efetuados pelos munícipes. Os portais web representam a interface do sistema com o utilizador, foram desenvolvidos em Java, JavaScript, Asp e Html, e disponibilizam todos os serviços prestados pelas câmaras municipais, permitindo a consulta, emissão e pagamento através de balcão de atendimento ou serviços online: cartão de crédito, referências multibanco e pagamento presencial são as modalidades de pagamento implementadas. Opcionalmente, é também possível a integração com plataformas de terceiros o que vem aumentar o número de alternativas de pagamento. Estas integrações são realizadas através de serviços web prezando sempre a segurança, integridade e confidencialidade dos dados. O sistema de pagamentos eletrónicos veio oferecer aos munícipes uma maior comodidade e rapidez na emissão e liquidação de taxas e licenças, permitiu reduzir os custos de atendimento, a alocação de recursos humanos e realizar a desmaterialização de documentos, contribuindo assim para a modernização da administração pública. Explicam-se também as opções tomadas na implementação do projeto, as tecnologias envolvidas no tipo de pagamentos implementados e a metodologia utilizada para o desenvolvimento. Em termos de segurança foram implementados vários mecanismos com o objetivo de proteger transações e dados. Foram realizados testes de caixa branca, preta e de segurança. O sistema encontra-se na primeira versão, mas já em operação, como parte da aplicação financeira e acessível em portais web.

International audience; Telemedicine allows collaborative activities between health professionals for the deployment of medical procedures carried out remotely by means of device using information and communication technologies. This article focuses on the Teleexpertise that allows collaboration between medical professionals in order to share knowledge and expert advices used as explanation elements for decision support. We propose a conceptual model integrating the FIPA (Foundation for Intelligent Physical Agents) Contract Net Protocol which permits to collect medical professionals' answers for a request for teleexpertise in an efficient manner. Our model satisfies four requirements (coverage, QoS (Quality of Service) guarantees and prioritisation, mobility and roaming, service usability) on the configuration and operation of the underlying network and the services. Therefore, we provide an operational assistance by improvement of the networks quality of service via interoperable web services. Finally, we hope to bring a tangible contribution on the implementation of this suggested conceptualization that will allow to generate relevant and action-oriented findings
