Diffusional kurtosis imaging using a fast heuristic constrained linear least squares algorithm: a plugin for OsiriX

Diffusion Kurtosis Imaging (DKI) is a fairly new magnetic resonance imag-ing (MRI) technique that tackles the non-gaussian motion of water in biological tissues by taking into account the restrictions imposed by tissue microstructure, which are not considered in Diffusion Tensor Imaging (DTI), where the water diffusion is considered purely gaussian. As a result DKI provides more accurate information on biological structures and is able to detect important abnormalities which are not visible in standard DTI analysis. This work regards the development of a tool for DKI computation to be implemented as an OsiriX plugin. Thus, as OsiriX runs under Mac OS X, the pro-gram is written in Objective-C and also makes use of Apple’s Cocoa framework. The whole program is developed in the Xcode integrated development environ-ment (IDE). The plugin implements a fast heuristic constrained linear least squares al-gorithm (CLLS-H) for estimating the diffusion and kurtosis tensors, and offers the user the possibility to choose which maps are to be generated for not only standard DTI quantities such as Mean Diffusion (MD), Radial Diffusion (RD), Axial Diffusion (AD) and Fractional Anisotropy (FA), but also DKI metrics, Mean Kurtosis (MK), Radial Kurtosis (RK) and Axial Kurtosis (AK).The plugin was subjected to both a qualitative and a semi-quantitative analysis which yielded convincing results. A more accurate validation pro-cess is still being developed, after which, and with some few minor adjust-ments the plugin shall become a valid option for DKI computation

The BioDICE Taverna plugin for clustering and visualization of biological data: a workflow for molecular compounds exploration

Background: In many experimental pipelines, clustering of multidimensional biological datasets is used to detect hidden structures in unlabelled input data. Taverna is a popular workflow management system that is used to design and execute scientific workflows and aid in silico experimentation. The availability of fast unsupervised methods for clustering and visualization in the Taverna platform is important to support a data-driven scientific discovery in complex and explorative bioinformatics applications. Results: This work presents a Taverna plugin, the Biological Data Interactive Clustering Explorer (BioDICE), that performs clustering of high-dimensional biological data and provides a nonlinear, topology preserving projection for the visualization of the input data and their similarities. The core algorithm in the BioDICE plugin is Fast Learning Self Organizing Map (FLSOM), which is an improved variant of the Self Organizing Map (SOM) algorithm. The plugin generates an interactive 2D map that allows the visual exploration of multidimensional data and the identification of groups of similar objects. The effectiveness of the plugin is demonstrated on a case study related to chemical compounds. Conclusions: The number and variety of available tools and its extensibility have made Taverna a popular choice for the development of scientific data workflows. This work presents a novel plugin, BioDICE, which adds a data-driven knowledge discovery component to Taverna. BioDICE provides an effective and powerful clustering tool, which can be adopted for the explorative analysis of biological datasets.

Unity assessment: desarrollo de un plugin de Unity evaluación basada en juegos y desarrollo de un juego de artes escénicas

En el ámbito educativo, gran parte de los docentes realizan la evaluación de alumnos mediante herramientas tradicionales: exámenes, cuestionario, trabajos, etc. Esta forma de evaluar presenta inconvenientes, por un lado, precisa que el profesor esté durante todo el proceso de evaluación y, por otro lado, exige tiempo y trabajo desmesurado. Por ello, en este proyecto nos dedicamos a crear una forma de evaluar diferente. Esta forma de evaluar consistirá, por un lado, en obtener información cuantitativa sobre cuánto ha aprendido el alumno a través de una puntuación. Este tipo de evaluación, se realizará mediante un videojuego. Por otro lado, consistirá en almacenar esta puntuación en algún sitio de acceso fácil y rápido para el profesor. Para este cometido hemos elegido una plataforma virtual, Moodle. Elegimos Moodle porque es una plataforma diseñada para ayudar a los profesores en su labor. Pueden gestionar sus asignaturas e interactuar con sus alumnos. El profesor crea un entorno centrado en el alumno que le ayuda a cimentar conocimientos según sus habilidades. Hemos elegido los videojuegos porque son una herramienta de enseñanza efectiva. Ofrecen una gran mejora en el rendimiento académico del alumno, así como potenciar la adquisición de conocimientos o incluso aumentar la motivación y el interés del jugador sobre el contenido del videojuego. Por tanto, en este proyecto también nos centraremos en crear un videojuego. Crearemos un videojuego orientado al teatro para fomentar el interés y la motivación de los jugadores en este campo. El videojuego estará basado en la obra de teatro llamada El Alcalde de Zalamea del autor Calderón de la Barca. Por último, para enviar la puntuación obtenida a Moodle desde el videojuego es necesario crear una comunicación entre estas dos tecnologías. Nuestro objetivo primordial en este proyecto es crear dos aplicaciones. Una en el videojuego que es la encargada de enviar la puntuación. Y otra en Moodle, encargada de almacenar la puntuación en la base de datos y mostrarla al profesor, de una forma intuitiva.

Integração modular em visualizadores médicos e aposição da marcação CE do Dispositivo Médico

Neste documento ´e feita a descrição detalhada da integração modular de um script no software OsiriX. O objectivo deste script ´e determinar o diâmetro central da artéria aorta a partir de uma Tomografia Computorizada. Para tal são abordados conceitos relacionados com a temática do processamento de imagem digital, tecnologias associadas, e.g., a norma DICOM e desenvolvimento de software. Como estudo preliminar, são analisados diversos visualizadores de imagens médica, utilizados para investigação ou mesmo comercializados. Foram realizadas duas implementações distintas do plugin. A primeira versão do plugin faz a invocação do script de processamento usando o ficheiro de estudo armazenado em disco; a segunda versão faz a passagem de dados através de um bloco de memória partilhada e utiliza o framework Java Native Interface. Por fim, é demonstrado todo o processo de aposição da Marcação CE de um dispositivo médico de classe IIa e obtenção da declaração de conformidade por parte de um Organismo Notificado. Utilizaram-se os Sistemas Operativos Mac OS X e Linux e as linguagens de programação Java, Objective-C e Python.

De touch: extending service channels in an airport through touch technologies

This project aimed to create a communication and interaction channel between Madeira Airport and its passengers. We used the pre-existent touch enabled screens at the terminal since their potential was not being utilised to their full capacity. To achieve our goal, we have followed an agile strategy to create a testable prototype and take advantages of its results. The developed prototype is based on a plugin architecture turning it into a maintainable and highly customisable system. The collected usage data suggests that we have achieved the initially defined goals. There is no doubt that this new interaction channel is an improvement regarding the provided services and, supported by the usage data, there is an opportunity to explore additional developments to the channel.

Integration of repositories in elearning systems

The wide acceptance of digital repositories today in the eLearning field raises several interoperability issues. In this paper we present the interoperability features of a service oriented repository of learning objects called crimsonHex. These features are compliant with the existing standards and we propose extensions to the IMS interoperability recommendation, adding new functions, formalizing message interchange and providing also a REST interface. To validate the proposed extensions and its implementation in crimsonHex we developed a repository plugin for Moodle 2.0 that is expected to be included in the next release of this popular learning management system.
