A strategy for a new type of platform for chemoinformatics software development and its first implementation are presented. The basic task of such a platform is to apply sequences of computational methods to high numbers of molecules. The implementation presented is based on four major components: (a) the application manager, responsible for running programs and for data management, (b) executable applications that supply limited pieces of functionality, (c) syntax definitions for data and control files and (d) the runtime library which comprises routines for data handling and user interface. This simple concept is implemented in the software package marvin. Different computational methods are available within marvin, including parts of commercial software packages (e.g. molecular modeling, bioinformatics, statistics, etc.) as well as newly developed and innovative algorithms. The basic layout of marvin is described and a simple example illustrates its application.

Mathematical models, designated to simulate complex physical processes, are often used in scientific and engineering studies. In nuclear applications, these models, integrated in computation codes, are very complex and very high consuming CPU time. We present the “Uncertainty and Sensitivity” platform Uranie developed by the CEA to perform Uncertainty Quantification, Verification and Validation codes, and Sensitivity Analysis. Uranie was used in several nuclear studies like performance assessment with ANDRA, with neutronics and thermal-hydraulics codes, nuclear fuel thermal behaviour.

Software engineering methodologies rely on various and complex graphical representations and are more useful when associated to CASE (Computer Aided Software Engineering) tools designed to take care of constraints that have to be respected. Now, CASE tools gave way to CASE environments (a set of tools that have a strong coherence in their us). This concept provides enhanced solutions for software reusability while the environment may be adapted to a specific understanding of a design methodology.This paper describes FrameKit, an Ada based framework dedicated to the quick implementation of CASE environments. We summarize first the concepts implemented in FrameKit and illustrate them using a detailed example of a simple tool implementation and integration.; Les méthodes de Génie Logiciel actuelles, basées sur des représentations graphiques complexes, ne sont réellement opérationnelles que si elles sont supportées par des Ateliers de Génie Logiciel. Ces outils prennent en charge les contraintes d'une méthode. On parle désormais d'environnement CASE: c'est à dire un ensemble d'outils possédant sa propre cohérence et mettant en .uvre des solutions élaborées. l'apport principal d'un tel concept est l'adaptabilité des environnements concernés.Cet article présente FrameKit, une plate-forme réalisée en Ada et dédiée à l'implémentation rapide (prototypage) d'environnements CASE. Nous y résumons les concepts implémentés et les illustrons à l'aide d'un exemple d'outil dont nous détaillons la réalisation et l'intégration.

International audience; In this paper, we have presented FrameKit, a software platform dedicated to the rapid prototyping of CASE environment. FrameKit architecture is similar to the ECMA reference model. It focuses on the quick definition of new graphical representations, handled by a generic user interface. FrameKit also contains a development kit composed of program libraries in various languages (C, Ada and Unix shell). This eases both the implementation and integration of new tools. FrameKit also has good capabilities to integrate software components that were not especially designed for it. FrameKit is operational and we have used it to build the CPN-AMI 2.0 CASE environment that implements a design methodology for distributed systems. To achieve it, we had to describe three formalisms (one is hierarchical) and register the services of a dozen tools. The first version, released on Internet in the first quarter of 1997 () is quite satisfactory. We plan to enrich it with new mechanisms to ease the quick design of code generators as well as model simulators.

FrameKit et CPN-AMI sont disponibles sur Internet.

The present article introduces a holistic approach to ship design, as it is being developed in the Horizon 2020 EU project HOLISHIP (www.holiship.eu). The project deals with the development of design and virtual prototyping simulation platforms, which integrate software tools for all major ship design disciplines and optimization objectives, namely, building and operational cost, energy efficiency, safety, environmental footprint, and life cycle cost/impact assessment. It enables the seamless mathematical multi-objective optimization of ship design with governing design constraints and the exploration of the huge design space by parametric modeling of the ship design system and its components. The article outlines the integration of the essential software tools into the software platform and demonstrates the functionality and benefits of the HOLISHIP approach by brief presentations of typical case studies. Introduction The pattern of seaborne trade and goods transportation is changing, and so do the vessels of transportation. They need to adapt to changes in customer and market requirements, changes in cargo types and volumes, and new legislation for the safety of ships and the protection of the marine/aerial environment. Increased requirements for energy efficiency and the control of GHG emissions and the inherent uncertainties regarding fuel cost and future types of marine fuels pose extra challenges. This calls for significant advances in the approach to ship design and operation to meet continuously changing requirements over ship’s life cycle by holistic, efficient, and easy-to-use design procedures and software systems.

Purpose To perform research in image-guided interventions, researchers need a wide variety of software components, and assembling these components into a flexible and reliable system can be a challenging task. In this paper, the NifTK software platform is presented. A key focus has been high-performance streaming of stereo laparoscopic video data, ultrasound data and tracking data simultaneously. Methods A new messaging library called NiftyLink is introduced that uses the OpenIGTLink protocol and provides the user with easy-to-use asynchronous two-way messaging, high reliability and comprehensive error reporting. A small suite of applications called NiftyGuide has been developed, containing lightweight applications for grabbing data, currently from position trackers and ultrasound scanners. These applications use NiftyLink to stream data into NiftyIGI, which is a workstation-based application, built on top of MITK, for visualisation and user interaction. Design decisions, performance characteristics and initial applications are described in detail. NiftyLink was tested for latency when transmitting images, tracking data, and interleaved imaging and tracking data. Results NiftyLink can transmit tracking data at 1,024 frames per second (fps) with latency of 0.31 milliseconds, and 512 KB images with latency of 6.06 milliseconds at 32 fps. NiftyIGI was tested, receiving stereo high-definition laparoscopic video at 30 fps, tracking data from 4 rigid bodies at 20–30 fps and ultrasound data at 20 fps with rendering refresh rates between 2 and 20 Hz with no loss of user interaction. Conclusion These packages form part of the NifTK platform and have proven to be successful in a variety of image-guided surgery projects. Code and documentation for the NifTK platform are available from http://www.niftk.org. NiftyLink is provided open-source under a BSD license and available from http://github.com/NifTK/NiftyLink. The code for this paper is tagged IJCARS-2014.

International audience; Abilities and Capabilities are different concepts. Classical challenges in robotic arise between theoretical computations and realistic efficient feedbacks. We propose a software platform, trying to split the necessary level of (1) actions (abilities), (2) perceptions of sequences of actions, (3) diagnosis and (4) supervision in order to introduce more reactivity and bring together Artificial Intelligence and Autonomous Robotics. Our first experiments will cope with cognitive mapping representations and necessary adaptations needed when inconsistent landmarks are introduced.

The DARE platform has been designed to help research developers deliver user-facing applications and solutions over diverse underlying e-infrastructures, data and computational contexts. The platform is Cloud-ready, and relies on the exposure of APIs, which are suitable for raising the abstraction level and hiding complexity. At its core, the platform implements the cataloguing and execution of fine-grained and Python-based dispel4py workflows as services. Reflection is achieved via a logical knowledge base, comprising multiple internal catalogues, registries and semantics, while it supports persistent and pervasive data provenance. This paper presents design and implementation aspects of the DARE platform, as well as it provides directions for future development.

Unmanned Aerial Vehicles (UAVs) applications are becoming more and more researched. “Drones” (UAVs) were mainly used as a military technology but are now becoming a leisure and professional activity for many civilian users. Nowadays UAVs are mostly controlled by the use of a controller that operates in Radio Control (RC), although this method of communication limits the vehicle’s distance to the line of sight of the operator. As a need to overcome the line of sight obstacle, cellular networks provide a mean of connection and as the coverage is increasing they’re a natural solution as Wi-Fi is not present everywhere. In order to accomplish this communication between Drone and Operator, there needs to be a Ground Control Station that provides the user all the tools needed to operate the vehicle. This project provides a software platform that is able to monitor a squad of drones whilst also being able to control one at a time. The platform maintains the communication with the vehicle at all times, and is also be able to receive live-video in order to overcome the beyond line of sight obstacle. Besides this, the application provides an admin user, with the capability of overriding a regular user’s control, assigning the user’s drone to itself for controlling purposes. A public server is used to make the exchanging of messages possible, and to have a centralized control over drones and their respective user. Keywords: Os Veículos Aéreos Não Tripulados (UAVs) são cada vez mais utilizados e desenvolvidos. O que antes era utilizado principalmente como tecnologia militar, tem-se vindo a tornar uma profissão ou um hobbie para muitos civis. Hoje em dia os UAVs são controlados geralmente através de um comando, que opera em Radio Controlo (RC) e, embora seja muito utilizado, este método de comunicação limita a distância do veículo à linha de visão do operador. Este é um obstáculo que se tem procurado ultrapassar e as redes móveis providenciam o meio necessário para tal. Desta forma e como a cobertura das redes móveis tem aumentado progressivamente é hoje em dia uma alternativa ao Wi-Fi que não tem o mesmo alcance nem a mesma cobertura. Para que a comunicação entre drone e operador seja viável, tem que existir uma estação de controlo que forneça ao utilizador todas as ferramentas necessárias para operar o veículo. Este projeto visa a criação de uma plataforma de software que seja capaz de monitorizar uma esquadra de UAVs e seja também capaz de controlar um aparelho de cada vez. A plataforma mantém a comunicação com o veículo em todos os momentos, e permite ainda a receção de vídeo ao vivo, superando assim o obstáculo da linha de vista. Também é disponibilizada a um administrador a capacidade de retirar o controlo dos utilizadores aos seus drones alterando assim o responsável pelo controlo. É também utilizado um servidor público de forma a tornar a troca de mensagens possível e também por outro lado, controlar de forma centralizada os drones e os seus respetivos utilizadores.
