Design patterns capture recurring patterns of object-oriented design. This tutorial will provide a perspective on what it’s like to design and implement applications against a backdrop of design patterns. Furthermore, by carrying the designs through to implementation, we will demonstrate the way in which design patterns may or may not be reflected directly in the implementation. We will discuss...

The document describes and examines possibilities of run-time variability in real-time embedded component systems. Namely it formally describes support of operating modes. The report introduces a reconfiguration mechanism based on properties and relations between them. The mechanism is designed to facilitate a straight forward modeling of operating modes and reconfiguration rules and preserves ...

A unified controlled medical vocabulary has been cited as one of the grand challenges facing Medical Informatics. We would restate this challenge as ‘achieving a re-usable and application-independent representation of medical concepts.’ Achieving a re-usable representation of medical concepts is a pre-requisite for meeting two key strategic goals of the next decade of the development in medical...

The paper presents a new information technology approach for simulation based systems capable of serving multiple purposes by composition of components. Based on the High Level Architecture for Modeling and Simulation (HLA) software architecture for distributed simulation systems, this approach takes into account the need for flexibility, re-usability and interoperability in order to be applica...

To avoid multiple works in designing user interfaces for different devices and interaction modalities, the use of a meta-language like UIML seems to be appropriate in order to start with a general UI description and provide mappings to different target devices. For the support of mobile devices and to improve re-usability of user interface definitions, we introduce the language DISL that modifi...

We describe the architecture and design for the Distributed Mission Training Integrated Threat Environment (DMTITE) system. DMTITE supports the development and deployment of different types of computer generated actors (CGAs) in large-scale Distributed Interactive Simulation (DIS) and High Level Architecture (HLA) based simulations. To address issues in software architecture, design, and protot...

In this work, we present a study of Aflatoxin M1 detection by photonic biosensors based on Si₃N₄ Asymmetric Mach-Zehnder Interferometer (aMZI) functionalized with antibodies fragments (Fab'). We measured a best volumetric sensitivity of 10⁴ rad/RIU, leading to a Limit of Detection below 5 × 10(-7) RIU. On sensors functionalized with Fab', we performed specific and non-specific sensing measureme...

Ontology mapping is a task aiming to align semantic resources in order to foster the re-use of information and to enable the knowledge and data expressed in the matched ontologies to interoperate. When ontology mapping algorithms are applied in practice, a manual refinement is furtherly necessary for validating the correctness of the resulted resource, especially, as it happens in real-world ca...

Requirements analysis for web applications still needs to employ effective RE practices to accommodate some distinctive aspects: capturing high-level communication goals, considering several user profiles, defining hypermedia-specific requirements, and reusing requirements for an effective usability evaluation. Techniques should be usable, informal, require little training effort, and show rela...

This paper deals with a parallel approach to the verification of consistency aspects of an industrial product configuration data base. The data base we analyze is used by DaimlerChrysler to check the orders for cars and commercial vehicles of their Mercedes lines. By formalizing the ordering process and employing techniques from symbolic computation we could establish a set of tools that allow ...
