  • system approach to design Generic Software for real time control of flexible manufacturing systems
    Systems Man and Cybernetics, 1996
    Co-Authors: Maria Pia Fanti, B Maione, G Piscitelli, Biagio Turchiano
    Abstract:

    Potentially, flexible manufacturing systems (FMSs) possess the ability to attain efficiency and versatility in small batches, variable mix production. However, the FMS potentiality is not yet fully used, because of the high cost of specific control Software. Hence, a Generic Software, usable in an arbitrary FMS, producing an arbitrary part mix, appears as an important means to minimize programming and re-programming effort. In this context, modeling and control problem formalization emerge as a main issue. In this paper the authors refer to Zeigler's system-theoretic formalism for modeling the dynamics of a Generic FMS at the job release and job how levels. The authors' discrete event dynamic system (DEDS) model establishes an abstract comprehensive framework for developing a Generic control Software at such levels. The model is able to represent both hardware/Software components of the FMS and processing activity plans with a common "language". A modular structure underlies the description of both the shop-floor dynamics and control rules. So, the Software architecture emerges as a direct consequence of the proposed approach and consists of three main parts: the system state knowledge base, the job release manager and the job flow manager.

  • system approach to a Generic Software specification for flexible manufacturing system job flow management
    International Journal of Systems Science, 1992
    Co-Authors: Maria Pia Fanti, B Maione, G Piscitelli, Biagio Turchiano
    Abstract:

    Programmable automation is a key factor to fully exploit the potentiality of flexible manufacturing systems (FMS). In particular, the flexibility of the control Software acting at the operational level, allows one to make the control activities easier to program and re-program. This characteristic needs a Generic Software able to control an arbitrary FMS producing an arbitrary part-mix, according to arbitrary control strategies. Turning attention to the operational job flow management, a typical FMS is modelled as a discrete-event dynamic system in a formal and unambiguous way. The system state and its transitions (i.e. logical and physical entities, their attributes and relationships and the mechanism ruling their modifications in time) are described. The discrete-event model allows one to point out the organization of a Generic Software for job flow management, in terms of its inputs, outputs, knowledge base and decision-making processes.

  • Engineering affective computing: a unifying Software architecture
    2009
    Co-Authors: Alexis Clay, Nadine Couture, Laurence Nigay
    Abstract:

    In the field of affective computing, one of the most exciting motivations is to enable a computer to sense users' emotions. To achieve this goal an interactive application has to incorporate emotional sensitivity. Following an engineering approach, the key point is then to define a unifying Software architecture that allows any interactive system to become emotionally sensitive. Most research focus on identifying and validating interpretation systems and/or emotional characteristics from different modalities. However, there is little focus on modeling Generic Software architecture for emotion recognition. Therefore, we propose an integrative approach and define such a Generic Software architecture based on the grounding theory of multimodality. We state that emotion recognition should be multimodal and serve as a tool for interaction. As such, we use results on multimodality in interactive applications to propose the emotion branch, a component-based architecture model for emotion recognition systems that integrates itself within general models for interactive systems. The emotion branch unifies existing emotion recognition applications architectures following the usual three-level schema: capturing signals from sensors, extracting and analyzing emotionally-relevant characteristics from the obtained data and interpreting these characteristics into an emotion. We illustrate the feasibility and the advantages of the emotion branch with a test case that we developed for gesture-based emotion recognition.

  • From Single-User Architectural Design to PAC*: a Generic Software Architecture Model for CSCW
    1997
    Co-Authors: Gaëlle Calvary, Joelle Coutaz, Laurence Nigay
    Abstract:

    This article reports our reflection on Software architecture modelling for multi-user systems (or groupware). First, we introduce the notion of Software architecture and make explicit the design steps that most Software designers in HCI tend to blend in a fuzzy way. Building on general concepts and practice from main stream Software engineering, we then present a comparative analysis of the most significant architecture models developed for singleand multi-user systems. We close with the presentation of PAC*, a new architectural framework for modelling and designing the Software architecture of multi-user systems. PAC* is a motivated combination of existing architectural models selected for the complementarity of their "good properties". These include operational heuristics such as rules for deriving agents in accordance to the task model or criteria for reasoning about replication, as well as properties such as support for style heterogeneity, portability, and reusability.

  • Generic Software framework for adaptive applications on fpgas
    Field-Programmable Custom Computing Machines, 2009
    Co-Authors: Suhaib A Fahmy, Jorg Lotze, Juanjo Noguera, Linda Doyle, Robert P Esser
    Abstract:

    Adaptive systems are set to become more mainstream, as numerous practical applications in the communications domain emerge. FPGAs offer an ideal implementation platform, combining high performance with flexibility. While significant research has been undertaken in the area of FPGA partial reconfiguration, it has focussed primarily on low-level architecture-specific implementations. Building upon this previous work, we present a system model and Software architecture for implementing runtime adaptive applications on FPGAs, separating the control and processing planes and abstracting away the details of hardware reconfiguration from the system designer. Hardware processing components appear as Software components in the runtime system, enabling their inclusion in adaptive applications. We present an adaptive wireless application, demonstrating the use of the model and Software architecture.
