Software Business in the Telecommunications Sector
2012
Operations and Business Support Systems (OSS/BSS) software of Communication Service Providers (CSP's) can be developed internally within the CSP or acquired from a Software Vendor. The software industry lifecycle model hypothesizes that software development is internal in the beginning of the industry's lifecycle, and that the share of external products increases when it matures. Empirical evidence shows signs of the OSS/BSS software industry approaching maturity. Current and future developments of the industry include the possibilities of utilizing the Software-as-a-Service (SaaS) model and Open Source software (OSSw). Both have gained increasing interest by the CSP's. However, the relativ…
ISO Initiatives on Software Product Line Engineering: Vision and Current Status Invited Talk for Variability@ER2011
2011
Software product line engineering and management is still a relatively young discipline and its industrial diffusion is somewhat limited, partly due to the lack of international standards. It involves sub-disciplines that may not necessarily be mature enough yet for standardization. On the other hand, well-focused standardization efforts contribute to the diffusion of best product line practices and help raise the maturity of these practices. Careful roadmapping and execution of the standardization initiative is thus vital. This talk discusses the current roadmap for the international standardization initiative of software product line engineering and management methods and tools and the st…
Increasing understanding and confidence in THM simulations of engineered barrier systems
2020
Previous studies on the modelling of coupled thermo-hydro-mechanical (THM) processes in bentonite-based engineered barrier systems (EBSs) showed the sensitivity of the output quantities to changes in the input parameters. To investigate the effects of uncertainties on the modelling results, to improve the understanding of the coupled processes active in the repository near field and to gain in-depth understanding of model uncertainties of different codes, a sensitivity analysis and code comparison of EBS simulations was performed within the Task Force on Engineered Barrier Systems. The analysis included variations in material parameter values, boundary and initial conditions, considered phy…
Specifying Patterns for Mobile Application Domain Using General Architectural Components
2005
Software companies adopt patterns as a means to improve architecture and design practices. During recent years, the application of patterns has extended from general software applications to specific problem domains. In a new domain, suitable patterns fitting to the essential design problems in the new context need to be identified. In this paper, we introduce a general architectural model of mobile applications, which can be used to identify and organise essential patterns in mobile-application design process. This model is employed to construct a high-level architecture of a particular application. For each component of the architecture, the model may suggest candidate patterns that can b…
Control Design for Discrete-Time Fuzzy Systems with Disturbance Inputs via Delta Operator Approach
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher: http://dx.doi.org/10.1155/2013/724918 Open Access This paper is concerned with the problem of passive control design for discrete-time Takagi-Sugeno (T-S) fuzzy systems with time delay and disturbance input via delta operator approach. The discrete-time passive performance index is established in this paper for the control design problem. By constructing a new type ofLyapunov-Krasovskii function (LKF) in delta domain, and utilizing some fuzzy weighing matrices, a new passive performance condition is proposed for the system under consideration. Based on the condition, a st…
Gabor filters in industrial inspection: a review. Application to semiconductor industry
2005
This paper focuses on reviewing some recent works of the use of Gabor filters dealing with industrial applications. After a brief recall of Gabor filter basis, the two usual uses of Gabor filters are recalled: filter bank approach and filter design approach. The third part presents recent published works domain by domain. A fourth part exposes our own work with Gabor Filters for defect detection on semiconductor. A short conclusion summarizes the paper.
A preliminary method for the numerical prediction of the behavior of air bubbles in the design of Air Cavity Ships
2016
Air-cavity ships (ACS) are advanced marine vehicles that use air injection under hull to improve the vessel’s hydrodynamic characteristics. Although the concept of drag reduction by supplying gas under the ship’s bottom was proposed in the 19th century by Froude and Laval, at this time there are not many systematic studies on this subject. This paper is a preliminary work with the purpose of being a basic tool for the design of the ACS with computational fluid dynamic methods. The study aims to conduct a series of computational tests to compare the numerical models of bubble with experimental data. The first step of this study was to investigate the behavior of free bubble in water, conside…
Welcome to MTI—A New Open Access Journal Dealing with Blue Sky Research and Future Trends in Multimodal Technologies and Interaction
2016
In this era of massive use of computers and other computational devices (e.g., low-cost wearable sensors, smartphones, other smart devices, etc.), the nature of digital data is becoming more complex and heterogeneous.
THE METAMODEL: A STARTING POINT FOR DESIGN PROCESSES CONSTRUCTION
2010
The construction of ad-hoc design processes following the Situational Method Engineering (SME) paradigm is currently carried out by adopting a set of phases for which, until now, no well defined techniques and guidelines have been established. The consequence is that organizations are very dependent on method designers' skills. In this paper, we propose an approach based on SME for constructing customized agent oriented design processes. Our approach adopts the metamodel as the most important factor leading to the selection and assembly of method fragments and an algorithm for establishing the instantiation order of metamodel elements. The algorithm makes the proposed approach repeatable a…
