    Towards Semantic Interoperability Service Utilities

    The paradigm of Interoperability Service Utility (ISU) is considered as one of the grand challenges in research of Enterprise Interoperability. In this paper, the authors discuss on the relevance and impact of the current ISU research to the semantic interoperability in general and propose an original architecture for implementation of...

    Semantic Interoperability for Dynamic Product-Service Business Ecosystems

    Dynamic Product-Service Business Ecosystems (DPSBEs) are collaborative forms that aim to handle product-service business actions in a business ecosystem by creating, sharing, using and reusing information across functional teams and enterprise boundaries. DPSBEs depend on the ability of their members' information systems to interoperate. This ability is related to making...

    An Approach for Formalizing the Supply Chain Operations

    Reference models play an important role in the knowledge management of the various complex collaboration domains (such as Supply Chain Networks). However, they often show a lack of semantic precision and, they are sometimes incomplete. In this paper, the authors present an approach to overcome semantic inconsistencies and incompleteness of...

    Performance Analysis of Dual Selection-Based Macrodiversity System Over Channels Subjected to Nakagami-M Fading and Gamma Shadowing

    This paper studies wireless communication system following micro-diversity to mitigate the effects of short-term fading and macro-diversity processing to reduce shadowing effects. N-branch Maximal-Ratio Combining (MRC) is implemented at the micro level (single base station) and Selection Combining (SC) with two base stations (dual diversity) is implemented at the macro...

    Integrated Product Ontologies for Inter-Organizational Networks

    Purpose of this paper is to propose approach and technical infrastructure for improvement of inter-organizational networks' response in product information acquisition and management. Different approaches (industrial categorization schemes, functional decomposition and semantic web) for management of product information are analyzed in context of inter-organizational networks. Process for semantic alignment of...

    Business Process Management Maturity Model and Six Sigma: An Integrated Approach for Easier Networking

    Business process management maturity model enables description of ''As-is'' enterprise's state, from the perspective of process management maturity. In the hart of this model there are five factors or levers, critical for successful business process management implementation. These factors are: strategic alignment, process management, methods and technology, employees and business...

    The Performance of Macrodiversity System in the Presence of Long-Term and Short-Term Fading

    Probability Density Function (PDF), moments of signal and Amount of Fading (AF) at the output of macro diversity system in closed form are obtained. Moreover, Level Crossing Rate (LCR) of signal at output of macro diversity system is analytically derived and used to study Average Fade Duration (AFD) of the...

    Impact Of Political Affiliation On Bank Profitability In Nigeria

    To improve the understanding of bank profitability in Nigeria, this paper sought to econometrically analyze the relationship between political affiliation and bank profitability. Using a panel data set comprising 115 observations of 14 unique banks over the last democratic dispensation (1999-2007), regression results reveal that political affiliation has a positive...

    An Overview of On-Chip Buses

    The electronics industry has entered the era of multi-million-gate chips, and thereXs no turning back. This technology promises new levels of integration on a single chip, called the System-on-a-Chip (SoC) design, but also presents significant challenges to the chip designer. Processing cores on a single chip, may number well into...

    The Semantics of Collaborative Tagging System

    In this paper, the authors adopt a system-oriented approach to the collaborative tagging and define it as a set of interactions in the system of web resources. The system of web resources is modeled as a set of interacting agents and collaborative tagging is represented as concurrent initiation of inter-actions...
