An expert system hybrid architecture to support experiment management
2014
Specific expert systems are used for supporting, speeding-up and adding precision to in silico experimentation in many domains. In particular, many experimentalists exhibit a growing interest in workflow management systems for making a pipeline of experiments. Unfortunately, these type of systems does not integrate a systematic approach or a support component for the workflow composition/reuse. For this reason, in this paper we propose a knowledge-based hybrid architecture for designing expert systems that are able to support experiment management. This architecture defines a reference cognitive space and a proper ontology that describe the state of a problem by means of three different per…
Fifth Generation Networking Principles for a Service Driven Future Internet Architecture
2010
Published version of an article published in Wireless Personal Communications, vol. 57:393-411. Also available from the publisher at: http://dx.doi.org/10.1007/s11277-010-0076-7 The vision of all-IP networks where IP forms the simple common layer understandable across the whole network has undeniable advantages. However, such simplicity comes as a major hurdle to flexibility and functionality to the architecture. This is evident from the increasingly numerous and complex engineering solutions and optimizations required to accommodate essential qualities like mobility, security, realtime communication support etc or to mitigate the shortcomings inherent in the 'traditional Internet' architec…
Government Enterprise Architecture Grid Adaptation in Finland
2009
In government, support for strategic political steering, administrative and cross-sectoral development, and integration of processes and systems can be sought out of enterprise architecture (EA) planning. To facilitate this, a proper EA method covering essential government levels is needed. A constructive case study has been carried out to create an adaptation model of Finnish government EA (GEA) grid. The study builds on general principles of method adaptation and observations about GEA method engineering and its pilot adaptations in Finnish State Administration. The model presents systematic guidelines for situational GEA grid adaptation and reuse in Finnish State administration. The mode…
Business architecture development at public administration - Insights from government EA method engineering project in Finland
2008
Governments worldwide are concerned for efficient production of services to customers. To improve quality of services and to make service production more efficient, information and communication technology (ICT) is largely exploited in public administration (PA). Succeeding in this exploitation calls for large-scale planning which embraces issues from strategic to technological level. In this planning the notion of enterprise architecture (EA) is commonly applied. One of the sub-architectures of EA is business architecture (BA). BA planning is challenging in PA due to a large number of stakeholders, a wide set of customers, and solid and hierarchical structures of organizations. To support …
A unified radio control architecture for prototyping adaptive wireless protocols
2016
Experimental optimization of wireless protocols and validation of novel solutions is often problematic, due to limited configuration space present in commercial wireless interfaces as well as complexity of monolithic driver implementation on SDR-based experimentation platforms. To overcome these limitations a novel software architecture is proposed, called WiSHFUL, devised to allow: i) maximal exploitation of radio functionalities available in current radio chips, and ii) clean separation between the logic for optimizing the radio protocols (i.e. radio control) and the definition of these protocols.
Toward a Reference Architecture for Archival Systems
2013
Long-term preservation of product data is imperative for many organizations. A product data archive should be designed to ensure information accessibility and understanding over time. Approaches such as the Open Archival Information System (OAIS) Reference Model and the Audit and Certification of Trustworthy Digital Repositories (ACTDR) provide a framework for conceptually describing and evaluating archives. These approaches are generic and do not focus on particular contexts or content types. Enterprise architecture provides a way to describe systems in their potentially complex environments.
A New HLA-Based Distributed Control Architecture for Agricultural Teams of Robots in Hybrid Applications with Real and Simulated Devices or Environme…
2011
The control architecture is one of the most important part of agricultural robotics and other robotic systems. Furthermore its importance increases when the system involves a group of heterogeneous robots that should cooperate to achieve a global goal. A new control architecture is introduced in this paper for groups of robots in charge of doing maintenance tasks in agricultural environments. Some important features such as scalability, code reuse, hardware abstraction and data distribution have been considered in the design of the new architecture. Furthermore, coordination and cooperation among the different elements in the system is allowed in the proposed control system. By integrating …
A virtual integration—The management control system in a multinational enterprise
2008
Abstract This paper draws on actor-network-theory, especially Law and Hassard [Law, J., Hassard, J. (Eds.), 1999. Actor Network Theory and After. Blackwell, Malden, MA] and Latour [Latour, B., 2005. Reassembling the Social. An Introduction to the Actor-Network-Theory. Oxford University Press, Oxford] to investigate how a division-wide management control system was created in a multinational enterprise. The empirical findings were gathered from different actors involved in the implementation of enterprise's ABC and ERP projects. Our study focuses on the ontological politics [Mol, A.-M., 1999. Ontological politics. A word and some questions. In: Law, J., Hassard, J. (Eds.), Actor Network Theo…
Discovering and creating business opportunities for cloud services
2016
This study focuses on how the opportunities for cloud services are detected.The study develops a framework to detect and exploit cloud-based opportunities.This study incorporates entrepreneurship theories to extend and enrich IS research. Cloud computing provides new business opportunities for firms selling or using cloud services. However, little is known about how software firms detect and exploit these opportunities. Based on in-depth qualitative case studies, this study identified two different pathways followed by software firms when they detect and exploit opportunities. In the first pathway, the opportunity is based on an existing problem and need in the market. In the case firms, th…
Some Insights on the Changing Architecture of the World’s Top 100 Multinationals
2016
Abstract Premise: globalization represents both the fertile background and the accountable foreground that accompanies the evolution of TNCs/MNEs, within a self-enforcing spiral of co-evolution which gratifies the winners and discards the losers. Argument: UNCTAD’s Top 100 non-financial TNCs/MNEs gathers together, since 1993, some of the most prominent winners of the above mentioned processes, making this instrument one of the best indicators and benchmarks in terms of both globalization and transnationalization – when analyzed at a given moment in time (for a particular year), and even more relevant when analyzed dynamically and by comparison. Context: two major global shifts have occurred…
