Digitization and Preservation of Cultural Heritage Products
2017
Cultural heritage encompasses various aspects of a nation's history. Cultural heritage artifacts are considered as priceless items that need special care. Since the wide adoption of new digital technologies, documenting and storing cultural heritage assets became more affordable and reliable. These records are then used in several applications. Researchers saw the opportunity to use digital heritage recordings for long-term preservation. They are considering cultural heritage artifacts as products, and the history behind them as a product lifecycle. In this paper, we present the research progress in cultural heritage digital processing and preservation, highlighting the most impactful advan…
Examining Enterprise Architecture Definitions : Implications from Theory and Practice
2019
This study explores the evolving discipline of Enterprise Architecture (EA) and the various definitions given to EA in literature and by practitioners. Due to the potential benefits, such as business and IT alignment, academics and practitioners have maintained an interest in enterprise architecture. EA has been developed outside of scientifically tested foundations, and is characterized by diversified views, seen in varied definitions given to the concept. Prior research has identified the need for conceptual strengthening as a necessity for the maturing the discipline. We contribute to this on-going discussion with a systematic literature review on the state-of-the-art of EA definitions a…
A Practical Approach to EA Planning and Development: the EA Management Grid
2004
Enterprise Architecture is gaining interest as a managerial tool for managing corporate ICT assets and their interplay. Our prior studies indicate that an ICT provider’s viewpoint on EA consulting, planning and development seems to be lacking in the proposed methodologies. Considering both literature and practical EA cases, we suggest an approach that supports restricted assignments in EA management. We present an EA Grid for the management of EA descriptions, requirements, constraints, as well as project tasks and deliverables, task preliminaries and dependencies in EA consulting and development. peerReviewed
Collaborative EA Information Elicitation Method : The IEM for Business Architecture
2015
This study contributes to the enterprise architecture (EA) methodologies by suggesting a method for eliciting architecture requirements: gathering both the current architecture information, and the development needs and requirements for the business architecture (BA) dimension in EA planning. Most of all EA dimensions, the developing of the BA requires collaboration with various non-IT stakeholders. It presents thus challenges to the IT department, or the consultancy involved in EA related efforts. The contribution of the various stakeholder groups as informants is, however, crucial to well founded EA design decisions. The suggested method takes related IS development fields as starting poi…
A composite indicator for water meter replacement in an urban distribution network
2012
In water supply management, volumetric water meter are typically used to measure users' consumption. With water meters, utilities can collect useful data for billing, assess the water balance of the system, and identify failures in the network, water theft and anomalous user behaviour. Despite their importance, these instruments are characterised by intrinsic errors that cause so-called apparent losses. The complexity of the physical phenomena associated with metering errors in aging water meters does not allow meter replacement to be guided by single parameters, such as the meter age or the total volume passed through the meter. This paper presents a meter replacement strategy based on a c…
The metrological characterization of the static meters for reactive energy in the presence of harmonic distortion
2007
For the electricity metering for billing purposes in distribution systems, the static meters are substituting the traditional inductive meters. Thus, the evaluation of the performances of such equipments is required, also in the presence of disturbances affecting the power systems. With respect to this, this paper analyzes the main aspects related to the metrological characterization of the static meters for reactive energy in the presence of harmonic distortion. Particular attention is given to the reference standard meters, that are not considered by the actual in-force Standards. The analysis is supported by several experimental tests.
EA Planning, Development and Management Process for Agile Enterprise Development
2005
In this study, we suggest an enterprise architecture (EA) development process model suitable for EA projects limited in scope and time. Several EA process models have been put forward, which have in common the idea of comprehensive EA management and development that is generic, cyclic and ongoing in a user organization. The suggested models are of varying level of abstraction. It is not simple to select the right issues from them for a restricted development effort. An ICT services provider needs a process model to follow in EA consulting and development projects. This approach is also needed for incremental EA development by user organizations. Starting with the suggested EA process models…
Static meters for the reactive energy in the presence of harmonics: an experimental metrological characterization
2009
Electricity metering plays a crucial role for all the commercial transactions on the energy market. Thus, an accurate evaluation of the performance of the electricity metering equipment is required not only in the reference operating conditions but also in the presence of disturbances affecting the power systems. As regards this matter, this paper analyzes the main aspects related to the metrological characterization of the static meters for the reactive energy in the presence of harmonic distortion. Attention is focused not only to the meters covered by the current standards but also to the meters of better accuracy and to the reference standard meters. The analysis is supported by several…

Systems Approaches in the Enterprise Architecture Field of Research: A Systematic Literature Review
2018
This study explores the use of the systems approaches (systems thinking and systems theories) as the theoretical underpinnings for Enterprise Architecture (EA) research. Both the academic and the practitioner communities have maintained an interest in EA due to its potential benefits, promising for the recent technological and business advances. EA as a research area is, however, characterized by diversified views depicted in different definitions of the concept, and no acknowledged common theoretical foundation. A number of prior studies have noticed this gap in the EA field of research, and called for a strengthening of the theory of EA. Variegated systems approaches have been suggested a…
