Towards a Game-Design Framework for Evidence-Based Clinical Procedure Libraries
2019
Serious games have been and currently are used for multiple purposes other than just entertainment, such as education, healthcare or emergency management. This research presents game-design elements based on specific functional and professional requirements among which usability plays a key role. The aim of the research is to steer the direction towards a game-design framework for evidence-based clinical procedure libraries (eCPL). For context analysis and game-element presentation, a "serious application" example is shown to illustrate the improvement through game-design elements. A context analysis was required to select suitable game-design elements to target system usability and solve s…
Implementing Ethics in AI: Initial Results of an Industrial Multiple Case Study
2019
Artificial intelligence (AI) is becoming increasingly widespread in system development endeavors. As AI systems affect various stakeholders due to their unique nature, the growing influence of these systems calls for ethical considerations. Academic discussion and practical examples of autonomous system failures have highlighted the need for implementing ethics in software development. However, research on methods and tools for implementing ethics into AI system design and development in practice is still lacking. This paper begins to address this focal problem by providing elements needed for producing a baseline for ethics in AI based software development. We do so by means of an industri…
Exploring the generative power of performance measurement systems design
2019
Abstract Prior studies recognise the enabling power of incompleteness in the design of Performance Measurement Systems (PMS). We add to these studies by exploring the ‘time dimension’ of incompleteness as a way to delve into the generative power of design. To this aim, we rely upon the experience of a knowledge-intensive organization during the design of a new PMS. While knowledge complexity engaged the participants within an open-ended design process, incomplete measures were associated with unfolding memories of the past and confident beliefs in future solutions, which generated effects through the knowledge gaps that they entailed, as well as through the projections in the past and in th…
Improving energy efficiency of commercial buildings by Combined Heat Cooling and Power plants
2020
Abstract Commercial buildings play a key-role in the energy consumption of the building sectors. Recent statistics have shown that as the number of commercial buildings is continuously increasing, their effects on energy consumption are expected to grow. These buildings are characterized by high energy demand mainly due to lighting and HVAC requirements. Rooms of energy saving exist by considering that: (i) electricity demands and HVAC requirements occur simultaneously during the day and (ii) both demands are currently satisfied by using separate energy systems. It is apparent that the adoption of polygeneration systems could represent a valid solution to achieve energy savings. To this aim…
AMCAS: Advanced Methods for the Co-Design of Complex Adaptive Systems
2006
Abstract This work proposes a new approximation to design and program Complex Adaptive Systems (CAS), these systems comprise neural network, intelligent agents, genetic algorithms, support vector machines and artificial intelligence systems in general. Due to the complexity of such systems, it is necessary to build a design environment able to ease the design work, allowing reusability and easy migration to hardware and/or software. Ptolemy II is used as the base system to simulate and evaluate the designs with different Models of Computation so that an optimum decision about the hardware or software implementation platform can be taken.
Assessment of the Usability and Accuracy of the Simplified One-Diode Models for Photovoltaic Modules
2016
Models for photovoltaic (PV) cells and panels, based on the diode equivalent circuit, have been widely used because they are effective tools for system design. Many authors have presented simplified one-diode models whose three or four parameters are calculated using the data extracted from the datasheets issued by PV panel manufactures and adopting some simplifying hypotheses and numerical solving techniques. Sometimes it may be difficult to make a choice among so many models. To help researchers and designers working in the area of photovoltaic systems in selecting the model that is fit for purpose, a criterion for rating both the usability and accuracy of simplified one-diode models is p…
Modelling Offices Through Discourse Analysis: A Comparison and Evaluation of SAMPO with OSSAD and ICN
1992
In a previous paper the importance of framing office communications in terms of discourse analysis was explored. 2 It also presented an approach based on speech acts and conversations to allow this framing to occur. The approach was termed SAMPO. In this paper, we continue the discussion on discourse analysis by comparing SAMPO with two prominent office modelling approaches, Information Control Nets (ICN) and OSSAD, and discuss its merits in modelling office communications.
Systems engineering activities supporting the heating & current drive and fuelling lines systems integration in the European DEMO breeding blanket
2019
This paper describes the contribution given by the application of the systems engineering approach to the European DEMO Breeding Blanket (BB) integration studies, focussing on the integration of Heating & Current Drive (H&CD) and Fuelling Lines (FL) systems. In particular, attention has been paid to the BB-H&CD and BB-FL interfaces identification, definition and capture of the proper interface requirements necessary to drive the integration process and, as a consequence, supply a feedback for the reciprocal design of the interconnected systems. The defined interfaces are synthetically described in the paper and the results of the interface requirements capture process are shown,…
A Design Theory for Secure Information Systems Design Methods
2006
Many alternative methods for designing secure information systems (SIS) have been proposed to ensure system security. However, within all the literature on SIS methods, there exists little theoretically grounded work that addresses the fundamental requirements and goals of SIS design. This paper first uses design theory to develop a SIS design theory framework that defines six requirements for SIS design methods, and second, shows how known SIS design methods fail to satisfy these requirements. Third, the paper describes a SIS design method that does address these requirements and reports two empirical studies that demonstrate the validity of the proposed framework. peerReviewed
Introduction to the Management of Knowledge Systems Design and Deployment Projects Minitrack
2012
Knowledge systems are increasingly used to support globally distributed work. Projects are a natural means of designing and deploying such systems. There is plenty of literature on the management of information systems design projects and some literature on information systems deployment projects. However, knowledge systems are typically more complex organizationally and socially than most traditional information systems. For example, enterprise resource planning systems typically must be used to get the work done whereas many knowledge systems are voluntary to use. It is reasonable to assume that project management involved in the design and deployment of knowledge systems differs from the…
