Conceptual modelling of adaptive web services based on high-level petri nets
… explicitly separates between orchestrations for modelling rule-intensive single services and choreography for cooperating several services through their governing interactive business rules. Fifthly, the framework is based on a two-level conceptualization: (1) the modelling of any rule-centric …

Semantic and organization considerations in database conceptual modelling : the Semantic Conceptual Organizational Model (SECOM)
… utilization of databases. Such issues include conceptual modelling, organization theory, and semantic theory. The conceptual modelling approach presented in this thesis is developed over three design stages, or model perspectives. In the semantic perspective, concept definitions were developed …

The Applicability of Hypermedia Technology to Database Design
… in particular problem-resolution systems, to the conceptual modelling stage of the database design process. Conceptual modelling produces a representative abstraction (schema) of the data requirements of an organisation. Hypermedia is a form of information representation and management based on …

Requirements engineering with interrelated conceptual models and real world scenes
… a complete, consistent, and unambiguous conceptual description of intended changes (e.g. in respect to software, hardware, or business processes) for a given application domain. Because RE is also a cooperative communication and learn process of stakeholders and requirements analysts the …

A requirements elicitation framework for agent-oriented software engineering.
The hypothesis of this research is as follows: "Conceptual modelling is a useful activity for the early part of gathering requirements for agent-based systems." This thesis examines the difficulties of gathering and expressing requirements for agent based systems, and describes the development of a …

Exploring the impacts of organisational change : a structured prediction approach
… analysis methods used included triangulation and conceptual modelling.

Analysis and design as bricolage
… systems design methods, complexity, ontology and conceptual modelling and how they relate to ISD. This research was conducted within a larger national research project aiming to improve organising practices within IT in organisations. To this end the research followed a participatory action …

The hydrogeological investigation of worked coal measures rocks and its application to the modelling of groundwater flows
… emphasis upon the development of an accurate conceptual model. This is indicative of an overconfidence in the ability to characterise most groundwater systems, by the direct input of hydrogeological data into numerical models.<br/><br/>This thesis describes the hydrogeological investigation of …

Issues of scale in nuclear graphite components
A conceptual model for the determination of the effect of specimen size on the strength of nuclear graphites was developed using abstraction techniques and finite element Analysis (FEA). The model was designed to be able to predict the response of nuclear graphites (primarily IM1-24 graphite) using …

3D conceptual and TOUGH2 modelling of the Waiotapu geothermal field, New Zealand
… system and its surroundings through 3D conceptual modelling and numerical modelling. The conceptual model is created using existing data obtained from surface and subsurface exploration. Leapfrog Geothermal software was used to build the model. This 3D conceptual model was used as the …

Services for activities in group editing 'sage'
… and to test the proposed functionalities. The conceptual modelling follows current CCITT proposals, but a new classification of group activities is proposed: Informative, Objective and Supportive application groups. It is proposed that each of these application groups have their own Service …

A geohydrological study of the Richards Bay area
… to use.in the model. There is a need to develop conceptual models of the region for theicnplementation of the numerical methods. The regional geology is well described in the literature, but observations on a local scale do not always conform to the?regional stratigraphy. Consequently, many …

THE MARKETING AND DISTRIBUTION SYSTEM FOR FRESH FISH IN SOUTH WEST ENGLAND: MODELLING THE EFFECTS OF SUPPLY VARIATION
… system in Devon and Cornwall and develops a modelling framework with forecasting properties within which distribution system problems can be analysed. A review of the marketing and distribution literature reveals that system efficiency and the impacts of changes in external conditions are …

Trusting
… persons as its object. This approach to the conceptual modelling of trust is guided by a specific conjecture, the Settling Conjecture, according to which trust is the state that settles our interactions with persons. I illustrate the merits of this conjecture in its own terms. I also …

Information systems framework for enterprise agility
… or processes should include techniques for modelling enterprises changes explicitly, so as to enhance the understanding of how changes relate to or affect enterprises. In addition, there should be techniques for deriving the elements of an enterprise, e.g., business process and data …

Personal data sovereignty : a sustainable interface layer for a human centered data ecosystem
… This research extends this trajectory through Conceptual Modelling to define a Sovereign Boundary Mechanism (SBM), an independent realm of interaction which enables the principles of decentralisation. Analysis suggests that this interaction is high in friction, requiring considerable …

Supply Chain Management and Logistical Considerations in Distributing Crude Oil from Nigeria to China
… of crude oil exports to China from Nigeria. A conceptual model was developed to identify relevant issues that guide the synergy of China’s requirement for energy security and Nigeria’s crude oil supply capability. Also, both a Delphi survey and an archival research method’s were adopted to …
