The paper presents the facilities offered by the open learner model maintained in the web-based, adaptive, activity-oriented learning environment SCALE (Supporting Collaboration and Adaptation in a Learning Environment), in order to guide online students who become disengaged and support their reengagement. The open learner model (OLM_SCALE) contains and represents information about students' performance...
Our research is focused on developing an ecoinformatics platform to support climate change adaptation in Victoria. A multidisciplinary, cross-organisational approach is taken in developing adaptation strategies to deal with the `diabolical' policy problem of climate change. The platform comprises a number of components including: (i) a metadata discovery tool to support modelling, (ii) a workflow...
This paper, the third in a series, completes the presentation of a proposed set of modifications and extensions to the IMS Learning Design specification with the goal of enabling better support for adaptivity in collaborative learning settings. The extensions presented here target advanced adaptation features that build upon previous work and include: adapting control flows, controlling adaptations...
Model transformation plays an important role in current MDD (Model Driven Development). Combined with direct model manipulation, relational algebra and template theory, this paper presents a formalizing hybrid model transformation for the design in universal collaborative system. Furthermore, it implements an extendible prototype system based on MDA paradigm called CSCWMDA. CSCWMDA specifies a model...
Collaborative simulation is an important technology for complex engineering systems. The challenges of collaborative simulation are especially in model integration, interaction control and time advancement where a variety of collaborative disciplinary subsystems for time-synchronized running are handled dynamically in a distributed environment. In this paper, the formulized paradigm of multidisciplinary...
Due to the fact that the group playing a core role in the collaborative applications, it is necessary provide models which allow us to supply a shared workspace in which users perform their tasks using shared resources, to coordinate the interaction among users and between them and the shared resources, to facilitate the user access to the collaborative applications and shared resources, to support...
The synchronized collaborative design within heterogeneous CAD systems becomes a significant challenge because of the great difference in the modeling operations and underground data structures between different CAD systems. A feasible way is to build a neutral operation to aid the conversion of operations among different CAD systems. This paper first proposes a collaborative architecture with heterogeneous...
With the growth of e-commerce, the development of recommendation systems is helpful for users to select desirable products from all kinds of them. The existing e-commerce recommendation approaches are based on a user's preference on music. However, sometimes, it might better meet users' requirement to recommend products according to emotions. In this paper, we propose a novel framework model for emotion...
The design and development of a complex system as well as the simulation of its dynamic behavior are usually involved in multidisciplinary field knowledge. HLA-based collaborative simulation is an effective way to integrate different disciplinary models together in distributed environments. In this paper, the HLA adaptor is adopted to realize model transformation so that models created through commercial...
The design and development of complex engineering systems generally encompasses multi-disciplinary knowledge and entails systematic analysis at an early design stage. A paradigm known as collaborative simulation is introduced to address this characteristic: that is, decomposing the system into manageable subsystems and incorporating them at simulation run-time. However, many key limitations still...
Over the last decade, recommendation systems (RS) have matured into a valuable approach for assisting online customers in navigating through large product or information spaces. The associated research has described and evaluated a variety of different techniques for proposing items of interest to customers. However, each of these techniques also suffers from several shortcomings. Therefore, depending...
Distributed M&S (modeling and simulation) plays an important role in simulation of engineering and manufacturing process in the past few years. HLA (High level architecture) and Web service make distributed M&S available in a network centric environment, integrating heterogeneous simulations and legacy models. But physical communication and interoperation enabled by HLA need to be enhanced...
This paper analyzes the characteristic of modern product collaborative development process and concludes the demand realizing process management model and puts forward multi-view process management modeling method. Model describes the restriction relation between related element and information flow. The model sustains function view and behavior view and organization view and information view of product...
This paper proposes dynamic and adaptive reliability methods that can be integrated into a collaborative composition framework with dynamic verification and adaptive reliability modeling. The composition process follows a template-based approach with ontology systems where a variety of items can be reused including services, workflows, application templates, and test cases/scripts. Items submitted...
This paper discusses a new approach to dynamically configure generic protocols. Generic protocols are interaction patterns from which all application domain information has been removed. Configuring a generic protocol consists in refining the coarse-grained description of this protocol with the functionality an agent is endowed with for a specific application. In this process the general behaviors...
Collaborative design and simulation is the key technique for complex product development, which is a highly complicated multidisciplinary process. The information sharing and model transferring among different disciplinary domains are the bottleneck of complex product collaborative design and simulation. To solve this problem, this paper proposes the complex product collaborative design and simulation...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
The challenges of deriving early-adopter competitive advantage, even with fabless access to process technology, through leveraging features offered by the advanced, and possibly disruptive, process technologies in real SoC products, are outlined. A structured methodology for addressing these challenges, and bridging the gap between process and design, sufficiently early in the development cycle to...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
