In parallel with China’s growing construction market, there has been an influx of foreign architectural and engineering design firms into the Chinese construction market. Those firms generally form partnerships with local Chinese firms or institutions to overcome various complications in the country. Adding to the complexity, relatively recent technologies such as Building Information Modelling...

Collaborative design is an iterative process of selecting and evaluating solutions under potentially conflicting requirements, a concept central to Building Information Modelling (BIM) implementation. Previous research has shown that design can be better understood via computational argumentation-based dialogue. We suggest that in BIM context different types of dialogue should be considered and...

General contractors usually need to handle subcontractor’s payment requests periodically according to the progress of the construction project. The documents required for payment requests are related to various types of information generated from construction work items. Consequently, construction company needs to spend a lot of efforts to verify and approve the submitted documents in order to ...

The structural, functional, and production views on learning objects influence metadata structure and vocabulary. We drew on these views and conducted a literature review and in-depth analysis of 14 learning objects and over 500 components in these learning objects to model the knowledge framework for a learning object ontology. The learning object ontology reported in this paper consists of 8 ...

This paper discusses an ongoing research that is conducted to develop a framework that will support employers in making informed and sound decision in defining their requirements. The aim of this research is to develop an ontology-based, BIM enabled framework for EIR (OntEIR), it will examine the ability of this framework in capturing, analysing, and translating these requirements based on an o...

A new perceptually significant block-edge impairment metric (PS-BIM) is presented in this paper as a quantitative distortion measure to evaluate blocking artifacts in block-based video coding. This distortion measure does not require the original video sequence as a comparative reference and is found to be consistent with subjective evaluation.

In sensor data management, it is often useful to collect statistics about state changes of an observed phenomenon. The most basic case is to keep track of how often certain transitions, e.g. from state c to d, have occurred. In our research, we consider a discrete state space and timeline. For example, in the above figure, the state space corresponds to actual two-dimensional space and is divid...

The availability of enormous volumes of heterogeneous Cyber-Physical-Social (CPS) data streams allow design and implementation of networks to connect people with essential life resources. We call these networks Social Life Networks (SLNs). We are developing concepts, technology, and infrastructure to design and build these networks. SLNs will be helpful in addressing several essential societal ...
