In this paper, we develop high-speed evacuation simulator NetMAS based on one-dimensional pedestrian model and propose exhaust testing of evacuation plan. With NetMAS, we take up evacuation from the theater in the commercial complex and present the basic directions.
The paper develops application of techniques from robust and universal hypothesis testing for anomaly detection and change-point detection in dynamic, interconnected systems. This theory is extended using the concept of projected Markov models originally proposed by Claude Shannon. Also presented is a detailed application to anomaly detection from people movements patterns in buildings.
Building information modelling (BIM) is only a tool in the procurement of a building, but it is changing the way the whole process is undertaken. Having a single model which is used by all disciplines requires a different management structure and by consequence a restructuring of the resources required to complete a project.These changes are encompassed in Integrated Practice and more recently Integrated...
Developing sustainable urban environments is complex as it requires consideration of interacting social, economic and environmental sustain ability factors. The task is made even more difficult by the wide variety of stakeholders (e.g. planners, architects, businesses and the public) that may be involved in the process and the lack of a common language for all to understand. This paper describes a...
Road and traffic sign recognition has been of great interest for many years. This paper presents an approach to recognize Swedish road and traffic signs by using support vector machines. We focus on recognizing seven categories of traffic sign shapes and five categories of speed limit signs. Two kinds of features, binary image and Zernike moments, are used for representing the data to the SVM for...
The definition of an oracle function for model transformation is challenging because of the very complex nature of models resulting from a transformation. Validating the correctness of an output model requires checking a large number of properties on the structure and semantics of this model. The oracle function can thus be very complex if it checks every property. In this paper, we identify and discuss...
