A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu
A Cluster Identification Framework Illustrated By A Filtering Model For Earthquake Occurrences, Zhengxiao Wu
Research Collection School of Economics
A general dynamical cluster identification framework including both modeling and computation is developed.The earthquake declustering problem is studied to demonstrate how this framework applies.A stochastic model is proposed for earthquake occurrences that considers the sequence of occurrencesas composed of two parts: earthquake clusters and single earthquakes. We suggest that earthquake clusterscontain a “mother quake” and her “offspring.” Applying the filtering techniques, we use the solution offiltering equations as criteria for declustering. A procedure for calculating maximum likelihood estimations(MLE’s) and the most likely cluster sequence is also presented.

In this chapter, we consider a class of queries that arise in spatial decision making and resource allocation applications. Assume that a company wants to open a number of warehouses in a city. Let P be the set of residential blocks in the city. P represents customer locations to be potentially served by the company. At the same time, P also comprises the candidate warehouse locations because the warehouses themselves must be opened in some residential blocks.
Making Sustainable Creative/Cultural Space In Shanghai And Singapore, Lily Kong
Making Sustainable Creative/Cultural Space In Shanghai And Singapore, Lily Kong
Research Collection School of Social Sciences
Shanghai and Singapore are two economically vibrant Asian cities that have recently adopted creative/cultural economy strategies. In this article I examine new spatial expressions of cultural and economic interests in the two cities: state-vaunted cultural edifices and organically evolved cultural spaces. I discuss the simultaneous precariousness and sustainability of these spaces, focusing on Shanghai's Grand Theatre and Moganshan Lu and on Singapore's Esplanade-Theatres by the Bay and Wessex Estate. Their cultural sustainability is understood as their ability to support the development of indigenous content and local idioms in artistic work. Their social sustainability is examined in terms of the social …
