The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which f...

In this paper we address the problem of time based activity inference in unsupervised manner for an area under surveillance. We use a Latent Dirichlet Allocation based model that captures the activities and how they change over time. We use agglomerative clustering on optical flow vectors to code direction and spatial information. In this model each activity is associated with not only a mixtur...

The active and skilful use of tools has been claimed to lead to the "extension" of the visual receptive fields of single neurons representing peripersonal space--the visual space immediately surrounding one's body parts. While this hypothesis provides an attractive and potentially powerful explanation for one neural basis of tool-use behaviours in human and nonhuman primates, a number of compet...

Modeling land allocation for different land uses at regional level is a multi-dimensional problem, as it is influenced by spatial, temporal and dynamics of environmental and socio-economic factors in the complex process of land use change. It is therefore a challenge to develop a proper model that can handle these complexities. In this context, a new model has been conceptualized and developed....

In the last 20 years, both public and private expenditures on resource conservation and environmental protection have increased dramatically. However, there are numerous technical and political barriers to the efficient use of conservation funds. This paper discusses some of these barriers and approaches to overcoming them. It argues that ecosystem complexities such as threshold effects, ecosys...

Managing stressors is essential for optimizing pig growth performance. To determine the effects of temperature and space allocation on growth performance and carcass characteristics, pigs were housed within their thermoneutral zone, at 23.9 degrees C, or above their thermoneutral zone, at 32.2 degrees C, and were provided either 0.66 or 0.93 m(2)/pig for the final 35 d of the grow-finish period...

We present the Hierarchical Latent Dirichlet Allocation (hLDA) for organizing a collection of scene images into a hierarchy in unsupervised fashion. The bag of visual words model with spatial pyramids is adpated to the hLDA where the spatial generality is used as a prior of assignments of topics to visual words. Both depth and width of the tree are unbounded and inferred by training data using ...
