Bayesian models provide a framework for probabilistic modelling of complex datasets. However, many of such models are computationally demanding especially in the presence of large datasets. On the other hand, in sensor network applications, statistical (Bayesian) parameter estimation usually needs distributed algorithms, in which both data and computation are distributed across the nodes of the...

The management on construction projects and organizations is very important. However it is poorly understood considering the declining performance of construction industry. Managing and predicting the work performance of a construction organization tends to be extremely difficult using conventional management approaches. This paper regards construction as a complex system and proposes the use o...

3D reconstruction pipelines using structure-from-motion and multi-view stereo techniques are today able to reconstruct impressive, large-scale geometry models from images but do not yield textured results. Current texture creation methods are unable to handle the complexity and scale of these models. We therefore present the first comprehensive texturing framework for large-scale, real-world 3D...

This issue discusses methods to extract three-dimensional (3D) models from plain images. In particular, the 3D information is obtained from images for which the camera parameters are unknown. The principles underlying such uncalibrated structure-from-motion methods are outlined. First, a short review of 3D acquisition technologies puts such methods in a wider context and highlights their import...

[1] In the fall of both 1999 and 2000, unexpected ‘‘rapid tides’’ occurred along the coast of the Avalon Peninsula of Newfoundland. These rapid tides have been linked to the passing of Tropical Storm Jose (1999) and Tropical Storm Helene (2000) over the Grand Banks. Here we examine the dynamic ocean response to Tropical Storm Helene (2000) using a barotropic shallow water ocean model forced by ...

A one-way nested-grid coastal ocean circulation modeling system was developed for Canadian Atlantic coastal waters based on an operational prototype shelf circulation forecast system known as Dalcoast3 and a high-resolution coastal circulation model developed for Lunenburg Bay (LB) of Nova Scotia. The nested-grid system consists of five relocatable downscaling sub-models, including the outermos...

1 Motivation Orientation of cameras with minimum and redundant information is the rst step in 3D-scene analysis. Compared to image interpretation it looks simple, it seems to be solved in photogrammetry and is expected to be implemented within a few weeks. All experience shows that camera calibration and orientation needs much eeort and the solutions provided in photogrammetric textbooks cannot...

We present a detailed plan to teach Entity-Relationship modeling in an undergraduate course in Database Systems. The course syllabus fulfills the requirements of a first database course in the IS 2002 model curriculum. It is designed to be offered on-line for self-paced learning within the 15 weeks of a regular term. Our goal is to ensure the scope of coverage and the quality of delivery, and a...
