Bagging Regularizes
(2002-03-01)
Intuitively, we expect that averaging --- or bagging --- different regressors with low correlation should smooth their behavior and be somewhat similar to regularization. In this note we make this intuition precise. ...
External prestressed carbon fiber-reinforced polymer straps for shear enhancement of concrete
(American Society of Civil EngineersJournal of Composites for Construction (ASCE), 2002)
The use of fiber-reinforced polymers (FRPs) for the strengthening and repair of existing concrete structures is a field with tremendous potential. The materials are very durable and, hence, ideally suited for use as external ...
On the performance of base-isolated buildings: a generic model
(University of CambridgeDepartment of Engineering, 2002-02-12)
Ground-borne vibration has existed ever since the development of urban road and rail networks. Vibration generated by the moving traffic propagates through the ground and into buildings, resulting in unacceptable levels ...
Collapse of masonry structures
(University of CambridgeDepartment of EngineeringKing's College, 2002-07-16)
TIlls dissertation examines the collapse of masonry structures in response to large
support displacements and horizontal ground accelerations. There are two main classes of masonry structure: arches that thrust, and ...
Quality control tools for interactive rendering of 3D triangle meshes
(2002)
In this dissertation we explore methods of quality control of untextured polygonal models. The tools presented build, evaluate and improve on the field of multiresolution analysis through decimation. We evaluate the quality ...
Recursively invoking Linnaeus: A Taxonomy for Naming Systems
(2002-03-01)
Naming is a central element of a distributed or network system design. Appropriate design choices are central. This paper explores a taxonomy of naming systems, and engineering tradeoffs as an aid to the namespace designer. ...
Garbage collection of the PLAVA object store
(2002)
This research investigates the implementation of suitable garbage collection schemes for a persistent store. The store that formed the basis for these experiments was the one developed for a Java Virtual Machine known as ...
Using programming tools in virtual environments
(2002)
Presence is the sense of being in the computer-generated environment. It is regarded as the key to understanding the success of a virtual environment. In this research we focus on desktop virtual environment authoring ...
Model-based segmentation of CT Images
(University of Cape Town, 2002)
This paper presents preliminary work on the segmentation of Computed Tomography data using a model-based approach.
Conventional image processing of CT data is aimed at the production of simple iso-surfaces for surgical ...
The spatial learning method : facilitation of learning through the use of cognitive mapping in virtual reality
(2002)
When moving through an environment, people unconsciously build up a mental image, or cognitive map, of that environment. When later planning a trip or giving directions to someone else, they can mentally walk through the ...
