Detecting Faces in Impoverished Images
(2001-11-05)
The ability to detect faces in images is of critical ecological significance. It is a pre-requisite for other important face perception tasks such as person identification, gender classification and affect analysis. Here ...
Perceiving Illumination Inconsistencies in Scenes
(2001-11-05)
The human visual system is adept at detecting and encoding statistical regularities in its spatio-temporal environment. Here we report an unexpected failure of this ability in the context of perceiving inconsistencies in ...
Improving Multiclass Text Classification with the Support Vector Machine
(2001-10-16)
We compare Naive Bayes and Support Vector Machines on the task of multiclass text classification. Using a variety of approaches to combine the underlying binary classifiers, we find that SVMs substantially outperform Naive ...
An interface element based on the partition of unity
(Delft University of Technology, 2001)
An alternative interface finite element is developed. By using the partition of unity property of finite element shape functions, discontinuous shape functions are added to the standard finite element basis. The interface ...
Fibre-reinforced polymers in reinforced and prestressed concrete applications: moving forward
(John Wiley & Sons, Ltd.Progress in Structural Engineering and Materials, 2001)
Recent developments in the use of fibre-reinforced polymers (FRPs) in reinforced and prestressed concrete applications are reviewed. The influence of FRP material properties on the design of concrete structures is considered ...
Signal separation of musical instruments: simulation-based methods for musical signal decomposition and transcription
(University of CambridgeDepartment of EngineeringPembroke College, 2001-05-29)
This thesis presents techniques for the modelling of musical signals, with particular regard to monophonic and polyphonic pitch estimation. Musical signals are modelled as a set of notes, each comprising of a set of ...
Visualisation of ATM network connectivity and topology
(2001)
ATM and dynamic reconfiguration allow for rapid changes in a virtual path network depending on traffic load and future demands. This technology improves the utilisation, lowers the call blocking probability and increases ...
Investigating cost effective communication alternatives for geographically hostile regions
(2001)
The lack of communication facilities in developing countries is a constraint to social, political and economic empowerment of the people. However, advances in technology promise to deliver voice, video and data communication ...
Facilitating the modelling and automated analysis of cryptographic protocols
(2001)
Multi-dimensional security protocol engineering is effective for creating cryptographic protocols since it encompasses a variety of design, analysis and deployment techniques, thereby providing a higher level of confidence ...
Epistemology as the basis for a corporate memory model
(2001)
Epistemology is the philosophical study of knowledge; it attempts to understand which beliefs a person can claim to know. This thesis discusses how theories found in epistemology can be used to understand what knowledge ...
