Hidden messages: evaluating the effectiveness of code elision in program navigation
(University of Canterbury. Computer Science and Software Engineering., 2003)
Text elision is a user interface technique that aims to improve the efficiency of navigating through information by allowing regions of text to be ‘folded’ into and out of the display. Several researchers have argued that ...
Rate-1/2 component codes for nonbinary turbo codes
(University of Canterbury. Electrical and Computer Engineering, 2005)
The iterative decoding structure and component maximum a posteriori decoders used for decoding binary concatenated codes can be extended to the nonbinary domain. This paper considers turbo codes over nonbinary rings, ...
Real-time optimization of an active filter's performance
(University of Canterbury. Electrical and Computer Engineering., 1994)
Recent advances in power electronics have meant that many loads now draw a distorted current from the power supply. For the same real power consumed, the apparent power for the distorted load is greater than the equivalent ...
AppMonitor: A Tool for Recording User Actions in Unmodified Windows Applications
(University of Canterbury. College of Science.University of Canterbury. Computer Science and Software Engineering.University of Canterbury. Human Interface Technology Laboratory., 2008)
This paper describes AppMonitor, a Microsoft Windows based client-side logging tool that records user actions in unmodified Windows applications. AppMonitor allows researchers to gain insights into many facets of interface ...
Virtual Reality Down Under: VR Research in Oceania
(University of Canterbury. Human Interface Technology Laboratory., 2006)
Oceania encompasses 15 nations and stretches over much of the Pacific Ocean, but only two of these countries are involved in any significant amount of Virtual Reality research; Australia and New Zealand. In this paper ...
Comments Regarding "On the Performance/Complexity Tradeoff in Block Turbo Decoder Design"
(University of Canterbury. Electrical and Computer Engineering, 2009)
In this comment we position the work of Z. Chi, et al, 2004,2001 in terms of the prior literature and note that many of its results are subsumed by previous papers.
Intelligent tutors for all: Constraint-based modeling methodology, systems and authoring
(University of Canterbury. Computer Science and Software Engineering.University of Canterbury. UC Opportunity., 2007)
Intelligent Tutoring Systems (ITS) have revolutionized online education by providing individualized instruction tailored towards each student. Constraint-based tutors model instructional domains at an abstract level, a ...
Refining Phylogenetic Trees Given Additional Data: Algorithms Based on Parsimony
(University of Canterbury. Mathematics and Statistics, 2009)
Given a set X of taxa, a phylogenetic X-tree T that is only partially resolved, and a collection of characters on X, we consider the problem of finding a resolution (refinement) of T that minimizes the parsimony score of ...
Selecting taxa to save or sequence: desirable criteria and a greedy solution
(University of Canterbury. Mathematics and Statistics., 2008)
Three desirable properties for any method of selecting a subset of evolutionary units (EUs) for conservation or for genomic sequencing are discussed. These properties are spread, stability, and applicability. We are motivated ...
A Fast 4x4 Forward Discrete Tchebichef Transform Algorithm
(University of Canterbury. Computer Science and Software Engineering., 2007)
The discrete Tchebichef transform (DTT) is a transform method based on discrete orthogonal Tchebichef polynomials, which have applications recently found in image analysis and compression. This letter introduces a new fast ...
