#### Outage probability of cooperative relay networks in Nakagami-m fading channels

(University of Canterbury. Electrical and Computer Engineering., 2006)

It is well known that the cooperation among nodes
can improve the performance of a wireless network. In this letter
we analyze the outage probability behaviour of a relay network
in Nakagami-m fading channels. A closed-form ...

#### Estimating the relative order of speciation or coalescence events on a given phylogeny

(University of Canterbury. Mathematics and Statistics., 2006)

The reconstruction of large phylogenetic trees from data that violates clocklike evolution (or as a supertree constructed
from any m input trees) raises a difficult question for biologists–how can one assign relative dates ...

#### Neighbor-Joining revealed

(University of Canterbury. Mathematics and Statistics., 2006)

It is nearly 20 years since the landmark paper (Saitou and Nei 1987) in Molecular Biology and Evolution introducing Neighbor-Joining (NJ). The method has become the most widely used method for building phylogenetic trees ...

#### Unicyclic Networks: Compatibility and Enumeration

(University of Canterbury. Mathematics and Statistics., 2006)

Graphs obtained from a binary leaf labelled (‘phylogenetic’)
tree by adding an edge so as to introduce a cycle provide a
useful representation of hybrid evolution in molecular evolutionary biology.
This class of graphs ...

#### Elation Laguerre planes of order 16 are ovoidal

(University of Canterbury. Mathematics and Statistics., 2006)

We conduct a computer search for elation Laguerre planes of order 16
and show that each such plane is ovoidal. The search results also
confirm the numbers of hyperovals through certain points in the dual
translation ...

#### Comparison of various estimators of Hurst parameter in simulated FGN

(Department of Computer Science and Software Engineering, University of CanterburyUniversity of Canterbury. Computer Science and Software Engineering, 2006)

The Hurst parameter is the simplest numerical characteristic of self-similar long-range dependent stochastic processes. Such processes have been identified in many natural and man-made systems. In particular, since they ...

#### Stochastic insulin sensitivity models for tight glycaemic control

(University of Canterbury. Mathematics and Statistics.University of Canterbury. Mechanical Engineering., 2006)

Hyperglycaemia is prevalent in critical care, and tight control reduces mortality.
Targeted glycaemic control can be achieved by frequent fitting and prediction of a
modelled insulin sensitivity index, SI. However, this ...

#### Simple Expressions for the Correlation between Fading Channel Error Rates

(University of Canterbury. Electrical and Computer Engineering., 2006)

Given digital transmission over two correlated Rician fading channels, we present a readily calculable expression for a tight approximation to the correlation between the probabilities of symbol error on each channel. For ...

#### New Properties of Complex Noncentral Quadratic Forms and Bounds on MIMO Mutual Information

(University of Canterbury. Electrical and Computer Engineering., 2006)

This paper presents new statistical properties of complex noncentral matrix-variate quadratic forms. In contrast to previous results, the expressions do not involve infinite sums over partitions, or matrix-variate polynomials, ...

#### Does Reduced Uncertainty Mean Greater Certainty?

(Project Management Instutute of New Zealand (PMINZ)University of Canterbury. Mechanical Engineering, 2006)

This paper explores how uncertainty in duration estimates is handled, with the subject area
being new product development. In many projects simple deterministic estimates of nominal
task duration may be sufficient (for ...
