A cellular automaton framework for within-field vineyard variance and grape production simulation
(Institute of Electrical and Electronics Engineers (IEEE), 2011)Winegrowers for generations know it all too well that grapes harvested from different areas within a vineyard will produce wines of different flavours, mainly due to within-field variance in vine vigour caused by environmental ... -
A closed-form exact solution for pricing variance swaps with stochastic volatility
(Wiley-Blackwell, 2011)In this paper, we present a highly efficient approach to price variance swaps with discrete sampling times. We have found a closed-form exact solution for the partial differential equation (PDE) system based on the Heston’s ... -
A collaborative learning trial between New Zealand and Sweden - using Lotus Notes Domino in teaching the concepts of Human Computer Interaction
(ACM, 1999)This paper reports the results of a collaborative learning exercise between students at Auckland Institute of Technology and Uppsala University. The exercise was conducted using both a Lotus Notes Domino collaborative ... -
A combined optical, thermal and electrical performance model of a Building Integrated Photovoltaic/Thermal Concentrator (BIPVTC)
(Electronics New Zealand/Massey University, 2011)The electrical output of concentrating photovoltaic devices is significantly affected by the temperature of the photovoltaic cells. The ability to actively cool photovoltaic cells under concentrated radiation allows their ... -
A Comparative Analysis of Opinion Mining and Sentiment Classification in Non-english Languages
(IEEE, 2013)In the past decade many opinion mining and sentiment classification studies have been carried out for opinions in English. However, the amount of work done for non-English text opinions is very limited.In this review, we ... -
A comparison of computational techniques of the key properties of Markov Chains
(Australia and New Zealand Industrial and Applied Mathematics (ANZIAM), 2015)The presenter has recently been exploring the accurate computation of the stationary distribution for finite Markov chains based upon the Grassman, Taksar and Heyman (GTH) algorithm ([1]) with further extensions of this ... -
A comparison of nonlinear control performance assessment techniques for nonlinear processes
(Wiley-Blackwell, 2012)Assessing the quality of industrial control loops is an important auditing task for the control engineer. However, there are complications when considering the ubiquitous nonlinearities present in many industrial control ... -
A comparison of teacher and lecturer perspectives on the transition from secondary to tertiary mathematics education
(Taylor & Francis, 2009)The transition from school to tertiary study of mathematics comes under increasing scrutiny in research. This article reports on some findings from a project analysing the transition from secondary to tertiary education ... -
A computational theory of human perceptual mapping
(Cognitive Science Society, 2011)This paper presents a new computational theory of how humans integrate successive views to form a perceptual map. Traditionally, this problem has been thought of as a straightforward integration problem whereby position ... -
A conceptual framework to evaluate suppliers for building infrastructure in the Malaysian electricity supply industry
(Universiti Teknologi Malaysia (UTM), 2012)In the current competitive business environment the relationship between buyers and suppliers is no longer antagonistic. Emphasis has shifted to the forging of partnerships that benefits all parties in any business setting. ... -
A control system for an unmanned micro aerial vehicle
(AUT University, 2011)This paper presents the development of a PCbased control system for an unmanned micro aerial vehicle (UAV) that has been converted from a helicopter model. The hand-controller of the helicopter model is modified to be a ... -
A controlled Natural Language Interface to Class Models
(SciTePress, 2011)The available approaches for automatically generating class models from natural language (NL) software requirements specifications (SRS) exhibit less accuracy due to informal nature of NL such as English. In the automated ... -
A cost-effective electric vehicle charging method designed for residential homes with renewable energy
(Walter de Gruyter GmbH, 2015)Most of the electrical infrastructure in use around the world today is decades old, and may be illsuited to widespread proliferation of personal Electric Vehicles (EVs) whose charging requirements will place increasing ... -
A cost-effective EV charging method designed for residential homes with renewable energy
(IEEE, 2014)This paper presents a smart and cost effective EV (Electric Vehicle) charging methodology for residential dwellings which have renewable energy sources. The proposed method has many benefits, including reducing peak pressure ... -
A course design for flexible learning
(AUT University, 2001)Interpreting innovation as “combining information from diverse sources into new knowledge” this paper looks into the advantages which information and communications technology development can bring into the design of a ... -
A critical evaluation of failure in a nearshore outsourcing project (what dilemma analysis can tell us)
(IEEE, 2013)Global Software Engineering (GSE) research contains few examples consciously applying what Glass and colleagues have termed an ‘evaluative-critical’ approach. In this study we apply dilemma analysis to conduct a critical ... -
A cross layer framework for WLANs: joint radio propagation and MAC protocol
(IEEE, 2010)This paper proposes a cross-layer design (CLD) framework called channel-aware buffer unit multiple access (C-BUMA) for improving wireless local area network (WLAN) performance. In the framework, the radio propagation (i.e. ... -
A cyber-icebreaker for an effective virtual group?
(ACM, 2001)This paper reports selected results from the most recent of a series of international collaborative trials between students at Auckland University of Technology and Uppsala University. The trials require students to work ... -
A data mining approach to analysing airborne wood particulate concentration and atmospheric data
(International Conference on Information Technology and Multimedia at UNITEN (ICIMu 2014), 2014)Exposure to airborne wood (hard and soft) dust can lead to a number of diseases, such as asthma, emphysema, bronchitis and upper respiratory tract cancers, lately even proven to be linked to elevated risks for chromosomal ... -
