Linear acoustic waves in a nonisothermal atmosphere. II. photospheric resonator model of three-minute umbral oscillations
(IOP Publishing LTD, 2019)The velocity oscillations observed in the chromosphere of sunspot umbrae resemble a resonance in that their power spectra are sharply peaked around a period of about three minutes. In order to describe the resonance that ... -
Towards trainable synthesis for optimized circuit deployment on FPGA
(IEEE, 2018)Field Programmable Gate Arrays (FPGAs) utilize multiple programmable elements and non-programmable blocks. After synthesizing an input Hardware Design Language (HDL) design into a circuit, optimizations are used to discover ... -
Patient-reported quality of life for cataract surgery: prospective validation of the ‘Impact on Life’ and Catquest-9SF questionnaires in New Zealand
(NZMA, 2019)AIMS: The 'Impact on Life' (IoL) questionnaire is used to prioritise publicly funded cataract surgery in New Zealand, however, it has not been formally validated for ophthalmic use. The Catquest-9SF questionnaire is widely ... -
Glycemic-aware metrics and oversampling techniques for predicting blood glucose levels using machine learning.
(2019)Techniques using machine learning for short term blood glucose level prediction in patients with Type 1 Diabetes are investigated. This problem is significant for the development of effective artificial pancreas technology ... -
Managing application-level QoS for IoT stream queries in hazardous outdoor environments
(SciTePress, 2019)While most IoT projects focus on well-controlled environments, this paper focuses on IoT applications in the wild, i.e., rugged outdoor environments. Hazard warnings in outdoor monitoring solutions require reliable pattern ... -
Dastgàh recognition in Iranian music: different features and optimized parameters
(ACM Press, 2019)In this paper we report on the results of utilizing computational analysis to determine the dastgàh, the mode of music in the Iranian classical art music, using spectrogram and chroma features. We contrast the effectiveness ... -
A matter of security, privacy and trust: A study of the principles and values of encryption in New Zealand
(New Zealand Law Foundation and University of Waikato, 2019)Cybersecurity is crucial for ensuring the safety and well-being of the general public, businesses, government, and the country as a whole. New Zealand has a reasonably comprehensive and well-grounded legal regime and ... -
Non-orthogonally transitive G₂ spike solution
(IOP Publishing Ltd, 2015)We generalize the orthogonally transitive (OT) G₂ spike solution to the non-OT G₂ case. This is achieved by applying Geroch's transformation on a Kasner seed. The new solution contains two more parameters than the OT G₂ ... -
State of the art on formal methods for interactive systems
(Springer, 2017)This chapter provides an overview of several formal approaches for the design, specification, and verification of interactive systems. For each approach presented, we describe how they support both modelling and verification ... -
Trends and gaps
(Springer, 2017)This chapter attempts to identify future research directions for formal methods in HCI. It does this using two main approaches. First, we will look at trends within HCI more broadly and the challenges these pose for formal ... -
Case studies
(Springer, 2017)This chapter introduces a set of case studies that are used in the rest of the book. They encompass well known problem domains in Human-Computer Interaction research and provide a practical focus for the approaches presented ... -
Semi-supervised learning using Siamese networks
(Springer, 2019)Neural networks have been successfully used as classification models yielding state-of-the-art results when trained on a large number of labeled samples. These models, however, are more difficult to train successfully for ... -
Robotic kiwifruit harvesting using machine vision, convolutional neural networks, and robotic arms
(Elsevier, 2019)As labour requirements in horticultural become more challenging, automated solutions are becoming an effective approach to maintain productivity and quality. This paper presents the design and performance evaluation of a ... -
Using character-grams to automatically generate pseudowords and how to evaluate them
(Oxford University Press, 2019)This paper provides a practical solution to the problem of generating (good) pseudowords, which are commonly used in vocabulary testing and experimental research in applied linguistics, and introduces an empirically founded ... -
A snapshot of reading, searching, and browsing preferences of tertiary students
(BCS Learning and Development LtdBCS Learning and Development Ltd, 2018)Unanswered questions remain regarding how to design search result pages in library catalogues that offer effective library seeking experiences for users — especially those designed for small screen mobile devices. This ... -
