Accelerating Monte Carlo simulations with an NVIDIA® graphics processor
(Elsevier, 2009)Modern graphics cards, commonly used in desktop computers, have evolved beyond a simple interface between processor and display to incorporate sophisticated calculation engines that can be applied to general purpose ... -
A combined optical, thermal and electrical performance model of a Building Integrated Photovoltaic/Thermal Concentrator (BIPVTC)
(School of Engineering and Advanced Technology, 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 ... -
Defocus restoration for a full-field heterodyne ranger via multiple return separation
(IVCNZ, 2007)Full-field heterodyne time-of-flight range-imagers allow a large number of range measurements to be taken simultaneously across an entire scene; these range measurements may be corrupted due to limited depth of field. We ... -
Development of a multispectral imaging system for apple firmness prediction
(2015)Multispectral imaging has been studied in recent years as a means of assessing fruit firmness. Here we report on the development of a static multispectral imaging system (MSI) that was used to validate the potential of the ... -
The development of a novel large area building integrated solar collector for pool heating
(2010)Unglazed solar collectors have often been used a means of providing low cost heating to swimming pools. However, these systems are typically polymer style “mats” that are laid on top of a roof, often leading to poor ...

Techniques for low coherence pulsed Doppler lidar
(The University of Waikato, 2000)Wind shear and clear air turbulence are atmospheric phenomena that pose a hazard to aircraft and their passengers. In the past, these phenomena have caused injuries and the occasional death. The ability of a lidar system ... -
NIR technologies for high speed fruit grading
(The University of Waikato, 2001)Today’s consumers seek information about food products so they can purchase with confidence, even if it translates to higher priced items. It is the aim of this thesis to improve the instruments available for the prediction ... -
Doppler velocimetry lidar with amplified reference beam storage loop
(The University of Waikato, 2003)Wind shear and clear air turbulence are phenomena in which wind speeds can change rapidly presenting a threat to aircraft and their passengers. Lidar is a proven technique for wind speed measurement but remains a research ... -
Investigating aquaphotomics for fruit quality assessment
(The University of Waikato, 2020)The methods of aquaphotomics were explored for internal fruit quality assessment, such as dry matter (DM) and soluble solid content (SSC) measurement using near infrared spectroscopy (NIRS). Fruits like apple and kiwifruit ... -
Spatially resolved spectroscopy for detecting firmness and internal disorders of horticultural products
(The University of Waikato, 2018)Nondestructive detection of firmness and internal disorders are critical for New Zealand’s horticultural industry. Soft and internally defective products can result both in loss of revenue and the supplier’s reputation for ...
