(Electronics New Zealand, AUT University, 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 ... -
(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 ... -
(CRDM Ltd; 2011)It has been speculated that, in the near future, additive manufacturing will begin to have a marked effect on how we order and manufacture products. When one examines some of the implications of AM more closely, it can be ... -
(The Royal Society London, AUT University; 2003)A kepstrum (or complex-cepstrum) approach to minimum-phase Wiener filtering of stationary scalar processes is proposed and solved for the case of signal plus coloured noise, where the noise possibly includes a white-noise ... -
(Universiti Tun Hussein Onn Malaysia; 2012)The use of energy in buildings is an ongoing concern, not only in NZ but worldwide. This concern has led to significant growth in the use of solar energy to provide heating and electricity generation. This paper presents ... -
(AUT University, IAAMSAD; 2004)This paper addresses the issue of position/force tracking for a constrained robot within the framework of impedance control. An adaptive controller is developed in which a varying desired impedance is adaptively tuned with ... -
(AUT University; 2011)With increasing pressure being placed on traditional energy sources, both in terms of supply and also regulatory, there is an increasing need to explore alternative generation technologies. In global terms, solar energy ... -
(University of Rome “La Sapienza”, AUT University, International Stirling Engine Conference (ISEC); 2003)Although Stirling heat-pumps and refrigerators offer the possibility of environmentally-friendly operation by using air as the refrigerant, the Coefficient of Performance (COP) of low-cost Stirling systems is only about ... -
(AUT University, University of Sydney; 2011)In many highly glazed buildings, the thermal comfort of the occupants will tend to be related to the incoming solar energy and the solar heat gain coefficient of the glazing. Many real buildings tend to be deep relative ... -
(AUT University, Institute of Mathematics ASCR; 1987)Several theories of discrete-time optimal filtering are in current use but the relationships between these theories is not always appreciated. By using a slightly modified form of the Wiener theory, a unification of the ... -
(Springer Verlag (Germany) (for Birkhäuser Boston), AUT University; 2001)A closed-loop servo approach is applied to the problem of controlling and estimating variance in nonstationary signals. The new circuit closely resembles, but is not the same as, automatic gain control, which is common in ... -
(World Academy of Science, Engineering and Technology (WASET), AUT University; 2007)A combined three-microphone voice activity detector (VAD) and noise-canceling system is studied to enhance speech recognition in an automobile environment. A previous experiment clearly shows the ability of the composite ... -
(AUT University; 2011)Crosstalk resistant adaptive noise cancellation (CTRANC) is a method of separat-ing convolutively mixed sources where little a priori information is known about the system. Possible areas of application for such an algorithm ... -
(AUT University; 2009)The aim of this paper is to explore and recommend a rational basis for setting up a retention regime for a given project. Despite a century of practice, there is no theory to provide guidance yet. Using insights gained ... -
(Cryogenic Society of America, AUT University; 2012)Industrial Research Ltd has developed a unique diaphragm-based pressure wave generator technology for employment in pulse tube and Stirling cryocoolers. The system uses a pair of metal diaphragms to separate the clean ... -
(IOP Publishing, AUT University; 2012)The principal aim of this work was to characterize deep silicon etching at sample temperatures well-below room temperature, using SF6/O2 inductively coupled plasma (ICP) for micro-electro-mechanical systems (MEMS) applications. ...
-
(Centre for Continuing Education The University of Auckland; 2012)Glazed flat plate solar collectors offer a simple and cost effective approach to heating water. However, on clear nights solar collectors can transfer a significant amount of heat to the atmosphere by radiation. In areas ...
-
(AUT University, Elsevier; 2011)Nasal morphology plays an important functional role in the maintenance of upper airway health. Identification of functional regions, based on morphological attributes, assists in correlating location to primary purpose. ... -
(Taylor & Francis, AUT University; 2012)In many highly glazed buildings, the thermal comfort of the occupants will tend to be related to the incoming solar energy and the heat transfer behaviour of the glazing. In this study, several glazing systems were designed ... -
(United States National Library of Medicine, AUT University, IEEE; 2011)In recent years, there has been a rapid growth in patient monitoring and medical data analysis using decision support systems, smart alarm monitoring, expert systems and many other computer aided protocols. The main goal ...
