The AUT Creative Industries Research Institute (CIRI) is a hub which weaves together the many creative strands running through the Faculty of Design and Creative Technologies.
The Pacific Media Centre, one of five foundation research centres of CIRI, produced an extensive archive (2007-2020) of news and current affairs, articles, videos, book chapters and books by the PMC team and its group of associated international researchers. Its directory of peer-reviewed communication and media research abstracts is here: https://pmcarchive.aut.ac.nz/research.html, and the research journal Pacific Journalism Review is at Tuwhera: https://ojs.aut.ac.nz/pacific-journalism-review/

- ItemComputerized sales assistants: the application of computer technology to measure consumer interest - a conceptual framework(California State University, 2008) Shergill, GS; Sarrafzadeh, A; Diegel, O; Shekar, AThis paper describes a computerized intelligent sales assistant that gives sales personnel the ability to allocate their time where it will produce the best results, both for the customer, and for the business. Upon entering the shop, a potential customer has his features scanned and analyzed by the computer and the customer is categorized as a browser, future customer, potential customer or buyer. The customers‟ facial data are also used to retrieve their details, if available, from the shop‟s database, and the data are used to determine whether a human sales assistant is required. The intelligent assistant‟s expression recognition feature would also tell the sales personnel whether or not the customer requires or desires assistance in the first place. The paper also proposes a scenario whereby the system could be used to give online sales systems the ability to automatically tailor the services they offer to the customer based on their facial reactions. While browsing the contents of an e-shop, a customer has his facial expressions scanned and analyzed by the computer and, based on the results, the system can suggest further products that may be of interest to the customer. This, for the customer, can mean being directed to products they have been recognized to be more interested in, resulting in savings in time. The framework described in this paper could also be used for applications such as new product screening, marketing and advertising. This paper describes the theoretical and conceptual framework for such an intelligent sales assistant and discusses the technology used in its implementation.
- ItemCurved layer fused deposition modeling(Sabinet, 2010) Singamneni, S; Diegel, O; Huang, B; Gibson, I; Chowdhury, RCurrent Fused Deposition Modeling (FDM) technologies deposit material as flat layers. The result is a “stair-case” effect on non-vertical or horizontal surfaces, and compromised part strength because of weakness between the laminations. This paper describes a FDM method through which layers of build material are deposited as curved layers following the shape of the part, thus removing the stair-case effect and creating parts that have an even strength distribution over their entire surface. Support material is first deposited as conventional flat layers, and build material is then deposited over the support structure following the curves of the part. The paper discusses a proof of concept of the system, the algorithms used to generate the curve paths for the deposition head, and examines the challenges and possibilities of this technology, including the capability of including composite materials.
- ItemCurved layer fused deposition modeling in conductive polymer additive manufacturing(Trans Tech Publications, 2011) Diegel, O; Singamneni, S; Huang, B; Gibson, IThis paper describes a curved-layer additive manufacturing technology that has the potential to print plastic components with integral conductive polymer electronic circuits. Researchers at AUT University in New Zealand and the National University of Singapore have developed a novel Fused Deposition Modeling (FDM) process in which the layers of material that make up the part are deposited as curved layers instead of the conventional flat layers. This technology opens up possibilities of building curved plastic parts that have conductive electronic tracks and components printed as an integral part of the plastic component, thereby eliminating printed circuit boards and wiring. It is not possible to do this with existing flat-layer additive manufacturing technologies as the continuity of a circuit could be interrupted between the layers. With curved-layer fused deposition modeling (CLFDM) this problem is removed as continuous filaments in 3 dimensions can be produced, allowing for continuous conductive circuits.
- ItemEvaluation of the thermal behaviour of bevelled cutting inserts using a numerical approach(Sage Publications, 2007-11-01) Singamneni, SB; Singh, D; Littlefair, G; Diegel, O; Gupta, OP; Chattopadhyay, ABThe nose geometry of a hard and brittle metal cutting tool is generally modified in order to avoid the premature failure due to fracture under tensile stresses. While most research findings point to a favourable mechanical load pattern, the possible influence of the shape of the geometry on the thermal fields and the consequent changes in the stressed state of the tool seem to have attained less attention. The present work aims at establishing the thermal behaviour of bevelled tools under varying geometrical and process parameters. Data generated from statistically designed experiments and quick-stop chip samples are coupled to conduct numerical investigations using a mixed finite and boundary element solution to obtain the temperature distribution in bevelled carbide inserts. Due consideration is given to the presence of the stagnation zone and its size and shape. While the cutting forces and temperatures increased owing to the blunt shape of the tool, the possible absence of tensile stresses was found to be the likely effect of a more uniform temperature distribution resulting from a significant plastic contact on the principal flank and the consequent flank heat source. The characteristic low-temperature zones close to the nose of the conventional tool are taken over by the stagnation zone in bevelled tools.
- ItemGetting rid of the wires: Curved Layer Fused Deposition Modeling in Conductive Polymer Additive Manufacturing(Trans Tech Publications, 2011) Diegel, O; Singamneni, S; Huang, B; Gibson, IThis paper describes an additive manufacturing technology that has the potential to print plastic components with integral conductive polymer electronic circuits. This could have a major impact in the fields of robotics and mechatronics as it has the potential to allow large wiring looms, often an issue with complex robotic systems, to be printed as an integral part of the products plastic shell. This paper describes the development of a novel Fused Deposition Modeling (FDM) process in which the layers of material that make up the part are deposited as curved layers instead of the conventional flat layers. This opens up possibilities of building curved plastic parts that have conductive electronic tracks and components printed as an integral part of the plastic component, thereby eliminating printed circuit boards and wiring.

- ItemTools for sustainable product design: additive manufacturing(Canadian Center of Science and Education, 2010) Diegel, O; Singamneni, S; Reay, S; Withell, AThe advent of additive manufacturing technologies presents a number of opportunities that have the potential to greatly benefit designers, and contribute to the sustainability of products. Additive manufacturing technologies have removed many of the manufacturing restrictions that may previously have compromised a designer’s ability to make the product they imagined. Products can also be extensively customized to the user thus, once again, potentially increasing their desirability, pleasure and attachment and therefore their longevity. As additive manufacturing technologies evolve, and more new materials become available, and multiple material technologies are further developed, the field of product design has the potential to greatly change. This paper examines how aspects of additive manufacturing, from a sustainable design perspective, could become a useful tool in the arsenal to bring about the sustainable design of consumer products.
