    The evolution of construction industry towards sustainability highlighted the absolute necessity to inspect sustainable performances throughout the post-construction building lifecycle. Correspondingly, application of relevant building management systems (BMS) to achieve this goal is mandatory (Ippolito, Riva Sanseverino, & Zizzo, 2014). In addition, conventional post-construction building inspection methods are outdated and less effective. Therefore; this research aims to propose specific utilization of BIM during building maintenance for the consequential post-construction energy efficiency. Contemporarily, Building Information Modelling (BIM) is considered as a leading technology capable of being utilized in Architecture, Engineering, Construction (AEC) practices highlighting its critical role in enhancing the effectiveness of project delivery from conceptual initiation to eventualization and even post-construction maintenance (Ding, Zhou, & Akinci, 2014; Volk, Stengel, & Schultmann, 2014). Alternatively, despite the recent presentation of BIM to the AEC industry, it has widely emerged to an undisputedly contributive technology towards advancement of AEC implementations. Furthermore, BIM’s capability of nD project integrations has prominently highlighted its potential effectiveness while being accurately incorporated with sustainable performances (Farr, Piroozfar, & Robinson, 2014). Moreover, researchers have highlighted that information gathering and modelling through BIM can reduce respective building energy consumptions (Lawrence et al., 2012). The remarkable proportion of global energy consumption by the construction industry has fundamentally driven the concentration on decreasing the building energy consumption via amplified sensor data and improved computational support for building controls (Klein et al., 2012). Subsequently, it is vital to balance the maximization of building energy efficiency and users’ desired level of comfort while employing an efficient BMS for sustainable maintenance of facility operations overstressing the implication of post-construction building inspection. Researchers have overstressed that application of an efficient Facility Maintenance and Management systems (FMM) enables executives to detect problems primarily and sustain the facility more effectively (Chen, Hou, & Wang, 2013). On the other hand, the conventional inspection method of progress tracking practice would solely rely on manual visual assessments and periodical respective reports. This progress consisted of logs and checklists manually prepared to indicate the project’s level of adaptability with the required milestones and specifications (Bosché, Ahmed, Turkan, Haas, & Haas, 2014). Effectiveness and accuracy of the corresponding inspection progress would have been affected based on the individual’s personal judgment and observational skills. Additionally, high probability of inaccurate manual building inspections plus the lack of real-time input of dynamic factors urges development of automated BMS. Therefore, Building Information Modelling (BIM) plays a key role towards automation in construction and corresponding management systems. However, adequate skills; competence and enthusiasm of construction role-players and contractors is a significantly important issue towards future success of such propositions (Miettinen & Paavola, 2014). Additionally, the progression of AEC building delivery includes design, construction, contracting and maintenance. This complex process, engaging multi-layer and multi-domain information storage and exchange, necessitates integrative contributions from versatile and incorporative professional teams thus; competent information sharing among players is a critical factor towards success therefore; a proposed BIM system capable of resolving AEC interoperability complications would remarkably enhance the overall project output and respectively the building energy efficiency throughout its lifecycle (Dong, O'Neill, & Li, 2014). Despite the nD capability of BIM enabling its potential practice during versatile building lifecycle phases, designers-contractors focused primarily on the application of BIM during design-construction management stages. Furthermore, positive prospects of BIM’s potential to be applied throughout the post-construction energy efficiency enhancements can be augmented while highlighting the conceivable successful utilization of BIM during corrective building maintenance management concerns compared to preventive concerns (Motawa & Almarshad, 2013). Moreover, integration of knowledge management systems empowering handling and sharing of respective building maintenance information over the building lifecycle is an inevitable essential during post-construction sustainable performances. Harmoniously, contemporary sustainable developments incorporate advancement of exploiting the aforementioned practices. Congruently, focusing on the building energy efficiency, this article suggests engagement of an Integrated Knowledge-based Building Management System using nD BIM applications (BIM-IKBMS) during the post-construction building lifecycle to advance the implementation of sustainable building performances.

    Marshall, S; Archibald, Thomas

    Conference item
    Auckland University of Technology

    Increasing legislative and societal pressures are requiring manufacturers to operate more sustainably and to take responsibility for the fate of their goods after they have been used by consumers. This paper models a hybrid system in which new goods are produced and used goods are remanufactured. Newly produced goods and remanufactured goods are sold on separate markets, but can also act substitutes for each other. A semi-Markov Decision Process formulation of this problem is presented and is used to obtain an optimal policy, which specifies production, recovery and substitution decisions. The model is used explore the properties of this hybrid remanufacturing system, and in particular, the managerial implications associated with upward and downward substitution strategies are investigated.

  • A multi-strategy approach for location mining in Tweets: AUT NLP Group entry for ALTA-2014 shared task

    Nand, P; Perera, R; Lingmin, H

    Conference item
    Auckland University of Technology

    This paper describes the strategy and the results of a location mining system used for the ALTA-2014 shared task competition. The task required the participants to identify the location mentions in 1003 Twitter test messages given a separate annotated training set of 2000 messages. We present an architecture that uses a basic named entity recognizer in conjunction with various rule-based modules and knowledge infusion to achieve an average F score of 0.747 which won the second place in the competition. We used the pre-trained Stanford NER which gives us an F score of 0.532 and used an ensemble of other techniques to reach the 0.747 value. The other major source of location resolver was the DBpedia location list which was used to identify a large percentage of locations with an individual F-score of 0.935

    Auckland University of Technology

    Disaster management and disaster medicine are well-established disciplines for responding to disasters and providing care for individuals whose health and wellbeing has been affected. However, these disciplines have different origins, development, and priorities so that communication and coordination across them during disasters is often lacking, leading to delayed, sub-standard, inappropriate or even unavailable care. Moreover, neither discipline exploits the new range of ehealth technologies such as the electronic health record or telehealth and mobile health that are revolutionizing non-disaster healthcare. We need a new paradigm that applies information and e-health technologies to improve disaster health planning and response. This paper describes the initial stages of a project to develop such a paradigm by scoping and developing the area of disaster e-health.

  • Equal partners? Improving the integration between DSpace and Symplectic Elements

    Murdoch, C; Miller, K; Schweer, A

    Conference item
    Auckland University of Technology

    While self-submission by academics was regarded as the ideal way to add content to Open Repositories in the early days of such systems, the reality today is that many institutional repositories obtain their content automatically from integration with research management systems. The institutional DSpace repositories at Auckland University of Technology (AUT) and at the University of Waikato (UoW) were integrated with Symplectic Elements in 2010 (AUT) and in 2014 (UoW). Initial experiences at AUT suggested a mismatch between the interaction options offered to users of Symplectic Elements on one hand and the actions available to repository managers via the DSpace review workflow functionality on the other hand. Our presentation explores these mismatches and their negative effects on the repository as well as on the user experience. We then present the changes we made to the DSpace review workflow to improve the integration. We hope that our experiences will contribute to an improvement in the integration between repository software and research management systems.

  • Luxury or necessity? Enhancing bibliographic records at The University of Auckland Library

    Mincic-Obradovic, Ksenija (2005)

    Conference item
    The University of Auckland Library

    The local catalogue is supposed to be most attuned to the needs of the local user, but how do we know that what cataloguers consider as valuable information really answers the users’ needs? Lately, issues of retrieval and usefulness of data elements in bibliographic records have caused some concerns. New and constantly changing environments require current cataloguing conventions and MARC record structures to be re-examined. There has also been increasing interest in enhancing bibliographic records with additional content-bearing information. In the University of Auckland Library much work has been done over the last few years on improving access to our monograph collections. To find ways to add value to bibliographic records, cataloguers have to be critical in their analysis and able to improve upon the information provided in bibliographic records provided by external sources. This paper will discuss the parameters we had to find, explain how we decided which elements of data are critical for retrieving material from different collections, and how we examined what effect this will have on our catalogue. It will also describe some of the bibliographic enhancements we have done (additional subject headings; addition of Tables of Contents data; authorities) and how they improved access in bibliographic retrieval.

  • Are dairy heifers achieving liveweight targets?

    McNaughton, LR; Lopdell, Thomas (2012-07)

    Conference item
    The University of Auckland Library

    The reproductive performance of the national dairy herd has declined (Harris et al. 2006). Heifer rearing is one of eight "ingredients" for achieving good reproductive performance identified by the InCalf project (Burke et al. 2007). Many New Zealand dairy farmers graze their heifers on a run-off or pay a grazier to grow the heifers, with heifers commonly leaving the dairy farm at weaning, or nine months of age and returning at around 22 months of age.

  • Effect of sub-clinical uterine infection on plasma amino acid concentrations in early lactation dairy cows

    Lopdell, Thomas; Berg, MC; Green, MP; Back, PJ (2011)

    Conference item
    The University of Auckland Library

    This study examined the effect of sub-clinical endometritis (scEndo) in early lactation on plasma amino acid (AA) concentrations of dairy cattle (n = 46). On D21 and D42 postpartum cows were classified as having scEndo or Clean based on uterine cytology; >18% polymorphonuclear (PMN) cells amongst uterine nucleated cells. On D21 and D42, 35% and 7% of cows respectively were classified as having scEndo, with a large proportion of scEndo cows having self-resolved the infection by D42. Plasma serine concentrations were higher (P <0.05) irrespective of uterine health. However, scEndo is associated with an increase in plasma serine and a decrease in the concentration of several AA when a uterine infection is resolved.

  • Effect of resolving a sub-clinical uterine infection on plasma and follicular fluid steroid concentrations in early lactation dairy cows

    Lopdell, Thomas; Berg, MC; Green, MP; Back, PJ (2012)

    Conference item
    The University of Auckland Library

    Sub-clinical endometritis (scEndo) in early lactation affects ovarian follicle dynamics, delays a return to cyclicity, with changes in plasma and follicular fluid (FF) amino acid concentrations around the time of rebreeding. This study examined the effect of resolving scEndo in early lactation on plasma and FF oestrogen, progestagen, androgen and corticosteroid concentrations at the time of rebreeding in 46 dairy cattle. On D42 postpartum, cows were classified as having scEndo, clean or having resolved scEndo cased on uterine cytology on D21 of > 18% polymorphonuclear (PMN) cells amongst uterine nucleated cells. On D42 and D63 follicular and plasma samples were collected and steroid concentrations analysed. On D21 and D42, 35% and 7% of cows respectively were classified as having scEndo, with 81% of scEndo cows having self-resolved the infection by D42. In those cows that resolved scEndo, none of the plasma or FF steroid concentrations changed between D42 and D63, except for plasma progesterone (P = 0.08). Using a low (4%PMN) threshold to classify scEndo did not identify any significant changes in steroid concentrations. In contrast to previously described changes in plasma and FF amino acid concentrations, there were no significant effects on steroid concentrations when cows self-resolved a sub-clinical uterine infection.

  • Effect of heifer live weight on calving pattern and milk production

    Lopdell, Thomas; McNaughton, LR (2013)

    Conference item
    The University of Auckland Library

    Many heifers on New Zealand dairy farms fail to reach their target live weight. This failure leads to lost milk production and poorer reproductive performance. This study investigated effects of breed and region on heifer live weight and also effects of pre-calving heifer live weight (18–21 months) on milk production. Less Friesian heifers reached their target live weight than Jerseys, or Crossbreds (85.3 versus 89.3 versus 88.1%; P <0.001). In heifers with a live weight record between 18 and 21 months of age, every 1% increase in the percentage of target live weight attainedwas associated with an increase in milk volume of 23 ± 0.6 litres in the first lactation and 24 ± 0.9 litres inthe second lactation. Further work is required on the economics of feeding heifers to achieve their target live weight.

  • Automatic reading of Kamars for heat detection in dairy herds

    Hempstalk, K; Harris, BL; Lopdell, Thomas (2010)

    Conference item
    The University of Auckland Library

    Most existing heat detection systems for dairy cattle are labour-intensive requiring manual inspection of every animal to maximise submission rates. Our solution is to automate heat detection using Kamar HeatMount Detectors and a camera-based recognition system. The goal of our system is to obtain 99% sensitivity and specificity, ensuring that cows that are on heat are rarely missed and over-drafts are kept to a minimum. Trials of various camera prototypes have been undertaken over the past three years, most recently during the artificial breeding period in the Spring of 2009. Over 70,000 images from four farms were taken during the latest trials; these photographs were used to assess the system. When considering photo observations, the fully automated system had an error rate less than 1% across all sites in the latest trial, and reaches our goal of 99% sensitivity and specificity.

  • Improving outcomes for Pasifika students in an academic writing course.

    Matheson, Neil (2013-05-01)

    Conference item
    The University of Auckland Library

    With assessment at the tertiary level still based largely on writing output, the ability to write well is a decisive factor in academic success. This is one reason behind the popularity of an academic writing course at a New Zealand university. Arts faculty targeted admission programme requirements and English language diagnostic recommendations have increased enrolments in this course, but disproportionately poor outcomes for Pasifika students indicate the course may be acting more as a barrier than the intended step to academic success for this group. This paper describes a project undertaken to identify and address immediate issues contributing to such outcomes for Pasifika students. Steps taken include finding out more about the students, closer collaboration between support and academic staff, adaptation of course content, assessment processes and classroom practice, and a greater focus on student engagement throughout the course. Interim results of this project in its first semester of operation will be reported.

  • More dairy heifers are achieving liveweight targets

    Handcock, RC; Lopdell, Thomas; McNaughton, LR (2016)

    Conference item
    The University of Auckland Library

    Dairy heifers should reach industry liveweight targets that are set to ensure heifers achieve good reproductive performance and milk production. The aim of this study was to determine if more dairy heifers born between the 2011-12 and 2014-15 dairy seasons (current) in New Zealand are achieving liveweight targets since a study on heifers born between the 2006-07 and 2010-11 dairy seasons (historic). In all age groups the mean live weight of current heifers was heavier than that of historic heifers. There were also a greater percentage of the current heifers at or above their target live weight compared with the historic heifers (P<0.001), suggesting that the rearing of dairy heifers has improved. The greatest improvement was seen at 15 months of age (mating) when 25% of historic heifers were at or above target compared with 56% of current heifers. Despite the improvement, 44% of current heifers were below target at mating and 65% were below target pre-calving (22 months of age). At 22 months of age, current heifers were on average nearly 42 kg below target live weight. By failing to achieve targets near calving, farmers are not capturing potential milk production benefits.
