Intelligent energy management for plug-in hybrid electric vehicles : the role of ITS infrastructure in vehicle electrification

The desire to reduce carbon emissions due to transportation sources has led over the past decade to the development of new propulsion technologies, focused on vehicle electrification (including hybrid, plug-in hybrid and battery electric vehicles). These propulsion technologies, along with advances in telecommunication and computing power, have the potential of making passenger and commercial vehicles more energy efficient and environment friendly. In particular, energy management algorithms are an integral part of plug-in vehicles and are very important for achieving the performance benefits. The optimal performance of energy management algorithms depends strongly on the ability to forecast energy demand from the vehicle. Information available about environment (temperature, humidity, wind, road grade, etc.) and traffic (traffic density, traffic lights, etc.), is very important in operating a vehicle at optimal efficiency. This article outlines some current technologies that can help achieving this optimum efficiency goal. In addition to information available from telematic and geographical information systems, knowledge of projected vehicle charging demand on the power grid is necessary to build an intelligent energy management controller for future plug-in hybrid and electric vehicles. The impact of charging millions of vehicles from the power grid could be significant, in the form of increased loading of power plants, transmission and distribution lines, emissions and economics (information are given and discussed for the US case). Therefore, this effect should be considered in an intelligent way by controlling/scheduling the charging through a communication based distributed control.

Photochromic fabrics with improved optical performance

In this PhD project, the photostability and colour depth of photochromic fabrics prepared by a hybrid silica coating were improved and the relationship between the pore structure of the silica coatings and the photochromic properties of the coated fabrics was investigated.

University entrepreneurship : context, process and performance

This project embraced empirical work that studied existing research commercialization systems (RCS) at both first tier and second tier universities, found them flawed and produced an enhanced framework that is definitely applicable to second tier universities (the vast majority) and possibly applicable to first tier universities as well.

Pre-visualization techniques with live lensing system enhances workflow for interactive performance creation.

Vincs & Divers, with dancer Steph Hutchinson, present a new system for real-time previsualization in Motion Builder that enables choreographers and artists making interactive 3D work to make on-the-fly lensing decisions. Using motion capture to drive a ‘character’ created from a cloth simulation in real time, the presentation highlights the advantage of live lensing for interactive work-flow in creating 3D dance visualizations. This work forms part of Vincs’ ARC Discovery project ‘Building innovative capacity in Australian dance through new visualization technologies’ (DP120101695).

A network analysis of IT governance practices : a case study of an IT centralisation project

Information technology governance (ITG) practices rely on both human and nonhuman actors to support the creation of business value in organisations. The role of nonhuman actors in shaping the ITG practices has been given limited attention within the ITG literature. In proposing a model of ITG, this paper highlights the interplay of human and technological artefacts in shaping the ITG practices. Using a case study approach, this paper explores the relationship and interaction between ITG arrangements and IT infrastructure in an IT centralisation project conducted over a number of years in a university. The analysis from this study highlights how problems in aligning actors’ interests and lack of appropriate strategies lead to a failure in establishing a stable ITG network.

Factors affecting capital program performance audit findings

Complex capital programs require specialized management techniques, in order to address the volatility, cost overruns, significant delays in completion, and failures with which such programs are typically associated. The need is greater than ever for careful oversight, especially for programs that expend public monies.

Audit is commonly a statutory or governance requirement on such programs, but traditional performance audit techniques and standards may be insufficient for certain types of programs and industries, providing a mere illusion of oversight adequacy instead of the assurance that is needed. In order to most appropriately define the performance audit scope, phrase the solicitation for services, select the audit team, and provide support to the auditors during the engagement, public and private sector entity auditees need to understand the factors that impact performance audit results and effectiveness. The question becomes one of how performance audit can be improved, and stakeholders satisfied regarding program achievements, accountability for resource use, transparency in operations, and risk management.

The author considered program complexity, governance, project controls, the history and evolution of the audit function, stakeholder expectations, assurance, and obstacles to audit, and used this information in conjunction with data from a large sample of 775 audit reports from complex construction programs, to derive questions and conclusions about performance audit results and effectiveness, and comparisons to expenditure audit results. The ultimate goal was to define key components in the execution of performance audits, based on theconclusions of the analysis, in order to improve performance audit findings and thus their applicability and usefulness.

While this study focused on program performance audit, it was also related to the field of program management. Although the data population was concentrated in the area of construction programs, conclusions from this research may also be applied to other complex, multifaceted or phased activities such as projects and programs in other industries (manufacturing, information technology), and also pursuits such as major event planning, company launch, mergers, and large program implementations or rollouts.

The research results clearly demonstrated that different types of findings were generated by different audit scopes. The author observed that typical audit findings focused on routine procedural, accounting, and controls errors. On average, contract expenditure audits questioned only 2.65% of expenditures, and performance audits of large complex programs questioned only 0.03% of expenditures. The majority (72.56%) of the performance audits in the sample yielded no findings or questioned costs.

There were significant positive correlations between: the number of expenditures tested and the number of qualitative findings, inclusion of construction experts on the audit team and the percentage of expenditures questioned, inclusion of construction experts on the audit team and the number of qualitative findings, broader audit scope and the percentage of expenditures questioned, and broader audit scope and the number of qualitative findings. Of these, auditor expertise and audit scope were the driving factors.

There were significant negative correlations between the application of agreed-upon procedures and the percentage of expenditures questioned, and the application of agreed upon-procedures and the number of qualitative findings. It was determined that the significant negative correlation between the application of audit standards and the number of qualitative findings was due to other factors, such as the application of agreed-upon procedures and the lack of construction experts on the audit team.

Other findings, resulting from review of the data, were unrelated to the research questions yet of considerable importance to industry. An extremely high percentage (81%) of the “performance audits” instead applied a very limited set of agreed-upon-procedures (AUP) in the engagement, According to the American Institute of Certified Public Accountants (CPAs), AUP engagements could not be classified as audits. Thus, it was inappropriate for the accounting firms to apply AUP engagements in lieu of a performance audit, and it was especially egregious for them to state in their report that the engagements were conducted in accordance with audit standards, as AUP engagements and the specific audit standards were by their very nature mutually exclusive.

Developing a facility for glass façade performance testing

This research aims to investigate whether real spaces can support legitimate measurements on glazing energy and thermal comfort analysis. This paper presents the development of a research facility for doing this. It will test simple to complex glazing and shading systems in a real (occupied) interior office environment. The purpose of this research project is to compare measured results with those being simulated with existing software and to discover discrepancies between simulation and real measured results. What parameters characterize a glazing system, whether simple or complex? Can these parameters be used to predict the energy transfer and comfort in the space? One must begin with simple glazing systems and verify measured with readily known simulated results. It is, at present, very difficult to use geometric based software with thermal based software to predict the performance of complex glazing systems. However, if we can characterize glazing systems with a set of reliable measurements, we can provide the data necessary for predicting performance in a live space. Specifically, the Solar Heat Gain Coefficient (SHGC) is a variable parameter based upon solar incident angle to a glazing system and is intended to be measured in its integral components: solar transmittance and inward-flowing fraction (radiative/convective) heat gain. A new instrumental approach through variable surface coated heat flux meters is being investigated to provide the measurement of interior glazing surface radiative and convective heat gain. The results suggest that this instrumentation may support be a viable method of testing inward-flowing heat gains from the interior glass surface. The test set-up also considers the application of a well-known B&K 1221 Comfort Meter for determining thermal comfort responses in the ‘perimeter zone’ on the interior side of a façade. This work requires further investigation, but is intended to be used in conjunction with solar pyranometers measuring transmittance as well as the heat flux meter and surface temperature instrumentation.

Construction cost performance of structural frames in Australia

This research is concerned with the comparative cost of building structural frames in Australia. The research has been undertaken to evaluate the cost performance of a number of technologies that are typically used in medium-rise commercial buildings of ten storeys. The research methodology is based on pricing a number of standard building frame designs in five Australian cities. The results represent the cost of producing the same building using different building construction designs. By utilising a standard model, project variables like building quality, ground conditions and access were eradicated, thereby facilitating an unbiased comparison of cost performance. The second stage of the research invoiced a focus group of industry experts who were asked to validate the results of the cost study. In addition, participants of the focus group were asked to comment on the preferred construction practice for each of the typical building designs. Results suggest that post-tensioned in situ concrete frames have the best cost performance for most buildings. However, other designs can have good cost performance under some circumstances. Findings suggest that the Australian construction industry has long cultural preference for the use of in situ concrete in structural frames.

The impact of performance skills on students’ attitudes towards the learning experience in higher education

One way to assist in transforming a lecture experience into an occasion that can attract and engage students is via the use of performance techniques. Investigating the impact of certain types of performance skills on students' attitudes towards the learning experience can help better understand the relevance of such techniques in face to face and online learning experiences. This paper outlines a project which: i) surveyed students about their attitudes towards face to face and online recorded lectures, ii) surveyed students about their attitudes towards performance techniques, in particular, spatial awareness, vocalisation, eye contact and passion, iii) interviewed lecturers about the potential benefits of performance techniques to student learning in the lecture theatre, and iv) investigated which factors most affected a teacher's decision to incorporate performance techniques in the lecture theatre. The results suggest that students and lecturers value face to face delivery of content, recognising the benefit of performance techniques in the lecture theatre. Recommendations are made regarding ways to encourage a wider use and evaluation of performance techniques in teaching and learning at the university level.

Corner Inlet and Nooramunga Habitat Mapping Project – Part 2 : High resolution mapping and change detection analysis using 2011 Rapid Eye Satellite Image compared to 2009 ALOS Satellite Image

Building on a habitat mapping project completed in 2011, Deakin University was commissioned by Parks Victoria (PV) to apply the same methodology and ground-truth data to a second, more recent and higher resolution satellite image to create habitat maps for areas within the Corner Inlet and Nooramunga Marine and Coastal Park and Ramsar area. A ground-truth data set using in situ video and still photographs was used to develop and assess predictive models of benthic marine habitat distributions incorporating data from both RapidEye satellite imagery (corrected for atmospheric and water column effects by CSIRO) and LiDAR (Light Detection and Ranging) bathymetry. This report describes the results of the mapping effort as well as the methodology used to produce these habitat maps.

Overall accuracies of habitat classifications were good, with error rates similar to or better than the earlier classification (>73 % and kappa values > 0.58 for both study localities). The RapidEye classification failed to accurately detect Pyura and reef habitat classes at the Corner Inlet locality, possibly due to differences in spectral frequencies. For comparison, these categories were combined into a ‘non-seagrass’ category, similar to the one used at the Nooramunga locality in the original classification. Habitats predicted with highest accuracies differed from the earlier classification and were Posidonia in Corner Inlet (89%), and bare sediment (no-visible seagrass class) in Nooramunga (90%). In the Corner Inlet locality reef and Pyura habitat categories were not distinguishable in the repeated classification and so were combined with bare sediments. The majority of remaining classification errors were due to the misclassification of Zosteraceae as bare sediment and vice versa. Dominant habitats were the same as those from the 2011 classification with some differences in extent. For the Corner Inlet study locality the no-visible seagrass category remained the most extensive (9059 ha), followed by Posidonia (5,513 ha) and Zosteraceae (5,504 ha). In Nooramunga no-visible seagrass (6,294 ha), Zosteraceae (3,122 ha) and wet saltmarsh (1,562 ha) habitat classes were most dominant.

Change detection analyses between the 2009 and 2011 imagery were undertaken as part of this project, following the analyses presented in Monk et al. (2011) and incorporating error estimates from both classifications. These analyses indicated some shifts in classification between Posidonia and Zosteraceae as well as a general reduction in the area of Zosteraceae. Issues with classification of mixed beds were apparent, particularly in the main Posidonia bed at Nooramunga where a mosaic of Zosteraceae and Posidonia was seen that was not evident in the ALOS classification. Results of a reanalysis of the 1998-2009 change detection illustrating effects of binning of mixed beds is also provided as an appendix.

This work has been successful in providing baseline maps at an improved level of detail using a repeatable method meaning that any future changes in intertidal and shallow water marine habitats may be assessed in a consistent way with quantitative error assessments. In wider use, these maps should also allow improved conservation planning, advance fisheries and catchment management, and progress infrastructure planning to limit impacts on the Inlet environment.

Performance evaluation of e-government services using balance scorecard : an empirical study in Jordan

Purpose - the purpose of this paper is to emphasise on a balance between quantitative and qualitative measures, and examine the use of Balanced Scorecard to evaluate and estimate the performance of information and communication technologies (ICT) in delivering valuable e-government services through the internet. Design/methodology/approach - This study tests the hypotheses of e-government effectiveness using Balanced Scorecard technique by incorporating qualitative measures within a quantitative research methodology with data collected by means of a survey questionnaire. The survey sample of 383 stakeholders includes common customers, employees of e-government, and employees from the IT sector. The survey data were analysed to test the hypothesis in measuring e-government effectiveness from Balanced Scorecard's four dimensions: customer perspective, financial perspective, internal business process perspective, and innovation and learning perspective. Findings - The results show that the Balanced Scorecard factors fit very well with monitoring and measuring the performance of e-government in Jordan, and also in evaluating their success in IT project investments. Originality/value - This study attempts to address this gap in the literature and would benefit future studies in applying Balanced Scorecard for performance evaluation of various IT projects that are gaining huge investments from governments and organisations .

Integrated approach of sustainability and climate change adaptation in a metro project

The new Melbourne Metro underground rail project will leave a legacy long into the future, with an estimated design life which will extend beyond 100 years. As such it is extremely important to consider the mitigation of any environmental impacts, providing a sustainable outcome. It is also essential to pre-empt required adaptation of buildings and infrastructure in the future against the impact of changes in the local climate. Designing a metro system in the age of climate change provides the opportunity to go beyond standard specifications and compliance requirements, creating innovative sustainable and climate resilient design outcomes. On the contrary, constructing an underground metro project presents various design challenges fuelled by complex constraints, many uncertainties and risks. This paper will review the methodology used to integrate environmentally sustainable principles and resilient design for climate change adaptation, within the concept development phase of the Melbourne Metro Underground Rail Project.

Factors affecting commitment and satisfaction of project managers in the construction industry

Construction project managers normally need develop their professional knowledge and practical skills in construction technologies and management on the basis of long term work experience. Their organizational commitment and job satisfaction level significantly influence their performance attitudes and job achievements. Keeping construction project managers highly committed to and satisfied with the employed companies is extremely vital to employed construction companies but is really difficulty due to the non-attractive job circumstances. This research investigates the major demographic variables that affect the organizational commitment and job satisfaction of project managers in the construction industry. Based on an empirical study, the statistical results indicate that some demographical variables play a substantial role in construction project managers' organizational commitment and job satisfaction. With this knowledge, construction organizations can draw up operational strategies to retain their project managers.

Engineering a distributed infrastructure for large-scale cost-effective content dissemination over urban vehicular networks

This paper proposes a practical and cost-effective approach to construct a fully distributed roadside communication infrastructure to facilitate the localized content dissemination to vehicles in the urban area. The proposed infrastructure is composed of distributed lightweight low-cost devices called roadside buffers (RSBs), where each RSB has the limited buffer storage and is able to transmit wirelessly the cached contents to fast-moving vehicles. To enable the distributed RSBs working toward the global optimal performance (e.g., minimal average file download delays), we propose a fully distributed algorithm to determine optimally the content replication strategy at RSBs. Specifically, we first develop a generic analytical model to evaluate the download delay of files, given the probability density of file distribution at RSBs. Then, we formulate the RSB content replication process as an optimization problem and devise a fully distributed content replication scheme accordingly to enable vehicles to recommend intelligently the desirable content files to RSBs. The proposed infrastructure is designed to optimize the global network utility, which accounts for the integrated download experience of users and the download demands of files. Using extensive simulations, we validate the effectiveness of the proposed infrastructure and show that the proposed distributed protocol can approach to the optimal performance and can significantly outperform the traditional heuristics.
