Liquid Crystalline Graphene Oxide/Pedot: Pss Self-Assembled 3d Architecture For Binder-Free Supercapacitor Electrodes, Md. Monirul Islam, Alfred T. Chidembo, Seyed Hamed Aboutalebi, Dean Cardillo, Hua-Kun Liu, Konstantin K. Konstantinov, S X. Dou Jan 2014

Liquid Crystalline Graphene Oxide/Pedot: Pss Self-Assembled 3d Architecture For Binder-Free Supercapacitor Electrodes, Md. Monirul Islam, Alfred T. Chidembo, Seyed Hamed Aboutalebi, Dean Cardillo, Hua-Kun Liu, Konstantin K. Konstantinov, S X. Dou

Australian Institute for Innovative Materials - Papers

Binder-free self-assembled 3D architecture electrodes have been fabricated by a novel convenient method. Liquid crystalline graphene oxide was used as precursor to interact with poly(3,4-ethylene-dioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in dispersion in order to form a conductive polymer entrapped, self-assembled layer-by-layer structure. This advanced network containing PEDOT:PSS enabled us to ascribe the superior electrochemical properties of particular graphene sheets. This layer-by-layer self-assembled 3D architecture of best performing composite (reduced graphene oxide-PEDOT:PSS 25) showed excellent electrochemical performance of 434 F g−1 through chemical treatment. To highlight these advances, we further explored the practicality of the as-prepared electrode by varying the composite material content. …


An Architecture Framework Modification Supporting The Acquisition Stakeholders, Farid Shirvani, Mahmoud Efatmaneshnik, Allan P. Campbell Jan 2014

An Architecture Framework Modification Supporting The Acquisition Stakeholders, Farid Shirvani, Mahmoud Efatmaneshnik, Allan P. Campbell

Faculty of Engineering and Information Sciences - Papers: Part A

Architectural modeling is gaining support for urban system development to help governments, local agencies and large enterprises acquire, maintain and develop complex infrastructure. This paper proposes a modification to TRAK (The Rail Architecture frameworK) to make it more suitable for acquisition of the general class of urban infrastructure systems. In this paper four of the main system stakeholders, namely acquirer, developer, investor and regulator are chosen and their concerns are identified. In order to identify the gaps, the procurement viewpoints of TRAK are investigated and analyzed to show their inefficiencies in expressing acquisition scenarios and addressing the concerns of those …


Agile Enterprise Architecture: A Case Of A Cloud Technology-Enabled Government Enterprise Transformation, Asif Qumer Gill, Steven Smith, Ghassan Beydoun, Vijayan Sugumaran Jan 2014

Agile Enterprise Architecture: A Case Of A Cloud Technology-Enabled Government Enterprise Transformation, Asif Qumer Gill, Steven Smith, Ghassan Beydoun, Vijayan Sugumaran

Faculty of Engineering and Information Sciences - Papers: Part A

Australian government enterprises have shown a significant interest in the cloud technology-enabled enterprise transformation. Australian government suggests the whole-of-a-government strategy to cloud adoption. The challenge is how best to realise this cloud adoption strategy for the cloud technology-enabled enterprise transformation? The cloud adoption strategy realisation requires concrete guidelines and a comprehensive practical framework. This paper proposes the use of an agile enterprise architecture framework to developing and implementing the adaptive cloud technology-enabled enterprise architecture in the Australian government context. The results of this paper indicate that a holistic strategic agile enterprise architecture approach seems appropriate to support the strategic whole-of-a-government …


Feasibility Study On The Implementation Of Ieee 802.11 On Cloud-Based Radio Over Fibre Architecture, Sen Zhang, Daniel Franklin Jan 2014

Feasibility Study On The Implementation Of Ieee 802.11 On Cloud-Based Radio Over Fibre Architecture, Sen Zhang, Daniel Franklin

Faculty of Engineering and Information Sciences - Papers: Part A

This paper investigates the throughput performance of the IEEE 802.11 MAC when the physical layer is implemented remotely on a cloud-based SDR platform. An analytical model which considers a non-zero late ACK arrival probability is proposed to analyse throughput performance. Both conventional DCF and the Block ACK enhancement from current IEEE 802.11 standards are analysed using the proposed model. Results show that the network delay variance significantly degrades the performance of conventional DCF while enabling Block ACK significantly reduces this degradation.


A Distributed Consensus Algorithm For Decision Making In Service-Oriented Internet Of Things, Shancang Li, George Oikonomou, Theo Tryfonas, Thomas M. Chen, Li Da Xu Jan 2014

A Distributed Consensus Algorithm For Decision Making In Service-Oriented Internet Of Things, Shancang Li, George Oikonomou, Theo Tryfonas, Thomas M. Chen, Li Da Xu

Information Technology & Decision Sciences Faculty Publications

In a service-oriented Internet of things (IoT) deployment, it is difficult to make consensus decisions for services at different IoT edge nodes where available information might be insufficient or overloaded. Existing statistical methods attempt to resolve the inconsistency, which requires adequate information to make decisions. Distributed consensus decision making (CDM) methods can provide an efficient and reliable means of synthesizing information by using a wider range of information than existing statistical methods. In this paper, we first discuss service composition for the IoT by minimizing the multi-parameter dependent matching value. Subsequently, a cluster-based distributed algorithm is proposed, whereby consensuses are …


Ghosts Of The Horseshoe, Heidi Rae Cooley, Richard Walker, Duncan Buell Jan 2014

Ghosts Of The Horseshoe, Heidi Rae Cooley, Richard Walker, Duncan Buell

Digital Projects

Ghosts of the Horseshoe (Ghosts) is a mobile interactive application that endeavors to bring into view--literally, on mobile micro screens (iPads and iPhones at present)--the largely unknown history of slavery at South Carolina College. It deploys game mechanics (i.e., ludic methods), as well as Augmented Reality (AR) and GPS functionality to generate awareness of and questioning about what otherwise seems ordinary: a grassy space at the center of a university campus. It organizes content into distinct but overlapping themes: (1) architectural ghosts (e.g., razed outbuildings); (2) human ghosts (e.g., un/named enslaved persons); and (3) the historic Wall delimiting the Horseshoe …
