Lightweight Data Compression In Wireless Sensor Networks Using Huffman Coding, Henry P. Medeiros, Marcos C. Maciel, Richard D. Souza, Marcelo E. Pellenz Jan 2014

Lightweight Data Compression In Wireless Sensor Networks Using Huffman Coding, Henry P. Medeiros, Marcos C. Maciel, Richard D. Souza, Marcelo E. Pellenz

Electrical and Computer Engineering Faculty Research and Publications

This paper presents a lightweight data compression method for wireless sensor networks monitoring environmental parameters with low resolution sensors. Instead of attempting to devise novel ad hoc algorithms, we show that, given general knowledge of the parameters that must be monitored, it is possible to efficiently employ conventional Huffman coding to represent the same parameter when measured at different locations and time periods. When the data collected by the sensor nodes consists of integer measurements, the Huffman dictionary computed using statistics inferred from public datasets often approaches the entropy of the data. Results using temperature and relative humidity measurements show …

Antimicrobial Properties Of Vertically Aligned Nano-Tubular Copper, Kafil Razeeb, Joanna Podporska-Carroll, Mamun Jamal, Maksudul Hassan, Michael Nolan, Declan Mccormack, Brid Quilty, Simon Newcombe, Suresh Pillai

Articles

In this work, the antimicrobial properties of vertically aligned nano-tubular Cu arrays (NT-Cu) fabricated via a template-based electrodeposition approach were investigated. The NT-Cu display good bactericidal activity against S.aureus and bacteriostatic properties against E.coli, S.sonnei, S.enterica and C.albicans. In contrast, Cu-foil electrodeposited from the same solution shows low biological activity against the same microorganisms. The antimicrobial activity of NT-Cu depends on both the type of microorganism and exposure time. After 6 hours of exposure, over 99.99% (log red = 4.43) of S.aureus population was inactivated, whereas, for E.coli, S.sonnei, S.enterica and C.albicans it was 97.8, 94.2, 89.9, and 90.3%, respectively.

Children’S Rights Online: Challenges, Dilemmas And Emerging Directions, Sonia Livingstone, Brian O'Neill Jan 2014

Children’S Rights Online: Challenges, Dilemmas And Emerging Directions, Sonia Livingstone, Brian O'Neill

Articles

Although it is widely held that a more inclusive and trusted internet can support a competitive knowledge economy, a digitally skilled labour force, civic participation and a pluralistic media sector, governments and regulators have tended to avoid intervening directly to achieve these aims, believing that industry is best positioned to respond to the fast pace of change in information and communication technologies (ICT).This reflects a wider policy shift away from top-down government measures towards flexible, dispersed and indirect forms of governance, encompassing industry self-regulation as well as elements of cooperation or co-regulation with relevant state agencies.

Towards The Grounding Of Abstract Categories In Cognitive Robots, Francesca Stramandinoli Jan 2014

Towards The Grounding Of Abstract Categories In Cognitive Robots, Francesca Stramandinoli

School of Engineering, Computing and Mathematics Theses

The grounding of language in humanoid robots is a fundamental problem, especially in social scenarios which involve the interaction of robots with human beings. Indeed, natural language represents the most natural interface for humans to interact and exchange information about concrete entities like KNIFE, HAMMER and abstract concepts such as MAKE, USE. This research domain is very important not only for the advances that it can produce in the design of human-robot communication systems, but also for the implication that it can have on cognitive science. Abstract words are used in daily conversations among people to describe events and situations …

Non-Intrusive Continuous User Authentication For Mobile Devices, Sevasti Karatzouni Jan 2014

Non-Intrusive Continuous User Authentication For Mobile Devices, Sevasti Karatzouni

School of Engineering, Computing and Mathematics Theses

The modern mobile device has become an everyday tool for users and business. Technological advancements in the device itself and the networks that connect them have enabled a range of services and data access which have introduced a subsequent increased security risk. Given the latter, the security requirements need to be re-evaluated and authentication is a key countermeasure in this regard. However, it has traditionally been poorly served and would benefit from research to better understand how authentication can be provided to establish sufficient trust. This thesis investigates the security requirements of mobile devices through literature as well as acquiring …

Non-Linear Model Predictive Control Strategies For Process Plants Using Soft Computing Approaches, Kayode Olayemi Owa Jan 2014

Non-Linear Model Predictive Control Strategies For Process Plants Using Soft Computing Approaches, Kayode Olayemi Owa

School of Engineering, Computing and Mathematics Theses

The developments of advanced non-linear control strategies have attracted a considerable research interests over the past decades especially in process control. Rather than an absolute reliance on mathematical models of process plants which often brings discrepancies especially owing to design errors and equipment degradation, non-linear models are however required because they provide improved prediction capabilities but they are very difficult to derive. In addition, the derivation of the global optimal solution gets more difficult especially when multivariable and non-linear systems are involved. Hence, this research investigates soft computing techniques for the implementation of a novel real time constrained non-linear model …

A Review Of Virtualisation And Cloud Computing In Higher Education, Eileen O'Donnell Jan 2014

A Review Of Virtualisation And Cloud Computing In Higher Education, Eileen O'Donnell

Books/Book Chapters

Virtualisation in the classroom provides students with the impression that they are interacting with applications, services, and files which are stored locally, when in fact the applications, services, and files may be stored on a server off site, or at an alternative location on site. “Virtualization is a technology that permits the abstraction of the software from one computer and its easy deployment in another one, which may house additional virtualized machines” (Martín, Marrero, Urbano, Barra, & Moreiro, 2011, p. 349). Server virtualisation is when an Information Technology manager or computer administrator partitions a server to create several instances of …

Service Composition Based On Sip Peer-To-Peer Networks, Armin Lehmann

School of Engineering, Computing and Mathematics Theses

Today the telecommunication market is faced with the situation that customers are requesting for new telecommunication services, especially value added services. The concept of Next Generation Networks (NGN) seems to be a solution for this, so this concept finds its way into the telecommunication area. These customer expectations have emerged in the context of NGN and the associated migration of the telecommunication networks from traditional circuit-switched towards packet-switched networks. One fundamental aspect of the NGN concept is to outsource the intelligence of services from the switching plane onto separated Service Delivery Platforms using SIP (Session Initiation Protocol) to provide the …

Personalising Information Security Education, Shuhaili Talib Jan 2014

Personalising Information Security Education, Shuhaili Talib

School of Engineering, Computing and Mathematics Theses

Whilst technological solutions go a long way in providing protection for users online, it has been long understood that the individual also plays a pivotal role. Even with the best of protection, an ill-informed person can effectively remove any protection the control might provide. Information security awareness is therefore imperative to ensure a population is well educated with respect to the threats that exist to one’s electronic information, and how to better protect oneself. Current information security awareness strategies are arguably lacking in their ability to provide a robust and personalised approach to educating users, opting for a blanket, one-size-fits-all …
