A framework for cloud-based healthcare services to monitor noncommunicable diseases patient

Monitoring patients who have noncommunicable diseases is a big challenge. These illnesses require a continuous monitoring that leads to high cost for patients' healthcare. Several solutions proposed reducing the impact of these diseases in terms of economic with respect to quality of services. One of the best solutions is mobile healthcare, where patients do not need to be hospitalized under supervision of caregivers. This paper presents a new hybrid framework based on mobile multimedia cloud that is scalable and efficient and provides cost-effective monitoring solution for noncommunicable disease patient. In order to validate the effectiveness of the framework, we also propose a novel evaluation model based on Analytical Hierarchy Process (AHP), which incorporates some criteria from multiple decision makers in the context of healthcare monitoring applications. Using the proposed evaluation model, we analyzed three possible frameworks (proposed hybrid framework, mobile, and multimedia frameworks) in terms of their applicability in the real healthcare environment.

Security and privacy concerns for Australian SMEs cloud adoption: empirical study of metropolitan vs regional SMEs

New national infrastructure initiatives such as the National Broadband Network (NBN) allow small and medium-sized enterprises (SMEs) in Australia to have greater access to cost effective Cloud computing. However, the ability of Cloud computing to store data remotely and share services in a dynamic environment brings with it security and privacy concerns. Evaluating these concerns is critical to address the Cloud computing underutilisation issue and leverage the benefits of costly NBN investment. This paper examines the influence of privacy and security factors on Cloud adoption by Australian SMEs in metropolitan and regional area. Data were collected from 150 Australian SMEs (specifically, 79 metropolitan SMEs and 71 regional SMEs) and structural equation modelling was used for the analysis. The findings reveal that privacy and security factors do not significantly influence the decision-making of Australian SMEs in the adoption of Cloud computing. Moreover, the results indicate that Cloud computing adoption is not influenced by the geographical location (i.e., metropolitan or regional location) of the SMEs. The findings extend the current understanding of Cloud computing adoption by Australian SMEs. The results will be useful to SMEs, Cloud service providers and policy makers devising Cloud security and privacy policies.

Congestion control mechanism for sensor-cloud Infrastructure

 This thesis has developed a sensor-Cloud system that integrates WBANs with Cloud computing to enable real-time sensor data collection, storage, processing, sharing and management. As the main contribution of this study, a congestion detection and control protocol is proposed to ensure acceptable data flows are maintained during the network lifetime.

Integrating internet-of-things with the power of cloud computing and the intelligence of big Data analytics- a three layered approach

This paper is written through the vision on integrating Internet-of-Things (IoT) with the power of Cloud Computing and the intelligence of Big Data analytics. But integration of all these three cutting edge technologies is complex to understand. In this research we first provide a security centric view of three layered approach for understanding the technology, gaps and security issues. Then with a series of lab experiments on different hardware, we have collected performance data from all these three layers, combined these data together and finally applied modern machine learning algorithms to distinguish 18 different activities and cyber-attacks. From our experiments we find classification algorithm RandomForest can identify 93.9% attacks and activities in this complex environment. From the existing literature, no one has ever attempted similar experiment for cyber-attack detection for IoT neither with performance data nor with a three layered approach.

PASSport to the cloud – results of a Peer-Assisted Study Sessions (PASS) online pilot program

Deakin University’s online study environment continues to grow with over 12,000 students now studying in the Cloud. It is important to provide these students not only academic support, but also a sense of inclusion and community. This will improve their social engagement and from there, they will more likely succeed. In 2015, the Division of Student Life ran an online pilot based on their successful Peer -Assisted Study Sessions program. Results from the pilot were positive. Students reported greater connection with the subject and with their fellow students. The program will be expanded in 2016 based on this pilot.

Combating cyber attacks in cloud computing using machine learning techniques.

An extensive investigative survey on Cloud Computing with the main focus on gaps that is slowing down Cloud adoption as well as reviewing the threat remediation challenges. Some experimentally supported thoughts on novel approaches to address some of the widely discussed cyber-attack types using machine learning techniques. The thoughts have been constructed in such a way so that Cloud customers can detect the cyber-attacks in their VM without much help from Cloud service provider

Assessing students’ experiences in a virtual learning environment

CONTEXTTechnology has played an important role in the provision of educational equity for learners inAustralian communities. Engaging off-campus students through technology resources is vital for avirtual learning environment in engineering education. To ensure a positive experience for thestudents in off-campus (virtual) learning, the use of modern technology is crucial for collaborative andactive learning.PURPOSEDesign based education is a combination of project based and problem based approaches. Throughsmall or big projects, students work in teams with combinations of off-campus and on-campusstudents. Integration of technology resources takes place within these groups through collaborativelearning and active learning. Even though the facilities and technology support are provided for offcampusstudents, there is always a gap in fulfilling the off-campus students’ learning expectations in avirtual learning environment. Technology plays an important role in providing student engagement insolving design problems, which is a need for the distance learner community in future. The purpose ofthis study is to evaluate students’ experiences on the use of technology in learning and teaching,which is delivered in off-campus mode.APPROACHThe cohorts of students involved in this online survey are from first year undergraduate engineering inTrimester 2, 2016. The online survey analysis of students’ perceptions will help teaching staff to betterunderstand and assess off-campus students’ experiences, challenges and barriers in a virtual learningenvironment.RESULTSThe distance learners’ experiences are analysed from an online survey. This online survey analysesthe students’ experiences on use of technology and how it supports and enhances students learning indistance mode. It also analyses the student learning experiences on project/design-based learningapproach in engineering. In this particular unit (Electrical Systems), students work in teams of 2-3 onlab work and other assignments. The analysed results also discuss the students’ perceptions onteamwork, communication, interaction and assessment.CONCLUSIONSThe aim of the engineering curriculum is to provide learning and teaching support equally for both oncampusand off-campus students. From the analysed survey results, this study reveals that the use oftechnology plays a vital role in students learning from availability and accessibility of materials toassessment methods, lab tutorials, and online seminars. In a project/design based learningcurriculum, the distance learners have an equal opportunity to enhance the learning skills as the oncampusstudents experience in a study environment.
