Evolutionary Learner Profile Optimization Using Rare And Negative Association Rules For Micro Open Learning, Geng Sun, Jiayin Lin, Jun Shen, Tingru Cui, Dongming Xu, Huaming Chen Jan 2020

Evolutionary Learner Profile Optimization Using Rare And Negative Association Rules For Micro Open Learning, Geng Sun, Jiayin Lin, Jun Shen, Tingru Cui, Dongming Xu, Huaming Chen

Faculty of Engineering and Information Sciences - Papers: Part B

The actual data availability, readiness and publicity has slowed down the research of making use of computational intelligence to improve the knowledge delivery in an emerging learning mode, namely adaptive micro open learning, which naturally has high demand in quality and quantity of data to be fed. In this study, we contribute a novel approach to tackle the current scarcity of both data and rules in micro open learning, by adopting evolutionary algorithm to produce association rules with both rare and negative associations taken into account. These rules further drive the generation and optimization of learner profiles through refinement and …


Myth Or Fact: Is Open Source Software More Secure Than Closed Source Software?, Daniel Saffioti, Gene Awyzio, Robert B. K. Brown Apr 2019

Myth Or Fact: Is Open Source Software More Secure Than Closed Source Software?, Daniel Saffioti, Gene Awyzio, Robert B. K. Brown

Associate Professor Daniel F. Saffioti

This paper examines one aspect of quality that organizations look for when selecting software, namely security. Studies over time have indicated that security; scalability, interoperability and flexibility are important however the major issue has always been support. This has led to the sometimes inflexible concept of Standard Operating Environments (SOEs) within organisations. Whilst SOEs provide many benefits to an organisation they can leave them vulnerable to several large security risks. CERT statistics show that security incidents have increased six fold since 2000 [1]. This paper will examine trends in both open and closed software development for a number of platforms …

Micro Learning through open educational resources (OERs) is becoming increasingly popular. However, adaptive micro learning support remains inadequate by current OER platforms. To address this, our smart system, Micro Learning as a Service (MLaaS), aims to deliver personalized OER with micro learning to satisfy their real-time needs.

Organizing Online Computation For Adaptive Micro Open Education Resource Recommendation, Geng Sun, Tingru Cui, Ghassan Beydoun, Shiping Chen, Dongming Xu, Jun Shen Jan 2017

Organizing Online Computation For Adaptive Micro Open Education Resource Recommendation, Geng Sun, Tingru Cui, Ghassan Beydoun, Shiping Chen, Dongming Xu, Jun Shen

Our previous work, Micro Learning as a Service (MLaaS), aimed to deliver adaptive micro open education resources (OERs). However, relying solely on the offline computation, the recommendation lacks rationality and timeliness. It is also difficult to make the first recommendation to a new learner. In this paper we introduce the organization of the online computation of the MLaaS. It targets at solving the cold start problem due to the shortage of learner information and real-time updates of the learner-micro OER profile


Information Technology And Open Innovation: A Strategic Alignment Perspective, Tingru Cui, Hua Ye, Hock Hai Teo, Jizhen Li Jan 2015

Information Technology And Open Innovation: A Strategic Alignment Perspective, Tingru Cui, Hua Ye, Hock Hai Teo, Jizhen Li

Faculty of Engineering and Information Sciences - Papers: Part A

Advances in information technology (IT) have enabled firms to increasingly rely on open innovation. Although researchers and practitioners are interested in this phenomenon, there is a lack of theoretically driven research on how IT impacts organizational open innovation performance. Drawing on the strategic IT alignment perspective and related literature, we proposed a model to explain the performance of organizational open innovation; i.e., the alignment between IT strategies and the openness of open innovation strategies results in different outcomes for open innovation. Through the analysis of data from 225 firms in China, we found that the alignment between IT flexibility and …


Roles Of Social Media In Open Data Environments: A Case Study Of The 2014 Indonesian Presidential Election Voting Results, Uuf Brajawidagda, Akemi T. Chatfield Jan 2014

Roles Of Social Media In Open Data Environments: A Case Study Of The 2014 Indonesian Presidential Election Voting Results, Uuf Brajawidagda, Akemi T. Chatfield

Open data initiatives are critical to open government policies which promote transparency, citizen engagement and collaboration. However, they face challenges in realizing their potential benefits through citizens' active engagement. Despite the sharp rise of social media use by governments or quasi-governmental organizations to engage citizens in transforming public service quality and offers, very little has been written on enabling roles of social media in influencing the outcome of open data initiatives. This research examines the potential enabling roles of social media in motivating and having citizens' engagement easier in open data environments. Specifically, we present social media use in supporting …


Discussion Of "Depth-Averaged Shear Stress And Velocity In Open-Channel Flows" By Shu-Qing Yang, M Sterling, Xiannan Tang Jan 2012

Discussion Of "Depth-Averaged Shear Stress And Velocity In Open-Channel Flows" By Shu-Qing Yang, M Sterling, Xiannan Tang

Faculty of Engineering and Information Sciences - Papers: Part A

The discussers thank the author for writing an informative and thought-provoking paper. Predicting the lateral distribution of boundary shear stress in open-channel flows is an intractable issue, and any theoretical work in this area is to be welcomed. The purpose of this discussion is twofold: first, to compare the analysis developed by the author to experimental data; and second, to seek clarification on several areas of potential confusion, which may be due to typographical errors.

Estimation Of Diffusion Coefficients, Lateral Shear Stress, And Velocity In Open Channels With Complex Geometry, Shu-Qing Yang, Jian-Xing Yu, Yuan-Zhan Wang Jan 2004

Estimation Of Diffusion Coefficients, Lateral Shear Stress, And Velocity In Open Channels With Complex Geometry, Shu-Qing Yang, Jian-Xing Yu, Yuan-Zhan Wang

Faculty of Engineering and Information Sciences - Papers: Part A

The lateral distributions of depth-averaged apparent shear stress, depth mean velocity, and diffusion coefficients are essential in certain quantitative analysis for sediment transport and environmental studies. An analytical method for the computation of these parameters is presented. A mathematical relationship between these parameters, based on the concept of surplus energy transport through a minimum relative distance developed by Yang and Lim [1997], is established, the depth-averaged apparent shear stress is determined from the boundary shear stress, depth mean velocity is obtained by considering the influence of nonuniform shear velocity and the free surface in 3-D channels, and the diffusion coefficients …
