A Simple Proof Of Euler's Continued Fraction Of E^{1/M}, Joseph Tonien

Faculty of Engineering and Information Sciences - Papers: Part A

A continued fraction is an expression of the form

f₀+ g₀

f₁+g₁

f₂+g₂

and we will denote it by the notation [f₀, (g₀, f₁), (g₁, f₂), (g₂, f₃), … ]. If the numerators g_i are all equal to 1 then we will use a shorter notation [f₀, f₁, f₂, f₃, … ]. A simple continued fraction is a continued fraction with all the …

Tuning Performance Of E-Business Applications Through Automatic Transformation Of Persistent Database Structures, Janusz R. Getta

Faculty of Engineering and Information Sciences - Papers: Part A

Performance of e-business applications strongly depends on internal implementations of persistent database structures and on effective algorithms processing these structures. Commercial database systems, which are the basis of e-business applications typically implement logical database structures with one-size-fits-all persistent storage structure. This work investigates a new class of database systems where a conceptual and logical view of a database can be implemented in many different ways depending on the performance requirements of database applications. We consider the improvements to performance of e-business applications through automatic changes of the persistent database structures in the ways indicated by the performance statistics obtained from …

A Personalized Hybrid Recommendation System Oriented To E-Commerce Mass Data In The Cloud, Fang Dong, Junzhou Luo, Xia Zhu, Yuxiang Wang, Jun Shen

Faculty of Engineering and Information Sciences - Papers: Part A

Personalized recommendation technology in Ecommerce is widespread to solve the problem of product information overload. However, with the further growth of the number of E-commerce users and products, the original recommendation algorithms and systems will face several new challenges: (1) to model user’s interests more accurately; (2) to provide more diverse recommendation modes; and (3) to support large-scale expansion. To address these challenges, from the actual demands of E-commerce applications (as Made-in-China website), a personalized hybrid recommendation system, which can support massive data set, is designed and implemented in this paper by using Cloud technology. Hereinto, the recommendation algorithms are …

Controllable Ring Signatures And Its Application To E-Prosecution, Wei Gao, Guilin Wang, Xueli Wang, Dongqing Xie

Faculty of Engineering and Information Sciences - Papers: Part A

This paper introduces a new concept called controllable ring signature which is ring signature with additional properties as follow. (1) Anonymous identifica-tion: by an anonymous identification protocol, the real signer can anonymously prove his authorship of the ring signature to the verifier. And this proof is non-transferable. (2) Linkable signature: the real signer can generate an anonymous signature such that every one can verify whether both this anonymous signature and the ring signature are generated by the same anonymous signer. (3) Convertibility: the real signer can convert a ring signature into an ordinary signature by revealing the secret information about …

Service Quality, Citizen Satisfaction, And Loyalty With Self-Service Delivery Options To Transforming E-Government Services, Akemi Chatfield, Jazem Alanazi

Faculty of Engineering and Information Sciences - Papers: Part A

With the growing recognition of the citizen's role in service demand and self-service delivery, there is an increased impetus on building citizen satisfaction and loyalty with government's e-services. With the global trend in transforming government services through e-government, research on citizen interactions with web-based selfservice delivery options has been recently emerging in IS and e-government literatures. This study aims to contribute to post-adoption research by developing a model of citizen loyalty with government online self-service delivery options. We empirically test the proposed model through an analysis of 402 survey data collected from Saudi citizens/users of e-government transactional services. Multiple regression …

Chen's Conjecture And E-Superbiharmonic Submanifolds Of Riemannian Manifolds, Glen Wheeler

Faculty of Engineering and Information Sciences - Papers: Part A

B.-Y. Chen famously conjectured that every submanifold of Eu- clidean space with harmonic mean curvature vector is minimal. In this note we prove a much more general statement for a large class of submanifolds sat- isfying a growth condition at innity. We discuss in particular two popular competing natural interpretations of the conjecture when the Euclidean back- ground space is replaced by an arbitrary Riemannian manifold. Introducing the notion of "-superbiharmonic submanifolds, which contains each of the pre- vious notions as special cases, we prove that "-superbiharmonic submanifolds of a complete Riemannian manifold which satisfy a growth condition at innity …

E-Learning Barriers In The United Arab Emirates: Preliminary Results From An Empirical Investigation, Lejla Vrazalic, Robert C. Macgregor, D Behl, Jean Fitzgerald

Faculty of Engineering and Information Sciences - Papers: Part A

E-learning is relatively new to the United Arab Emirates. Most tertiary institutions have allocated ICT resources to provide alternatives to the previously used teacher-centred "chalk and talk" approach to learning and teaching. However we have not yet developed a comprehensive understanding of the application of e-learning methods and resources in the tertiary education sector in the UAE. This paper describes a collaborative research project which empirically investigated the perceived barriers to e-learning for students studying at tertiary institutions in the UAE using an online questionnaire. The paper analyses the associations between e-learning barriers and students' age and gender. The ease …

Doing It Tough: Factors Impacting On Local E-Government Mmaturity, Peter Shackleton, Linda Dawson

Faculty of Engineering and Information Sciences - Papers: Part A

As growing numbers of citizens seek to use the Internet to do business, governments across the world have moved into the area of electronic service delivery. For the last decade significant advancements have been made in the area of e-Government. Today, e-Government is often assumed to be wellestablished. However, ongoing support is often missing, particularly at the local government level. The multi-level nature of government often means that citizens are frustrated when accessing services that span many levels of bureaucracy. This paper describes an empirical study which explores the factors influencing local egovernment maturity and identifies the barriers, enablers, priorities …

The Effect Of Small Business Clusters In Prioritising Barriers To E-Commerce Adoption In Regional Smes, Robert Macgregor, Lejla Vrazalic

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents a study of Swedish regional small businesses which investigated the barriers to E-commerce adoption (amongst other things). The aim of the paper is twofold: to examine the correlation between barriers to E-commerce adoption in order to identify underlying factors: and to determine whether these differ between SMEs that are members of a small business cluster and SMEs that are not. The paper begins by examining the nature of SMEs and identifying features that are unique to SMEs. A discussion of barriers to E-commerce adoption based on previous research is then presented and the barriers are mapped to …

Equity Issues In E-Education, Penelope Mcfarlane, Anne Fuller

Faculty of Engineering and Information Sciences - Papers: Part A

The potential of the World Wide Web as a medium for course delivery was early recognized, and universities were quick to take advantage of its possibilities for reaching a wider and more diverse student population. As the amount of course content being offered online increases, both to internal and external students, universities are increasingly exposed to the possibility that students may claim they are disadvantaged by either the mode of delivery or, in the case of overseas students, the content itself. In this paper we review the explosion in internet-based delivery of courses and discuss the areas where we believe …

Molecular Epidemiology Of Escherichia Coli 0157:H7 Strains By Bacteriophage A Restriction Fragment Length Polymorphism Analysis: Application To A Multistate Foodborne Outbreak And A Day-Care Center Cluster, Mansour Samadpour, Linda M. Grimm, B Desai, Dalia Alfi, Jerry E. Ongerth, Phillip I. Tarr

Faculty of Engineering and Information Sciences - Papers: Part A

Genomic DNAs prepared from 168 isolates of Escherichia coli 0157:H7 were analyzed for restriction fragment length polymorphisms on Southern blots probed with bacteriophage A DNA. The isolates analyzed included strains from a recent large multistate outbreak of E. coli 0157:H7 infection associated with consumption of poorly cooked beef in restaurants, a day-care center cluster, and temporally and geographically unrelated isolates. E. coli 0157:H7 isolates recovered from the incriminated meat and from 61 (96.8%) of 63 patients from Washington and Nevada possessed identical A restriction fragment length patterns. The A restriction fragment length polymorphisms observed in 11 (91.7%) of 12 day-care …
