1.Problem-based learning into the future: Imagining an agile PBL ecology for learning

Author:Kek,Megan Yih Chyn A.;Huijser,Henk

Source:Problem-Based Learning into the Future: Imagining an Agile PBL Ecology for Learning,2016,Vol.

Abstract:© Springer Science+Business Media Singapore 2017. In this book we respond to a higher education environment that is on the verge of profound changes by imagining an evolving and agile problem-based learning ecology for learning. The goal of doing so is to humanise university education by pursuing innovative approaches to student learning, teaching, curricula, assessment, and professional learning, and to employ interdisciplinary methods that go far beyond institutional walls and include student development and support, curriculum sustainability, research and the scholarship of teaching and learning, as well as administration and leadership. An agile problem-based learning (PBL) ecology for learning deliberately blurs the boundaries between disciplines, between students and teachers, between students and employers, between employers and teachers, between academics and professional staff, between formal and informal learning, and between teaching and research. It is based on the recognition that all of these elements are interconnected and constantly evolving, rather than being discrete and static. Throughout this book, our central argument is that there is no single person who is responsible for educating students. Rather, it is everyone’s responsibility - teachers, students, employers, administrators, and wider social networks, inside and outside of the university. Agile PBL is about making connections, rather than erecting barriers. In summary, this book is not about maintaining comfort zones, but rather about becoming comfortable with discomfort. The actual implementation is beyond the scope of this book and we envisage that changing perceptions towards this vision will itself be a mammoth task. However, we believe that the alternative of leaving things as they are would ultimately prove untenable, and more distressingly, would leave a generation of students afraid to think, feel, and act for themselves, let alone being able to face the challenges of the 21st century.

2.Usable Authentication Mechanisms for Mobile Devices: An Exploration of 3D Graphical Passwords

Author:Yu, Z;Olade, I;Liang, HN;Fleming, C


Abstract:Current authentication systems in mobile devices such as smart phones have many shortcomings. Users tend to use simple textual passwords such as PINs, which are easily cracked by intruders. Meanwhile, graphical passwords suffer from shoulder surfing attack In this paper, a new authentication system using 3D graphical passwords, will be proposed and tested to offer more security for mobile devices. This authentication system allows users to interact with the 3D objects in a 3D virtual environment and these actions are tracked in the virtual environment and used to create unique passwords. Based on the previous studies of the 3D password scheme, this paper developed a simple testing program that enables users to create their own 3D password easily. At the end of the paper, some improvements of the program and this authentication system are discussed.

4.Impact of Parasitic Elements on RF Performance of Nanometre-Scale MOSFET Structures

Author:Lam, S


Abstract:A recently reported nanometre-scaled MOSFET structure with regrown source and drain is examined. The parasitic circuit elements are identified and quantitatively determined to estimate their impact on the transistor's RF performance. Due to the relatively large lateral parasitic capacitances from the gate electrode to the regrown source and drain regions, the current gain cut-off frequency f(T) of such a transistor is optimistically estimated to be 184 GHz which is not impressive for nanoelectronic devices with an effective gate length of 30 nm. However, with the significantly reduced parasitic series resistances due to the regrown source and drain structures together with the use of the metal gate, the maximum frequency of oscillation f(max) can attain to 820 GHz. This brings about an implication that device structure optimization to reduce the parasitic resistances has a dominant beneficial effect on the RF performance over the negative impact caused by the increased parasitic capacitances.

5.Institutional perspective on emerging industry development: Foreign experiences and policy implications for China


Source:Journal of Science and Technology Policy in China,2011,Vol.2

Abstract:Purpose: The purpose of this paper is to elucidate the dynamic interactions and co-evolution of institutions with the technology and organization fields in emerging industry development. Insights and inspirations from comparison of the triangle relationship among government, market and local community in different institutional contexts could contribute to possible institutional innovation in the context of large-scale institutional transition. In this way, this paper is expected to offer insights to the development of emerging industries in China. Design/methodology/approach: The paper reviews the focal literature focusing on institutional change and the co-evolution of institution, industry and technology. A multi-level conceptual framework is put forward to explain the mechanism for the co-evolution of technology, organization and institution. A multi-case comparison method was applied to compare and disclose the process of co-evolution of institutions, and the technology and organizational fields, as well as varied paths of industry development in different institutional contexts. Findings: Emerging industry development in China is still presenting the character of path dependence to a great extent under traditional institutional arrangement, while the power and possible contribution from broader actors in the local community have been ignored. Driving force for a more innovative institutional transition towards emerging industry development should consider decentralized institutional arrangement and actions at local community instead of "command and control" from central planning. Practical implications: First, the comparison of wind energy industry development in three countries creates possibilities for further analysis and reference for China's emerging industry. Second, the illustration of the triangle relationship among government, market and local community in different countries helps policy makers in China reconsider and redesign an effective institutional framework for balancing the powers among indigenous community, local government and market. Institutional alignment should be listed as an important consideration during the process of the policy design of such an effective institutional framework. Originality/value: The paper presents a model to understand the dynamic co-evolution of the institution, technology and organizational fields. It confirms the role of institution in promoting emerging industry development. Particularly, it offers inspirations for the development of emerging industries in nations facing large-scale institutional transition. © Emerald Group Publishing Limited.

6.Fabricated Pictures Detection with Graph Matching


Source:ACM International Conference Proceeding Series,2020,Vol.

Abstract:Fabricating experimental pictures in research work is a serious academic misconduct, which should better be detected in the reviewing process. However, due to large number of submissions, the detection whether a picture is fabricated or reused is laborious for reviewers, and sometimes is unrecognizable with human eyes. A tool for detecting similarity between images may help to alleviate this problem. Some methods based on local feature points matching work for most of the time, while these methods may result in mess of matchings due to ignorance of global relationship between features. We present a framework to detect similar, or perhaps fabricated, pictures with the graph matching techniques. A new iterative method is proposed, and experiments show that such a graph matching technique is better than the methods based only on local features for some cases.

8.AlGaN/GaN Metal-Insulator-Semiconductor (MIS)-HFETs Based DC-DC Boost Converters with Integrated Gate Drivers

Author:Cui, M;Bu, QL;Cai, YT;Sun, RZ;Liu, W;Wen, HQ;Lam, S;Liang, YC;Mitrovic, IZ;Taylor, S;Chalker, PR;Zhao, CZ


Abstract:This study proposed a 100 kHz, 5V/11V boost converter with an integrated gate driver for a power switching device using recessed E-mode MIS-HFETs. The integrated gate driver consisting of multi-stages DCFL (Direct-Coupled FET Logic) inverters and a buffer stage, has large input swing (up to 10 V) and wide noise margin with gate dielectric, which benefits applications requiring large gate swing without any additional drivers or level shifters. The impact of transistor size on rise times and fall times have been studied. Either buffer stage or larger width of DCFL inverter can reduce rise times from 2.4 mu s to less than 0.5 mu s at 100 kHz, so the output voltage of boost converter is increased by 10 %% at a duty cycle of 0.7. However, large buffer width can result in high gate overshoot and oscillation, indicating careful design to balance switching speed and oscillation.

9.FMCW Rail-mounted SAR: porting spotlight SAR imaging from MATLAB to FPGA

Author:Melnikov, A;Le Kernec, J;Gray, D


Abstract:In this work, a low-cost laptop-based radar platform derived from the MIT open courseware has been implemented. It can perform ranging, Doppler measurement and SAR imaging using MATLAB as the processor. In this work, porting the signal processing algorithms onto a FPGA platform will be addressed as well as differences between results obtained using MAT LAB and those obtained using the FPGA platform. The target FPGA platforms were a Virtex6 DSP kit and Spartan3A starter kit, the latter was also low-cost to further reduce the cost for students to access radar technology.

11.From geometrically to algebraically described hyperbolic paraboloids: An optimisation-based analysis of the Philips Pavilion


Source:RE: Anthropocene, Design in the Age of Humans - Proceedings of the 25th International Conference on Computer-Aided Architectural Design Research in Asia, CAADRIA 2020,2020,Vol.1

Abstract:In this paper, we present a procedure to derive algebraic parameters from geometrically described truncated hyperbolic paraboloid surfaces. The procedure uses parametric modelling and optimisation to converge on close algebraic approximations of hyperbolic paraboloid geometry through a successive breakdown of vast search spaces. We illustrate this procedure with its application to the surfaces of the 1958 Philips Pavilion designed by Le Corbusier and Iannis Xenakis. This application yielded previously unavailable parametric data of this building in algebraic form. It highlights the power of the parametric design and optimisation toolkit, both in terms of automated search and epistemological enablement.

12.Post-Structural Theories and Chinese Feminist Criticism: On the Theorization of Women’s \"Subjectivity\" in the Cultural Studies of Socialist China


Source:Theoretical Studies in Literature and Art,2021,Vol.41

Abstract:Centering on the conceptualization of "subjectivity," ths article first traces the post-structural theories' impact on as well as their compex relationshp with Western feminsm. It then expores the development of the theorization of " womens subjectivity" n academic research on Chnese women and gender dscourses in socialist Chna from the 1980s. By examinng the appication of three influential theorists, Lous Althuser, Michel Foucault, and Judth Butler, n the Chnese context, ths article ntends to show the compex genealogy of "appropriating" post-structural theories for dfferent agendas of contemporary Chnese feminst criticism. Some scholars ntegrated post-structural deas nto iberal-humanst dscourses; some employed post-structuralist feminism to de-essentialize and hstoricize the analysis of "subjectivity" and "agency" of socialist Chnese women; some questioned the effectiveness of post-structural theories n studying the Chnese socialist culture from the perspective of hstorical materialism. Different research paradgms of theorizing " female subjectivity" have proven to be influenced and nformed by the changing deologies and social dscourses in Chna since the 1980s.

13.Supporting culturally and linguistically diverse students during clinical placement: strategies from both sides of the table

Author:O'Reilly, SL;Milner, J


Abstract:Background: Increasing proportions of Culturally and Linguistically Diverse (CALD) students within health professional courses at universities creates challenges in delivering inclusive training and education. Clinical placements are a core component of most health care degrees as they allow for applied learning opportunities. A research gap has been identified in regard to understanding challenges and strategies for CALD students in health professional placements. Methods: A key stakeholder approach was used to examine barriers and enablers experienced by CALD students in clinical placement. Semi-structured focus groups with healthcare students (n = 13) and clinical placement supervisors (n = 12) were employed. The focus groups were analysed using open coding and thematic analysis. Results: Three main barrier areas were identified: placement planning and preparation; teaching, assessment and feedback; and cultural and language issues. Potential solutions included addressing placement planning and preparation barriers, appropriate student placement preparation, pre-placement identification of higher risk CALD students, and diversity training for supervisors. For the barrier of teaching, assessment & feedback, addressing strategies were to: adapt student caseloads, encourage regular casual supervisor-student conversations, develop supportive placement delivery modes and structures, set expectations early, model the constructive feedback process, use visual aids, and tailor the learning environment to individual student needs. The enablers for cultural & language issues were to: build language and practical approaches for communication, raise awareness of the healthcare system (how it interacts with healthcare professions and how patients access it), and initiate mentoring programs. Conclusions: The findings suggest that teaching and learning strategies should be student-centred, aiming to promote awareness of difference and its impacts then develop appropriate responses by both student and teacher. Universities and partnering agencies, such as clinical training providers, need to provide an inclusive learning environment for students from multiple cultural backgrounds.

Abstract:A perturbation model with a single-offset microstrip feed is used in the design of a corner-deleted square patch microstrip antenna. It is shown that the use of the offset-feedsignificantly increases the size of the deleted segments and thus relaxing the fabrication tolerance. © 2010 IEEE.

15.Eco-City Comparison: West versus East


Source:Sustainability (United States),2018,Vol.11

Abstract:Sino-Singapore Tianjin Eco-city (SSTEC) in northeast China is described by Zhan and de Jong as "the best-known" of all eco-cities. As a newly created urban area, it was constructed with the intention to create a model city of, inter alia, ecologically benign technology, public transport, fresh air, and minimal carbon emissions. SSTEC is reputed to be "the first experiment to plan, build (sic) a new city in an ecological way." This article examines the nature of Tianjin's claims to eco-city status and compares and contrasts some of its key performance indicator [KPI] goals and achievements. As a control, an outline of KPIs from Tianjin Eco-city are set against the environmental and sustainable criteria derived from London, chosen given the brevity of this article. This article is not an international comparison of Eco-city Frameworks between two eco-cities; rather, it is a comparative assessment between a large, historic, non-eco-prefixed city and one of the most high-profile, new Chinese eco-cities in the world. These cities are not comparable in scale, history, culture, industry or sociopolitical structure-that is one reason for their choice. This article does not consider whether one or the other city is better or more or less compliant, but is an attempt to understand whether the "eco" label itself has merit. If benchmarks for the urban environmental performance of a city are site specific, then are they meaningful benchmarks? If non-eco-cities comply with eco-criteria, then what does the prefix tell us? The intention is to begin a process that leads to better understanding of the eco-city phenomenon and to inquire as to whether referencing eco-city labels can provide a useful interpretative mechanism for urban strategic planning. 1 2 3

16.Binding architecture: Drawing in the book


Source:Architecture and Culture,2014,Vol.2

Abstract:Architectural space is usually documented in the form of orthographic projections. These render space in a particular way and hence have limitations and specificity. The artist’s book - that is, a book made as an original work of art, with an artist or architect as author - offers a different mode of presenting documentation and reading representation. This essay explores the relationship between the paper, page and drawing - and the associated elements of a book’s sequence, structure and objecthood - to demonstrate the repercussions for architectural drawing. In doing so, it provides a material presence of architectural representation and offers the book as a site for documentating alternative operations of architecture. Through the writing of Marco Frascari, Catherine Ingraham and Stan Allen, and examples of work by Olafur Eliasson, Jonathan Safran Foer and others, the book is seen to be the site of architectural innovation, opening new territories for practice.

17.Healthcare design patterns -An internet of things approach


Source:Proceedings of the 32nd International Conference on Computers and Their Applications, CATA 2017,2017,Vol.

Abstract:The emerging Internet of Things (IoT) paradigm offers great promise for creating a global Internetbased architecture connecting humans, autonomous mobile devices, sensor networks, medical devices, and cloud computing to provide context-Aware solutions to public health whenever and wherever healthcare services are demanded. Two of the main critical areas of significance in such Healthcare IoT (HIoT) are Inhouse healthcare management for elderly people and healthcare provision in remote areas where hospital facilities do not exist. From software engineering principles for constructing a trustworthy HIoT, it is essential that the "things" in the system are dependable and reusable and the design remains extendable. This in turn will maximize the quality of service and minimize the cost of service provisioning. Motivated by this vision, this paper investigates the notion of Healthcare Design Pattern(HDP) and explains how the HDPs can be the building blocks for cyber-enabled healthcare solutions in HIoT. Three specific examples of HDPs for In-house healthcare solutions are described.

18.Emerging Issues


Source:SpringerBriefs in Applied Sciences and Technology,2014,Vol.

Abstract:This brief started by looking at the changing context for national and international healthcare systems, before reviewing the healthcare premises information, guidance and tools that underlie the approach in which sustainability is to be seen as integrated with evidence-based design rather than as divorced and separate themes. However, to understand the role these aspects play, it is also essential to consider both the historical context and, in particular, the organisational structures of the different healthcare systems whether these are national or international. This chapter discusses emerging issues from the approach that adopts design for sustainability integrated with evidence-based design. The aim is to help decision-making within the area of healthcare premises, planning and design whether this is nationally or globally. The crucial emerging issues start with the problem of definitions of ‘Evidence’ and ‘Sustainability’ but include the debates surrounding several themes: Centralisation versus Decentralisation, the nature of Public versus Private Sector Involvement, National versus International Standards to Prescription versus Performance Standards. Addressing these issues has an important bearing on the development of design for sustainability and evidence-based design as science.

19.E-commerce systems for software agents: Challenges and opportunities

Author:Tadjouddine,Emmanuel M.

Source:E-Business Issues, Challenges and Opportunities for SMEs: Driving Competitiveness,2010,Vol.

Abstract:It is hoped agent mediated e-commerce will be carried out as open systems of agents interoperating between different institutions, where different auction protocols may be in use. The authors argue that in order to put such a scenario to work, agents will need a method to automatically verify the properties of a previously unseen auction protocol. This, in turn poses the problem of automatically verifying desirable properties in order to trust a given auction mechanism. This challenge needs be addressed so that the business scenario of agent mediated e-commerce becomes a reality. In this chapter, the authors discuss salient opportunities for SMEs in addressing the issues of enabling software agents (e.g., PDAs, mobile phones) to connect to auction houses and verify desirable properties that need to hold before engaging any transactions. © 2011, IGI Global.
