Threading And Autodocumenting News Videos: A Promising Solution To Rapidly Browse News Topics, Xiao Wu, Chong-Wah Ngo, Qing Li Mar 2006

Threading And Autodocumenting News Videos: A Promising Solution To Rapidly Browse News Topics, Xiao Wu, Chong-Wah Ngo, Qing Li

Research Collection School Of Computing and Information Systems

This paper describes the techniques in threading and autodocumenting news stories according to topic themes. Initially, we perform story clustering by exploiting the duality between stories and textual-visual concepts through a co-clustering algorithm. The dependency among stories of a topic is tracked by exploring the textual-visual novelty and redundancy of stories. A novel topic structure that chains the dependencies of stories is then presented to facilitate the fast navigation of the news topic. By pruning the peripheral and redundant news stories in the topic structure, a main thread is extracted for autodocumentary

Robust Classification Of Eeg Signal For Brain-Computer Interface, Manoj Thulasidas, Cuntai Guan, Jiankang Wu Mar 2006

Robust Classification Of Eeg Signal For Brain-Computer Interface, Manoj Thulasidas, Cuntai Guan, Jiankang Wu

Research Collection School Of Computing and Information Systems

We report the implementation of a text input application (speller) based on the P300 event related potential. We obtain high accuracies by using an SVM classifier and a novel feature. These techniques enable us to maintain fast performance without sacrificing the accuracy, thus making the speller usable in an online mode. In order to further improve the usability, we perform various studies on the data with a view to minimizing the training time required. We present data collected from nine healthy subjects, along with the high accuracies (of the order of 95% or more) measured online. We show that the …

Crosscutting Score: An Indicator Metric For Aspect Orientation, Subhajit Datta Mar 2006

Crosscutting Score: An Indicator Metric For Aspect Orientation, Subhajit Datta

Research Collection School Of Computing and Information Systems

Aspect Oriented Programming (AOP) provides powerful techniques for modeling and implementing enterprise software systems. To leverage its full potential, AOP needs to be perceived in the context of existing methodologies such as Object Oriented Programming (OOP). This paper addresses an important question for AOP practitioners - how to decide whether a component is best modeled as a class or an aspect? Towards that end, we present an indicator metric, the Crosscutting Score and a method for its calculation and interpretation. We will illustrate our approach through a sample calculation.

Employee Screening: Theory And Evidence, Fali Huang, Peter Cappelli Mar 2006

Employee Screening: Theory And Evidence, Fali Huang, Peter Cappelli

Research Collection School Of Economics

Arguably the fundamental problem faced by employers is how to elicit effort from employees. Most models suggest that employers meet this challenge by monitoring employees carefully to prevent shirking. But there is another option that relies on heterogeneity across employees, and that is to screen job candidates to find workers with a stronger work ethic who require less monitoring. This should be especially useful in work systems where monitoring by supervisors is more difficult, such as teamwork systems. We analyze the relationship between screening and monitoring in the context of a principal-agent model and test the theoretical results using a …

Caps: Energy-Efficient Processing Of Continuous Aggregate Queries In Sensor Networks, Wen Hu, Archan Misra, Rajiv Shorey Mar 2006

Caps: Energy-Efficient Processing Of Continuous Aggregate Queries In Sensor Networks, Wen Hu, Archan Misra, Rajiv Shorey

Research Collection School Of Computing and Information Systems

In this paper, we design and evaluate an energy efficient data retrieval architecture for continuous aggregate queries in wireless sensor networks. We show how the modification of precision in one sensor affects the sample-reporting frequency of other sensors, and how the precisions of a group of sensors may be collectively modified to achieve the target quality of information (QoI) with higher energy-efficiency. The proposed collective adaptive precision setting (CAPS) architecture is then extended to exploit the observed temporal correlation among successive sensor samples for even greater energy efficiency. Detailed simulations with synthetic and real data traces demonstrate how the combination …

Splash: Systematic Proteomics Laboratory Analysis And Storage Hub, Siaw Ling Lo, You Tao, Qingsong Lin, Shashikant B. Joshi, Maxey Chung, Choy Leong Hew

Research Collection School Of Computing and Information Systems

In the field of proteomics, the increasing difficulty to unify the data format, due to the different platforms/instrumentation and laboratory documentation systems, greatly hinders experimental data verification, exchange, and comparison. Therefore, it is essential to establish standard formats for every necessary aspect of proteomics data. One of the recently published data models is the proteomics experiment data repository [Taylor, C. F., Paton, N. W., Garwood, K. L., Kirby, P. D. et al., Nat. Biotechnol. 2003, 21, 247-254]. Compliant with this format, we developed the systematic proteomics laboratory analysis and storage hub (SPLASH) database system as an informatics infrastructure to support …

Extending Economic Boundaries And Exporting Expertise: New Evidence On Singapore's Gambit In Indonesia, Vietnam And India, Caroline Yeoh, Siang Yeung Wong Feb 2006

Extending Economic Boundaries And Exporting Expertise: New Evidence On Singapore's Gambit In Indonesia, Vietnam And India, Caroline Yeoh, Siang Yeung Wong

Research Collection Lee Kong Chian School Of Business

Singapore's regionalization stratagem led to the establishment of industrial parks in China, India and several South-East Asian countries. The strategic intent behind these overseas projects was twofold: exporting Singapore's competencies such as management know-how, technological capabilities and corrupt-free administration to regions where such positive factors were lacking and secondly, exploiting comparative advantages that each region had to offer. This paper 1 revisits Singapore's flagship projects in Indonesia, Vietnam and India. Evidence from on-site surveys and interviews are presented. This paper contends that progress in these privileged investment zones remains stymied by particular dependencies and challenges in the host environments.

Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding Feb 2006

Government Ownership And The Performance Of Government-Linked Companies: The Case Of Singapore, James Ang, David K. Ding

Research Collection Lee Kong Chian School Of Business

In an emerging economy, the alternative to government control is often no governance. We investigate the governance structure of government-linked companies (GLCs) in Singapore under the ownership/control structure of Temasek Holdings, the government holding entity, which typically owns substantial cash flow rights but disproportional control rights and exercises no operational control. We compare the financial and market performance of GLCs with non-GLCs, where each has a different set of governance structure, the key difference being government ownership. We show that Singaporean GLCs have higher valuations and better corporate governance than a control group of non-GLCs. The results hold even when …

Hungary: Holding Back The Tiers, Kenneth Benoit Feb 2006

Hungary: Holding Back The Tiers, Kenneth Benoit

Research Collection School of Social Sciences

Hungary has a particularly complicated electoral system: a type of mixed system that incorporates three tiers of seat allocation, the use of a proportional allocation formula, and the allocation of a number of seats by a two-round system in single-member constituencies. Examination of the strategic incentives facing parties explains some surprising outcomes, such as the majoritarian impact on the party system and the possibility of the second strongest party in votes becoming the strongest in seats. Despite its complexity and alleged shortcomings, it is unlikely to be abandoned; it serves the interests of the largest parties, and these effectively wield …

Music And Moral Geographies: Constructions Of "Nation" And Identity In Singapore, Lily Kong Feb 2006

Music And Moral Geographies: Constructions Of "Nation" And Identity In Singapore, Lily Kong

Research Collection School of Social Sciences

In this paper, I attempt to pull together sociological and geographical perspectives in the study of music to understand the ways in which pop and rock music are socio-cultural products with political and moral meanings and implications. I examine state engineering of moral panics, focusing on a case study of pop and rock music in post-independence Singapore. Such engineering is aimed at political and ideological ends, in particular, "nation"- building outcomes. In engineering moral panics through both discursive and legislative acts, the contours of a moral geography are delineated at various spatial scales. First, at the scale of the national …

Central Asia's Transition After Fifteen Years: Growth And Policy Choices, Malcolm Dowling, Ganeshan Vignaraja Feb 2006

Central Asia's Transition After Fifteen Years: Growth And Policy Choices, Malcolm Dowling, Ganeshan Vignaraja

Research Collection School Of Economics

This paper presents a coherent and systematic analysis of the collapse and subsequent revival of the Central Asian Republics (CARs) since 1990. The focus is on the pattern of growth and structural change during the cycle of decline and subsequent revival in the CARs which have been inadequately analyzed in the literature on transition. The paper relates economic performance to initial conditions, country characteristics and policies. Within this framework, it proposes a simple typology of policies (including a new Type III set of policies on regional cooperation and industrial competitiveness) and relates them to the cycle of decline and revival …

Competition Policy In Indonesia, Malcolm Dowling Feb 2006

Competition Policy In Indonesia, Malcolm Dowling

Research Collection School Of Economics

The Indonesian economy was dominated by the government in the decades of the 1970s and 1980s through its control of major mining, manufacturing and agricultural activities. Hill (2000) estimates that as much as 40% of non-agricultural GDP was accounted for by government entities in the late 1980s There were still a lot of government corporations up until the late 1980s and early 1990s and governmental control over the banking system was still substantial.

Scalable Authentication Of Mpeg-4 Streams, Yongdong Wu, Robert H. Deng Feb 2006

Scalable Authentication Of Mpeg-4 Streams, Yongdong Wu, Robert H. Deng

Research Collection School Of Computing and Information Systems

This paper presents three scalable and efficient schemes for authenticating MPEG-4 streams: the Flat Authentication Scheme, the Progressive Authentication Scheme, and the Hierarchical Authentication Scheme. All the schemes allow authentication of MPEG-4 streams over lossy networks by integrating seamlessly digital signatures and erasure correction coding with MPEG-4's fine granular scalability. A prominent feature of our schemes is their "sign once, verify many ways" property, i.e., they generate only one digital signature per compressed MPEG-4 object group, but allow clients to verify the authenticity of any down-scaled version of the original signed object group.

Energy Efficiency And Capacity For Tcp Traffic In Multi-Hop Wireless Networks, Sorav Bansal, Rajeev Shorey, Rajeev Gupta, Archan Misra Feb 2006

Energy Efficiency And Capacity For Tcp Traffic In Multi-Hop Wireless Networks, Sorav Bansal, Rajeev Shorey, Rajeev Gupta, Archan Misra

Research Collection School Of Computing and Information Systems

We study the performance metrics associated with TCP-regulated traffic in multi-hop, wireless networks that use a common physical channel (e.g., IEEE 802.11). In contrast to earlier analyses, we focus simultaneously on two key operating metrics—the energy efficiency and the transport-layer (TCP) throughput. Using analysis and simulations, we show how these metrics are strongly influenced by the radio transmission range of individual nodes. Due to tradeoffs between the individual packet transmission energy and the likelihood of retransmissions, the total energy consumption is a convex function of the number of hops (and hence, of the transmission range). On the other hand, the …

Design Synthesis From Interaction And State-Based Specifications, Jun Sun, Jin Song Dong Jan 2006

Design Synthesis From Interaction And State-Based Specifications, Jun Sun, Jin Song Dong

Research Collection School Of Computing and Information Systems

Interaction-based and state-based modeling are two complementary approaches of behavior modeling. The former focuses on global interactions between system components. The latter concentrates on the internal states of individual components. Both approaches have been proven useful in practice. One challenging and important research objective is to combine the modeling power of both effectively and then use the combination as the basis for automatic design synthesis. We present a combination of interaction-based and state-based modeling, namely, Live Sequence Charts and Z, for system specification. We then propose a way of generating distributed design from the combinations. Our approach handles systems with …

Fabrication-Tolerant Active-Passive Integration Scheme For Vertically-Coupled Microring Resonators, Chyng Wen Tee, Ka Williams, Rv Penty, Ih White Jan 2006

Fabrication-Tolerant Active-Passive Integration Scheme For Vertically-Coupled Microring Resonators, Chyng Wen Tee, Ka Williams, Rv Penty, Ih White

Research Collection Lee Kong Chian School Of Business

The large-scale photonic integration of microring resonators in three dimensions made possible by recent developments in vertical coupling and wafer bonding technology is shown to be sensitive to lateral mask misalignment for the ring and bus waveguides introduced during the fabrication process. For a typical 20-μm radius, vertically coupled microring calculations reveal a linear relationship between deviation in the coupling coefficient and lateral misalignment. A coupling coefficient reduction of 50% is predicted for a lateral misalignment of 0.3 μm, which is typical for an alignment accuracy limited by the current state-of-the-art mask alignment process. The use of a wide multimode …

Realizing The Potential Of The Ambidextrous Firm, James Arthur Robins Jan 2006

Realizing The Potential Of The Ambidextrous Firm, James Arthur Robins

Research Collection Lee Kong Chian School Of Business

Sustaining innovation in the face of pressures to be cost-competitive and make effective use of existing resources is not a new challenge, but recent acceleration of competition has pushed this issue high on the agenda for managers and researchers. Organizing and managing the “ambidextrous” company – a firm that excel in exploring new areas of productive knowledge and exploiting existing capabilities – has emerged as a major concern of strategic management. In this paper, we explore coordination problems that make it difficult for firms to realize their potential as ambidextrous competitors. Organizations may possess superior skills for both exploration and …

Under-Pricing And Long-Run Performance Of Initial Public Offerings In Developing Markets, Sze Wei Daniel Ong

Dissertations and Theses Collection (Open Access)

The transition from being a private company to a public one is one of the most important events in the life of a firm. It is also one of particular interest to institutional investors, and the transition is facilitated through the initial public offering (IPO) process. The IPO provides a fresh source of capital that is critical to the growth of the firm and provides the founder and other shareholders such as venture capitalists a liquid market for their shares. From an institutional investor's perspective, the IPO provides an opportunity to share in the rewards of the growth of the …

The Role Of European Governments In The Digital Economy, Arnoud Cyriel Leo De Meyer Jan 2006

The Role Of European Governments In The Digital Economy, Arnoud Cyriel Leo De Meyer

Research Collection Lee Kong Chian School Of Business

What is the role of government in the digital economy? It is not our intention to go into an in-depth ideological debate on whether governments should intervene in the business sector. We will try to adopt a pragmatic approach and explore what already happens in practice. It is up to the reader to make a judgment to what extent the governments should be involved in the ICT sector. There is enough indication that, due to network externality effects, governments need to take on an active role in stimulating an e-environment to jump-start the move toward a higher level of e-readiness.In …

Have We Taught Our Students The Right Stuff?, Jaydeep Balakrishnan, Kum Khiong Yang Jan 2006

Have We Taught Our Students The Right Stuff?, Jaydeep Balakrishnan, Kum Khiong Yang

Research Collection Lee Kong Chian School Of Business

Operations Management involves managing the resources that are required to convert inputs to outputs. These resources include materials, capital and people which requires decision making within the operations function to be cross functional (Schroeder, 2000). The resulting impact is that whenever an operations manager makes a decision, he or she should be cognizant of its impact on other areas within the firm, such as finance, marketing and human resources, as well as the external partners such as suppliers and customers. Our question is whether Production and Operations Management (POM) educators are training students adequately to make the necessary cross functional …

Little Understood Knowledge Trap, Hans-Dieter Evers, Solvay Gerke, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

As knowledge increases, we realise how much else we do not know. Successful research always results in new questions. Any knowledge economy must be aware of such unknowns if it is to expand further through research and development. Debate on bridging the digital divide does not take this factor into account. Many of the strategies currently preached are misplaced.

The Roles Of Digital Libraries In Teaching And Learning Geography, Chew-Hung Chang, John Hedberg, Tiong-Sa Teh, Ee Peng Lim Jan 2006

The Roles Of Digital Libraries In Teaching And Learning Geography, Chew-Hung Chang, John Hedberg, Tiong-Sa Teh, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Adopting a problem-centred approach helps students to learn Geography more effectively as they are able to identify and generalize about where different resources or activities are spatially located and they learn to associate certain patterns and processes with geographical changes. In an era where web-based student-centred inquiry is gaining popularity as a mode of learning Geography, the role of digital libraries as delivery trucks (in Clark’s terminology, 1983) needs to be better understood. An obvious affordance of the digital library is that it organizes information around themes for problems to be solved. This paper describes a developmental project to build …
