In Defense Of The No Discharge After Notice Rule: A Reply, Chee Ho Tham Jan 2010

In Defense Of The No Discharge After Notice Rule: A Reply, Chee Ho Tham

Research Collection Yong Pung How School Of Law

Mr Trukhtanov has made his own summary of and response to my own account of equitable (and statutory) assignment, and how notice of assignment operates within them. Having been reminded of how the cases on the topic are usually understood, readers will have to make up their own minds. While there is, always, room for further thought, it is important not to lose sight of two fairly important distinctions. Where A is the debtor, B is the creditor, and C is an assignee to whom B has assigned the chose in action arising from A’s debt obligation, a distinction should …

Updating The Electronic Transactions Act? Australia's Accession To The Un Convention On The Use Of Electronic Communications In International Contracts 2005, Eliza Karolina Mik Jan 2010

Updating The Electronic Transactions Act? Australia's Accession To The Un Convention On The Use Of Electronic Communications In International Contracts 2005, Eliza Karolina Mik

Research Collection Yong Pung How School Of Law

This article discusses the Australian Government’s proposal to accede to the United Nations Convention on the Use of Electronic Communications in International Contracts as well as certain amendments to existing Australian electronic transactions legislation, i.e. the Electronic Transactions Act (Commonwealth) 1999 (”ETA”) and its state equivalents. Without going into a detailed discussion of all suggested amendments, this article focuses on those recommendations, which affect the area of contract formation, in particular: the use of automated systems in on-line transactions and the determination of the time the contract comes into existence. A critical review of the proposed changes reveals that their …


Evaluating The Impact Of The Un Convention On The Use Of Electronic Communications In International Contracts On Domestic Contract Law: The Singapore Example, Eliza Mik Jan 2010

Evaluating The Impact Of The Un Convention On The Use Of Electronic Communications In International Contracts On Domestic Contract Law: The Singapore Example, Eliza Mik

Research Collection Yong Pung How School Of Law

The United Nations Commission on International Trade Law (UNCITRAL) Convention on the Use of Electronic Communications in International Contracts (CUECIC or Convention) was adopted on 23 November 2005. Its essential objective is to establish uniform rules intended to “remove obstacles to the use of electronic communications in international contracts, including obstacles that might result from the operation of existing international trade law instruments, with a view to enhancing legal certainty and commercial predictability.” The Convention relies on the UNCITRAL Model Law on Electronic Commerce (MLEC), which constitutes an e-commerce flagship project dating back to 1995. It also resembles UNCITRAL’s Convention …


Understanding Performance Ratings: Dynamic Performance, Attributions, And Rating Purpose, Jochen Reb, Gary J. Greguras Jan 2010

Understanding Performance Ratings: Dynamic Performance, Attributions, And Rating Purpose, Jochen Reb, Gary J. Greguras

Research Collection Lee Kong Chian School Of Business

The present two studies integrate and extend the literatures on dynamic performance, performance attributions, and rating purpose, making several important contributions. First, examining attributions of dynamic performance, Study 1 predicted that performance mean and trend would affect judged ratee ability and effort and that performance variation would affect locus of causality; both predictions were supported by the results. Second, investigating the interaction between dynamic performance and rating purpose. Study 2 predicted that performance mean would have a stronger impact on administrative than on developmental ratings, whereas performance trend and variation would have a stranger impact on developmental than on administrative …


Nested Coloured Timed Petri Nets For Production Configuration Of Product Families, Lianfeng Zhang, Brian Rodrigues Jan 2010

Nested Coloured Timed Petri Nets For Production Configuration Of Product Families, Lianfeng Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Production configuration is as an effective technique to deal with product variety while maintaining production stability and efficiency. It involves a diverse set of process elements (e.g., machines, operations), a high variety of component parts and assemblies and many constraints arising from product and process variety. Production configuration entails the selection and subsequent arrangement of process elements into complete production processes and the final evaluation of configured multiple alternatives. To better understand production configuration and its implementation, we study the underlying logic for configuring production processes using a dynamic modelling and visualisation approach. This is accomplished by developing a new …


The Constructive Trust In Singapore: Five Persistent Puzzles, Hang Wu Tang Jan 2010

This paper investigates some persistent difficulties surrounding the constructive trust. The five persistent puzzles relating to the constructive trust that are considered in this paper are: the terminology puzzle, the institutional and remedial puzzle, the explanatory puzzle, the bankruptcy puzzle and the Torrens puzzle. It is the author’s thesis that these five enduring puzzles must be addressed and ultimately unravelled in order to ensure the coherent development of the law in this area.


Scalable Multi-Core Model Checking Fairness Enhanced Systems, Yang Liu, Jun Sun, Jin Song Dong Dec 2009

Scalable Multi-Core Model Checking Fairness Enhanced Systems, Yang Liu, Jun Sun, Jin Song Dong

Research Collection School Of Computing and Information Systems

Rapid development in hardware industry has brought the prevalence of multi-core systems with shared-memory, which enabled the speedup of various tasks by using parallel algorithms. The Linear Temporal Logic (LTL) model checking problem is one of the difficult problems to be parallelized or scaled up to multi-core. In this work, we propose an on-the-fly parallel model checking algorithm based on the Tarjan’s strongly connected components (SCC) detection algorithm. The approach can be applied to general LTL model checking or with different fairness assumptions. Further, it is orthogonal to state space reduction techniques like partial order reduction. We enhance our PAT …


Asian Maths Whizz And Talkative Females: How Stereotypes Can Actually Boost Performance, Knowledge@Smu Dec 2009

Asian Maths Whizz And Talkative Females: How Stereotypes Can Actually Boost Performance, Knowledge@Smu

Knowledge@SMU

Nobody likes to be pigeonholed or reduced to a single stereotype. One reason could be because we believe ourselves to be products of multiple stereotypes: a combination of identities, such as "Asian", "female", "lawyer", "Gen X", "Christian", "Chinese", etc. While these labels connect us to like-individuals, they can also carry all sorts of connotations and expectations – positive, neutral and negative. For example, an Asian might be expected to outperform a non-Asian at mathematics because of stereotypes that Asians are mathematically inclined. Will such undue expectations affect the Asian's performance outcome? Research studies point to a 'Yes'.


The Role Of Is Project Critical Success Factors: A Revelatory Case, Cecil Eng Huang Chua, Wee-Kiat Lim Dec 2009

The Role Of Is Project Critical Success Factors: A Revelatory Case, Cecil Eng Huang Chua, Wee-Kiat Lim

CCX Research

Research in Critical Success Factors (CSFs) of Enterprise Systems (ES) projects has identified numerous practitioner governance mechanisms for ensuring project success. However, such research has not developed a theory of why certain critical success factors encourage project success. Our research develops such theory on a case study where even though the levels of several critical success factors were weak, the project nevertheless succeeded. Specifically, the logistics ES project succeeded even though there was (1) only marginal top management support, (2) low key user commitment, and (3) change management, training and other critical aspects of user management and communication were not …


Cyber Attacks: Does Physical Boundary Matter?, Qiu-Hong Wang, Seung-Hyun Kim Dec 2009

Cyber Attacks: Does Physical Boundary Matter?, Qiu-Hong Wang, Seung-Hyun Kim

Research Collection School Of Computing and Information Systems

Information security issues are characterized with interdependence. Particularly, cyber criminals can easily cross national boundaries and exploit jurisdictional limitations between countries. Thus, whether cyber attacks are spatially autocorrelated is a strategic issue for government authorities and a tactic issue for insurance companies. Through an empirical study of cyber attacks across 62 countries during the period 2003-2007, we find little evidence on the spatial autocorrelation of cyber attacks at any week. However, after considering economic opportunity, IT infrastructure, international collaboration in enforcement and conventional crimes, we find strong evidence that cyber attacks were indeed spatially autocorrelated as they moved over time. …


Wake Up Or Fall Asleep: Value Implication Of Trusted Computing, Nan Hu, Jianhui Huang, Ling Liu, Yingjiu Li, Dan Ma Dec 2009

Wake Up Or Fall Asleep: Value Implication Of Trusted Computing, Nan Hu, Jianhui Huang, Ling Liu, Yingjiu Li, Dan Ma

Research Collection School Of Computing and Information Systems

More than 10 years have passed since trusted computing (TC) technology was introduced to the market; however, there is still no consensus about its value. The increasing importance of user and enterprise security and the security promised by TC, coupled with the increasing tension between the proponents and the opponents of TC, make it timely to investigate the value relevance of TC in terms of both capital market and accounting performance. Based on both price and volume studies, we found that news releases related to the adoption of the TC technology had no information content. All investors, regardless of whether …


Denial-Of-Service Attacks On Host-Based Generic Unpackers, Limin Liu, Jiang Ming, Zhi Wang, Debin Gao, Chunfu Jia Dec 2009

Denial-Of-Service Attacks On Host-Based Generic Unpackers, Limin Liu, Jiang Ming, Zhi Wang, Debin Gao, Chunfu Jia

Research Collection School Of Computing and Information Systems

With the advance of packing techniques, a few generic and automatic unpackers have been proposed. These unpackers are designed to automatically unpack packed binaries without specific knowledge of the packing techniques used. In this paper, we present an automatic packer with which packed malware forges spurious unpacking behaviors that lead to a denial-of-service attack on host-based generic unpackers. We present the design, implementation, and evaluation of the proposed packer and malware produced using the proposed packer, and show the success of denial-of-service attacks on host-based generic unpackers.


On Strategies For Imbalanced Text Classification Using Svm: A Comparative Study, Aixin Sun, Ee Peng Lim, Ying Liu Dec 2009

On Strategies For Imbalanced Text Classification Using Svm: A Comparative Study, Aixin Sun, Ee Peng Lim, Ying Liu

Research Collection School Of Computing and Information Systems

Many real-world text classification tasks involve imbalanced training examples. The strategies proposed to address the imbalanced classification (e.g., resampling, instance weighting), however, have not been systematically evaluated in the text domain. In this paper, we conduct a comparative study on the effectiveness of these strategies in the context of imbalanced text classification using Support Vector Machines (SVM) classifier. SVM is the interest in this study for its good classification accuracy reported in many text classification tasks. We propose a taxonomy to organize all proposed strategies following the training and the test phases in text classification tasks. Based on the taxonomy, …


Enabling Secure Secret Updating For Unidirectional Key Distribution In Rfid-Enabled Supply Chains, Shaoying Cai, Tieyan Li, Changshe Ma, Yingjiu Li, Robert H. Deng Dec 2009

Enabling Secure Secret Updating For Unidirectional Key Distribution In Rfid-Enabled Supply Chains, Shaoying Cai, Tieyan Li, Changshe Ma, Yingjiu Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

In USENIX Security 08, Juels, Pappu and Parno proposed a secret sharing based mechanism to alleviate the key distribution problem in RFID-enabled supply chains. Compared to existing pseudonym based RFID protocols, the secret sharing based solution is more suitable for RFID-enabled supply chains since it does not require a database of keys be distributed among supply chain parties for secure ownership transfer of RFID tags. However, this mechanism cannot resist tag tracking and tag counterfeiting attacks in supply chain systems. It is also not convenient for downstream supply chain parties to adjust the size of RFID tag collections in recovering …


A Robust Damage Assessment Model For Corrupted Database Systems, Ge Fu, Hong Zhu, Yingjiu Li Dec 2009

A Robust Damage Assessment Model For Corrupted Database Systems, Ge Fu, Hong Zhu, Yingjiu Li

Research Collection School Of Computing and Information Systems

An intrusion tolerant database uses damage assessment techniques to detect damage propagation scales in a corrupted database system. Traditional damage assessment approaches in a intrusion tolerant database system can only locate damages which are caused by reading corrupted data. In fact, there are many other damage spreading patterns that have not been considered in traditional damage assessment model. In this paper, we systematically analyze inter-transaction dependency relationships that have been neglected in the previous research and propose four different dependency relationships between transactions which may cause damage propagation. We extend existing damage assessment model based on the four novel dependency …


Adaptive Type-2 Fuzzy Maintenance Advisor For Offshore Power Systems, Zhaoxia Wang, C. S. Chang, Fan Yang, W. W. Tan Dec 2009

Adaptive Type-2 Fuzzy Maintenance Advisor For Offshore Power Systems, Zhaoxia Wang, C. S. Chang, Fan Yang, W. W. Tan

Research Collection School Of Computing and Information Systems

Proper maintenance strategies are very desirable for minimizing the operational and maintenance costs of power systems without sacrificing reliability. Condition-based maintenance has largely replaced time-based maintenance because of the former's potential economic benefits. As offshore substations are often remotely located, they experience more adverse environments, higher failures, and therefore need more powerful analytical tools than their onshore counterpart. As reliability information collected during operation of an offshore substation can rarely avoid uncertainties, it is essential to obtain consistent estimates of reliability measures under changing environmental and operating conditions. Some attempts with type-1 fuzzy logic were made with limited success in …


On The Untraceability Of Anonymous Rfid Authentication Protocol With Constant Key-Lookup, Bing Liang, Yingjiu Li, Tieyan Li, Robert H. Deng Dec 2009

On The Untraceability Of Anonymous Rfid Authentication Protocol With Constant Key-Lookup, Bing Liang, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

In ASIACCS'08, Burmester, Medeiros and Motta proposed an anonymous RFID authentication protocol (BMM protocol [2]) that preserves the security and privacy properties, and achieves better scalability compared with other contemporary approaches. We analyze BMM protocol and find that some of security properties (especial untraceability) are not fulfilled as originally claimed. We consider a subtle attack, in which an adversary can manipulate the messages transmitted between a tag and a reader for several continuous protocol runs, and can successfully trace the tag after these interactions. Our attack works under a weak adversary model, in which an adversary can eavesdrop, intercept and …


The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan Dec 2009

The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan

Research Collection School of Social Sciences

Maps are an important site of the production and consumption of the national image. This essay examines modern Chinese maps to show how the very material borders between foreign and domestic space are the outgrowth of the symbolic workings of historical geography and the conventions of Chinese cartography. These maps do much more than celebrate the extent of Chinese sovereignty; they also mourn the loss of national territories through a cartography of national humiliation. The goal of this essay is to shift our attention from the diplomatic issues of international borders to examine what Chinese maps of China can tell …


Empirical Likelihood In Missing Data Problems, Jing Qin, Biao Zhang, Denis H. Y. Leung Dec 2009

Empirical Likelihood In Missing Data Problems, Jing Qin, Biao Zhang, Denis H. Y. Leung

Research Collection School Of Economics

Missing data is a ubiquitous problem in medical and social sciences. It is well known that inferences based only on the complete data may not only lose efficiency, but may also lead to biased results if the data is not missing completely at random (MCAR). The inverse-probability weighting method proposed by Horvitz and Thompson (1952) is a popular alternative when the data is not MCAR. The Horvitz–Thompson method, however, is sensitive to the inverse weights and may suffer from loss of efficiency. In this paper, we propose a unified empirical likelihood approach to missing data problems and explore the use …


Coherent Phrase Model For Efficient Image Near-Duplicate Retrieval, Yiqun Hu, Xiangang Cheng, Liang-Tien Chia, Xing Xie, Deepu Rajan, Ah-Hwee Tan Dec 2009

Coherent Phrase Model For Efficient Image Near-Duplicate Retrieval, Yiqun Hu, Xiangang Cheng, Liang-Tien Chia, Xing Xie, Deepu Rajan, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

This paper presents an efficient and effective solution for retrieving image near-duplicate (IND) from image database. We introduce the coherent phrase model which incorporates the coherency of local regions to reduce the quantization error of the bag-of-words (BoW) model. In this model, local regions are characterized by visual phrase of multiple descriptors instead of visual word of single descriptor. We propose two types of visual phrase to encode the coherency in feature and spatial domain, respectively. The proposed model reduces the number of false matches by using this coherency and generates sparse representations of images. Compared to other method, the …


To Trust Or Not To Trust? Predicting Online Trusts Using Trust Antecedent Framework, Viet-An Nguyen, Ee Peng Lim, Jing Jiang, Aixin Sun Dec 2009

To Trust Or Not To Trust? Predicting Online Trusts Using Trust Antecedent Framework, Viet-An Nguyen, Ee Peng Lim, Jing Jiang, Aixin Sun

Research Collection School Of Computing and Information Systems

This paper analyzes the trustor and trustee factors that lead to inter-personal trust using a well studied Trust Antecedent framework in management science. To apply these factors to trust ranking problem in online rating systems, we derive features that correspond to each factor and develop different trust ranking models. The advantage of this approach is that features relevant to trust can be systematically derived so as to achieve good prediction accuracy. Through a series of experiments on real data from Epinions, we show that even a simple model using the derived features yields good accuracy and outperforms MoleTrust, a trust …


Insights Into Malware Detection And Prevention On Mobile Phones, Qiang Yan, Yingjiu Li, Tieyan Li, Robert H. Deng Dec 2009

Insights Into Malware Detection And Prevention On Mobile Phones, Qiang Yan, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

The malware threat for mobile phones is expected to increase with the functionality enhancement of mobile phones. This threat is exacerbated with the surge in population of smart phones instilled with stable Internet access which provides attractive targets for malware developers. Prior research on malware protection has focused on avoiding the negative impact of the functionality limitations of mobile phones to keep the performance cost within the limitations of mobile phones. Being different, this paper investigates the positive impact of these limitations on suppressing the development of mobile malware. We study the state-of-the-art mobile malware, as well as the progress …


A New Approach For Anonymous Password Authentication, Yanjiang Yang, Jianying Zhou, Jian Weng, Feng Bao Dec 2009

A New Approach For Anonymous Password Authentication, Yanjiang Yang, Jianying Zhou, Jian Weng, Feng Bao

Research Collection School Of Computing and Information Systems

Anonymous password authentication reinforces password authentication with the protection of user privacy. Considering the increasing concern of individual privacy nowadays, anonymous password authentication represents a promising privacy-preserving authentication primitive. However, anonymous password authentication in the standard setting has several inherent weaknesses, making its practicality questionable. In this paper, we propose a new and efficient approach for anonymous password authentication. Our approach assumes a different setting where users do not register their passwords to the server; rather, they use passwords to protect their authentication credentials. We present a concrete scheme, and get over a number of challenges in securing password-protected credentials …


Duol: A Double Updating Approach For Online Learning, Peilin Zhao, Steven C. H. Hoi, Rong Jin Dec 2009

Duol: A Double Updating Approach For Online Learning, Peilin Zhao, Steven C. H. Hoi, Rong Jin

Research Collection School Of Computing and Information Systems

In most online learning algorithms, the weights assigned to the misclassified examples (or support vectors) remain unchanged during the entire learning process. This is clearly insufficient since when a new misclassified example is added to the pool of support vectors, we generally expect it to affect the weights for the existing support vectors. In this paper, we propose a new online learning method, termed Double Updating Online Learning, or DUOL for short. Instead of only assigning a fixed weight to the misclassified example received in current trial, the proposed online learning algorithm also tries to update the weight for one …


Learning Bregman Distance Functions And Its Application For Semi-Supervised Clustering, Lei Wu, Rong Jin, Steven C. H. Hoi, Jianke Zhu, Nenghai Yu Dec 2009

Learning Bregman Distance Functions And Its Application For Semi-Supervised Clustering, Lei Wu, Rong Jin, Steven C. H. Hoi, Jianke Zhu, Nenghai Yu

Research Collection School Of Computing and Information Systems

Learning distance functions with side information plays a key role in many machine learning and data mining applications. Conventional approaches often assume a Mahalanobis distance function. These approaches are limited in two aspects: (i) they are computationally expensive (even infeasible) for high dimensional data because the size of the metric is in the square of dimensionality; (ii) they assume a fixed metric for the entire input space and therefore are unable to handle heterogeneous data. In this paper, we propose a novel scheme that learns nonlinear Bregman distance functions from side information using a nonparametric approach that is similar to …


Why Egregious Errors Of Law May Yet Justify A Refusal Of Enforcement Under The 'New York Convention', Seng Wei, Edward Ti Dec 2009

Why Egregious Errors Of Law May Yet Justify A Refusal Of Enforcement Under The 'New York Convention', Seng Wei, Edward Ti

Research Collection Yong Pung How School Of Law

Parties on the losing side in international arbitration have long argued that an error of law is a defence to the enforcement of foreign awards. Citing article V(2)(b) of the New York Convention, such parties have argued that a manifest error of law is a violation of public policy. While national courts have generally paid little heed to this line of argument, this article seeks to raise the possibility that there may yet be the exceedingly rare instance in which a court should preclude enforcing an award marred by a hideous error of law. Limited review of an arbitrator's application …


In Support Of A Cashless Future, Researchers Recreate A Cash-Like Experience, Knowledge@Smu Nov 2009

In Support Of A Cashless Future, Researchers Recreate A Cash-Like Experience, Knowledge@Smu

Knowledge@SMU

The mobile phone is piece of technology so loved, that some have referred to it as a “phantom limb”. To personalise and get the most out of this “limb”, people have been known to spend lots of time and money, decorating their precious phones with screen protectors, fancy ringtones, wallpapers, themes and ‘apps’. Many have even been caught fiddling with this device while driving! With a national mobile penetration rate of close to 140 percent (which suggests some people may have more “limbs” than others), it seems only natural to fantasise about incorporating the mobile phone into other favourite pastimes, …
