Exclusive And Inclusive Semileptonic Decays Of B Mesons To D Mesons, R. Fulton, M. Thulasidas Jan 1991

Exclusive And Inclusive Semileptonic Decays Of B Mesons To D Mesons, R. Fulton, M. Thulasidas

Research Collection School Of Computing and Information Systems

We report new measurements of the branching fractions B ( B − → D 0 l − ¯ ν ) , B ( ¯ B 0 → D + l − ¯ ν ) , and B ( B − → D * 0 l − ¯ ν ) . Combining these results with our previous measurement of B ( ¯ B 0 → D * + l − ¯ ν ) , we find that the ratio of semileptonic widths for final states with a vector meson and pseudoscalar meson is ( 2.6 + 1.1 + 1.0 − 0.6 …

Fuzzy Neural Logic Network And Its Learning Algorithms, Fiona Fui-Hoon Nah, Nah Fiona Jan 1991

Fuzzy Neural Logic Network And Its Learning Algorithms, Fiona Fui-Hoon Nah, Nah Fiona

Research Collection School Of Computing and Information Systems

The paper introduces the basic features of fuzzy neural logic network. Each fuzzy neural logic network model is trained from a set of knowledge in the form of examples using one of the three learning algorithms introduced. These three learning algorithms are the delta rule controlled learning algorithm and two mathematical construction algorithms, namely, the local learning method and the global learning method. Once the fuzzy neural logic network model is constructed, it is ready to accept any unknown input from the user. With a low percentage of mismatched features, output solution can be obtained.

Inclusive Production Of The Charmed Baryon C+ From E+E- Annihilations At S=10.55 Gev, P. Avery, Manoj Thulasidas Jan 1991

Inclusive Production Of The Charmed Baryon C+ From E+E- Annihilations At S=10.55 Gev, P. Avery, Manoj Thulasidas

Research Collection School Of Computing and Information Systems

We report results on inclusive production of the charmed baryon Λc+ from e+e− annihilations at √s=10.5 GeV. Measurements are presented of the inclusive cross section times branching fraction for the continuum production of Λc+ as observed in six different decay modes, and of a new, improved value of the Λc+ mass. The inclusive cross section times the branching fraction into pK−π+ is measured to be 10.0±1.5±1.5 pb summed over all xp. The branching fractions of Λc+ into p¯K0, p¯K0π+π−, Λπ+, Λπ+π−π+, and Ξ−K+π+ relative to that into pK−π+ are measured to be 0.44±0.07±0.05, 0.43±0.12±0.04, 0.18±0.03±0.03, 0.65±0.11±0.12, and 0.15±0.04±0.03, respectively.

The Fraternal Conceit: Individualist Versus Collectivist Ideas Of Community, Chandran Kukathas Jan 1991

The Fraternal Conceit: Individualist Versus Collectivist Ideas Of Community, Chandran Kukathas

Research Collection School of Social Sciences

In the modern world countless minorities press separate claims for recognition by their fellow countrymen, by their states and, in some cases, by the world. Many of these groups, such as the Australian Aborigines and New Zealand Maoris, describe themselves as indigenous peoples, while others identify themselves simply as ethnic or cultural minorities with legitimate grievances. The various demands made by such groups leave us in no doubt that there is a political problem. But there is also an important philosophical question to be addressed: a question about the terms of civil association. The modern world has seen two great …

A Graphical Knowledge Level Approach For User-Database Interaction, K. Tan, H. Chan, Keng Siau Nov 1990

A Graphical Knowledge Level Approach For User-Database Interaction, K. Tan, H. Chan, Keng Siau

Research Collection School Of Computing and Information Systems

The authors propose a novel user interface, the Graphical Knowledge Level interface, for user-database interaction. This interface addresses two of the current research problems: the semantic inadequacy of the relational model and the logical data dependence of the relational languages. The interface is more user-friendly than the SOL interface and the Universal Relation interface, as it employs the graphical approach. The semantic inadequacy problem is alleviated by using an enhanced entity-relationship model. This data model includes abstraction concepts such as aggregation, generalization, and categorization. A formal, high-level Graphical Knowledge Level Query Language, GKQL, which provides for both logical and physical …

The Hong Kong Jury: A Microcosm Of Society?, Peter Duff, Mark Findlay, Carla Howarth Oct 1990

The Hong Kong Jury: A Microcosm Of Society?, Peter Duff, Mark Findlay, Carla Howarth

Research Collection Yong Pung How School Of Law

The claim that the jury is a randomly chosen and representative sample of community is an important part of the ideology which currently underpins the institution. Supporters of the jury argue that both its impartiality and its independence from the State are bolstered by the fact that it represents a randomly selected cross-section of the populace. In most common law jurisdictions where the jury operates, various steps have been taken over recent years in order preserve and strengthen the perception of the jury as a "microcosm of democratic society". For example, in England the property qualification for jurors was removed …

Geography And Religion: Trends And Prospects, Lily Kong Sep 1990

Geography And Religion: Trends And Prospects, Lily Kong

Research Collection School of Social Sciences

That geography and religion can and do meet to form a valuable focus of inquiry has not always been immediately apparent. While the study of religions has engaged the attention of a large and ever-widening circle of scholars, research has tended to proceed under the varied rubrics of sociology, anthropology, philosophy, history, and certainly, theology. Classics that have had significant impact on the development of 'religious thought' have emerged from the pens of scholars professing several diverse disciplines. For instance, Weber (1904-1905), Durkheim (1976), Otto (1950), and Eliade (1959) represent but a sample of the multifarious writings that have shaped …

How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer Jul 1990

How To Arrive At Computer Integrated Manufacturing: A 3-Year Survey, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

The large majority of modern production companies have at their disposal a multitude of computer systems. The immediate challenge for these companies consists of integrating these computer systems and databases. How will one arrive at this integration? On the basis of a questionnaire administered in 1985, 1986 and 1987 among a group of large European manufacturers, one comes to the conclusion that this integration is one of the immediate priorities for this group of companies. They do not intend to implement turnkey systems. but instead will integrate the different databases and computer systems gradually. One can see emerging islands of …

Lasting Improvements In Manufacturing Performance: In Search Of A New Theory, Kasra Ferdows, Arnoud De Meyer Apr 1990

Lasting Improvements In Manufacturing Performance: In Search Of A New Theory, Kasra Ferdows, Arnoud De Meyer

Research Collection Lee Kong Chian School Of Business

Is there a way to avoid trading off one capability for another in manufacturing? The prevailing wisdom says no. But some manufacturers seem to have been able to defy that: compared to their competitors, they have better quality, are more dependable, respond faster to changing market conditions, and in spite of all that, achieve lower costs. How can this be explained? Our aim here is to provide an explanation. We contend that the nature of the trade-offs among manufacturing capabilities is more complex than has been assumed. Depending on the approach taken for developing each capability, the nature of the …

Determination Of Adopter Categories By Using Innovation Diffusion Models, Vijay Mahajan, Eitan Muller, Rajendra Kumar Srivastava Feb 1990

Determination Of Adopter Categories By Using Innovation Diffusion Models, Vijay Mahajan, Eitan Muller, Rajendra Kumar Srivastava

Research Collection Lee Kong Chian School Of Business

Using the analytical logic underlying the classical adopter categorization approach proposed by Rogers, the authors suggest that adopter categories for a product innovation can also be developed by using their well-established diffusion models such as the Bass model. With data on 11 consumer durable products, they compare adopter categories generated by the classical approach and the Bass diffusion model, respectively. An application examining the diffusion of personal computers is documented to illustrate the usefulness of the adopter categorization based on the Bass diffusion model in studying differences among adopter categories.

Reception Of English Law In Singapore: Problems And Proposed Solutions, Andrew B.L. Phang Jan 1990

Reception Of English Law In Singapore: Problems And Proposed Solutions, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

The problems pertaining to the reception of English law in Singapore are both numerous and complex. The academic literature generated in the local sphere alone is relatively large. It must, however, be conceded that, from apractical point of view, there has been very little interest or at least discussion. One cannot, of course, be sure about this observation, save for the very strong indication that takes the form of the overwhelming lack of litigation in the area, thus rendering it merely (so it appears) an academic monopoly. It should, however, be pointed out that this rather phlegmatic approach in practice …

A Commentary On Professor Fisher’S Thesis: Ideology, Religion, Private Property And The Supreme Court 1987-88, Howard Hunter Jan 1990

A Commentary On Professor Fisher’S Thesis: Ideology, Religion, Private Property And The Supreme Court 1987-88, Howard Hunter

Research Collection Yong Pung How School Of Law

The most important lessons to be learned from Professor Fisher's paper are that the ideologies central to American law have roots in religious thought and that the influence of ideologies can be found throughout American law, perhaps most especially in judicial decisions. To these lessons we can add a third: the ideologies embodied in judicial decisions concerning private property in the period from the American Revolution to the Civil War are still with us. Three recent decisions of the United States Supreme Court' illustrate the continuing importance of the constitutional and ideological protection of private property, while offering an interesting …

Trellis-Coded Multidimensional Phase Modulation, S. S. Pietrobon, Robert H. Deng Jan 1990

Trellis-Coded Multidimensional Phase Modulation, S. S. Pietrobon, Robert H. Deng

Research Collection School Of Computing and Information Systems

A 2L-dimensional multiple phase-shift keyed (L×MPSK) signal set is obtained by forming the Cartesian product of L two-dimensional MPSK signal sets. A systematic approach to partitioning L×MPSK signal sets that is based on block coding is used. An encoder system approach is developed. It incorporates the design of a differential precoder, a systematic convolutional encoder, and a signal set mapper. Trellis-coded L×4PSK, L×8PSK, and L×16PSK modulation schemes are found for 1⩽L⩽4 and a variety of code rates and decoder complexities, many of which are fully transparent to discrete phase rotations of the signal set. The new codes achieve asymptotic coding …

Jurisprudential Oaks From Mythical Acorns: The Hart‐Dworkin Debate Revisited, Andrew B.L. Phang Jan 1990

Jurisprudential Oaks From Mythical Acorns: The Hart‐Dworkin Debate Revisited, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

This article attempts to demonstrate, via the famous Hart-Dworkin debate on the nature and functions of judicial discretion, that substantial jurisprudential disputes as well as theories can, and do, arise from misconceived critiques, whether intended or otherwise. It also seeks to show that, whilst Dworkin's initial critique of Hart was misconceived, his theory of adjudication that arose as a result of responses to his initial views is a positive contribution to learning, although I argue that Dworkin's views are not, in the final analysis, sufficiently persuasive to constitute a radical departure from Hart's own views.

Whither Economic Duress? Reflections On Two Recent Cases, Andrew B.L. Phang Jan 1990

Whither Economic Duress? Reflections On Two Recent Cases, Andrew B.L. Phang

Research Collection Yong Pung How School Of Law

From its rather tentative and extremely recent beginnings, I the law relating to economic duress has developed at a relatively rapid pace during the last decade or so. We have had a series of decisions from various courts and jurisdictions* which, collectively at least, affirm the existence of the doctrine in English law. The pronouncements at the highest levels, however, have not purported to be definitive, and, as we shall see, have certainly not aided in a clarification and systematization of the doctrine of economic duress. The two recent decisions, which are the subject of the present comment, have merely …

Icac And The Community, Mark Findlay Nov 1989

Icac And The Community, Mark Findlay

Research Collection Yong Pung How School Of Law

Recently the language of 'community' has been widely used in the official discourse of criminal justice administration in Australia, in an obvious effort to legitimate new developments away from more traditional crime control. Commentators are now asking, why all this 'community speak' about policing, mediation, and corrections? As regards the 'community' perspective of anti-corruption initiatives, it is an attempt to transfer to the new institutions and processes some of the more positive implications which are assumed to flow from community allegiance.
