Sample-Adaptive Coding Scheme (Sacs): A Structurally Constrained Vector Quantizer, Dong Sik Kim, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In this paper, we propose a novel feed-forward adaptive coding scheme called SACS (sample adaptive coding scheme) for the lossy compression of a discrete-time memoryless stationary source. SACS is based on a concept of adaptive quantization to the varying samples of the source and is very different from traditional adaptation techniques for non-stationary sources. SACS quantizes each solirce sample using a sequence of quantizers. Even when using scalar quantization in SACS, we can ach.ieve performance comparablse to vector quantization (with the complexity still of the order of scalar quantization). We also show tihat important lattice based vector quantizers can be …

Measuring The Deterrent Effect Of Punitive Damages, Theodore Eisenberg

Cornell Law Faculty Publications

Professor Viscusi's article differs from the dominant mode of law and economics scholarship on punitive damages. The usual punitive damages article contains purely theoretical considerations about when punitive damages are appropriate and about their optimal level; no effort is made to ascertain whether the existing pattern of punitive awards corresponds with the theory. This is part of a larger problem: the dearth of empirical evidence in law and economics scholarship. Viscusi, on the other hand, provides empirical tests of whether punitive damages accomplish their goals, and he makes creative use of publicly available data sources. For the goal of his …

Analysis Of Multiphoton Ionization Of Metal Atoms In The Saturation Regime Using Subpicosecond Krf Laser Pulses, B. Witzel, Cornelis J. Uiterwaal, H. Schröder, D. Charalambidis, K.-L. Kompa

C.J.G.J. Uiterwaal Publications

Singly and multiply charged ion yield curves are reported for resonant and nonresonant two photon- ionization processes for a collection of 31 metal atoms. The atoms are created by sputtering from a solid target using an Ar-ion gun. Single and multiple ionization of these atoms is performed using linearly polarized 248.6-nm (KrF) laser pulses with a full width at half maximum duration of 500 fs, employing intensities between 10⁹ and 10¹² W cm^-2. A four-grid high-resolution reflecting time-of-flight spectrometer is used for ion detection. This advanced spectrometer has a well-defined and small source volume, enabling absolute …

Radiative Decay Modes Of The D0 Meson, D. M. Asner, Kenneth A. Bloom, Cleo Collaboration

Kenneth Bloom Publications

In this paper we describe a search for four radiative decay modes of the D⁰ meson: D⁰ → φγ, D⁰ → ωγ, D⁰ → K^-*γ, and D⁰ → ρ⁰γ . We obtain 90% C.L. upper limits on the branching ratios of these modes of 1.9 X 10^-4, 2.4 X 10^-4, 7.6 X 10^-4, and 2.4 X 10^-4, respectively.

Ionization Dynamics In Fast Ion-Atom Collisions. I. Energy And Angular Distributions Of Low-Energy Electrons Emitted In Ionization Of He By Bare Carbon Ions, Lokesh C. Tribedi, P. Richard, Y. D. Wang, C. D. Lin, L. Gulyas, M. Eugene Rudd

M. Eugene Rudd Publications

We have studied the two-center effect (TCE) in ion-atom ionization by measuring the energy and angular distributions of the double-differential cross sections (DDCSs) (d²σ/dεdΩ) of the low-energy electrons emitted in a collision of He atoms with 2.5 MeV/nucleon C⁶⁺ ions. The electrons with energies between 0.1 and 300 eV were detected for 13 different emission angles between 15° and 160°. From the measured DDCSs we have deduced the single differential cross sections such as dσ/dΩ and dσ/dε and the total cross section. The data have been …

Searches For The Neutral Higgs Bosons Of The Mssm In E+E- Collisions At Centre-Of-Mass Energies Of 181-184 Gev, Barate, R.; Et Al., M. Thulasidas

Research Collection School Of Computing and Information Systems

The data collected by ALEPH at LEP at centre-of-mass energies ranging from 181 to 184 GeV, corresponding to an integrated luminosity of 57 pb−1, are analysed to search for pair-produced neutral Higgs bosons h and A, in the bb̄bb̄ and τ+τ−bb̄ final states. Two events are found in the data with 2.5 expected from standard model processes. When combined with the lower energy data collected by ALEPH and with earlier reported searches for associated hZ production, these analyses are interpreted in the context of the minimal supersymmetric extension of the standard model (MSSM). For standard choices of MSSM parameter sets, …

Information Coupling In Web Databases, Sourav S. Bhowmick, Wee-Keong Ng, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Web information coupling refers to an association of topically related web documents. This coupling is initiated explicitly by a user in a web warehouse specially designed for web information. Web information coupling provides the means to derive additional, useful information from the WWW. In this paper, we discuss and show how two web operators, i.e., global web coupling and local web coupling, are used to associate related web information from the WWW and also from multiple web tables in a web warehouse. This paper discusses various issues in web coupling such as coupling semantics, coupling-compability, and coupling evaluation.

High-Resolution Electron Time-Of-Flight Apparatus For The Soft-X-Ray Region, Oliver Hemmers, S. B. Whitfield, P. Glans, H. Wang, Dennis W. Lindle, R. Wehlitz, I. A. Sellin

Environmental Studies Faculty Publications

A gas-phase time-of-flight (TOF) apparatus, capable of supporting as many as six electron-TOF analyzers viewing the same interaction region, has been developed to measure energy- and angle-resolved electrons with kinetic energies up to 5 keV. Each analyzer includes a newly designed lens system that can retard electrons to about 2% of their initial kinetic energy without significant loss of transmission; the analyzers can thus achieve a resolving power (E/ΔE) greater than 10⁴ over a wide kinetic-energy range. Such high resolving power is comparable to the photon energy resolution of state-of-the-art synchrotron–radiation beamlines in the soft …

Photofragmentation Of Third-Row Hydrides Following Photoexcitation At Deep-Core Levels, D. Hansen, M. E. Arrasate, J. Cotter, G. R. Fisher, Oliver Hemmers, K. T. Leung, Jon C. Levin, R. Martin, Paul Neill, Rupert C. Perera, I. A. Sellin, Marc Simon, Y. Uehara, B. Vanderford, S. B. Whitfield, Dennis W. Lindle

Environmental Studies Faculty Publications

The relaxation dynamics of HCl, DCl, H₂S, and D₂S following photoexcitation in the vicinities of the Cl and S K-shell thresholds (∼2.8keV for Cl, ∼2.5 keV for S) were studied by means of ion time-of-flight mass spectroscopy. In all cases, the onset of pre-edge core-shell photoionization precedes the formation on resonance of a significant amount of neutral hydrogen as well as postcollision-interaction effects above threshold. Examination of the width of the H⁺ peak in spectra taken with the analyzer parallel and perpendicular to the polarization vector of the incident light indicates that on resonance, the …

Why There Is No Defense Of Punitive Damages, W. Kip Viscusi

Vanderbilt Law School Faculty Publications

This paper is a response to the comments by David Luban and Theodore Eisenberg on my article on punitive damages to be published in the Georgetown Law Journal (1998) and entitled "The Social Costs of Punitive Damages against Corporations in Environmental and Safety Tort." Neither of these authors presents any evidence indicating that there is a determent effect of punitive damages. They suggest, however, that there could be retribution objectives or other rationales for punitive damages. In addition, they claim that punitive damages are predictable and that cognitive biases may not tilt juries against corporations. This paper reviews these diverse …

The Legal Implications Of Psychology: Human Behavior, Behavioral Economics, And The Law Symposium: The Legal Implications Of Psychology Human Behavior, Behavioral Economics, And The Law, Stephen D. Hurd

Vanderbilt Law Review

Nearly all interesting legal issues require accurate predictions about human behavior to be resolved satisfactorily. Judges, policy- makers, and academics invoke mental models of individual and social behavior whenever they estimate the desirability of alternative rules, policies, or procedures. Contemporary legal scholarship has come to recognize that if these predictions are naive and intuitive, without any strong empirical grounding, they are susceptible to error and ideological bias. Something more rigorous is thus expected when normative claims are advanced, and the place of the social sciences has expanded in legal discourse to satisfy this expectation.'

Tga–Fti.R. Investigation Of The Thermal Degradation Of Nafion® And Nafion®/[Silicon Oxide]-Based Nanocomposites, Q. Deng, Charles Wilkie, R. B. Moore, Kenneth A. Mauritz

Chemistry Faculty Research and Publications

The integrated TGA–FTi.r. technique probed the thermal degradation of: (1) a Nafion®–H⁺ membrane; (2) this membrane as modified by incorporation of a SiO_2[1-x/4] (OH)_x phase via in situ sol–gel reactions for tetraethoxysilane; and (3) this modified membrane as further modified, organically, via post-reaction with diethoxydimethylsilane. Gravimetric loss is multistep for (1) and (2), but occurs in a single step for (3) which has the greatest thermal degradative stability. The considerable inhibition of SO₂ evolution for (2) and (3) is rationalized in terms of side-chains that are immobilized within silicon oxide cages …

Portfolio Assessment In Vocational Education: The Assessor's View, Zita M. Wagner

Australian Journal of Teacher Education

Portfolio assessment has been traditionally used in art, design, music, writing and dance programs. However in recent years the use of portfolio assessment in vocational education has expanded to include many different subject areas such as economics, business, nursing, human resources, mathematics and engineering. As an assessment tool the portfolio has much to offer in terms of involving students in the assessment process and in documenting their achievements. From the assessor's point of view, the use of portfolios for assessment raises issues of reliability, the time consuming nature of assessment, objectivity and authenticity of the work. In this paper twentyfour …

Managing New Product Definition In Highly Dynamic Environments, Shantanu Bhattacharya, Viswanathan Krishnan, Vijay Mahajan

Research Collection Lee Kong Chian School Of Business

In highly dynamic environments, characterized by changing customer preferences and uncertainty about competitive products, managing the development of a new product is a complex managerial task. The traditional practice, recommended in the literature, of reaching a sharp definition early in the new product development (NPD) process may not be optimal, desirable or even feasible in such dynamic situations. Under high uncertainty, forcing early finalization of specifications may result in a firm getting locked into an incorrect definition. Based on our study of NPD in the high technology industry, we present a model of an approach called real-time definition, in which …
