Quantization Index Modulation: A Class of Provably Good Methods for Digital Watermarking and Information Embedding

by Brian Chen, Gregory W. Wornell - IEEE TRANS. ON INFORMATION THEORY , 1999
"... We consider the problem of embedding one signal (e.g., a digital watermark), within another "host" signal to form a third, "composite" signal. The embedding is designed to achieve efficient tradeoffs among the three conflicting goals of maximizing information-embedding rate, mini ..."

Implementing data cubes efficiently

by Venky Harinarayan, Anand Rajaraman, Jeffrey D. Ulman - In SIGMOD , 1996
"... Decision support applications involve complex queries on very large databases. Since response times should be small, query optimization is critical. Users typically view the data as multidimensional data cubes. Each cell of the data cube is a view consisting of an aggregation of interest, like total ..."

to materialize. The greedy algorithm performs within a small constant factor of optimal under a variety of models. We then consider the most common case of the hypercube lattice and examine the choice of materialized views for hypercubes in detail, giving some good tradeoffs between the space used

Specification Analysis of Affine Term Structure Models

by Qiang Dai, Kenneth J. Singleton - JOURNAL OF FINANCE , 2000
"... This paper explores the structural differences and relative goodness-of-fits of affine term structure models (ATSMs55). Within the family of ATSMs there is a tradeoff between flexibility in modeling the conditional correlations and volatilities of the risk factors. This trade-off is formalized by ou ..."

What Can Economists Learn from Happiness Research?

by Bruno S. Frey, Alois Stutzer - FORTHCOMING IN JOURNAL OF ECONOMIC LITERATURE , 2002
"... Happiness is generally considered to be an ultimate goal in life; virtually everybody wants to be happy. The United States Declaration of Independence of 1776 takes it as a self-evident truth that the “pursuit of happiness” is an “unalienable right”, comparable to life and liberty. It follows that e ..."

that economics is – or should be – about individual happiness. In particular, the question is how do economic growth, unemployment and inflation, as well as institutional factors such as good governance, affect individual well-being? In addition to this intrinsic interest, there are three major reasons

The theory and practice of corporate finance: Evidence from the field

by John R. Graham, Campbell R. Harvey - Journal of Financial Economics , 2001
"... We survey 392 CFOs about the cost of capital, capital budgeting, and capital structure. Large firms rely heavily on present value techniques and the capital asset pricing model, while small firms are relatively likely to use the payback criterion. We find that a surprising number of firms use their ..."

their firm risk rather than project risk in evaluating new investments. Firms are concerned about maintaining financial flexibility and a good credit rating when issuing debt, and earnings per share dilution and recent stock price appreciation when issuing equity. We find some support for the pecking

Tellambura A good trade-off performance between the code rate and the PMEPR for OFDM signals using the generalized RudinShapiro polynomials

by Wen Chen, Chintha Tellambura - IEEE International Conference on Communications (ICC , 2005
"... Abstract — Generalized Golay complementary sequences and multiple-shift complementary sequences have recently been in-troduced to encode orthogonal frequency division multiplexing (OFDM) signals, reducing the peak-to-mean envelope power ratio (PMEPR). Certain classes of these complementary sequences ..."
Abstract - Cited by 2 (2 self) - Add to MetaCart
such that the code rate increases linearly with respect to the PMEPR. Therefore, it offers an excellent trade-off performance between the code rate and the PMEPR. I.

Techniques for Addressing Fundamental Privacy and Disruption Tradeoffs in Awareness Support Systems

by Scott E. Hudson, Ian Smith , 1996
"... This paper describes a fundamental dual tradeoff that occurs in systems supporting awareness for distributed work groups, and presents several specific new techniques which illustrate good compromise points within this tradeoff space. This dual tradeoff is between privacy and awareness, and between ..."

The Trade-offs of Multicast Trees and Algorithms

by Liming Wei, Deborah Estrin , 1994
"... Multicast trees can be shared across sources (shared trees) or may be source-specific (shortest path trees). Inspired by recent interests in using shared trees for interdomain multicasting, we investigate the trade-offs among shared tree types and source specific shortest path trees, by comparing pe ..."

The Provision of Public Goods Under Alternative Electoral Incentives

by Alessandro Lizzeri, Nicola Persico , 1999
"... We discuss a fundamental trade-off in the political process that can lead to inefficient provision of public goods: politicians may not offer to provide socially desirable public goods because the benefits of the public good cannot be targeted to voters as easily as pork barrel spending. We study ho ..."
