Non-Uniform Random Variate Generation

by Luc Devroye , 1986
"... This is a survey of the main methods in non-uniform random variate generation, and highlights recent research on the subject. Classical paradigms such as inversion, rejection, guide tables, and transformations are reviewed. We provide information on the expected time complexity of various algorith ..."

Taming the Underlying Challenges of Reliable Multihop Routing in Sensor Networks

by Alec Woo, Terence Tong, David Culler - In SenSys , 2003
"... The dynamic and lossy nature of wireless communication poses major challenges to reliable, self-organizing multihop networks. These non-ideal characteristics are more problematic with the primitive, low-power radio transceivers found in sensor networks, and raise new issues that routing protocols mu ..."

-node, in-depth empirical experiments. The most effective solution uses a simple time averaged EWMA estimator, frequency based table management, and cost-based routing.

Efficient implementation of a BDD package

by Karl S. Brace, Richard L. Rudell, Randal E. Bryant - In Proceedings of the 27th ACM/IEEE conference on Design autamation , 1991
"... Efficient manipulation of Boolean functions is an important component of many computer-aided design tasks. This paper describes a package for manipulating Boolean functions based on the reduced, ordered, binary decision diagram (ROBDD) representation. The package is based on an efficient implementat ..."

implementation of the if-then-else (ITE) operator. A hash table is used to maintain a strong carwnical form in the ROBDD, and memory use is improved by merging the hash table and the ROBDD into a hybrid data structure. A memory funcfion for the recursive ITE algorithm is implemented using a hash-based cache

Monopolistic competition and optimum product diversity. The American Economic Review,

by Avinash K Dixit , Joseph E Stiglitz , Harold Hotelling , Nicholas Stern , Kelvin Lancaster , Stiglitz , 1977
"... The basic issue concerning production in welfare economics is whether a market solution will yield the socially optimum kinds and quantities of commodities. It is well known that problems can arise for three broad reasons: distributive justice; external effects; and scale economies. This paper is c ..."

constant marginal cost. Modeling the desirability of variety has been thought to be difficult, and several indirect approaches have been adopted. The Hotelling spatial model, Lancaster's product characteristics approach, and the mean-variance portfolio selection model have all been put to use.3

An almost ideal demand system.

by Angus Deaton , John Muellbauer - American Economic Review, , 1980
"... Ever since Richard Stone (1954) first estimated a system of demand equations derived explicitly from consumer theory, there has been a continuing search for alternative specifications and functional forms. Many models have been proposed, but perhaps the most important in current use, apart from the ..."

The Nature and Growth of Vertical Specialization in World Trade

by David Hummels - Journal of International Economics
"... Abstract: Dramatic changes are occurring in the nature of international trade. Production processes increasingly involve a sequential, vertical trading chain stretching across many countries, with each country specializing in particular stages of a good’s production sequence. We document a key aspe ..."

aspect of these vertical linkages – the use of imported inputs in producing goods that are exported – which we call vertical specialization. Using input-output tables from the OECD and emerging market countries we estimate that vertical specialization accounts for up to 30 % of world exports, and has

Why don’t issuers get upset about leaving money on the table in IPOs?

by Tim Loughran , Jay R Ritter , Chi Chen , Kent Daniel , Harry Deangelo , Craig Dunbar , Bruce Foerster , Jason Karceski , Robert Korajczyk , Alexander Ljungqvist , M Nimalendran , Michael Ryngaert , Hersh Shefrin , William Wilhelm , Kent Womack , Li-Anne - Review of Financial Studies , 2002
"... Abstract One of the puzzles regarding initial public offerings (IPOs) is that issuers rarely get upset about leaving substantial amounts of money on the table, defined as the number of shares sold times the difference between the first-day closing market price and the offer price. The average IPO l ..."

leaves $9.1 million on the table. This number is approximately twice as large as the fees paid to investment bankers, and represents a substantial indirect cost to the issuing firm. We present a prospect theory model that focuses on the covariance of the money left on the table and wealth changes. Our

AntNet: Distributed stigmergetic control for communications networks

by Gianni Di Caro, Marco Dorigo - JOURNAL OF ARTIFICIAL INTELLIGENCE RESEARCH , 1998
"... This paper introduces AntNet, a novel approach to the adaptive learning of routing tables in communications networks. AntNet is a distributed, mobile agents based Monte Carlo system that was inspired by recent work on the ant colony metaphor for solving optimization problems. AntNet's agents co ..."

Removing The Costs Of Indirection in Flash-based SSDs with Nameless Writes

by Andrea C. Arpaci-dusseau, Remzi H. Arpaci-dusseau, Vijayan Prabhakaran
"... We present nameless writes, a new interface that obviates the need for indirection in modern solid-state storage devices (SSDs). Nameless writes allow the device to pick the location of a write and only then inform the client above of the decision. Doing so keeps control of block allocation decision ..."
