CURE: An Efficient Clustering Algorithm for Large Data sets

by Sudipto Guha, Rajeev Rastogi, Kyuseok Shim - Published in the Proceedings of the ACM SIGMOD Conference , 1998
"... Clustering, in data mining, is useful for discovering groups and identifying interesting distributions in the underlying data. Traditional clustering algorithms either favor clusters with spherical shapes and similar sizes, or are very fragile in the presence of outliers. We propose a new clustering ..."

and then shrinking them toward the center of the cluster by a specified fraction. Having more than one representative point per cluster allows CURE to adjust well to the geometry of non-spherical shapes and the shrinking helps to dampen the effects of outliers. To handle large databases, CURE employs a combination

Priority Encoding Transmission

by Andres Albanese, Johannes Blömer, Jeff Edmonds, Michael Luby, Madhu Sudan - IEEE Transactions on Information Theory , 1994
"... We introduce a new method, called Priority Encoding Transmission, for sending messages over lossy packet-based networks. When a message is to be transmitted, the user specifies a priority value for each part of the message. Based on the priorities, the system encodes the message into packets for tra ..."

A model of reserves, bank runs, and deposit insurance

by John Bryant - Journal of Banking and Finance , 1980
"... A model is presented in which demand deposits backed by fractional currency reserves and public insurance can be beneficial. The model uses Samuelson's pure consumption-loans model. The case for demand deposits, reserves, and deposit insurance rests on costs of iUiquidity and incomplete informa ..."

Permission accounting in separation logic

by Richard Bornat, Cristiano Calcagno, Matthew Parkinson - In POPL , 2005
"... A lightweight logical approach to race-free sharing of heap storage between concurrent threads is described, based on the notion of permission to access. Transfer of permission between threads, subdivision and combination of permission is discussed. The roots of the approach are in Boyland’s [3] dem ..."

We add the notion of counting permission, which mirrors the programming technique called permission counting. Both fractional and counting permissions permit passivity, the specification that a

Issues in the Estimation of Mis-Specified Models of Fractionally Integrated Processes

by K. Nadarajah, Gael M. Martin, D. S. Poskitt , 2014
"... literature presupposes that the structure of the TDGP is known apart from the values of a finite number of parameters that are to be estimated. Recognition that the true structure can only ever be approximated by the model being fitted has given rise to two responses: (i) the development of semi-par ..."

Specifically, Yajima investigates the asymptotic properties of the estimators of the parameters in an autoregressive moving average (ARMA) model under a long memory fractional noise TDGP; whilst Chen and Deo focus on the estimation of the parameters in an incorrectly specified fractionally integrated model

Specifying Rewrite Strategies for Interactive Exercises

by Bastiaan Heeren, Johan Jeuring, Alex Gerdes
"... Abstract. Strategies specify how a wide range of exercises can be solved incrementally, such as bringing a logic proposition to disjunctive normal form, reducing a matrix, or calculating with fractions. In this paper we introduce a language for specifying strategies for solving exercises. This langu ..."

An Energy Efficient MAC Protocol for Wireless LANs

by Eun-sun Jung, Nitin H. Vaidya - IEEE INFOCOM , 2002
"... This paper presents an optimization of the power saving mechanism in the Distributed Coordination Function (DCF) in IEEE 802.11 standard. In the IEEE 802.11 power saving mode specified for DCF, time is divided into so-called beacon intervals. At the start of each beacon interval, each node in the po ..."

Specifying high-performance coatings for concrete

by Thomas E. Remmele - Construction Specifier

Monotonous gray concrete can be turned into colors appealing to the eye, adding warmth and scale to an otherwise unattractive facade. Texture can be added to give liveliness to an ot ..."

Besides adding color, texture, and form, high-performance acrylic-textured coating systems provide a layer of protection against concrete deterioration
