Fundamental Requirements

by M. J. Cookez
"... The different dry equipment approaches to atomic layer etching (ALEt) are reviewed. The requirements for laboratory equipment are met best by ion beam stimulated desorption of surface species, while production equipment is likely to be close to existing plasma etch tools, but with fast pulse cycling ..."

FUNDAMENTAL REQUIREMENTS FOR PICTURE PRESENTATION

by M. F. Cowlishaw
"... Abstract — "How many bits per picture element does a display need?" For the display resolutions now commonly in use, only 4 bits per picture element (pel) are needed for the display of monochrome images. A total of 8 bits per pel are needed for color images. These conclusions are b ..."

Fundamental Design Issues for the Future Internet

by Scott Shenker - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 1995
"... The Internet has been a startling and dramatic success. However, multimedia applications, with their novel traffic characteristics and service requirements, pose an interesting challenge to the technical foundations of the Internet. In this paper we address some of the fundamental architectural d ..."

Accuracy: The Fundamental Requirement for Voting Systems

by Tim Storer, Russell Lock
"... Abstract—There have been several attempts to develop a comprehensive account of the requirements for voting systems, particularly for public elections. Typically, these approaches identify a number of “high level ” principals which are then refined either into more detailed statements or more formal ..."

Option Pricing: A Simplified Approach

by John C. Cox, Stephen A. Ross, Mark Rubinstein - Journal of Financial Economics , 1979
"... This paper presents a simple discrete-time model for valumg optlons. The fundamental econonuc principles of option pricing by arbitrage methods are particularly clear In this setting. Its development requires only elementary mathematics, yet it contains as a special limiting case the celebrated Blac ..."

Fundamental requirements of personalised elearning development environments

by Declan Dagger Owen Conlan - Proceedings of World Conference on E-Learning in Corporate, Government, Healthcare, and Higher Education 2005 , 2005
"... Although personalised eLearning can offer many tangible benefits to the entire educational process such as teacher and learner empowerment [Conlan et. al. 2004] [Bajraktarevic et. al. 2003], educational community collaboration and tailored eLearning delivered just in time and just for you, several i ..."

. This range of issues can be addressed by identifying and representing the core fundamental requirements of personalised eLearning development environments, personalised eLearning services and the disparate design elements involved with the personalised eLearning development process. This paper will explore

Algorithms for Scalable Synchronization on Shared-Memory Multiprocessors

by John M. Mellor-crummey, Michael L. Scott - ACM Transactions on Computer Systems , 1991
"... Busy-wait techniques are heavily used for mutual exclusion and barrier synchronization in shared-memory parallel programs. Unfortunately, typical implementations of busy-waiting tend to produce large amounts of memory and interconnect contention, introducing performance bottlenecks that become marke ..."

markedly more pronounced as applications scale. We argue that this problem is not fundamental, and that one can in fact construct busy-wait synchronization algorithms that induce no memory or interconnect contention. The key to these algorithms is for every processor to spin on separate locally

RSVP: A New Resource Reservation Protocol

by Lixia Zhang, Stephen Deering, Deborah Estrin, Scott Shenker, et al. , 1993
"... Whe origin of the RSVP protocol can be traced back to 1991, when a team of network researchers, including myself, started playing with a number of packet scheduling algorithms on the DARTNET (DARPA Testbed NETwork), a network testbed made of open source, workstation-based routers. Because scheduling ..."
Abstract - Cited by 1005 (25 self) - Add to MetaCart
scheduling algorithms simply shuffle packet processing orders according to some established rates or priorities for different data flows, to test a scheduling algorithm requires setting up the appropriate control state at each router along the data flow paths. I was challenged to design a set-up protocol

Proposed NIST Standard for Role-Based Access Control

by David F. Ferraiolo, Ravi Sandhu, Serban Gavrila, D. Richard Kuhn, Ramaswamy Chandramouli , 2001
"... In this article we propose a standard for role-based access control (RBAC). Although RBAC models have received broad support as a generalized approach to access control, and are well recognized for their many advantages in performing large-scale authorization management, no single authoritative def ..."

As such, this document does not attempt to standardize RBAC features beyond those that have achieved acceptance in the commercial marketplace and research community, but instead focuses

Axiomatic quantum field theory in curved spacetime

by Stefan Hollands, Robert M. Wald , 2008
"... The usual formulations of quantum field theory in Minkowski spacetime make crucial use of features—such as Poincare invariance and the existence of a preferred vacuum state—that are very special to Minkowski spacetime. In order to generalize the formulation of quantum field theory to arbitrary globa ..."
