Motivation through the Design of Work: Test of a Theory. Organizational Behavior and Human Performance,

by ] Richard Hackman , Grec R Oldham , 1976
"... A model is proposed that specifies the conditions under which individuals will become internally motivated to perform effectively on their jobs. The model focuses on the interaction among three classes of variables: (a) the psychological states of employees that must be present for internally motiv ..."

of the work 254 HACKMAN AND OLDHAM setting and the device of the autonomous work group. Absent from the approach, for example, are explicit means for diagnosing a work system prior to change (to ascertain what "should" be changed, and how), or for evaluating in systematic terms the outcomes

A Rate-Adaptive MAC Protocol for Multi-Hop Wireless Networks

by Gavin Holland, Nitin H. Vaidya, Paramvir Bahl , 2001
"... Wireless local area networks (W-LANs) have become increasingly popular due to the recent availability of affordable devices that are capable of communicating at high data rates. These high rates are possible, in part, through new modulation schemes that are optimized for the channel conditions bring ..."

. Users are given the option to either select an operational data rate manually or to let the device automatically choose the appropriate modulation scheme (data rate) to match the prevailing conditions. Automatic rate selection protocols have been studied for cellular networks but there have been

Interactive Control of Avatars Animated with Human Motion Data

by Jehee Lee, Jinxiang Chai, Paul S. A. Reitsma, Jessica K. Hodgins, Nancy S. Pollard , 2002
"... Real-time control of three-dimensional avatars is an important problem in the context of computer games and virtual environments. Avatar animation and control is difficult, however, because a large repertoire of avatar behaviors must be made available, and the user must be able to select from this s ..."

this set of behaviors, possibly with a low-dimensional input device. One appealing approach to obtaining a rich set of avatar behaviors is to collect an extended, unlabeled sequence of motion data appropriate to the application. In this paper, we show that such a motion database can be preprocessed

Sampling signals with finite rate of innovation

by Martin Vetterli, Pina Marziliano, Thierry Blu - IEEE Transactions on Signal Processing , 2002
"... Abstract—Consider classes of signals that have a finite number of degrees of freedom per unit of time and call this number the rate of innovation. Examples of signals with a finite rate of innovation include streams of Diracs (e.g., the Poisson process), nonuniform splines, and piecewise polynomials ..."

polynomials. Even though these signals are not bandlimited, we show that they can be sampled uniformly at (or above) the rate of innovation using an appropriate kernel and then be perfectly reconstructed. Thus, we prove sampling theorems for classes of signals and kernels that generalize the classic

Terabit burst switching

by Jonathan S. Turner - J. of High Speed Networks , 1999
"... This report summarizes the results of an architectural study on Terabit Burst Switching. The purpose of this study was to explore alternative architectures for very high performance switching for data communication, using a combination of optical and electronic technologies. We explore two alternati ..."

rests on the development of inexpensive optical wavelength conversion devices. Appropriate devices could be available in ve to ten years.

Direct cortical control of 3d neuroprosthetic devices

by Dawn M. Taylor, Stephen I. Helms Tillery, Andrew B. Schwartz - Science , 2002
"... Three-dimensional (3D) movement of neuroprosthetic devices can be con-trolled by the activity of cortical neurons when appropriate algorithms are used to decode intended movement in real time. Previous studies assumed that neurons maintain Þxed tuning properties, and the studies used subjects who we ..."

The Web Service Modeling Framework WSMF

by D. Fensel, C. Bussler, Y. Ding, B. Omelayenko - ELECTRONIC COMMERCE RESEARCH AND APPLICATIONS , 2001
"... Web Services will transform the web from a collection of information into a distributed device of computation. In order to employ their full potential, appropriate description means for web services need to be developed. For this purpose we define a fullfledged Web Service Modeling Framework (WSMF ..."

A Forward-Secure Public-Key Encryption Scheme

by Ran Canetti, Shai Halevi, Jonathan Katz , 2003
"... Cryptographic computations are often carried out on insecure devices for which the threat of key exposure represents a serious and realistic concern. In an e#ort to mitigate the damage caused by exposure of secret data (e.g., keys) stored on such devices, the paradigm of forward security was int ..."

Integrality and Separability of Input Devices

by Robert J. K. Jacob, Linda E. Sibert, Daniel C. Mcfarlane, M. Preston Mullen - ACM Transactions on Computer-Human Interaction , 1994
"... Current input device taxonomies and other frameworks typically emphasize the mechanical structure of input devices. We suggest that selecting an appropriate input device for an interactive task requires looking beyond the physical structure of devices to the deeper perceptual structure of the task, ..."
