Editorial: Three types of interaction

by Michael G. Moore - The American Journal of Distance Education , 1992
"... Many of the greatest problems of communicating about concepts, and, therefore, practice in distance education arise from our use of crude hypothetical constructs-terms like distance, independence, and interaction, which are used in very imprecise and general ways, each having acquired a multiplicity ..."

and instructor, but by too few users in the more technical and specific meanings as discussed, for example, by Saba (1988), Keegan (1988), Shale (1988), or Moore (1984). Interaction is another important term that carries so many meanings as to be almost useless unless specific submeanings can be defined

DESIGN AND PERFORMANCE OF THE NEW SARTORIUS 1 KG VACUUM MASS COMPARATOR AT PTB

by M. Borys, T. Fehling, T. Fröhlich, D. Heydenbluth, M. Mecke, R. Schwartz
"... Abstract: A new type of a 1 kg vacuum mass comparator was developed in a collaboration between the Sartorius AG, the Technical University Ilmenau and the BIPM. The first comparator of this new type was installed at PTB. In this paper the set-up of the system and the local conditions are described. F ..."

NetSolve: A Network Server for Solving Computational Science Problems

by Henri Casanova, Jack Dongarra - The International Journal of Supercomputer Applications and High Performance Computing , 1995
"... This paper presents a new system, called NetSolve, that allows users to access computational resources, such as hardware and software, distributed across the network. This project has been motivated by the need for an easy-to-use, efficient mechanism for using computational resources remotely. Ease ..."

Pseudorandom generators for space-bounded computation

by Noam Nisan - Combinatorica , 1992
"... Pseudorandom generators are constructed which convert O(SlogR) truly random bits to R bits that appear random to any algorithm that runs in SPACE(S). In particular, any randomized polynomial time algorithm that runs in space S can be simulated using only O(Slogn) random bits. An application of these ..."

of these generators is an explicit construction of universal traversal sequences (for arbitrary graphs) of length n O(l~ The generators constructed are technically stronger than just appearing random to spacebounded machines, and have several other applications. In particular, applications are given for "

Continuous Time-Varying Scalar Systems - a Behavioural Approach

by A. Ilchmann, Y. Kuang, M. Kuijper, C. Zhang , 2000
"... We introduce a behavioural approach to linear time-varying systems p( d dt )w 1 = q( d dt )w 2 , where p(D); q(D) belong to M[D], i.e. the skew polynomial ring with real meromorphic coefficients M, indeterminate D, and multiplication rule Df = fD+ f . Willem's behavioural approach to tim ..."

Trapdoors for Hard Lattices and New Cryptographic Constructions

by Craig Gentry, Chris Peikert, Vinod Vaikuntanathan , 2007
"... We show how to construct a variety of “trapdoor ” cryptographic tools assuming the worstcase hardness of standard lattice problems (such as approximating the shortest nonzero vector to within small factors). The applications include trapdoor functions with preimage sampling, simple and efficient “ha ..."

“hash-and-sign ” digital signature schemes, universally composable oblivious transfer, and identity-based encryption. A core technical component of our constructions is an efficient algorithm that, given a basis of an arbitrary lattice, samples lattice points from a Gaussian-like probability
