Scalable Implementation of Synchronization Primitives on Broadcast Rings
, 1993
"... Synchronization is an important aspect of parallel program design. By definition synchronization is an aspect of a program where multiple processors participate. Thus it is important to design and implement hardware primitives that scale well with the size of the parallel machine, both in terms of s ..."

of space and time requirements. The focus of this research is to propose implementation for some wellknown synchronization primitives in a broadcast ring network. The key aspects of the implementation are to make local decisions to determine the outcome of the synchronization operations; and to keep
Sequential data assimilation with a nonlinear quasigeostrophic model using Monte Carlo methods to forecast error statistics
 J. Geophys. Res
, 1994
"... . A new sequential data assimilation method is discussed. It is based on forecasting the error statistics using Monte Carlo methods, a better alternative than solving the traditional and computationally extremely demanding approximate error covariance equation used in the extended Kalman filter. The ..."

. The unbounded error growth found in the extended Kalman filter, which is caused by an overly simplified closure in the error covariance equation, is completely eliminated. Open boundaries can be handled as long as the ocean model is well posed. Wellknown numerical instabilities associated with the error
Factoring polynomials with rational coefficients
 MATH. ANN
, 1982
"... In this paper we present a polynomialtime algorithm to solve the following problem: given a nonzero polynomial fe Q[X] in one variable with rational coefficients, find the decomposition of f into irreducible factors in Q[X]. It is well known that this is equivalent to factoring primitive polynomia ..."

The process group approach to reliable distributed computing
 Communications of the ACM
, 1993
"... The difficulty of developing reliable distributed softwme is an impediment to applying distributed computing technology in many settings. Expeti _ with the Isis system suggests that a structured approach based on virtually synchronous _ groups yields systems that are substantially easier to develop, ..."

An Object Calculus for Asynchronous Communication
 Proceedings of the European Conference on ObjectOriented Programming (ECOOP
, 1991
"... This paper presents a formal system based on the notion of objects and asynchronous communication. Built on Milner's work on ßcalculus, the communication primitive of the formal system is purely asynchronous, which makes it unique among various concurrency formalisms. Computationally this resu ..."

A Locked CacheBased Synchronization Protocol for CMP
"... Abstract CMP processors are already replacing complex single core superscalar processor architectures. They offer better performance per watt and area. This is especially true in TLP rich server and web applications. Process / thread synchronization is important since CMP consists of multiple proce ..."

with well known synchronization primitives (LL, SC) using MESI cache coherence protocol. Experiments were performed on the modified MP_Simplesim simulator to implement current proposal. Simulation results show that LCCP outperforms the MESI protocol on the benchmark programs
A Fuzzy Commitment Scheme
 ACM CCS'99
, 1999
"... We combine wellknown techniques from the areas of errorcorrecting codes and cryptography to achieve a new type of cryptographic primitive that we refer to as a fuzzy commitment scheme. Like a conventional cryptographic commitment scheme, our fuzzy commitment scheme is both concealing and binding: i ..."

On the Minimal Synchronism Needed for Distributed Consensus
 Journal of the ACM
, 1987
"... Abstract. Reaching agreement is a primitive of distributed computing. Whereas this poses no problem in an ideal, failurefree environment, it imposes certain constraints on the capabilities of an actual system: A system is viable only if it permits the existence of consensus protocols tolerant to so ..."

A wellknown German psychologist

Schiepek, drew our attention some ten years ago to a tendency within systemic discourse that leads us to quickly assimilate any new idea stemming from the sciences without having first explored in depth the possible benefits of the present position. Schiepek called this attitude a ‘tourism of ideas ’ that reflects the fact that psychotherapy also is obviously subjected to the rules of fashion and market. Not exactly in these terms but similarly critical, Carmel Flaskas ’ book Family Therapy Beyond Postmodernism points to the limitations of either/or positioning as it is encountered when having to decide
