RNC: A High-Precision Network Coordinate System
"... Abstract—Network Coordinate System (NCS) has drawn much attention over the past years thanks to the increasing number of large-scale distributed systems that require the distance prediction service for each pair of network hosts. The existing schemes suffer seriously from either low prediction preci ..."

precision or unsatisfactory convergence speed. In this paper, we present a novel distributed network coordinate system based on Robust Principal Component Analysis, RNC, that uses a few local distance measurements to calculate high-precision coordinates without convergence process. To guarantee the non
Selforganized control of bipedal locomotion by neural oscillators in unpredictable environment. Biol. Cybern
, 1991
"... Abstract. A new principle of sensorimotor control of legged locomotion in an unpredictable environment is proposed on the basis of neurophysiological knowledge and a theory of nonlinear dynamics. Stable and flexible locomotion is realized as a global limit cycle generated by a global entrainment bet ..."

between the rhythmic activities of a nervous ystem composed of coupled neural oscil-lators and the rhythmic movements of a musculo-skele-tal system including interaction with its environment. Coordinated movements are generated not by slaving to an explicit representation f the precise trajectories
Algorithms for Arbitrary Precision Floating Point Arithmetic
- Proceedings of the 10th Symposium on Computer Arithmetic
, 1991
"... We present techniques which may be used to perform computations of very high accuracy using only straightforward floating point arithmetic operations of limited precision, and we prove the validity of these techniques under very general hypotheses satisfied by most implementations of floating point ..."

Optical Coordination Sensor for Precision Cooperating Robots
- IN IEEE INT’L. CONF. ON ROBOTICS AND AUTOMATION
, 2000
"... The need for high precision robotic systems has increased in recent years. Examples include automated assembly of complex electro-mechanical products such as disk drives, cameras, and medical devices. In this paper we present an optical sensor which can sense motion with better than 0.15 m resolutio ..."

Visually guided coordination for distributed precision assembly
- In IEEE Int’l. Conf. on Robotics and Automation
, 2000
"... This report documents the integration of machine vision into the minifactory environment. Minifactory is an automated factory system being developed at the Microdynamic Systems Laboratory at Carnegie Mellon University and is aimed toward the assembly of small mechatronic devices. Machine vision can ..."

systems described in this report, two high-precision 2-DOF robotic agents were visually guided to precisely align parts of a sub-assembly. Test results show that open-loop look-and-move alignment of parts took an average of 3.7 iterations and 3.6 seconds while visual servoing alignment took an average
Coordination risk and the price of debt
- MIMEO, LONDON SCHOOL OF ECONOMICS & POLITICAL SCIENCE
, 2001
"... Creditors of a distressed borrower face a coordination problem. Even if the fundamentals are sound, fear of premature foreclosure by others may lead to pre-emptive action, undermining the project. Recognition of this problem lies behind corporate bankruptcy provisions across the world, and it has be ..."

Rattle : a ”velocity” version of the Shake algorithm for molecular dynamics calculations
- J. Comput. Phys
, 1983
"... An algorithm, called RATTLE, for integrating the equations of motion in molecular dynamics calculations for molecular models with internal constraints is presented. The algorithm is similar to SHAKE, which is one of the standard methods for performing such calculations. RATTLE calculates the positio ..."

the configuration of a molecule with internal constraints. RATTLE guarantees that the coordinates and velocities of the atoms in a molecule satisfy the internal constraints at each time step. RATTLE has two advantages over SHAKE. On computers of fixed precision. it is of higher precision than SHAKE. Since it deals
Towards coordinated precision assembly with robot teams
- in International Symposium of Experimental Robotics
, 2014
"... Abstract. We present a system in which a flexible team of robots coor-dinate to assemble large, complex, and diverse structures autonomously. Our system operates across a wide range of spatial scales and tolerances, using a hierarchical perception architecture. For the successful execution of very p ..."

: upon losing track of a feature, our system retracts to using high-field of view systems to re-localize. Additionally, we contribute manipulation skills and tools necessary to assemble large structures with high precision. First, the team of robots coordinate to transport large assembly parts which
Precise Signals and Multiple Equilibria in Coordination Games: an Illustration
, 2003
"... Abstract: There is a growing literature using the global game approach to study coordination games. Several papers show a unique equilibrium as long as signals are not too noisy. In this paper, we provide an example in the context of currency attack in which multiple equilibria exist no matter how s ..."
