In this paper we describe a systematic approach to derive a bilingual lexicon automatically from paral lel corpora Following this approach a lexicon was derived from the English and Dutch version of the Agenda corpus With the lexicon and a part of the corpus that was not used to derive the lexicon a bilingual retrieval environment was build Recall and precision of monolingual Dutch retrieval wa...

Space mission with multiple spacecraft formation is an important means to space operation. A new relative navigation algorithm based on stereo vision is developed aiming at high navigation precision requirement of spacecraft formation flying. It uses stereo vision camera attached on the tracking craft as measurement sensor, gets the relative location of target craft in the tracking craft body r...

A careful intercomparison of the relative analyzing power of five electron beam polarimeters was performed with the CEBAF accelerator at the Thomas Jefferson National Accelerator Facility (JLab) during a dedicated two day machine development period. This is the first time such a high precision comparison between polarimeters of the Mott, Compton, and Møller type has been made. A Wien– style spi...

Precision and accuracy of the subjective visual vertical (SVV) modulate in the roll plane. At large roll angles, systematic SVV errors are biased toward the subject's body-longitudinal axis and SVV precision is decreased. To explain this, SVV models typically implement a bias signal, or a prior, in a head-fixed reference frame and assume the sensory input to be optimally tuned along the head-lo...

 In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...

The continuous use of adaptive algorithms is strongly dependent on their behavior in finite-precision environments. We study the nonlinear round-off error accumulation system of the conventional RLS algorithm and we derive bounds for the relative precision of the computations and the accumulated round-off error, which guarantee the numerical stability of the finite-precision implementation of t...

In this paper we describe mechanical and electronic design of a precision, 2-DOF robot manipulator. The manipulator is one of a wide variety of modular robotic agents in the minifactory, a rapidly depoyable precision assembly system under development in our laboratory. The manipulator, in cooperation with another type of 2-DOF robot, termed a courier, can perform 4-DOF assembly operations emula...
