We run a selection of algorithms on two state-of-the-art 5-qubit quantum computers that are based on different technology platforms. One is a publicly accessible superconducting transmon device (www. RESEARCH ibm.com/ibm-q) with limited connectivity, and the other is a fully connected trapped-ion system. Even though the two systems have different native quantum interactions, both can be progr...

Software inspection is well-known as an eeective defect nding process. One avenue of inspection research concerns tool support, with the aim of further increasing its eeciency and eeectiveness. This has resulted in the production of a number of prototype tools. In general, however, these tools are poorly evaluated and the performance gain which these tools may provide has not been quantiied. Th...

A method for detecting the dimension of a dynamical system encompassing simultaneously two distinct discrete time series is presented. The time series are provided by the same observable taking distinct and independent initial conditions or they can be formed by realizations of different observables measured simultaneously in a symmetric attractor. The method is derived from an extension of the...

– We study the direct enstrophy cascade in a two-dimensional flow generated in an electromagnetically driven thin layer of fluid. Due to the presence of bottom friction, the energy spectrum deviates from the classical Kraichnan prediction k. We find that the correction to the spectral slope depends on the thickness on the layer, in agreement with a theoretical prediction based on the analogy wi...

In this work a novel synchronisation scheme for chaotic systems is presented. Taking inspiration from the system decomposition approach, the master and slave are connected via a switch which allows to alternate the signal fed into the slave between the master signal and the slave signal itself. The switching frequency has been taken into account as a control parameter to characterise the synchr...

The experimental two-level morphology of Estonian is under development at the University of Tartu. The language description, consisting of 45 two-level rules and over 200 lexicons has been implemented and tested using Xerox finite-state tools twolc and lexc. The root lexicons cover 400 most frequent stems at the present stage of development. The software has been designed to update the lexicon ...

1 Two puzzles Relating standard linguistic data to theory is hard; making experimental data bear on the theory is even harder. Two difficult problems are central, one relating to experimental design, and the other, to the interpretation of results. In this short note, I discuss these problems in the context of specific studies in experimental syntax and semantics. I begin with an experimental d...

We address the trajectory planning problem for a task which requires positioning and orienting an object firmly grasped by two hands at a visually specified goal configuration in the horizontal plane. The motor task involves three degrees of freedom (two translational and one rotational), and the motions of the arms are constrained by the physical coupling through the held object. Experimentall...

In this paper, we perform the experimental characterization of two-axis MEMS scanners driven by radial vertical combdrive actuators. The dc scan ranges are limited by the pull-in effect. Each scanner utilizes a cross-bar spring structure to achieve two rotational degrees of freedom (DOFs) without employing any gimbal. Both the actuators and torsion springs are hidden underneath the mirror to ob...

In the context of algebraic statistics an experimental design is described by a set of polynomials called the design ideal. This, in turn, is generated by finite sets of polynomials. Two types of generating sets are mostly used in the literature: Gröbner bases and indicator functions. We briefly describe them both, how they are used in the analysis and planning of a design and how to switch bet...
