Modern computer hardware does still interpret machine languages, which are not very far from the von Neumann paradigm. To illustrate the possibilities of hardware structures directly interpreting a high level language (HLL) we report on a BASIC computer, “Abacus”, constructed in this laboratory. Design considerations to obtain hardware which(More)
In this paper we discuss the design, control, and experimentation of internally-actuated rovers for the exploration of low-gravity (micro-g to milli-g) planetary bodies, such as asteroids, comets, or small moons. The actuation of the rover relies on spinning three internal flywheels, which allows all subsystems to be packaged in one sealed enclosure and(More)
The aim of this work was to synthesize and investigate properties of a novel dimethacrylic monomer based on bioderived alicyclic diol--isosorbide. Its potential as a possible substitute of 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]propane (BISGMA), widely used in dental restorative materials and suspected for toxicity was assessed. The novel(More)
