This paper introduces the concept of a physical self-replicating machine for deployment on the Moon utilizing raw material available on the Moon. A detailed but selective review is given in order to highlight clearly the novel aspects of the concept presented. In particular, it is hypothesized that if critical components electric motors and vacuum tubes can be 3D printed from the limited repert...

Cyber-physical systems (CPS), such as automotive systems, are starting to include sophisticated machine learning (ML) components. Their correctness, therefore, depends on properties of the inner ML modules. While learning algorithms aim to generalize from examples, they are only as good as the examples provided, and recent efforts have shown that they can produce inconsistent output under small...

The High Luminosity LHC upgrade poses demanding requirements in terms of energy deposition, in particular around the high luminosity experiments where the Inner Triplet elements and the separation dipole will be exposed to unprecedented levels of radiation, challenging their reliability and lifetime. Dedicated Monte Carlo studies have been conducted in order to characterize the debris-machine i...

Components of the machine-readable dictionary can be applied in a number of information systems. The most direct applications of the kind are in wordprocessing or in "writingsupport" systems built on a wordprocessing base. However, because a central function of any dictionary is in fact data verification, there are other proposed applications in communications and data storage and retrieval sys...

This paper reports on an experiment in assembling a domainspeci c machine translation prototype system from o -the-shelf components. The design goals of this experiment were to reuse existing components, to use machine-learning techniques for parser specialization and for transfer lexicon extraction, and to use an expressive, lexicalized formalism for the transfer component. In Machine Translat...

This article describes a self-healing mechanism for statemachine based distributed components. Each component is composed of two layers: a healing (HL) and a service or functional layer (FL). At least, the functional layer must be implemented according to a statemachine specification. The healing layer has the capacity of monitoring the service layer of the component of witch it is a part and r...

The non-uniform air gap in an electrical machine caused by rotor eccentricity creates an asymmetrical flux-density distribution in the air gap. This can affect the nominal torque produced by the machine. Eccentricity also produces forces that act on the rotor which may also have an effect on the torque. Thus, it is important to know how the torque of the machine behaves. In this paper, the torq...

different methods for detecting broken bars in induction motors can be found in literature. many of these methods are based on evaluating special frequency magnitudes in machine signals spectrums. current, power, flux, etc are among these signals. frequencies related to broken rotor fault depend on slip. in industrial environment due to some phenomena - such as load oscillation, other faults an...
