AbstractIndirect methods of detection of exo-planets (by radial velocity, astrometry, occultations,...) have revealed recently the first cases of exo-planets, and will in the near future expand our knowledge of these systems. They will provide statistical informations on the dynamical parameters: semi-major axis, eccentricities, inclinations,... But the physical nature of these planets will remain mostly unknown. Only for the larger ones (exo-Jupiters), an estimate of the mass will be accessible. To characterize in more details Earth-like exo-planets, direct detection (i.e., direct observation of photons from the planet) is required. This is a much more challenging observational program. The exo-planets are extremely faint with respect to their star: the contrast ratio is about 10−10at visible wavelengths. Also the angular size of the apparent orbit is small, typically 0.1 second of arc. While the first point calls for observations in the infrared (where the contrast goes up to 10−7) and with a coronograph, the latter implies using an interferometer. Several space projects combining these techniques have been recently proposed. They aim at surveying a few hundreds of nearby single solar-like stars in search for Earth-like planets, and at performing a low resolution spectroscopic analysis of their infrared emission in order to reveal the presence in the atmosphere of the planet of CO H2O and O3. The latter is a good tracer of the presence of oxygen which could be, like on our Earth, released by biological activity. Although extremely ambitious, these projects could be realized using space technology either already available or in development for others missions. They could be built and launched during the first decades on the next century.

The intensity of a specrtal line from an optically thin plasma such as the outer atmosphere of the sun depends on both the atomic properties of the atomic ion responsible for the line and the physical nature of the plasma. In this paper we discuss the various ways in which the measured spectral intensities from the sun are used to discover something about the nature of the sun’s atmosphere. The technique has been referred to as the emission measure method. It has important limitations in terms of the accuracy of the specrtal data as well as the atomic data. We discuss some of these and suggest methods by which they may be assessed. The technique is illustrated by application to real observations from a number of authors.

Abstract This article provides an analysis of a class of failures observed during the SEMATECH-sponsored Test Methods Experiment. The analysis focuses on use of test-based failure analysis and IDDQ signature analysis to gain insight into the physical mechanisms underlying such subtle failures. In doing so, the analysis highlights techniques for understanding failure mechanisms using only tester data. In the experiment, multiple test methods were applied to a 0.45 micrometer effective channel length ASIC. Specifically, ICs that change test behavior from before to after burn-in are studied to understand the physical nature of the mechanism underlying their failure. Examples of the insights provided by the test-based analysis include identifying cases where there are multiple or complex defects and distinguishing cases where the defect type is likely to be a short versus an open and determining if the defect is marginal. These insights can be helpful for successful failure analysis.

Introduction. The lack of a coherent systemology law does not enable the use of evidence-based formalization to solve the basic theoretical problems of law interpretation and enforcement. The development of an appropriate formal-theoretical apparatus is possible on the basis of a productive systemological concept. The justification of this concept is based on the study of philosophical bases and fundamental principles (integrity, dynamic equilibrium, feedback, etc.) and the use of logical and linguistic methods of problem-oriented system approach. Theoretical Basis. Methods. The conceptual and logical modeling of legal ergasystems, the systems analysis and resolution of the theory-applied base of technology of two-tier legal regulation; the synthesis and modification of private scientific results of the author published in 2000–2019, with copyright in the author’s scientific works and educational publications. Results. The contemporary conceptual variant of combined “ICS”-approach (“information, cybernetic and synergetic”) as a general methodology of analysis and optimization of legal ergasystems, as characterized by the following conditions: the substantiation of the appropriate three-part set of methodological research principles, corresponding to the triple-aspect physical nature of the study of complex legal systems as ergasystems; the clarification of the conceptual and logical model of the legal ergasystem taking into account the fundamental feedback principle; the definition of the law of necessary diversity of William R. Ashby is justified and corresponding conditions of realize of effective technology of two-level (normative and individual) legal regulation; the definition of basic concepts and methodological principles of modern systemology of legal regulation; the justification of the functional organization of the Invariant Rational Control Loop. Discussion and Conclusion. A developed conceptual object-oriented version of combined “ICS”-approach for analysis and optimization of legal ergasystems is a methodological basis for the development of a working formal-theoretical apparatus of legal regulation systemology. This will formalize the decisions of the main theoretical problems of law interpretation and enforcement, as well as developing and implementing special information and legal technologies based on the concept of information and functional databases and knowledge. This will in turn ensure the information increases the effectiveness of the system of legal regulation of public relations as an information and cybernetic system subject to the subjective organizing process of human activity and the objective synergetic processes of disorganization.

The article describes the approach and topical issues of synthesis of highly efficient transportable systems for search and determination of coordinates in the areas of elements falling, separated from the missiles, taking into account the dislocation of pre-empted areas of fall and physical conditions in their territories. The principles of these systems are based on the rational integration of traditional and non-traditional information sensors of different physical nature, which record the moments of landing of separated parts of the missiles.

The Mind

Although Locke’s Essay is primarily a discourse in logic, he says enough about the physical nature of things to construct a theory of the nature of things. As a virtuoso, physics replaces metaphysics in his philosophical system. His ontology, however, includes not only bodies, but God and finite spirits, and its major achievement is to prove the existence of God and demonstrate his immateriality. Perhaps encouraged by reading Cudworth, Locke was confident that our faculty of reason is sufficient to refute materialism and atheism. As to the nature of bodies, Locke finds empirical evidence that solidity or impenetrability is their most evident quality. The idea of superaddition is central to Locke’s speculative or divine physics. But although such insights may elevate the mind to God, Locke’s physics is theoretically sterile, although it may have beneficial practical uses.

Rejecting some old misconceptions (such as the “pulling” gravitation that ravaged classical physics) the Inertial-Gravitational theory supported by the Micro-quanta paradigm incorporates both the relativistic concepts of Mass - Momentum - Energy and the quantic Inertial Model of the particle mass. The flux of micro-quanta supports primarily the physical interaction that generates the Inertial forces defined by Newton. Scholars believing that Inertial forces originate from the properties of the empty space, do not pertain to the community of physicists believing on Newton’s Inertial Law. This great ancient physicist admitted he was unable to explicit the physical nature of his Law of Inertia (“Hypotheses non fingo”). However, marking the difference between “empty” and “absolute” space, he remained in his conviction that some unknown physical reality originates (in the absolute space) the inertial forces upon accelerated masses. At present, Micro-quanta paradigm describes the quantic objects that generate through collisions the physical inertial forces on particles. Since the flux of micro-quanta fills all space, there is no need to refer these collisions to some external System of reference. The relative velocity between quanta and particles comes out from the momentum that micro-quanta confer to particles. By this reason the Micro-quanta paradigm defines on pure dynamical bases the relativistic formalism that Special relativity derived from kinematics, so creating flaws that produced the well known paradoxes. To reveal the micro-quanta it's not necessary to devise particular experiments. The technique of the accelerometers has given many evidences of the physical reality guessed by Newton to explain inertial forces exerted on masses. Since the action of micro-quanta is always manifested in statistical terms, classical and relativistic physics allowed to describe Inertia and Gravitation without knowing the quantic nature of these phenomena. The micro-quanta Paradigm shows in particular the proportionality between cross section and mass (ratio Au) of all particles colliding with micro-quanta. To the aim of calculating the transmission across matter of micro-quanta and neutrinos (which show the same nature) the only unknown quantity is the numerical value of the ratio Au. Recalling that micro-quanta flux fills all space, it appears also interesting to search about neutrino collisions with micro-quanta flux as possible cause of the oscillations phenomena that occur during neutrino travels across the (so called) astronomic “empty” space. A quantitative indication on the ratio Ao is found in this paper from an experimental measurement of the solar neutrino flux interacting with the Earth mass in the course of the Borexino research carried out at Gran Sasso National Laboratory.

Study of rheological properties of concrete mixtures based on modified cement systems in order to determine process parameters. Methodology. To study structural-mechanical properties of modified concrete mixtures of different consistency at their horizontal vibrating displacement an oscillatory viscometer was designed. Results. The optimization of the process of vibration displacement of concrete mixtures with the specification of parameters of vibration impacts taking into account structural-mechanical properties of the mixture is performed. It has been established that the viscosity of the modified cement system of the concrete mixture is a variable quantity, which depends on the parameters of the vibration impacts. Scientific novelty. The mechanism of interaction of the modified concrete mixture with the form and the table vibrator during its vibration compaction is determined. On the basis of this, a model of concrete laying process control is proposed, that allows to predict the ability to form a dense concrete structure. Practical significance. Disclosed physical nature of the process of vibrating displacement of modified concrete mixtures using the principles of physical-chemical mechanics of concrete allows reasonably choose the best options for vibration impacts.
