Stratigraphic Thickness

Given the state of homogeneous total strain or average total strain of a deformed unit, its stratigraphic thickness can be readily determined. The necessary theoretical development is presented herein, together with a general discussion of the necessary equations. It is shown that the practice of destraining lines of true thickness of deformed strata is theoretically sound only if the bedding surface is a principal plane of deformation.

The direct determination of the steady state response for linear time invariant (LTI) systems modeled by multibond graphs is presented. Firstly, a multiport junction structure of a multibond graph in an integral causality assignment (MBGI) to get the state space of the system is introduced. By assigning a derivative causality to the multiport storage elements, the multibond graph in a derivative causality (MBGD) is proposed. Based on this MBGD, a theorem to obtain the steady state response is presented. Two case studies to get the steady state of the state variables are applied. Both cases are modeled by multibond graphs, and the symbolic determination of the steady state is obtained. The simulation results using the 20-SIM software are numerically verified.

Wood’S Alloy

The article examines the process of crystallization of Wood alloy using the ultrasonic method. The dependence of the determination of the speed of sound in three aggregate states of the alloy (liquid, solid, transition (liquid-solid)) was derived. The relation-ship with the amplitude values of the sound signal, a single pulse in determining the speed of sound, as well as in determining the state of the alloy is carried out. The data obtained allow us to analyze the state of the alloy and the measurement time and the specified frequency range directly in the process of crystallization.

The realization of existing projects of on-orbit servicing and the development of new ones is a steady trend in the development of space technology. In many cases, on-orbit service clients are objects that exhibit an undesired rotary motion, which renders their servicing difficult or impossible. The problem of on-orbit service object motion control determines the topicality of studies aimed not only at the refinement of methods and algorithms of controlling both the translational and the rotary motion of an object, but also at the development and refinement of methods of onboard determination of the object – service spacecraft relative motion parameters. This paper overviews the state of the art of the problem of object motion parameter determination in on-orbit servicing tasks and existing methods of object motion control and angular motion damping and specifies lines of further investigations into the angular motion control of non-cooperative service objects. Based on the analysis of publications on the subject, the applicability of onboard means for object motion parameter determination is characterized. The analysis of the applicability of methods of remote determination of the parameters of an unknown non-cooperative object from a service spacecraft shows that they are at the research stage. The input data for the verification of methods proposed in the literature were simulated or taken from ground experiments or previous missions. Contact and contactless methods of angular motion control of non-cooperative on-orbit service objects are considered. From the state of the art of investigations into the contactless motion control of on-orbit service objects it may be concluded that the most advanced contactless method of motion control of an on-orbit service object is a technology based on the use of an ion beam directed to the object from an electrojet engine onboard a service spacecraft. Lines of further investigations into non-cooperative object motion control are proposed.

This article analyzes the choice-of-law interests of specific and potential participants in the relations of intellectual property rights and the state in order to establish the closest connection of the above type of relation with the state, whose law should be applied. Taking into account the directionality of significant choice-of-law interests, advantages and disadvantages of territorial and universal approaches, a theoretically based solution is proposed for the formation of a general choice-of-law rule on the law to be applied to the relation of intellectual property rights. It was revealed in the study that the diversity of the relations of intellectual property rights (their obligatory and non-obligatory, property and personal non-property nature, other differences in legal features) does not automatically generate a multidirectionality of significant choice-of-law interests that should be taken into account when establishing a close connection of the above type of the relation with the state for determination of applicable law, does not prevent the formation of a general choice-of-law rule for the relations of intellectual property rights in general and does not unequivocally testify in favor of the specialization of its binding. However, the diversity of the relations of intellectual property rights should be examined and evaluated for the feasibility and limits of exceptions from the general choice-of-law rule and the development of special rules for resolving certain private of the relations of intellectual property rights.
