Abstract The change in the kinetic moment of a material body is considered regarding to classical and quantum mechanics. The possibility of creating the propulsion system in terms of energy efficiency exceeding the photon engine has been theoretically proved. The proposed new principle of motion is based on the law of conservation of angular momentum and is fully consistent with the basic fundamental laws of physics. It is proposed to use the radiation/absorption of streams of low-energy particles with spin in the direction perpendicular to the movement of the material body. The practical implementation of this idea is confirmed by the presence of promising approaches to solving the problem of quantizing gravity (string theory, loop quantum gravity, etc.) recognized by the world scientific community and by the successful results of experiments conducted by the authors with the motion of bodies in a vacuum chamber. The proposed idea, the examples and experiments has given grounds for the formation of new physical concepts of the speed, mass and inertia of bodies. The obtained results can be used in experiments to search for elementary particles with low energy, to explain a number of physics phenomena and to develop transport of objects based on new physical principles.

Kinetic Moment

The controlled motion of a body in a central gravitational field without mass flow is considered. The possibility of moving the body in the radial direction from the center of attraction due to changes in the kinetic moment relative to the center of mass of the body is shown. A scheme for moving the body using a system of flywheels located in the same plane in near-circular orbits with different heights is proposed. The use of the spin of elementary particles is considered as flywheels. It is proved that using the spin of elementary particles with a Compton wavelength exceeding the distance to the attracting center is energetically more profitable than using the momentum of these particles to move the body. The calculation of motion using hypothetical particles (gravitons) is presented. A hypothesis has been put forward about the radiation of bodies during accelerated motion, which finds indirect confirmation in stellar dynamics and in an experiment with the fall of two bodies in a vacuum. The results can be used in experiments to search for elementary particles with low energy, explain cosmic phenomena and to develop transport objects on new physical principles.

In this contribution, I will examine the interaction between stellar rotation and pulsation. I begin with a brief review of the non-rotating case, emphasizing the character of pulsations as azimuthally-propagating waves. I then go on to discuss how these waves are modified under the influence of the centrifugal and Coriolis forces. Through simple arguments, I outline the conditions under which each force can become significant in determining the wave dynamics. Particular attention is paid to the Coriolis force, since it is responsible for the formation of a waveguide, which confines the pulsation to a narrow band centered on the stellar equator. Using the example of a prograde sectoral pulsation mode, I explain the basic physical principles underlying this trapping.The Coriolis force is also responsible for the existence of Rossby waves, which are not found in non-rotating stars. I demonstrate how these waves may be understood in terms of a conservation law for angular momentum, and review their most important characteristics. I then examine how rotation modifies the frequencies of pulsation, and explain how observations of such modifications can provide information regarding a star's rotation rate. To conclude, I focus on the converse of the pulsation-rotation interaction: how the transport of angular momentum by pulsation might be important in determining the evolution of a star's rotation profile.

Vertically-aligned carbon nanotube (VACNT) pads have recently received widespread attention for use as contact surfaces in material handling processes that involve the transfer of bare silicon wafers. Such processes will benefit from the strong friction force interactions and minimal adhesion force offered by these pads, allowing the wafer to be picked up, carried, and quickly placed, without encountering problems which may arise due to excessive adhesive forces. Despite these benefits, practical implementation has been hindered because VACNTs have nonlinear mechanical characteristics which are still not well understood. Consequently, significant attention has been devoted to fully understand and determine the behaviors associated with their nonlinear dynamic mechanical properties. Along this line, several experimental techniques are applied in this paper to further develop a comprehensive understanding of the mechanical behavior of these pads under compressive loading. It is important to note that the samples used in this testing are not standard VACNTs, but have been grown separately from the final substrate on which they are mounted during testing. After growth, the samples are turned upside-down and fixed so that the bottom ends of all VACNTs are planar and present an ultra-flat top surface for contact during manipulation. The tests performed in this research include a low energy impact test and position controlled load-displacement testing with both constant and sinusoidal velocity loading and unloading. Through these testing procedures, the dependencies of the VACNT material properties to compression depth and displacement rate are observed and an attempt is made to incorporate them into a continuous model. For this, the results from the low energy impact testing provide grounds to state the nature of the nonlinear behavior in our VACNTs. By interrogating the available data from each testing technique, a combination of information provided by the theoretical energy balance and the identified coefficients from the Levenberg-Marquardt curve-fitting algorithm is then applied to generate a parametrized phenomenological model of the VACNT pad behavior. The proposed identified model is continuous and reasonably accounts for the overall material behavior as seen in the experimental data. The validity of this model is shown by means of normalized vector correlation of over 99% between the results of the numerical simulations and the existing experimental data. The material behaviors observed in this research qualitatively support those of several earlier investigators who have previously recognized the complex dissipative behavior of VACNTs. The proposed work itself paves the road for developing a useful engineering model of VACNT pad dynamics which will enable their introduction to mechanical applications in industry.

With mounting concerns over climate change and urban population growth, the demand for sustainable housing based on low-energy designs is steadily increasing. A variety of low-energy design methods have been developed to reduce energy and resource consumption; however, research shows that the implementation of such methods has been surprisingly limited. In addition, while the degree of housing density is understood to have an impact on low-energy designs, what that impact is and how it can be strategically applied have not been adequately researched. This research examines how low-energy designs are applied in housing types with various densities in temperate climates, identifies the issues and problems pertaining to the implementation of passive and active design strategies. This research uses a survey, which asks design practitioners to rate the merits of various low-energy design strategies and assesses how often these approaches are implemented in practice. The study uncovers discrepancies between perceived importance of low-energy design aspects and their practical implementation, finding that certain low-energy strategies can be more effective when they are incorporated in an early stage of the design process.

The possibility of stabilizing an unstable uniform rotation in a resisting medium of a "sleeping" Lagrange gyroscope using a rotating second gyroscope and elastic spherical hinges is considered. The "sleeping" gyroscope rotates around a fixed point with an elastic recovery spherical hinge, and the second gyroscope is located above it. The gyroscopes are also connected by an elastic spherical restorative hinge and their rotation is supported by constant moments directed along their axes of rotation. It is shown that stabilization will be impossible in the absence of elasticity in the common joint and the coincidence of the center of mass of the second gyroscope with its center. With the help of the kinetic moment of the second gyroscope and the elasticity coefficients of the hinges, on the basis of an alternative approach, the stabilization conditions obtained in the form of a system of three inequalities and the conditions found on the elasticity coefficients at which the leading coefficients of these inequalities are positive. It is shown that stabilization will always be possible at a sufficiently large angular velocity of rotation of the second gyroscope under the assumption that the center of mass of the second gyroscope and the mechanical system are below the fixed point. The possibility of stabilizing the unstable uniform rotation of the "sleeping" Lagrange gyroscope using the second gyroscope and elastic spherical joints in the absence of dissipation is also considered. The "sleeping" gyroscope rotates at an angular velocity that does not meet the Mayevsky criterion. It is shown that stabilization will be impossible in the absence of elasticity in the common joint and the coincidence of the center of mass of the second gyroscope with its center. On the basis of the innovation approach, stabilization conditions were obtained in the form of a system of three irregularities using the kinetic moment of the second gyroscope and the elastic coefficients of the hinges. The condition for the angular momentum of the first gyroscope and the elastic coefficients at which the leading coefficients of these inequalities are positive are found. It is shown that if the condition for the angular momentum of the first gyroscope is fulfilled, stabilization will always be possible at a sufficiently large angular velocity of rotation of the second gyroscope, and in this case the center of mass of the second gyroscope can be located above the fixed point.
