In this paper we develop a theory of disturbances induced by the stellar tidal field in a fully convective slowly rotating planet orbiting on a highly eccentric orbit around a central star. In that case it is appropriate to treat the tidal influence as a succession of impulsive tidal interactions occurring at periastron passage. For a fully convective planet mainly the l = 2 fundamental mode of...

This paper presents a new JDtthematieal model of indicated horsepower of rolling piston compressor. It is not an intergul formula but a genertl mathematical formula made out by authors calculating ia detail on the baee of former integral formula of indicated hor1epower aad parameters such as the ratio of Ieath aad diameter, the ratio of eccentric from implicit function. Ia accordance with this ...

Nonpulsed but variable X-ray emission has been detected from the binary system containing the radio pulsar PSR 1259–63 during two pointed ROSAT observations, taken five months apart. This 47.7 ms radio pulsar is in a highly eccentric (2 ∼ .85) binary system with the 10 to 15 M ̄ Be star SS2883. It is the first radio pulsar found to be in a binary system with a massive main sequence companion; it...

let $g=(v,e)$ be a connected graph. the eccentric connectivity index of $g$, $xi^{c}(g)$, is defined as $xi^{c}(g)=sum_{vin v(g)}deg(v)ec(v)$, where $deg(v)$ is the degree of a vertex $v$ and $ec(v)$ is its eccentricity. the eccentric distance sum of $g$ is defined as $xi^{d}(g)=sum_{vin v(g)}ec(v)d(v)$, where $d(v)=sum_{uin v(g)}d_{g}(u,v)$ and $d_{g}(u,v)$ is the distance between $u$ and $v$ ...

A boundary structure is observed in beds of vertically vibrated granular materials separating regions of opposite phase. This structure is investigated and it is identified as giving rise to both a global kink and hexagonal patterns. A global phase diagram of surface patterns on a vibrated bed is presented. c © 1998 Published by Elsevier Science B.V. In recent years, there has been a dramatic s...

In this research we provide the analysis of modern green wall technologies. The modular greening technology for buildings is universal invention with respect to purpose building and it applicable intended any spheres «going into nature» aims. complexity installation work constructive system quite low, which one main advantages invention. Due fact that can be installed both vertically horizontal...

In the presence of inertia-gravity waves, geostrophic and hydrostatic balance that characterises slow dynamics rapidly rotating, strongly stratified flows holds in a time-averaged sense applies to Lagrangian-mean velocity buoyancy. We give an elementary derivation this wave-averaged illustrate its accuracy numerical solutions three-dimensional Boussinesq equations, using simple configuration wh...

Magnetic fields have been widely used to control solidification processes. Here, high-speed synchrotron X-ray tomography was study the effect of magnetic on solidification. We investigated vertically upward directional an Al-Si-Cu based W319 alloy without and with a transverse field 0.5 T while sample rotating. The results revealed strong both primary α-Al phase secondary β-Al5FeSi intermetalli...
