More precisely, the Solar System itself is moving through what is sometimes called the "local interstellar cloud" at that speed, so space scientists measure the wind as would a motorcyclist speeding down the highway. The particles ... SJ Dick 被引量: 0发表: 2019年 WithintheMagnificenceofthe...
The modern society relies on the Global Navigation Satellite System (GNSS), which measures the position of a receiver using 1.2 or 1.5 GHz signals from multiple satellites. The errors of the measured position depend on the total electron content (TEC) because the group speed of the radio waves...
The atomic structure is often compared to a miniaturesolarsystem. 原子结构时常被比喻为微型太阳系. 《现代汉英综合大词典》 the heliocentric model of thesolarsystem 太阳系的日心模型 《牛津高阶英汉双解词典》 the planets of oursolarsystem 太阳系的行星 ...
On the other hand, as a promising solar thermal power generation system, the off-design model of the SEGS has not been established yet. Without a mathematic model of the whole system at part-load operation, it is impossible to predict the optimum working conditions. So far most of the work...
Hubble Space Telescope (HST) moving target observations are planned using the 'Percy' interactive computer program. Percy provides ephemeris and geometrical even information about solar system objects including the Sun, major planets and their natural satellites, comets, and asteroids. While Percy contain...
They can therefore be tested, by comparing their outcomes with the observed architecture of the Solar System—not only the present-day orbits of the planets, but also the orbits and different properties of various populations of comets and asteroids. For example, the ‘Nice model’ (Gomes et ...
A novel model of gravity is proposed and developed by modifying general relativity through propagating the gravitational field in an entirely analogous way... JP Merrison - 天文学与天体物理学国际期刊(英文) 被引量: 0发表: 2016年 Solar System tests of Ho?ava-Lifshitz black holes the classical te...
Proposed system modelling In this paper, two systems are proposed. The first one consists of a PV station connected to a single DC-DC converter. While in another system, each string is connected to a separated DC-DC converter. PV cell engineering model ...

There was, however, a challenge to deal with in moving to the USA. As Iris had just finished her medical training, I was essentially asking her to redo all her qualifying exams and start over in a different language, culture, and healthcare system. We made a deal: if she would not fi...
