While that may make suborbital travel safer, it would add significant cost and complexity to an emerging industry that has until now operated largely as the playground of billionaires and dreamy engineers.How Virgin Galactic, regulators and the public respond to this most recent tragedy will ...

In order to usher in this new paradigm, we must first understand what complexity science is, specifically in the context of Heliophysics research. Complexity is a difficult thing to define. It is often used synonymously with ‘something we do not yet know’ (Cilliers2000), a placeholder label...
The following roadmap for the maturation of QT enhanced TFT technologies is suggested based on the maturity and complexity of the individual elements. 3.3.1 Short-term goals (5 years) As the technology elements for frequency transfer are readily available for fiber and free-space links and severa...
P-Space模型是将同一条公共汽车线路上的所有车站直接相连从而表示线路的存在,通过设置边的权重(以下简称“边权”)反映车站在空间上的相对关系。C-Space模型仅考虑公共汽车线路间的关系,将线路表示为节点,边则表示两条线路之间可以换乘。 图1 简单公共汽车线网的4种拓扑模型...
Summary: In this paper, we describe a new flexible framework for state space exploration based on cooperating agents. The idea is to let various agents with different search patterns explore the state space individually and communicate information about fruitful subpaths of the search tree to each...
For example, some work in Australia suggests that humans prefer to seek green spaces with higher density and moderate vegetation complexity reflective of tree canopy rather than relatively simple open spaces more akin to large areas of grass.19 Other work has similarly found differences in ...
Given k, for each \(x_i\), we start by computing the k nearest neighbors of \(x_i\) in X using the existing metric \(d_{{\mathcal {A}}}\) of the ambient space. This step has a complexity of \({\mathcal {O}}((k+1) *n^2)\). This set is called the k-nearest ...
