WebAug 21, 2014 · In this note, we analyze this edge density problem for directed graphs, where the chromatic number χ ( D) of a digraph D is defined to be the fewest number of colours needed to colour the vertices of D so that each colour class induces an acyclic subgraph. For each k ≥ 3, we construct an infinite family of sparse k -critical digraphs for ...

WebHD (high density) binoculars come with a special lens component that reduces chromatic aberration and produces crisper, clearer views. If you’re a birder, digiscoping lover, or sailor, paying a premium for high-quality views should be your very next move. WebNov 23, 2024 · In this work, we propose a combined method to implement both modulation format identification (MFI) and optical signal-to-noise ratio (OSNR) estimation, a method based on density-based spatial clustering of applications with a noise (DBSCAN) algorithm. The proposed method can automatically extract the cluster number and density …
WebThe density of a glass helps determine the weight of the optical assembly and, along with lens diameter, becomes critical for weight sensitive applications. When dealing with applications involving extreme temperatures and quick temperature differentials, a glass' coefficient of expansion also becomes a key factor. WebMay 5, 2010 · Plastic (CR-39) and Crown Glass are considered base index with indices of 1.498 and 1.52 respectively. Materials with an index between 1.53 and 1.57 are sometimes considered mid-index, while 1.58 and greater is considered high-index. More frequently, however, anything over 1.53 is called high-index.
