Spectral comparison of large urban graphs

The spectrum of an axial graph is proposed as a means for comparison between spaces, particularly for measuring between very large and complex graphs. A number of methods have been used in recent years for comparative analysis within large sets of urban areas, both to investigate properties of specific known types of street network or to propose a taxonomy of urban morphology based on an analytical technique. In many cases, a single or small range of predefined, scalar measures such as metric distance, integration, control or clustering coefficient have been used to compare the graphs. While these measures are well understood theoretically, their low dimensionality determines the range of observations that can ultimately be drawn from the data. Spectral analysis consists of a high dimensional vector representing each space, between which metric distance may be measured to indicate the overall difference between two spaces, or subspaces may be extracted to correspond to certain features. It is used for comparison of entire urban graphs, to determine similarities (and differences) in their overall structure. Results are shown of a comparison of 152 cities distributed around the world. The clustering of cities of similar properties in a high dimensional space is discussed. Principal and nonlinear components of the data set indicate significant correlations in the graph similarities between cities and their proximity to one another, suggesting that cultural features based on location are evident in the city form and that these can be quantified by the proposed method. Results of classification tests show that a city’s location can be estimated based purely on its form. The high dimensionality of the spectra is beneficial for its utility in data-mining applications that can draw correlations with other data sets such as land use information. It is shown how further processing by supervised learning allows the extraction of relevant features. A methodological comparison is also drawn with statistical studies that use a strong correlation between human genetic markers and geographical location of populations to derive detailed reconstructions of prehistoric migration. Thus, it is suggested that the method may be utilised for mapping the transfer of cultural memes by measuring comparison between cities

The life of Jetsun Lochen Rinpoche

Jetsun Lochen Rinpoche was presumably born in 1865 and died in 1951 and was one of the most famous female religious masters in traditional Tibet. Among her various religious roles were those of pilgrim, professional singer of manis (mani pa), healer, a messenger from the land of the dead (‘das log), yogini, nun, lineage-holder, visionary, performer of miracles (siddha), emanation, treasure-finder, religious teacher and head of a nunnery. In short, she had all the signs and charisma of a holy person. She was popularly known as Jetsun or Ani Lochen (A ne Lo chen), and among her several other names Rigdzin Chönyi Sangmo (Rig ’dzin chos nyid bzang mo) was frequently used. The main textual source regarding Jetsun Lochen Rinpoche’s life is her autobiography (271 folios). Lochen was repeatedly requested by her disciples to tell her life-story, but only in 1937, when she was requested by Drubchen Dawa Dorje Rinpoche (Grub chen Zla ba rdo rje rin po che), whom she recognized as the reincarnation of her root-lama Pema Gyatso (Padma rgya mtsho, 1829-1889/90), did she consent. Although she started telling her life-story in 1937, she abandoned the project and apparently did not take it up again until about twelve years later, in 1949, when she again was requested by Drubchen Dawa Dorje and four named diciples. Lochen told the story of her life up to the 25th day of the 11th month of 1949. The nun-teacher Thinlay (rGan ‘Phrin las) wrote the draft and it was completed by Dawa Dorje Rinpoche. ..
