Self-Index Compression in Electronic Publishing
Compression has been used typically to save disk space and bandwidth. However, from a decade ago, a new family of data structures allows applying compression to save space in main memory as well. The so-called self-indexes are an example of these new structures. They can store a text in space proportional to that of the compressed version of the same text, and at the same time, they allow searc...
متن کاملElectronic publishing: all talk and no action?
Suppose they gave a revolution and nobody came? We’re meant to be in the midst of a revolution in life sciences publishing but, for a revolution, it’s awfully quiet. For the moment at least, the ancien régime — in the form of traditional peer review and conventional commercial journals — seems to be winning. The latest fusillade came from Stanford University’s HighWire Press, which has just beg...
متن کاملModification of the Fosberg fire weather index to include drought
Abstrac t . The Fosberg fire weather index is a simple tool for evaluating the potential influence of weather on a wildland fire based on temperature, relative humidity and wind speed. A modification to this index that includes the impact of precipitation is proposed. The Keetch-Byram drought index is used to formulate a ‘fuel availability’ factor that modifies the response of the fire weather ...
متن کاملMaximal Clones on Uncountable Sets That Include All Permutations
We first determine the maximal clones on a set X of infinite regular cardinality κ which contain all permutations but not all unary functions, extending a result of Heindorf’s for countably infinite X. If κ is countably infinite or weakly compact, this yields a list of all maximal clones containing the permutations since in that case the maximal clones above the unary functions are known. We th...
