Barnes-Hut-SNE

The paper presents an O(N logN)-implementation of t-SNE — an embedding technique that is commonly used for the visualization of high-dimensional data in scatter plots and that normally runs in O(N). The new implementation uses vantage-point trees to compute sparse pairwise similarities between the input data objects, and it uses a variant of the Barnes-Hut algorithm to approximate the forces be...

Synchronization Karipihkala Hut,telecommunicationssoftwareandmultimedialaboratory

This paper discusses various synchronization methods for mobile devices. It gives an overview of today’s standards, IrDA and SyncML, and presents some existing synchronization systems. Legacy synchronization methods use incompatible proprietary protocols. Recently, a standardization effort was initiated to create SyncML, an open standard for data synchronization. However, there is still a long ...

Regulation of the hut operons of Salmonella typhimurium and Klebsiella aerogenes by the heterologous hut repressors.

In merodiploid strains of Klebsiella aerogenes with chromosomal hut genes of K. aerogenes and episomal hut genes of Salmonella typhimurium, the repressor of either species can regulate the hut operons of the other species. The repression exerted by the homologous repressor on the left-hand hut operon is, in both organisms, stronger than that exerted by the heterologous repressor.

Altbestandserfassung oder Altbestandskatalogisierung ?

Die Altbestandserfassung (Umsetzung konventioneller Katalogdaten in maschinenlesbare Form), wie sie von der DFG initiiert und finanziert wird, muß in Abhängigkeit zu Fragen der Altbestandskatalogisierung gesehen werden. Der Einsatz der EDV und die Möglichkeit der Fremddatenübernahme lösen noch nicht die bibliothekarischen Probleme, sondern werfen sie erst recht auf. Die Festlegung eines Regelwe...
