seismic waves are non-stationary due to its propagation through the earth. time-frequency transformsare suitable tools for analyzing non-stationary seismic signals. spectral decomposition can reveal thenon-stationary characteristics which cannot be easily observed in the time or frequency representationalone. various types of spectral decomposition methods have been introduced by some researche...

In our recent paper “A simple tool for neuroimaging data sharing,” we introduced a system for sharing DICOM data. Addressing anonymization, we mentioned DICOM Supplement 551, the National Cancer Institute deidentification profile, and the default deidentification profile in XNAT’s DICOM Browser and noted the disagreement in these various anonymization profiles. While a careful analysis of anony...

The aim of this paper is to study the (clinical) time-series data of three diseases with complex dynamics: Parkinson’s disease, Huntington’s disease and Amyotrophic Lateral Sclerosis. For this purpose, first all of the time series data are embedded in a vector space of suitable dimension and then the correlation dimension of the above mentioned diseases is estimated. The results are also compar...

RDF, a simple yet expressive data model, is widely recognised as the foundation for the Semantic Web. We revisit the RDF specification and analyse five problems: literals are not addressable, blank nodes are not addressable, reification is not semantically recognised, language tags are not addressable, and language tags can not be combined. We introduce SiRDF, a simplified data model with fewer...
