This paper presents a case study on the application of data mining to the problem of detecting ecosystem disturbances from vegetation cover data obtained from satellite observations. We describe two ...anomaly detection approaches-moving average and random walk-for detecting such events. We also illustrate how clustering can be used to locate similar incidents of disturbance events. Finally, we present a clustering-based framework to aid the visual exploration of ecosystem disturbances from high resolution data.
Cognitive Informatics (CI) is a transdisciplinary enquiry of computer science, information sciences, cognitive science, and intelligence science that investigates into the internal information ...processing mechanisms and processes of the brain and natural intelligence, as well as their engineering applications in cognitive computing. This paper summarizes the presentations of a set of 14 position papers in the ICCI'09 Panel on Cognitive Informatics and Cognitive Computing contributed from invited panelists who are part of the world's renowned researchers and scholars in the field of cognitive informatics and cognitive computing.
The title compound, C12H11N5O6S, has a basal plane, which contains a urea group and a pyrimidine ring. The S atom lies out of the plane of the urea moiety, and the S—N—C—N torsion angle is 160.6 ...(2)°. An extended π‐conjugated system is formed between the urea moiety and the pyrimidine ring.
The title compound, C14H14N4O6S, has a basal plane which contains a urea group, a pyrimidine ring and the S atom. The overall conformation is V‐shaped. There exists a pseudo‐six‐membered ring ...involving the pyrimidine ring and the urea moiety as a result of an intramolecular N—H⋯N hydrogen bond. The molecules form dimers via an intermolecular N—H⋯N hydrogen bond and π–π interactions stabilize the crystal structure.
