This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Airborne gamma-ray spectrometry

Hovgaard, Jens

Technical University of Denmark — 1998

A new method - Noise Adjusted Singular Value Decomposition, NASVD - for processing gamma-ray spectra has been developed as part of a Ph.D. project. By using this technique one is able to decompose a large set of data - for example from airborne gamma-ray surveys - into a few spectral components

A New Method for Processing Airborne Gamma Ray Spectrometry Data for Mapping Low Level Contaminations

Aage, Helle Karina; Korsbech, Uffe C C; Bargholz, Kim; Hovgaard, Jens

Applied Radiation and Isotopes — 1999, Volume 51, Issue 6, pp. 651-662

A new technique for processing airborne gamma ray spectrometry data has been developed. It is based on the noise adjusted singular value decomposition method introduced by Hovgaard in 1997. The new technique opens for mapping of very low contamination levels. It is tested with data from Latvia
