- We report a search for gamma rays emanating from Coulomb excitation of fast (30-46 MeV/u) radioactive projectiles He-8, Be-11,Be-12,Be-14 interacting with a lead target. These are clearly identified by their Doppler shift. The 320 keV 1/2(-) --> 1/2(+)gamma transition from Be-11 was observed with a cross-section of 191 +/- 26 mb which is noticeably less than expected from the known lifetime and in the perturbation limit of pure Coulomb excitation. In the other nuclei rather stringent upper limits of 0.01 to 0.2 Weisskopf units, are placed on the hypothetical transition to 1(-) states.

An overview of the PICASSO project research activities in speaker verification for telephone applications
- 1999
-
Konferensbidrag (refereegranskat)abstract
- This paper presents a general overview of the current research activities in the European PICASSO project on speaker verification for telephone applications. First, the general formalism used by the project is described. Then the scientific issues under focus are discussed in detail. Finally, the paper briefly describes the Picassoft research platform. Along the article, entry points to more specific work also published in the Eurospeech’99 proceedings are given.

The CAVE-WP4 generic speaker verification system
- 1998
-
Ingår i: RLA2C 1998 - Speaker Recognition and its Commercial and Forensic Applications. - : International Speech Communication Association. ; , s. 202-205
-
Konferensbidrag (refereegranskat)abstract
- This papers describes the generic speaker verification system that was developed within Work Package 4, which was responsible for Research and Technology improvements for Speaker Verification in the CAVE project. With this perspective, different SV algorithms were implemented in a common HMM framework and compared on several databases. This paper is concerned with the design of this generic system and not with the experiments we performed using the system. It shows the importance of having a common and generic package for cooperative research. We intend to make the Generic System available to the research community.

Techniques for a priori decision threshold estimation in speaker verification
- 1998
-
Konferensbidrag (refereegranskat)abstract
- A key problem for field applications in speaker verification is the issue of a priori threshold setting. In the context of the CAVE project several methods for estimating speakerindependent and speaker-dependent decision thresholds were compared. Relevant parameters are estimated from development data only, i.e. without resorting to additional client data. The various approaches were tested on the Dutch SESP database.
