— Research and development of technologies supporting subscriber location identification has rapidly increased around the world. A technology demonstrator was developed for wireless location estimation in IS-95 CDMA wireless cellular systems. Field measurements were used to evaluate the performance of the developed technology demonstrator. Interim results,(More)
The feeding ecology and habitat use of the most frequently sighted and/or regularly reported stranded or by-caught toothed whale species of the North Western Iberian Peninsula (NWIP) were examined, with a special focus on their trophic position (TP) and relationships with their prey. With this aim, the stable isotope ratios of carbon (δ 13 C) and nitrogen(More)

We used cadmium 27 (Cd) and stable isotope ratios (δ 13 C and δ 15 N) as ecological tracers to assess degree(More)
