Three kilns and a collection of baked bricks from Italian archaeological sites have been studied for archaeointensity determination using the Thellier method as modified by Coe. All sites are dated based on archaeological information and... more
— Klang Valley, a heavily industrialized urban area in Malaysia, has experienced severe haze episodes since the early 1980s. Total Suspended Particulate matter (TSP) is used in studying this phenomenon. Three severe haze episodes during... more
Traditionally multi-variate normal distributions have been the staple of data modeling in most domains. For some domains, the model they provide is either inadequate or incorrect because of the disregard for the directional components of... more
A multimedia framework and model are employed, to embrace the interactive and visual presentation of a series of case-studies with large conventional (static), and multi-mode (dynamic) data sets. This identifies multifaceted presentation... more
... Hilborn, 1997). In contemporary stock assessments, estimation of natural mortality seems feasible by integrating different types of data into the analysis ([Fournier et al., 1998] and [Hampton and Fournier, 2001]). For example ...
We define a distribution on the unit sphere S d−1 called the elliptically symmetric angular Gaussian distribution. This distribution, which to our knowledge has not been studied before, is a subfamily of the angular Gaussian distribution... more
We study some elementary statistics of wind direction fluctuations in the atmosphere for a wide range of time scales (10-4 sec to 1 h), and in both vertical and horizontal planes. In the plane parallel to the ground surface, the direction... more
Seismic data acquisition for the MARCONI project took place in 2003 in the eastern half of the Bay of Biscay. The overall goal of the multichannel experiment was to collect seismic data to elucidate the structure and evolution of the... more

The Korba aquifer, located in the north of Tunisia, suffers heavily from salinization due to seawater intrusion. In 2000, the aquifer was exploited from more than 9000 wells. The problem is that no precise information was recorded... more
