Measures for ETL processes models in data warehouses
(11/06/2009)
processes take charge of extracting the data from data sources that would be contained in the data warehouse. Due to their relevance, the quality of these processes should be formally assessed since the early stages of ...
Automatic generation of ETL processes from conceptual models
(11/06/2009)
Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...
Heterogeneous photochemical reactions of decabromodiphenyl ether
(11/03/2009)
Brominated diphenyl ethers area major class of brominated flame retardants, with production of decabromodiphenyl ether (DBDPE) contributing significantly to this total. Although little is known about the mechanisms and ...
SiC: An agent based architecture for preventing and detecting attacks to ubiquitous databases
(2009-07-01)
One of the main attacks to ubiquitous databases is the structure query language (SQL) injection attack, which causes severe damages both in the commercial aspect and in the user’s confidence. This chapter proposes the SiC ...

High-Resolution Indirect Feet–Ground Interaction Measurement for Hydraulic-Legged Robots
(10/01/2009)
Feet-ground interactions influence the legged robot's stability. In this paper, a high-resolution indirect force measurement for hydraulic-legged robots is presented. The use of pressure transducers placed at one or both ...
