Multi-sensor system using plastic optical fibers for intrinsically safe level measurements
(10/04/2004)
A system for measuring liquid level in multiple tanks using optical fiber technology has been developed. Oil field service industry or any sector requiring liquid level measurements in flammable atmospheres can be benefited ...
Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
(06/01/2001)
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
Climate change and environmental planning: Working to build community resilience and adaptive capacity in Washington State, USA
(07/01/2009)
This work focuses on the efforts being made by King County, Washington to respond to the challenges of global climate change, concentrating on both mitigation and adaptation. King County is a leader in the United States ...
Modeling Abiotic Processes of Aniline in Water-Saturated Soils
(03/18/2000)
The long-term interactions of aromatic amines with soils are important in defining the fate and transport of these compounds in the environment. Abiotic loss of aniline from the aqueous phase to the soil phase occurs with ...
Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils
(08/04/2001)
Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
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 ...
From implicit to touching interaction: RFID and NFC approaches
(05/25/2008)
Intelligent environments need interactions capable of detecting users and providing them with goodquality contextual information. In this sense we adapt technologies identifying and locating people adjusting their requirements. ...
Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM
(11/12/2001)
A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...
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 ...
Design and tolerance analysis of a router with an amplified resonator and Bragg gratings
(04/20/2000)
A novel ring resonator configuration with Bragg gratings is presented. The stability of this configuration is studied by a z-transform technique. A router design with a FWHM of 17 MHz, a -40-dB rejection ratio, and a 15-dB ...
