Measurements on a passive optical fibre tunable filter are presented. The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a coupler. The novel ...

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 ...

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 ...

The paper shows the complete system architecture of a walking and climbing robot developed to make slope consolidation, where heavy duty equipment is employed for drilling up to 20m holes. ROBOCLIMBER a quadruped robot ...

In this paper, different optical configurations based on ring resonators and a reflective section in the feedback path, are proposed in order to show the feasibility of their applications in different fields. Additionally, ...

A ring resonator with multiple reflections as a tunable filter is proposed and analyzed in this paper. A coupler and two identical Bragg gratings are used to implement the internal reflections so an active filter with a ...

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 inflammable atmospheres can be benefited ...

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 ...

General filter architecture using co-and counterpropagation signals are studied. A specific configuration based on a Sagnac loop within a ring resonator is analyzed. Novel tuning, apart from conventional tuning,is achieved ...

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 ...
