An in-depth knowledge of solutes advection and turbulent diffusion is crucial to estimate dispersion area and retention time (t(R)) of pollutants within seagrass habitats. However, there is little knowledge on the influence of seagrass habitat fragmentation on such mechanisms. A set of dye tracer experiments and acoustic Doppler velocimeter measure...

This paper is about a new online monitoring system for PV system operators based on the SCADA operational philosophy. The analysis module in the SCADA system manages the information using OLAP cubes, thus it allows improving the query of big data quantities and realize multidimensional analyses in an efficient way. For fail detection this paper pro...

Terology is a concept introduced to synthesize all the actions related to the managing of the life cycle of facilities and equipment as an enlarged maintenance perspective. Nowadays, the concept tries to give some contribution to integrate the environment in this approach. The concept has been implemented in several fields, namely for wind mills in...

The Cramer-Rao lower bound (CRLB) for the estimations of the cosine and sine amplitudes of multi-tone sinusoidal model is derived and applied on TOPEX/Poseidon satellite altimetry data sets covering the Indian Ocean. The CRLB depends on the variance of the White Gaussian Noise that it is computed by Modern Parametric Autoregressive Adaptative Spect...

The generation of internal lee waves (ILW) in the Strait of Gibraltar takes place in the main sill where the tidal flow interacts with a submarine obstacle. The tidal flow is perturbed by subinertial phenomena of different nature summarized in the subinertial currents that can inhibit the ILW generation. The authors present an attempt to randomize...

Tidal mills were the main industrial activity in the Bay of Cadiz for centuries. They were the last step in the production of salt and flour made by grinding grains. They were installed along the shallow channels, called “canos”, around the Bay, where the frictional and geometrical effects are very strong. The authors have analyzed the propagation...

A linear theory for the physical fields in the water column under the action of large amplitude internal lee waves at the main sill of the Strait of Gibraltar is developed. The procedure is a combination of the perturbation and normal modes methods in order to study steady resonant conditions. The lowest order linear approach of the methodology res...

Fractal Geometry is one of the most powerful tools in the research of complex dynamical systems of high, fractional or unknown dimensions. It allows the computation of the dimensions of attractors of the phase space of the dynamical system and their stability. The authors apply some fractal concepts on tidal elevation data sets considering them as...

The main sill of the Strait of Gibraltar (Camarinal Sill) is an area of very energetic internal wave activity. The highest amplitude internal wave is the well-known internal bore, generated at critical conditions over Camarinal Sill. A very energetic lee wave has recently been found and reported. This occurs in neap tides when favorable combination...
