Properties of seawater and particulate matter from a FRRF instrument, operating in a flow-through mode on the continuous surface water sampling system during the Tara Oceans expedition 2009-2013

The Tara Oceans Expedition (2009-2013) sampled the world oceans on board a 36 m long schooner, collecting environmental data and organisms from viruses to planktonic metazoans for later analyses using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set provides continuous measurements made with a FRRF instrument, operating in a flow-through mode during the 2009-2012 part of the expedition. It operates by exciting chlorophyll fluorescence using a series of short flashes of controlled energy and time intervals (Kolber et al, 1998). The fluorescence transients produced by this excitation signal were analysed in real-time to provide estimates of abundance of photosynthetic pigments, the photosynthetic yields (Fv/Fm), the functional absorption cross section (a proxy for efficiency of photosynthetic energy acquisition), the kinetics of photosynthetic electron transport between Photosystem II and Photosystem I, and the size of the PQ pool. These parameters were measured at excitation wavelength of 445 nm, 470nm, 505 nm, and 535 nm, allowing to assess the presence and the photosynthetic performance of different phytoplankton taxa based on the spectral composition of their light harvesting pigments. The FRRF-derived photosynthetic characteristics were used to calculate the initial slope, the half saturation, and the maximum level of Photosynthesis vs Irradiance relationship. FRRF data were acquired continuously, at 1-minute time intervals.

Desarrollo de aplicaciones basadas en Linux Embedded en una arquitectura basada en Cyclone V SoC (System on Chip) de Altera

We attempt to integrate and start up the set of necessary tools to deploy the design cycle of embedded systems based on Embedded Linux on a "Cyclone V SoC" made by Altera. First, we will analyze the available tools for designing the hardware system of the SoCkit development kit, made by Arrow, which has a "Cyclone V SoC" system (based on a "ARM Cortex-A9 MP Core" architecture). When designing the SoCkit board hardware, we will create a new peripheral to integrate it into the hardware system, so it can be used as any other existent resource of the SoCkit board previously configured. Next, we will analyze the tools to generate an Embedded Linux distribution adapted to the SoCkit board. In order to generate the Linux distribution we will use, on the one hand, a software package from Yocto recommended by Altera; on the other hand, the programs and tools of Altera, Embedded Development Suite. We will integrate all the components needed to build the Embedded Linux distribution, creating a complete and functional system which can be used for developing software applications. Finally, we will study the programs for developing and debugging applications in C or C++ language that will be executed in this hardware platform, then we will program a Linux application as an example to illustrate the use of SoCkit board resources. RESUMEN Se pretende integrar y poner en funcionamiento el conjunto de herramientas necesarias para desplegar el ciclo de diseño de sistemas embebidos basados en "Embedded Linux" sobre una "Cyclone V SoC" de Altera. En primer lugar, se analizarán las diversas herramientas disponibles para diseñar el sistema hardware de la tarjeta de desarrollo SoCkit, fabricada por Arrow, que dispone de un sistema "Cyclone V SoC" (basado en una arquitectura "ARM Cortex A9 MP Core"). En el diseño hardware de la SoCkit se creará un periférico propio y se integrará en el sistema, pudiendo ser utilizado como cualquier otro recurso de la tarjeta ya existente y configurado. A continuación, también se analizarán las herramientas para generar una distribución de "Embedded Linux" adaptado a la placa SoCkit. Para generar la distribución de Linux se utilizará, por una parte, un paquete software de Yocto recomendado por Altera y, por otra parte, las propias herramientas y programas de Altera. Se integrarán todos los componentes necesarios para construir la distribución Linux, creando un sistema completo y funcional que se pueda utilizar para el desarrollo de aplicaciones software. Por último, se estudiarán las herramientas para el diseño y depuración de aplicaciones en lenguaje C ó C++ que se ejecutarán en esta plataforma hardware. Se pretende desarrollar una aplicación de ejemplo para ilustrar el uso de los recursos más utilizados de la SoCkit.

Investigations into an optimal transmission scheme for a MIMO system operating in a ricain fading environment

This paper describes investigations into an optimal transmission scheme for a multiple input multiple output (MIMO) system operating in a Rician fading environment. The considerations are reduced to determining a covariance matrix of transmitted signals which maximizes the MIMO capacity under the condition that the receiver has perfect knowledge of the channel while the transmitter has the information about selected statistical quantities which are measured at the receiver. An optimal covariance matrix, which requires information of the Rice factor and the signal to noise ratio, is determined. The transmission scheme relying on the choice of the proposed covariance matrix outperforms the other transmission schemes which were reported earlier in the literature. The proposed scheme realizes an upper bound limit for the MIMO capacity under arbitrary Rician fading conditions. ©2005 IEEE
