Принципы построения мультимедиа систем презентационного класса

Статья посвящена проблемам создания мультимедиа систем (ММС) презентационного класса как сегмента глобального информационного пространства (ГИП). Процесс формирования данного сегмента состоит из создания информационных ресурсов (ИР) в виде электронных мультимедиа документов и их интеграции в ГИП. Ставится задача определения основных характеристик презентационных ММС, а также принципов их построения, исходя из современных требований интеграции в глобальное информационное пространство. Дается описание систем этого класса, представлены принципы их построения, методы и средства разработки.У статті розглянуто проблеми створення мультимедіа систем (ММС) презентаційного класу як сегмента глобального інформаційного простору (ГІП).

The process of that segment formation consists of two components – creation of information resources in a form of electronic multimedia documents and their integration within global information space. The goals are the determination of the main features of presentation multimedia systems, principles of their building and integration within global information space

Review of dominant species of macrozooplakton from Bay of Biscay during spring season (from literature).

<p>All studies encompass day and night data and a sampled depth range of 100 m (method: 150- µm PairoVET net).</p

Day-night distributions of macrozooplankton.

<p>The centre of gravity (CG) of and the related inertia are analyzed according to the inshore and offshore regions. Day distributions are represented in red and night distributions in black. The black solid lines shows the smoothed distribution of the scattered data.</p

Fine scale representation of macrozooplankton diel vertical behaviour.

<p>Echograms of the macrozooplankton backscattering strength (<i>S</i>v in dB re. 1 m⁻¹) show the differences in distribution between the two diel periods, which makes it possible to define a “biocline” (red solid line) as the depth where the cumulated sum of acoustic echoes (<i>S</i>v) from the macrozooplankton community reaches 5%.</p

Overall day-night vertical profiles of physical and biological variables.

<p>Temperature (light blue solid line), salinity (black solid line), macrozooplankton biomass (red dashed line), and fish biomass (dark blue dashed line) vertical distributions are represented in inshore and offshore domains in the Spanish and French areas. The upper and lower thermocline are represented as green horizontal lines.</p

Day-night temporal correlations of macrozooplankton (CG_macro and biocline) and fish (CG_fish).

<p>Analyses were done according to inshore and offshore ecological domains. Scatter plots include a linear fit (black solid line) and loess smoothing (blue solid line) to illustrate the sign of the correlation.</p

Flow chart showing the nested and interacting nature of the environmental effects on macrozooplankton.

Along transect fine scale distribution of hydrological and biological parameters.

<p>Representation of backscattering strength (<i>S</i>v in dB re. 1 m⁻¹), stratification and fish acoustic backscattering in relation to the biocline pattern (red solid line) during the survey period (transect 5, 15 and 20). The upper and lower limits of the thermocline layer are represented by white dotted line.</p

Study area.

<p>River mouths, shelf areas (coasts) and ecological domains (inshore-offshore) are indicated. The dotted lines show the survey track. T1, T15 and T25 refer to transects presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0088054#pone-0088054-g007" target="_blank">Figure 7</a>.</p

Correlations between biocline and the environmental variables according to the diel period, the area (Spain or France) and the ecological domains (inshore, offshore).

<p>Asterisks indicate significant difference: *: <0.05; **: <0.01; ***:<0.001; NS: not significant.</p
