The impact of concrete composition and roughness on the formation microalgal biofilms their photobiology were studied marine infrastructures presenting four different compositions combined with two degrees (rough smooth). structures first inoculated a natural microphytobenthic biofilm immersed in sterilised seawater controlled photoperiod for six days. Photosynthetic activity was assessed an im...

I will start this treatise with a history of two major themes in data integration. In my opinion, the topic began with the major retailers in the 1990s consolidating their sales data into a data warehouse. To do this they needed to extract data from in-store sales systems, transform it into a predefined common representation (think of this as a global schema), and then load it into a data wareh...

In order to automate the scooping task, it is desirable that the resistive force acting on the bucket be obtained before the scooping is performed. The objective of this study is to derive theoretically the resistive forces acting on the bucket during scooping of piled rock fragments. First, the changes in the shape of the rock pile due to the penetration of it by the bucket are modeled. Based ...

Bas-reliefs are a form of flattened artwork, part-way between 3D sculpture and 2D painting. Recent research has considered automatic bas-relief generation from 3D scenes. However, little work has addressed the generation of bas-reliefs from 2D images. In this paper, we propose a method to automatically generate bas-relief surfaces from frontal photographs of human faces, with potential applicat...

Reverse engineering of reliefs aims to turn an existing relief superimposed on an underlying surface into a geometric model which may be applied to a different base surface. Steps in this process include segmenting the relief from the background, and describing it as an offset height field relative to the underlying surface. We have previously considered relief segmentation using a geometric sn...

When Sennacherib's conquest of Lachish is considered, the vivid reliefs depicting that event which were found in the ruins of his palace at Nineveh immediately come to mind.' These are, however, simply pictorial representations; they do not include any verbal description of any significant length of the events depicted. For instance, the cuneiform label which accompanies one of the scenes says ...

Azopolymer films exposed to nonuniform illumination exhibit a phenomenon of light-induced mass transport, leading to the formation of permanent relief patterns on the film surface. Its underlying microscopic mechanism remains unclear, despite many years of research effort. Here we introduce a model of the mass migration process based on anisotropic light-driven molecular diffusion. A key ingred...
