Von der Milch zum festen Futter : Von der Abhängigkeit zur Selbständigkeit

Das Neugeborene ist bei Säugetieren und beim Menschen zunächst völlig von der Mutter abhängig, denn die Ernährung des oder der Nachkommen erfolgt erst einmal ganz auf Kosten der Mutter. Mit den Umstellungen auf dem Wege von der Abhängigkeit zur Selbständigkeit befassen sich die hier dargestellten Untersuchungen

Study of structure and composition of micro arc lantanum-siliconincorporated calcium phosphate coatings

The lanthanum- silicon-incorporated calcium phosphate coatings on the titanium have porous X-Ray amorphous structure. The increase of the process voltage leads to the growth of thickness and structural elements and to the formation in the coatings of crystalline phases CaHPO4 and β-Ca2P2O7

Firm Level Innovation and Productivity - Is there a Common Story Across Countries

Recent studies have documented extensive heterogeneity in firm performance within countries, and innovation has been found as an important determinant. This paper addresses the issue of innovation firm performance across countries. A growing number of national firm level studies on the innovation-productivity link have been conducted using new internationally harmonized survey data, known in Europe as Community Innovation Survey (CIS). Mainly due to confidentiality reasons cross-country comparisons of CIS data are still rare. The contribution of this paper is its unique approach of pooling original firm observations from Germany and Sweden. Applying a knowledge production function that gives the relationship between innovation input, innovation output and productivity, we find to a very large extent a common cross-country story for knowledge intensive manufacturing firms. Some interesting country-specific effects are reported as well

Распознавание изображений лиц на основе кластеризации

This article describes the use of clustering for face recognition image. Clustering was performed using a recurrent neural network used at two stages of the recognition process. The algorithm includes the recognition process itself perform clustering pixel brightness image, calculating image information close proximity and clustering measures to in order to obtain the cluster containing the original similar images
