The Changing Waves of Migration from the Balkans to Turkey: A Historical Account

Ahmet İçduygu and Deniz Sert tell the history of migration from the Balkans to Turkey from the end of the nineteenth century to the present. They relate this history to nation-building, but also to economic conditions and specific Turkish concerns, such as the perceived need for immigration to compensate for a declining population at that time. They also demonstrate that after 1990, ethnic migration decreased and irregular labour migration became more important

The free-end interface crack problem for bonded orthotropic layers

The plane elasticity problem of two bonded orthotropoic layers containing cracks perpendicular to and along the interface is considered. The cracks are extended to intersect the boundaries and each other in such a way that a crack configuration suitable to study the edge debonding problem associated with bonded dissimilar materials is obtained. The problem is reduced to the solution of a system of singular integral equations with Cauchy type singularities. Numerical results for stress intensity factors and energy release rates are presented for various loading conditions and for isotropic as well as orthotropic material pairs. These results indicate that elementary strength of material type calculations for energy release rates provide a very good approximation to the actual elasticity solution even for relatively short cracks under some practical loading conditions such as thermal loading, as long as the thicknesses of the layers are not very different

T-shaped crack problem for bonded orthotropic layers

The plane elasticity problem of two perfectly bonded orthotropic layers containing cracks perpendicular to and along the interface is considered. Cracks are extended to intersect the boundaries and each other in such a way that a crack configuration suitable to study the T-shaped crack problem is obtained. The problem is reduced to the solution of a system of singular integral equations with Cauchy type singularities.

3D model of wooden church of the Saint Paraskieva in Blansko

Předmětem této diplomové práce je zaměření a vyhotovení 3D modelu historické budovy. Pro tyto účely byl vybrán dřevěný kostel sv. Paraskivy v Blansku. Na úvod se práce zabývá historií a popisem kostela. Následuje popis sběru dat pro tvorbu modelu a poté je řešena samotná tvorba modelu v programu AutoCAD.The object of this diploma thesis is surveying and creation of 3D model of the historical building. For these purpouses was selected the wooden church of st. Paraskiva in Blansko. In the introduction this thesis is focused on history and description of the object. In the next part is description of the data collection for the model and than is solved the modeling issues in program AutoCAD.
