Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...

Abstract—The paper is focused on monitoring of dependencies of different composition concretes on elastic modulus values. To obtain a summary of elastic modulus development in dependence of concrete composition design variability was the objective of the experiment. Essential part of this work was initiated as a reaction to building practice when questions of elastic moduli arose at the same ti...

The DiaMODL dialog modelling is a hybrid language, based on the Pisa interactor abstraction and UML Statecharts. By combining a dataflow-oriented language with one focussing on behavior, we get a flexible notation which may be used for different purposes, interaction styles and platforms. DiaMODL may be used as a pure abstract notation for modelling dialog or more directly for modelling concret...

We present a design approach for hardware-oriented selfsynchronizing stream ciphers and illustrate it with a concrete design called Moustique. The latter is intended as a research cipher: it proves that the design approach can lead to concrete results and will serve as a target for cryptanalysis where new attacks may lead to improvements in the design approach such as new criteria for the ciphe...
