Replacement of headlamp parts screw fixation by a plastic nail
Lysa, Bohuslav ; Píška, Miroslav (referee) ; Polzer, Aleš (advisor)
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.

Geo-oriented mathematical modelling: multiphysics and multiscale
Blaheta, Radim
This contribution is aimed at a brief introduction to two important aspects of nowadays geo-oriented mathematical modelling: multiphysics and multiscale. Moreover, these types of modelling are illustrated on problems currently solved at the Institute of Geonics AS CR.The multiphysics means modelling of coupled physical phenomena. In the case of the geotechnical engineering, it is typically modelling of coupled thermo-hydro-mechanical (THM) processes, in other engineering branches, we can consider similar models, e.g. coupling of electric and mechanical phenomena. The modelling of coupled processes is particularly involved in modelling of sealing and plugging effects of bentonite barriers used in the design of underground repository of spent nuclear fuel. At present, the team at the Institute of Geonics is involved in the solution of Task A of the Decovalex 2015 project aimed at modelling in-situ SEALEX experiments, which were performed in Tournemire underground laboratory in France.
